Abstract
The utility model discloses a pin connector, which comprises a pin (1), insulators (2, 3), an external conductor (4), a snap ring (5), a tight connecting sleeve (6), threaded sleeves (7, 8) and a sealing ring (9). The pin (1) is tightly installed in the inner hole of the insulator (2); the threaded sleeve (7) is fastened with the external conductor (4) by means of the snap ring (5); and the threaded sleeve (8) is screwed in one end of the external conductor (4); the insulator (3) is tightly installed in the threaded sleeve (8); one end of the insulator (3) abuts against the first sunken bottom (81) of the threaded sleeve (8), and the other end abuts against the positioning step (41) of the inner hole of the external conductor (4); the first end of the insulator (3) is clamped in the second sunken hole (82) of the threaded sleeve (8), and the second end of the insulator (3) is clamped in the sunken step (21) of the insulator (2). An annular step (11) which is extended along a radial direction on the flat end of the pin (1) matches an annular groove formed by the insulators (2, 3), and the structure axially positions the pin (1). When the pin connector is used, the pin (1) cannot be drawn out of the threaded sleeve (8), thus fundamentally preventing a cable from falling off a terminal.
Description
Technical field
The utility model relates to a kind of communications cable accessory, and especially a kind of connector that is used for communications cable connection belongs to the communication equipment technical field.
Background technology
As everyone knows, in communications industry,, need to use contact pin connector in order to guarantee the firm connection of cable.And the standing part of existing contact pin connector adopts the afterbody crimping usually, this structure only depends on the screen of cable appearance and is connected, and clamping force is limited, when work often because the effect of extraneous power, cable and joint are come off, influence its normal service behaviour.
Summary of the invention
The purpose of this utility model is at existing cable and the caducous problem of joint, designs a kind of contact pin connector of split-type structural, makes cable and joint firm.
The technical solution of the utility model is: a kind of contact pin connector, comprise contact pin 1, insulator 2,3, outer conductor 4, snap ring 5, pressure welding case 6, swivel nut 7,8, sealing ring 9, described contact pin 1 is fitted in the endoporus of insulator 2, described swivel nut 7 is by snap ring 5 and outer conductor 4 clampings, and described swivel nut 8 spinnings are in outer conductor 4 one ends; Described insulator 3 is fitted in the swivel nut 8, and the one end is resisted against on the first counterbore bottom surface 81 of swivel nut 8, and the other end is resisted against on the positioning step 41 of outer conductor 4 endoporus; First end of described insulator 3 is installed in second counterbore 82 of swivel nut 8, and second end of this insulator 3 is installed in the sinking step 21 of insulator 2.
The ring-shaped step 11 that the flush end of contact pin 1 radially extends is complementary with the cannelure that insulator 2, insulator 3 constitute.
Sealing ring 9 is sleeved on the neck of outer conductor 4, between the endoporus of the outer peripheral face of outer conductor 4 necks and swivel nut 7,
The utility model has fundamentally prevented the phenomenon that cable and joint come off, and simultaneously also can make the installation of line more firm, safer.The utility model is made into two insulators 2,3 that independently, mate with each other to an original insulator, an original outer conductor also is made into two outer conductor 4 and swivel nuts 8 by being threaded, and the cannelure that ring-shaped step that the flush end of contact pin 1 radially extends and insulator 2, insulator 3 constitute is complementary.The restriction that axially is subjected to insulator 2,3 and outer conductor 4 and swivel nut 8 of contact pin 1 and can not going here and there can guarantee that contact pin 1 can not pull out from swivel nut 8.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.As shown in Figure 1, a kind of contact pin connector of the present utility model, it comprises contact pin 1, insulator 2,3, outer conductor 4, snap ring 5, pressure welding case 6, swivel nut 7,8, sealing ring 9, contact pin 1 is fitted in the endoporus of insulator 2, swivel nut 7 is by snap ring 5 and outer conductor 4 clampings, and swivel nut 8 spinnings are in outer conductor 4 one ends; Insulator 3 is fitted in the swivel nut 8, and the one end is resisted against on the first counterbore bottom surface 81 of swivel nut 8, and the other end is resisted against on the positioning step 41 of outer conductor 4 endoporus; First end of insulator 3 is installed in second counterbore 82 of swivel nut 8, and second end of this insulator 3 is installed in the sinking step 21 of insulator 2.
The ring-shaped step 11 that the flush end of contact pin 1 radially extends is complementary with the cannelure that insulator 2, insulator 3 constitute, and makes contact pin 1 axial location, can not pull out from swivel nut 8.Sealing ring 9 is sleeved on the neck of outer conductor 4, between the endoporus of the outer peripheral face of outer conductor 4 necks and swivel nut 7.When the utility model is connected with external equipment, because the sealing function of sealing ring 9 has prevented outside aqueous vapor access arrangement.
In addition to the implementation, the present invention can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
Claims (3)
