Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a connector holder in a press-type connecting device for connecting a communication line and a connector, which is used in a telephone transmitter/receiver or the like.

Conventional Technology Conventionally, the connection between a telephone transmitter/receiver and a communication line has been made using screws, but depending on the location where the transmitter/receiver is installed, it may be very difficult to do the screwing. In recent years, the use of plug-in connectors has become common in order to make connection work easier, as the functions of transmitters and receivers have diversified and the number of core wires in communication lines has increased. This type of connector 1 is shown in FIGS. 6 to 8.
As shown in the figure, it has a rectangular shape, and vertical grooves 4 corresponding to the number of core wires 3 of the communication line 2 are provided inward from the top surface located at one end of the rectangular parallelepiped. 4..., plate-shaped electrical terminals 6... each having a blade portion 5... formed on its lower end are inserted with their upper ends protruding from the upper surface of the connector 1. In addition, the connector 1 is provided with an insertion port 7 for inserting the communication line 2 at the side located at the other end, and a communication hole connecting the insertion port 7 and the lower end of the vertical groove 4 inside. 8 is formed. Then, insert the core wires 3 of the communication wires 2 lined up in a row into the insertion opening 7 of the connector 1 by peeling off the outer sheath 9 at the tip and exposing the core wires 3, so that the tip of each core wire 3 has a vertical groove 4... After inserting the electrical terminal 6 until it reaches the lower end, press the upper end of the electrical terminal 6 downward, and use each blade 5 of the electrical terminal 6 to penetrate the coating of the core wire 3. Terminal 6...
and the core wire 3 are electrically and mechanically connected. Conventionally, the electrical terminal 6...
The press-type connecting device for pressing the upper end of
A press rod with a push claw on the lower end and connector 1
In order to hold the connector 1, a holder for the connector 1 is provided, which is placed directly below the press rod. The connecting device may be one that includes a press rod and a holder, or, in order to make the work more efficient, two sets that can be used to double the work with one press operation. However, in both cases, the holder was directly fixed to the connecting device.

Problems to be Solved by the Invention Since the holder of the connector 1 of the conventional connecting device as described above is fixed directly to the connecting device, when the holder is replaced, that is, the connector 1 to be connected is When changing to a different type, it is necessary to replace the entire holder. Furthermore, in the two-set type connecting device, the spacing between the two holders must be matched to the spacing between the two press rods, but each electrical terminal 6 of the connector 1 is connected to each push claw 37 at the tip of the press rod. It was difficult and time-consuming to make adjustments so that they matched.

The present invention was developed in consideration of the above problems, and it improves work efficiency by using a plurality of holders, and also makes only the part of the holder that holds the connector 1 detachable. It is an object of the present invention to provide a device that can accommodate a wide variety of connectors to be connected, allows economical replacement of holders, and allows easy adjustment of the spacing between a plurality of holders. purpose.

Means for Solving the Problems The present invention provides a press-type connecting device equipped with a press rod that can be raised and lowered, a base member positioned and fixed below the press rod, and arranged on the upper surface of the base member, A plurality of nest members in which adjacent members can be horizontally moved toward and away from each other and each can be fixed to a base member, and each nest member is detachably fixed to the upper part of the nest member, and
It is composed of a block member having a holding groove capable of holding the connector in a predetermined position, and a plurality of types of block members are provided, each having a shape of the holding groove depending on the type of the connector to be connected.

Function When performing connection work by replacing the connector to be connected with another type, select a piece member with a retaining groove that matches the shape and size of the connector to be connected,
While fixing this to the upper part of the nest member, move and adjust the position and spacing of each nest member to match the position and spacing of each press rod, and then fix it at the predetermined position. good.
