Description

Contact insert for a stationary pole and contact insert assembly

Technical Field

The invention relates to a contact insert for a stationary pole of a plug connector, comprising a contact insert body and a plurality of contact elements arranged in the contact insert body. The invention further relates to a contact insert assembly for a plug connector, comprising a contact insert of a stationary pole, wherein the contact insert of the stationary pole comprises a contact insert body and a plurality of contact elements arranged in the contact insert body.

Background

A plurality of contact inserts for plug connectors are known from the prior art, in which a plurality of contact elements are arranged. The contact insert is usually arranged in a housing part of the plug connector, which is designed to accommodate the contact insert. For this purpose, the contact insert body is usually connected to a housing part of the plug connector. The contact inserts are used for connecting with corresponding counterpart contact inserts, which are arranged in the housing of the counterpart plug connector.

The contact elements arranged in the contact insert body can be configured, for example, as contact pins or contact receptacles, which are connected to corresponding contact elements of the mating contact insert when the contact insert is plugged together with the corresponding mating contact insert or the plug connector is plugged together with the corresponding mating plug connector. By plugging together, the contact elements are commonly contacted. In the plug connectors known from the prior art, the contact elements arranged in the contact insert body are formed in the same way with respect to the contact region and the connection region in order to ensure uniform contact.

In principle, the contact inserts can be divided into modular contact inserts and fixed-pole contact inserts. The modular contact insert is usually first inserted into a holding frame, which is then inserted into a housing part of the plug connector and secured therein. Since the contact inserts can be individually inserted into the holding frame, there is the possibility that the holding frame is equipped with different contact inserts depending on the purpose of use.

In contrast, the contact inserts of the stationary poles are inserted directly, i.e. without the use of a holding frame, into the housing part of the plug connector and are fixed therein. Such a contact insert has a contact insert body in which a plurality of contact elements are arranged. In the contact insert of the stationary pole, the number of contact elements arranged in the contact insert body cannot be changed. The invention relates to a contact insert for a stationary pole which is inserted directly into and fixed in a housing part of a plug connector without the use of a retaining frame.

In general, the contact insert, i.e. in particular also the contact insert thus comprising the stationary pole in question, mostly has at least one protective conductor and/or a ground connection terminal in addition to the contact element arranged in the contact insert body. Thus, when in the contact insert of the stationary pole according to the invention it is said that the contact insert of the stationary pole has contact elements arranged in the contact insert body, then the at least one protection conductor and/or the ground connection does not fall within the scope of these contact elements, but can be regarded as being separated from these contact elements. The above-mentioned holding frame of the modular contact insert also generally has at least one protective conductor and/or an earth connection. Such a holding frame for a modular contact insert differs significantly from the contact insert of the stationary pole, which has, in addition to at least one protective conductor and/or a ground connection, further contact elements arranged in the contact insert body.

Different types of contact inserts for stationary poles are known from the prior art. The contact inserts of these fixed poles can differ in particular with regard to the type and number of contact elements arranged in the contact insert body, but also with regard to their arrangement. However, it is common to all fixed-pole contact inserts that the use of fixed-pole contact inserts is limited by the contact elements fixedly integrated in the contact insert body and inflexible.

Disclosure of Invention

It is therefore an object of the present invention to provide a pole-fixed contact insert which can be used in a range of applications which is extended with respect to conventional pole-fixed contact inserts. Furthermore, the invention is based on the object of providing a contact insert assembly which can be flexibly designed for different fields of use.

