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 electrical connector 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 screws, and the end of the electric wire (and the attached tab receptacle) is attached to the tab. The configuration was such that 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, it requires a large number of man-hours to attach the tab or tab receptacle to the insulating substrate, is complicated, and has 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, one edge of this clamping part, and a first tab clamping part in the form of an elastic conductive plate. a second tab clamping part that is connected to the second tab clamping part via a curved part thereof and facing the first tab clamping part at a predetermined interval;
The edge of the second curved part connected to the other edge of the first tab clamping part is brought into contact with the side surface of the edge of the second clamping part, and the longitudinal direction of the clamping part is The spacing between the clamping parts facing each other with the slit formed approximately in the center as a boundary changes according to the thickness of the insertion tab terminal, so that tab terminals of different thicknesses can be inserted between the clamping parts. A twin tab receptacle is provided.

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. This tab receptacle 1 is made by punching and bending a thin elastic metal plate such as copper or phosphor bronze, and its structure is a flat plate formed on 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 which is opposed to each other with a gap (slightly smaller than the width of the tab) and the first curved part 13 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 (7) are cut and raised on the opposing surface of the clamping portion at approximately the center of 5 so as to lock onto a pair of mounting protrusions made of an insulator.
and 17a, 17b, and the edges of the tab clamping parts 12.14 of both clamping parts 12.14 are respectively formed with protruding insertion guide parts 18, 19 for facilitating the insertion of the tab terminal, By varying the opposing distances between the clamping parts 12, 14 and the slit 1A formed approximately at the center in the length direction of the clamping parts 12a and 14, the thickness between the clamping parts can be increased. It is configured such that different tab terminals 2 and 2a can be inserted therein.

2a and 2 show the tab terminals 2 and 2a inserted between the tab clamping portions 12.14 and 12a of the tab receptacle 1, and 21. in each of the above four figures.
21 a 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-described 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 the end surface of each locking protrusion has curved parts 35a, 35b, 36a, 36 that follow the outer peripheral curved surface of the curved part 13.15.
b 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 then the locking protrusions 33a, 33b and curved portions 35 a, 35 b, 36 a of arcuate portions 35 and 36 of 34 a and 34 b
, 36b, and expands outward again on the upper surface, and at this time, the insertion guide portions 18, 19 are located in the tab insertion hole 32, making it easier to insert the tab terminal 21a, and the receptacle 1 Even if it is attempted to move in the opposite direction to the mounting direction or in the lateral direction, the locking claws and the curved portions 35a, 35b, 36a, 36b of the protrusions work effectively, and the board 3 is completely mounted.

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 212 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 distance between the clamping parts is configured to change depending on the thickness of the insertion tab terminal, with the slit 1A formed at approximately the center in the length direction of the clamping parts as a boundary, thick tabs are used. The insertion piece 21a of the terminal 2a and the insertion piece 21 of the normal thickness tab terminal 2 can be inserted from both the top and bottom of the tab receptacle 1, and as shown in FIG. By providing this, even if tab terminals of different thicknesses are inserted, they will be completely sandwiched.

In addition, although the above-mentioned receptacle was described as having a slit 1A as shown in the developed view shown in Fig. 6, the slit may be provided on either the left or right side, and further, as in the modified example shown in Fig. 7. A through hole is provided in place of the locking claws 16 and 17,
A locking protrusion 36a is provided in this through hole.

36b 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. While making contact with the side surface of the end edge of the second clamping part, the opposing interval of each clamping part is adjusted according to the thickness of the insertion tab terminal, with the slit formed approximately at the center in the length direction of the clamping part as a boundary. Since the configuration is such that tab terminals with different thicknesses can be inserted between these clamping parts, at least two types of tab terminals with different thicknesses can be inserted into one type of tab receptacle with good compatibility. It can be inserted and used with easy contact,
In addition, the insertion positions of tab terminals of different thickness can be replaced with each other, and there is no directionality and the device is easy to use.
