Description

ELECTRIC CONNECTOR

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector, and more particularly, to an electrical connector for connecting a plurality of electrical cables with wiring of a wiring board.

2. Description of the Related Art Electronic devices such as personal computers and portable electronic devices are equipped with a large number of electronic components and are provided with electrical connectors for connecting a semiconductor integrated circuit (LSI), a wiring board on which other active and passive components are mounted, a liquid crystal display, . In addition, along with the reduction of a height and miniaturization of these electronic devices, the electrical connector is required to have high reliability such as rigidity and durability in addition to high density mounting. Further, even when the connector is repeatedly inserted and withdrawn, it is preferable that the connector is easily handled and the electrical connector is not deformed or damaged.

As the electrical connector, for example, there is one described in Patent Document 1. Patent Document 1 discloses a socket having a slot, a latch rod connected to the socket, a plug inserted in the slot to be coupled to the socket and having a locking portion formed on each of the side walls facing each other, and a pull tab And the latch rod protects the pull tab from being damaged, and when the plug is disconnected from the socket, the pull tab allows the latch rod to be easily released from the lock portion, So as not to be deformed or damaged.

Japanese Utility Model Registration No. 3161161

However, as a result of the inventors' study on the above-described technique of the electrical connector, the following has become clear.

For example, when assembling or repairing an electronic device, the electric connector may be repeatedly inserted and removed. At this time, when the electrical connector is small and thin, it is difficult to operate it by hand. Therefore, it is conceivable that the cable is pulled out by hand when attaching and detaching (pulling out and plugging) the electric connector. Thus, not only the core wire of the cable is broken but also the shell covering the electric connector is deformed, There is also concern.

In the electrical connector disclosed in Patent Document 1, the pull-tab formed on the upper surface of the plug is pulled upward so that the plug can be disconnected from the socket. However, in the case of the electrical connector disclosed in Patent Document 1, since the pull tab is provided at the center of the upper surface of the plug, even if the plug is connected to the socket and the pull tab is folded, the height of the entire electrical connector increases due to its thickness. Such a configuration is not suitable for a connector used in an electronic apparatus requiring thinning. Further, since the hole for attaching the pull tab is formed almost at the center of the upper surface of the plug, it is easily affected by the noise by the hole.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a technique for facilitating detachment and thinning of an electrical connector and reducing the influence of noise in an electrical connector for connecting a plurality of cables and a wiring board It is on.

These and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

Outline of representative ones of inventions disclosed in the present application will be briefly described as follows.

That is, an electrical connector according to the present invention is an electrical connector that can be fitted to a mating connector, comprising: a first shell made of a plate-shaped conductive metal material; a first shell holding a plurality of cables, And a second shell made of a plate-like conductive metal material, wherein the first shell and the second shell are assembled with the housing interposed therebetween. The first shell has a wall piece bent in the direction of the housing on the opposite side of the cable from which the cable is led out. The wall piece has a protruding portion protruding to the outside of the electrical connector, It is possible to attach the pull tab to the protrusion and the hole with the adjacent hole.

Effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows.

(1) Since the side wall of the upper shell is used to attach the pull-tab, the pull-tab can be freely attached and detached even after the assembly of the electrical connector, and the presence or absence of the pull-tab can be selected after completion of assembly.

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

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

(4) Since the lower portion of the hole on the side of the upper shell for the pull-tab attachment is protruded, even if the pull-tab is not attached, the protruded portion can be lifted with a finger or the like to lift the electrical connector, Can be released.

The board-side connector 300 includes a housing 330, a metal shell 310 attached to cover the housing, a terminal 350 inserted and attached upward from the lower side of the housing 330 in the Z1 direction, . The housing 330 of the board-side connector 300 extends in the longitudinal direction (X direction) and supports the terminal 350 at the same interval (pitch) as the terminal 21 of the cable-side connector 100 . The terminal 350 has contact portions 353 and 354 between the board connecting portion 351 and the insertion portion 352 to the housing 330 and the U-shaped mating terminal.

