DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
This will be described in detail with reference to FIGS.

As shown in FIG. 1, a pair of legs 3, 3 projecting in the same direction are protruded from both ends of a long central portion 2 of a connector body 1 made of insulating synthetic resin. It is formed in a substantially U-shape. A plurality of (14 in this embodiment) contacts 10 are implanted in the central portion 2 of the connector main body 1 by insert molding.

In the vicinity of the distal ends of the legs 3, 3, a spike-like positioning projection 3a is provided in a protruding manner. That is, when the connector is mounted on the printed circuit board P, the positioning projection 3a of each leg 3 is fitted into a positioning hole (not shown) provided on the printed circuit board P, whereby the connector can be positioned with respect to the printed circuit board P. ing.

As shown in FIG. 1 to FIG.
Is a contact portion 12 having a pair of bifurcated contact pieces 12a, 12a at its tip made of an elastic metal material such as copper or copper alloy, and a substantially U-shaped connection portion extending from the contact portion 12. The terminal portion 11 is integrally formed with the terminal portion 11 which extends to the rear end side of the connection portion 13 and is soldered to a pattern (conductor pattern for wiring) of the printed circuit board P. The terminal portion 11 of the contact 10 is projected from the back side of the central portion 2 of the connector body 1 so that the bottom surface thereof is substantially flush with the bottom surface of the connector body 1 (the surface facing the mounting surface of the printed circuit board). .

As shown in FIG. 6, the connecting portion 13 of the connector 10 which is inserted into the central portion 2 of the connector body 1 is located inside the connector body 1 (on the side separated from the printed circuit board when the printed circuit board is mounted). ). In the following description, this portion will be referred to as a curved portion 14. Conventionally, since such a curved portion 14 was not provided, there was a case where molten solder or flux at the time of soldering the terminal portion 11 ran up from the terminal portion 11 to the contact portion 12 through the connecting portion 13. However, in the present embodiment, by providing the bending portion 14, the bending portion 14 is not exposed on the bottom surface side of the connector main body 1 as shown in FIG.
The movement path of the solder and the flux reaching the connector body 1
Almost completely shut off. As a result, it is possible to prevent the solder or the flux melted at the time of the soldering of the terminal portion 11 from moving from the terminal portion 11 to the contact portion 12 of the contact 10 through the connecting portion 13 as in the related art, thereby improving the contact reliability. Can be improved.

Further, of the connecting portion 13 of the contact 10, a portion which is not inserted into the connector body 1, that is, an opening of the connector body 1 surrounded by the central portion 2 and the two legs 3, 3 as shown in FIGS. The projecting portion is formed in a shape that curves away from the pattern forming surface of the printed circuit board on which the connector is mounted. That is,
Even if the molten solder or the flux when the terminal portion 11 is joined by solder is moved from the terminal portion 11 along the printed circuit board P, the connecting portion 13 is curved and floated from the pattern forming surface of the printed circuit board P. Therefore, the movement of the solder or the flux is blocked at this portion, and it is possible to prevent the solder and the flux from traveling along the connecting portion 13 to the contact portion 12 of the contact 10, thereby improving the contact reliability.

In order to improve the contact reliability, the contact portion 12 of the contact 10 has forked contact pieces 12a, 12a.
a is provided.
The distance between the outer end portions of the contact pieces 12a is narrower between each other, and when the pattern pitch of the mating printed circuit board is narrow as described in the conventional example, the contact piece 12a is adjacent to the adjacent pattern (or pad, hereinafter referred to as pad). The same). Therefore, in the present embodiment, as shown in FIG. 7, the contact piece of the other contact 10 is an end of a surface (hereinafter, referred to as a “contact surface”) of each contact piece 12 a that comes into contact with the pattern of the mating printed circuit board. The end (outer end) facing 12a is formed in a shape separated from the pattern of the mating printed circuit board. Specifically, a tapered surface 12b is formed at the outer end of the contact surface of the contact piece 12a.

