Description

The invention relates to a screw or plug-in system, a female and male screw or circular connector and a method for producing a screw or circular connector.

The invention is in the field of connector technology, in particular in the field of circular connectors, ie connectors with, for example, an M12, M8, M23 or a 7/8 "thread Such circular connectors, in particular M12 circular connectors are, for example Furthermore, such circular connectors are often exposed to mechanical stresses, such as vibrations caused by connected machines, which is why these circular connectors should be designed for mechanical loads and in particular have a threaded threaded ring with which the plug connection can be screwed and secured DE 10 2015 014 492 A1 For example, such a circular connector is described.

Circular connectors are usually arranged on a cable end and are used for contacting a complementary circular connector and / or a complementary circular connector socket. An important feature of circular connectors is their shielding property against electromagnetic radiation to thereby ensure a high quality of the signals transmitted through the connector. For this purpose, the circular connector has a corresponding shield housing. The shielding effect can be enhanced by the shield housing is electrically connected to the screw ring of the connector. An electrical connection of the screen housing with the threaded ring of the connector is also important so that when screwing the connector together with a complementary connector, the respective shield housing via the bolted screw rings are electrically connected together.

Conventionally, this is achieved in that the screw ring of a circular connector in the fully screwed together or assembled state directly contacted the shield housing of the circular connector.

In the context of the present invention, however, it has been found that in practice the connectors to be connected are not always completely screwed together or are e.g. the screw connection loosens or loosens as a result of vibrations or mechanical stress. This can have the consequence that the screening effect of the plugged together or bolted connector decreases, since the electrical contact between the screw ring and screen housing deteriorates or no longer exists.

It is therefore an object of the present invention to provide a female and male screw connector and system, respectively, which have an improved and reliable shielding effect. In addition, a method for producing an improved screw connector is to be specified.

This object is solved by the subject matters of the independent claims. Preferred embodiments of the invention are the subject of the dependent claims.

• - ein männliches Schirmgehäuse zum zumindest teilweise Abschirmen des männlichen Schraubverbinders; wobei

der weibliche Schraubverbinder einen weiblichen Schirmkontaktring aufweist, welcher in einem montierten Zustand den weiblichen Schraubring und das weibliche Schirmgehäuse elektrisch miteinander verbindet, und/oder
der männliche Schraubverbinder einen männlichen Schirmkontaktring aufweist, welcher im montierten Zustand den männlichen Schraubring und das männliche Schirmgehäuse elektrisch miteinander verbindet.A first independent aspect for achieving the object relates to a screw system with a female screw connector and a male screw connector, which are screwed together, wherein the female screw connector comprises:

• - A female threaded ring with a male end, into which a male screw ring of the male screw connector is screwed, and
• a female shield housing for at least partially shielding the female screw connector;

wherein the male screw connector comprises:

• - The male screw ring with a male end, which is screwed into the male end of the female screw ring, and
• a male shield housing for at least partially shielding the male screw connector; in which

the female screw connector has a female shield contact ring which in an assembled state electrically connects the female screw ring and the female shield housing, and / or
the male screw connector has a male shield contact ring which in the mounted state electrically connects the male screw ring and the male shield housing.

The female screw or plug connector and the male screw or plug connector are designed and provided with their plug-in end in the insertion direction inserted into one another and / or screwed, whereby they enter into a plug or screw connection with each other. The male screw connector is formed substantially complementary to the female screw connector and vice versa.

The screw system can be designed in particular as a system with M12 screw or plug connectors. Both the female and the male screw connector each have a screw ring and a, in particular cylindrical, shield housing.

The tightening system may include other elements, such as e.g. one or two insulating bodies, one or two sealing rings for sealing the connectors and / or one or two inhibiting rings which hinder and / or reduce inadvertent release of the connector, i. for securing the plug connection.

In particular, the female screw connector and the male screw connector can be inserted into each other along with a plug-in end along a plug-in direction. In this case, the female screw connector in addition to the female screw ring and the female shield housing preferably has a female insulating body which can be arranged in the interior of the female screw ring and which can be inserted along the insertion direction into a male insulating body of the male screw connector. Accordingly, the male screw connector in addition to the male screw ring and the male shield housing preferably on the male insulating body, which can be arranged in the interior of the male screw ring and in which the female insulating body along the insertion direction can be inserted.

The female screw connector has a male end, and an end (e.g., cable end) remote from the male end, on which a cable may be disposed. The male end of the female connector may be configured and provided to be inserted into the male end of the male connector. Facing away from the male end of the male connector, the male connector has an opposite end (e.g., cable end) to which a cable may be attached to the male screw connector.

The female and male screw ring are complementary to each other and designed to be screwed into each other and / or each other, thereby securing a plug connection. The female and male screw ring are at least partially or completely formed of a conductive material, in particular of metal. Inside each of the two screw rings, a female or male insulator, i. an electrically non-conductive element, be arranged. Both insulators may substantially have the shape of a cylinder around which the respective screw ring is arranged. The respective screw ring can be rotatably arranged about the cylinder axis of the respective insulating body, which can coincide with the plug-in direction and the ring interior of the respective screw ring is arranged piercing. Each screw ring and each insulating body may also each have a plug-in end, which is in each case designed and provided to physically contact the plug-in end of the respective complementary component.

