Description

[Detailed Description of the Invention] This invention relates to a tab receptacle, and more specifically, to a double tab receptacle for connecting tabs.

In general, a plug-in electrical connector consisting of a tab and a dove receptacle is attached to the insulating board on the tab side using fixing means such as caulking or screwing, and the tab receptacle attached to the current end is inserted into this tab. The configuration was such that a tab receptacle was housed and fixed in the housing, and a tab with an electric wire attached was inserted into the tab receptacle.

Therefore, even if the tabs and the tab receptacles can be connected, there is no tab receptacle for connecting the tabs, and even if there is, there is no way to mount it inside the housing.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a plurality of tab contact plates connected via a connecting part, and a first tab extending from both ends of the contact plate.
For the contact plate, a pair of first clamping pieces are curved so that the tips thereof face one side, and for the second contact plate, the tips thereof face the other side. a pair of second clamping pieces each curved so as to bend the connecting portion near both contact plates to connect the contact plates, and the tabs from both ends of each contact plate are bent. This invention provides a double tab receptacle that is characterized in that it allows insertion and attachment.

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

FIG. 1 is a developed view of the double tab receptacle of this invention. This double tab receptacle 1 is made of a thin conductive metal plate such as copper or brass and is connected via a connecting portion 11 at a bending position shown by a broken line. A plurality of tab contact plates 12a, 1
2b and a first tab contact plate 12a extending left and right from both ends of the contact plate, as shown in FIGS. 2 and 3.
A pair of extending pieces 13a, 13 extend on both sides of the side.
b at a right angle to both sides of the other, then bend it from the other side to the one side so as to eliminate a substantially elliptical shape, and curve the tip so that it faces one side of the first tab contact plate 12a to form a pair. The first clamping piece 15a is bent on the second tab contact plate 12b side by bending a pair of extending pieces 14a and 14b extending at both ends thereof at right angles to one side, and then forming a substantially elliptical shape. A pair of second clamping pieces 15b is formed by bending the tip from one side to the other side so that the tip faces the other side of the second tab contact plate 12b, and the end of the side plane The tab insertion guide portions 17 a , 1 are formed by bending the protruding pieces 16 a , 16 b that extend further toward the other side and one side to form a ring.
7b, and the connecting portion 11 is connected to both tab contact plates 12a,
The first and second glide receptacles 18a and 18b are bent and inclined near the receptacle 12b.

4a and l) show the tabs 2a and 2b connected by this tab receptacle 1, both of which are connected by the wire attachment claw 22 that is integrally attached to the contact piece 21, so that the wire 5 can be connected without any electrical or mechanical problems. It is installed like this.

The tab and double tab receptacle of this invention are constructed as described above, and the case where two tabs are connected using this double tab receptacle will be shown in FIGS. 5 and 6.

In FIGS. 5 and 6, 3 and 4 are housings that are both molded with an insulating member, and rectangular tab insertion holes 32 and 42 are bored in the flat plate portions 31 and 41 of the housings 3 and 4, respectively. The inner surface of the flat plate part 31 has a tapered cross section with a slight flat surface remaining at the edge of the tab insertion hole 32, and has a rectangular lock having a tab receptacle insertion hole 33 that communicates with the tab insertion hole 32. A protrusion 34 is provided protrudingly, and a slight flat portion is also left on the inner surface of the flat plate portion 41 at the edge of the tab insertion hole 42 located at a position opposite to the tab insertion hole 32 to communicate with the tab insertion hole 42. Tab receptacle insertion hole 43
A locking protrusion 4 that is sufficiently shorter than the locking protrusion 34 having a
4 is provided in a protruding manner, and furthermore, a vertical wall portion 35.45 is provided around the flat plate portion 31.41, the length of which is longer than the length of the locking projection.

To install the double tab receptacle 1 inside this housing, as shown in FIGS.
7b into the tab receptacle insertion hole 43 so as to face the tab insertion hole 42 of the housing 4, and
When the housing 3 is placed on top of the housing 3, the other side of the double tab receptacle is inserted into the tapered tab receptacle insertion hole 33, and guided by the tapered surface, the other tab insertion guide portion 17
a facing into the tab insertion hole 32, both locking protrusions 34.
It is held vertically between 44 and 44.

If the tabs 2a and 2b are inserted through the tab insertion holes 32.42 while contacting the tab insertion guide portions 17a and 17b, both tab contact plates 12a and 12b and the first and second clamping plates 15 will be connected to each other.
It can be inserted between a and 15b.

In this case, the corners of the clamping pieces 15a, 15b are chamfered and elasticity is imparted by curving the clamping pieces 15a, 15b, so that they have a sufficient pressing force against the tabs 2a, 2b.

Further, the connecting portions 11 of the tabs 2a and 2b are inclined, and this portion serves as a stopper to prevent unnecessary insertion.

As described above, this invention consists of a plurality of tab contact plates connected via a connecting part, and a tab extending from both ends of the contact plate, with the tip facing one surface of the first contact plate. a pair of first clamping pieces curved so as to be opposite to each other, and a pair of second clamping pieces curved such that their tips face the other surface of the second contact plate. , and bending the connecting portion near the circumferential contact plate to connect each of the contact plates,
Since the tabs can be inserted from both ends of each of the contact plates, the tabs can be connected to each other, and since the tabs are symmetrical, it has the advantage of good workability and ease of mass production.
