Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a multi-pole connector in which a plurality of pole pieces, which serve as contact terminal poles, are held in a predetermined array on the tip side of a body, which serves as a connecting end. The present invention relates to an insulating device for preventing contact conduction between conductive wires connected to each pole piece.

More specifically, a plurality of pole pieces pulled out from a parent cord inserted from the base end of the body are attached to each base end of a plurality of pole pieces held by a pole holding member attached to the front end of the body. In multi-pole connectors, which are assembled by stripping the core wire and the shield wire that covers the core wire from the child cord and connecting them separately, the shield wires connected to multiple pole pieces contact each other within the body to form a multi-pole connector. The present invention relates to an improvement in insulating means installed in a body to electrically insulate each shield wire from other shield wires in order to prevent the function of the connector from being impaired.

2. Description of the Related Art As shown in FIG. 1, a multi-pole connector A normally has a pole holding member b formed from an insulating material in the shape of a plug attached to the distal end side of a body a serving as a connector main body. A plurality of pin-shaped or sheath-shaped pole pieces c made of a metal material with good electrical conductivity are arranged and held in a predetermined arrangement state, and each base end of the pole pieces c is The core wires 10 of cord d inserted from the base end side of body a and the shield wires 11 covering these core wires 10 are distributed and connected according to a predetermined arrangement, and the cord d is connected. The proximal end of the end is caulked to the proximal end of body a by an appropriate clamping means, and if body a is formed of a metal material, the outer periphery of the body a and the proximal end of the connecting end of cord d are caulked. A cover e formed of an insulating material is fitted around the outer periphery of the insulating material.

[0004] By the way, the cord d used in this multi-pole connector A usually consists of a core wire 10, an inner skin 12 made of an insulating material surrounding it, a shield wire 11 made up of fine wires of a metal material covering the outer periphery thereof, and A plurality of thin cord wires 1 formed with a covering tube 13 made of an insulating material surrounding the outer periphery are bundled together and covered with an outer sheath 20 made of an insulating material.

[0005] When used for multi-pole connector A,
From the connecting end of code d, which is the parent code, its outer skin 2
0 is removed, and first, the child cord cord wire 1... is exposed. Next, the insulating material covering tube 13 is cut off from the end portion of each exposed cord wire 1 to expose the shield wire 11. Next, the exposed end portion of the shield wire 11 is peeled off from the outer periphery of the inner skin 12 and twisted into a string.
A connection end of the shield wire 11 is formed. Next, the end portion of the endothelium 12 is cut off to expose the end of the core wire 10 inside it, thereby forming a connecting end of the core wire 10.

In this state, the terminal portion of cord d, which is the parent cord, is inserted through the open opening at the rear end of body a, and the core wire 10 and shield wire 11 exposed from the cord wires 1, which are each child cord, are connected. Pole holding holes 30 whose ends are connected to the proximal ends of pole pieces c formed in a sheath shape from a metal material, and the pole pieces c are formed in a predetermined array in the pole holding member b. ... and hold it, then pole holding member b
The multi-pole connector A is assembled by fitting and assembling the body a into the body a.

For this reason, when assembled into the multi-pole connector A, the shield wires 11 exposed from each cord wire 1 are connected to the pole piece c and the pole holding hole of the pole holding member b. Due to the margin prepared for the operation of inserting the pole piece c into 30..., the shield wires 11... are positioned with slack in the space inside the body a, and these shield wires 11... come into contact with each other. Inconvenient situations may occur.

[0008] As a countermeasure for this, conventionally, the method shown in Fig. 2
As shown in , at the terminal of the shield wire 11 which is exposed from the cord wire 1 which is the child cord and twisted into a string shape,
A tube w made of a synthetic resin material that shrinks due to heat is placed over the outer circumference of the shield wire 11 by heat treatment, and further,
Covering tube 1 of the proximal end of the tube w and the cord wire 1
By heat-treating the part extending over the terminal part of the shield wire 11 by covering it with a heat-shrinkable tube y of a somewhat large diameter, the connecting end of the shield wire 11 moves inside the body a and connects the adjacent shield. Even if they come into contact with the connecting ends of the wires 11, they are prevented from electrically conducting.

[0009]

[Problem to be Solved by the Invention] In order to prevent conduction failure due to contact between the shielded wires 11 in the body of the multi-pole connector, heat shrinkable material is attached to the outer periphery of the shielded wire 11 exposed from the cord wire 1. As for the means for covering the tubes w and y made of synthetic resin, in order to reliably prevent conduction due to contact between adjacent shield wires 11, the heat-shrinkable tubes w and y must be stacked in two layers as described above. However, there is a problem in that this process is troublesome.

Another method is to incorporate a partition made of an insulating material into the body a, and use the partition to separate the exposed ends of the shielded wire 11 from each other. In this case, another problem arises in that the operation of assembling the insulating partition wall into the body a and the operation of fixing it within the body a become complicated.

The present invention has been made in order to solve these problems occurring in the conventional means, and prevents conduction due to contact between shield wires exposed from the cord wires in the body of a multipolar connector. It is an object of the present invention to provide a new means for easily incorporating a partition wall made of an insulating material into a body and properly assembling and fixing it to the body.

0012

[Means for Solving the Problems] In the present invention, as a means to achieve this object, the shield wires exposed from the plurality of cord wires included in the cord are molded with an insulating material so as to separate them from each other. The bulkhead to be incorporated into the body is integrally or The present invention proposes an insulating device in a multi-pole connector, which is characterized by being integrally connected.

In order to prevent the shield wires 1 exposed from the cord wires 1 of code d from coming into contact with each other in the body a, each shield wire 11 is formed of an insulating material and connected to the wall plate. When a partition h built into a body a so as to be electrically isolated by a cord clamp f is used to bind the outer periphery of a cord d at its proximal end, a partition wall h is installed in a body a so as to electrically isolate the cord d from the plurality of cord wires 1 of the cord d. Since it is integrally or integrally connected to the core g that is fitted into the core of the bundle, the cord d is automatically tightened by tightening the outer periphery of the tip end of the cord d using the cord clamp f. This facilitates the assembly work of the partition wall h.