The female insulating body may include female electrical contacts (e.g., contact sockets and / or female contact pins) into which male electrical contacts of the male insulating body are inserted when the two screw connectors are mated together. As is common with M12 connectors, the female insulator may have a plurality of female electrical contacts, e.g. five.

The male insulating body may also have a plurality of male electrical contacts (e.g., contact pins), for example the same number as the female insulating body, in the example also five. Both male and female electrical contacts may be electrically and / or physically connected to wires of a cable, each of which may be disposed on the end of the insulator. In this case, the tail is arranged opposite the insertion end opposite. When the two screw or plug connectors make a plug connection with each other, the male contacts contact the female contacts and vice versa both electrically and physically.

The female and the male insulating body are complementary to each other and intended to be inserted into each other. The insulating body are formed of an electrically insulating material, for example of a plastic. The insulators provide electrical insulation between the individual electrical contacts, between the screw ring (s) and the electrical contacts, and optionally also between the screen (s) and the electrical contacts.

By screwing the two screw rings, the connector is secured against mechanical stresses, e.g. to vibration of a machine and / or inadvertent loading of the cable, such as tripping over the cable.

Each of the two insulating bodies may have a plug-in end which is designed to enter into the plug connection with the plug-in end of the associated second insulating body. At the opposite end of the respective insulator each end piece is arranged with a constant outer diameter. This end piece can in each case be arranged adjacent to the cable, with which the electrical contacts of the insulating body are contacted. Both end pieces, ie both the end piece of the male insulating body and the end piece of the female insulating body, may have the same constant outer diameter. This makes it possible to set up a shielding housing of the same design on both end pieces. In other words, a shield housing can be plugged onto the end piece of the female insulating body, which is constructed identically to a second shield housing which can be plugged onto the end piece of the male insulating body.

The female and male shield housings are electrically conductive, in particular made of metal, in order to provide the required electrical shielding effect. Furthermore, the shield housing is formed substantially in the form of an elongated cylinder having only a cylinder jacket, but neither a cylinder bottom nor a cylinder cover. The female and male shielding housings are thus substantially tubular.

In the context of the invention, "property" is essentially fulfilled if this property is fulfilled to at least 90%, preferably to at least 95%, particularly preferably to at least 99%. In particular, this property can be 100% satisfied.

Thus, the umbrella housing is substantially in the shape of a cylinder with no bottom and lid, that the shape of the screen housing at least 90%, preferably 95%, etc. corresponds to that of such a cylinder. In this cylinder, however, for example, small holes and / or grooves may be formed which deviate from the hundred percent strict shape of a cylinder.

The same or the like applies to the inner diameter of the screen housing, which is preferably substantially constant, ie not more than 10%, preferably 5%, or more preferably deviates by a maximum of 1% from its constant value. The inner diameter is also constant over substantially the entire cylinder height, i. over at least 90%, 95%, 99% or 100% of the total cylinder length. For example, at one end the shield housing may be slightly flared to facilitate attachment of the shield housing to the tail. Therefore, the inner diameter and outer diameter of the shield case and the end piece do not have to correspond 100%, or even exactly over 100% of the length of the shield case.

The inner diameter of the shield housing can be matched to the predetermined outer diameter of the two end pieces. These diameters and in particular the components of the insulating body and shielding housing are preferably coordinated so that in each case a shielding housing can be placed on one of the end pieces of an insulating body.

Here, the shape of the insulating body can be formed as simple as possible. Namely, the shape of the insulating body may substantially correspond to that of a cylinder having a constant cylinder diameter. Furthermore, the two screen housing can be constructed identical, which allows a simplified production of the shield housing.

The end piece of the female insulating body and the end piece of the male insulating body may be formed and provided to be inserted into an associated shield case whose inner diameter is formed less than 5% larger than the predetermined outer diameter of the two end pieces. The outer diameter of the end pieces can be matched to the inner diameter of the shield housing. This means that the two diameters essentially correspond, that is, they are substantially the same size. In this case, the inner diameter of the shield housing may be formed a little larger than the outer diameter of the end pieces to allow easy insertion of the components into each other.

The female screw connector has a female shield contact ring which in an assembled state electrically connects the female screw ring and the female shield housing. Alternatively or additionally, the male screw connector has a male shield contact ring, which in the mounted state electrically connects the male screw ring and the male shield housing.

In the context of the present description, a mounted state is understood to mean a state in which the female or the male screw connector is used as intended and / or is properly mounted, assembled or screwed together. In particular, a mounted state is understood to mean that the female or male screw connector is screwed together with a complementary screw connector. An assembled state can therefore also as assembled state, assembled state, bolted state and / or be referred to as operating state. In other words, the assembled state of a screw or screw system denotes a proper arrangement or installation position of the individual elements of the screw or screw.

