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, is assembled in a pair of anti-error plug-in unit 3 of insulating body 1 and is covered in insulating body 1 shielding casing 4 outward.

See also shown in Fig. 2,3, insulating body 1 is one-body molded setting, the rear wall 11 that it is provided with front end face 10, be oppositely arranged with front end face, diapire, the roof 12 and a pair of side 13 that are oppositely arranged with diapire.Front end face 10 forms an interface, and depression has the host cavity 101 that can accommodate butt connector 200 (joining shown in Figure 5) on it.Roof 12 is concaved with accommodation space 121 respectively downwards in its outside wall surface two ends, and this accommodation space 121 is in running through this roof 12 to be connected with host cavity 101 near front end face 10 places, and accommodation space 121 is in being provided with holddown groove 122 near rear wall 11 places.Roof 12 is provided with the groove 123 of the front end face 10 that runs through insulating body 1 forward in inner wall surface thereof end edge middle part, groove 123 runs through the internal face of roof 12, be communicated with host cavity 101, the two opposite side walls front end of groove 123 is in convexing with relative protuberance 124 respectively near front end face 10 places, and the end face of this protuberance 124 is inclined guide faces 125.The fore-end of groove 123 upwards connects the outside wall surface of roof 12, forms fluting 126, and this fluting 126 is one with groove 123, and fluting 126 is positioned at groove 123 tops, and so, groove 123 is communicated with host cavity 101 and fluting 126.Terminal containing slot 14 runs through the rear wall 11 of insulating body 1 and the internal face of diapire, and forms groove 141 on rear wall 11, forms holding slot 142 on the internal face of diapire.

Each conducting terminal 2 comprises holding parts 20, bends elastic contact part 21 that extends to form and the pin portion 22 of extending vertically downward from holding parts 20 rear ends backward from holding parts 20 front ends.Conducting terminal 2 is to be assembled into from the Hou end face of body 1 of insulating, its holding parts 20 is contained in holding slot 142, and interfere and be fixed in the terminal containing slot 14 by protruding thorn on the holding parts 20 201 and holding

slot

142,21 of elastic contact parts pass groove 141 and protrude into host cavity 101, to electrically connect with butt connector 200 (joining shown in Figure 5), insulating body 1 extends in 22 in pin portion, welds with circuit board.Each anti-error plug-in unit 3 comprises that body 30, the holding parts 31 that extends straight down from body 30 1 ends reach the pushing portion 32 that is inclined upwardly and extends from body 30 other ends, one end of body 30 contiguous pushing portions 32 extends stopper 301 in the inboard, this stopper 301 can be kept out the less butt connector of size and be inserted to reach the anti-mis-insertion effect, its concrete start principle is a prior art, originally is in this and does not give unnecessary details one by one.Anti-error plug-in unit 3 is to be assembled in accommodation space 121 downwards from the roof 12 of body 1 of insulating, its holding parts 31 is fixed in holddown groove 122 with the anti-error plug-in unit 3 stable insulating bodies 1 that are immobilizated in, and the end that pushing portion 32 and body 30 are provided with stopper 301 then passes accommodation space 121 and extends into host cavity 101 with being communicated with the place of host cavity 101.

See also shown in Figure 4, shielding casing 4 comprises a roof 40, with the antetheca 41 of roof 40 adjacency and from 41 liang of lateral borders of antetheca two side 42 of forming of vertical extent backward, wherein the fluting 126 of roof 40 corresponding insulating bodies 1 is provided with breach 401, antetheca 41 is corresponding with interface 10, offer on it and host cavity 101 corresponding opening, these opening two middle side parts are extended with a pair of shell fragment 411 backward relatively, these shell fragment 411 ends convex with abutting part 412, this abutting part 412 can with butt connector 200 butts.Shielding casing 4 is front end face 10 assemblings from the body 1 that insulate, this shielding casing 4 is kept out mutually by the projection 127 that is convexly equipped with on its breach 401 rear portions and insulating body 1 roof 12, and holds hole 421 corresponding buttons by the button that is provided with on the two side 42 and hold button on the insulating body 1 and hold retaining sheet 413 buttons that piece 131, antetheca 41 lower edge both sides extend back and hold the two side of corresponding recessed channel 15 that is provided with in insulating body 1 bottom surface and shell fragment 411 clamping insulating bodies 1 and be immobilizated in insulating body 1 outer (joining shown in Figure 1).

See also shown in Fig. 5,6, comprise base portion 201 with butt connector 200 that the utility model electric connector 100 is complementary, from recede upwardly extending button gripping arm 202 and be connected the connecting portion 203 of base portion 201 and button gripping arm 202 of base portion 201 front ends.Button gripping arm 202 both sides are extended with block 204, and block 204 is positioned at connecting portion 203 tops relatively.When butt connector 200 inserted electric connector 100, button gripping arm 202 was inserted groove 123 and is slotted 126, protuberance 124 interference engagement that are convexly equipped with in the sidewall of connecting portion 203 and the groove 123; After butt connector 200 inserts fully, connecting portion 203 is contained in groove 123,202 part diagonally extendings of button gripping arm are gone in the fluting 126, block 204 is positioned at the top of protuberance 124,124 of protuberances are kept out the Hou end face 205 in connecting portion 203, and butt connector 200 can not break away from from host cavity 101.In the present embodiment, the stopper 204 of button gripping arm 202 is positioned at the top of protuberance 124, and promptly the button gripping arm 202 of this butt connector 200 does not play button and holds effect, but cooperates the two fix of realization with connecting portion 203 by the protuberance 124 of electric connector 100.Certainly, also can still have button to hold under the prerequisite of effect and set up protuberance 124 in existing button gripping arm 202, even button gripping arm 202 unexpected fractures, protuberance 124 still can be kept out mutually with connecting portion 203, can not cause butt connector 200 to get loose, and the equal further fixing butt connector 200 of the active force that produces of abutting part 412 strains of the active force that produces by pushing portion 32 strains of anti-error plug-in unit 3 and shielding casing 4.

If in the time of will extracting butt connector 200, can be earlier squeeze buckle gripping arm 202 downwards, at this moment, stopper 204 both sides can move down along the guiding face 125 of protuberance 124, thereby outwards push insulating body 1, make insulating body 1 plastic deformation and remove keeping out of 124 pairs of connecting portions 203 of protuberance, butt connector 200 safety are extracted.Because be easy to relative with the interference of 203 of connecting portions of protuberance 124 removed in the present embodiment, so also can directly outwards pull out butt connector 200 without squeeze buckle gripping arm 202, make connecting portion 203 cross protuberance 124 and butt connector 200 is extracted.Because butt connector 200 can need not squeeze buckle gripping arm 202 and directly extracts from electric connector 100 in the present embodiment, therefore at electronic installation that employing has the utility model electric connector 100 with after butt connector is connected, when the cable of its butt connector is subjected to pulling more energetically unexpectedly, this electronic installation can be directly and butt connector disconnect, thereby can avoid as can not in time disconnecting generation such as the situation of dropping damage because of electronic installation and butt connector in the prior art.

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.
