Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector housing having a novel structure that prevents rattling of electric wires inserted into the housing and connected to terminal fittings, and also provides a heat dissipation effect.

An embodiment of the present invention will be described below with reference to the drawings.
A is a female connector housing, which has a plurality of terminal accommodating chambers A1 at the rear and a common sleeve A2 at the front.

B is a male terminal fitting, which has a wire connection part B1 at the rear and a male tab-shaped electrical contact part B at the front.
An electric wire 1 is connected to.

A flexible locking arm 2 is provided in each terminal accommodating chamber A1, and a locking protrusion 3 at the free end of the flexible locking arm 2 engages with a retaining hole 4 of the terminal fitting B.

The terminal accommodating chamber A1 has a rectangular shape, and a series of protrusions 5 oriented in the axial direction are provided at its four corners. The recess 6 is formed in the axial direction so that the heat generated in the housing is not trapped inside the housing.

The recess 6 has an L-shaped groove 6a in a portion of the outer circumference of the connector housing A where the terminal accommodating chamber A1 is not adjacent.
In each part where the two terminal accommodating chambers A1 are adjacent to each other, there is a U-shaped groove 6b that is open to the outside, and in a part other than the outer peripheral part of the connector housing A, that is, in the terminal accommodating chamber A
The four pieces 75 of 1 have holes 6c in the contacting part of the button.

A protrusion 5 buttoned and adjacent to the inside of the connector housing
, 5 is the external cross-shaped groove 6a.
and the U-shaped groove 6b.

Since the present invention is constructed as described above, the plurality of protrusions provided at intervals within the terminal accommodating chamber act to prevent the electric wire connected to the terminal fitting from wobbling, thereby making the electrical connection. It works to maintain the stability of the terminal, and also achieves a good heat dissipation effect with the groove-shaped recesses provided indoors and outdoors, and has the effect of improving various defects caused by heating of terminal fittings. have

Claims (1)

[Scope of utility model registration request] In a connector housing having a plurality of protrusions extending in the axial direction inside the terminal accommodating chamber, each portion adjacent to the terminal accommodating chamber has a U-shaped groove-like recess for accommodating the terminal. Room 7! In the part that does not come into contact with the J, an L-shaped groove-like recess is provided on the outer circumferential surface at a position corresponding to the protrusion, and the internal groove formed between adjacent protrusions forms the outer groove-like recess. A connector housing characterized by being located between recesses.