In other words, the female shield contact ring is designed and / or provided to electrically connect the female screw ring and the female shield housing, in particular in an assembled state. Accordingly, the male shield contact ring is designed and / or determined to electrically connect the male screw ring and the male shield housing, in particular in an assembled state. The female and male shield contact ring are at least partially or completely formed of a conductive material, in particular of metal.

The shield contact ring is in addition to the screw ring basically a separate element of the screw. However, the shield contact ring can be inserted into the interior of the screw ring and connected in a rotationally fixed manner to the screw ring and / or fixed thereto. In particular, the screen contact ring is inserted into the interior of the screw ring in the assembled state and rotatably connected to the screw ring and / or fixed thereto.

Compared to conventional circular connectors, in which the screw can only contact the screen housing of the circular connector in fully assembled or assembled state, the physical and electrical contact between the screw ring and screen housing is done according to the invention alternatively or additionally to direct contact via an extra for the electrical contact provided shield contact ring.

Thus, it is advantageously ensured that even if the screw ring is not completely screwed or when the screw ring loosens or loosens something, there is an electrical contact between screw ring and shield housing. In this way, an improved and reliable shielding effect can be achieved.

In a preferred embodiment, the female shield contact ring is arranged in the mounted state in a guide groove of the female screw ring. Alternatively or additionally, the male shield contact ring is arranged in the assembled state in a guide groove of the male screw ring. The guide groove is arranged in each case in the interior or on an inner surface of the female and male screw ring. In other words, the female screw ring for receiving the female shield contact ring and the male screw ring for receiving the male shield contact ring is formed. In the assembled state of the female or male shield contact ring with the female or male screw ring is rotatably connected.

In a further preferred embodiment, the female shield contact ring on at least a first female spring element, which in the mounted state, the female shield housing, in particular an edge region or a shoulder of the female shield housing, contacted. Alternatively or additionally, the male shield contact ring has at least one first male spring element, which in the assembled state contacts the male shield housing, in particular an edge region or a shoulder of the male shield housing. Preferably, the female and the male shield contact ring are each formed as an open ring, in particular as a snap ring. Further preferably, each of the first spring element is formed at an end portion of the open ring. The at least first female or male spring element is preferably designed and / or provided, in the mounted state, to contact the female or male shielding housing, in particular an edge region or a shoulder of the female or male shielding housing. In this case, the at least first spring element is deformed resiliently in the assembled state, i. compressed or compressed, so that it exerts a certain restoring force on the screen housing or a shoulder thereof due to its resilient and in particular elastic properties. This advantageously causes improved electrical contact between the shield housing and the screw ring. Since the shield contact ring is rotatably connected in the assembled state with the screw ring, the shield contact ring and thus the at least one spring element moves when screwing in and unscrewing the screw relative to the shield housing and thus forms a sliding contact.

The female shield contact ring has a second female spring element, which contacts the female shield housing in the mounted state. Alternatively or additionally, the male shield contact ring on a second male spring element which contacts the male shield housing in the mounted state.

In particular, the second female and male spring members have the same features as the first female and male spring members described above except that the second female and male spring members is not disposed on an end portion of the Schirmkontaktaktrings, but preferably at a central portion of the Schirmkontaktaktrings.

The female screw ring has a mating engagement and the female shield contact ring has an associated fastener which, when assembled, is disposed in the mating engagement of the female screw ring. Alternatively or additionally, the male screw ring has a fastening engagement and the male shield contact ring has an associated fastening element, which in the mounted state is arranged in the fastening engagement of the male screw ring. The fastening engagement is formed on an inner surface of a screw ring. With the help of the fastening engagement and the fastening element, the shield contact ring can be connected in a rotationally fixed manner to the respective screw ring or fixed thereto.

The second female spring element is part of the fastening element of the female shield contact ring. Alternatively or additionally, the second male spring element is part of the fastening element of the male shield contact ring. In particular, the attachment element of a shield contact ring preferably has two attachment lugs and the second spring element. The mounting lugs are designed and provided to be brought into engagement with the fastening engagement of the screw ring and thus to fix the screen contact ring on the screw rotatably. Preferably, the second spring element, in particular as a projection or tongue, extends substantially radially into the interior of a screen contact ring, i. substantially perpendicular to the insertion direction to contact the screen housing in the assembled state. In particular, the second spring element is designed and provided to press in the mounted state with a certain restoring force on the screen housing or an edge region or a shoulder of the screen housing. Like the first spring element, the second spring element also acts as a sliding contact.

With the help of the second spring element, the electrical contact between the shield housing and screw ring in the assembled state can be further improved. The same also applies to the shielding effect of the female or male screw connector or the screw system.

In a further preferred embodiment, the female shield housing has a screening on an outer surface of the female shield housing. Further, the female shield contact ring on a female inhibitor which is engageable with the screening of the female shield housing or which is in the assembled state in engagement with the screening of the female shield housing. Alternatively or additionally, the male shield housing has a screening on an outer surface of the male shield housing. Further, the male shield contact ring on a male inhibitor, which is engageable with the screening of the male shielding housing or which is in the mounted state in engagement with the screening of the male shielding housing. The female and male inhibitor are preferably formed as a spring element. In this way, the female or male umbrella contact ring advantageously also serves as Hemmring.

