[0006]

[Problems to be Solved by the Invention] However, in the case of mass-producing connectors at low cost, it is necessary to reduce the number of parts as much as possible and reduce the man-hours required for assembly. Also, in the assembly, it took a lot of time and labor to attach the reinforcing metal fittings and jigs.

Therefore, the technical problem of the present invention is to eliminate the conventional drawbacks and to provide a low-cost connector suitable for mass production that has a small number of parts and does not require assembly steps.

[0008]

[Means for Solving the Problems]

 According to the present invention, a plurality of contacts arranged in parallel, each of which is composed of a long conductor piece, a pair of insulators holding both ends of the contacts in the longitudinal direction, and an outside of the insulator in the pitch direction of the contact And a reinforcing member formed so as to be bonded to the substrate, the reinforcing member being substantially equivalent to the contact partially cut between the pair of insulators. A surface mount type connector is obtained.

According to the present invention, in the surface mount type connector, both ends of the reinforcing member are projected from the insulator, and both ends are formed so as to be solderable to the substrate. A characteristic surface mount connector is obtained.

[0010]

[Action]

 In the present invention, the contact and the insulator are integrally formed, and the contact and several ends in the pitch direction are used. The middle part of the contact on both sides of the insulator facing each other can be cut and the remaining portion can be soldered to the substrate. By molding in this way, it can serve as a reinforcing material. Since the contact is used and the reinforcing member is used, the number of parts can be reduced. In addition, the reinforcement member can be formed at the same time as the contact.

【Example】

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

FIG. 1 is a perspective view of a connector according to an embodiment of the present invention.

In FIG. 1, a pair of contacts 1 ₁ , 1 ₂ , ..., 1 _n that penetrates a pair of prismatic insulators 2 and 2 and is composed of n (where n is a natural number) long conductive pieces. Are provided at equal pitches, and the projecting portions of the projecting ends 1 _1a , 1 _2a , ... 1 _na are bent downward and extend downward, and further bent upward and away from the insulators 2 and 2. To form a joint. To each of the insulator 2, 2, the contact ₁ 1, 1 _2, ... on both sides of 1 _n, the contact ₁ 1, 1 _2, parallel to ... 1 _n, the contact ₁ 1, 1 _2, ... 1 _n reinforcing bracket 3 _a made of a material of the same type, 3 _b is held with. Protruding ends of the reinforcing bracket 3 _a, 3 _b is an insulator 2,2 sides, symmetrically with each other, the bent downwards at the side of the insulator 2, 2, bend folded upwards beneath, insulators 2,2 It extends away from. Each of the insulators 2 and 2 is formed by stacking _a pair of insulating plates 2 _a and 2 _b , respectively. Connector 10, leaving the ends of the contact protruding part between the pair of insulating plates 2 _a, 2 _b, and is formed further, the protruding portion of the reinforcing bracket 3 _a, 3 _b sandwiched by residual. To prepare a connector 10, the conductor pieces of the same type and n + 4 pieces prepared, respectively sandwiched by and held at both ends insulating plate 2 _a, 2 _b, cutting both sides of the con tact. At this time, both ends of the contact that have not been cut and protruded to the outside are bent to form joints, and the remaining parts at both ends of the cut contacts are used as reinforcing metal fittings, as in the case of the bent contacts. The part may be bent, and the part of the reinforcing metal fitting protruding from the insulator may be bent as well. To mount the connector on the board surface, the contact tips and the tips of the reinforcing metal fittings may be soldered as joints.

In FIG. 2, the joint surfaces of the upper insulator 2 and the lower insulator 2 intersect with each other, and the connector fixed to the substrates 4 and 4 receives a force in the deformed direction 5. Although it works, it is held by the reinforcing metal fittings 3a and 3b, and has a role of reducing the load on the soldered portions of the protruding end portions 1 _1a , 1 _2a , ... 1 _na of the contacts. The reinforcing metal member plays a role of preventing the connector from peeling when a force is applied in the direction of peeling the connector from the board.

However, the outer ends 13a and 13a 'of the reinforcing metal fittings 13 and 13' are bent downward and further bent inward so that the tip of the reinforcing metal fitting is located at the tip of the groove 12c. This is different from the first embodiment. The other end of the insulator and the contact of the other insulator (not shown) connected with the contact and the reinforcing metal member are also formed in the same manner. The joint with the substrate is a half joint similar to the first embodiment.
