an insulation layer on a portion of the contact main body located between the contact main body and the contacting member, the contact main body contacting with the contacting member.
2. The contact according to claim 1 , wherein the wire fixing portion is arranged on a back side of the base portion.
3. The contact according to claim 2 , wherein a core wire of the wire is on the extension portion and is connected to the extension portion by the wire fixing portion.
4. The contact according to claim 3 , wherein the insulation layer is also on a portion of the wire fixing portion contacting the core wire of the wire in addition to the portion of the contact main body contacting with the contacting member.
5. The contact according to claim 4 , wherein the core wire of the wire and the contacting member are made of a metal material of the same kind and the contact main body and the contacting member are made of metal materials of different kinds.
6. The contact according to claim 5 , wherein the core wire of the wire and the contacting member are made of metal materials for a thermocouple.
7. The contact according to claim 6 , wherein the contacting member has a tab-like contact portion extending forward from the fixing portion for contacting with the mating contact.
8. The contact according to claim 6 , wherein the contacting member fixing portion has an approximately box-like shape for receiving the mating contact and has an elastic contacting piece extending from an upper wall of the contacting member fixing portion toward the fixing portion of the contacting member.
9. The contact according to claim 8 , wherein the mating contact is received between the fixing portion and the elastic contacting piece to contact with the fixing portion.
10. The contact according to claim 9 , wherein the wire fixing portion has a crimping portion for crimping the wire.
11. The contact according to claim 9 , wherein the wire fixing portion has a spring clamp.
12. A contact comprising:
a contact main body having:
a wire fixing portion configured to be fixed with a wire; and
a base portion; and
a contacting member fixing portion for fixing a contacting member arranged on a front side of the base portion; and
the contacting member is formed separately from the contact main body and is configured to be connected to the wire and contact with a mating contact, wherein the contacting member comprises:
a fixing portion fixed to the contacting member fixing portion; and
an extension portion extending backward from the fixing portion up to the wire fixing portion, wherein a core wire of the wire is on the extension portion and is connected to the extension portion by the wire fixing portion, and wherein an insulation layer is on a portion of the wire fixing portion contacting the core wire of the wire in addition to the portion of the contact main body contacting with the contacting member.
13. The contact according to claim 12 , wherein the core wire of the wire and the contacting member are made of a metal material of the same kind and the contact main body and the contacting member are made of metal materials of different kinds.
14. The contact according to claim 13 , wherein the core wire of the wire and the contacting member are made of metal materials for a thermocouple.
15. The contact according to claim 14 , wherein the contacting member has a tab-like contact portion extending forward from the fixing portion for contacting with the mating contact.
16. The contact according to claim 14 , wherein the contacting member fixing portion has an approximately box-like shape for receiving the mating contact and has an elastic contacting piece extending from an upper wall of the contacting member fixing portion toward the fixing portion of the contacting member.
17. The contact according to claim 16 , wherein the mating contact is received between the fixing portion and the elastic contacting piece to contact with the fixing portion.
18. The contact according to claim 17 , wherein the wire fixing portion has a crimping portion for crimping the wire.
