Wiring structure improvement of insulation piercing connector
A wiring structure improvement of an insulation piercing connector for electrical connection after plural signal lines ( 40 ) being inserted includes a connector body ( 1 ), plural terminals ( 2 ) disposed in the connector body ( 1 ), and a rotary cable coupler ( 3 ). The connector body ( 1 ) has a wiring end ( 11 ). Each of the terminals ( 2 ) has a terminal body ( 20 ) and a piercing member ( 21 ) formed at one end of the terminal body ( 20 ) and disposed at the wiring end ( 11 ). The rotary cable coupler ( 3 ) is sleeved around the wiring end ( 11 ) and has plural plug holes ( 30 ) corresponding to the piercing members ( 21 ). Thus, when the rotary cable coupler ( 3 ) is rotated, the signal lines ( 40 ) are pushed by the plug holes ( 30 ) towards the piercing members ( 21 ) correspondingly such that the piercing members ( 21 ) pierce the signal lines ( 40 ) for the electrical connection.
1. A wiring structure improvement of an insulation piercing connector for electrical connection after a plurality of signal lines ( 40 ) being inserted, the wiring structure improvement comprising:
a connector body ( 1 ) having a connecting end ( 10 ) and a wiring end ( 11 );
a plurality of terminals ( 2 ) disposed in the connector body ( 1 ), wherein each of the terminals ( 2 ) has a terminal body ( 20 ) extending from the connecting end ( 10 ) to the wiring end ( 11 ) and a piercing member ( 21 ) formed at one end of the terminal body ( 20 ) and disposed at the wiring end ( 11 ); and
a rotary cable coupler ( 3 ) sleeved around the wiring end ( 11 ) and having a plurality of plug holes ( 30 ) corresponding to the piercing members ( 21 ) for insertion of the signal lines ( 40 ),
whereby when the rotary cable coupler ( 3 ) is rotated, the signal lines ( 40 ) are pushed by the plug holes ( 30 ) towards the piercing members ( 21 ) correspondingly such that the piercing members ( 21 ) pierce the signal lines ( 40 ) for the electrical connection.
2. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein the connecting end ( 10 ) and the wiring end ( 11 ) are disposed at two ends of the connector body ( 1 ), respectively.
3. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein a plurality of through-holes ( 110 ) are disposed at the wiring end ( 11 ) of the connector body ( 1 ), wherein the piercing member ( 21 ) of each of the terminals ( 2 ) is corresponding to one side of the respective through-hole ( 110 ).
4. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein the rotary cable coupler ( 3 ) has a cap-like shape.
5. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein the rotary cable coupler ( 3 ) is provided with a line fastener ( 31 ) having a plurality of fixing holes ( 310 ) corresponding to the respective plug holes ( 30 ).
6. The wiring structure improvement of the insulation piercing connector according to claim 5 , wherein each of the fixing holes ( 310 ) is formed and surrounded by two hook portions ( 311 ) oppositely spaced on the line fastener ( 31 ), wherein an embedded slot ( 312 ) is formed between the two hook portions ( 311 ).
7. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein each of the plug holes ( 30 ) has decreasing diameters, wherein a pressing surface ( 300 ) is disposed on an inner edge of each plug hole ( 30 ), which is located at an end with the largest diameter.
8. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein the piercing members ( 21 ) are disposed on a side surface of the wiring end ( 11 ).
9. The wiring structure improvement of the insulation piercing connector according to claim 8 , wherein the piercing members ( 21 ) are arranged circularly.
10. The wiring structure improvement of the insulation piercing connector according to claim 1 , wherein each of the piercing members ( 21 ) has two spaced apart piercing blades ( 210 ), wherein a slot ( 211 ) is formed between the two piercing blades ( 210 ).
11. The wiring structure improvement of the insulation piercing connector according to claim 10 , wherein the slot ( 211 ) of each piercing member ( 21 ) has a “Y” shape.
12. The wiring structure improvement of the insulation piercing connector according to claim 10 , wherein the slot ( 211 ) of each piercing member ( 21 ) is arranged to have a direction opposite to that of the rotation of the rotary cable coupler ( 3 ) to pierce the signal lines ( 40 ).
