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 type electrical connection terminal consisting of a tab and a tab receptacle is attached to an insulating board with the tab side using fixing means such as caulking or screwing, and the tab receptacle attached to the end of the wire is attached to the 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 contact plate extending from both ends of the contact plate. A pair of first clamping pieces are curved so that their tips are opposed to one surface of the plate, and a pair of first clamping pieces are curved so that their tips are opposed to the other surface of the second contact plate. The present invention provides a double tab receptacle characterized in that the double tab receptacle is provided with a pair of curved second clamping pieces, and the tabs can be inserted from both ends of each of the contact plates.

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

Figure 1 is an exploded view of the double tab receptacle of this invention, and this double tab receptacle 1 is made of copper.

A plurality of tab contact plates 12 are connected via connecting portions 11 at the bending positions shown by broken lines from a thin conductive metal plate such as brass.
a, 12b, and a first tab contact plate 12 extending left and right from both ends of the contact plate, as shown in FIGS. 2 and 3.
The a side has a pair of extending pieces 13a extending on both sides thereof,
13b at a right angle to the other surface, then bend it from the other surface to the one surface so as to form a substantially ellipse, and curve the tip so that it faces one surface of the first tab contact plate 12a, forming a pair of tab contact plates 12a. 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. The second tab contact plate 12b is bent from one side to the other side to form a pair of second clamping pieces 15b, with the tip thereof facing the other side of the second tab contact plate 12b, and the end of the side plane The tab insertion guide portions 17a, 17 are formed by bending the projecting pieces 16a, 16b extending from the tab insertion guide portions 16a, 16b toward the other side and one side to form a ring.
b forming first and second glue receptacles 18a,
18b.

Fig. 4a and l) show the tabs 2a and 2b connected by this tab receptacle 1, and the electric wire 5 is connected by the electric wire attachment claw 2 which is integrally attached to the contact piece 21 without any mechanical inconvenience. 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, housings 3 and 4 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. On the inner surface of the flat plate part 31, a rectangular locking protrusion 34 has a tapered cross section, leaving a slight flat part on the edge of the tab insertion hole 32, and has a tab receptacle insertion hole 33 that communicates with the tab insertion hole 32. Similarly, on the inner surface of the flat plate part 41, a tab receptacle is inserted, which communicates with the tab insertion hole 42 by leaving a slight flat part on the edge of the tab insertion hole 42, which is located opposite to the tab insertion hole 32. A locking projection 44 that is sufficiently shorter than the locking projection 34 having a hole 43 is provided protrudingly, and further has vertical wall portions 35, 45 longer than the length of the locking projection around the flat plate portion 31.41. It is.

To install the double tab receptacle 1 inside this housing, as shown in FIGS.
7b is inserted into the tab receptacle insertion hole 43 so that it faces the tab insertion hole 42 of the housing 4, and when the housing 3 is superimposed on the housing 4, a double tab is inserted into the tapered tab receptacle insertion hole 33. When the other tab receptacle is guided by the crowd taper and the other tab insertion guide part 17a faces into the tab surface insertion hole 32, both locking protrusions 34.44
held vertically between.

If the tabs 2 a , 2 b are inserted through the tab insertion holes 32 . 42 while contacting the tab insertion guide portions 17 a , 17 b , both tab contact plates 12 a , 12 b and the first and second clamping pieces 15 a , 15 are inserted. It can be inserted between B.

In this case, the corners of the clamping pieces 15a, 15b are chamfered and curved to impart elasticity, so that they have a sufficient pressing force against the tabs 2a, 2b.

As described above, this invention includes a plurality of tab contact plates connected via a connecting part, and a tip extending from both ends of the contact part and facing one surface of the first contact plate. a pair of first clamping pieces that are curved in a similar manner; and a pair of second clamping pieces that are curved so that their tips face the other surface of the second contact plate; 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, the contact plate has advantages such as good workability and easy mass production.