In a further preferred embodiment, the female screw connector further comprises a female insulating body which can be arranged in the interior of the female screw ring and which can be inserted along a plug-in direction into a male insulating body of the male screw connector.

Accordingly, the male screw connector further comprises the male insulating body, which is arrangeable in the interior of the male screw ring and in which the female insulating body along the insertion direction can be inserted. The female insulating body has a ratchet on its outer surface and the female shield contact ring has a female inhibiting member which is engageable with the grid of the female insulating body or which is in the mounted state in engagement with the grid of the female insulating body. Alternatively or additionally, the male insulating body has a screening on its outer surface and the male shield contact ring on a male inhibitor, which is engageable with the screening of the male insulating body or in the assembled state in engagement with the screening of the male insulating body. In this way, the female or male umbrella contact ring advantageously also serves as Hemmring. The shield contact ring or Hemmring can engage by means of the Hemmelements in the associated screening of the insulator. Here, the outer surface of the insulating body faces the inner surface of the associated screw ring.

About the shield contact ring, which additionally acts as Hemmring by engaging by means of Hemmelements in the screening of the screen housing or insulating, the bolted connector is advantageously secured against unintentional unscrewing and thus against inadvertent release of the connector. In particular, since circular connectors are often used for the electrical connection of heavy machinery, these connectors are often exposed to vibration, the screw over the Solve time. With the help of a screen ring acting as Hemmring thus both the shielding effect and the stability of a female and male screw or a screw system can be improved in a simple and cost-effective manner.

In a further preferred embodiment, the female shield contact ring is formed as an open ring or as a snap ring with a first and second end portion. The first female spring element is formed at the first end portion of the female shield contact ring, and the female inhibitor is formed at the second end portion of the female shield contact ring. Alternatively or additionally, the male shield contact ring is formed as an open ring or snap ring with a first and second end portion. The first male spring element is formed on the first end portion of the male shield contact ring and the male inhibitor is formed on the second end portion of the male shield contact ring.

In a further preferred embodiment, the first female spring element and the female retainer are each formed as a taper of the female shield contact ring. In addition, the first female spring member is spaced apart with respect to the female inhibitor member along an axial direction of the female umbrella contact ring d added. Preferably, the distance is d about 1 mm. In the assembled state is thus the first female spring element with respect to the female Hemmelements in the direction of the female shield housing, ie in the insertion direction e , offset. Alternatively or additionally, the male inhibitor is formed as a taper of the male shield contact ring to be engaged only in the assembled state only with the grid of the male insulating body, while the first male spring element contacts the male shield housing.

In this way it is possible with only a single additional element, namely with the help of the Schirmkontaktaktrings, to improve both the shielding and the stability of the female and male screw connector or the screw system.

Here is the plug e defined as the direction in which the female screw connector 100 must be moved to a plug connection with the male screw connector 200 enter into. The insertion direction e is arranged parallel to a non-marked center axis of the screw connector. The insertion direction e is arranged substantially parallel to the current flow direction during current flow from a screw connector to a complementary screw connector connected to the screw connector.

The female screw connector 100 is designed as a female screw connector, that is, this screw connector female socket contacts 110 having. The male screw connector 200 is designed as a male screw connector, which means that the screw connector male socket contacts 210 having. The male socket contacts 210 of the male screw connector 200 are designed and intended to do so in the female socket contacts 110 of the female screw connector 100 to be inserted and plugged in, that in each case a male socket contact 210 in electrical contact with an associated female socket contact 110 stands. The contact can be provided by a mechanical and / or an electrical contact.

The female screw connector 100 has a female shield housing 170 (see also 5 ) and a female screw ring 160 (See also the 7A and 7B) on. In addition, the female screw connector 100 , as in 2 shown a female insulator 120 (see also 3 ), the female socket contacts 110 , an outer sleeve 180 and a cable (not shown in the figures) to which the female receptacle contacts 110 can be electrically connected. The individual components of the screw connectors can be around the cable to the outer shell 180 be splashed.

The male screw connector 200 has a male shield housing 270 (see also 5 ) and a male screw ring 260 (See also the 8A and 8B) on. In addition, the male screw connector 100 , as in 2 shown a male insulating body 220 (see also 4 ), the male socket contacts 210 , an outer sleeve 280 and a cable (not shown in the figures) to which the male receptacle contacts 210 can be electrically connected.

The sealing ring 140 serves to seal the plug connection. Furthermore, the female screw connector 100 also an optional Hemmring 150 on, which enlarges in 6 is shown and described in more detail below. Also the male screw connector 200 can a corresponding sealing ring (in the embodiment of 2 not included) and / or an inhibitor ring 250 respectively.

The female screw connector 100 can have several female socket contacts 110 each having a wire or a strand of a cable, not shown, may be connected. Analogously, the male screw connector 200 several male socket contacts 210 have, each of which may be electrically connected to wires or strands of a cable.