This object is achieved in the contact insert according to the invention with the features of claim 1 in that the contact insert body has at least one first receiving position for receiving at least one modular contact insert. According to the invention, it has been recognized that the range of use of the contact insert of the stationary pole can be considerably expanded if the contact insert body has at least one receiving position for receiving at least one modular contact insert. The contact insert of the stationary pole according to the invention can be provided with at least one, in particular a plurality of modular contact inserts. In this way, it is possible to expand the contact insert of the stationary pole with additional contact elements, i.e. with contact elements of the modular contact insert, in a particularly flexible manner. In particular, the contact insert of the stationary pole according to the invention can be adapted simply to different application areas and can therefore be used in a versatile and flexible manner. The contact insert according to the invention furthermore enables a flexible combination of different types of contact inserts with one another in a particularly flexible manner and with a method, in particular by means of the contact inserts being embodied as modular types of contact elements in terms of type and/or arrangement, being able to be inserted into at least one first receiving position. In order to achieve a simple accommodation of the modular contact insert, the preferred design of the contact insert according to the invention is characterized in that at least one accommodation site has a holding frame for accommodating at least one modular contact insert. In a first variant, the holding frame is constructed as a separate component. Then, the holding frame is arranged in the accommodation position and connected to the contact insert body. The connection between the holding frame and the contact insert body can be realized, for example, by a screw connection or a snap-lock connection.

In order to fix the at least one modular contact insert in the holding frame, the holding frame has, in a preferred embodiment, at least one spring element which is designed for fixing the modular contact insert. Preferably, the spring element is at least temporarily transferred to the pretensioned state when the modular contact insert is inserted. If the modular contact insert is arranged in its final position in the receiving position, the at least one spring element is preferably in a state in which the pretension is at least reduced relative to the state in which the maximum pretension is reached. Particularly preferably, the at least one spring element is then in a relaxed state.

In order to fix the at least one modular contact insert in the holding frame, the spring element preferably has at least one latching element. The latching element is preferably designed as a latching nose or a latching projection. The modular contact insert provided for accommodation into the accommodation position then preferably has a latching recess into which at least one latching element engages in the inserted state of the modular contact insert.

Particularly preferably, the holding frame has at least one second spring element for fixing the modular contact insert. Particularly preferably, the holding frame has at least one first end side and a second end side opposite the first end side and a first longitudinal side and a second longitudinal side opposite the first longitudinal side, and furthermore the two spring elements are arranged on opposite sides of the holding frame, i.e. on opposite end sides or on opposite longitudinal sides.

The embodiment with a holding frame which is constructed as a separate component and is connected to the contact insert body has the advantage that different types of holding frames can be inserted into the contact insert body. Furthermore, the holding frame is exchangeable, so that, for example, in the event of damage to the holding frame, only the holding frame can be exchanged.

In order to reduce the effort required for mounting the holding frame in the receiving position, the holding frame is at least partially formed in the contact insert body in a particularly preferred embodiment of the contact insert of the stationary pole according to the invention. The holding frame is thus at least partially formed integrally with the contact insert body, i.e. is molded in the contact insert body in the region of the receiving location.

Particularly preferably, the holding frame configured in the receiving position has at least one spring element for fixing the at least one modular contact insert in the receiving position. Particularly preferably, the at least one spring element is formed integrally with the contact insert body. Preferably, the spring element is at least temporarily transferred to the pretensioned state during the insertion of the modular contact insert. If the modular contact insert is arranged in its final position in the receiving position, the at least one spring element is preferably in a state in which the pretension is at least reduced relative to the state in which the maximum pretension is reached. Particularly preferably, the at least one spring element is then in a relaxed state.

In order to fix the at least one modular contact insert in the holding frame configured in the receiving position, the spring element preferably has at least one latching element, particularly preferably a latching nose or a latching projection. The modular contact insert then preferably has a latching recess into which at least one latching element engages in the inserted state of the modular contact insert.

In a particularly advantageous embodiment, which further reduces the installation effort, the retaining frame is formed entirely in the contact insert body. Thus, no additional separate fastening means are required for fastening the modular contact insert.

In one embodiment, the holding frame formed in the contact insert body in the region of the receiving location has at least one second spring element for fixing the modular contact insert. Particularly preferably, the holding frame has at least one first end side and a second end side opposite the first end side and a first longitudinal side and a second longitudinal side opposite the first longitudinal side, and furthermore the two spring elements are formed on opposite sides of the holding frame, i.e. on opposite end sides or on opposite longitudinal sides.

