Connector

1. A connector, the connector comprising:

a metal fitting in which a through-hole is formed; and

a case, the case comprising:

a support groove for containing the metal fitting in such a manner as to restrict the displacement of the metal fitting at least in the extending direction of the through-hole, and

an insertion hole for inserting a cable, the insertion hole being continuous to the support groove in such a manner that the cable inserted into the insertion hole is inserted into the through-hole of the metal fitting contained in the support groove;

wherein the metal fitting contained in the support groove plastically deforms such that the size of the through-hole decreases when it is compressed in the depth direction of the support groove.

2. The connector according to claim 1 , wherein the metal fitting comprises a compression part, the compression part protruding in the direction away from the through-hole, which is the direction opposite to the depth direction of the support groove.

3. The connector according to claim 2 , wherein the compression part comprises an incision tooth part, the incision tooth part formed such that the edge of the through-hole protrudes in the depth direction of the support groove to come into contact with the cable.

4. The connector according to claim 3 , wherein a receiving part is formed at a portion facing the incisor tooth part on the edge of the through-hole, the receiving part having a curved shape along the outward form of the cable.

5. The connector according to claim 4 , wherein the metal fitting comprises protrusions on both sides of the compression part in the width direction of the support groove, the protrusions protruding in the direction opposite to the depth direction of the support groove.

6. The connector according to claim 5 , wherein the metal fitting is a terminal composed of bent metal plates and comprises a first plate part comprising the compression part and on which the through-hole is formed and a second plate part comprising a contact part for contacting the other terminal and on which the through-hole is formed, wherein the first plate part and the second plate part overlaps each other in such a manner that the through-holes become continuous.

7. The connector according to claim 1 , wherein the metal filling is a metal fitting that comes into contact with the insulating outer coat of the cable.

8. The connector according to claim 1 , wherein the compression part comprises an incision tooth part formed in such a manner that the edge of the through-hole protrudes in the depth direction of the support groove, wherein the incisor tooth part cuts the insulating outer coat of the cable and comes into contact with metal wires inside when the compression part is compressed in the depth direction of the support groove.

9. A connector, the connector comprising:

a first metal fitting on which a through-hole is formed;

a second metal fitting on which a through-hole is formed; and

a case, the case comprising:

a first support groove for containing the first metal fitting in such a manner as to restrict the displacement of the first metal fitting at least in the extending direction of the through-hole;

a second support groove for containing the second metal fitting in such a manner as to restrict the displacement of the second metal fitting at least in the extending direction of the through-hole; and

an insertion hole for inserting a cable, the insertion hole being continuous to the first support groove and the second support groove in such a manner that the cable inserted into the insertion hole is sequentially inserted into the through-hole of the first metal filling contained in the first support groove and the through-hole of the second metal filling contained in the second support groove;

wherein:

the first metal fitting contained in the first support groove plastically deforms such that the size of the through-hole decreases when it is compressed in the depth direction of the first support groove and comes into contact with the insulating outer coat of the cable; and

the second metal fitting contained in the second support groove plastically deforms such that the size of the through-hole decreases when it is compressed in the depth direction of the second support groove and comes into contact with metal wires exposed at the tip end of the cable.

10. The connector according to claim 9 , wherein:

the cable is a coaxial cable;

the connector further comprises a third metal fitting on which a through-hole is formed; and

the case further comprises a third support groove for containing the third metal fitting, the third support groove being disposed between the first support groove and the second support groove, being continuous to the insertion hole and restricting the displacement of the third metal fitting at least in the extending direction of the through-hole;

wherein the third metal fitting contained in the third support groove plastically deforms such that the size of the through-hole decreases when it is compressed in the depth direction of the third support groove and comes into contact with an outer conductor exposed between metal wires exposed at the tip end of the coaxial cable and the insulating outer coat.
