Description

[Detailed description of the invention] <Industrial application field> This invention relates to connectors, and in particular has the function of parallel positioning when a terminal is attached to a connector housing and a confirmation display when mating a mating connector. Regarding connectors.

<<Prior Art>> As shown in FIG. 6, a conventional connector C equipped with a male terminal generally has a connector housing 1,
A plurality of male terminals 3 and each terminal 3 connected to the mating connector 2 that fits into this connector housing 1
It consists of a lead wire R connected to the rear end of the lead wire R.

The connector housing 1 has a terminal mounting part 4 in which a plurality of insertion holes 4a are arranged in a grid pattern, and the terminal mounting part 4 is enlarged one stage in front of the terminal mounting part 4 and is integrally connected to the mating connector 2. The male terminal 3 is inserted into each of the insertion holes 4a, and the tip end 3a of each male terminal 3 is inserted into the fitting part 5.
are projected in a parallel state, and are prevented from coming out by coming into contact with locking claws 6 that are integrated into each insertion hole 4a in a projecting state.

<<Problems to be Solved by the Invention>> However, with this structure, the tips 3a of the terminals 3 may not necessarily be in a parallel state, and may be fixed in an open or sandwiched state.

When the mating connector 2 is fitted into the fitting part 5 in this state, since the tip is in a free state, it does not fit properly into the female terminal (not shown) provided on the mating connector 2, and may bend or bend. This makes it easier for warping to occur, lowering the yield and causing product defects.

Therefore, in order to eliminate this type of defective product, conventionally, after the product is completed, a trial connector is inserted to determine whether it is correct or not. The condition of the terminals had to be visually checked, making the inspection method cumbersome.

This invention is intended to solve the above problems, and its first purpose is to essentially ensure that the terminal tips are properly parallel, reduce the occurrence of defects due to misalignment, and improve yield. The second objective is to provide a connector that allows easy confirmation from the outside that the terminals are correctly inserted at the time of inspection or the start of use.

<Means for Solving the Problems> In order to achieve the above object, the connector of this invention includes a connector housing in which a mating part for mating a mating connector is provided on one side of the terminal mounting part having an insertion hole. , a connector comprising a male terminal inserted into the insertion hole and fixed with the tip thereof protruding parallel to the fitting portion, an insertion guide for positioning and inserting the tip of the male terminal; A slide jig is slidably fitted to the inner wall of the fitting portion via a positioning means, and the slide jig is detected from a display portion formed in the fitting portion when the mating connector is inserted. By doing so, it is possible to detect a state in which the connectors are properly fitted to each other.

<<Operation>> According to the above structure, when the terminal is attached to the connector housing, the tip end of the terminal is inserted into the insertion guide provided on the slide jig, and the attachment is completed with the parallelism maintained correctly.

When the mating connector is fitted into the mating portion in the completed state, the slide jig is pushed by the tip of the mating connector and moves, and this movement can be detected from the display formed on the mating portion, thereby making it possible to confirm whether the connectors have been fitted correctly to each other.

<<Example>> Hereinafter, an example of this invention will be described in detail using the drawings.

1 to 3 show an embodiment of this invention.

Note that, in the configuration other than the essential parts of this invention, parts that are common or equivalent to those of the conventional example are given the same reference numerals, and only different parts will be explained using different numbers.

The connector C in the figure is almost the same as the conventional one, and includes a connector housing 1, a plurality of male terminals 3 connected to a mating connector 2 fitted to the connector housing 1, and a lead wire R engaged with the rear end of each terminal 3. It is made up of.

The connector housing 1 has a terminal mounting part 4 in which a plurality of insertion holes 4a are arranged in a grid pattern, and the terminal mounting part 4 is enlarged one stage in front of the terminal mounting part 4 and is integrally connected to the mating connector 2. The male terminal 3 is inserted into each of the insertion holes 4a, and the tip end 3a of each male terminal 3 is inserted into the fitting part 5.
are made to protrude in a parallel state, and are prevented from coming out by coming into contact with locking claws 6 that are integrated into each insertion hole 4a in a protruding state.

