Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that is used for for butt connector grafting.

[background technology]

The novel patent announcement of TaiWan, China has disclosed a kind of electric connector No. 491422, and it mainly comprises insulating body, is immobilizated in the plurality of conductive terminals and the shielding casing of insulating body.This electric connector is welded on the circuit board by the downward weld part that extends of terminal welding foot that extends the insulating body rear end and shielding casing two side, and retain strength mainly concentrates on the lower part of electric connector, promptly near the circuit board place.When butt connector inserts, butt connector can act on the upper and lower side of electric connector insulating body, because the suffered retain strength of electric connector concentrates on the bottom, the top of this electric connector may be moved backward, if overexert, whole electric connector then may recede, thereby causes the weld part of terminal welding foot and shielding casing and the welding between circuit board to be destroyed.

Therefore, be necessary to design a kind of novel electric connector.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector that can firmly be immobilizated in circuit board.

For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, be used for pegging graft for a butt connector, it comprises insulating body, is immobilizated in a receiving space of Gong the butt connector grafting of the plurality of conductive terminals of insulating body, an installed surface and formation, insulating body is provided with the front end face that is positioned at receiving space, described front end face is provided with the boss that extends to receiving space, and the close installed surface of this boss is to keep out butt connector.

Compared with prior art, the utility model electric connector has following beneficial effect: insulating body is kept out with butt connector to the boss that receiving space protrudes out mutually from front end face, can alleviate the stressed energy imbalance of electric connector, thereby electric connector firmly is immobilizated on the circuit board.

[embodiment]

See also shown in Fig. 1,2, the utility model electric connector 100 mainly comprises insulating body 1, is immobilizated in the plurality of conductive terminals 2 of insulating body 1 and is covered in insulating body 1 shielding casing 3 outward.

See also shown in Fig. 3,4, insulating body 1 is one-body molded setting, it comprises the base portion 10 of lengthwise and the hyoplastron 11 that extends forward from base portion 10, the rear end face 13 that base portion 10 has a front end face 12, be oppositely arranged with front end face 12, an end face 14, the bottom surface 15 and a pair of side 16 that are oppositely arranged with end face 14, bottom surface 15 forms an installed surface, and end face 14, bottom surface 15 and side 16 connect front and rear end 12,13.Lengthwise hyoplastron 11 is to protrude out formation from these front end face 12 middle parts forward near end face 14 places, front end face 12 has protruded out pair of projections 121 forward in the two end portions that is positioned at hyoplastron 11 downsides, each boss 121 all is trapezoidal blocks wide at the top and narrow at the bottom, this lays respectively at the both sides of front end face 12 to boss 121, and near 15 places, bottom surface, and the thickness of boss 121 is less, protrudes the weak point of length than hyoplastron 11.Insulating body 1 has extended upward a pair of block 141 from the end face 14 of base portion 10, and is extended with a block 151 downwards from base portion 10 bottom surfaces 15.The rear end face 13 of base portion 10 protrudes out backward from correspondence boss 121 places, two ends, bottom and is formed with holding parts 131, and boss 121 is the same horizontal levels that are positioned at base portion 10 with holding parts 131.In the present embodiment, plurality of conductive terminals 2 and insulating body 1 injection mo(u)lding, its terminal holding parts (not shown) is fixed in the insulating body 1, contact site 21 is contained in the terminal containing slot 111 of hyoplastron 11 belows, and pin portion 22 then extends behind the bottom of insulating body 1 more backward horizontal-extending downwards to weld mutually with circuit board.

Shielding casing 3 is sealing box-shaped bodies that formed by the single piece type metal stamping, and it is provided with a roof 31, a diapire 32 that is oppositely arranged with roof 31 and the pair of sidewalls 33 that is connected this roof 31 and diapire 32.Shielding casing 3 is from front end face 12 assemblings of the body 1 that insulate, to be covered in insulating body 1, its interfere by the interference part 152,161 that is provided with on the internal face of shielding casing 3 and insulating body 1 bottom surface 15 and the two sides 16 and with insulating body 1 fixing mutually, and the corresponding respectively breach 311 of setting on shielding casing 3 roofs 31 and the rear end of diapire 32 of keeping out of block 141,151 by being provided with on the base portion 10, cause insulating body 1 excessively to enter in the shielding casing 3 to prevent to move after shielding casing 3 is excessively.Again shielding casing 3 sidewalls 33 rear end lower are closed on shell fragment 331 bendings that extend at bottom place,, thereby make insulating body 1 and shielding casing 3 held stationary (joining shown in Figure 2) with the holding parts 131 corresponding fixings that protrude out with rear end face 13 bottoms of insulating body 1.The diapire 32 of the shielding casing 3 a pair of weld part 321 that extended back from the both sides, rear end, this weld part 321 can weld mutually with circuit board.At this moment, shielding casing 3 and insulating body 1 common formation one can be accommodated the receiving space 4 (joining shown in Figure 1) of butt connector 200 (joining shown in Figure 5), and front end face 12 is positioned at receiving space 4, and boss 121 and hyoplastron 11 protrude into this receiving space 4.

See also shown in Figure 5ly, butt connector 200 inserts receiving spaces 4, replaces boss 121 until the bottom of butt connector 200 front ends, and the top of butt connector 200 front ends then keeps at a certain distance away with the front end face 12 of insulating body 1.Can be when butt connector 200 inserts to boss 121 generations thrust backward, promptly the bottom of insulating body 1 is produced backward active force, because of electric connector 100 suffered retain strengths mainly concentrate on the bottom, this retain strength can be enough and the active force antagonism that insulating body 1 bottom produced when inserting of butt connector 200.And, the shell fragment 331 that the setting of place, bottom is closed in shielding casing 3 sidewalls 33 rear ends of electric connector 100 is the holding parts 131 corresponding fixings that protrude out with insulating body 1 rear end face 13 bottoms, if boss 121 is not set, when butt connector 200 inserts, the front end of this butt connector 200 can be kept out with the front end face 12 of insulating body 1, because insulating body 1 top is not stabilized fixing, the top of this insulating body 1 can rotate inclination backward, make 3 of insulating body 1 and shielding casings produce loosening phenomenon, and the setting of boss 121, its front end and boss 121 were replaced when butt connector 200 was inserted, the retain strength that the shell fragment 331 that makes power that pushes backward that insulating body 1 bottom is subjected to and insulating body 1 rear end face 13 bottom holding parts 131 be subjected to provides is cancelled out each other, thereby can avoid this insulating body 1 run-off the straight.

Above-mentioned execution mode is the better embodiment of the utility model electric connector.Certainly, the utility model electric connector also can adopt other execution mode, gives unnecessary details no longer one by one herein.
