Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield connector suitable for handling high frequency signals.

[0002]

2. Description of the Related Art In a conventional shielded connector, a metal shield plate that covers four side surfaces of an insulating housing is generally made of a single metal plate, as described in, for example, Japanese Unexamined Patent Publication No. 9-237655. , It is fixed to the insulating housing by push-in adhesion.

[0003]

The shield plate of this conventional shield connector is formed by bending a single metal plate into a tubular shape. In this structure, the parts are easily entangled with each other and the alignment is poor, so the assembly by the automatic machine is not good.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a shield connector which has good shield plate removal and is suitable for automatic assembly.

[0005]

In order to achieve the above object, in the shielded connector of the present invention, four side surfaces of the insulating housing of the connector are covered with a pair of L-shaped shield plates. As a result, the shield plate can be removed easily, and a shield connector suitable for assembling an automatic machine can be obtained.

Further, a fitting protrusion is provided on each of the four side surfaces of the insulating housing of the connector, and a fitting cut groove is provided on each of the shield plates so as to correspond to the fitting projection. Is fitted to the fitting projection, a shield connector having a reliable engagement force between the shield plate and the insulating housing can be obtained.

Further, if the fitting projection is provided with fitting grooves on both sides of which the fitting cut grooves of the shield plate can be dropped and assembled from above the insulating housing,
It is possible to obtain a shield connector in which the engaging force between the shield plate and the insulating housing is more reliable and which is easy to assemble.

Further, the pair of L-shaped shield plates are
If they have the same shape, the shield plate can be removed easily and the manufacturing can be facilitated.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a shield plate used for a shield connector according to an embodiment of the present invention.
The first shield plate 1 is composed of a side plate 2 and an end plate 3 which is integral with the side plate 2 and is substantially L-shaped. Each of the side plate 2 and the end plate 3 is provided with a rectangular fitting cut groove 2a, 3a having an open lower end, and the end plate 3 has a mounting piece on a substrate extending from the periphery of the fitting cut groove 3a. 4 is formed perpendicular to the surface of the end plate 3. Here, the attachment piece 4 is formed so as to project in a loop shape. This is for maintaining strength and ensuring a wider surface, but two projecting pieces separated in the center may be used.

The second shield plate 5 has the same structure as the first shield plate 1 here. As shown in FIG. 1, the L-shaped first and second shield plates can form a rectangle that covers a side surface of an insulating housing (FIG. 2), which will be described in detail later.

FIG. 2 is a perspective view of the insulating housing 6 to which the shield plates 1 and 5 of FIG. 1 are attached. The insulating housing 6 is made of a resin material or the like, has an opening 7 having a large number of grooves into which metal terminals (not shown) are inserted, and is composed of a pair of side walls 8 and 9 and a pair of end walls 10 and 11. Has been done. Fitting protrusions 12 a and 12 b are provided on the side wall 8 and the end wall 10. Although not visible in FIG. 2, the side wall 9 and the end wall 11 are also provided with fitting protrusions 12c and 12d.

FIG. 3 is an enlarged view of the fitting protrusion 12a. In this embodiment, the other fitting protrusions have the same shape. Fitting grooves 13 are provided on both sides of the fitting protrusion 12a, and the fitting cut grooves 2a of the shield plate are fitted therein. The respective fitting cut grooves are fitted into the fitting grooves of the other fitting protrusions.

The first shield plate 1 is assembled to the insulating housing 6 shown in FIG. 2 so that the fitting cut grooves 2a and 3a fit into the fitting projections 12a and 12b, respectively, and are dropped from the upper side. You can The second shield plate 5 can be assembled in the same manner by dropping it into the insulating housing 6 from above. Therefore, it is easy to assemble the shield plates 1 and 5 with the automatic assembling device.

FIG. 4 shows a perspective view of the shield connector 30 after the assembly. FIG. 4 shows a state in which the first and second shield plates 1 and 5 are assembled.

According to the shield connector of the above embodiment, the shield plate is covered with the pair of L-shaped shield plates on the four side surfaces of the insulating housing of the connector. By eliminating the entanglement of the plates, it is possible to easily handle the parts such as alignment, transportation, and packaging, and it is possible to obtain a shield connector suitable for assembly of an automatic machine. In addition, the fitting cut groove and the fitting groove of the fitting projection enable drop assembly, which makes the assembly easier, and a shield connector having a reliable engagement force between the shield plate and the insulating housing.

[0017]

As described above, by covering the four side surfaces of the insulating housing of the connector with the pair of L-shaped shield plates, the shield plate can be removed easily, and a shield connector suitable for assembly can be obtained. be able to.