The in the 1 and 2 Screw connectors shown are designed as five-pin M12 screw. Such M12 Screw connectors are used, among other things, for connecting industrial Ethernet networks. M12 screw connectors are exposed to different mechanical loads, such as vibration loads from connected industrial machines. This is why M12 screw connectors preferably fulfill tensile and compressive loads. Thus, the screw connectors have, among other things, the screw rings 160 and 260 to provide a secure screw connection between the male screw connector and the female screw connector. Mechanically stabilized and / or supported the connectors are further by a deep penetration of the male socket contacts 210 into the female socket contacts 110 ,

The individual components of a conventional screw connector are in the following 3 to 8B described in more detail.

3 shows the female insulator 120 a female screw connector 100 , The female insulator 120 is designed essentially as a solid cylinder, which is opposite to the insertion direction e at his shank end 120E in a face 127 ends. Alternatively, the female insulator 120 also have another substantially massive, elongated shape, for example with a square or hexagonal cross-section. The face 127 is substantially perpendicular to the insertion direction e arranged and trained. At the longitudinal end of the female insulator 120 that from the frontal area 127 facing away, the female insulating body 120 a cable end 120K on, where the female socket contacts can be connected by a cable. The face 127 is in an insertion position facing the (not shown) male screw connector.

The female insulator 120 has a plug-in area 121 up, extending from the frontal area 127 approximately to the middle of the insulator 120 contrary to the insertion direction e can extend. The plug-in area 121 is designed and intended, in a plug-in connection in an opening 227 and in a plug-in area 221 of the male insulating body 220 a male screw connector to be introduced (see also 4 ). The plug-in area 121 is formed substantially in the form of a solid cylinder, the cylinder axis parallel to the insertion direction e is arranged. The plug-in area 121 has at one point of its outer surface a groove 126 on, in the cylinder jacket of the plug-in area 121 is formed and parallel to the insertion direction e is trained. The groove 126 is designed and intended to, in a plug connection with a projection 226 of the male insulating body 220 to be brought together (cf. 4 ). The groove 126 , and the lead 226 serve to clearly define the alignment of the male and female screw to each other to ensure a secure contact between each associated male and female socket contacts.

In the face 127 are several insertion holes 123 educated. Behind each of the insertion holes 123 is inside the insulator 120 formed a cavity in the form of a rod cylinder, within each of which a female socket contact 110 is arranged (see also 2 ).

At the end face 127 opposite side of the insulating body 120 is a connection area 122 formed within which the socket contacts 110 can be contacted with wires of a cable electrically and mechanically. In the transition area between plug-in area 121 and connection area 122 is on the outside of the female insulator 120 a rasterization 124 educated. The screening 124 has a plurality of teeth and depressions, which may be formed, for example, in a triangular shape. The screening 124 serves to inhibit a screw securing the connector, which is described in more detail in the following figures.

The screening 124 , and in particular the teeth of the grid 124 are radially from the outer surface of the female insulating body 120 from and serve as a stop for the sealing ring 140 , which is part of the plug-in area 121 of the female insulator 120 is laid. The sealing ring 140 springs on the one hand, the connector between two screw connectors off, on the other hand, the sealing ring 140 ensure a certain moisture density of the plug connection, eg according to protection class IP67.

The connection area 122 is essentially designed as a solid cylinder with a constant outer diameter. This forms the connection area 122 an end piece of the female insulating body 120 having a substantially constant outer diameter to which the shield housing 170 (see. 5 ) can be placed.

The female insulator 120 still has a knob 125 on its outer surface, which is in a recess 172 of the screen housing 170 can be introduced and to align the screen housing 170 relative to the female insulator 120 is trained. In the embodiment shown, the nub is 125 adjacent to the grid 124 at the connection area 122 formed, ie at the end of the female insulator 120 with constant outside diameter.

4 shows in a perspective view of the male insulating body 220 of the male screw connector 200 , The male insulating body 220 has a substantially cylindrical outer surface, wherein the cylinder axis parallel to the insertion direction e is arranged. Alternatively, the male insulating body 220 also have another substantially elongated shape which is complementary to the female insulating body, for example with a square or hexagonal cross-section.

The male insulating body 220 indicates at its not shown female screw connector 100 associated end of the opening 227 on, which is to take up the in 3 shown female insulator 120 a female screw connector 100 serves. The male insulating body 220 is essentially designed as an elongated cylinder, in the insertion direction e at his shank end 220E with the opening 227 ends. The insertion end 220E is substantially perpendicular to the insertion direction e arranged and trained. At the longitudinal end of the male insulating body 220 , that from the insertion end 220E facing away, the male insulating body 220 a cable end 220K on, where the male socket contacts can be connected by a cable. The opening 227 is in a plug-in position to the female screw connector (not shown) 100 facing.

In the opening 227 are several parallel to the insertion direction e arranged male socket contacts 210 arranged so that in each case their insertion end of the female screw connector, not shown 100 is facing.