A slide jig 10 is slidably disposed at a substantially intermediate position within the fitting portion 5, and its upper and lower sides are provided as positioning means protruding from the upper inner surface and inner bottom surface of the fitting portion 5. It is fixed in a clamped state by positioning protrusions 11.

The amount of protrusion of each positioning protrusion 11 is relatively small;
This allows the slide jig 10 to easily lose its supporting force due to external force and move in the direction in which it is pushed.

The slide jig 10 has an outer shape that is the same as the inner shape of the fitting portion 5, and has a plurality of holes arranged in accordance with the arrangement of the terminals 3 on the rear side, that is, on the side facing the terminals 3. An insertion guide 12 is bored, and display projections 13 facing upward and downward toward the rear side are integrally formed to protrude.

Correspondingly, the fitting portion 5 and the terminal mounting portion 4
A display window 14 serving as a display section through which the display protrusion 13 can be seen is formed in the stepped portion between the two.

Reference numeral 12b indicates a guide protrusion, and the tip portion 3a of each terminal 3
The insertion guide 12 protrudes oppositely at a position corresponding to the terminal 3, and the insertion guide 12 into which the tip end 3a is inserted is bored through the insertion guide 12, and a taper 12a is formed at the opposite end to facilitate the insertion of each terminal 3. It is planned.

4 and 5 show a guide protrusion 12 on the terminal 3 side of the insertion guide 12 as in the first embodiment described above.
An example is shown in which b is not provided.

To assemble the connector C with the above configuration, as shown in Figure 1, connect the male terminal 3 to the connector housing 1.
If the rear end is press-fitted into the insertion hole 4a, the tip end 3a
is inserted into the insertion guide 12, and the slide jig 1
The locking pawl 6 engages in a state in which it penetrates back and forth through 0, and installation is completed in this state.

By repeating the above operations for the number of male terminals to be attached, the mounting operation is completed and the connector C is completed as shown in FIG.

In the completed state, the tip portions 3a of the terminals 3 are inserted and held in each insertion guide 12, supported at two points with the terminal mounting portion 4, and the tip portions 3a of each terminal 3 maintain parallelism with high precision. It turns out.

When the mating connector 2 is attached to the fitting portion 5 of the connector C in the completed state, the front surface of the slide jig 10 comes into contact with the tip of the connector 2. Further, on the front surface of the slide jig 10, the tip portion 3a of each terminal 3 is provided.
are arranged vertically and horizontally in parallel with a certain degree of precision, so they can be inserted securely into the mating connector 2.
It fits into a female terminal (not shown) and is electrically connected to each other.

Further from the abutting state, the mating connector 2
When moved forward, the slide jig 10 climbs over the positioning protrusion 11 and retreats.

When it has completely retreated, as shown in Figure 3,
The display projection 13 passes through the display window 14 and becomes flush with the stepped portion, thereby indicating that the mating connector 2 has been correctly inserted.

In addition, even if the mating connector is inserted and removed repeatedly thereafter, the base of the tip of the terminal 3 remains in the correct position by the slide jig 10, so it will not easily go out of alignment and This allows you to maintain the correct temperature.

As explained in detail in the above embodiments, in the connector of this invention, when the terminal is attached to the connector housing, the tip of the terminal is inserted into the insertion guide provided on the slide jig, and the attachment is completed with the parallelism properly maintained.

When the mating connector is fitted into the mating part in the completed state, the slide jig is pushed by the tip of the mating connector and moves, and this movement status can be detected from the display part formed in the mating part. This makes it possible to confirm whether or not the connectors have been properly fitted to each other. Furthermore, since the slide jig is slidably fitted to the inner wall of the fitting portion via the positioning means, it is possible to prevent the slide jig from moving unnecessarily.

Therefore, with this invention, the parallelism of the tips of the terminals can essentially be maintained correctly, reducing the occurrence of defects due to misalignment, and improving the yield.

In addition, this device allows you to easily confirm from the outside through the display whether the terminal is correctly inserted during inspection or when starting use, making it easy to inspect the completed product or confirm when it is first inserted. It can be carried out.
