Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector for connecting a plurality of cables to wiring of a wiring substrate.

An electronic device such as a personal computer or a portable electronic device is equipped with a plurality of electronic components, and a wiring board, a liquid crystal display, an RF circuit, etc., which are mounted with a semiconductor integrated circuit (LSI) or other active passive components, are required. Electrical connector. In addition, in order to reduce the thickness and size of these electronic devices, the electrical connector is required to have high reliability in connection with high-density mounting, and has rigidity and durability. Moreover, even when the insertion/removal operation of the connector is repeated, it is desirable that the processing can be easily performed and the electrical connector is not deformed or damaged.

An electrical connector described in, for example, Patent Document 1 (Japanese Laid-Open Patent No. 3161161) is known as an electrical connector. The electrical connector of Patent Document 1 is provided with: a socket having a socket; a latching lever connected to the socket; inserted into the socket for coupling to the socket, and each of the opposite side walls is provided with a locking portion a plug; and a pull strap provided on the plug, the latch handle is for protecting the drawstring from being damaged, and when the connection of the slider is released from the socket, the pull tab can easily release the latch handle from the lock portion, and pull The belt is not prone to deformation or damage.

[Patent Document 1] Japanese New Patent No. 3161161

Moreover, the inventors of the above-described techniques for the electrical connector are inspected. As a result of the discussion, I found the following.

For example, when an electronic device is assembled or repaired, the insertion and removal of the electrical connector may be repeated. At this time, in the case where the electrical connector is small and thin, it is difficult to operate with a human hand. Therefore, when the electrical connector is attached or detached (plugged and unplugged), there is a case where the cable is pulled by the hand, and therefore, not only the core wire of the cable may be broken, but also the electrical connector may be covered. The outer casing is deformed, detached, etc.

In the case of the electrical connector described in Patent Document 1, the connection of the plug can be released from the socket by pulling the pull tape provided on the upper surface of the plug upward. However, in the case of the electrical connector described in Patent Document 1, since the draw tape is present at a substantially central portion of the upper surface of the plug, even if the plug is attached to the socket and the draw tape is folded, the thickness thereof is caused. The height of the entire electrical connector becomes high. In the case of such a configuration, it is not suitable as an electrical connector for use in an electronic device that is required to be thinned. Further, since the hole for attaching the draw tape is provided at a substantially central position on the upper surface of the plug, the hole is easily affected by noise.

Therefore, the first object of the present invention is to provide an electrical connector for connecting a plurality of cables to a wiring board, and to provide a technique for facilitating attachment and detachment of the connector, which can be made thinner and can reduce the influence of noise.

The above and other objects and novel features of the present invention will be apparent from the description and drawings.

In the invention disclosed in the present application, the outline of a representative invention will be briefly described as follows.

That is, the electrical connector of the present invention is an electrical connector that can be fitted to the target connector, and has a first outer casing made of a plate-shaped conductive metal; holds a plurality of cables and includes a core wire with the aforementioned cable a housing of a plurality of terminals that are connected to each other; and a second outer casing formed of a plate-shaped conductive metal, wherein the first outer casing and the second outer casing are assembled by sandwiching the casing. The first outer casing has a wall piece that is bent toward the casing direction on a side opposite to the side from which the cable is led out, and the wall piece has a protruding portion that protrudes outward of the electrical connector; and a portion adjacent to the protruding portion The hole can be attached to the protruding portion and the hole.

In the invention disclosed in the present invention, the effects obtained by the representative invention will be briefly described as follows.

(1) Since the hole on the side surface of the upper casing is used for the attachment of the draw tape, the draw tape can be freely attached and detached even after the electrical connector is assembled, and the presence or absence of the draw tape can be selected after the assembly is completed.

(2) Since the draw tape can be folded outside the electrical connector, the fitting height of the entire electrical connector is not affected by the draw tape.

(3) Since there is no through hole on the upper surface of the upper casing, the influence of noise can be reduced.

(4) Since the lower portion of the hole on the side of the upper casing for the attachment of the strap is protruded, the finger or the like can be hooked thereto even if the strap is not attached. The protruding part is used to lift the electrical connector, and the connection of the connector is easily released.

Further, a groove 22b is provided in the vicinity of both ends in the longitudinal direction of the casing 20, and the tongue piece 16 of the upper casing 10 is fitted. Further, the casing 20 is made of, for example, an insulating resin, and is integrally molded with the terminal 21 of the conductive metal.

14 and 15 are perspective views showing the structure of the lower casing 30 of the cable side connector 100, wherein Fig. 14 is a view from the upper right side, and Fig. 15 is a view from the upper left side.

As shown in FIGS. 14 and 15, the lower casing 30 has a main body portion 31 extending in the longitudinal direction (X direction); and a bent portion from the both end portions in the longitudinal direction of the main body portion 31 toward the upper side (Z1 direction) The side wall piece 34; and the front side (Y1 direction) of the main body part 31 are bent into the U-shaped insertion parts 32 and 33 in the side view. Further, the side wall piece 34 has a bent piece 35 which is bent toward the outer side (X1, X2 direction) for the side wall piece 34 to be hooked to the L piece 12a of the upper case 10 at the time of assembly; and for the upper case The first locking piece 12 of 10 is engaged to ensure electrical connection, and the projection 36 protrudes outward (X1, X2 direction). Further, in the lower casing 30, similarly to the upper casing 10, a flat (plate-shaped) conductive metal (stainless steel or the like) is formed by pressing a die and then bending.