When the contact portion 12 of the contact 10 is brought into contact with the pattern Pa on the mating printed board, as shown in FIG. 8, the contact piece 1 is formed by the tapered surface 12b.
Since the outer end of the contact surface of 2a rises from the surface of the pattern Pa of the mating printed circuit board, even if the alignment with the mating printed circuit board is shifted, the contact piece 12a of the contact 10 becomes the contact piece 12a of another contact 10. This can prevent the contact with the pattern Pa of the partner printed circuit board that makes contact with the contact, and can prevent a short circuit between the adjacent contacts 10. As shown in FIG. 8, tapered surfaces 12c, 12c may be similarly formed on the inner end of the contact 10 where the contact pieces 12a, 12a face each other.

By the way, a part of each of the holding members 20, 20 is inserted into both side surfaces of the central portion 2 of the connector body 1. The holding member 20 has the same shape as the contact 10 in which the connection portion 13 and the contact portion 12 are cut off in the middle of the connection portion 13, and the remaining terminal portion 11, the curved portion 14 and a part of the connection portion 13 are formed. Terminal part 1
1 is solder-bonded to the pattern forming surface of the printed circuit board P. The joining portions 21 and 21 of the holding members 20 and 20 inserted into the connector body 1 in this manner.
Is fixed to the printed circuit board P by soldering.
Contact 10 soldered by holding connector body 1 to printed circuit board P by holding member 20
Are reinforced. Conventionally, such a holding member was attached to the connector main body 1 by press fitting. However, as in the present embodiment, the holding member 20 is insert-molded into the connector main body 1 so that the mounting process by press fitting is performed. Therefore, the manufacturing cost can be reduced more than before.

Further, the conventional holding member has a low bonding strength because the bonding portion to be soldered to the printed board is formed flat, and as a result, the holding strength of the connector body by the holding member is also low. However, in the present embodiment, since the holding member 20 is provided with the curved portion 22 that curves in a direction away from the printed circuit board P, when the joining portion 21 is soldered, as shown in FIG. The number of solder fillets F formed at the end portions increases, whereby the bonding strength of the holding member 20 to the printed circuit board P is increased, and the connector body 1 by the holding member 20 is further increased.
Can be improved in holding strength.

Here, the plurality of contacts 10 implanted in the central portion 2 of the connector main body 1 have their contact portions 12 projecting upward from the upper surfaces of the legs 3 of the connector main body 1 as shown in FIG. I have. Thus, the contact portion 12 of the contact 10
When the counterpart printed circuit board is pressed downward, the contact 10 deformed by contacting the pattern of the counterpart printed circuit board is brought into contact with the pattern at the contact portion 12,
The contact pressure for the pattern is obtained by the elasticity of the contact 10. At this time, even when the mating printed circuit board is pressed more than necessary, the upper surfaces of the legs 3 and 3 of the connector body 1 contact the pattern forming surface of the mating printed circuit board, so that the contact 10 is not deformed more than necessary. In addition, plastic deformation and breakage of the contact 10 can be prevented.

Next, a method of manufacturing the connector according to the present embodiment will be described with reference to FIGS.

As shown in FIG. 9, a large number of contacts 10 having the above-described structure are formed on the hoop material 30 at equal intervals along the longitudinal direction. First, the hoop material 30
Is cut from the tip of a portion corresponding to the terminal portion 11, and a pair of contacts 10y and 10 sandwiched between the contacts 10x is cut.
y is cut from the curved portion 14 (22) of the connection portion 13 first.

As shown in FIG. 10, the connector body 1 includes two contacts 10y, 10y and a plurality (14 in this embodiment) of contacts 10 sandwiched therebetween.
Insert molding. At this time, the two legs 3, 3 of the connector body 1 are arranged at positions corresponding to the cut contacts 10x.

Lastly, the contact 10 and the holding member 20 are connected to the terminal portion 11 and the tip of the joint portion 21 by the hoop material 30.
The connector of the present embodiment is formed by disconnecting the connector. Therefore, portions of the contacts 10x, 10x inserted into both ends of the central portion 2 of the connector body 1 become the holding members 20,20.

According to the manufacturing method of the present embodiment, the holding member 11 is formed by cutting unnecessary portions of the plurality of contacts 10 formed at equal intervals in the hoop material 30. There is no need to form the holding member 20 on the hoop material 30 independently of the contact 10, and the manufacturing process and manufacturing cost can be reduced.
