Abstract

The invention relates to an electric connector. The electric connector comprises a shell, a conductive element arranged in the shell, and a tripping mechanism arranged on the outer side of the shell, wherein chutes are formed on the two outer wall surfaces of the shell; the tripping mechanism is provided with a pull ring and arm parts which are positioned in the chutes and do not protrude out of the two outer wall surfaces; arc ejection parts are arranged at the free tail ends of the arm parts, pull the pull ring to drive the arm parts to slide backwards, and protrude out of the two outer wall surfaces of the shell; and bumps which protrude out of the ejection parts are formed in the chutes. The bumps can lift elastic parts when the arm parts slide backwards, so that interference between the ejection parts and the inner walls of the chutes is avoided.

[embodiment]

Fig. 1 to Fig. 4 has disclosed electric connector 100 of the present invention.Electric connector 100 comprises housing 10, be assembled in the conducting element 20 in the housing and be installed on the release gear 30 of hull outside.

Please referring to Fig. 1 and Fig. 2, housing 10 is made by metal material, and it comprises upper shell 11 and the lower house 12 that cooperates with it, and upper and lower casing has relative two mating surfaces 101,102, and when assembling was finished, two mating surfaces overlapped mutually.This housing 10 has the open front 103 that is square and rounded after-opening 104, inserts for butt connector (not shown) and cable (not shown), and forward and backward opening is formed jointly by upper and lower casing 11,12.Upper shell 11 is provided with a pair of screw 111 that connects himself, and screw 111 is near the rear end of upper shells 11, and lower house 12 corresponding positions also are provided with screw (not shown), and this screw and non through hole only run through the mating surface 102 of lower house.

Upper and

lower casing

11,12 includes a base portion and two, and wherein two base portions form respectively upper and lower wall 13 from the vertically extending part of base portion, then cooperate two sidewalls 14 that form housing from the vertically extending part of base portion.Above-mentioned screw is formed at upper and lower wall 13, and sheet metal 40 is attached at upper wall 13, and its a pair of through hole 41 that rushes riveting formation overlaps with screw 111, and a pair of nut 50 passes through hole 41, finally is fixed in the screw 111.Upper and lower casing is respectively equipped be clasped mutually draw-in groove 113 and grab 114 with respect to the other end both sides of screw, and grab and draw-in groove run through respectively two mating surfaces 101,102.Cooperate and buckle structure by bolt, upper and lower casing is fixed together reliably.

In conjunction with Fig. 3, in the present embodiment, conducting element 20 is a circuit board, and this circuit board is installed on housing 10 front ends, and makes the circuit board front end be exposed to open front 103.Circuit board 20 roughly is square, and its upper and lower surface is equipped with some Copper Foils and forms input 21 and the output 22 that is positioned at the front and back end, and input 21 is positioned at open front 103, and input and output are electrically connected.Circuit board 20 is provided with semi-circular cut-out 23 in the both sides near output 22, and this otch is matched with the semicolumn 112 that upper shell 11 correspondence positions are provided with, thereby makes circuit board 20 be installed on housing 10.

The connecting portion 32 that release gear 30 comprises draw ring 31, link to each other with draw ring and from extended two arms 33 that are the arm shape of connecting portion, arm 33 comprises the rake 332 that main part 331, autonomous body extend forward and the limiting section 333 that connects the rake end, limiting section 333 is roughly horizontal, certainly, main part 331 and rake 332 can one, and namely the angle of inclination of rake end is less gets final product.Above-mentioned sidewall 14 is provided with the chute 141 that is arranged with from its outside wall surface 143, and this chute front end (near open front 103 places) is provided with the less rearward end 1413 of the larger leading section of the degree of depth 1411, the degree of depth and connects both tippers 1412.Leading section 1411 both sides are provided with the stopper slot 1414 that is communicated with chute 141.Above-mentioned arm 33 is contained in the chute 141, and its shape is corresponding with chute to do the movement of fore-and-aft direction along chute.3331 of the lugs that the both sides of limiting section 333 project out are contained in and limit in the groove 1414, and lug 3331 is slidingly matched and is limited to and limits in the groove 1414, not only from fore-and-aft direction restriction arm 33, and can prevent that arm breaks away from chute.Chute 141 is provided with the face of keeping out 142 at contiguous stopper slot 1414 places, and limiting section 333 front ends are resisted against on the face of keeping out 142.Can clearly find out from Fig. 3, rake 332 interval tippers 1412 certain intervals are so that it has certain elasticity, when release gear moves backward, drive 333 of rake 332 and limiting sections mobile backward, limiting section is slightly outwards mobile because running into tipper.

In conjunction with Fig. 4, the free terminal of arm 33 (namely foremost) also is provided with the ejection part 334 of arc, and this ejection part comprises the jut 3341 of arc and the end 3342 that extends from jut.When free state, ejection part does not protrude out the outside wall surface 143 of housing, and at release gear during to front slide, 334 outstanding outside wall surface 143 of ejection part.When butt connector inserts, the shell fragment of butt connector (not shown) extension that slopes inwardly before backward, thus be resisted against on the face of keeping out 142, prevent that butt connector breaks away from electric connector.And the pulling draw ring is when moving, and ejection part 334 protrudes out outside wall surface and outwards ejects shell fragment, shell fragment is broken away from keep out keeping out of face 142, thereby so that butt connector breaks away from electric connector.Terminal spring 60 two ends are sheathed on the circular hole 321 that connecting portion 32 is provided with, the protuberance that intermediate elastic portion then is provided with by upper wall 11 (not shown) tension, and the elastic force that produces can make release gear recover initial position.Intilted terminal 3342 sidewalls of avoiding ejection part scratch butt connector.

In conjunction with Fig. 3 and Fig. 4, described chute also has and is positioned at the resettlement section 1415 that leading section 1411 and width diminish, and this resettlement section is used for accommodating above-mentioned ejection part 334.Chute is provided with the projection 1416 that is positioned at the resettlement section and protrudes to ejection part, and projection is positioned at the front side of the face of keeping out 142, and the front end of close ejection part 334.The inclined-planes 1417 that this projection 1416 is provided with and chute 141 is connected gently, and this inclined-plane 1417 is just in time towards the end 3342 of ejection part.Can be clearly seen that among Fig. 4, release gear not when pulled, projection 1416 is not connected to ejection part 334, the end 3342 of ejection part is not connected to the internal face of chute yet.When arm 33 during in chute 141 interior slip, ejection part 334 also can the 1415 interior slips in the resettlement section, and ejection part 334 can not crossed this projection 1416 when sliding in front and back.When pulling back draw ring, elastic portion 333 is slided to forward direction in resettlement section 1415, and inclined-plane 1417 can lift ejection part 334, especially terminal 3342, reduce the interference between elastic portion and the chute internal face, thereby reduced pulling capacity, also reduced the scratch of surface of shell simultaneously.
