Abstract

The utility model provides a kind of straight wire pin, comprise tailstock, inner wire socket, screen joint, aluminium hydraulic pressed connecting pipe, outer conductor contact head, inner wire contact pin, described screen joint and outer conductor joint are arranged on tailstock two ends respectively, and for conduction connects between three; Described inner wire socket and inner wire contact pin are arranged in screen joint and outer conductor contact head respectively, and conduct electricity connection between the two; Described inner wire socket and inner wire contact pin and screen joint, to insulate between outer conductor joint and tailstock; Described aluminium hydraulic pressed connecting pipe is sleeved on outside screen joint.Of the present utility modelly in use aluminium hydraulic pressed connecting pipe is sleeved on screen and screen weld position, in use because aluminium hydraulic pressed connecting pipe effectively can be suppressed welding position, avoid the problem of sealing-off between screen and screen joint, substantially increase the useful life of straight wire pin.

Description

Straight wire pin

Technical field

The utility model relates to a kind of straight wire pin.

Background technology

This L9 (1.6/5.6) straight wire pin is widely used in the fields such as post and telecommunications, microwave communication, microwave measuring equipment.Product is straight plug, and product rear end connects coaxial cable.Existing straight wire pin, directly the inner wire of cable is welded in inner wire socket, and screen is welded on outside screen joint, this connected mode, because wire pin in use often produces relative rocking with cable plug, therefore its interior welds, welds the problem that may produce sealing-off especially between screen with screen joint, thus cause loose contact, cause connection to go wrong.

Utility model content

The technical problems to be solved in the utility model is: overcome the problem of welding between screen with screen joint in prior art and in use easily producing sealing-off, provides a kind of straight wire pin.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of straight wire pin, comprise tailstock, inner wire socket, screen joint, aluminium hydraulic pressed connecting pipe, outer conductor contact head, inner wire contact pin, described screen joint and outer conductor joint are arranged on tailstock two ends respectively, and for conduction connects between three; Described inner wire socket and inner wire contact pin are arranged in screen joint and outer conductor contact head respectively, and conduct electricity connection between the two; Described inner wire socket and inner wire contact pin and screen joint, to insulate between outer conductor joint and tailstock; Described aluminium hydraulic pressed connecting pipe is sleeved on outside screen joint.

Further, the inner wire due to cable needs to be welded on inner wire socket, for the ease of welding, described screen joint side offers soldering opening

Further, outside described outer conductor contact head, be socketed with swivel nut, connect can not produce slip phenomenon by swivel nut external equipment.

Further, in described outer conductor contact head and tailstock, be filled with insulator, avoid external contact and tailstock and internal wiring short circuit.

For being effectively connected with cable, as preferably, outside described screen joint, be threaded connection shell.

As preferably, described screen joint and tailstock are integrated, and are threaded connection between described outer conductor contact head and tailstock.

The beneficial effects of the utility model are, of the present utility modelly in use aluminium hydraulic pressed connecting pipe is sleeved on screen and screen weld position, in use because aluminium hydraulic pressed connecting pipe effectively can be suppressed welding position, avoid the problem of sealing-off between screen and screen joint, substantially increase the useful life of straight wire pin.

1. tailstocks in figure, 2. inner wire socket, 3. screen joint, 31. soldering openings, 4. aluminium hydraulic pressed connecting pipe, 5. outer conductor contact head, 6. inner wire contact pin, 7. swivel nut, 8. insulator, 9. shell, 10. heart yearn, 11. screens.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

Embodiment 1

As shown in Figure 1, a kind of straight wire pin comprises tailstock 1, inner wire socket 2, screen joint 3, aluminium hydraulic pressed connecting pipe 4, outer conductor contact head 5, inner wire contact pin 6, described screen joint 3 and outer conductor joint are arranged on tailstock 1 two ends respectively, and be respectively aluminium, aluminium and brass for conduction connects tailstock 1, screen joint 3 and outer conductor joint material between three, in the present embodiment, screen joint 3 and tailstock 1 are integrated, and are threaded connection between described outer conductor contact head 5 and tailstock 1; Described inner wire socket 2 and inner wire contact pin 6 are arranged in screen joint 3 and outer conductor contact head 5 respectively, and the inner wire of conduction connection between the two socket 2 and inner wire contact pin 6 material are brass; Be filled with insulator 8 in described outer conductor contact head 5 and tailstock 1, avoid external contact and tailstock 1 and internal wiring short circuit; Described aluminium hydraulic pressed connecting pipe 4 is sleeved on outside screen joint 3.Inner wire due to cable needs to be welded on inner wire socket 2, for the ease of welding, described screen joint 3 side also offers soldering opening 31.Swivel nut 7 is socketed with outside described outer conductor contact head 5; Shell 9 has been threaded connection outside described screen joint 3.

In use, first back out shell 9, shell 9 is enclosed within the cable stripped, then the heart yearn 10 of cable is inserted in inner wire socket 2 through screen joint 3, ensure the insulating barrier of now cable and screen joint 3 contact internal walls (avoiding heart yearn 10 to contact with screen joint 3), then the screen 11 of cable is stripped in the hole between screen 11 contact head and aluminium hydraulic pressed connecting pipe 4, then heart yearn 10 is welded in inner wire socket 2, screen 11 is welded between screen joint 3 and aluminium hydraulic pressed connecting pipe 4, then to screw on shell 9, namely the connection of plug and cable is completed, this kind of connected mode is solid and reliable, effectively improve its useful life.
