Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield connector for a device which is mounted on a device.

[0002]

2. Description of the Related Art Conventionally, as a shield connector for a device for connecting a plurality of shielded wires to an inverter device in an electric vehicle, a mounting hole is opened in a conductive shield case and a device-side terminal mounted on the inverter. Facing the mounting hole, the wire-side terminals fixed to the ends of each shielded wire, respectively, are set in the mounting holes and connected to the device-side terminals, and the terminal portion of the shield member of each shielded wire, Each has a structure connected to a shield case. However, in this shield connector for equipment, the operation of setting the electric wire side terminal and the operation of connecting the shield member to the shield case must be repeated as many times as the number of shielded electric wires, which is troublesome.

Therefore, a plurality of unshielded electric wires are collectively surrounded by a cylindrical shield member, and the electric wire side terminals are fixed to the ends of each electric wire, and the plural electric wire side terminals are collectively attached to the housing. Further, a structure is conceivable in which a shield shell is fixed to a terminal portion of the shield member, and the shield shell is externally fitted to the housing. In this way, if a plurality of wire-side terminals are integrated in advance and one shield shell surrounds the plurality of wire-side terminals collectively, a plurality of wire-side terminals can be collectively mounted at the time of installation. The shield shell can be connected to the shield case only once.

[0004]

In the above-mentioned shield shell, it is necessary to form a cylindrical portion fitted to the housing and a flange portion to be attached to the shield case. The shield shell having such a shape is a general manufacturing method, that is, a relatively thin flat plate material is subjected to a deep drawing process by pressing, so that a thin cylindrical portion is beaten out from a flange portion. It is possible to mold by such a method.

[0005] However, it is difficult to form the cylindrical portion into a complicated shape by deep drawing, and it is unavoidable that the cylindrical portion has a substantially cylindrical shape without any irregularities or catching. It is difficult to firmly integrate the two simply by externally fitting the cylindrical portion having such a small body shape to the housing. Therefore, as a countermeasure, it is conceivable to form the cylinder part smaller and fit it tightly to the housing. However, even if it is tightly fitted in this way, the thin tubular part can withstand press-fitting. Since it is not possible to expect the rigidity to be obtained, there is a concern that the diameter of the cylindrical portion is expanded and deformed due to the action of external force or interference of foreign matter, and as a result, the shield shell comes off the housing.

The present invention has been made in view of the above circumstances, and has as its object to securely assemble a shield shell and a housing.

[0007]

According to a first aspect of the present invention, a plurality of equipment-side terminals are connected to an equipment having a plurality of equipment terminals fixed in a shield case. And a plurality of wire-side terminals enabled to be connected to the device terminal, and fixed to a terminal portion of a shield member surrounding the plurality of wires collectively, thereby enabling connection to the shield case. And a housing for holding the electric wire side terminal, wherein the shield shell has a higher rigidity than the housing, and the shield shell is externally fitted to the housing.

According to a second aspect of the present invention, in the first aspect, the shield shell is made of metal, the housing is made of synthetic resin, and the shield shell is fitted to the housing by press fitting. . According to a third aspect of the present invention, in the second aspect, a convex portion is provided on at least one of an outer peripheral surface of the housing and an inner peripheral surface of the shield shell, and the convex portion is provided on a peripheral surface of a mating side. And press-fitted.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the convex portion has a rib shape extending along the press-fit direction of the housing and the shield shell, and a peripheral portion corresponding to the convex portion is provided. A groove-shaped concave portion extending in the press-fitting direction is formed on the surface, and the convex portion and the concave portion are fitted at the time of press-fitting. According to a fifth aspect of the present invention, in the first aspect of the present invention, the housing causes the wire-side terminal to protrude from a terminal protruding end and a direction substantially perpendicular to the terminal protruding direction from the wire lead-out end. The shield shell has a fitting hole for restricting the housing from floating by fitting the wire lead-out end, and leading the wire substantially parallel to the outer surface of the shield case. A terminal protruding opening that opens toward the outer surface of the shield case and protrudes the wire-side terminal to the outside of the shield shell, and communicates with the terminal protruding opening, with respect to the outer surface of the shield case. A housing fitting opening which is opened so as to correspond to the vicinity is formed.

[0010]

According to the first aspect of the present invention, since the shield shell has a higher rigidity than the housing, the shield shell does not come off the housing due to deformation of the shield shell. The shield shell can be securely assembled. As a method for forming the shield shell, there are a method by die forming and a forging method. Further, the material of the shield shell is not limited to metal, but may be a conductive resin material.

[Invention of Claim 2] Since the metal shield shell is sufficiently higher in rigidity than the synthetic resin housing, the shield shell is not deformed even by press-fitting.
The shield shell and the housing can be firmly assembled by the friction caused by the press-fitting. [Invention of claim 3] Since frictional resistance due to press-fitting occurs between the housing and the shield shell only at the portion where the convex portion is formed, the resistance at the time of press-fitting is small.

[Invention of claim 4] By providing a concave portion to be fitted with the convex portion on the other side of the convex portion, the convex portion and the concave portion are
It exerts the function of positioning in the circumferential direction between the housing and the shield shell. That is, since the convex portion which exerts the press-fitting function also has the positioning function, the shapes of the housing and the shield shell can be simplified as compared with the case where a dedicated positioning function portion is provided separately from the convex portion. [Invention of claim 5] Since the projecting direction of the wire side terminal and the lead-out direction of the wire are perpendicular to each other, and the wire is led out along the outer surface of the shield case, it can be provided even in a narrow space. it can. In addition, since the housing fitting opening is communicated with the terminal projecting opening, a large opening for fitting the housing into the shield shell is secured, so that the housing can be easily fitted into the shield shell. Further, in the housing insertion opening, the shielding function of the shield shell is not exhibited, but since the housing insertion opening is provided so as to be close to and correspond to the outer surface of the shield case, In the housing fitting opening, a shielding function is exerted by the shielding case. Therefore, there is no need to attach a separate shield component to the shield shell for closing the housing fitting opening.
