Abstract

PURPOSE:To easily deal with every type of assembly simplification, high accu racy and further male/female, dominant differential position, etc., of a connector, in the case of intending to obtain a time dominant difference for electrically connecting the connector. CONSTITUTION:A carrier part 103, after cutting off its several kinds of carrier- provided terminals 102a, 102b, 102c with contact positions or lengths different, is combined in predetermined arrangement. The carrier part 103 is temporarily stopped by welding 105, jig, etc., and collectively press-fitted to a housing 101 by forming several kinds of the terminals of different press-fit depth into a shape of a single sheet of strip-shaped spring 104.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a connector, and more particularly to a method for assembling a connector which seeks to obtain a temporal advantage in electrical connection with a mating connector due to a difference in contact position within one connector.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a connector of this type has been constructed by press-fitting terminals 401a and 401b having different lengths into the housing 101 one by one or several pins. .

[0003]

In the above-mentioned conventional connector assembling method, when one pin or several pins are press-fitted, the contact position in one connector or the length of terminals is shortened due to the variation of the press-fitting amount. However, there is a drawback in that the difference in height cannot be obtained accurately.

Further, since the assembly is performed by press-fitting one pin at a time or several pins at a time, there is a drawback that it takes a huge amount of time to assemble the connector.

An object of the present invention is to provide a connector assembling method which can simplify the assembling of the connector and improve the accuracy.

[0006]

In order to achieve the above-mentioned object, a method of assembling a connector according to the present invention provides a method for cutting a carrier of several types of terminals having different contact positions or different lengths.
By combining the carriers in a predetermined arrangement, temporarily fixing the carriers with a jig or a jig, and forming a plurality of terminals having different press-fitting depths into a single strip shape, they are collectively press-fitted into the housing.

[0007]

[Function] Several types of terminals having different press-fitting depths are formed into one strip shape so that the terminals are press-fitted together into the housing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

(First Embodiment) FIG. 1 is a perspective view showing a first embodiment of the present invention. In FIG. 1, terminals with carrier 102a, terminals with carrier 102b,
In the terminal with carrier 102c, the carrier portion 103 is cut by the number of pins required for combination.

The terminal with carrier 102a, the terminal with carrier 102b, and the terminal with carrier 102c are fixed in a predetermined combination by welding 105 to the carrier portion 103 to form a strip spring 104 having a predetermined combination of terminal lengths. . The strip spring 104 is pressed into the housing 101 all at once.

Therefore, it is possible to set a predetermined difference in length between the terminals in the strip spring 104, and even after the strip spring 104 is press-fitted into the housing 101, a predetermined difference in contact position superiority can be accurately obtained. be able to.

(Second Embodiment) FIG. 2 is a perspective view showing a second embodiment of the present invention.

In FIG. 2, the carrier-equipped terminal 102a, the carrier-equipped terminal 102b, and the carrier-equipped terminal 102c, which have different lengths, have the carrier portion 103 cut by the number of pins required for combination.

The terminals with carrier 102a, the terminals with carrier 102b, and the terminals with carrier 102c are combined in a predetermined manner on a base plate 206 having a positioning hole 205a to position the positioning hole 205a of the base plate 206 and the carrier portion 103. After the positional accuracy is obtained by the hole 205b, the base plate 206 and the carrier portion 103 are spot-welded 207 to form a strip spring 204 with a double plate carrier.

Accordingly, it is possible to set a predetermined difference in length between terminals in the strip spring 204 with a double plate carrier without requiring high precision in cutting and welding the carrier portion 103. Strip spring with double plate carrier 2
Even after press-fitting 04 into the housing 101, it is possible to accurately obtain a predetermined difference in contact point position.

(Third Embodiment) FIG. 3 is a perspective view showing a third embodiment of the present invention.

In FIG. 3, the carrier-equipped terminal 102a, the carrier-equipped terminal 102b, and the carrier-equipped terminal 102c, each having a different length, have the carrier portion 103 cut by the number of pins required for combination.

The terminal with carrier 102a, the terminal with carrier 102b, and the terminal with carrier 102c have a holding base 3 having a positioning pin 305 and a terminal outer shape guide portion 306.
A predetermined combination is performed on the positioning pin 305.
After the positioning accuracy is obtained by the positioning hole 205b of the carrier part 103 and the terminal outer shape guide part 306, the pressing base 30
The carrier portion 103 is sandwiched between 7 and the holding plate 308 to form a strip spring 304 with a dummy carrier.

Therefore, the carrier portion 103 has the dummy carrier-attached strip spring 30 without any joining work such as welding.
4, it is possible to set a predetermined difference in length between the terminals.
Even after the press-fitting into the housing 101, it is possible to accurately obtain a predetermined contact position superiority difference.

[0020]

As described above, according to the present invention, after the carriers of several terminals having different contact positions or different lengths are cut, they are assembled in a predetermined arrangement and the carrier parts are temporarily fixed by welding or jigs. However, several terminals with different press-fitting depths are press-fitted into the housing by making them into one strip-shaped shape, so there is a time advantage in electrical connection with the mating connector due to the difference in contact position in the connector. In the connector to obtain the difference, the difference in the contact position or the difference in the length between the terminals can be improved, and one row of the housing holes can be press-fitted together with a strip spring. This has the effect of shortening the time.
