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 for obtaining a temporal superiority in electrical connection with a mating connector due to a difference in a contact position within one connector.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, this type of connector employs a method in which terminals 401a and 401b having different lengths are press-fitted into a housing 101 one pin or several pins at a time. .

[0003]

In the above-described conventional connector assembling method, when one pin or several pins are press-fitted, the contact positions within one connector or the lengths of the terminals are varied due to variations in the press-fit amount. There is a drawback that the difference in height cannot be obtained accurately.

[0004] Further, since assembly is performed by press-fitting one pin or several pins at a time, there is a drawback that an enormous amount of time is required for assembling the connector.

An object of the present invention is to provide a connector assembling method capable of simplifying the assembly of a connector and achieving high precision.

[0006]

In order to achieve the above object, a method for assembling a connector according to the present invention comprises the steps of cutting a carrier for several types of terminals having different contact positions or different lengths.
A plurality of terminals having different press-fitting depths are combined into a predetermined arrangement, temporarily fixed with a jig or a jig, and formed into a single strip shape so that the terminals are collectively press-fitted into the housing.

[0007]

A plurality of terminals having different press-fitting depths are formed into a single strip shape, and are collectively press-fitted into the housing.

[0008]

Next, the present invention will be described with reference to the drawings.

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

[0010] The carrier terminal 103a, the carrier terminal 102b, and the carrier terminal 102c are temporarily fixed by welding 105 to the carrier portion 103 in a predetermined combination to form a strip spring 104 having a predetermined combination of terminal lengths. . The strip spring 104 is press-fitted into the housing 101 at one time.

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

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

In FIG. 2, the terminal 103a with a carrier, the terminal 102b with a carrier, and the terminal 102c with a carrier, 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, and the positioning hole 205a of the base plate 206 and the positioning of the carrier portion 103 are performed. After the positional accuracy is obtained by the holes 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.

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

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

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

The terminal 102a with a carrier, the terminal 102b with a carrier, and the terminal with a carrier 102c are formed by a holding table 3 having a positioning pin 305 and a terminal outline guide 306.
07, a predetermined combination is performed, and positioning pins 305
And the positioning hole 205b of the carrier part 103 and the terminal outline guide part 306 to improve the positional accuracy.
The carrier portion 103 is sandwiched between 7 and the holding plate 308 to form a strip spring with dummy carrier 304.

Therefore, the carrier portion 103 can be mounted on the strip spring 30 with a dummy carrier without performing connection work such as welding.
4, it is possible to set a difference in length between predetermined terminals.
Can be accurately obtained even after press-fitting into the housing 101.

[0020]

As described above, according to the present invention, after cutting the carriers of several types of terminals having different contact positions or different lengths, the carriers are assembled in a predetermined arrangement, and the carriers are temporarily fixed by welding or jigs. Since several types of terminals with different press-fitting depths are formed into a single strip shape, they are collectively press-fitted into the housing. Therefore, there is a time advantage over the electrical connection with the mating connector due to the difference in the contact position within the connector. In the connector for which the difference is to be obtained, the difference in the contact position or the difference in the length between the terminals can be made more accurate, and one row of the housing holes can be press-fitted with a strip spring at a time. This has the effect of shortening the time.
