Description

Description: TECHNICAL FIELD The present invention relates to a joint connector used to connect various and complicated electric circuits such as a harness circuit of an automobile.

[Related Art] For example, as a joint connector used in a harness circuit of an automobile, a connector using a connection end formed by punching a conductive metal plate is already known. This type of joint connector has excellent advantages such as being able to branch and connect an electric wire from a small number of buses to a large number of slave wires, and to achieve a connection between a large number of connection terminals at once with a single touch. I have.

[Problems to be Solved by the Invention] However, in the conventional connection end, if this connection end is fixed to the housing by molding, there is almost no freedom of circuit change. Also, it is known that a required number of connection ends are connected separately from the rear of the housing and inserted and used, but it takes time to assemble.
There is a disadvantage that the posture of the connection end is difficult to stabilize.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and to provide a joint connector that uses a terminal connecting body in which a predetermined number of connecting ends are connected by a synthetic resin material and is easy to assemble and change a circuit.

Means for Solving the Problems In order to achieve the above object, in a joint connector according to the present invention, a base of a metal body in which a conductive metal plate is punched out and a plurality of connection ends are connected by a bridging portion. A terminal connection body molded with a synthetic resin material and provided with a window in the mold portion so that the bridge portion is exposed is attached to a rear portion of a housing made of a synthetic resin material, and a terminal receiving hole provided in the housing is provided. A joint connector that individually protrudes the connection end from the inside thereof,
The terminal connector is characterized in that the predetermined bridging portion is cut and used in the window portion.

[Operation] The joint connector having the above-described configuration can be easily assembled by fixing the terminal connector to the housing in which the bridge between the connection ends is arbitrarily cut.

[Example] The present invention will be described in detail based on an illustrated example.

FIG. 1 is a sectional view, and FIG. 2 is a perspective view. In the front part of a housing 1 made of a synthetic resin material, for example, a circular section for inserting a female connection terminal 2 as shown in FIG. A plurality of terminal receiving holes 3 are provided. A connector fixing portion 5 for attaching the terminal connector 4 is provided at a rear portion of the housing 1, and a tongue-shaped connection end 4 a extending from the terminal connector 4 and made of conductive metal is provided in each terminal housing. The connection end insertion hole 6 provided at the back of the hole 3 protrudes into the terminal receiving hole 3 so that it can be fitted into the connection portion of the female connection terminal 2.

The connection ends 4a are connected to each other by a bridging portion 4b of the same material as shown in FIGS. 4 and 5, and the bridging portion 4b is further removed by, for example, eight molding resin portions 4c made of a synthetic resin material. The base is molded, and the terminal connector 4 is formed with a wall 4d integrally with the frame 4c at the rear. And the bridging part 4b provided in the synthetic resin material is exposed from the window provided in the mold part. In FIG. 4, the connection end 4a is connected to the bridge.
4b, the connection ends 4a are molded and cut by eight by the formwork portion 4c and the wall portion 4d so that the terminal connector 4 is manufactured as shown in FIG. Has become.

In forming a circuit, the bridge portion 4b is cut with a gap provided by using a window according to the required number of connection ends 4a. For example, as shown in FIG. 5, when the bridging portion 4b is cut at two locations A and B, a set of three, two, and three connection ends 4a is obtained, and the female connection terminal 2 is Are short-circuited by three, two, and three at a time in accordance with the fitting of the connection end to the connection end 4a.

As shown in FIG. 6, the eight terminal ends 4a are connected to each other by at least a form part 4c and a wall part 4d. As shown in FIG. 1, the connector holding member 7 is attached to the bottom box-shaped waterproof connector holding member 7 in two stages, and then the connector holder 7 is attached to the housing 1.
The connection end 4a protrudes inward from a gap provided in the terminal receiving hole 3 by being attached to the connecting body fixing portion 5 of FIG. The connector holding portion 7 is provided with a groove 7a for fixing the wall 4d of the terminal connector 4, and the terminal connector 4 is stabilized by fitting the wall 4d into the groove 7a.

A lead wire 2a is connected to the rear end of the female connection terminal 2 by crimping, and a sealing member 2b for waterproof is provided around the rear end.
When the female connection terminal 2 is inserted into the terminal receiving hole 3, the sealing member 2 b is brought into close contact with the inner wall of the terminal receiving hole 3. After the female connection terminal 2 is inserted and connected to the connection end 4a of the terminal connector 4, the housing 1 is fixed to the housing 1 by a rear holder 8 made of synthetic resin.
Are fitted, and the rear end of the female connection terminal 2 is locked by a locking portion 8a so that the female connection terminal 2 does not fall out of the housing 1.

As described above, the electrical connection between the female connection terminals 2 is made via the connection end 4a. At this time, the female connection terminal 2 is inserted into the terminal receiving hole 3 by the sealing member 2b. Therefore, water does not enter the housing 1 from the female connection terminal 2 side. In addition, since the rear side of the housing 1 is sealed by the corrugated portion of the connecting body holding portion 7, there is no possibility that water may similarly enter.

Further, by fitting and fixing the rear holder 8 to the housing 1, the female connector terminal 2 is prevented from coming off by the locking portion 8 a of the rear holder 8. The rear holder 8 has a hole substantially coaxial with the terminal receiving hole 3. Before the female connection terminal 2 is inserted, the rear holder 8 is temporarily fixed to the housing 1 at a position indicated by a dotted line by a temporary fixing mechanism (not shown) so that the hole of the rear holder 8 and the terminal receiving hole 3 are coaxial. , So that the female connection terminal 2 can be easily inserted. After all the connection terminals 2 are inserted, the rear holder 8 is lifted and pushed into the housing 1 to be moved to the position indicated by the solid line, and the rear portion of the connection terminal 2 is locked by the locking portion 8a of the rear holder 8, and the housing 1 The rear holder 8 is locked.

The female connection terminal 2 is locked by the rear holder 8 of the embodiment.
However, it is needless to say that other types of locking means may be used, for example, locking means by the connection portion of the female connection terminal 2 and the connection end 4a itself.

Further, in the embodiment, the terminal connector 4 is fixed to the housing 1 via the connector holder 7, but may be directly inserted into a fitting portion provided on the housing 1. Furthermore, the shape of the connection end 4a is not limited to the tongue shape, and may be, for example, a cylindrical shape or a pin shape. In this case, it is necessary to select a shape of the connection portion of the connection terminal that matches these shapes. .

[Effects of the Invention] As described above, the joint connector according to the present invention uses a terminal connector used by cutting a bridge portion at a predetermined location, so that assembly and circuit change can be easily performed. .
