Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connector,

The present invention relates to a connector and a method for assembling the same.

A connector is an electric component for connection of a substrate and / or a wire. Such a connector may include a housing made of an insulating material and at least one terminal fixed to the housing. In general, the terminal is integrally fixed to the housing by insert injection or the terminal is press-fitted and fixed.

However, when the terminal is injected into the housing, the position of the terminal may be restricted. For example, when a plurality of terminals are arranged in two rows in the vertical direction, the terminals arranged in two rows in the vertical direction must be positioned so as not to overlap each other in the direction in which the mating connector is inserted, The insertion of the core becomes possible. In recent years, however, depending on the width of terminals and the distance between the terminals required in specifications and specifications, a part of the terminals in the upper and lower rows may be positioned to overlap the front and rear of the connector. As a result, in such a case, it becomes impossible to fix the terminal to the housing by insert injection. Therefore, when a terminal is press-fitted into the housing, a plurality of terminals must be press-fitted into the housing. In this case, the number of operations increases and molding, i.e., bending is not easy.

A plurality of upper terminal seating grooves 13 and lower terminal seating grooves (not shown) are formed on the upper and lower surfaces of the coupling protrusion 11, respectively. The first and second terminals 1 and 2 are seated in the upper terminal seating groove 13 and the lower terminal seating groove. The upper terminal seating groove 13 and the lower terminal seating groove are elongated in the longitudinal direction of the coupling protrusion 11 in the XYZ coordinate system, that is, in the X axis direction X, That is, in the Z-axis direction Z.

At least one press-fit hole (15) is formed in the housing (10). The press-fitting hole 15 is formed on the opposite side of the front surface of the housing 10 on which the coupling protrusion 11 is provided, that is, on the rear surface of the housing 10. The press-fit hole (15) substantially opens in the X-axis direction (X) at the rear surface of the housing (10).

The first terminal 1 includes a part of the upper terminal located on the upper surface of the coupling protrusion 11 and a lower terminal located on the lower surface of the coupling protrusion 11.

The first upper terminal 110 and the first lower terminal 120 are referred to as an upper signal terminal and a lower signal terminal and the second upper terminal 210 and the second lower terminal 130 are referred to as an upper power terminal and a lower signal terminal, It may be referred to as a power terminal.

The first upper terminal 110 may be seated in the rest of the upper terminal seating grooves 13 except for the outermost side in the Z-axis direction Z. The second upper terminal 210 may be seated on the outermost side of the upper terminal seating groove 13 in the Z-axis direction Z, respectively. In addition, the first lower terminal 120 may be seated in the rest of the lower terminal seating grooves except for the outermost side in the Z-axis direction Z, corresponding to the first upper terminal 110. The second lower terminal 130 may be seated at the outermost side of the Z-axis direction Z among the lower terminal seating grooves.

On the other hand, the first terminal 1 includes a first contact portion, a first extending portion, and a first lead portion, respectively. That is, the first upper terminal 110 includes a first upper contact portion 111, a first upper extension portion 112, and a first upper lead portion 113, and the first lower terminal 120, The second lower terminal 130 includes a first lower contact part 121 and a first lower extension part 122 and a first lower lead part 123.

The first upper extension portion 112 extends in the Y-axis direction Y at one end of the first upper contact portion 111. The first upper lead portion 113 extends in the X axis direction X so as to face the first upper contact portion 111 at the first upper extension portion 112. The first lower contact portion 121 and the first lower contact portion 122 and the first lower contact portion 123 and the second lower contact portion 131, The lower lead portion 133 may extend in the same direction as the first upper contact portion 111, the first upper extension portion 112 and the first upper lead portion 113. However, the first lower lid part 123 and the second lower lid part 133 may be seated in the lower terminal seating groove.

The second terminal 2 and substantially the second upper terminal 210 include a second upper contact portion 211, a second upper extension portion 212 and a second upper lead portion 213 . The second upper contact portion 211 extends in a direction parallel to the X-axis direction X and is substantially seated in the upper terminal seating groove 13. The second upper extension portion 212 extends in the Y-axis direction Y at one end of the second upper contact portion 211.

Further, the second upper terminal 210 is press-fitted into the housing 10 through the press-fit hole 15 and fixed.

In recent years, there has been a tendency that the size of the second upper terminal 210, especially the width in the Z-axis direction Z, has to be designed in order to secure the electrical characteristics according to the design conditions do. In other words, the width of the second upper terminal 210 is required to be a predetermined value. However, when the size of the connector as a whole is reduced, the second upper terminal 210 is connected to the second lower terminal 130 In particular, it can be positioned so as to overlap at least in the X-axis direction (X). However, in order to fix the terminal integrally to the housing 10 by insert injection, a core must be inserted between each terminal in the X-axis direction X. [ Therefore, in such a case, generally, the entirety of the terminal was fixedly press-fitted into the housing 10.

However, in this embodiment, since the second upper terminal 210 is fixed to the housing 10 integrally with the remaining terminals by insert injection, the housing 10 is press-fitted and fixed, The terminals other than the terminal 210 may be integrally fixed to the housing 10 by insert injection. Therefore, in the present embodiment, even when the second upper terminal 210 is positioned so as to overlap with the second lower terminal 130 in the X-axis direction X, The terminal can be integrally fixed to the housing 10 by insert injection.

Hereinafter, a method of manufacturing a connector according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
