Abstract
The utility model belongs to a pin-shaped electric connector, particularly a connector for connecting flexible cables, which is composed of an outer conductor and a locking nut. The utility model is characterized in that an outer cone sleeve is arranged behind outer screw threads of the outer conductor, an inner cone sleeve is arranged behind the locking nut, an annular slot is formed between the inner wall of the inner cone sleeve and the conical face of the outer cone sleeve. A cable core and an insulation layer of a cable is arranged in a through hole of the outer conductor, the naked cable core extending to the front end of the outer conductor is a contact pin, a shielding layer and a protecting sleeve are inserted in the annular slot and are pressed by the locking nut when the locking nut is screwed in the outer conductor, and the cable is fixed on the connector. The utility model has the advantages of excellent impedance matching, simple structure, simple connection and high electrical property and mechanical reliability.
Description
The utility model relates to flexible cable and rack (case, trunk line station, finger assignments, printed board etc.) direct connector in the compatible systems such as a kind of pin type electric connector, particularly common antenna, cable TV, satellite communication.
Now be used for compatible system flexible cable such as common antenna, cable TV, satellite communication and rack (case, trunk line station, finger assignments, printed board etc.) and peg graft and be generally male connector, " the EI500K type divides hole connector " of producing as the inferior company of flood.Its structure as shown in Figure 1, mainly comprise the externally threaded outer conductor 6 of rear end band, tapped locking nut 4, be fixed on the contact pin 3 before the outer conductor 6 on outer conductor 6 axle center, contact pin 3 partly has the jack that inserts cable core at outer conductor 6 through holes, tapered sleeve 7 and the sleeve 5 fixed by the bolt 2 that matches with outer conductor 6 are arranged in the outer conductor 6, form an annular slot between tapered sleeve 7 and the sleeve 5, other 8 is the positioning adapter of contact pin 3,9 is the positioning adapter of tapered sleeve 7 and sleeve 5, and 1 is that packing ring, 11 is that sealing ring, 12 is that sealing ring, 13 is sealing ring.The process of its stube cable is: cable is a flexible cable, is made of cable core, insulating barrier, shielding layer and outer protective sleeve.With specific purpose tool cable core is inserted in the jack of contact pin 3 in outer conductor 6 through holes during connection, between the contact pin 3 of insulating barrier in tapered sleeve 7 and outer conductor 6, sheath and shielding layer insert in the annular slot, will go into outer conductor 6 on the locking nut 4 then.Because the outer wall of tapered sleeve 7 has a tapering, so annular slot is that import is bigger, the inside reduces gradually, therefore, bolt 2 will promote sheath when being tightened in the outer conductor 6 and shielding layer is got into to less space, and compression sleeve 5 clamping sheath and shielding layers, thereby cable is fastened on the connector.The shortcoming of this connector is: because cable core is to insert in the jack of contact pin 3 to be communicated with, so its impedance matching is relatively poor; Cable is connected with connector needs specific purpose tool, connects complicated; This connector construction complexity makes that electrical property and Mechanical Reliability are relatively poor.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of cable core direct for contact pin, simple in structure, easy to connect, the flexible cable direct connector that electrical property and Mechanical Reliability are higher.
Solution of the present utility model is: the flexible cable direct connector is made of outer conductor and locking nut, external screw thread is arranged on the outer conductor, the locking nut front end has the internal thread that matches with the external screw thread of outer conductor, it in the outer conductor through hole, the external screw thread rear end that is characterized in outer conductor is an external conical sleeve, the internal thread rear end of locking nut is an inner conical drogue, forms an annular slot between the inwall of inner conical drogue and the conical surface of external conical sleeve.The principle of the utility model stube cable is: in advance insulating barrier, shielding layer and the sheath of one section of flexible cable termination pruned, made the cable socket cable core exposed, and one section prune shielding layer and sheath behind the exposed cable core, the back is complete cable again.Locking nut is inserted in the cable, then the external conical sleeve end of cable socket from outer conductor inserted inwards, the cable core of cable and insulating barrier are inserted in the through hole of outer conductor, exposed cable core exposes from the outer conductor front end, the shielding layer of cable and sheath partly insert in the cannelure, at last locking nut are screwed on the outer conductor.The precession of locking nut, sheath and the shielding layer of extruding in the annular slot is fastening with it, finish cable and be fixed on the connector.The connector that fixes cable can directly insert rack.
In the solution of the present utility model when annular slot reaches the external screw thread inner lane of outer conductor, the locking nut precession, to push sheath and shielding layer advances in annular slot, make sheath and the shielding layer front end annular slot lowermost end that walks, and extruding sheath and shielding layer tighten up it, and what cable was stable like this is fixed on the connector.When cutting cable in advance, sheath is pruned slightly more than shielding layer, a sheath and a worn-out screen layer front end walk behind the annular slot lowermost end, continue to screw locking nut, and the shielding layer reflex action that can make the sheath front end is between outer conductor and inner conical drogue, and is fixing more stable.
When the cone angle of external conical sleeve was 3 °～10 ° in the solution of the present utility model, sheath and shielding layer inserted annular slot and are easier to, and cable is fixing also more stable.
The utility model advantage compared with prior art: because the utility model structure can make contact pin is the cable core of cable, so impedance matching is fabulous, cable is connected with connector simply, reliable and stable, need not special fastening means, connector construction is simple, and cost is low.
The utility model can further specify in conjunction with the accompanying drawings.
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model embodiment half sectional view
The utility model embodiment as shown in Figure 2, the flexible cable direct connector is by outer conductor 6, locking nut 4 constitutes, there is the anterior external screw thread that is connected on the rack outer conductor 6 front portions, there is the external screw thread that matches with the internal thread of locking nut 4 at outer conductor 6 middle parts, behind the middle part external screw thread of outer conductor 6 external conical sleeve 14 is arranged, external conical sleeve 14 is connected as a single entity with outer conductor 6, the conical surface of external conical sleeve 14 protrudes in the external screw thread inner lane of outer conductor 6, one inner conical drogue 15 is arranged behind the internal thread of locking nut 4, form an annular slot between the conical surface of the inwall of inner conical drogue 15 and external conical sleeve 14, be embedded with a sealing ring 12 behind the front end external screw thread of outer conductor 6, be embedded with a sealing ring 13 on the external screw thread in the middle of the outer conductor 6, be embedded with a sealing ring 16 on the inwall of inner conical drogue 15.17 is cable, and cable 17 is by cable core 18, insulating barrier 19, and sheath and shielding layer 20 constitute.When being fixed on cable 17 on the connector, the termination of cable core 18 reaches the front end of outer conductor 6, and insulating barrier 19 is in outer conductor 6 through holes, and sheath and shielding layer 20 insert in the annular slot, inner conical drogue 15 extruding of nut 4 of being locked tightens up, and cable 17 is fixed on the connector.The connector that connects cable 17 can be connected on the rack by outer conductor 6 anterior external screw threads, and the cable core 18 of outer conductor 6 bare front end is plugged on the binding post of rack.
