The present invention relates to a connector having a receptacle and a plug which are electrically connected to each other, and which can be reliably maintained in the locked state of the receptacle and the plug by the action of the receptacle side anchor provided on the receptacle and the plug side anchor provided on the plug. will be.

In a connector having a receptacle and a plug, and inserting a plug into an insertion groove provided in the receptacle, the connector is connected to each other. As the size of a portable terminal or other device mounting the plug is reduced, the demand for low magnification is increasing.

However, when the connector is made low, the contact pressure of the receptacle contact and the plug contact tends to decrease because the stroke of the receptacle contact and the plug contact in the insertion / removal (insertion and release) direction of the plug is reduced. Also, the smaller the number of contacts, the more difficult it is to keep the plug and receptacle locked.

On the other hand, a connector has been proposed in which receptacle-side anchors are mounted at both ends in the longitudinal direction of the receptacle, and plug-side anchors are mounted at both ends in the longitudinal direction of the plug (Japanese Patent Laid-Open No. 2003-297485 and Japanese Patent Laid-Open No. 2001-57273). report). These connectors are fitted with the locking portion provided on the receptacle side anchor and the locked portion provided on the plug side anchor to achieve a more secure locking state than before.

However, in the above-described connector, since the receptacle side anchor and the plug side anchor are formed by shearing, if the plug is repeatedly inserted and detached, the shearing surface is not likely to damage the mating member or the peripheral member. This causes a problem that foreign matter is generated and accumulated in the connector. In addition, the receptacle-side anchor and the plug-side anchor were difficult to cope with continued low magnification of the connector due to its structure.

Moreover, a predetermined space | interval is formed between the receptacle and a plug for the fitting, and the fitting position of a receptacle and a plug may shift | deviate within the range of this space | interval. Depending on the degree of this misalignment, the receptacle-side anchor and the plug-side anchor are not accurately engaged, and thus a direction in which the locking force decreases is generated. Therefore, when a vibration or an impact is applied, the plug is easily released from the receptacle in that direction.

The plug 50 shown in Fig. 3 is formed of a substantially rectangular parallelepiped plug body 60 made of an insert molded article of synthetic resin, which is an insulating member, and a strip-shaped metal member, respectively, in the longitudinal direction of the plug body 60. In each of the plurality of plug contacts 70 provided at the same pitch in correspondence with the receptacle contacts 30 in the receptacle 10 and the wall portions 64 provided at both ends of the plug body 60 in the longitudinal direction, respectively. It is provided with the plug side anchor 80 assembled. The plug body 60 is made of, for example, nylon 9T (trade name), modified nylon, and a liquid crystal polymer, and is an insulating member formed by integrally molding (insert molding) together with the plug contact 70.

The plug contact 70 is installed to penetrate the longitudinal wall portion 61 of the plug body 60, and the plug side terminal portion 74 extending outward from the longitudinal wall portion 61 is an installation object (e.g., a circuit Soldered to the conductive pattern of the substrate). In addition, the plug side anchor 80 has its plug side fixing parts 88 and 89 electrically or mechanically connected to the installation object, respectively.

The plug-side anchor 80 shown in FIG. 4 includes a base portion 82 formed of an elongated plate member, an insertion portion 83 extending from a widthwise end portion in the longitudinal center of the base portion 82, and an insertion portion ( 83 from each of a pair of engagement retaining portions 84, 85 provided on both sides in the longitudinal direction of the base 82, and both ends 86, 87 of the base 82 bent perpendicularly to the longitudinal direction.

By inserting the engagement retaining portions 84 and 85 into the engagement holes 64a and 64b respectively drilled in the wall portion 64, the plug side anchor 80 is retained in the plug body 60. As shown in FIG. In addition, the plug side fixing parts 88 and 89 may be provided in parallel in the direction crossing the longitudinal direction of the base 82, and may be provided in arbitrary positions of the base 82 other than the both ends 86 and 87. FIG. . In addition, as long as the engagement holding | maintenance parts 84 and 85 correspond with the engagement holes 64a and 64b, it can install in arbitrary numbers in arbitrary places.