When the board-side connector 300 is fitted to the cable-side connector 100, the respective terminals 21 and 350 are brought into contact with each other to be electrically connected. On the other hand, the shielding performance is improved by the portion 14a of the upper shell 10 of the cable-side connector 100 being in contact with the outer surface of the shell 310 of the board-side connector 300. The lower shell 30 of the cable side connector 100 is electrically connected by making contact with the corresponding portion (reference numeral 312) of the shell 310 of the board side connector 300. [ The locking protrusions 311 at both ends in the longitudinal direction of the board connector 300 are fitted in the holes 13b formed on both side surfaces of the cable connector 100, And the shielding property is improved by contact between the shells (the upper shell 10, the lower shell 30, and the shell 310).

Next, the configuration of the cable-side connector 100 will be described with reference to Figs. 7 to 15. Fig. Fig. 7 is a perspective view showing the entire configuration of the cable-side connector 100 (when the pull-tab is not attached). 8 is a perspective view showing the entire structure of the cable-side connector 100 (when pull-tabs are attached). Fig. 9 is an exploded side view showing the structure of the cable side connector 100 before assembly. 7 to 9, the cable-side connector 100 includes an upper shell 10 (first shell) and a plurality of terminals 21 (see Figs. 2 and 4, etc.) A supported housing 20, and a lower shell 30 (second shell).

The respective core wires 4a of the plurality of cables 4 are electrically connected to each of the plurality of terminals 21. As the cable 4, a coaxial cable or a normal wire can be used. In Fig. 9, the cable 4 is a coaxial cable. However, the present invention is not limited to this. The coaxial cable 4 shown in Fig. 9 is constituted by a core conductor (core wire 4a) such as copper wire, an insulator such as polyethylene, an outer conductor such as braided copper wire, . Each braiding of the coaxial cable 4 is connected to a ground bar 5 of a conductive metal. The ground bar 5 is also electrically connected to the upper shell 10 and the lower shell 30 to receive the ground.

Figs. 10 and 11 are perspective views showing the configuration of the upper shell 10 of the cable-side connector 100, Fig. 10 is a top view, and Fig. 11 is a top view.

10 and 11, the upper shell 10 includes a main body portion 11 extending in the longitudinal direction (X direction) of the cable side connector 100, A first latching piece 12 and a second latching piece 13 which are bent from both ends toward the lower side (Z2 direction), and a front wall piece bent downward in the front side (Y1 side) Wall pieces 14). That is, the first latching piece 12, the second latching piece 13 and the front wall piece 14 are respectively bent toward the housing 20 in the assembled state of the connector 100, (Z direction) with respect to the board-side connector 300 of the first embodiment. The first engaging piece 12 and the second engaging piece 13 are formed at different positions in the forward and backward directions (Y direction, short direction) and at different positions in the longitudinal direction (X direction, longitudinal direction). Specifically, the first latching piece 12 is formed at a position on the lead-out side (Y2 side) of the cable 4 with respect to the second latching piece 13 in the front-back direction (Y direction) (On the side of the terminal 21) with respect to the second engaging piece in the X-direction (X direction). (Hooked) with the lower shell to be described later and the to-be-engaged portion of the housing.

A plurality of holes 14b and 14c are formed in the front wall piece 14 of the upper shell 10. The convex portion 29a of the housing is fitted into the hole 14b to close the hole, Even if the convex portion 29b is fitted into the hole 14c, a hole remains between the convex portions 29b. That is, the hole 14c passes through in the height direction (fitting direction, Z direction) orthogonal to the longitudinal direction (X direction) and the cable lead-out direction (Y direction). By the presence of this hole 14c, Since the pull tab 8 can be attached to the hole 14c after the side connector 100 is assembled, the user can select "attach the pull tab" or "not attach". The front wall piece 14 at the portion corresponding to the hole 14c is protruded (15) on the front side (Y1 side) so that the hole 14c can be made large and the pull tab 8 can be easily attached . The cable side connector 100 can be easily detached from the board side connector 300 by pulling up the pull tab 8 in the upward direction Z1 by attaching the pull tab 8. [ When the pull-tab 8 is not attached, the cable-side connector 100 can be removed by fingering the protruding portion 15 and the convex portion 29 with a finger. The convex portion 29b is not essential, and when the convex portion 29b is not formed, the hole 14c in the longitudinal direction (Z direction) can be ensured as wide as it is.

