Description

[Detailed description of the device]

[0001]

[Industrial applications]

  This invention is a modular type multi-core connector plug structure, more specifically , Provide a mechanism to temporarily fix the electric wire attached to the plug to facilitate the pressure welding work. The present invention relates to a plug structure of a modular type multi-core connector.

[0002]

[Prior art]

  Conventionally, for example, modular type used as an interface for electronic devices Multiple wire insertion holes for multi-core connector plugs (hereinafter referred to as "connector plugs") When a plurality of electric wires are individually pressure-welded to the contact members arranged on the First, the worker aligns these wires and connects the aligned wires to the connector. Insert it into the wire insertion hole of the plug and press it into the contact, or Insert the wires aligned in this way into the wire insertion holes of separate alignment parts, and then insert this into the connector. After mounting on the plug, I had to press the contact.

[0003]

[Problems to be solved by the device]

  In this way, multiple wires are pressed into the contacts of a conventional connector plug of this kind. To make contact, the operator must first line up the wires and then Since it is put in the wire insertion hole, not only is the work troublesome, but also until the wire is pressure-welded. The wire may escape from the wire insertion hole of the connector plug, or There were many problems such as not being able to completely insert the electric wire.

[0004]

[Means for Solving the Problems]

  In consideration of the above-mentioned problems, this invention temporarily fixes the electric wire to the connector plug. A mechanism is provided to hold the aligned electric wires in this temporary fixing mechanism and press-connect What provides a connector plug with a structure that prevents the electric wire from coming out Is.

[0005]

【Example】

  A preferred embodiment of the present invention will be described in detail with reference to the drawings. As shown in Figure 1. As described above, the plug 10 of the modular type multi-core connector is made of an insulating plug body 1 2 and a hood 14 attached to this body.

[0006]   As shown in FIG. 2, the multi-core cable 18 including a plurality of electric wires 16 is used for the hood 14. Is inserted through the opening 20 at one end of the As shown in FIG. 3, the plurality of electric wires 16 exposed from the ends are connected to the plug of the plug body 12. The length of the plug body 12 passes through the wire insertion space 22 in which the bottom of the plug side 14 is open. In the electric wire insertion hole 24 that extends in the axial direction and the end opposite to the hood 14 is closed Is inserted. As shown in FIG. 4, each wire 16 is at the tip of the wire insertion hole 24. , Is connected to a contact member 26 that is press-fitted from the bottom of the plug body 12.

[0007]   Insert the wire 16 into the wire insertion hole 24 through the wire insertion space 22 of the plug body 12. Then, attach the contact member 26 from the bottom of the plug body 12 to the tip of the electric wire 16. Push it in, press it against the wire 16, and fix the wire 16 to the plug body 12. Until then, temporarily fix the wire 16 so that it will not come out of the plug body 12. Therefore, according to the present invention, the wire insertion space in which the bottom of the plug body 12 is opened. 22 is specially provided, and in order to hold the electric wire 16 exposed at this portion, a temporary electric wire is provided. A stop block 28 is provided.

[0008]   This electric wire temporary block 28 is provided at the front end of the electric wire insertion space 22 of the plug body 12. From the state where it is suspended below the side wall of the wire (Figs. 1 and 2), In order to move the open bottom to the closed state (Fig. 4), the plug body 12 and the It is attached to the body at a hinge portion 30. Block 28 for temporarily fixing electric wire So that it can be fixed to the plug body 12 when Projecting portion 32 is formed, and on the other hand, the corresponding side wall of the cavity 22 of the plug body 12 A recess 34 for receiving the locking projection 30 is formed in the portion. Furthermore, this When the vacant space 22 is closed by the electric wire temporary block 28, For temporarily fixing the wire so that the part of the wire 16 inserted in the wire insertion hole 24 is held. A protrusion 36 for holding an electric wire is provided on the inner surface of the block 28.

[0009]

[Effect of device]

  So that you can fully understand it from the above detailed explanation, According to the plan, the hinge portion 30 is provided on the plug body 12 of the modular type multi-core connector. By attaching the block 28 for temporary wire fixing together, plug multiple wires 16 After inserting into the body 12, attach the contact member 26 to the plug body 12, A block for temporarily fixing the electric wire until the work of pressing the contact member 26 to the wire 16 28 allows the wire 16 to be held in that position. So Therefore, the electric wire 16 may escape from the plug body 12 before the pressure welding work. Further, it is possible to prevent the wire from coming out of the wire insertion hole 24. Shi Therefore, the electric wire 16 is inserted into the plug body 12 of the connector, and the contact member 26 is inserted. It is possible to perform the work of pressure welding with extremely accurate and efficient.
