CONSTITUTION:After male terminals 201, 203 with non-soldered connections 202 are pressed into a housing 102, a recessed portion 103 located on the bottom of the housing 102 and a press-in jig 401 with the step portion 402 at the end, located corresponding to the recessed portion 103, are used to press the male terminals 201, 203 until the shoulder portions 204 are buried into the recessed portion 103 and to drive it into a printed board 301.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector and a method for assembling the same, and more particularly, to a connector which intends to obtain a significant time difference in electrical connection with a terminal of a mating connector due to a difference in terminal length within one connector. The present invention relates to simplification and high accuracy of the assembly.

[0002]

2. Description of the Related Art Conventionally, a connector of this type has a male terminal having a different length press-fitted by one pin or several pins and driven into a printed board by using a press-fitting jig having no step at the tip, or before press-fitting. After determining the length of the male terminal, the male terminals were press-fitted at once and then punched into the printed board using the press-fitting jig.

[0003]

In the above-mentioned conventional connector, since the male terminal is press-fitted into the housing by one pin or several pins, there are many man-hours for making terminals having different lengths and man-hours for press-fitting. There was also a problem with accuracy. In addition, if the length of male terminals is determined before press-fitting and then press-fitting all together, there is no problem if the model is one type. There was a problem that a model for making decisions was needed.

[0004]

A connector of the present invention comprises a plurality of solderless joints which are press-fitted into a printed board and are solderlessly connected, and shoulder portions which are pressed by a press-fitting jig, and have a plurality of equal lengths. A terminal and a housing for supporting the plurality of terminals by aligning and supporting the plurality of terminals at predetermined positions, each of the plurality of terminals having a recess in the inner bottom surface of which a position in the press-fitting direction of the shoulder portion can be arbitrarily set, When the plurality of terminals are press-fitted into the printed board by the press-fitting jig, the difference between the press-fitting lengths of the terminals is arbitrarily set within the depth of the recess of the housing so that the terminals of the opposing connector are This is a configuration capable of obtaining a significant time difference in the electrical connection of.

In the connector assembling method of the present invention, a plurality of terminals each having a length equal to each other and having a solderless connection portion which is press-fitted into a printed board and connected without soldering and a shoulder portion which is pressed by a press-fitting jig are predetermined. After being press-fitted together into a housing having a concave portion on the inner bottom surface and aligned at a predetermined position, the plurality of terminals are arranged by a press-fitting jig having a step at the tip corresponding to the concave portion of the housing, which is arranged at a predetermined position of the printed board. Of each of the shoulder portions is pressed at a depth corresponding to the step until it is embedded in the concave portion, and the plurality of terminals are press-fitted into the printed board.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the connector of the present invention. The connector 101 has a housing 102 having a recess 103 on the bottom surface, and a male terminal 201 having a portion (solderless connection portion 202) for solderless connection with a printed board.
Has been press-fitted.

Next, referring to FIG. 2, description will be made on a state in which a difference in length of male terminals can be obtained so that a significant difference in time can be obtained in electrical connection after being driven into a printed board. After the connector 101 is temporarily press-fitted into the printed board 301 to be in the state of FIG. 2 (A), the concave portion 103 on the bottom surface of the housing 102 having at least the difference in length of the male terminals to be obtained, A press-fitting jig 401 having a stepped portion 402 at the tip, which has an amount of difference in the length of the male terminal that is likely to correspond to the recess 103 in position.
Is used to drive the printed circuit board 301, but the force with which the housing 102 holds the male terminal 201 is smaller than the force with which the solderless connection portion 202 of the male terminal 201 is driven into the printed circuit board 301. The male terminal 203, which tries to obtain a significant time difference in the mechanical connection, moves toward the press-fitting jig 401, and the shoulder portion 204 causes the step portion 40 at the tip of the press-fitting jig 401.
2 and the driving progresses in that state, resulting in the state of FIG. 2 (B).

[0009]

As described above, the connector of the present invention is provided with a plurality of terminals of the same length that can be solderlessly connected to a printed board and a housing having a recess on the bottom surface.
When assembling the terminals, after press-fitting the terminals into the housing all at once, using a press-fitting jig with a step at the tip corresponding to the recess of the housing, the shoulders of the terminals are pressed and driven into the printed board. Therefore, the man-hours for press-fitting the terminal into the housing can be significantly reduced, the press-fitting accuracy can be improved, and the shape of the press-fitting jig can be changed to obtain a significant time difference in all electrical connections. This has the effect of being able to deal with the amount of difference in position and length.