A plurality of holes 19 are formed on the cable side of the main body portion 11 of the upper shell 10 with a predetermined distance therebetween. The ground bars 5 are connected to the external conductors So that they can be connected by soldering. These holes 19 are formed at substantially the same position as the first engaging piece 12 in the front-rear direction (Y direction) of the connector. 12) of the housing 20 is provided in the vicinity of both ends of the main body portion 11 of the upper shell 10 and has a tongue piece 16 protruded and bent in the housing direction (Z2 direction) As shown in Fig. Further, the upper shell 10 is formed by punching a flat plate-like (plate-like) plate of a conductive metal (such as stainless steel) with a metal mold, and then bending it.

Fig. 12 and Fig. 13 are perspective views showing the configuration of the terminal housing 20 of the cable-side connector 100, Fig. 12 is a top view, and Fig. 13 is a top view.

12 and 13, the housing 20 is provided with a main body portion 22 having a plurality of terminals 21 at predetermined intervals in the longitudinal direction (X direction) There is an area 23 to which the upper shell 10 and the lower shell 20 are attached in both short side regions in the longitudinal direction so as to sandwich the upper shell 10 and the lower shell 20. Convex portions 29a and 29b protruding in all directions are formed on the side surface of the main body portion 22 of the housing 20 in the forward direction (Y1 direction), and the holes 14b And 14c, respectively. Slits 24 extending in the forward and backward directions (Y direction and short direction) and side wall pieces 34 of the lower shell 30 (Figs. 9 and 14, etc.) are formed in the area 23 on both sides of the housing 20 And an attaching portion 25 to which the second latching piece 13 of the upper shell is attached. The attachment portions 26 and 25 are formed with suppression portions 26a and 25a protruding toward the outside (X1 and X2 directions), respectively. The tongues 16 of the upper shell 10 are fitted with grooves 22b in the vicinity of both ends in the longitudinal direction of the housing 20. The housing 20 is made of, for example, an insulating resin, and is integrally molded with the terminal 21 of the conductive metal.

Fig. 14 and Fig. 15 are perspective views showing the configuration of the lower shell 30 of the cable-side connector 100, Fig. 14 is a top view, and Fig. 15 is a top view.

14 and 15, the lower shell 30 includes a main body portion 31 extending in the longitudinal direction (X direction), and a lower shell 30 extending upward from both side ends in the longitudinal direction of the main body portion 31 And the insertion portions 32 and 33 bent in a U shape when viewed from the side in the front side (Y1 direction) of the main body portion 31. The side wall piece 34 is bent toward the front side Since the side wall pieces 34 are engaged with the L pieces 12a of the upper shell 10 at the time of assembling and are engaged with the L pieces 12a of the upper shell 10, the side wall pieces 34 are bent toward the outside (X1 and X2 directions) 35 and projections 36 protruding toward the outer sides (X1, X2 directions) to engage with the first engagement pieces 12 of the upper shell 10 to ensure electrical connection. The lower shell 30 is formed by punching a flat plate (plate-like) plate of a conductive metal (stainless steel or the like) with a die, and then bending the plate.

In the above-described configuration, the cable-side connector 100 is assembled as follows.

(1) By moving the lower shell 30 upward from the lower side (Z1 direction) with respect to the housing 20 integrally molded with the terminal 21, the insertion portions 32 and 33 of the lower shell 30 The side wall pieces 34 of the lower shell 30 are attached to the attachment portions 26 of the housing 20 while being inserted and supported in the corresponding grooves 22a of the housing main body portion 22. The bending piece 35 of the lower shell 30 is positioned below the restraining portion 26a of the housing 20 and the protruding portion 36 is positioned slightly on the slide track of the first latching piece 12 As shown in Fig.

