Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector holding device in a connector pressure welding machine that connects a pressure welding connector to the end of a ribbon cable or a plurality of covered electric wires (discrete wires) cut into a certain length.

A pressure welding device includes a pressure welding punch and a pressure welding die for connecting an end portion of an electric wire to a pressure welding connector, and the pressure welding punch is actuated by a driving means such as an air press; A semi-automatic connector pressure welding machine is equipped with a connector automatic supply device that automatically supplies pressure welding connectors to predetermined positions, and is configured to manually arrange ribbon cables or covered electric wires (discrete wires) to be connected. It is necessary to fix and hold the supplied press-connecting connector in a press-fitting position, and after the press-fitting work is completed, to release the fixed holding and discharge it. In addition, it is necessary to arrange the ends of the ribbon cable or multiple covered wires (discrete wires) to be connected to correspond to each contact of the pressure welding connector, but in particular, when using discrete wires where each wire is independent, When arranging in a pressure welding position directly under the punch in a narrow free space, it is not only difficult to arrange the arrangement, but it is also extremely dangerous if the pressure welding punch operates unexpectedly. It is desirable to perform the arranging work by moving the wires to a wire arranging position spaced apart from the pressure welding position.

In order to provide the connector pressure welding machine with the above-mentioned functions, the present invention automatically fixes and holds the pressure welding connector supplied to the pressure welding position, and when the pressure welding die is moved to the wire arrangement position, The present invention provides a connector holding device including a connector holding member that interlocks to release the pressure welding connector fixedly held on the pressure welding die.

Hereinafter, embodiments of the present invention shown in the drawings will be described.

The connector holding device 20 is disposed below the pressure contact position, and is connected to the supply passage 16 by the supply pusher 15.
As shown in FIG. A pressure welding die 8 is configured by being fixedly adjacent to the key 22 via the key 22 . The base block 9 has a wire guide plate 2 provided with a guide groove 24 corresponding to the guide groove 11 of the set block 10 to facilitate the arrangement of the wire ends.
3 is fixed.

The sliding base 21 is provided so as to be slidable along guide plates 25, 25 arranged on the base 1 in a direction substantially orthogonal to the supply passage 16,
By operating the operation plate 27 attached to the rear end plate 26 by an air cylinder or other appropriate device, the pressure welding die 8 is moved from the pressure welding position shown by the solid line in FIGS. 2 and 3 to the imaginary line in FIG. 3 and FIG. It can be moved to the wire arrangement position shown in the figure. Operation panel 27
protrudes downward from an opening 28 provided in the base 1.

Furthermore, a connector holding plate 29 is slidably provided on the sliding base 21 and is disposed opposite to the set block 10 of the pressure welding die 8. The connector holding plate 29 is attached to a sliding block 30 that is slidably disposed between the base block 9 and the rear end plate 26, and the front end 26a passes through an opening 31 formed in the wire guide plate 23. It is located opposite to the set block 10 and is biased toward the set block 10 by the action of a push spring 32 interposed between the sliding block 30 and the rear end plate 26. The pressure contact connector 4 supplied on the base block 9 is fixedly held in cooperation with the set block 10.

Furthermore, a release lever 33 is attached to the sliding base 21 for releasing the press-fitting connector 4 from being fixedly held by the connector holding plate 29 at the wire arrangement position. The release lever 33
As shown in FIG.
is pivotally supported on the sliding base 21 via the
A circular part 35 formed at one end of the sliding block 3
It engages with a recess 36 provided in the side wall of the holder 0, and the other end protrudes 37 outward. Therefore, the sliding base 21
When the pressure welding die 8 is moved from the pressure welding position to the wire arrangement position, the protrusion 3 of the release lever 33
7 comes into contact with a stopper 38 erected on the base 1, the release lever 33 rotates about the pin 34, and the sliding block 30 is moved backward against the push spring 32. In conjunction with the backward movement of the sliding block 30, the connector holding plate 29 is separated from the set block 10 of the pressure welding die 8, and the fixed holding of the pressure welding connector 4 is released.

Next, the effect will be explained. With the sliding base 21 retracted and the pressure welding die 8 moved to the imaginary line in FIG. 3 and the wire arrangement position shown in FIG. Insert each end into the corresponding guide grooves 11 and 24 and arrange them. When the arrangement work is completed, an operating switch of an air cylinder (not shown) connected to the operation plate 27 is operated to advance the sliding base 21 and move the pressure welding die 8 together with the electric wire 40 to the pressure welding position. When the operation switch of the pressure welding machine is turned on in this state, the supply pusher 15 is operated, and the supply passage 16 is

At this time, the pressure contact connector 4 is fixedly held by the connector holding plate 29 which is urged toward the set block 10 by the push spring 32. Subsequently, the pressure welding punch 7 is lowered to connect each end of the electric wire 40 to the pressure contact connector 4.

When the pressure welding work is completed and the pressure welding punch 7 rises and the supply pusher 15 returns to its original position,
The sliding base 21 moves backward to move the pressure welding die 8 to the wire arrangement position. In conjunction with this backward movement, the release lever 33 is operated as described above, and the connector holding member 29 is separated from the set block 10 of the pressure welding die 8. As a result, the press-fitting connector 4 connected to the end of the electric wire 40 is released from being fixedly held, and can be easily taken out.

As explained above, the connector holding device of the present invention automatically fixes and holds the pressure welding connector supplied to the pressure welding position, and when the pressure welding die is moved to the wire arrangement position, the connector holding device of the present invention automatically holds the pressure welding connector fixed. Since it is designed to release the fixed hold,
The fixed holding and release operations of the pressure welding connector are extremely reliable, and at the same time, the arrangement of the electric wires and the ejection of the pressure welding connector to which the wires are connected can be easily performed.