The insertion portion 83 is formed by bending a plate-shaped member having a constant plate thickness by rolling, and is formed from a vertical portion 83a extending in parallel with the base 82 and a longitudinal center of the base 82. It consists of the bending part 83b connected to the edge part of the perpendicular | vertical part 83a by folding and folding the plate-shaped member extended in the width direction. The insertion portion 83 is substantially U-shaped and bent at predetermined intervals G together with the base 82 (FIG. 4C). In the vertical portion 83a, a pair of projections 83a1 protruding in a direction away from the base 82 are formed at a predetermined position in the longitudinal direction (direction parallel to the width direction of the base 82). In addition, instead of the projection part 83a1, you may make it dimple shape and bead shape. In addition to being provided at the center of the longitudinal direction of the base 82 in addition, the insertion part 83 may be provided one by one in the position which is symmetrical with respect to the longitudinal center of the base 82. In addition, the vertical portion 83a and the bending portion 83b, and the bending portion 83b and the base portion 82 may be folded at right angles, respectively, to form a 'c' shape. The insertion portion 83 can be formed by setting the distance between the vertical portion 83a and the base 82 to zero or extending the width from the central portion of the base 82 in the width direction without performing bending. In view of the followability of inserting and removing the plug 50, it is preferable that there is a gap G between the vertical portion 83a and the base 82 in that elasticity of the vertical portion 83a can be obtained. .

The plug side anchor 80 is inserted into the wall portion 64 from the fitting direction upward (bottom of FIG. 3) of the plug 50 and mounted to the plug body 60. The base 82 is in contact with the inner wall 64d, and the bent portion 83b is in contact with the inner wall 64c, respectively. In the longitudinal direction of the plug 50, the distance D2 from the end face 64e of the wall portion 64 to the outer side surface 83a2 of the vertical portion 83a (base portion 82 in the longitudinal direction of the plug 50). The plate thickness of the end face 64e is added to the distance D4 from the outer side surface 82a of the side surface 82a to the outer side surface 83a2 of the vertical part 83a), and is set larger than D1 and smaller than D3.

The receptacle side anchor 40 and the plug side anchor 80 are formed on a base material (for example, beryllium copper, titanium copper, and corson (nickel-silicon) copper alloy) stamped and molded into a predetermined shape. ) Plating (for example, nickel plating) is performed, and finish plating (for example, tin-copper plating, tin-zinc plating, and gold plating) is performed. The plate thickness of the receptacle side anchor 40 and the plug side anchor 80 is preferably 0.08 to 0.15 mm from the viewpoint of spring design and workability, while minimizing and reducing the size of the connector. It is preferable that the thickness of the base plating at this time is 0.5 micrometer-4 micrometers. This is because if the thickness is less than 0.5 µm, the effect of the underlying plating cannot be obtained. If the thickness exceeds 4 µm, the cost increases, and cracks tend to occur due to deformation during sliding bonding with the plug 50. Moreover, it is preferable that the thickness of finish plating is 1-10 micrometers. This is because the effect as a finish plating cannot be acquired when it is less than 1 micrometer, and cost increases when it exceeds 10 micrometers. In particular, when finish plating is gold plating, 0.03-0.2 micrometer is preferable. This is because the effect as a finish plating cannot be acquired when it is less than 0.03 micrometer, and cost increases when it exceeds 0.2 micrometer.

According to the above configuration, when the plug 50 is fitted to the receptacle 10, the plug contact 70 is fitted into the receptacle contact 30, and the insertion portion 83 of the plug-side anchor 80 is attached to the wall portion ( The plug side anchor 80 is retained in the receptacle side anchor 40 by fitting into the recess 43b together with 64. As a result, while the plug 50 and the receptacle 10 are locked, the plug side anchor 80 and the receptacle side anchor 40 are connected to each other (FIG. 5). Since the distance D2 from the end face 64e of the wall portion 64 to the outer surface 83a2 of the vertical portion 83a is set larger than D1, the insertion portion 83 and the wall portion 64 are recessed portions. It is hold | maintained reliably by the elastic force of 43b. In addition, since D2 is smaller than D3, the second protrusion 43b2 reliably secures the plug 50 even when the plug 50 is elastically deformed to open when the plug 50 is fitted to the receptacle 10. ), It is possible to prevent the plug 50 from easily coming off.

Furthermore, by providing the first projection 43b1 and the second projection 43b2 projecting inwardly in the opening portion of the substantially U-shaped recess 43b, the projection 83a1 is provided in the vertical portion 83a. When fitting the insertion portion 83 into the recess 43b, the protrusion 83a1 passes over the first protrusion 43b1 and the second protrusion 43b2. For this reason, a click feeling can be obtained when inserting the insertion part 83 into the recessed part 43b, and after fitting, the insertion part 83 is prevented from easily coming out of the recessed part 43b, and the plug 50 is prevented. ) And the receptacle 10 can be firmly locked.