(2) Next, the core wire 4a of the cable is connected to the terminal connecting portion 21a of the terminal 21 by soldering. The cables (4) are aligned and supported by the ground bars (5). Since the cable 4 is a coaxial cable, the ground bar 5 is made of a conductive material. In this embodiment, the ground bar 5 is provided with a portion of the outer conductor (not shown) of the coaxial cable And supports the cable 4 in an exposed state.

(3) Next, the upper shell 10 is attached. Attachment of the upper shell 10 is carried out by first positioning the upper shell 10 on the upper side (Z1 side) of the housing 20 and moving it toward the housing 20 side (Z2 side) (12) of the housing (20) is located inside the slit (24) of the housing (20). At this time, positioning of the upper shell 10 with respect to the housing 20 in the X and Z directions is performed. Thereafter, the upper shell 10 is slid with respect to the lower shell 30 in the Y2 direction (along the slit 24) with the upper shell 10 and the lower shell 30 sandwiched between the housings 20 The L-shaped L-shaped portion 12a of the first latching piece 12 of the upper shell 10 is slid in the direction of extension of the lower shell 12, The upper shell 10 and the housing 20 and the lower shell 30 are integrally fixed by hanging the bent piece 35 of the side wall piece 34 of the upper shell 30. In this state, the ground bar 5 and the upper shell 10 are electrically and physically connected by introducing the solder into the hole 19 of the upper shell 10.

That is, the L-shaped L-piece 12a of the first latching piece 12 is deeply inserted into the lower side of the bending piece 35 of the lower shell 30 to fix the L-shaped piece 12a and the bent piece 35 The housing 20 and the lower shell 30 are pushed toward the upper shell 10 (the main body 11) so that the upper shell 10 and the housing 20 And the lower shell 30 are integrally fixed. The protrusion 36 of the lower shell 30 comes into contact with the inner surface of the first latching piece 12 to secure the electrical connection between the upper shell 10 and the lower shell 30. Since the restraining portion 26a which is a part of the housing 20 is formed on the upper side of the bending piece 35, the force in the upward direction (Z1 direction) caught by the upper shell 10 and the lower shell 30 And finally received by the housing 20. The protrusions 36 of the lower shell 30 may be formed on the upper shell 10 side instead of the lower shell 30. [

On the other hand, the second latching piece 13 of the upper shell 10 is attached to the attachment portion 25 of the housing 20. More specifically, the L-shaped L-shaped piece 13a of the second retaining piece 13 is fitted under the convex-shaped restraining portion 25a of the attaching portion 25. [ Since the restraining portion 25a is formed on the upper side of the L-piece 13a, the force in the upward direction (Z1 direction) can finally be received by the housing 20 as well. The second engaging piece 13 is formed with a hole 13b for fitting with the locking convex portion 311 of the board connector 300. [

The front end of the tongue piece 16 of the upper shell 10 is fitted into the groove 22b of the housing 20 by sliding movement during assembly. Thereby, after the connector assembly, the upper shell 10 is prevented from moving in all directions (Y1 direction).

Convex portions 29a and 29b are formed on the side of the front side (Y1 direction) of the housing 20 and these are fitted in the corresponding holes 14b and 14c of the upper shell 10, And the housing 20 are firmly attached to each other.

According to the above-described electrical connector of the embodiment of the present invention, the projecting portion 15 and the hole 14c are formed in the front wall piece 14 in the front side (Y1 direction) of the upper shell 10, The pull-tab 8 can be attached. Therefore, by pulling the pull-tab 8 upward, the cable-side connector 100 can be easily removed. Further, even when the pull-tab is not attached, the cable-side connector 100 can be easily removed by fingering the protruding portion 15 and the convex portion 29 with a finger.

In addition, since the pull tab 8 is attached to the side surface of the upper shell 10, the pull tab 8 can be freely attached and detached even after the cable side connector 100 is assembled. You can choose. Further, since the pull tab can be folded to the outside of the electrical connector, the fitting height of the entire electrical connector is not affected by the pull tab. Further, since there is no through hole on the upper surface of the upper shell, the influence of noise is reduced.

Although the invention made by the present inventors has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.
