Description

[Detailed description of the invention] This invention relates to a twin tab receptacle, and more specifically, to an improvement of the tab clamping structure of a plug-in twin tab receptacle that allows tab terminals of different thicknesses to be inserted. be.

In general, a plug-in type electrical connector consisting of a tab and a tab receptacle is attached to an insulating board on the tab side using fixing means such as caulking or screws, and the tab receptacle attached to the end of the wire is inserted into this tab. Alternatively, a tab receptacle was housed and fixed in the housing, and a tab to which an electric wire was attached was inserted into the tab receptacle.

However, tab terminals require a large number of man-hours to attach the tab receptacle to the insulating substrate, are complicated, and have drawbacks such as the inability to insert tab terminals of different thicknesses.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a first tab clamping part in the form of an elastic conductive plate, and one edge of this clamping part and the first tab clamping part. a second tab clamping part that is connected to the first tab clamping part through a curved part and facing the first tab clamping part at a predetermined interval; The edge of the second curved part connected to the edge of the second clamping part is brought into contact with the edge side surface of the second clamping part, and each clamping part The purpose of the present invention is to provide a twin tab receptacle configured so that tab terminals of different thicknesses can be inserted between the respective clamping portions by making the opposed spacings different.

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

Figure 1 is a perspective view of a twin-shaped tab receptacle 1. This tab receptacle 1 is made by punching and bending a thin sheet of elastic metal such as copper or phosphor bronze, and its structure is a flat plate shaped into an elastic conductive plate. The first tab clamping part 12 is connected to the first tab clamping part 12 via one edge of the tab clamping part and the first curved part 13, and is connected to the first tab clamping part 12 at a predetermined interval (the thickness of the tab terminal). A flat second tab clamping part 14 facing each other with a gap (slightly more than the middle) in between, and a first curved part 13 which is brought into contact with the outer surface of the other edge side of the first tab clamping part 12. The second clamping part 14 is curved so as to impart elasticity to both ends of the second clamping part 14.
along with the curved portion 15 of the first and second curved portions 13,1
As will be described later, a pair of locking claws 16a, 16b and 17a are cut and raised on the opposing surface of the clamping portion at approximately the center of 5 so as to lock into a pair of mounting protrusions formed on an insulator, respectively. 17b and the tab clamping parts 12.14 of both clamping parts 12.14, insertion guide parts 18 and 19 are respectively provided in a protruding form to facilitate insertion of the terminal, and the clamping parts 12. .14 and the clamping part 12a, 1
By making the facing distances of the clamping parts different with respect to the bisecting point 1A in the length direction of 4, the tab terminals 2 and 2a having different thicknesses can be inserted between the clamping parts. This is what I did.

Figures 2a and 2 show the tab terminals 2 and 2a inserted between the tab clamping portions 12.14 and 12a, 14 of the tab receptacle 1;
13 is a plate-shaped insertion terminal piece, and 22 is a crimp connection portion for the electric wire 5.

FIG. 3 shows an insulating board 3 to which the tab receptacle 1 having the above-mentioned structure can be attached, and the flat plate part 31 of the insulating board 3 has a tab insertion hole 32 large enough to allow the thick insertion piece 21a to be inserted freely. is opened, and on the bottom side of the board, there are oval-shaped locking protrusions 33a and 33b extending downward from both sides of this hole.
and 34a, 34b protrude to face each other, and each locking protrusion has curved portions 35a, 35b, 36a, 3 on the end surface that follow the outer peripheral curved surface of the curved portion 13.15.
6b is formed.

In the tab receptacle 1 of this invention, the curved portions 13 and 15 are locking protrusions 33a with respect to the base plate 3, as shown in FIG.

33b, 34a, and 34b and is pushed toward the side of the flat plate part 31, the locking claws 16a, 16b and 17a, 17b temporarily loosen inward, and the locking protrusions 33a, 33b and 34 a, 34 b (7)
Arc-shaped portion 35.36 (7) Curved portion 35 a, 35
b, 36a, 36b and expands outward again on the upper surface, and at this time, the insertion guide portion 18.19 is positioned in the tab insertion hole 32, so that the tab terminal 21a
The curved portions 35 a, 35 b, 36 a, and protrusions of the locking claws and protrusions make it easier to insert the receptacle 1 even if the receptacle 1 is moved in the opposite direction to the mounting direction or in the lateral direction.
36b works effectively and is completely attached to the substrate 3.

To connect the electric wire 5, as shown in FIG.
By inserting the tab terminal insertion piece 21 a from above between the tab clamping parts 12 a and 14 of the tab receptacle through the tab insertion hole 32 from the upper surface side, and inserting the insertion piece 2 from below, these insertion pieces 21 and 218 upper and lower electric wires 5
, 5 are electrically and mechanically connected.

That is, as shown in FIG. 5, tab terminals can be connected to the top and bottom of the tab receptacle 1 by inserting the tab terminal insertion pieces 21 upward from below the tab receptacle 1 in the same manner as described above.

As mentioned above, since the opposing distances between the clamping parts are different from each other at the bisecting point 1A in the length direction of the clamping parts, the insertion piece 21a of the thick tab terminal 2a and the tab terminal 2 of normal thickness are different. The insertion pieces 21 can be inserted from both the top and bottom of the tab receptacle 1, and as shown in FIG. Each is completely sandwiched.

In addition, as mentioned above, the septacle was described with a bisecting point 1A as shown in the developed view shown in Figure 6, but the bisecting point 1A is
may be provided on either the left or right side.Furthermore, as in the modification shown in FIG. It may be configured to be locked.

As described above, this invention includes a first tab clamping part formed on an elastic conductive plate, one edge of this clamping part connected via a first curved part, and a first tab clamping part connected to the first tab clamping part through a first curved part. and a second tab clamping part facing the first tab clamping part at a predetermined interval, and the end edge of the second curved part connected to the other edge of the first tab clamping part is connected to the second tab clamping part. By abutting against the side surface of the end edge of the second clamping part, and by varying the opposing intervals of each clamping part with the bisecting point in the length direction of the clamping part as a boundary, the gap between each clamping part is Since the structure is such that tab terminals of different thicknesses can be inserted into one type of tab receptacle, at least two types of tab terminals of different thickness can be inserted and used interchangeably and with good contact. have
