Description

[Detailed Description of the Invention] The present invention relates to a connector, and in particular, the terminal locking means has been improved to reduce the size of the connector.

As a connector of a type in which terminals are locked with a spacer, a connector as shown in FIG. 1 has been proposed.

In this case, a lock chamber having a locking elongated hole C is provided upright on both rear sides of the upper outer circumferential wall of the housing A, and in this lock chamber,
Insert the flexible locking arms e standing on both sides of the spacer B, engage the protrusions f with the long locking holes c, and connect the housing A with the flexible locking arms e. This locks B.

Note that d is a terminal locking piece corresponding to the plurality of terminal accommodating chambers a.

According to the above structure, the lock chamber, that is, the spacer locking portion protrudes from the outer surface of the housing A, and the locking arm e of the spacer B also protrudes.

As a result, the outer dimensions of the connector become large, which not only does not meet the demand for smaller and lighter connectors, but also has a structural drawback in that the locking arm e breaks due to external force.

This invention was made in order to eliminate the disadvantage of being bulky.
The purpose of the present invention is to provide a connector that is structurally strong and suitable for miniaturization by improving terminal locking means.

Hereinafter, the present invention will be explained based on the drawings. In FIGS. 2 and 3, 1 is a housing, 10 is a spacer, and the housing 1 is configured as an M housing in the drawings.

That is, the outer circumferential wall 2 of the housing 1 is provided with a locking arm 3 for a female housing 28, which will be described later, and protective walls 4 located on both rear sides of the arm 3.

Further, a plurality of terminal housing chambers 5 arranged in parallel inside the housing 1 are provided with flexible locking arms 6 for the terminals 21,
Furthermore, a slit is provided on the rear side of the partition wall γ between adjacent terminal accommodating chambers to form a spacer accommodating chamber 8.

The above structure of the housing 1 is the same as the conventional one, but in the present invention, a locking pawl 9 as a spacer locking portion is provided on the outer peripheral wall 2 and the rear edge facing the spacer storage chamber 8. .

First, the spacer 10 has a flat plate shape, and includes a terminal locking part 12 at the front of a plate-shaped main body 11 made of synthetic resin, and a housing locking part 13 at the rear.

In the illustrated example, the terminal locking portion 12 is provided with a plurality of terminal locking pieces 14 having protrusions 15 on the lower surface in a comb-teeth shape in correspondence with each terminal accommodating chamber 5 .

On the other hand, the housing system stopper 13 has two parts on both sides of the main body 110.
A nine-flexible locking arm 17 with a projection 18 on its upper surface is provided with a strip slit 16.16.

Figure 4 A1 shows other embodiments of the spacer,
By connecting the two locking arms 17 with a bridge 19, the locking arm 1T is reinforced and engagement and release operations with fingers or the like are facilitated.
7 are combined into one piece to make it thicker, and instead of the plurality of terminal locking pieces 14, a series of terminal holding plates 20 are used. The depth of the terminal is so long that the tip of the terminal holding plate 20 directly engages with the terminal 21.

Next, to explain how to use it, when the terminals 21 are inserted into each terminal accommodating chamber 5 of the housing 1 as shown in FIG.
The protrusion 6' of the flexible locking arm 6 enters the locking hole 23 provided in the base plate portion 22, and the terminal 21 is first locked.

Next, when the spacer 10 is inserted into the spacer accommodating chamber 8 of the terminal accommodating chamber 5, the protrusion 15 of the terminal locking piece 14 abuts against the rear wall 25 of the protective frame 24 formed on both sides of the terminal 21. The protrusion 18 of the locking arm 17 engages and locks with the locking claw 9 of the spacer storage chamber 8, and the second locking of the terminal 21 is performed, thereby ensuring that the terminal is not removed and loose. can be suppressed to

In this way, when the housing 1 into which the terminals 21 and the spacers 10 are inserted is inserted into the female housing 28 which is fitted onto the end of the printed circuit board 27, the terminals 210, the board portion 22
A folded elastic contact plate 26 formed in front of the board is bent as shown by the two-dot chain line and comes into elastic contact with the printed circuit board 21.

On the other hand, the projection 3' of the locking arm 3 of the housing 1 engages with the projection 28' of the male housing 28, and both housings 1.28 are locked.

In the above configuration, the terminal 21 is doubly locked by the locking arm 6 in the terminal storage chamber 5 and the spacer 10, so even when used in a traveling device such as an automobile, the terminal is stable without deviation or wobbling. An electrical connection is made.

The terminal locking portion 11 and the housing locking portion 12 of the spacer 10 are both formed into a flat plate shape, eliminating the risk of the housing locking portion being damaged as in the conventional case. Since the spacer retaining portion is also formed on the inside facing the spacer storage chamber 8, there is no protruding portion in the external appearance of the connector as a whole, and the connector can be miniaturized.