The contact insert body of the contact insert of the stationary pole can be realized differently according to the invention. In a first variant, the contact insert body is made of an electrically insulating material. It is particularly preferred that the contact insert body is made of plastic. This can be produced, for example, by means of an injection molding method. The use of an electrically insulating material for the contact insert body has the advantage that the contact elements of the contact insert body are electrically insulated from one another and also ensure electrical insulation with respect to the modular contact insert which can be accommodated in the accommodation position. If the contact insert has a protective conductor terminal and/or a ground terminal, in a particularly preferred embodiment at least one electrical connection element is arranged between the protective conductor terminal and/or the ground terminal and the receiving position for electrically contacting the modular contact insert which can be received in the receiving position. If the modular contact insert is arranged in the receiving position, the modular contact insert is contacted by the electrical contact element.

In an alternative configuration, the contact insert body is made of an electrically conductive material. It is particularly preferred that the contact insert body is made of metal. The electrical connection between the modular contact insert which can be accommodated in the accommodation position and the protective conductor and/or the ground contact of the contact insert takes place via the electrically conductive contact insert body.

In a further embodiment, the contact insert body is made at least in part of an electrically insulating material (for example plastic) and an electrically conductive material (for example metal).

In order to arrange the receiving position for at least one modular contact insert in the contact insert body, different embodiments exist according to the invention. Particularly preferably, the contact elements of the contact inserts of the stationary poles are arranged at least partially in the contact element region. It is further preferred that the contact element region of the contact insert of the stationary pole has a contact element region longitudinal axis. In the case of the contact inserts of the stationary poles known in practice, the contact element region longitudinal axis is generally parallel to the longitudinal sides of the contact insert or the contact element region longitudinal axis is parallel to the end sides of the contact insert.

According to the invention, the at least one receiving location has a receiving location longitudinal axis. The receiving position is preferably dimensioned such that it has a greater extent in the direction of the longitudinal axis of the receiving position than in a direction perpendicular to the longitudinal axis of the receiving position. In one embodiment, the extension of the receiving location in the direction of the longitudinal axis of the receiving location corresponds to the extension of the receiving location in a direction perpendicular to the longitudinal axis of the receiving location. The receiving position is then essentially square. According to the invention, in one variant, it is now provided that the contact element region longitudinal axis and the receiving position longitudinal axis extend parallel to one another. In an alternative variant, it is provided that the contact-area longitudinal axis and the accommodation-position longitudinal axis extend perpendicularly to one another.

By virtue of the inventive orientation of the receiving position relative to the contact elements or at least some of the contact elements arranged in the contact insert body, a space-saving and clear assembly of the contact insert of the stationary pole with at least one modular contact insert can be achieved.

It is particularly preferred that the contact insert body has two opposite end sides and two opposite longitudinal sides. Further preferably, the at least one receiving location is formed on one end face of the contact insert body. Particularly preferably, the accommodation longitudinal axis is parallel to an end-side plane which is spanned by at least one end side. In a further embodiment, the accommodation longitudinal axis is perpendicular to an end-side plane which is spanned by at least one end side.

In an alternative embodiment, at least one receiving location is configured on one longitudinal side of the contact insert body. Particularly preferably, the accommodation longitudinal axis is parallel to a longitudinal side plane spanned by the at least one longitudinal side. In a further embodiment, the accommodation longitudinal axis is perpendicular to a longitudinal side plane spanned by the at least one longitudinal side.

In a further preferred embodiment, the contact elements of the contact inserts of the stationary poles are arranged in at least two contact element regions. It is further preferred that the contact element regions of the contact inserts of the stationary poles each have a contact element region longitudinal axis. It is further preferred that the first contact element region longitudinal axis is oriented parallel to the second contact element region longitudinal axis or perpendicular to the second contact element region longitudinal axis. The contact elements in the first contact element region are configured identically or differently to the contact elements in the second contact element region.

