Abstract

The utility model relates to an electric connector, which comprises an insulating body, a metal shell body and a plurality of terminals collected in the insulating body. The insulating body comprises a basal body and a tongue plate extending forward from the basal body. The metal shell body is cylindrical. A groove is arranged at the front end of the basal body of the insulating body. A sinking platform is arranged on the metal shell body at a position corresponding to the groove. The sinking platform is collected in the groove. A spacer area is formed at the rear end of the sinking platform and the front end of the groove and can facilitate the deformation of the sinking platform. The sinking platform can effectively prevent the situation of out-of-position plugging when the matched electric connector is butt-connected with the electric connector.

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refer in particular to a kind of have prevent the electric connector that mates pegged graft the position electric connector.

[background technology]

Data transmission cable commonly used, as USB type (Universal Serial Bus, USB) cable or HDMI type (High-Definition Multimedia Interface, HDMI (High Definition Multimedia Interface)) cable or I/O (I/O) cable, generally comprise cable part and coupled electric connector part, interconnective electric connector is composed of by plug and corresponding socket, plug is plugged in the socket, plug and socket all include insulating body, this insulating body is formed with the plurality of terminals accepting groove, this accepting groove can be installed plurality of terminals in interior, when these terminals are in contact with one another, electrically conduct and reach the function of transmission current or data.During plug insertion socket, often make plug be resisted against the insulating body of socket, because of terminal group is loaded in the insulating body and general welding is used, like this because of inserting the excessive reason of strength, when insulating body can make during because of stressed the displacement terminal welding loosening, and then influence the transfer function of terminal.

A kind of patent documentation as China's Mainland license bulletin, its notification number is CN 201004502Y (calling CN ' 502 in the following text), disclosed a kind of I/O connector parent socket, such as its summary in introduction: a kind of I/O connector female seat interface, comprise metal shell and the insulating body that has a row or multi-row attached terminal, on the upper bottom surface of its described metal shell, have towards inside spacing catch, the rear side that the matrix of described insulating body is against described spacing catch suitably gets final product inserting the degree of depth to guarantee plug.When plug inserted female seat, its plug can block by limited catch, and plastic body can not inserted pine and be withdrawed from shell, and what so just guaranteed connector plug and socket well is connected and contacts.

Situation when disclosed socket and plug docks among the above-mentioned patent documentation CN ' 502, can find that the front end of plug metal shell is resisted against spacing catch this moment, find that after deliberation the spacing catch that patent documentation CN ' 502 provides is a kind of plates, when plug insertion socket, this spacing catch is subject to power and deforms, the situation that the matrix of insulating body is pushed so still can take place, and then causes being assembled in the loosening of terminal welding position in it.

In view of above disappearance, a kind of terminal of ad hoc meter welding position is difficult for loosening constitutionally stable electric connector.

[utility model content]

The utility model provides technical problem to be solved to provide the difficult loosening constitutionally stable electric connector in a kind of terminal welding position.

The utility model discloses a kind of electric connector, comprise insulating body, metal shell, some terminals that is contained in the insulating body, insulating body comprises matrix and the hyoplastron that extends forward from matrix, metal shell is tubular, the matrix front end of insulating body is provided with a groove, metal shell is to should groove location forming a heavy stand, and this heavy stand is contained in the groove and this heavy stand front end surpasses matrix foremost, and rear end and groove front end form a spacer region of being convenient to the heavy stand distortion.

Compared to prior art, the matrix front end of the insulating body of the utility model electric connector is provided with a groove, metal shell is to should groove location forming a heavy stand, this heavy stand is contained in the groove and this heavy stand front end surpasses matrix foremost, excessive insertion force was in the blocking-up of heavy stand place and can not be delivered to the insulating body place and then prevent that the terminal welding position from rupturing when rear end and groove front end formed a spacer region of being convenient to the heavy stand distortion and will mate electric connector and dock, so improved the stability of electric connector structure.

[embodiment]

Be each view of the utility model electric connector 100 as shown in Figures 1 to 4.

Electric connector 100 comprises insulating body 1, is located in the plurality of terminals 2 of insulating body 1 and is coated on insulating body 1 outer field metal shell 3.

The hyoplastron 12 that insulating body 1 comprises rectangular base 11, extends forward from matrix 11 front ends.Matrix 11 front center are provided with a groove 111, and this matrix 11 upper and lower surperficial 112,113 protrudes the surface respectively and forms bumping square 117 and trapezoidal projection 114, and lower surface 113 forms anchor slot 115 in trapezoidal projection 114 both sides indents.This insulating body 1 is made of one piece with terminal 2, and the top, precalculated position of terminal 2 is formed with and is three location holes 116 that line style is arranged, and wherein the location hole 116 in foremost can pass for the front end of terminal 2.

Terminal 2 comprises weld part 21, connecting portion 22 and the contact site 23 that is connected in turn, and the arragement direction of three location holes 116 on the direction of extension of terminal 2 and the insulating body 1 is consistent.

Metal shell 3 is tubular, comprise the upper and lower plate 31,32 of pair of opposing and the sidewall 33 of pair of opposing, these upper plate 31 rear ends are formed with narrow square cell body 311, lower plate 32 rear ends are formed with trapezoidal cell body 321, these trapezoidal cell body 321 both sides should be formed with grasp 322 by insulating body 1 anchor slot 115 interior buttons mutually, and the sidewall 33 of metal shell 3 is extended with sagittal flexure strip 331.Groove 111 positions of the matrix 11 of metal shell 3 corresponding insulating bodies 1 form a heavy stand 312, this heavy stand 312 is contained in the groove 111 and this cooperation when finishing, the matrix 11 that heavy stand 312 front ends surpass insulating body 1 foremost, heavy stand 312 rear ends form one with groove 111 front ends and are convenient to the spacer region 30 that heavy stand 312 is out of shape.Lower plate 32 indents of metal shell 3 are formed with the engaging power of platform 323 when improving electric connector 100 butt joints of accepting that protrudes from the metal shell 3.
