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 first tab clamping part formed on an elastic conductive plate. a second tab clamping part that is connected to the first tab clamping part through a curved part thereof and facing the first tab clamping part at a predetermined distance; and the other edge of the first tab clamping part. The edges of the connected second curved portions face the edges of the second clamping portion, and both curved portions are transparent so as to be locked to a pair of locking protrusions formed on the insulating substrate. A twin tab receptacle is provided in which each pair of holes is formed to facilitate attachment to an insulating substrate.

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 a connecting part 11, one edge of this tab clamping part and the first curved part 1
3, and a flat second tab clamping part 14 facing the first tab clamping part 12 at a predetermined distance (slightly smaller than the thickness of the tab terminal); The first curved portion 13 faces the 29 law surface on the other end side of the tab clamping portion 12 of No. 1.
Together with the second curved part 15 which is curved so as to impart elasticity to both ends of the second clamping part 14, the clamping parts face each other approximately at the center of the first and second curved parts 13.15. As will be described later on the surface side, through holes 16a, 16b and 17a, 17b are respectively provided in the tab clamping parts 12 of both clamping parts so as to be engaged with a pair of mounting protrusions formed on the insulator. ．． Insertion guide portions 18 and 19 are formed protruding from the edges of each of the terminals 14 to facilitate insertion of the tab terminal.

Tab clamping portion 12 of tab receptacle 1 shown in FIGS. 2a and 2b. In each of the above figures, 21 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.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 bottom side of the board, there are locking protrusions 33a, 33b, and 34a in the shape of an abbreviation below both sides of this hole.
, 34b protrude so as to face each other, and the end face of each locking protrusion has a curved portion 13. 15 round holes 16a, 16
b, step portions 35a, 3 that enter into 17a, 17b
5b, 36a, and 36b are formed.

The tab receptacle 1 of this invention has a curved portion 13.15 with a locking protrusion 33a, as shown in FIG.
33b, 34a, and 34b when pushed in the side direction of the flat plate part 31, the locking protrusion curves against the elasticity as shown by the chain line, and then the through holes 16a, 16b, and 17a are formed. Steps 35a, 35b of the trapezoidal portions 35.36 of the locking protrusions 33a, 33b and 34a, 34b in 17b.

36a and 36b are inserted and locked.

At this time, since the insertion guide portions 18 and 19 are located in the tab insertion hole 32, the tab terminal 21 can be easily inserted, and even if the receptacle 1 is moved in the opposite direction to the installation direction or in the lateral direction, the through hole and Steps 35a and 35b of the protrusion
36a and 36b work effectively and are completely attached to the substrate 3.

To connect the electric wire 5, as shown in FIG.
The tab clamping portion 12. of the tab receptacle is passed through the tab insertion hole 32 from the top side. By inserting the insertion pieces 21, 21 of the tab terminals from both sides of the terminal 14, the insertion pieces 21, 21 and 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 through hole 16. 17 is a locking protrusion 33.3 as shown in FIG.
The trapezoidal portions 37 and 38 of No. 4 may be used for locking.

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

As described above, this invention includes a first tab clamping part formed on an elastic conductive plate, one edge of this tab clamping part being connected via a first curved part, and the first tab clamping part being connected to one edge of the tab clamping part through a first curved part. The second tab clamping part faces the attachment part at a predetermined distance, and the edge of the second curved part connected to the other edge of the first tab clamping part is connected to the second clamping part. A pair of through holes were formed in each curved portion of the insulating substrate so as to face the edge of the mounting portion and engage with a pair of locking protrusions formed on the insulating substrate. Installation to the formed locking protrusion does not require fixing means such as screws, and it can be inserted automatically.
Furthermore, there is an effect that an accident of falling off from the insulating substrate does not occur even when the tab terminal is inserted after installation.
