Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to, for example, a method of peeling a stripped wire before connecting terminals of each coated wire of a multi-core cable to each terminal provided in a connector at a time. The present invention relates to a method of pre-connecting a covered electric wire to a connector when performing processing and connecting the terminals collectively to each terminal provided in the connector.

[Prior Art] FIG. 2 shows an example of a connector 2 to which a plurality of shielded insulated wires 1 are connected. The connector 2 is provided with a plurality of lead patterns 4 on a printed circuit board 3, and each terminal 5 formed of a printed pattern is provided at the tip of the lead pattern 4 so that the interval between them is constant.
And a collective ground pattern 6 is provided on the printed circuit board 3 in a direction parallel to the row of the terminals 5. Before the shielded coated electric wire 1 is connected to the connector 2, the shield layer 8, the insulating layer 9, and the core wire 10 are sequentially exposed stepwise from the insulating coating 7, and each of the exposed shield layers 8 Each core wire 10 is subjected to a pretreatment for preliminary soldering.

Conventionally, such a pretreatment is performed by using a shielded covered electric wire in each tooth groove of a comb-shaped pretreatment core array jig having a tooth groove having a pitch corresponding to the pitch of each terminal 5 provided in the connector 2. 1 was inserted and arranged. By doing so, the pitch of each shielded coated electric wire 1 that has been preprocessed on the preprocessing core array jig matches the pitch of each terminal 5 provided on the connector 2. The insulated wire 1 can be connected to each terminal 5 provided on the connector 2 in a lump. In this case, the respective shield layers 8 are connected by collectively soldering on the collective ground pattern 6. Each core 10 is connected to each terminal 5 by soldering.

[Problems to be Solved by the Invention] However, in the pretreatment method using the pretreatment core array jig having the tooth grooves with the pitch corresponding to the pitch of each terminal 5 provided in the connector 2, When the pitch of each terminal 5 provided on the connector 2 is large, the pre-processing operation can be easily performed. However, when the pitch of each terminal 5 provided on the connector 2 is small, the adjacent shielded covered electric wire 1 hinders. Thus, there is a problem that the pre-processing work becomes difficult. Conversely, if a pretreatment core array jig having a wide tooth groove pitch is used, the pitch of each shielded electric wire 1 does not match the pitch of each terminal 5 provided on the connector 2, and each shielded coated wire 1 does not match. Collectively connect wires 1 to connector 2
In this case, there is a problem that the work of connecting to each terminal 5 provided in the terminal cannot be performed. Further, in the conventional case, there has been a problem that various kinds of pretreatment core array jigs and pretreatment mechanisms having tooth groove pitches corresponding to the terminal pitch of the connector are required.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of pre-processing a covered electric wire for attaching a connector, which can easily perform a pre-processing operation irrespective of the pitch of each terminal provided in the connector.

[Means for Solving the Problems] The means of the present invention for achieving the above object will be described. The pretreatment method for attaching a covered electric wire to a connector according to the present invention is suitable for pretreating a plurality of covered electric wires. In the state of being arranged in the pretreatment core array jig at the pretreatment arrangement pitch, the process is sequentially transferred to various pretreatment steps to perform the pretreatment work, and the preprocessed coated electric wire is connected to the connector after the completion of the pretreatment work. It is characterized in that it is rearranged to a connector-attached core wire arrangement jig having an arrangement pitch that matches the arrangement pitch of the terminals provided.

[Operation] As described above, when each of the coated electric wires is sequentially arranged in the pretreatment core array jig at a pretreatment arrangement pitch suitable for the pretreatment and sequentially moved to various pretreatment steps to perform the pretreatment work, Various preprocessing operations can be performed using the preprocessing core array jig having the same preprocessing array pitch regardless of the wire size. Therefore, various pre-processing mechanisms can be simplified, and the pre-processing operation can be performed in a state where the core wires are easy to operate without being affected by the pitch of each terminal provided in the connector. Further, the types of the pre-processing core array jig can be reduced, and the types of the respective pre-processing mechanisms can be reduced.

Further, in the present invention, after the pre-processing work is completed, the wires are rearranged into the connector attaching wire array jig having an arrangement pitch matching the arrangement pitch of the terminals provided on the connector, so that each coated electric wire is provided on the connector. Can be correctly arranged at an arrangement pitch that matches the arrangement pitch of each terminal, and each coated electric wire can be correctly connected collectively to each terminal provided on the connector, thereby preventing occurrence of connection failure. .

Furthermore, in the present invention, each terminal is not connected to each coated wire in advance, and each terminal is provided in advance on the connector side. Therefore, the arrangement pitch of each coated wire can be reduced to near the diameter of these coated wires as necessary. The connector can be made narrower, and even if the number of each coated electric wire is large, the enlargement of the connector can be avoided as much as possible.
