Description

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

Generally, connectors use a plug-in type electrical connector with an integrated tab and receptacle part, and it is necessary that there be 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.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and the first tab adhesive part and the second tab adhesive part, which face each other in opposite directions, are connected via the first curved part and the second curved part on both sides. A tab connector in which a first tab contact piece is bent at right angles to a second tab contact piece, and a tab connector in which a plurality of such connectors are connected. the tab receptacle is inserted into a predetermined recess in the flexible housing, and the tab plug and/or the first tab contact piece of the tab plug set is connected to the tab plug and/or the first tab contact piece of the tab plug set. The present invention provides a tab connector characterized in that it is inserted and bonded to a second tab bonding portion of a tab receptacle inserted into a housing, and is locked to a locking hook provided in the housing.

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

Fig. 1 is a developed view of a twin-shaped tab receptacle. A pair of arc-shaped chamfers 2a, 2b are formed on both longitudinal edges of a rectangular material 1 by press-punching a thin elastic metal plate such as copper or phosphor bronze.
and guide protrusions 3a and 3b, respectively, and the material 1
Slits 4a to 4c are provided approximately at the center of the slits 4a and 4c, and the chamfered portions 2a and 2b are held outside the curved portions to form the first and second curved portions 5a and 5b. 4c is formed into the first and second parts.
Tab clamping portion formation areas 6a*6b are formed respectively.

As shown in FIG. 2, by curving this tab hooking part forming area 6b and the second curved part forming area 5b, the twin-shaped tab receptacle 9 is formed in the first tab hooking part forming area 6.
a at a predetermined distance (slightly more than the thickness of the tab terminal), and curve the first curved part forming area 5a at the other end edge of the second tab clamping part forming area 6a, and The edges are exposed, and the facing guide protrusions 3a and 3b are each curved outward to form a first
And the second tab clamp? ay7b and first and second curved portions 8a and 8b on both sides, respectively.

The twin-shaped tab connector assembly 10 that is connected to the twin-shaped tab receptacle 9 described above is made by punching a thin elastic metal plate such as copper or phosphor bronze from one edge of a rectangular material 11, as shown in FIG. Cut grooves 12a to 12c and cut grooves 13a to 13c from other lines are provided, and connecting pieces 14a to 14c formed between both grooves are used to connect first tab contact pieces 15a to 1.
5d, the locking pieces 16a to 16d, and the second tab contact piece 17a
17d, the locking pieces 16a to 16a are inserted from the tops of the connecting pieces 14a to 14c, as shown in FIG.
6d and the first tab contact pieces 15a to 15d are bent at right angles to enhance the shape.

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

FIG. 6 shows these twin-shaped tab receptacles 9, twin-shaped tab connector set 10, and twin-shaped tab connectors 20 in unit configuration.
The housing 21 is made of flexible synthetic resin and has an open end, and one side of the end plate 23 of the box body 22 has recesses 24a to 24d into which parts to be connected can be inserted. There are contact piece insertion holes 25a to 25d formed therein so that the contact pieces attached to the component can be inserted therein, and a pair of twin pieces are provided on each side of the contact piece insertion holes 25a to 25d on the other side of the end plate. The clamping pieces 26a, 26b to 29a, 29b which clamp the shaped tab receptacle 9 and the tab plug assembly 10 are connected to the cavity 30.
The clamping pieces 26b to 29b are each provided with a locking hook 32 having a horizontal surface 31 on the inside of which the locking piece 16 locks, and these configurations are as shown in FIG. It is shaped symmetrically on the left and right with the partition plate 33 as the center.

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.

First, as shown in FIG. 7, the twin-shaped tab receptacle 9
One of the guide protrusions 3a is inserted into the contact piece insertion holes 25a to 25d.
A pair of clamping pieces 26a, 26b to 29 are inserted into the
A total of 8 pieces are inserted between a and 29b.

Next, as shown in FIG. 8, a tab connector set 10 in which four tab connectors 17a to 17d are connected to four tab receptacles by connecting pieces 14a to 14c is connected to the first tab connectors 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, four tab connectors 20 are inserted and fixed one by one in the same manner as described above, as shown in FIG. 11.

As a result, as shown in FIG. 12, one of the tab receptacles, one tab connector assembly, and four tab connectors are inserted into the housing 21 without using any fittings, and the hook 32 is inserted into the housing 21 without using any fittings.
As a result, they cannot be removed.

In the figure, reference numerals 34at and 34b are locking frames provided on the outside of the housing 21, in which 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. I'm starting to get it.

As shown in FIGS. 10 to 12, this connector A has a contact piece 29a of the mini fuse 28 on the tab receptacle 9,
29b is connected, tab connection group 10, tab connection group 2
0 is connected to a female connector B inserted into the cavity 30 of the housing 21.

As shown in FIG. 12, the housing 21 is provided with five recesses, five contact insertion holes, and a set of clamping pieces, and one tab receptacle is inserted into the housing 21, and one tab receptacle is inserted into the housing 21, and four tab receptacles are connected. It may be constructed so that a spare mini-fuse 28a can be inserted using a tab plug.

As described above, this invention has a twin-shaped structure in which the first tab adhesive part 7a and the second tab adhesive part 7b facing in opposite directions are connected via the first curved part 8a and the second curved part 8b on both sides. The tab receptacle 9 is shaped with an elastic conductive plate, and the first
A tab connector 20 in which the tab contact piece 15 is bent at right angles to the second tab contact piece 17, and a tab connector set 1 in which a plurality of the connectors are connected.
0 with an elastic conductive plate, the tab receptacle 9 is inserted into a predetermined recess in the flexible housing 21, and the tab connector 20 and/or the first of the tab connector set 10 are The tab contact piece 15 is inserted into the second tab adhesive part 7b of the tab receptacle inserted into the housing, and
Since it is locked with the locking hook 32 provided inside the housing,
Since the tab receptacle and tab can be made individually, processing is easy, and insertion into the housing is easy and strong without the need for fittings.Moreover, the tab receptacle and tab can be made from different materials, so the material size It has the advantage of being easy to handle and can be constructed at low cost.
