Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper for a terminal connector for fixing the terminal to the terminal connector by simply pushing the stopper of the terminal connector when mounting the terminal connector on the terminal of the lead wire. Regarding the device.

[0002]

2. Description of the Related Art Conventionally, male and female terminal connectors have been previously mounted on lead wires for connecting various electric and electronic devices to each other, and the lead wires are connected through these male and female terminal connectors. Mutually, that is, mutual electrical connection of each device is made. If such male and female terminal connectors are used, not only the connecting work between the respective devices becomes easy, but also the replacing work of the devices becomes easy.

This type of terminal connector has a mounting hole for the conductive terminal in the connector body in order to couple the connector body with the conductive terminal on the lead wire side, and the conductive terminal for the lead wire is mounted in this mounting opening. The conductive terminals are engaged with each other in the connector main body only by inserting them to prevent them from coming off. Further, in the terminal connector, in order to strengthen the coupling between the conductive terminal and the connector body, a push-in groove communicating with the mounting opening is formed in the connector body, and a stopper capable of being pushed into the push-in groove. There is one provided. The stopper has first and second claws at both ends, and is integrally connected to the connector body via a spring portion.

Therefore, in the above-described terminal connector having the stopper, after inserting the conductive terminal of the lead wire, the first claw of the stopper is pushed to one end of the groove by utilizing the elastic deformation of the spring portion. First, push in from the diagonal direction, then push the second pawl of the stopper into the other end of the push groove, and then use the elastic return force of the spring portion to return the above-mentioned push in the diagonal direction of the stopper. With the first and second claws at both ends of the stopper being locked from both ends to both ends of the push groove, the pushing of the stopper into the push groove is completed. When the stopper is pushed in this way, the stopper clamps the conductive terminal of the lead wire between the stopper and the connector main body, thereby ensuring the connection between the conductive terminal and the connector main body. You can

By the way, since the above-mentioned terminal connector is a small part, the stopper thereof is even smaller. Therefore, the pushing operation of the stopper is conventionally performed manually, that is, It is done using the operator's own fingertips. To press the stopper with your fingertips, face the pressing groove and
Since it is necessary to push in the second pawl at the same time while pushing the pawl side in the diagonal direction, particularly when pushing the second pawl into the pushing groove, the burden on the fingertip is large and the pushing work of the stopper is facilitated. There is a problem that can not be done.

Moreover, when the second claw is pushed into the push-in groove when the first claw is not pushed in obliquely enough, the second claw interferes with the end of the push-in groove,
The second claw may be damaged, and in this case, the stopper cannot be pushed into the pushing groove. The present invention has been made based on the above-mentioned circumstances, and its object is to make it possible to easily and surely press the stopper into the pressing groove of the terminal connector with a simple structure, and to improve the efficiency of the pressing operation. An object of the present invention is to provide a stopper pushing device for a terminal connector that can be realized.

[0007]

A stopper pushing device for a terminal connector according to the present invention is applied to a terminal connector of the type described above, in which the pushing groove is exposed and the stopper is in a free state. The holder includes a holder that holds the connector body in a detachable manner, and a plunger that is movable so as to come into contact with and separate from the pushing groove of the connector body on the holder in an oblique direction.

The plunger is formed so as to be continuous with the pressing surface facing the pressing groove of the connector body on the holder so as to be substantially parallel to the pressing groove, and rises from the pressing surface toward the holder. The step has a step, whereby the plunger is moved toward the holder, and in the process of pressing the stopper while the pressing surface slides on the outer surface of the stopper of the connector body, the spring portion is elastically deformed, The first claw of the stopper is pushed into one end of the pushing groove, and after the edge defined between the outer surface of the stopper and the second claw contacts the step, the step is pressed by the step. , The first claw side of the stopper is pushed deeply into one end of the pushing groove in an oblique direction, and at the same time, by sliding the end edge of the stopper along the step, the second claw of the stopper is pushed. The stopper is pushed into the other end of the insertion groove, and thereafter, when the engagement between the edge and the step is released, the stopper is returned by pushing the stopper in the oblique direction by the elastic return force of the spring portion. The stopper can be pushed into the push-in groove in a state where both the first and second claws are locked to both ends of the stopper push-in groove from the inside.

[0009]

According to the above-described terminal connector pushing device, the stopper of the connector body can be pushed into the pushing groove by merely holding the terminal connector in the holder, that is, the connector body, and then moving the plunger toward the holder. Will be pushed into.

That is, when the stopper is pressed by the pressing surface of the plunger, the spring portion is elastically deformed, so that the first claw side of the stopper is pushed into one end of the push-in groove. When it comes into contact with the step, thereafter, the stopper presses the step, so that the first claw of the stopper is pushed deeply into the one end of the pushing groove in the oblique direction, and at the same time, along the step. By sliding the end edge of the stopper, the second claw of the stopper is also pushed into the other end of the pushing groove. When the end edge of the stopper is disengaged from the step, the oblique pushing force is released, and the stopper is returned by the elastic return force of the spring portion. The second claws engage with both ends of the pushing groove from the inside, whereby the pushing of the stopper into the pushing groove is completed.
