Description

[Detailed description of the invention] This invention relates to a twin tab receptacle, and more specifically, to an improvement in the mounting structure of a plug-in twin tab receptacle to an insulating substrate. 3 Generally, it consists of a tab and a tab receptacle. For plug-in type electrical connectors, attach the tab side to the insulating board using fixing means such as caulking or screws, and insert the tab receptacle attached to the end of the wire into this tab, or insert the tab receptacle into the housing. It was designed to be housed and fixed, and a tab with an electric wire attached was inserted into it.

However, the number of man-hours required to attach the tab or tab receptacle to the insulating substrate is large and complicated.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a first tab clamping part formed on an elastic conductive plate, one edge of this tab clamping part, and a a second tab clamping part connected via a curved part and facing the first tab clamping part at a predetermined distance; and a second tab clamping part connected to the other edge of the first tab clamping part. The edge of the second curved portion is faced to the edge of the second clamping portion, and both curved portions are cut so as to be locked to a pair of locking protrusions formed on the insulating substrate. Forming a pair of locking claws,
A twin tab receptacle that can be easily attached to an insulating substrate 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 tab receptacle with electric wires attached. This tab receptacle 1 is made by punching and bending a thin sheet of elastic metal such as copper or phosphor bronze. A flat first tab clamping part 12 having an electric wire connecting part 11 and a first tab clamping part 12 connected to one edge of the tab clamping part via a first curved part 13. and a flat second tab clamping part 14 which faces each other at a predetermined interval (slightly smaller than the thickness of the tab terminal), and a second tab clamping part 14 facing the other edge side of the first tab clamping part 12. The first and second curved portions 13.15 are curved along with the second curved portion 15 which is curved so as to impart elasticity to both ends of the second clamping portion 14 together with the first curved portion 13. 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 so as to lock onto a pair of mounting protrusions formed on an insulator, as will be described later.

17b, tabs of both clamping parts 12.14, clamping parts 12
Insertion guide portions 18 and 19 are formed protruding from the edges of each of the ends of the tab terminals 18 and 14 to facilitate insertion of the tab terminals.

Figures 2a and 2 show the tab terminal 2 inserted between the clamping parts 12 and 14 of this tab receptacle, and in each of the above figures, 21 is a plate-shaped insertion terminal piece, and 22 is a plate-shaped insertion terminal piece. This is a crimp-connected portion of 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.A tab insertion hole 32 of a size that allows the insertion piece 21 to be freely inserted is bored in the flat plate part 31 of the insulating board 3. , on the lower surface side of the board, there are abbreviated locking protrusions 33a, 33b, and 3 below from both sides of this hole.
4a and 34b protrude so as to face each other, and curved portions 35a, 35b, and 36a36b are formed on the end surface of each locking protrusion so as to follow the outer peripheral curved surface of the curved portion 13.15.

The tab receptacle 1 of this invention has a curved portion 13.15 with a locking protrusion 33a, as shown in FIG.
33b and 34a.

34b and is pushed toward the side of the flat plate part 31, the locking claws 16a, 16b and 17a,
17b temporarily loosens inward, and then the locking protrusion 33a,
33b and 34a, the curved portion 35a of the arcuate portion 35.36 of 34b.

35b, 36a, and 36b, and expand 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 21, and the receptacle 1 Even if an attempt is made to move it 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 pieces 21.21 from both the upper and lower sides between the tab clamping parts 12.14 of the tab receptacle through the tab insertion holes 32 from the upper surface side, these insertion pieces 2
1.2L Therefore, the upper and lower electric wires 5.5 are electrically and mechanically connected.

That is, as shown in FIG. 4, 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.

Furthermore, the second curved portion 1 of the receptacle 1 according to this invention
As shown in FIG.
The end surface of the curved portion 15 may be in contact with the tab terminal, and the locking claw 16 may be placed on the flat surface of the first and second curved portions 13.15. .17 is cut and bent, and the locking protrusion 3 is attached as shown in FIG.
3.34 may be locked by hook-shaped portions 37.38.

In addition, in FIGS. 5 and 6, parts given the same reference numerals as in FIGS. 1 to 4 above indicate the same or equivalent parts.

As described above, this invention connects a first tab clamping part formed on an elastic conductive plate to one edge of this tab clamping part via a first curved part, and connects the first tab clamping part to the first tab clamping part. a second tab clamping part facing the section at a predetermined distance; and an end edge of a second curved part connected to the other edge of the first tab clamping part. A pair of locking pawls are formed on each of the curved portions of the insulating substrate, facing the edge of the section, and are cut and raised to lock onto a pair of locking protrusions formed on the insulating substrate. Installation to the locking protrusion formed on the board does not require fixing means such as screws, and it can be inserted automatically, and there is no accident of falling off from the insulating board when inserting the tab terminal after installation. It has the effect of
