Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 2 and 3, for the utility model discloses a multicore connector, including public head 1 and female head 2, public head 1 serves to be equipped with a plurality of contact pins 11 and two reference columns 12 along its length direction, and female head 2's one end is equipped with a plurality of jacks 21 with contact pin 11 adaptation and two locating holes 22 with reference column 12 adaptation along its length direction. Two reference column 12 and two locating hole 22 interference fit have greatly promoted the steadiness of public first 1 and female first 2 grafting, appear not hard up phenomenon after avoiding public first 1 and female first 2 to peg graft, can avoid the dust to pass through in the gap gets into locating hole 22 simultaneously. Two reference columns 12 are located the both ends along length direction of public first 1 terminal surface respectively, and a plurality of contact pins 11 are located between two reference columns 12 on public first 1, and female 2 is gone up the terminal surface that jack 21 place and is grafting surface 28, and grafting surface 28 middle part is upwards tensile and is formed boss 25, and jack 21 is located boss 25, and the boss 25 that jack 21 place and the structure of the type of the convex letter that the platform that two locating holes 22 were located formed. The length of two positioning columns 12 is greater than the sum of the length of pin 11 and the height of boss 25, so that before pin 11 is inserted into socket 21, positioning columns 12 are inserted into positioning holes 22 first, and alignment between pin 11 and socket 21 is facilitated. When public first 1 and female first 2 are pegged graft together, location column 12 on public first 1 inserts in the locating hole 22 on the female first 2, public first 1 goes up contact pin 11 and inserts in the jack 21 on the boss 25, because jack 21 is located the boss 25, make contact pin 11 and jack 21 can neatly peg graft, and the up end of two locating holes 22 on the female first 2 does not contact with public first 1, can not receive the dust influence and the phenomenon that the high one end of one end is low appears when leading to public first 1 and female first 2 to peg graft, avoid appearing because public first 1 female first 2 can't peg graft neatly and lead to the great phenomenon of optical fiber transmission loss.

Referring to fig. 2 and 4, the insertion surface 28 is recessed downwards along the circumferential direction to form an annular groove 23, the end face of one end where the pin 11 is located on the male connector 1 is stretched upwards to form an annular protrusion 13 in insertion fit with the annular groove, the annular groove 23 and the annular protrusion 13 are in insertion fit to enable the male connector 1 and the female connector 2 to be inserted tightly, the pin 11 and the positioning column 12 are sealed by the annular protrusion 13 in the insertion use process, and external dust can be effectively prevented from entering the insertion hole 21 and the positioning hole 22 to influence the use of the multi-core connector. Meanwhile, the annular protrusion 13 can also protect the pin 11 and the positioning column 12, so that the pin 11 and the positioning column 12 are prevented from being broken and bent due to external influence. The outer side wall of the annular protrusion 13 is provided with an annular locking protrusion 14 with a semicircular section along the circumferential direction, and the inner side wall of the annular groove 23 is provided with a locking groove 24 matched with the annular locking protrusion 14. When public first 1 is pegged graft with female first 2, inside inserting jack 21 when contact pin 11 is located completely, annular locking protrusion 14 just inlay in locking groove 24 this moment, locks annular protrusion 13, has greatly promoted the steadiness that public first 1 and female first 2 were pegged graft, appears not hard up phenomenon and then leads to the great phenomenon of optical fiber transmission loss after avoiding public first 1 and female first 2 to peg graft.

Referring to fig. 2 and 3, public first 1 and female 2 outside all covers and is equipped with the protective housing 15 that mutually supports the butt and form the enclosure space, can effectually protect public first 1 and female 2, reduces the harm of external factors to public first 1 and female 2. Rubber pad 27 has all been laid to the butt department on the protective housing 15 of public first 1 and the protective housing 15 of female head 2, and after public first 1 and female head 2 pegged graft, the protective housing 15 butt cooperation of its outside forms the enclosure space, and the rubber pad 27 of butt department has elasticity, can be so that public first 1 and the more inseparable of protective housing 15 butt on the female head 2 in, can effectively prevent that external dust from getting into and influencing the use of multicore connector in jack 21 and the locating hole 22. Be equipped with locking post 16 on the lateral wall of male head 1's protective housing 15, rotate on female head 2's protective housing 15's the lateral wall be connected with locking post 16 buckle complex locking hook 26, locking post 16 and locking lever all are equipped with two in this embodiment, can rotate locking hook 26 after male head 1 and female head 2 are pegged graft and are accomplished and detain on locking post 16, lock male head 1 and female head 2 after pegging graft, the not hard up phenomenon appears after avoiding male head 1 and female head 2 to peg graft, ensure optical fiber transmission's stability.

The implementation principle of the embodiment is as follows: when public first 1 and female first 2 peg graft, reference column 12 inserts at first in the locating hole 22, then along with the insertion of reference column 12, in public first 1 goes up contact pin 11 is being guided and is inserting the jack 21 on the 2 boss 25 of female first, because jack 21 is located the boss 25 for contact pin 11 and jack 21 can neatly peg graft, and two locating hole 22's on the female first 2 up end do not contact with public first 1, can not receive the dust influence and appear the phenomenon that one end is high when leading to public first 1 and female first 2 to peg graft. Simultaneously annular protrusion 13 inserts annular groove 23 on female head 2 on male head 1 inside, inside inserting jack 21 when contact pin 11 is located completely, annular locking protrusion 14 just inlay in locking groove 24 this moment, locks annular protrusion 13, has greatly promoted the steadiness of male head 1 with female head 2 grafting, appears not hard up phenomenon and then leads to the great phenomenon of optical fiber transmission loss after avoiding male head 1 and female head 2 to peg graft. Public first 1 and the outside protective housing 15 butt of female head 2 this moment form the enclosure space, protect public first 1 and female head 2, reduce the harm of external factor to public first 1 and female head 2. The rotary locking hook 26 is buckled on the locking column 16 to lock the inserted male head 1 and the inserted female head 2, so that the looseness phenomenon after the insertion of the male head 1 and the female head 2 is avoided, and the stability of optical fiber transmission is ensured.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
