Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector device, and more particularly to a connector device equipped with an auxiliary insertion/extraction jig for simultaneously inserting and removing a socket type multipolar connector having a width of 20 or more.

FIG. 1 is a sectional view showing the structure of a conventional multi-pole connector device for connecting wiring boards. In the figure, the connector device mainly connects a first wiring board 1 and a second wiring board. The wiring board 2, the housing 3, the contacts 4, and the jig 5 are all covered.

As shown in FIG. 2, the housing 3 has a rectangular frame body, and a large number of contacts 4 are arranged on the inside, and a groove 6 is formed on the outside.

As shown in FIG. 3, the contact 4 is an S-shaped elastic conductor housed in a penetrating square hole, and contacts the first and second wiring boards 1 and 2 to electrically connect them. As such, the ends of the contacts 4 always protrude slightly from both sides of the housing 3.

The groove 6 has a length approximately equal to the inner diameter of the frame body, and as shown in FIG. The lower left corner in the figure of the rectangular cross section is chamfered in a warp shape.

As shown in FIG. 1, one side of the housing 3 has a first wiring board 1 fixed to it with bolts, and a second wiring board 2 slightly protruding from the other side of the housing 3. A stepped portion 3a shallower than the thickness of the wiring board 2 is formed so as to be accommodated therein.

As shown in FIG. 5, the jig 5 is a metal fitting bent into an L-shape, and its horizontal line 5a is pressed into contact with the side edge of the second wiring board 2. A substantially L-shaped guide groove 9 starting from the opening is formed at a position where the vertical line 5b corresponds to the bar 7 (see FIG. 4).

The opening 8 of the guide groove 9 has a width that allows the bar 7 to pass in a direction perpendicular to the longitudinal direction, and the parallel portion 9a along the longitudinal direction has a height that allows the bar 7 to pass in the longitudinal direction. The inner angles of are chamfered to form a slope 9b.

Therefore, the second wiring board 2 is placed on the stepped portion 3a of the housing 3, and then a jig 5 is placed on each side edge of the second wiring board 2.
, and the vertical edge 5b is aligned with the opening 8 of the guide groove 9.
and bar 7 at corresponding positions.

Next, when each jig 5 is moved in the direction of the arrow shown in FIG. 5, the inclined part 9b of the guide groove 9 slides on the lower surface of the bar 7, and the end of the parallel part 9a abuts against the bar 7.

At that time, the jig 5 moves the second wiring board 2 to the first wiring board in FIG.
Since the wiring boards 1 and 2 are placed close to the wiring board 1, the wiring boards 1 and 2 can be brought into close contact with the contacts 4.

Further, when each jig 5 is moved in the opposite direction to that described above, the bar 7 returns to the opening 8 of the guide groove 6, and the jig 5 can be detached from the housing 3, so that the second wiring board 2 By removing it from the stepped portion 3a, the electrical contact with the first wiring board 1 can be easily cut off.

However, as shown in FIG. 6, instead of the contact 4 (see FIG. 1), a U-shaped elastic plate is used as a female connecting portion 1 whose opposing free ends are biased in the direction of contacting each other.
0 is arranged in the housing, and a post 11 is implanted at a position corresponding to the female connection part 10 for insertion into this female connection part 10 instead of the second wiring board (see FIG. 1). In the so-called socket type connection structure including the wiring board 12, the configuration using the jig 5 described above has a fatal drawback of being impossible to remove.

In addition, the bar 7 is normally molded integrally with the housing 3 made of plastic, and as a result, the bar 7 is subject to severe wear, which may result in insufficient operation amount or
Since the contact between the guide groove 9 and the guide groove 9 is a surface contact, there is a drawback that the friction between the two is large and the operating force of the jig 5 is large.

Moreover, in the socket type connection structure shown in FIG. 6, since connections cannot be made at once, the jigs 5 must be operated one by one, which results in uneven insertion amounts and implants on the wiring board 12. There were problems such as bending of the installed post 11 and extremely poor efficiency.

The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art, and
Insertion and removal are possible with either the pressure contact type or socket type connection method, reducing the operating force of the jig, ensuring uniform insertion and removal with a single operation, and ensuring that the bar remains stable even with repeated operations. It is an object of the present invention to provide a connector device that does not cause insufficient operation due to wear.