Particularly preferably, at least one receiving position for the modular contact insert is formed between the first contact element region and the second contact element region.

In the embodiment described so far, the receiving position is designed to receive at least one modular contact insert. In a particularly preferred variant of the contact insert of the stationary pole according to the invention, at least one first receiving position is provided for receiving a plurality of modular contact inserts. Particularly preferably, a plurality of modular contact inserts can be arranged directly adjacent to one another in the receiving position. It is further preferred that the plurality of modular contact inserts can be fixed in the receiving position independently of one another, for example by means of the spring elements described above, so that the plurality of modular contact inserts can be inserted into the receiving position or removed from the receiving position separately.

A particularly preferred embodiment of the contact insert of the stationary pole according to the invention, which further improves the modularity of the contact insert, is characterized in that the contact insert body has at least one second receiving position for receiving at least one further modular contact insert. In the case of a contact insert of a stationary pole, at least two modular contact inserts can therefore be inserted into different receiving positions. Particularly preferably, at least the second receiving position is configured according to at least one of the designs previously implemented in connection with the first receiving position.

The first receiving position and the second receiving position are configured identically in one embodiment. In a further embodiment, the first receiving position and the second receiving position are designed differently. If the first and second receiving locations are designed differently, in one variant, the two receiving locations are designed to receive different types of modular contact inserts.

The first receiving position preferably has a first receiving position longitudinal axis, and the second receiving position preferably has a second receiving position longitudinal axis. In a completely special embodiment, the first accommodation longitudinal axis and the second accommodation longitudinal axis extend parallel to one another. In one variant, the first accommodation longitudinal axis and the second accommodation longitudinal axis are identical, so that the first accommodation and the second accommodation are arranged along a common accommodation longitudinal axis.

In an alternative variant, the first accommodation longitudinal axis and the second accommodation longitudinal axis are perpendicular to one another.

If the contact insert body has a first end side and a second end side opposite the first end side, and a first longitudinal side and a second longitudinal side opposite the first longitudinal side, in a particularly preferred embodiment the first receiving position is configured on the first end side and the second receiving position is configured on the second end side. In an alternative variant, both the first receiving position and the second receiving position are formed on the first end face. The accommodation longitudinal axis may then be parallel to an end-side plane which is spread out by the first end side or perpendicular to an end-side plane which is spread out by the first end side, for example.

In a further variant, the first receiving position and the second receiving position are embodied on a first longitudinal side of the contact insert body. Particularly preferably, the accommodation longitudinal axis is then parallel to the longitudinal side plane spanned by the first longitudinal side or parallel to the longitudinal side plane spanned by the first longitudinal side. In a further embodiment, it is provided that the first receiving position is formed on the first longitudinal side and the second receiving position is formed on the second longitudinal side.

In a further alternative, the first receiving position is configured at one end side and the second receiving position is configured at one longitudinal side.

In addition to the contact insert of the stationary pole, the invention likewise relates to a contact insert assembly for a plug connector. The contact insert assembly has a fixed pole contact insert having a contact insert body and a plurality of contact elements disposed within the contact insert body. In the contact insert assembly according to the invention, the object of the invention is achieved in that the contact insert body has at least one first receiving position for receiving at least one modular contact insert, and in that the at least one modular contact insert is arranged in the receiving position of the contact insert body of the contact insert of the stationary pole.

A particularly preferred embodiment of the contact insert assembly according to the invention is characterized in that the contact insert of the stationary pole is realized in at least one of the embodiments described previously in connection with the contact insert of the stationary pole according to the invention. Accordingly, all the previously described embodiments, together with their advantages with respect to the realization of the contact insert of the stationary pole according to the invention, can be transferred to and correspondingly applied to the contact insert assembly according to the invention.

