Description

[Detailed Description of the Invention] This invention relates to a tab receptacle, and more specifically, to a tab receptacle that is easy to attach to a housing and has increased strength on the tab side.

In general, a plug-in type electrical connector consisting of a tab and receptacle is fixed by caulking or screwing the tab side to an insulating board, and then is attached to the end of the wire or the receptacle is inserted into this tab. The structure is such that a tab attached to the end of an electric wire is inserted into the housing, and a tab attached to the end of the electric wire is inserted into the housing. It was designed to be attached by soldering.

Therefore, there are drawbacks such as a large number of work steps required to attach the tab or receptacle to the insulating substrate or housing, and furthermore, it is not possible to connect the tabs or receptacles in series using the same member, and the applications are limited.

This invention aims to eliminate the above-mentioned drawbacks, and its feature is that the second tab piece is attached to one side of the first tab piece by folding it in half to form a tab. a first contact piece formed at the end of the first tab piece; first and second bearing pressure pieces extending in connection with both ends thereof; and a first contact piece formed at the end of the first tab piece; A second contact piece is provided at an end and faces the first contact piece at a constant distance, and both of the elastic pressure pieces are curved so that the end surface thereof is placed outside the second contact piece. The present invention provides an insertable tab receptacle in which receptacles are formed so as to face near the side ends of the side surfaces, and locking claws projecting outward are cut and raised on the tab pieces.

An embodiment of this invention shown in the drawings will be described in detail above.

As shown in FIG. 1, the tab receptacle of this invention is made by punching and bending a thin sheet of conductive metal such as copper, brass, or cupronickel.

Its structure is such that a first tab piece 1 and a second tab piece 2 of equal length are connected around a bending line 3 shown by a broken line, and
At the end of the tab piece 1, a first piece having a width slightly narrower than the tab piece width is attached.
A second contact piece 4 of the same width extends from the end of the second tab piece 2, and a first contact piece 5 of the same width extends from the end of the second tab piece 2.
and second introduction protrusions 6, 7 are formed.

In addition, the first tab piece 1 has a U-shaped notch with a locking pawl 8 cut and raised, and furthermore, a V-shaped notch is formed on both sides at the connecting portion of the first and second tab pieces. 10a and 10b are provided.

Furthermore, bearing pressure pieces 11a, l are provided on both side edges of the first contact piece 4.
lb is extended, and notches 12a, 12b, 13a are formed on both side edges at approximately the center in the length direction of each bearing pressure piece.
13b is formed.

The material punched into this shape is shown in Figure 2a.

As shown in b, first, the second tab piece 2 is folded in half along the bending line 3 so as to come into contact with the side surface of the first tab piece 1, and the locking claw 8 is raised.

Next, the first and second contact pieces 4 and 5 are bent along bend lines 14a and 1 so that a gap equivalent to the thickness of the material is formed between them.
4b, 15a, and 15b are bent into a crank shape so that they face each other, and the introduction protrusions 6 and 7 are each inclined outward so as to form an inverted U-shape.

Furthermore, notches 12a and 12b of bearing pressure pieces 11a and llb
, 13a, 13b are formed on the bending line 16b
, 16 c, 17 b, and 19 c sections are formed on the bent side of the second tab piece 2 to form a substantially U-shape, and after forming a recess on the bent surface side, first apply the bearing pressure at the bending lines 16 a and 17 a. Fold the pieces 11a and llb outward, and line the bending lines 16a, 16b, 17a, 17b and 16c, 16d.
and 17c and 17a are bent into a semi-arc shape having a radius equal to the length of , and the end surfaces of both of the bearing pressure pieces are opposed to each other slightly inwardly from both side edges of the second contact piece 5. and the second
A contact piece is inserted between the contact pieces, and when both contact pieces open outward, they come into contact with each other and bear pressure.

The tab receptacle of this invention is constructed as described above, and since it is symmetrical as shown in Figure 3,
As shown in Figures a and b, this tab receptacle 1 is inserted into the insertion hole 20 formed in the common bottom 29 between the symmetrically made tab side hole 27 and the receptacle side hole 28 of the mounting housing 26. When inserted, the crank-shaped bent portion formed between the first and second contact pieces and the first and second tab pieces is inserted into the receptacle side hole 27 of the bottom part 29, and the locking pawl 8 is inserted into the hole. After passing through 20, it returns to its original state and is locked to the six tabs on the bottom 29 to maintain the mounted state.

As described above, this invention includes a second tab piece that is folded in half and attached to one side of the first tab piece to form a tab, and a second tab piece that is formed at the end of the first tab piece. a first contact piece, first and second bearing pressure pieces that extend in connection with both ends thereof, and are located at an end of the second tab piece and spaced apart from the first contact piece by a certain distance. and a second contact piece facing each other, and both of the elastic pressure pieces are curved so that the end face thereof is connected to the second contact piece.
The noceptors are formed so as to face near the side edges of the horizontal plane of the contact pieces, and locking claws that protrude outward are cut and raised on the tab pieces, so the tabs are strong and strong when inserted into the connector. Also, since the contact piece is regulated in its spreading direction by the bearing pressure piece, the specified pressure contact force can always be maintained no matter how many times the contact piece is inserted, resulting in high reliability. Since there are no holes, it is easy to mass produce and can be assembled at a low cost. Furthermore, since the housings are assembled symmetrically, there is no need to change the direction indicator 1 when inserting the housing, so automatic assembly is possible.