In order to achieve this purpose, the present invention uses a pair of rectangular female and male connectors and four L-shaped jigs, and the grooves formed on each side edge of the female connector have a circular cross section to prevent wear. The horizontal edges of the jig, which is similarly made of highly wear-resistant hard metal, are arranged in two rows, and the male connector is loosely sandwiched between the side edges, and the vertical A guide groove is formed on the edge, and when the pin is inserted into the groove and moved along the direction of the groove, the male connector is brought into contact with and separated from the female connector. A protrusion is formed on the horizontal edge for the male connector to be held, the ends of adjacent jigs are connected via a link member, and at least one link member is provided with a rotating means. It is a feature.

Hereinafter, the present invention will be described in detail based on an illustrated embodiment.

FIG. 7 is an external perspective view showing one embodiment of the present invention, and in this figure, the connector device is mainly composed of a male connector 13, a female connector 14, a jig 15, and a link member 16.

8 to 10 show the female connector 14. FIG.

In these figures, the female connector 14 has a generally hollow rectangular shape, with grooves 1 near each side edge along each side edge.
7 is formed, and a pin 18 is inserted across this groove 17.
They are inserted and implanted one by one.

This pin 18 is made of a hard metal with good wear resistance, such as stainless steel.

Moreover, inside each groove 17, a large number of female connecting parts 1 are provided along the groove.
9 are arranged.

The shape of each female connecting portion 19 is the same as that shown in FIG. 6, but the shape is not limited to this.

The four corners of the female connector 14 are cut out, leaving a bottom portion 14a, so that link members to be described later can be placed therein.

Figures 11 and 12 show the jig 15, in which the jig 15 has two rows of horizontal edges, a first horizontal edge 20, 20... and a second horizontal edge. Edge 21.
21... and the vertical edge 22 are integrally formed.

The two rows of horizontal edges are formed by making cuts of the same depth at equal intervals in the longitudinal direction and then bending them at shallow positions. The second horizontal edges 21, 21 are shaped by bending at a deep position.
Consisting of alternating arrangement.

The two rows of horizontal edges are not limited to the above-described configuration, but may be configured by fixing two L-shaped members 15ai5b by welding or the like, as shown in FIG. 13.

The advantage in this case is that it is easy to manufacture. Also the 12th
As clearly shown in the drawings and FIG. 13, a plurality of downwardly directed protrusions 23 are formed on the first horizontal edge 20, and a plurality of upwardly directed protrusions 23 are formed on the second horizontal edge 21.

These protrusions 23 support the side edges of the male connector from both sides.

The vertical edge 22 has an opening 2 corresponding to the position of the pin 18.
4, a first horizontal portion 24a against which the pin 18 engaged with the opening 24 abuts, and an inclined portion 24 against which the pin 18 abuts against the first horizontal portion 24a is raised as the jig 5 moves.
b, and a second horizontal portion 24c extending horizontally from the end of the inclined portion 24b.

The guide groove 25 is finished smoothly in order to smoothly slide on the pin 18.

Further, both ends of the vertical edge 22 form a recess that opens on the same side as the opening 24, and both ends of the vertical edge 22 constitute a part of this recess, and are attached to a link member 16 to be described later. Hanging 26 is impressive.

From FIG. 14 to FIG. 16, the link member 16 and the jig 1 are shown.
The connected state with the end portion (hook) 26 of 5 is shown.

In these figures, the link member 16 has an approximately one-circular shape, and is pivotally attached to three corners of a female socket (not shown) so as to be swingable about the approximate center of the circle.

A long hole 16a is bored in both circumferential ends of the link member 16 toward the pivot point 28.
A hook 26 of the jig 15 is inserted into a.

Therefore, adjacent jigs are kept perpendicular to each other, and movement of one jig causes movement of the other jig.

Note that one of the three link members has a hexagonal recess 15b, which serves as a rotation means, bored in the center of rotation.
As shown in the figure, the common ends of a hexagonal bar 27 bent into an L-shape are fitted into each other.

When the hexagonal bar 27 is rotated in the direction of the arrow in the figure, the link member 16 swings and the elongated hole 16 of the link member 16 swings.
a pushes the hook 26 inserted into this hole to release the jig 15.
move in a specified direction.

Therefore, in the connector device of the present invention, since the male connector is held between the two rows of horizontal edges of the jig, it can be inserted and removed even on a post-type wiring board, and the two rows of horizontal edges are provided with protrusions. Due to the engagement of the circular pin with the guide groove on the vertical edge, which has a strong shape and smooth finish, there is less frictional force when moving the jig, and the structure is simple, and all the jig can be operated in one operation. Therefore, the efficiency is high, insertion and removal are performed uniformly, and the occurrence of bending of the post is prevented.
