Abstract

The utility model relates to a double-strand wire rotary connector. A metal bearing is inlaid in an insulated outer shell; the outer cover of the metal bearing is fixed with the insulated outer shell; a strand of wires are connected through the inner cover and the outer cover of the metal bearing, and the other strand of wires are connected through conductors and a metal ball inlaid in the inner cover of the bearing; the conductors contacting with the metal ball are two cylindrical conductors with a concave spherical surface on one end; and under the action of a spring, the metal ball is extruded in the middle by the concave spherical surfaces of the two conductors. When the insulated outer shell rotates as power use equipment, through the sliding of the inner cover of the bearing and the conductors and the metal ball inlaid in the bearing, a lead connected with the equipment does not rotate together, thereby preventing the lead from being twisted into a ball and even being damaged because of the rotation of one end.

Description

The twinax cable swivel joint

Affiliated technical field:

The utility model relates to a kind of whirligig that twinax cable is rotated arbitrarily.

Background technology:

Twinax cable (as twisted-pair feeder) has a wide range of applications in routine work and life.Use the occasion of twinax cable at some, because the equipment rotation, and then rotation and strand be together even damage to cause a end that electric wire links to each other with equipment.

Summary of the invention:

Use the occasion of twinax cable owing to the rotation of electric wire one end causes electric wire strand problem together in order to solve at some, the utility model has designed a kind of twinax cable whirligig, when power consumption equipment rotates, by this whirligig, make the lead that links to each other with equipment and then not rotate, avoided bringing convenience to the user owing to the lead rotation is twisted into one even damage.

The technical scheme that its technical problem that solves the utility model adopts is: in insulation crust, a nested metal bearing, the overcoat of metal bearing is fixed, one electric wire connects by the inside and outside cover of metal bearing, another strand electric wire connects by conductor and the Metal Ball that is embedded in bearing inner sleeve, the conductor that contacts with Metal Ball is the cylindrical conductor that two one ends have concave spherical surface, and by the effect of spring, small metal ball is squeezed in the centre by two conductors.When insulation crust rotates along with power consumption equipment, by the slip of bearing inner sleeve, and be nested in the interior conductor of bearing and the slip of Metal Ball, make the lead that links to each other with equipment and then not rotate.Avoided owing to the rotation of lead one end is twisted into one even damage.

The beneficial effects of the utility model are: when power consumption equipment rotated, by this whirligig, the feasible lead that links to each other with equipment is and then rotation, had avoided bringing convenience to the user owing to the rotation of lead one end is twisted into one even damage.And this apparatus structure and technology are simple, convenient production.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a used unit generalized section of the present utility model.

Fig. 2 is a principle schematic of the present utility model.

Fig. 3 is the A--A cutaway view of Fig. 2.

Fig. 4 is the B--B cutaway view of Fig. 2.

Among Fig. 1: 1. lead 1,2. spring, 3. conductor 1 (end has the cylindrical conductor of concave spherical surface), 4. Metal Ball, 5. conductor 2 (end has the cylindrical conductor of concave spherical surface), 6. bearing, 7. insulating barrier, 8. lead 2,9. lead 3,10. insulating protection axle, 11. leads, 4,12. insulation crusts.

Embodiment:

In insulation crust, a nested metal bearing (6), the overcoat and the insulation crust of metal bearing are fixed together.

Lead 1 (1) bonding conductor 1 (3), conductor 1 are by Metal Ball (4) bonding conductor 2, and conductor 2 connects lead 2 (8).

Lead 3 (9) connects cover in the metal bearing, and lead 4 (11) connects the metal bearing overcoat, and metal bearing plays the effect of conductor simultaneously.

Conductor 2 is embedded in the interior cover of metal bearing by insulating barrier (7).

Spring (2) is connected with conductor 1.The effect of spring is to prevent owing to the small metal ball wearing and tearing cause loose contact.By the effect of spring, small metal ball is squeezed in the centre by conductor 1 and conductor 2.

Lead 8 and lead 9 pass insulating protection axle (10), and the insulating protection axle is used for fixing and guardwire 8 and lead 9.

Claims

1. twinax cable swivel joint, it is characterized in that: in insulation crust, a nested metal bearing, the overcoat and the insulation crust of metal bearing are fixed together, one electric wire connects by the inside and outside cover of metal bearing, and another strand electric wire connects by conductor and the Metal Ball that is embedded in bearing inner sleeve.
