Description

[Detailed Description of the Invention] [Field to which the invention pertains] The present invention relates to a connector comprising a socket and a plug for connecting a large number of terminals.

[Prior art]

When this type of connector has a large number of terminals, strong force is required to engage and remove them. For this reason, the inventor of the present invention had already proposed a system in Utility Model Application No. 54-149693 that uses a gear to engage and disengage the socket and plug with strong force, but this would result in expensive gear machining and insufficient locking. becomes. It has also been proposed to use a cam to connect and remove the socket and plug, but the device becomes larger and the lock is insufficient.

[Purpose of invention]

The present invention eliminates such drawbacks, and uses the lever principle to engage and remove the socket and plug with strong force, and also uses the dead center formed between the shaft and the operating lever to connect the socket and plug. It is designed to firmly lock the plug.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

Sockets 1 that fit into each other as shown in Figures 1 to 3
A large number of terminals 3, 3 are provided on one side of the opposing surface of the plug 2.
. . . and holes 4, 4 . . . into which the terminals 3, 3 . . . fit are provided on the other side. Note that these terminals 3 and holes 4 may be provided in the socket 1 and plug 2, respectively.

Pivot shafts 5, 5 are installed on both sides of the plug 2, and a hole 7 of an operating lever 6 is fitted into one of the pivot shafts 5 for pivoting, and an adjacent portion above the hole 7 of the operating lever 6 is attached. A pin 8 is implanted at the position.

The above-mentioned pivots 5, 5 are fitted to slide in the horizontal part of an L-shaped hole 12 of an engagement plate 11 having a claw 10 at the tip of the upper end, and the above-mentioned pin 8 is fitted into the vertical part of this L-shaped hole 12.
be a tight fit. This engagement plate 11 is resiliently repelled by a spring 13 so that the pawl 10 moves upward. Note 1
6 is a stopper. Further, the upper portions of the engagement plates 11, 11 are connected by a connecting portion 14, and a protrusion 15 is provided on the upper surface of the plug 2, which comes into contact with the lower surface of the connecting portion 14 when the engaging plates 11, 11 are retracted.

Rectangular parallelepiped housing-shaped fitting part 2 at the tip of the socket 1
A groove 21 in which the pawl 10 of the engagement plate 11 engages is provided on the lower surface of the upper part of the engagement plate 11.

Next, the operation of this device will be explained.

As shown in FIG. 2, the fitting portion 20 of the socket 1 is fitted into the plug 2 with the operating lever 6 in the upper position and the engagement plate 11 moved forward. As a result, the grooves 21 of the fitting portion 20 engage with the claws 10, 10, and the ends of the terminals 3, 3... are temporarily fitted into the holes 4, 4.... Next, the lever 6 is rotated clockwise as shown by the arrow in FIG. As a result, the pin 8 is pushed through the L-shaped hole 12 into the engagement plate 1 with a strong force due to the lever principle.
1 to the right in Fig. 2 A and B, and
The engagement of the socket 1 with the groove 21 causes the socket 1 to move toward the plug 2, and the terminals 3, 3, . . . fit completely into the holes 4, 4, . When the lever 6 is turned 90 degrees, the socket 1 and the plug 2 are completely fitted together, and the pin 8 comes into contact with the rear side of the pivot shaft 5 as shown in FIG. The rear wall of the hole 12 is in close contact. Therefore, the engagement plate 11 cannot move forward and locks the fitting between the socket 1 and the plug 2. Further, at this time, the connecting portion 14 of the engagement plate 11 rides on the protrusion 15, and its downward rotation is prevented. Therefore, the engagement between the claw 10 and the groove 21 never comes off.

When removing socket 1 and plug 2, the operation is completely reversed.

[Effect of the invention] As described above, in the present invention, when the engagement plate slides backward, the pin touches the rear side of its pivot, so the operating lever and the engagement plate are completely moved by the dead center formed thereby. At that time, the connecting part of the engagement plate rides on the protrusion provided on the socket or plug, so the engagement plate will not come off the groove and the socket and plug will be securely locked. be. Further, in the present invention, the socket and plug are first fitted together and then completely fitted together using the operating lever 6, so that even if a thick cable is attached, the operation is easy.
