Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector, and more particularly to a connector configured with twin tabs and a bidirectional tab receptacle.

In general, connectors use a plug-in type electrical connector with an integrated tab and receptacle part, and it is necessary to have a difference in plate thickness between the tab side and the receptacle side depending on the purpose. Although it is bent to obtain strength, manufacturing is troublesome and requires a lot of man-hours, and furthermore, there are disadvantages such as poor handling when housing and fixing it in a housing.

This invention is aimed at eliminating the above-mentioned drawbacks, and its features are that the central projecting piece of the approximately T-shaped elastic conductive plate is folded back to form the first tab clamping part; first and second curved pieces are provided facing each other in connection with the side edges of the clamping part of the tab, and a second A two-way insertion type tab receptacle having a tab clamping part, a first tab bent at a right angle approximately at the center, a first tab provided at one end, a locking piece provided at the other end, and bent toward one edge of the locking piece. The insertion hole is formed in the end plate of the box body with one end open. To provide a connector comprising a housing in which a clamping piece with a hook formed on one side projects into the cavity, and a tab receptacle and a tab plug are clamped and locked between the clamping pieces. It is.

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

Fig. 1 is a developed view of a two-way insertion type tab receptacle, in which a material 1 is formed by press punching a thin elastic metal sheet such as copper or phosphor bronze into a substantially T shape, and a guide protrusion is attached to the upper edge of the material. The central projecting piece 3 which is rolled downward while forming the second
As shown in the figure, the projecting piece is folded back between the notches 4, 4 provided at both ends to form a first tab clamping part 5, and first and second curved pieces are connected to the side edges of this clamping part. The first and second curved pieces 6a, 6b are provided facing each other by curving 6a, 6b so that the folded portion 3a formed by folding back the central protruding piece 3 described above is located inside the curved portion, A second tab clamping part 8 is formed by the edges 7a, 7b of both curved pieces and the back surface of the first tab clamping part 5, and the opposing guide protrusions 2, 2a are each curved outward. A two-way insertion type tab receptacle 9 is formed by forming first and second tab clamping parts 5, 8 from above and below and first and second curved pieces 6a, 6b on both sides of the central projecting piece 3, respectively. obtain.

The twin-shaped tab connector assembly 10 that is connected to the two-way insertion type tab receptacle 9 is made by press-punching an elastic metal plate such as copper or phosphor bronze to form one edge of a rectangular material 11, as shown in FIG. Cut grooves 12a to 12d from the line and grooves 13a to 13c from the other line are provided, and connecting pieces 14a to 14c formed between both grooves form the first tab contact piece 15a.
Locking pieces 16a to 16d rolled to the right by ~15d;
After forming the second tab contact pieces 1γa to 17d, as shown in FIG.
7a to 17d are bent at right angles, and the above-mentioned locking piece 16 is
It is formed by bending the second tab contact pieces 17a to 17d at right angles to a to 16d.

FIG. 5 shows a tab connector 20 having a twin unit configuration, which is constructed by one of the twin tab connector sets 10 described above, and the configuration of each part is the same as that of the tab connector assembly.

FIGS. 6 and 7 show a modification of the above-mentioned twin-shaped tab connector assembly, in which 5-shaped notch grooves 18a to 18d are used in the locking piece instead of the L-shaped notch grooves shown in FIG. Notches 19a to 19d are formed in 16a to 16d.

FIG. 8 shows these two-way insertion type tab receptacle 9,
A housing 21 made of synthetic resin is used to mount a twin-shaped tab connector set 10 and a unit-configured twin-shaped tab connector 20. A part of the connected parts is mounted on one side of an end plate 23 of a box body 22 that is open at one end. Recesses 24a to 24d are formed into which the contact pieces attached to the component can be inserted, and contact piece insertion holes 25a to 25d are formed in these recesses so that the contact piece attached to the component can be inserted. A pair of two-way insertion type tab receptacles 9 and a tab contact set 10 are provided on both sides of the contact piece insertion holes 25a to 25d.
Clamping pieces 26a, 26b to 29a, 29b protrude into the cavity 30, and locking pieces 16 have locking horizontal surfaces 31 inside the ends of the clamping pieces 26b to 29b. 32, and these structures are formed symmetrically in the left and right directions with the partition plate 33 as the center, as shown in FIG.

The above has shown the configuration of each part that makes up the connector of this invention.
The assembly order that constitutes the will be explained.

1. First, as shown in FIG.
A pair of clamping pieces 26a, 2 so as to protrude into the insides of a to 25d.
A total of four pieces are inserted between 6b to 29a and 29b.

Next, as shown in FIG. 10, the four tab contact pieces 17a to 17d are connected to the four tab receptacles by connecting pieces 14a to 14c.
The tab connector set 10 which is connected with the first tab connector pieces 15a to
15d is inserted into the tab receptacle 9, and the locking pieces 16a~
16d is attached to the horizontal surface 31 of the hook 32 using the elasticity of the clamping piece, as shown in FIG.

Apart from this, four tab receptacles 9 are similarly inserted on the other side that is configured symmetrically around the partition plate 33,
In this case, four tab connectors 20 are inserted and fixed one by one in the same manner as described above, as shown in FIG. 13.

As a result, the housing 21 has 1 as shown in FIG.
0 tab receptacles, 1 tab plug set, and 4 tab plugs are inserted without using any fittings, and the hooks 32 prevent them from being removed.

In the figure, 34a and 34b are locking frames provided on the outside of the housing 21, and the locking claws of the lid 35 and the locking claws provided on the outside of the housing 37 constituting the female connector 36 are locked. It is now possible to do so.

As shown in FIGS. 12 to 14, this connector A has contact pieces 28A and 2 of the mini fuse 28 in the tab receptacle 9.
8B is connected, and the tab connector set 10° tab connector 20 has a female connector B inserted into the cavity 30 of the housing 21.
is connected.

As shown in Fig. 14, the housing 21 is provided with five recesses, five contact insertion holes, and a pair of clamping pieces, into which 100 tab receptacles are inserted, and four connected tab connector assemblies and four tab connectors. It may also be configured such that a spare mini-fuse 28 can be inserted with the stopper.

As described above, this invention involves folding back the center projecting piece of a roughly T-shaped elastic conductive plate to form a first tab clamping part, and connecting the side edges of the clamping part with the first and second tabs. a two-way insertion type tab receptacle having two curved pieces facing each other and having a second tab clamping part formed of the edges of both front curved pieces and the back surface of the first tab clamping part; A twin-shaped tab connector in which a tenth rib is provided at one end bent at a right angle approximately in the center, a locking piece is provided at the other end, and a second tab is formed by bending one edge of the locking piece. and (a tab connector assembly in which a plurality of these tab connectors are connected with connecting pieces), a plurality of sets of insertion holes for inserting the contact pieces of the connected parts are made in the end plate of the box whose one end is open, and the above-mentioned A plurality of sets of insertion holes are formed in the end plate for inserting the contact pieces of the connected parts, and the end plate has a housing in which a clamping piece with a hook formed on one side corresponding to the insertion hole protrudes into the cavity. Since the tab receptacle and tab plug are clamped and locked between the pair of clamping pieces, processing to individually manufacture the tab receptacle and tab and insertion into the housing are easy. It is easy to use, and since the tab receptacle and the tab can be made of different materials, the dimensions of the materials can be easily determined, and the construction can be made at low cost.