The male insulating body 220 points inside the opening 227 on one side the projection 226 on, which may be formed as a guide groove, for guiding and correct orientation of the groove 126 of the female insulator 120 which may be formed as a corresponding complementary counterpart. One of the opening 227 facing part of the male insulating body 220 is as a plug-in area 221 formed, which is formed substantially cylinder jacket-shaped. Inside the plug-in area 221 are the male socket contacts 210 arranged. One from the opening 227 spaced part of the insulating body 210 is as a connection area 222 formed and may be mechanically and electrically connected to wires of a cable, not shown. Inside the male insulating body 220 are the male socket contacts 210 parallel to each other and parallel to the insertion direction e arranged (see also 2 ).

Essentially in the middle of the male insulator 220 is a screening on its outer surface along an annular area 224 educated. The screening 224 has teeth and interposed beveled indentations. The screening 224 serves, as described below, an inhibition of a screw movement of the screw ring 260 and thus to secure the connector.

The connection area 222 is essentially designed as a solid cylinder with a constant outer diameter. This forms the connection area 222 an end piece of the male insulating body 220 on which the screen housing 270 (see. 5 ) can be placed.

The male insulating body 220 still has a knob 225 on its outer surface, which is in a recess 172 of the screen housing 270 can be introduced and to align the screen housing 270 relative to the male insulator 220 is trained. In the embodiment shown, the nub is 225 adjacent to the grid 224 at the connection area 222 formed, ie at the end of the male insulator 220 with constant outside diameter.

5 shows a shield housing 170 for a female screw connector 100 , A corresponding shield housing 270 for a male screw connector 200 can be designed identical. The shield housing 170 is substantially cylindrical, more precisely substantially as a tubular cylinder jacket 174 , Here is the cylinder jacket 174 designed and provided to the female or male socket contacts 110 or. 210 at least at their wiring area 122 or. 222 and if necessary, electrically shield connected wires of a cable from the outside. The shield housing 170 may be formed of a metallic material and the screw connector 100 or. 200 against interference with adjacent cable lines or similar shield. The cylinder jacket 174 has a constant inner diameter substantially over the entire cylinder height. In particular, the shield housing 170 no widened or tapered screen area, but is essentially formed as a piece of pipe and can the connection area 122 or. 222 Shield radially to the outside.

The shield housing 170 has at one end of the cylinder an outer stop or a shoulder 171 on, in which the cylinder jacket outwardly has a substantially annular thickening or widening. The shoulder 171 serves to stop the female or male screw ring 160 or. 260 , To form the shoulder 171 Either additional material can be provided, or the cylinder jacket 174 be bent slightly outwards. The shoulder 171 is at the cylinder end of the screen housing 170 formed, which faces the insertion end and with which the shield housing 170 ahead on the tail (ie the connection area 122 ) of the female insulating body 120 is plugged. The shield housing 270 is also with the shoulder 171 ahead on the connection area 222 of the male insulating body 220 plugged.

The shoulder 171 surrounds the cylinder jacket almost completely. At a position of the cylinder jacket 174 is in the shoulder 171 however, the recess 172 trained, in the assembly of the screw the nub 125 or. 225 of the female or male insulator 120 or. 220 is introduced, respectively.

In the cylinder jacket 174 can continue one or more holes 173 be formed, which may arise when applying a casting tool, so for example in a tin die casting process.

6 shows a conventional Hemmring 150 for a female screw connector 100 , A corresponding, eg identical Hemmring 250 for a male screw is not specifically shown in the figures, but can at a find male screw connector use, see also 2 , The inhibition ring 150 is as an open ring with an opening 153 educated. The extent of the inhibition ring 150 in the insertion corresponds approximately to the width of the grid 124 in the insertion direction e , The inhibition ring 150 is designed and intended to the screening 124 to embrace, leaving a latch 151 Intervention in the screening 124 receives. The catch 151 has substantially perpendicular to the insertion direction e radially inward toward the central axis of the screw connector.

About a fastener 152 of the inhibitor ring 150 the Hemmring is non-rotatable with the female screw ring 160 connectable, see also the 7A and 7B , For this purpose, the female screw ring 160 a fastening engagement 165 on, in which the plug-in direction e from the inhibitor ring 150 protruding fastening element 152 so engages that when turning the female screw ring 160 automatically also the Hemmring 150 with being twisted.

The inhibition ring 150 is dimensioned from its diameter so that on the one hand the screening 124 engages from the outside, and further so dimensioned that he comfortably, ie with a certain play in a guide trough 163 of the female screw ring 160 fits, cf. also the 7B , The opening 153 of the inhibitor ring 150 ensures the game for the ring radius to meet this dimensioning requirements and easy insertion of the Hemmrings 150 in the guide trough 163 to enable.

The inhibition ring 150 also has one or more thickenings 154 on that improved the seat of the Hemmrings 150 in the guide trough 163 of the female screw ring 160 guarantee. The inhibition ring 150 is conventionally made of a plastic, in particular of a hard plastic.

In an installed position or in the assembled state, the Hemmring surrounds 150 the insulating body from the outside and is positioned so that a normal through the center of the ring parallel to the insertion direction e is arranged.