In the foregoing structure, the cable side connector 100 is assembled in the following manner.

(1) By moving the casing 20 integrally formed with the terminal 21, the lower casing 30 is moved from the lower side upward (Z1 direction), so that the insertion portions 32, 33 of the lower casing 30 are inserted and held in the casing body portion. The corresponding groove 22a of 22 is attached to the mounting portion 26 of the casing 20 by the side wall piece 34 of the lower casing 30. Thereby, the bent piece 35 of the lower casing 30 is located at the lower side of the restraining portion 26a of the casing 20, and the projection 36 is slightly protruded on the sliding rail of the first locking piece 12.

(2) Next, the core wire 4a of the cable is welded to the terminal connecting portion 21a of the terminal 21. The cables 4 are held in alignment by the grounding bars 5. Further, the grounding rod 5 is made of a conductive material. In the present embodiment, since the cable 4 is a coaxial cable, the grounding rod 5 holds the cable 4 in a state in which the outer conductor (not shown) of the coaxial cable is exposed.

(3) Next, the upper casing 10 is mounted. The upper casing 10 is first placed on the upper side chamber (Z1 side) of the casing 20, and then moved toward the casing 20 side (Z2 side), so that the first locking piece 12 of the upper casing 10 is located in the casing 20. The interior of the gap 24. At this time, the positioning of the upper casing 10 in the X direction and the Z direction of the casing 20 is performed. Then, in a state where the upper casing 10 and the lower casing 30 sandwich the casing 20, the upper casing 10 pair 30 is slidably moved along the slit 24 in the Y2 direction (the short direction, the rear direction, and the direction in which the cable 4 is led). Thereby, the L piece 12a of the first locking piece 12 of the upper casing 10 is hooked on the bent piece 35 of the side wall piece 34 of the lower casing 30 so that the upper casing 10 and the lower casing 30 are integrally fixed. In this state, by going to the outside The hole 19 of the casing 10 flows into the solder to electrically and physically connect the grounding rod 5 to the upper casing 10.

In other words, the L-shaped L-piece 12a of the first locking piece 12 enters the lower side of the bent piece 35 of the lower casing 30 and is fixed, so that the L-shaped piece 12a is in close contact with the bent piece 35 and the restraining piece 26a. The housings 20 and 30 are pressed toward the upper casing 10 (the body portion 11) such that the upper casing 10 and the casing 20 and the lower casing 30 are integrally fixed. Further, the projection 36 of the lower casing 30 is in contact with the inner surface of the first locking piece 12 to ensure electrical connection between the upper casing 10 and the lower casing 30. Further, since the suppressing portion 26a which is a part of the casing 20 is provided on the upper side of the bent piece 35, the (Z1 direction) force applied to the upper direction of the upper casing 10 and the lower casing 30 can finally be the casing. 20 to undertake. Furthermore, the protrusion 36 of the lower casing 30 may be disposed on the upper casing 10 side instead of the lower casing 30.

Further, the second locking piece 13 of the upper casing 10 is attached to the mounting portion 25 of the casing 20. Specifically, the L-shaped L piece 13a of the second locking piece 13 is fitted in the lower surface of the convex suppression portion 25a of the attachment portion 25. Since the restraining portion 25a is provided on the upper side of the L piece 13a, the force in the upward direction (Z1 direction) can finally be received by the casing 20 in the same manner. Further, the second locking piece 13 is formed with a hole 13b for fitting with the locking convex portion 311 of the substrate-side connector 300.

Further, the front end of the tongue piece 16 of the upper casing 10 is fitted into the groove 22b of the casing 20 by sliding movement during assembly. Thereby, the upper casing 10 does not move in the forward direction (Y1 direction) after the connector is assembled.

Further, a convex surface is formed on the side surface of the front side (Y1 direction) of the casing 20. The portions 29a, 29b are embedded in the corresponding holes 14a, 14b of the upper casing 10, so that the mounting of the upper casing 10 and the casing 20 becomes stronger.

According to the electrical connector of the embodiment of the present invention described above, since the wall piece 14 is provided with the protruding portion 15 and the hole 14c before the front side (Y1 direction) of the upper casing 10, the draw tape 8 is attached thereto. Therefore, the cable side connector 100 can be easily removed by lifting the draw tape 8 upward. Further, even when the draw tape is not attached, the cable side connector 100 can be easily removed by hooking the finger to the protruding portion 15, the convex portion 29, and the like.

Moreover, since the hole of the side surface of the upper case 10 is used for attaching the draw tape 8, the draw tape 8 can be detachably attached even after the cable side connector 100 is assembled, and it is possible to select whether or not to pull after the assembly is completed. With 8. Moreover, since the draw tape can be folded outside the electrical connector, the fitting height of the entire electrical connector is not affected by the draw tape. Moreover, since there is no through hole on the upper surface of the upper casing, the influence of noise can be reduced.

As described above, the inventions have been developed by the inventors of the present invention in detail, but the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