In addition, since the rolling surfaces of the elastic retaining portion 43 and the insertion portion 83 are slidably moved to each other so that the insertion portion 83 is inserted into the recess 43b, the plug 50 is repeatedly inserted and inserted. Even if it does, damage to the elastic retaining part 43, the insertion part 83, and the member around it is little. Therefore, a connector with high durability against being plugged in and out can be realized.

In addition, even when the fitting position of the plug 50 is shifted with respect to the receptacle 10 or the plug 50 is fitted in a twisted state, the elastic retaining portion 43 can easily follow the shape and elasticity. As a result, a certain locking state can be realized by a constant holding force.

In addition, in the example shown in FIG. 5, although the wall part 64 and the insertion part 83 were inserted in the recessed part 43b, it can also be set as the structure which only inserts the insertion part 83 as shown in FIG. In this case, the distance D1 between the first protrusion 43b1 and the second protrusion 43b2 and the outside of the vertical portion 83a from the outer surface 82a of the base 82 in the longitudinal direction of the plug 50. The relationship between the distance D4 to the side surface 83a2 and the distance D3 from the connecting portion 42 to the furthest part among the inner surfaces of the first protrusion 43b1 and the second recess 145 is D3> D4. It is preferable to become> D1. This relationship is compared with the example shown in FIG. 5 so as to narrow the interval between the first standing portion 143 and the second standing portion 145 and the first protrusion 43b1 and the second protrusion 43b2. The elastic holding part 43 can be processed so that the space | interval can be reduced, and / or the board thickness of the insertion part 83 of the plug side anchor 80 can be made thick. By such a configuration, the insertion portion 83 is reliably retained by the elastic force of the recess portion 43b, and elastically so that the recess portion 43b is opened when the plug 50 is fitted to the receptacle 10. In spite of the deformation, the second projection 43b2 can reliably contact the plug 50, so that the plug 50 can be easily prevented from coming off.

When the fitted plug 50 is disengaged from the receptacle 10, when the left and right anchors are pulled out at different timings (tilt extraction), the engaging portion 43c of the receptacle side anchor 40 is with the plug 50. In order to prevent being easily lifted up, the configuration of (1) to (5) below is useful.

(1) As shown in Fig. 7, the engaging portion 143a extending outward in the horizontal direction is provided at approximately the center in the vertical direction of the first standing portion 143, and at the position corresponding thereto of the receptacle body 20. The recessed part (not shown) is provided, and when the receptacle side anchor 40 is assembled to the receptacle main body 20, the engaging part 143a fits into a recessed part. As a result, the engagement portion 143a maintains the state in which the engagement portion 143a is fitted into the recessed portion even when the plug 50 is detached, thereby preventing the engagement portion 43c from being lifted up.

In addition, by inserting the engaging portion 143a into the receptacle body 20 without providing a recess in the receptacle body 20, the first standing portion 143 is fixed to prevent the engaging portion 43c from being lifted up. You may.

(2) As shown in FIG. 8, the engaging part 43c2 extended horizontally outward in the substantially perpendicular direction of the front-end | tip part 43c1 (refer FIG. 9) extended in a perpendicular direction among the engaging parts 43c. And a recess (not shown) is provided at a position corresponding to that of the receptacle main body 20, and the engaging portion 43c2 is recessed when the receptacle side anchor 40 is assembled to the receptacle main body 20. It is set as the structure fitted to a part. Thereby, even when the plug 50 is disengaged, since the engagement part 43c2 keeps being fitted in the recessed part, the engagement part 43c can be prevented from lifting up.

In addition, by inserting the engaging portion 43c2 into the receptacle body 20 without providing a recess in the receptacle body 20, the tip portion 43c1 is fixed to prevent the engaging portion 43c from being lifted up. have.

(3) As shown in FIG. 9, the front end piece 43c3 of the front end part 43c1 of the engaging part 43c is bent away from the 2nd standing part 145, and the receptacle main body 20 of When the recessed part 25 is provided in the corresponding part of the to-be-engaged part 24, and the receptacle side anchor 40 is assembled to the receptacle main body 20, the front-end piece 43c3 is fitted into the recessed part 25, It is assumed that it enters. Thereby, since the front end piece 43c3 is restricted from moving upward by the recessed part 25, the engaging part 43c can be prevented from lifting up when the plug 50 is disengaged.

(4) As shown in FIG. 9, when the receptacle side anchor 40 is assembled to the receptacle main body 20, the convex portion 26 protruding upward from the distal end portion 43c1 side of the engaging portion 43c. It is formed in the receptacle body 20. As a result, the engaging portion 43c comes into contact with the convex portion, whereby the engaging portion 43c can be prevented from being lifted up when the plug 50 is detached.

