Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention particularly relates to a connector insertion/removal mechanism that allows male contacts to be smoothly inserted into and removed from female contacts in a multipolar connector with reduced force.

Prior art and its problems When holding a multi-pin connector with your fingertips and inserting or pulling out a male contact with a long insertion/extraction stroke into a female contact, it is not only difficult to pull out due to high resistance. There were drawbacks such as improper insertion/extraction posture, which could deform or damage the male or female contacts. Conventional low-resistance insertion/extraction type connectors also have the risk of deformation due to poor posture when they are inserted or removed using fingertips.

Purpose of the invention The present invention aims to solve the above-mentioned drawbacks by making it possible to smoothly insert and remove male contacts into and out of female contacts in multi-pole connectors with very little operating force and with proper insertion and removal postures. It is.

The base plate 2 is provided with a crimp terminal mounting hole 2a into which a crimp terminal 3 is removably mounted, and a male contact 6 (described later) is provided at the bottom 2b of the crimp terminal mounting hole 2a.
An insertion hole 2c is drilled through which one of the contacts 6a is inserted, and a nut 4 having a large diameter female screw 4a and a small diameter female screw 4b is fixed in the mounting hole 4' in the center of the base 2. ing. Reference numeral 5 denotes a base for a male contact, and the outer shape of the base 5 is formed to be the same as the outer shape of the base 2 and, therefore, the inner shape of the case 1. Reference numeral 6 designates a male contact in which a flange portion 6b is formed in the middle portion of small-diameter rod-shaped contacts 6a, 6a.

The base plate 5 has a loose insertion hole 5a into which the other rod-shaped contact 6a of the male contact 6 is inserted, and a loose insertion hole 5b into which the flange 6b of the male contact 6 is loosely inserted. Both loose insertion holes 5a, 5
A locking step portion 5c is formed in the continuous portion b, and the collar portion 6b of the male contact 6 is locked to this locking step portion 5c, thereby changing the mounting position of the male contact 6 to the base plate 5. is regulated.

In this way, the male contact 6 is inserted into the loose insertion hole 5 of the base plate 5.
a, 5b, and one rod-shaped contact 6a
is made to protrude upwardly from the hole 5b, and the other rod-shaped contact 6a is made to protrude downwardly from the hole 5a.

Next, one rod-shaped contact 6a of the male contact 6 attached to the substrate 5 is inserted into the crimp terminal 3 attached to the substrate 2, the two substrates 2 and 5 are overlapped, and both are screwed into the female screw 4b. Tighten and fix in step 7 to assemble a connector base from which a large number of male contacts can protrude downward.

Both bases 2 and 5 integrated in this way are housed in the case 1, and the contacts 6a of the male contacts 6 protruding from the base 5 are connected to the bottom plate 1a of the case 1.
It is made to removably protrude to the outside from the insertion hole 1c bored in the hole 1c. Reference numeral 8 denotes a cover plate detachably fitted to the open end of the case 1. For example, washers 9a and 9b are provided in the center of the cover plate 8 to rotate the operating shaft member 10 in a fixed position. Support through. This operating shaft member 1
A male screw 10a is formed at the tip of the shaft portion 10c existing in the case 1 of 0, and this male screw 10a is screwed into a female screw 4a provided at the center of the base plate 2. The operation shaft member 10 and the base plate 2 may be screwed together by, for example, using a female thread on the operation shaft member 10 and the base plate 2.
A male thread can be formed and screwed together.

10b indicates a knob portion of the operating shaft member 10. 1
1 is a cable 1 crimp-connected to the crimp terminal 3
2, 1d is an upward hook-shaped locking piece formed at the edge of the opening of the case 1, and 8a is a downward hook-shaped locking piece formed at both ends of the cover plate 8. Then, the locking pieces 8a and 1d are hooked and engaged with each other to removably fit the lid plate 8 into the opening of the case 1.

In the above configuration, when the operating shaft member 10 is rotated, for example, to the left, a pulling force is applied to the center portions of the bases 2 and 5, and the outer edges of the bases 2 and 5 are guided to the inner surface of the case 1 while being guided in the direction of arrow A ( When the operating shaft member 10 is rotated to the right, a pressing force is applied to the center portions of the bases 2 and 5, and the outer edges of the bases are similarly guided to the inner surface of the case in the direction of arrow B (see Fig. 1). (see figure). As a result of the leftward rotation of the operating shaft member 10, the bases 2 and 5 are moved in the direction of arrow A, the male contact 6 rises within the insertion hole of the case bottom plate 1a and retreats in the direction of being accommodated in the case 1. .

That is, the male contact 6 is pulled out from the female contact of the socket (not shown), and the connection between the male contact 6 and the female contact is released.

Next, by rotating the operation shaft member 10 in the opposite direction to the previous rotation, the bases 2 and 5 are moved in the direction of arrow B, and as a result, the male contact 6 is lowered and the bottom plate 1 of the case 1 is moved.
It protrudes longer from a. That is, the same male contact 6 is a female contact (not shown) of the socket.
The same male contact 6 and the same female contact are connected.

Effects of the invention According to the invention, by rotating the operating shaft member provided at the center of the case cover plate, a lifting force and a pushing force are applied to the center of the board housed in the case, and the outer edge of the board is is pulled up or down using the inner surface of the case as a guide, and the male contact provided on the base is advanced and retreated within the insertion hole of the case bottom plate, and the male contact is connected to and disconnected from the female contact (not shown). Therefore, it is possible to easily insert and remove the female contact while maintaining the proper insertion and removal posture of the base and the male contact, which has the advantage of preventing deformation and damage to the contact. This has the advantage that it can be performed smoothly with only a slight operating force. In particular, the present invention is suitably used as an insertion/extraction mechanism for a connector in which male contacts having a relatively long insertion/extraction stroke are densely arranged.

Furthermore, by simply housing the board in the case, fitting and removing the cover plate provided with the operating shaft member into the case, and performing the above-mentioned screwing and unscrewing, assembly, removal and disassembly of the board can be easily performed, and the board can be easily removed from the case. By fitting the cover plate into the case while regulating the inner surface, alignment between the operating shaft member and the base can be easily obtained.
