Abstract

The utility model relates to an Antenna feeder contact pin connector, which comprises a lining, a contact pin, an insulator, a shell, a snap ring, a first threaded sleeve, a second threaded sleeve, a rubber washer, and an upper and a lower sealing rings, wherein, the contact pin is inserted into the insulator; the insulator is arranged in the shell, and the peripheral surface of the insulator is closely matched with the inner wall of the shell; the lining is arranged in the shell and is contacted with the insulator; the lower sealing ring is positioned in a socket on the peripheral surface of the second threaded sleeve; the upper sealing ring is fixed in the second threaded sleeve and is connected to the back end of the shell; the snap ring is arranged at the front end of the shell; the first threaded sleeve is blocked and connected with the shell by the snap ring; an inner conical surface is arranged at the inner end of the second threaded sleeve; a conical surface is arranged at one end of the lining, wherein, the diameter of the conical surface is smaller than the inside diameter of the lining; the conical surface is closely matched with the inner conical surface; the connection of the structure is firm, thus reducing troubles in the installation.

Description

A kind of antenna feeder contact pin connector

Technical field

The utility model relates to a kind of mobile communication accessory, especially a kind of a kind of leading products that are used for connecting between the mobile communication equipment, specifically a kind of antenna feeder contact pin connector.

Background technology

At present, along with a large amount of construction of mobile communication, as the leading products that equipment connects, this coupling assembling consumption is very big, and easy for installation and fastness becomes the primary problem that solves of this product of improving.

Summary of the invention

The purpose of this utility model is at existing product problem inconvenient, that construction is difficult to be installed, and designs that a kind of contact pin exempts to weld, the connector of screw-type ply-yarn drill.

The technical solution of the utility model is:

A kind of antenna feeder contact pin connector, comprise lining, contact pin, insulator, shell, snap ring, first swivel nut, second swivel nut, rubber washer, on, lower seal, contact pin inserts in the insulator, insulator is located in the shell, its outer peripheral face and outer casing inner wall closely cooperate, lining is located in the shell and is contacted with insulator, lower seal is positioned at the groove on the second swivel nut outer peripheral face, last sealing ring is fixed in the rear end that is connected shell in second swivel nut, shell is provided with a snap ring, first swivel nut is by snap ring and shell clamping, establish a rubber washer on the shell, second swivel nut the inner is provided with an inner conical surface, and an end of institute's art lining is provided with a conical surface, its diameter is less than the internal diameter of lining, and the described conical surface and described inner conical surface closely cooperate.

A kind of antenna feeder contact pin connector, wherein, the inner peripheral surface of described second swivel nut inner peripheral surface and described sealing ring is respectively equipped with thread groove.

The utlity model has following advantage:

The utility model has improved cable assembly the problem difficult, that installation strength is not enough has been installed, general antenna feeder component all is to finish at the outdoor construction scene, conventional products all is to weld by the scene, pretty troublesome, overlap on line by the ply-yarn drill that adopts screw-type, just can go the line precession very like a cork, and it is firm, significantly reduced installer's trouble, by changing contact pin material, structure, by make a good contact pin uropore of elastic force with the material of beryllium-bronze, make the inner core of cable need not weld also and can be stuck on the contact pin firmly.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Embodiment

Following structure drawings and Examples are further described the utility model.

As shown in Figure 1.

A kind of antenna feeder contact pin connector, it is by lining 1, contact pin 2, insulator 3, shell 4, snap ring 5, first, two swivel nuts 6,7, rubber washer 8, lower seal 9, last sealing ring 10 is formed, the rear end of described contact pin 2 is provided with a uropore, the outer peripheral face of described uropore has some grooves, the material of contact pin 2 is a beryllium-bronze, contact pin 2 inserts in the insulator 3, insulator 3 is pressed in the shell 4, insulator 3 is pressed into and supports step in the shell 4, lining 1 is put into shell 4 and is supported insulator 3, last sealing ring 10 is put in the swivel nut 6 and with one and is pressed between second swivel nut, 6 inwalls and second swivel nut 6, thereby be fixed, sealing ring 9 is enclosed within the groove of swivel nut 6, I.S.S swivel nut 6 is spun in the shell 4, snap ring 5 is stuck on the shell 4, rubber washer 8 is placed on the shell 4, swivel nut 7 is compressed into snap ring, second swivel nut, 6 the inners are provided with an inner conical surface 61, one end of institute's art lining 1 is provided with a conical surface 11, its diameter is less than the internal diameter of lining 1, the described conical surface 11 closely cooperates with described inner conical surface 61, by precession second swivel nut 6, can make inner conical surface 61 compress the conical surface 11, thereby make lining 1 radial contraction, thereby clamping cables is installed for convenience, can be provided with thread groove at second swivel nut, 6 inner peripheral surfaces, the inner peripheral surface of described sealing ring 10 is provided with thread groove, sealing ring 10 is screw-type, and cable can directly pass through screw-type sealing ring 10, I.S.S swivel nut 6 precession products.

The utility model has adopted change contact pin material and structure, and construction is complicated, the problem of fastness difference thereby improved, and it is same as the prior art that the utility model does not relate to part.