The modular contact insert of the contact insert assembly according to the invention can be constructed in a manner known from the prior art. Accordingly, the modular contact insert of the contact insert assembly according to the invention can be realized, for example, as a single module, as a double module or as a half module or in other known ways.

A special design of the contact insert assembly according to the invention is characterized in that at least one second modular contact insert is provided. In one variant, at least the second modular contact insert is likewise arranged in at least one first receiving position, in an alternative variant in which the contact insert body has at least one second receiving position, at least the second modular contact insert is arranged in the second receiving position.

In one variant, the at least first modular contact insert and the at least second modular contact insert are identically designed. In an alternative variant, the first modular contact insert and the second modular contact insert are designed differently from one another.

Detailed Description

Fig. 1 shows a view of a contact insert 1 for a stationary pole of a plug connector, not shown. The contact insert 1 of the stationary pole has a contact insert body 2 in which a plurality of contact elements 3 are arranged. The contact element 3 is designed here as a contact socket 4. The pole-fixed contact insert 1 has a receiving location 5 for receiving a modular contact insert 6. In order to be able to arrange and fix the modular contact insert 6 in the receiving position 5 in a particularly advantageous manner, the receiving position 5 has a holding frame 7 for receiving the modular contact insert 6.

Fig. 2 shows an embodiment in which the holding frame 7 is formed as a separate component 8. In the embodiment shown, the holding frame 7 embodied as a separate component 8 is connected to the contact insert body 2 by means of an additional connecting element 9 in the receiving position 5. For this purpose, a total of four connecting elements 9 are provided, which fix the holding frame 7. The holding frames 7, 8 have two spring elements 10 for fixing the modular contact inserts 6. The spring element 10 is arranged on the end sides 11, 12 of the receiving location 5 or the holding frame 7, 8 opposite one another.

Unlike the embodiment shown in fig. 2, in the embodiment shown in fig. 1 the holding frame 7 is constructed in the contact insert body 2, i.e. is formed by the contact insert body 2. The holding frame 7 likewise has two spring elements 10 for fixing the modular contact insert 6, which are each formed integrally with the contact insert body 2. For fixing the modular contact insert 6, the spring element 10 has latching elements 13 which engage in corresponding latching recesses formed on the modular contact insert 6.

The contact insert body 2 of the contact insert 1 of the stationary pole shown in fig. 1 is made of an electrically insulating material, i.e. of plastic. The contact insert 1 furthermore has a protective conductor connection 14 which is electrically connected to the receiving location 5 by means of at least one electrical connection element, in order to be able to establish an electrical connection with a modular contact insert which can be received in the receiving location 5.

The contact insert body 2 of the contact insert of the stationary pole shown in fig. 2 is made of an electrically conductive material, i.e. currently made of metal. The electrical connection between the protective conductor terminal 14 and the modular contact insert 6 arranged in the receiving position 5 then takes place via the electrically conductive contact insert body 2. The contact element 3 is embodied as a contact pin 15 in the illustration of fig. 2.

The contact element 3 is arranged in the contact element region 16. The contact element region 16 has a contact element region longitudinal axis 17.

In the configuration shown in fig. 2, the receiving location 5 is configured on the first end side 19 of the contact insert body 2. The receiving location 5 is furthermore realized such that the receiving location longitudinal axis 18 extends parallel to an end-side plane 23 which is open by the first end side 19. The end plane 23 is perpendicular to the paper plane in fig. 2. In the embodiment shown in fig. 3, the receiving location 5 is formed on the second longitudinal side 22 of the contact insert body 2. The receiving position 5 is furthermore realized in such a way that the receiving position longitudinal axis 18 extends parallel to a longitudinal side plane 24 which is extended by the second longitudinal side 22. The longitudinal side plane 24 is perpendicular to the paper plane in fig. 3.

