Abstract

The utility model provides a multi-core plug capable of fixing cable and dustproof, relating to the technical field of cable plugging device. The splicing sleeve inner cavity is provided with a plurality of guide grooves, and a plug sleeve, a claw sleeve, a sheath are inserted in the splicing sleeve inner cavity in sequence. The wire protecting sleeve is arranged in the inner cavity of the elastic claw of the claw sleeve. A nut B is screw connected with the splicing sleeve, the nut B is tightened to cause the sheath to generate axial displacement and force the elastic claw of the claw sleeve and the wire protecting sleeve to carry out radial contraction, realizing clamping and fixing cable and making the wire connection inner cavity dustproof. The metal hose is connected with the end of the nut B by a nut A, a rubber sleeve, a liner or an earthing strip and is caused to contact the earth.

Description

Multi-core plug cabable of fixing cable and dustproof

The utility model relates to cable grafting device technical field.

Existing multi-pin connector fixed cable makes pressing plate clamp cable by tightening two screws.There is and use inconveniently, can not airtightly prevent dust, can not connect thread-protected tube, appearance and modeling is poor, and defective such as make trouble.

The purpose of this utility model provides a kind of cable that can be fixedly clamped reliably, can airtightly prevent dust again, can also connect thread-protected tube, and good looking appearance uses again multi-pin connector very easily.

The purpose of this utility model is achieved in that and only is provided with in connecing cover and can makes axially movable sheath and catch jacket along connecing the cover gathering sill.Sheath is placed in outside the elastic card claw of catch jacket.Can only place wire bushing A according to the diameter decision of clamped fixed cable again in the elastic card claw of catch jacket, or place wire bushing B again.Nut B is threaded with connecing to apply mechanically.When fastening nut B, sheath is promptly done axial displacement thereupon.Under the effect of sheath internal taper hole, the elastic card claw of catch jacket just dwindles the aperture of wire bushing, thereby the chucking of the cable in the wire bushing is fixing.So just make not stand under load of cable ends, to avoid under states such as tension or vibration, making cable ends and wiring pile crown phenomenon occur disconnecting.And can also work to prevent that dust from entering multi-pin connector wiring inner chamber.Owing to be provided with sheath, the spin friction power that is produced during fastening nut B just can not affact on the elastic card claw again.So just can when fastening nut B, avoid elastic card claw to produce the rotation distortion.

The utility model compared with prior art has the cable that can be fixedly clamped easily and reliably, and is can be airtight dustproof, can connect metal hose, and can realize the interior ground connection of metal hose and prevent that metal hose from being drawn diffusing, good looking appearance, advantage such as easy to manufacture.

Below in conjunction with the embodiment shown in the accompanying drawing 1 the utility model is further described.

Accompanying drawing 1 is the multi-pin connector installation diagram of loading onto behind the metal hose.

The mark sequence number is expressed as follows respectively in the accompanying drawing 1: 1. nut A 2. rubber sleeves 3. linings 4. ground strips 5. metal hoses 6. nut B 7. sheaths 8. wire bushing A 9. wire bushing B 10. catch jackets 11. connect cover 12. sleeves 13. nut C 14. bases 15. lock pins 16. back-up rings

From accompanying drawing 1 as can be seen, connect cover (11) inner chamber several gathering sills are arranged.Sleeve (12), catch jacket (10), sheath (7) all are that benchmark inserts successively at the inner chamber that connects cover (11) with the gathering sill.Wire bushing A(8), wire bushing B(9) be positioned over the inner chamber of catch jacket (10) elastic card claw.Sheath (7) is placed in outside catch jacket (10) elastic card claw.Nut B(6) with connect cover (11) with being threaded.Fastening nut B(6) after, the axial location of sleeve (12), catch jacket (10), sheath (7) promptly is fixed.The elastic card claw of catch jacket (10) dwindles the aperture of wire bushing under the effect of sheath (7) internal taper hole, thereby the chucking of the cable in the wire bushing is fixing.Only need turn on nut B(6 during wiring), just can take out sheath (7), catch jacket (10), sleeve (12) successively, carry out wiring easily.Lock pin (15) inserts in the inner chamber of base (14), and carries out axial location with back-up ring (16).Behind the plug insertion socket, but fastening nut C(13) plug and socket are linked into an integrated entity.

As adopting the thread-protected tube of metal hose as cable in the electrical engineering, the available lining (3) that has outer convex thread is screwed into the inner spiral groove of metal hose end.Rubber sleeve (2) is enclosed within the outside of metal hose.Use nut A(1) with nut B(6) screw, metal hose just is connected nut B(6 reliably) the end.Because clamped fixing cable can be placed restrictions on the tension elongation of metal hose, just make metal hose be difficult for producing and drawn the phenomenon of loosing and taking off head.Can place a slice ground strip (4) at the top of lining (3).With lead ground strip (4) is connected with the Earth pile-head of multi-pin connector, just can realizes the interior ground connection of metal hose.

As only requiring to be fixedly clamped cable and make wire connection cavity dustproof in the electrical engineering.Only need to remove nut A(1), rubber sleeve (2), lining (3), ground strip (4) and nut B(6) end has externally threaded part, just can become a kind of only be fixedly clamped cable with make wire connection cavity dustproof multi-pin connector.

Claims

1, a kind of energy fixed cable and dustproof multi-pin connector are by nut A (1); Rubber sleeve (2); Lining (3); Ground strip (4); Nut B (6); Sheath (7); Wire bushing A (8); Wire bushing B (9); Catch jacket (10); Connect cover (11); Sleeve (12); Nut C (13); Base (14); Lock pin (15); Back-up ring (16) is formed, it is characterized in that connecing and only be provided with in the cover (11) and can make axially movable sleeve (12), catch jacket (10), sheath (7) along connecing cover (11) gathering sill, sheath (7) is placed in outside the elastic card claw of catch jacket (10), can only place wire bushing A (8) according to the diameter decision of clamped fixed cable again in the elastic card claw of catch jacket (10), or place wire bushing B (9) again, nut B (6) with connect cover (11) with being threaded.