(5) As shown in FIG. 10, when the plug 50 is fitted to the receptacle 10 in the wall portion 64, the bottom portion 144 is positioned to be in contact with the second protrusion 43b2 or to be in contact with the second protrusion 43b2. The inclined surface 64e1 is provided on the wall portion 64 so that the distance between the elastic retaining portion 43 and the end face 64e is widened from the position of to the bottom portion 144 side. This inclined surface 64e1 may be flat or curved. As a result, even if the plug 50 is pulled out obliquely from the fitted state to the receptacle 10, the interference between the second protrusion 43b2 and the wall portion 64 can be reduced, and the receptacle side anchor 40 is receptacle ( 10) can be prevented.

In addition, if the shape accuracy of the insertion portion 83 or the projection 83a1 of the plug-side anchor 80 is low, the fitting of the receptacle-side anchor 40 and the plug-side anchor 80 becomes incomplete or sufficient locking force is achieved. There is a case that can not be obtained. In such a case, the configuration of (6) and (7) below is effective.

(6) As shown in FIG. 11, when the plug 50 is fitted to the receptacle 10, the base portion 83b is opposed to the bottom portion 144 without the wall portion 64 interposed therebetween. The length L1 from 82 to the bent portion 83b and the length L2 from the bent portion 83b to the tip of the vertical portion 83a are increased, and among the wall portions 64 of the plug body 60, It is substantially parallel with the bottom part 144, and the front-end | tip part arrange | positioned between the bending part 83b and the bottom part 144 is removed.

(7) As shown in FIG. 11, the position of the projection part 83a1 in the insertion direction of the plug side anchor 80 is shifted to the bottom part 144 side. That is, when the plug 50 is fitted to the receptacle 10, a contact margin L4 is formed between the first protrusion 43b1 and the protrusion 83a1 in the insertion direction of the plug 50.

According to such a configuration (6) and (7), since the insertion part 83 of the plug-side anchor 80 can be enlarged even if the connector is made low, for example, it can shape | mold more precisely. . In addition, even if there is a difference in the distance (stacking) between the substrate on which the plug 50 is mounted and the substrate on which the receptacle 10 is mounted or the angle of these substrates, a stable contact resistance can always be obtained by providing a contact margin. have. Furthermore, by providing a contact margin, when fitting the plug side anchor 80, the projection part 83a1 will necessarily pass over the 1st projection part 43b1, and a stable locking force can be obtained. In addition, since the concave portion 43b of the elastic retaining portion 43 and the vertical portion 83a of the insertion portion 83 can be electrically connected to each other reliably by such a configuration, the receptacle side anchor 40 And the plug side anchor 80 can be used as a conductive member (for example, for ground connection).

In addition, as shown in FIG. 12, the edge part (dotted line part of FIG. 12) arrange | positioned at the board | substrate surface side (side in which the elastic retaining part 43 is not provided in the width direction of the connection part 42) among the connection parts 42 is shown. If removed, the connection part 42 can be dropped from the board | substrate which mounts the receptacle side anchor 40. FIG. In addition, as shown in FIG. 13, the edge part arrange | positioned at the board | substrate surface side (side in which the insertion part 83 is not provided in the width direction of the base part 82) in the base part 82, and the vertical part of the insertion part 83 is shown. If the tip portion (and the dotted line portion 13) of 83a is deleted, the base portion 82 and the vertical portion 83 can be separated from the substrate on which the plug side anchor 80 is mounted. Thus, when the connection part 42, the base 82, and the perpendicular | vertical part 83 are separated from a board | substrate, when wiring a pattern to the connector mounting part of a board | substrate, it can also wire in the clearance part on a board | substrate, More free. Also, after mounting the connector, even when an external force is applied to the connector toward the board side, the wiring immediately below (separated portion) of the receptacle side anchor 40 and the plug side anchor 80 is cut off, or the board The resist of the shape is peeled off so that the conductor portion is not exposed. In addition, short circuits can be suppressed even when a large current flows momentarily through a wiring or an anchor on the substrate. Further, the distance away from the substrate surface is preferably 0.1 mm or more in terms of insulation function.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above embodiments, and improvements or modifications can be made within the scope of the improved object or the spirit of the present invention.

According to the present invention, it is possible to provide a connector that realizes a secure lock state and a conduction state while realizing miniaturization and low magnification. Moreover, even if the plug is repeatedly inserted and detached, a durable connector with less damage to each member can be provided. Furthermore, even when the fitting position of the receptacle and the plug is misaligned, a connector can be provided that has a small variation and can maintain a secure locked state.
