Description

Detailed Description of the Invention (A) Field of the Invention The present invention relates to a connector used, for example, in a wiring connection between electronic devices, and more particularly, to a method for manufacturing a connector with high assembly efficiency. method.

(B) Background of the Invention Conventionally, when manufacturing this type of connector, a large number of contacts, each having an electrode connection portion at one end and a terminal for connecting a printed circuit board at the other end, are attached to a housing. is formed and formed.

However, when installing these contacts, the contacts are formed in advance into various contact shapes that are adapted to each mounting part of the housing, and then the individual contacts are fitted by engaging with the contact mounting part of the housing. (For example, Japanese Utility Model Application Publication No. 53-110480).

However, in this case, many types of contacts are required for each mounting part of the housing, which requires a corresponding number of contact molds, which is uneconomical. The contact corresponding to the mounting position must be selected and mounted, which reduces assembly efficiency, and is not suitable for automatic assembly since many types of contacts must be handled.

(c) Purpose of the Invention Therefore, the object of the present invention is to provide an economical and efficient method of manufacturing a connector by commonly using contacts of the same shape.

(D) Summary of the Invention This invention provides a contact having an electrode connection portion at one end and a terminal for connecting to a substrate at the other end.
Insert and engage each contact support hole of the provided housing,
A method for manufacturing a connector in which the terminals of the inserted contacts are brought out to the outside, bent and engaged with bending guide grooves carved on the flat surface of the outer wall of the housing, and the terminals of the contacts are bent and guided in the same direction. characterized by something.

(E) Effects of the Invention According to the present invention, since the contacts are inserted into and fitted into the plurality of contact support holes formed in the housing, one type of contact can be used in common.

Therefore, a connector can be configured with one type of contact and a housing, reducing the number of molds and manufacturing man-hours to ensure cost reduction, and there are no restrictions on the mounting position of these contacts on the housing. This eliminates the need for selection work when installing contacts, improving assembly efficiency.

Furthermore, the terminals of contacts 1 to 1 led out of the housing can be engaged with bending guide grooves carved on the flat surface of the outer wall of the housing, so that each contact can be bent in the same direction. Therefore, the bent terminals are aligned and bent in the - row at the same plane position.

Therefore, the space at the bending part is reduced, the terminal arrangement area is compacted, the mounting area relative to the printed circuit board is reduced, the connector can be efficiently miniaturized, and the bending position can be reduced. Since it is on the same plane, it is suitable for automatic assembly.

(f) Examples of the invention An embodiment of the present invention will be described in detail below based on the drawings.

The drawings show a connector, and in FIGS. 1 to 6, this connector is composed of eight contacts 11 . . . , a housing 12, and a contact cover 13.

The above-mentioned contact 11 has a female electrode connection part 14 at one end of the conductive shaft, and a small-diameter board connection terminal 1 at the other end.
5, and this contact 11 is attached to a housing 12, which will be described later.

The housing 12 described above is made of a synthetic resin material and has a square shape, and contact support holes 16 corresponding to the numbers 1 to 1 are arranged in a concentrated manner in a circumferential manner in the center of the side surface of the square shape. The contacts 11 of the same type described above are inserted and mounted into these contact support holes 16 (eight in the figure).

This contact support hole 16 has a contact 1 on one end surface side.
It has a locking step part 17 on the inside that locks the electrode connection part 14 of the contact 11, and this locking step part 17 locks the stepped part 18 of the electrode connection part 14 of the inserted contact 11. to prevent it from coming out.

The other end side of the inserted contact 11 is led out to the outer end surface side of this housing 12, and the led out terminal 1
5 is bent and guided along a bending guide groove 19 carved in the outer end surface of the housing 12 on the side where the housing 12 is led out.

The bending guide grooves 19 are carved in correspondence with the contact support holes 16, and the negative side communicates with the end of the contact support hole 16, and the other side communicates with the ends of the contact support holes 16 so that the bending guide grooves 19 do not intersect with each other. , are carved diagonally downward and communicated with the vertical notch surface 20. This vertical notch surface 20 is a bending guide surface for bending the terminal 15, which is fully engaged and in an inclined state, directly downward in order to connect it to the printed circuit board. The notch positions of each vertical notch surface 20 are set at regular intervals with respect to the bend arrangement direction so that the intervals between the terminals 15 are the same.

As a result, the terminal 15 of each contact 11 led out
... are bent and guided downward on the same plane, arranged at regular intervals and in -rows.

Each terminal 15 protrudes downward in a line,
After being cut to a certain protruding length, the contact 1-cover 13 is fitted onto these terminals 15.

In the contact cover 13 described above, the shadow cover 13 is bent by the locking claws 21.21 provided on both sides engaging with the four engaging parts 22.22 formed in notches on both sides of the housing 12. A large number of terminals 15 . . . are press-coated and integrally fitted into the housing 12 . In the figure, 23 is a flux prevention groove.

When manufacturing a connector configured in this way, first,
As shown in FIG.
One type of contacts 11 of the same shape are inserted into the support holes 16 from one end surface side of the housing 12, and each of the inserted contacts 11 is inserted into the housing 12.
The terminals 15 of the contact 11 protrude outside from the other end surface side, and the protruding terminals 15 are bent and folded along the bending guide grooves 19, respectively, as shown in FIG. Further, as shown in FIG. 5, the bent terminals 15... are bent downward along the vertical notch surfaces 20..., and the free ends of each bent terminal 15... are cut to a certain length. After cutting them in parallel, the connector can be assembled by fitting the contact cover 13 to cover the bent portions of the terminals 15, as shown in FIG.

In this case, by aligning the bending direction of the terminals 15 every few terminals and folding them on the same plane, the bending work is simplified and automatic assembly becomes possible.

7 and 8 show another embodiment of the present invention, in which a female type electrode connection portion 72 of a contact 71 is used, and such a male type electrode connection portion is used. 72
A connector having a female electrode connection portion 1/1 as in the above-mentioned embodiment may be selected and used depending on the usage conditions.

As mentioned above, one type of contact i- is commonly used,
Since the connector is attached to the housing and bent on the same plane of the housing, the number of manufacturing steps can be reduced, assembly efficiency can be reliably improved, and the connector can be manufactured at low cost.