The 7A and 7B show the female screw ring 160 from two different perspectives. The female screw ring 160 has on a outside a grooved handle area 161 to facilitate screwing the connector on. The screw ring 160 is essentially designed as a hollow cylinder, which at a plug-in end of a plug-in opening 162 in which the male threaded ring 260 a male screw connector is pluggable (see also 8A and 8B) , The plug-in opening 162 is dimensioned so that between a trailing edge 164 of the female screw ring 160 and the outer surface of the mating area 121 of the female insulator 120 (see also 3 ) A cylinder jacket-shaped cavity for receiving the plug-in area 221 of the insulating body 220 (see also 4 ) and a part of the male screw ring 260 a male screw connector is formed. In a part of the trailing edge 164 is the mating engagement 165 designed so that when turning the female screw ring 160 the fastener 152 of the inhibitor ring 150 entraining. The inhibition ring 150 is in the guide trough 163 arranged on the inside of the female screw ring 160 adjacent to the trailing edge 164 is trained. The screwing direction of the rotary motion is circular about the insertion direction e arranged around. Inside the female screw ring 160 can the sealing ring 140 be arranged in the 7A and 7B not shown.

On the inner surface of the cylinder jacket-shaped female screw ring 160 is an internal thread 166 formed, in which an external thread 266 of the male screw ring 260 can be screwed.

The 8A and 8B show the male screw ring 260 of the male screw connector 200 and the seat of a corresponding Hemmrings 250 in a guide trough 263 of the male screw ring 260 , Similar to the female screw ring 160 of the female screw connector 100 also has the male screw ring 260 of the male screw connector 200 a ribbed handle area 261 , a spit-out 262 , a guide trough 263 for the inhibition ring 250 , a finishing edge 264 to stop the Hemmrings 250 and a fastening engagement 265 on. In this case, the respective functions and dimensions of the components of the male and female screw connectors correspond to one another.

The screw rings 160 and 260 are rotatable around the insulator 120 or. 220 stored, so that each grip areas 161 and 261 are arranged on the outer surface of the screw connector.

To a screwing movement of the female screw ring 160 around the female insulator 120 To allow around, includes the female screw ring 160 the female insulator 120 loose, so with a game between screw ring 160 and insulator 120 , At the end of the female screw body 160 That the end of the insertion 100E of the female screw connector 100 turned away, so "back", has the female screw ring 160 an inside stop 167 on (cf. 2 ). The inner stop 167 can be as a part of the female screw ring 160 be formed with a reduced inner diameter.

Likewise, the male screw ring 260 the male insulating body 220 Loose, so with a game between screw ring 160 and insulator 120 to a screwing movement of the male screw ring 260 around the male insulator 220 to allow around. At the end of the male screw ring 260 That the end of the insertion 200E of the male screw connector 200 turned away, so "back", has the male screw ring 260 an inside stop 267 on (cf. 2 ). The inner stop 267 can as part of the male screw ring 260 be formed with a reduced inner diameter.

The interior stops 167 and 267 can slip out of the insulator 120 or. 220 from the assigned screw ring 160 or. 260 prevent.

In addition, the inner stop beats 167 of in 2 shown female screw connector 100 with shield housing 170 at the outer stop 171 of the screen housing 170 on (cf. 2 bottom right). The inner stop 267 the second male screw connector 200 with shield housing 270 hits the outside stop 171 of the screen housing 270 on (cf. 2 bottom left).

The inhibition ring 150 and the inhibition ring 250 put in conjunction with the screening 124 and 224 as well as the screw ring 160 and 260 an inhibition of the screw connection between the female screw connector 100 and the male screw connector 200 ready.

The insulator 120 and or 220 isolates the individual socket contacts 110 or. 210 against each other electrically and may consist of an elastic potting material, which also provides a friction against unscrewing the screw in addition to the locking action. The inhibition inhibits at least one screwing of the respective screw ring in the direction of rotation. In the direction of rotation, the escapement does not necessarily have to be given, but it can also at least partially inhibit a turning of the respective screw ring. By the inhibition is a turning of the screw protection of the connector, for example, in vibration load by industrial machinery o. Ä. inhibited and / or prevented. The escapement is not permanently but detachably designed and allows an intentional unscrewing of the screw.

