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 there must be a difference in plate thickness between the tab side and the septacle side depending on the application, so it is unavoidable. In order to obtain strength on the tab side, it is bent, but manufacturing is troublesome and takes a lot of man-hours.
Even when it is housed and fixed in the housing, there are drawbacks such as poor handling.

This consideration aims to eliminate the above-mentioned drawbacks, and its feature is that the central protrusion of the roughly T-shaped elastic conductive plate is folded back to form the first tab clamping part. , a first button and a second curved piece are provided facing each other in connection with the side edges of the clamping part, and a first button and a second curved piece are provided facing each other and are connected to the side edges of the clamping part, and a first button and a second curved part are formed of the end edges of both curved parts and the back surface of the first tab clamping part. A two-way type tab receptacle having two tab clamping parts, a first tab at one end bent at right angles approximately in the center, a locking piece at the other end, and a second tab at the bottom. The formed twin-shaped tab connector (a tab connector assembly in which a plurality of tab connectors are connected by connecting pieces), and the end plate of the box body with one end open has a hook on one side corresponding to the insertion hole. A connector comprising a housing in which a pair of formed clamping pieces are made to protrude into a cavity, and a tab receptacle, a tab connector, and a tab connector set are clamped and locked between the pair of clamping pieces. It provides:

An embodiment of this proposal 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 plate such as copper or phosphor bronze into a substantially T shape, and a guide protrusion 2 is attached to the upper edge of this material.
At the same time, the central projecting piece 3 extending downward is formed into a third
As shown in the figure, the protruding piece is folded back between the notches 4.4 provided at both ends to form a first tab clamping part 5, and the first and second curved parts are connected to the side edges of the clamping part. The first and second curved pieces 6a, 6b are provided facing each other by bending the pieces 6a, 6b so that the folded portion 3a formed by folding back the central projecting piece 3 is positioned inside the curved portion. A second tab clamping part 8 is constituted by the end edges 7a, 7b of both curved pieces and the back surface of the first tab clamping part 5, and furthermore, the opposing guide protrusions 2.2a are arranged outwardly. A two-way insertion type tab receptacle is formed by curving the central projecting piece 3 and forming first and second tab clamping parts 5.8 from above and below and first and second curved pieces 6a and 6b on both sides, respectively. Get 9.

The twin-shaped tab plug set 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 12C from the other end and cut grooves 13a to 13c from the other end are provided, and connecting pieces 142 to 14c formed between both grooves connect the first tab contact piece 15a.
~15d, locking pieces 16a and 16d, and second tab contact piece 1
7a to 17d, as shown in FIG.
16d and the first tab contact pieces 15a to 15d are bent at right angles.

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.

FIG. 6 shows these bidirectional insertion type tab receptacles 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 each of the clamping pieces 26b to 29°b has a horizontal surface 31 on the inside of which the locking piece 16 locks. A hook 32 is formed, and as shown in FIG. 11, these structures are formed symmetrically laterally around a partition plate 33.

The configuration of each part constituting the connector of this invention has been shown above, and the assembly sequence for constructing the on-vehicle fuse connector A with each of these parts will be explained below.

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. 8, the tab connector assembly 10 in which the four tab contact pieces 17a to 17d are connected to the four tab receptacles by the connection pieces 142 to 14c is connected to the first tab contact pieces 15a to 1.
5d is inserted into the tab receptacle 9, and the locking pieces 16a to 1
6d 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,
Here, as shown in FIG. 11, four tab connectors 20 are inserted and fixed one by one in the same manner as described above.

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 on the lid 35 and the locking claws provided on the outside of the housing 37 constituting the female connector 36. can be locked.

In this connector A, as shown in FIGS.
A female connector B inserted into the cavity 30 of the housing 21 is connected to the tab connector set 10 and the tab connector 20.

As shown in Fig. 12, 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, four connected tab plug sets, and four tab receptacles. It may be constructed so that a spare mini-fuse 28 can be inserted using a tab plug.

As described above, this invention forms a first tab clamping part by folding back the central projecting piece of a roughly T-shaped elastic conductive plate, and connects the side edges of this clamping part to the first and second tabs. A two-way insertion type tab receptacle having curved pieces facing each other and having a second tab clamping part constituted by the end edges of both front curved pieces and the back surface of the first tab clamping part; A twin-shaped tab connector with a first tab on one end bent at right angles in the center, a locking piece on the other end and a second tab on the bottom, and a twin tab connector with a connecting piece. A plurality of tab plug sets arranged in a row and a plurality of insertion holes for inserting the contact pieces of the connected parts are made in the end plate of the box body with one end open, and the contact pieces of the connected parts are inserted into the end plate. a plurality of pairs of insertion holes are formed in the end plate, and the end plate includes a housing in which a pair of clamping pieces each having a hook formed on one side corresponding to the insertion hole protrudes into the cavity; Since the tab receptacle, tab plug bag, and tab plug assembly are clamped and locked between the two halves, the tab receptacle and tab can be made individually, making it easy to insert into the caroe and housing C. Since the 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.
