Description

[Detailed Description of the Invention] (Subject of the Invention) The present invention is a cable end face assembly component that is easy to assemble into a modular plug and has electromagnetic wave shielding measures.

(Prior Art and its Problems) Conventionally, in a modular plug for electromagnetic shielding as shown in FIG. 5, a shielded cable 1 is stripped as shown in FIG.

That is, the sheath 1a and the shield material 3 are cut at different lengths. Thereafter, as shown in FIG. 7, the shield material 3 and the drain wire 4 are folded back and an alignment tube 9 is fitted to prevent the wire 2 from coming apart. Next, as shown in FIG. 8, the procedure is to fit it into the plug housing. Finally, the metal shell 7 and the ferrule 5 are placed over each other to establish electrical continuity, resulting in a completed product as shown in FIG.

By the way, in this step, not only was the work of folding back the shield material 3 difficult, but also the end face after folding was not neat. This was particularly noticeable when the sheath was braided. For example, Utsukai 59-
The article known in Publication No. 198675 had such drawbacks.

(Purpose of the invention) In order to solve the above-mentioned drawbacks, the present invention was made for the purpose of providing a grounding terminal that does not require folding back the shield material 3 or the drain wire 4. The invented ground terminal has a shielding material 3 on the outside of the cable sheath 1a.
Alternatively, a common head 8c is provided in place of the conventional alignment tube 9 for aligning a plurality of wires 2 while making them conductive to the drain wire 4.

(Configuration of Embodiment) Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 4 shows the shape of the ground terminal 8 of the present invention, which is pressed from a highly conductive metal plate. As is clear from the front view and development view, the shape of the ground terminal is a common head 8c forming a long slit 8d.
It consists of two legs 8a and 8b that come out from.

FIG. 1 is a perspective view of a state in which the sheath 1a and the shield material 3 or the drain wire 4 at the end of the cable 1 are cut off at the same part and the ground terminal 8 of the present invention is incorporated.

FIG. 2 is a plan view and a front view corresponding to FIG. 1.

Figure 3 shows the legs 8a and 8b of the ground terminal in Figure 2.
The assembly position is shown. That is, foot 8a
are inserted so as to contact the shield material 3 or the drain wire 4, and the legs 8b are arranged on the outside of the sheath 1a.

Further, the wires 2 are fitted into the common head 8c of the ground terminal 8 and aligned.

(Other Modifications) Up until now, we have explained the example in which the legs 8b go around once, but it is also possible to have a shape in which continuous legs 8b are separated in the middle, or in which the number of legs 8a and 8b is increased. do not have. In short, it is necessary that 8a and 8b are electrically connected, and it goes without saying that the shape is not limited to the shape described so far, and includes various modifications within the scope of the present invention.

(Effects of the invention) As explained above, the ground terminal 8 of the invention has the excellent effect of being not only simple but also inexpensive to process by simply bending a single metal plate. There is no need to fold back the shield material 3 or drain wire 4, which was conventionally done, and the shield material 3 or drain wire 4 can be placed on the outside of the sheath 1a.
Provide electrically conductive parts.

In addition, the common head 8c can replace the alignment tube 9 for aligning the plurality of wires 2, which can kill two birds with one stone, so it has great industrial value.

Claims (1)

[Scope of utility model registration request] It is made of a single highly conductive metal plate and has legs 8a and 8b protruding from a common head 8c forming an elongated hole 8d, and is inserted so as to make contact with the shielding material 3 or drain wire 4 inside the cable. The earth terminal has a structure consisting of the above-mentioned 8b arranged on the outside of the cable sheath 1a of the above-mentioned 8a and the above-mentioned common head 8c provided for aligning a plurality of wires 2 in the cable.
