A device is provided which is arranged to be movable linearly towards said connector receiving member for each push into a slot.

The device according to the invention, in contrast to known devices used for the same purpose, requires only two combs to insert all the wires at the same time, and each slot in each comb has two groups of wires. , and the contacts of the connector are disposed intermediate the two groups of wires.

An embodiment of the device according to the invention will be described below with reference to the accompanying drawings.

Referring to FIG. 1, a connector 1 includes a housing 2 of insulating material having two rows of passages 3 therethrough.

The passages 3 each accommodate an electrical contact 4. Each contact 4 has a contact portion 5 located in a slot 6 of the housing 2, so that conductors provided on both sides of the edge of a printed circuit board (not shown) can be inserted into the slot 6 to make contact. The contact portion 5 of the child 4 can be contacted.

Furthermore, each contact 4 has a connecting part 7 to which it connects an electric wire 8.

The connecting part 7 contains a pair of parallel and spaced apart plates, each plate having a slot 9.

The contacts 4 are arranged in one row on each side of the central protruding wall portion 10 of the housing 2 .

The slots 9 of the contacts 4 are located in the opposite direction from the slots 9 of the contacts 4 of one row to the slots 9 of the contacts 4 of the other row.

In other words, the slots 9 of the contacts 4 all face away from the wall 10 of the housing.

Both ends (only one end shown) of the housing 2 have flanges 11, each flange 11 having a boss 12 provided with a bore for receiving a bolt to secure the connector to another element.

Referring now to FIGS. 2-4, the device according to the invention includes a connector receiving member 13 having two comb portions 14 secured thereto by bolts 15. As shown in FIGS.

The comb portion 14 has a plurality of aligned pairs of slots 16 located on either side of the connector 1 housed within the member 13.

Slots 16 are arranged to receive conductors, such as wires 8 (FIG. 1), and each wire 8 is connected to a contact 4 of connector 1.
with corresponding pairs of slots 9 in the .

The device also includes a first insert member 17 and a second insert member 18 located on either side of the connector receiving member 130.

Each insertion member 17 , 18 has a support member 19 and an insertion tool 2
0, and the insertion tool 20 is attached to the support member 19 by bolts 21.

The insertion tool 20 includes a tooth member 22 whose teeth serve to force the wire into the slot 9 of the contact 4 of the connector 1, as will be explained later.

Support member 1 of the first insert member 17 shown on the lower side of FIG.
9 has an outwardly extending flange 23, thus giving the member 17 a relatively large underside area so that the device can be mounted, for example, on the platen of a bench press (not shown).

The insert member 17.1B and the connector receiving member 13 are mounted on a pair of rods 24.25.

The rod 24.25 is fixed in a bore 26 of member 17 and slidably received in a bushing 27 carried at each end of member 13.18.

Compression springs 28 are arranged on rods 24.25 between members 13 and 17 and between members 13 and 18.

The member 18.13 therefore resists the action of the spring 28 on the rod 24.
, 25 towards member 17.

As clearly shown in FIG. 3, rod 24 is longer than rod 25 so that when member 18 is in the raised position as shown in FIG. 25
The connector accommodating member 13 can be easily accessed.

To prevent the member 18 from coming off the rod 24,
A collar (not shown) can also be attached to the free end of the holder.

The device described above is used as follows.

First, member 18 of the device is rotated about rod 24 as described above to expose member 13.

Next, the electric wire 8 is arranged so as to cross each aligned slot 16 of the comb portion 14, and
be located at the bottom of the

The electric wires arranged in this manner constitute a first electric wire group.

As shown in FIG. 2, the electric wire 8 may be an electric wire of a multi-core cable 31.

Next, both flanges 11 of the housing 2 of the connector 1 are inserted into the recess 29 of the connector receiving member 13, and the connector 1 is placed on the member 13.

When the connector 1 is installed as described above, the slots 9 of the contacts 4 of the connector 1 are aligned with the slots 16 of the comb 14 and thus with the wires 8 disposed within the comb 14.

Next, the electric wires 8 of the second electric wire group are connected to the comb portion 1 as shown in FIG.
When inserted into the slot 16 of connector 1, the wire 8 is inserted into the slot 16 of connector 1.
The slot 9 of the contact 4 is aligned with the slot 9 of the contact 4.

The member 18 is then returned to the position shown in FIG. 2, with at least a portion of the rod 25 being received within the boss 27 on the right end of the member 18 as seen in FIG.

As is clear from FIGS. 2 and 4, when the connector 1 and the wire 8 are arranged on the device as described above, the wall 10 of the housing 2 of the connector 1 is located on the left side of the member 13 as seen in FIG. A slot 30 formed between the comb portion 14 and the comb portion 14 located therein.
The connecting part 7 of the contact 4 which extends upwardly and is therefore located on the wall 10 can be accessed from above and below the slot 30.

The apparatus is then positioned such that the underside of flange 23 of member 17 is positioned over the platen of a press (not shown) and the ram of the press is aligned with the centerline of member 18.

The press is then actuated to push the insert member 18 along with the connector receiving member 13 down towards the insert member 17, and while such movement is performed, the member 17.
An insertion tool 20 held by 18 engages the wire 8 and forces it into the slot 9 of the corresponding contact 4.

The tool 20 on member 17 inserts the wires 8 of the first wire group into the slots 9 of the contacts 4 of the lower row as seen in FIGS. The wires 8 of the second wire group are inserted into the slots 9 of the contacts 4 in the upper row as seen in FIGS. 2 and 4.

As clearly shown in FIG. 4, the insertion tool 20 held by the member 17 includes the member 13 and the comb portion 14 located to the left of the member 13.
It engages with the electric wire 8 through the slot 30 between.

While the wire 8 is being pushed into the slot 9, both edges of the slot 90 penetrate the insulation of the wire 8 by a known method;
Contact with core wire.

When the ram of the press completes its downward movement and returns to its raised position, the spring 28 pushes the member 13.18 upwards away from the member 17 as well, so that the member 18 continues to move around the rod 24 and into the rod 25. rotated away from the

Therefore, the connector 1 to which the electric wire 8 is connected can be taken out from the device.

As is clear from the above description, the device described above does not cut the wire 8 in any way, so that the connector 1 can be used to connect the wire 8 at any position on the wire 18.

However, the device can be easily modified so that the terminal of the wire 8 can be cut and a connector can be connected to the terminal.

To achieve this purpose, a cutting member (not shown) having a pair of cutting blades and surrounding the connector is mounted on the connector receiving member 13.

The cutting blades extend on both sides of the wall 10 of the housing 2 between the connecting part 7 of each contact 4 and the main body part of the housing 2.

The cutting blade is arranged so that the inner edge of the insertion tool 20 can pass in close proximity to the cutting blade, and in this case the inner edge of the insertion tool 20 is not sloped as shown in FIG. 4, but is rather square. .

Therefore, when pushing the wire 8 into the slot 9 of the contact 4, the wire 8 is cut between the inner edge of the insertion tool 20 and the cutting blade of the cutting member.

After the cutting member is subsequently removed from the device together with the connector and the wire, the cutting member is removed from the connector.

The connector is thus connected to the end of the wire.

The following examples can be further considered as embodiments of the present invention.