In fig. 4, the receiving location 5 is designed to receive two modular contact inserts 6. In the region of the receiving location 5, a holding frame 7 is formed in the contact insert body 2, which holding frame 7 is designed to receive two modular contact inserts 6. In the exemplary embodiment shown, the holding frame 7 has four spring elements 10, two spring elements 10 being used for holding a modular contact insert 6. The two modular contact inserts 6, 6' are configured differently. As a result, different modular contact inserts can be easily arranged in the receiving location 5, whereby the contact insert assembly 27 can be flexibly designed.

Fig. 5 shows a view of a contact insert 1 of a fixed pole, which has, in addition to a first receiving location 5 for receiving a modular contact insert 6, a second receiving location 25 for receiving another modular contact insert 6'. The second receiving position 25 has a second receiving position longitudinal axis 26 which extends parallel to the receiving position longitudinal axis 18 of the first receiving position 25. The first receiving location 5 is formed on the first end side 19 of the contact insert body 2, while the second receiving location 25 is formed on the second end side 20 of the contact insert body 2.

The contact insert 1 of the stationary pole shown in fig. 6 also has two receiving locations 5, 25 for receiving at least two modular contact inserts 6, 6'. Unlike the embodiment shown in fig. 5, the accommodation longitudinal axes 18, 26 of the two accommodation positions 5, 25 are parallel to one another, i.e. coincide in this embodiment. Furthermore, two receiving locations 5, 25 are provided on the second longitudinal side 22 of the contact insert body 2.

The contact insert 1 of the stationary pole has a contact insert body 2 and a plurality of contact elements 3 arranged in the contact insert body 2. Furthermore, the contact insert body 2 has a first receiving position 5 for receiving at least one modular contact insert 6, the modular contact insert 6 being arranged in the receiving position 5 of the contact insert body 2. In the embodiment shown in fig. 7, the modular contact insert 6 is arranged in the receiving position 5, and in the embodiment shown in fig. 6, two modular contact inserts 6, 6' are arranged in the receiving position 5. The two modular contact inserts 6, 6' are identically formed.

The pole-fixed contact insert 1 has a receiving location 5, which receiving location 5 is designed to receive two modular contact inserts 6, 6'. For this purpose, the receiving location 5 has a holding frame 7 which is formed in the contact insert body 2 and has a total of four spring elements 10. In contrast to the embodiment shown in fig. 4, the holding frame 7 is configured in the receiving position 5 rotated by 90 °. The receiving position longitudinal axis 18 and the contact element region longitudinal axis 19 are parallel to one another, i.e. in particular coincide, in the illustrated embodiment. In fig. 8, furthermore, the electrical connection element 28 for establishing an electrical connection between the protective conductor connection and the modular contact elements 6, 6' which can be arranged in the receiving position 5 is embodied in the form of a contact frame.

Fig. 9 shows an alternative embodiment of the contact insert 1 of the stationary pole. The contact insert 1 of the stationary pole shown here has a first receiving position 5 for receiving a first modular contact insert 6 and a second receiving position 25 for receiving a second modular contact insert 6'. The first receiving location 5 and the second receiving location 25 are configured differently from one another and serve to receive modular contact inserts 6, 6' that differ from one another. In the illustration, the second modular contact insert 6' is arranged in the second receiving position 25, whereas the modular contact insert 6 is not arranged in the first receiving position 5. The receiving location 25 has a circular cross section and receives a modular contact insert 6' which likewise has a circular cross section. The first receiving location 5 has a rectangular cross section unlike the second receiving location 25. The first receiving location 5 is formed on the second end 20 of the contact insert 1 of the stationary pole, and the second receiving location 25 is formed on the first end 19 of the contact insert 1 of the stationary pole. The contact elements 3 arranged in the contact insert body 2 are arranged in a contact element region 16 which is formed centrally between the first receiving position 5 and the second receiving position 25.

Fig. 10 shows a contact insert 1 of a fixed pole, which has a receiving position 5 in the middle of the contact insert body 2. The contact insert 1 of the stationary pole has a second contact element region 29 in addition to the first contact element region 16.