The 9A to 9D show in four different perspective views a female shield contact ring according to the invention 130 according to a preferred embodiment. Similar to the conventional inhibition ring described above 150 is also the shield contact ring 130 designed as an open ring and thus has an opening 137 , a first end portion 139a , a second end portion 139b and a middle section 138 on. At the first end section 139a has the female shield contact ring 130 a first female contact or spring element 132 which is designed and provided in an installed position or in the assembled state of the female screw connector 100 the female shield housing 174 , in particular on or immediately beside the shoulder 171 of the female screen housing 174 , to contact. At the middle section 138 has the female shield contact ring 130 a fastener 134 on, which in its basic function the fastener 152 the conventional Hemmrings described above 150 corresponds, ie it is designed and intended, the female shield contact ring 130 rotatably with the female screw ring 160 connect to. Compared to the fastener 152 of the conventional Hemmrings 150 has the fastener 134 the umbrella contact ring according to the invention 130 but two attachment lugs 134a and 134b and a second female contact or spring element 134c on. The two attachment noses 134a and 134b are designed and provided with the fastening engagement 165 of the female screw ring 160 (see the 7A and 7B) to be engaged. The second female spring element 134c , which is formed as a projection or tongue and in the radial direction to the interior of the screen contact element 130 . d .H. in the direction of the opening 137 and / or towards the middle section 138 of the shield contact element 130 , extends, is designed and provided, in an installed position or in the assembled state, the female shield housing 170 to contact. Because the female shield contact ring 130 with the female screw ring 160 rotates, are the first and second spring element 132 . 136 each formed as a sliding contact. Advantageously, the resulting friction during a rotation of these sliding contacts that the screw connection, for example, does not easily dissolve in vibration and thus ensures increased stability and robustness. So that an electrical contact between the female screw ring 160 and the female shield housing 170 can be done is the shield contact ring 130 completely or at least partially made of conductive material, in particular metal, or formed. The conductive material may in particular be a copper alloy, which preferably has a surface coating, for example of tin, nickel, silver and / or gold. At the second end section 139b has the female shield contact ring 130 a third female spring element 136 which, due to its function, also functions as a female Inhibitor is called. The female inhibitor 136 is designed and intended, in the assembled state in a screening of the female shielding housing 170 (not explicitly shown here) or in a screening 124 of the female insulator 124 intervene to inhibit, as already mentioned above in connection with the conventional inhibitory ring 150 described, reach. The female screen contact ring 130 Thus, in addition to its function as an electrical contact element between the female screw ring 160 and the female shield housing 170 advantageously additionally the function of an inhibiting ring. The female shield contact ring according to the invention 130 thus can the conventional Hemmring 150 replace and also ensures an improved shielding effect of the screw.

Especially from the 9C is apparent, is the female shield contact ring 130 formed such that the first female spring element 132 and the female inhibitor 136 in an axial direction of the female shield contact element 130 which in the assembled state of the insertion e corresponds to a distance d offset from one another. Both the first female spring element 132 as well as the female inhibitor 136 are as a taper of the female shield contact element 130 educated. In this way, the dual functionality of the screen contact ring 130 , namely an electrical contact of the female screw ring 160 with the female shield housing 170 on the one hand and an inhibition of the female screw ring 160 On the other hand, be achieved.

10 shows in a perspective view of the arrangement of the female shield contact ring 130 the 9A to 9D inside a female screw ring 160 , In particular, the female shield contact ring 130 in an analogous manner as the Hemmring already described above 150 a conventional screw connector in the female screw ring 160 arranged. The two attachment noses 134a and 134b of the fastener 134 engage in the attachment procedure 165 of the female screw ring 160 and thus cause a rotationally fixed connection of the female shield contact element 130 with the female screw ring 160 ,

The 11A to 11C show in three different perspective views an arrangement of the female shield contact ring 130 the 9A to 9D on a female insulator 120 and the female shield housing 170 , The female screw ring 160 in which the shield contact ring 130 according to 10 was arranged in the assembled state, was for reasons of clarity in the 11 A to 11C omitted. In addition, in the 11 A to 11C but in each case an optional sealing ring 140 recognizable.

Like from the 11A to 11C it can be seen engages in the mounted state, the female inhibitor 136 into the grid 124 of the female insulator 120 and thereby causes an inhibition of a Aufdrehbewegung the (in the 11A to 11C not shown) female screw ring 160 , It can also be seen that the second female spring 134c of the female fastener 134 as well as the first female spring 132 in each case the female shield housing 170 touch or contact. By means of the female shield contact ring 130 are thus the female shield housing 170 and the (in the 11A to 11C not shown) female threaded ring 160 electrically connected together, which causes an improved shielding effect. From the 11C is particularly apparent that the first female spring element 132 the female shield housing 170 at or next to the shoulder 171 contacted.

The female screen contact ring 130 is dimensioned from its diameter so that on the one hand the screening 124 engages from the outside, and further so dimensioned that he comfortably, ie with a certain play in a guide trough 163 of the female screw ring 160 fits, cf. also the 7B , The opening 137 of the female screen contact ring 130 ensures the game for the ring radius to meet this dimensioning requirements and easy insertion of the female shield contact ring 130 in the guide trough 163 to enable.

12a shows in a perspective view a male shield contact ring 230 according to a preferred embodiment of the present invention. As well as female screen contact ring 130 is also the male screen contact ring 230 as an open ring with an opening 237 , a middle section 238 a first end section 239a and a second end portion 239b educated.

The male screen contact ring 230 is analogous to the female shield contact ring 130 designed and intended, in the assembled state with the male screw ring 260 rotatably connected to be. For this purpose, the male umbrella contact ring 230 at the middle section 238 a fastener 234 which, in the mounted state in the fastening engagement 265 of the male screw ring 260 (please refer 8A) intervenes. Further, the male shield contact ring at the first end portion 239a a first male spring element 232 for electrically contacting the male screen element 270 and at the second end portion 239b a male inhibitor 236 to the Inhibiting a twisting movement of the male screw ring 260 (in 12a not shown).
