Abstract

An ultrathin connector that is easy to assemble has a base in which a plurality of positioning concavities are provided side by side in a lower surface thereof, connection terminals having a shape obtained by bending a needle-like metal material in two and joining it under pressure, these connection terminals being positioned in the positioning concavities so that two free end portion project from the base, a pressure-sensitive adhesive tape that is pasted on, and integrated with, the lower surface of the base and fixes the connection terminals to the base, and a control lever in which a pair of rotary shafts that protrude coaxially from the end surfaces on both sides are rotatably supported on the base and which lifts wider portions of the connection terminals.

Claims

1. A connector comprising:

a base in which a plurality of positioning concavities are provided side by side in a lower surface thereof;

connection terminals having a shape obtained by bending a needle-like metal material in two and joining it under pressure, these connection terminals being positioned in said positioning concavities so that at least one free end portion projects from said base;

a tape cover that is pasted on, and integrated with, the lower surface of said base and fixes said connection terminals to said base; and

a control lever in which a pair of rotary shafts that protrude coaxially from end surfaces on both sides are rotatably supported on said base and which lifts one free end portion of said connection terminals.

2. The connector according to claim 1, wherein positioning is performed by causing a rotation fulcrum formed by caulking in the vicinity of the bent portion of the connection terminal to abut against a reference surface provided inside the positioning concavity of the base.

3. The connector according to claim 1, wherein a pair of elastic arm portions are extended parallel to each other in the same direction from end surfaces on both sides of the base, and the rotary shafts of the control lever are rotatably engaged with respective bearing portions provided at the distal ends of said elastic arm portions.

4. The connector according to claim 2, wherein a pair of elastic arm portions are extended parallel to each other in the same direction from end surfaces on both sides of the base, and the rotary shafts of the control lever are rotatably engaged with respective bearing portions provided at the distal ends of said elastic arm portions.

5. The connector according to claim 3, wherein a taper surface facilitating the assembly of the control lever is formed at the distal end surface of the elastic arm portion.

6. The connector according to claim 4, wherein a taper surface facilitating the assembly of the control lever is formed at the distal end surface of the elastic arm portion.

7. The connector according to claim 1, wherein

the rotary shafts of the control lever are rotatably mated with support clasps that are engaged with and fixed to the end surfaces on both sides of the base.

8. The connector according to any one of claim 2, wherein

the rotary shafts of the control lever are rotatably mated with support clasps that are engaged with and fixed to the end surfaces on both sides of the base.

9. The connector according to any one of claim 3, wherein

the rotary shafts of the control lever are rotatably mated with support clasps that are engaged with and fixed to the end surfaces on both sides of the base.

10. The connector according to any one of claim 4, wherein

the rotary shafts of the control lever are rotatably mated with support clasps that are engaged with and fixed to the end surfaces on both sides of the base.

11. The connector according to any one of claim 5, wherein

the rotary shafts of the control lever are rotatably mated with support clasps that are engaged with and fixed to the end surfaces on both sides of the base.

12. The connector according to any one of claim 6, wherein

the rotary shafts of the control lever are rotatably mated with support clasps that are engaged with and fixed to the end surfaces on both sides of the base.
