Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the internal wiring of an electrical connector containing a plurality of terminals.

In the conventional internal wiring of this type of electrical connector, the wire clamping part of one terminal and the wire clamping part of the other terminal are connected by wiring made of stranded wires with excellent flexibility. However, when the wires are wired using short twisted wires, the wires become too flexible and come out of the wire grooves, causing the twisted wires to be bitten when the lid is tightened, making the work extremely complicated.

The present invention was devised in view of the above-mentioned problems, and aims to provide an electrical connector in which internal wiring is carried out smoothly and reliably, and lid tightening is carried out simply and quickly.

Hereinafter, the present invention will be explained according to an illustrative embodiment.

A is an electrical connector that accommodates a female terminal 1 and a male terminal 2, and is assembled with a main body _A1 and a lid _A2 .

The main body A ₁ is provided with two female terminal accommodating chambers 3, 3 and two male terminal fitting parts 4, 4, and a wiring guide column 5.
, an assembly screw hole 6, and a wire guide groove 7.

The female terminal accommodating chamber 3 has a guide piece 3a upright therein into which the female terminal 1 is fitted, and a wire crimping portion 1 of the female terminal 1.
It is constructed by cutting out the guide groove 3b of a and opening the mating male terminal insertion groove 3c.

The female terminal 1 is made by bending a plate material into a substantially octopus-shaped outer shape, and has a wire crimping portion 1a on the head thereof.

Each stranded wire 8a of an electric wire 8 consisting of two stranded wires with excellent flexibility, which is a power supply wire, is crimped in the wire crimping portion 1a, and one end of a wiring 9, which will be described later, is crimped.

The wiring 9 is a single conductor having plasticity such as a single wire made of a copper conductor, and one end is crimped to the above-mentioned wire crimping part 1a, and the other end is crimped to the wire crimping part 2a of the male terminal 2. , and are guided by the guide column 5 to ensure proper placement.

The male terminal 2 has a fitting piece 2 near the wire clamping part 2a.
b protrudes, and the male terminal 2 passes through the window 4a of the fitting portion 4 of the main body _A1 and protrudes to the outside, and its fitting piece 2b fits into the fitting portion 4.

The lid _A2 has the electric wire 8 along with the electric wire guide groove 7.
The wire guide groove 7' that holds the above-mentioned male terminal insertion groove 3
A male terminal insertion groove 3c for guiding a mating male terminal, a screw hole 6' that matches the screw hole 6, and a presser foot for pressing the fitting piece 2b across the wire clamping part 2a. Pieces 10, 10 are protruding.

Next, the function of the internal wiring 9 of the present invention constructed as described above will be explained together with the assembly of the electrical connector A.

First, as shown in FIG. 3, the female terminals 1, 1 connected to each other are set in the housing chamber 3 in the main body _A1 , and the male terminals 2, 2 are passed through the fitting windows 4a, 4a. The wires 9, 9 are stacked vertically and passed between the screw hole wall 6a and the wire guide post 5, along the inner wall surface 11 of the main body _A1 , and are perpendicular to the longitudinal direction of the windows 4a, 4a. Place it like this. At this time, the wires 9, 9 maintain their arranged postures due to plastic deformation. Therefore, when the lid body A ₂ is attached to this, the holding pieces 10, 10 are attached to the caulking portions 2 of the wirings 9, 9.
a, 2a smoothly and the abutting surface 12
matches the abutting surface 12 of the main body _A1 . Then, they are fixed together using screws 6a.

In the above embodiment, one female and one male terminal are accommodated, but more terminals may be accommodated.

As described above, in the present invention, in an electrical connector that accommodates a plurality of terminals and connects the wire clamping part of one terminal and the wire clamping part of another terminal by wiring, The internal wiring of the electrical connector is constructed by connecting each wire crimping part with a wire made of a single conductor with plasticity, so once the wires are aligned at the predetermined wiring position, the main body and the lid can be connected smoothly. Wiring work and assembly of electrical connectors can be performed efficiently and accurately.
