Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a branch connector having a function of branching electric wires, which is used by interposing wire assembly (wire harness) etc. for automobiles.

BACKGROUND ART Conventionally, in order to form a branch circuit on an electric wire, as shown in Fig. 4, electric wire a is stripped and conductor b is
is exposed, and conductor e of branch wire d is connected by caulking piece c.
Alternatively, as shown in Fig. 5, terminal fittings f are crimped and connected to the ends of electric wire a and branch electric wire d, respectively, and these are arranged centrally within connector g. A branch circuit is constructed by a bus bar i provided on a removable cover h, and as shown in FIG.
j′ is used to construct a branch circuit by spanning between two terminal fittings in the connector (Utility Model No. 55-
75981).

In the above, in the intermediate branching method shown in Fig. 4, it is impossible to perform the work using automatic machines and the work must be done manually, resulting in poor workability, and in the connector concentration method shown in Fig. 5, busbars, covers, etc. It is necessary to prepare a new part, which increases the cost due to an increase in the number of parts, and the structure using the annular metal fitting shown in FIG. 6 has the disadvantage that the terminal fittings that can be short-circuited are limited to a small area.

Problems to be Solved by the Invention The present invention was developed with a focus on the above-mentioned points, and by using a simple conductive plate within the connector, it is possible to easily connect branch circuits between multiple terminals. It is designed so that it can be configured.

Means for Solving the Problems In order to achieve the above object, in the present invention, a terminal is inserted and locked into a plurality of terminal accommodating chambers of a connector housing, and a male tab-shaped electrical contact portion of the terminal is A configuration was adopted in which the through holes of a conductive plate having through holes corresponding to a plurality of terminal accommodating chambers were press-fitted into the through holes and brought into pressure contact with cut and raised spring pieces.

Embodiment In FIG. 1, A is a female connector housing that accommodates a male terminal B, and C is a male connector housing that accommodates a female terminal D.

The male terminal B is the wire connection part 1 that connects the wire W by caulking.
and a male tab-shaped electrical contact part 2. The male terminal B is housed in the terminal accommodating chamber 3 located in the latter half of the female connector housing A in a state where it is prevented from coming off by the flexible locking arm 4 and the projection 5, and the electrical contact portion 2
protrudes forward from the terminal accommodating chamber 3 and is located within the housing portion 6.

7 is a conductive plate made of a relatively thin metal plate, and a through hole 7a smaller than the thickness of the male tab-shaped electrical contact portion 2 is provided in a portion corresponding to the pitch dimension of the terminal accommodating chamber 3 of the female connector housing A. is formed by a cut and raised spring piece 7b.

The conductive plate 7 is pushed into the housing part 6 in a state where the required number of poles are connected, and the male tab-shaped electrical contact part 2 is press-fitted into the through hole 7a, and the male tab-shaped electrical contact part 2 is pressed into the through hole 7a. It is attached while being supported by the tab-shaped electrical contact part 2, and the spring piece 7b ensures electrical connection with the electrical contact part 2.

In the embodiment shown in FIG. 2, the conductive plate 7' is already installed at the inner end of the sleeve part 6' of the female connector housing A', and is supported by engaging the cut and raised locking pieces 8 with the protrusions 9. has been done. In this state, the male terminal B' is inserted into the terminal accommodating chamber 3', and the male tab-shaped electrical contact portion 2' is press-fitted into the hole 7a' and locked by the flexible locking arm 4'. A protrusion 10 is formed on the electrical contact portion 2' and engages with the spring piece 7b' to perform double locking.

Effects of the Invention As described above, the present invention inserts and locks a terminal into a plurality of terminal accommodating chambers of a connector housing, and connects the male tab-shaped electrical contact portion of the terminal to a through hole corresponding to the plurality of terminal accommodating chambers. The conductive plate is press-fitted into the through-hole of the conductive plate and brought into pressure contact with the cut and raised spring pieces. It has the feature that a branch circuit can be easily constructed between the terminals of the terminal.
