Description

[Detailed description of the invention] This invention is a connector contact that mechanically and electrically connects the center conductor of the insulated wire by press-fitting the untreated insulated wire to break the insulation coating. It is related to.

First, the structure of a conventional contact of this kind will be explained with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 denotes a contact made of a conductive plate, and one end of the contact 1 is bent into a U-shape to form a wire connection section. This wire connection part includes a clamping plate 4, 4' having a slit 2, 2' and an inclined part 3, 3' continuing to one end of the slit 2, 2';
A connecting plate 5 connecting the clamping plates 4 and 4' is U-shaped, and the connecting plate 5 is formed with an opening 6 that continues to the inclined portions 3 and 3'. Reference numeral 7 denotes an insulating coated electric wire, which is an electric wire in which an insulating coating layer 9 is formed around the outer periphery of a central conductor 8.

In FIG. 1, when the electric wire 7 is pressed against both the inclined parts 3, 3' of the contact 1, the insulation coating layer 9 of the electric wire 7 is pushed into the inclined parts 3, 3' and the slits 2, 3'.
2', the center conductor 8 of the electric wire 7 is held between the slits 2 and 2', electrical continuity between the center conductor 8 and the contact 1 is obtained, and the electric wire 7
is mechanically fixed.

The conventional contactor described above has sufficient rigidity in the X and Y directions shown in FIG. 2, but has insufficient rigidity in the Z direction. When pressing the contact plate 4,
4' is bent in the directions a and a', which has the disadvantage that the electric wire 7 cannot be sufficiently clamped, and in addition, in order to accommodate various large and small electric wires, it is necessary to use contacts with different slit widths C. .

The present invention eliminates the above-mentioned conventional drawbacks, and an embodiment of the present invention will be described below with reference to FIGS.
This will be explained with reference to FIGS. 4 and 5.

FIG. 3 shows the completed state of the contactor of the present invention. This contactor 10 is formed by punching and bending a single conductive plate. Reference numeral 11 denotes a base plate of the contactor 10, and side plates 12,
12' are integrally formed. Each side plate 1
2, 12' have clamping pieces 13, 13', 14,
14' is formed. This clamping piece 13,1
At the top of 3', 14, 14' are sloped parts 15, 15',
16, 16' are formed. Clamping pieces 13 and 1
4 and between the holding pieces 13' and 14', slits 17, 17' are formed. 18, 18', 1
9, 19' are protruding pieces formed on the base plate 11, and between the protruding pieces 18, 18', the holding pieces 13, 14 are provided.
The lower portions of the clamping pieces 13' and 14' are positioned between the protruding pieces 19 and 19'. 20,
Reference numeral 20' designates contact pieces integrally formed on both sides of the other end of the substrate portion 11, and these contact pieces 20, 2
0' is formed with curved portions 21, 21' that face each other. In FIG. 3, the connection pin (not shown) inserted in the -Z direction is connected to the contact pieces 20, 20'.
The contact pin 10 is held between the contact pins 10 and 10 to establish electrical continuity between the connection pin and the contact 10. The contact 10 is housed in an insulating housing (not shown), and the engaging piece 24 engages within the insulating housing, and the contact 10
is prevented from coming off.

4 and 5 show the process of manufacturing the contactor 10 of the present invention, in which a long conductive plate 22 is punched out,
The contacts 10 are sequentially formed by bending and cutting.

In step a of FIG. 4, unnecessary portions are removed by punching. In step b in Fig. 4, the clamping piece 1
3, 13', 14, 14' are bent,
Projecting pieces 18, 18', 19, 19' are formed.
Furthermore, in step c of FIG. 4, the side plates 12, 12' are bent. By bending the side plates 12, 12', the lower portions of the clamping pieces 13, 13', 14, 14' are located between the protruding pieces 18, 18' and 19, 19'. FIG. 5 shows a side view of FIG. After step c, the necessary portions of the substrate portion 11 are cut to form the contact 10 shown in FIG. 3. Note that in FIGS. 4 and 5, the manufacturing process of the contact piece 20 is omitted.

FIG. 6 shows the contactor 10 of the present invention and the insulated electric wire 7.
This shows the state in which the As shown in FIG. 6, using a jig 23, the electric wire 7 is held between the holding pieces 13 and
3', 14, 14' inclined parts 15, 15', 16,
When the wire 7 is press-fitted into the slits 17, 17' through the wire 16', the insulation coating layer 9 of the wire 7 is torn, and as shown in FIG.
It contacts and is held by the edge of the wire 14', thereby providing electrical continuity between the electric wire 7 and the contact 10, and mechanically fixing the wire 7 and the contact 10.

The present invention has the above configuration, and according to the present invention, the following effects can be obtained.

(1) The lower part of the clamping piece is supported by the protruding piece, so it has sufficient rigidity in the X, Y, and Z directions.
In particular, since the clamping pieces are positioned between the protruding pieces, the rigidity in the Z direction is increased, and the electric wire can be securely welded.

(2) Since the wire is held in two places, the wire will not come off even if external force is applied.

(3) By changing the lengths A and B in FIG. 4, contacts that can be applied to wires of various sizes can be obtained.
