[embodiment]

Shown in Fig. 1 to 4, a kind of high density electrical connector 100 that embodies the utility model creation that is disclosed as, it can be installed on the circuit board (not shown), and can cooperate with a butt connector (not shown).This electric connector 100 comprises the insulating body 200 that is provided with interface 21, insulation keeper 300, be installed on insulating body 200 and keeper 300 plurality of conductive terminals 400, and keeper 300 is fixedly connected on two shield blade 500,600 of insulating body 200.Two shield blade 500,600 are immobilizated in insulating body 200 and keeper 300 relative both sides respectively, thereby keeper 300 is fixed in insulating body 200.For ease of cooperating with butt connector, described insulating body 200 is provided with the lead 23 that is in the one end position and protrudes interface 21.

See also Fig. 3 and Fig. 4, two contact arms 41 that conducting terminal 400 is provided with the connecting portion 40 that vertically extends perpendicular to interface 21, continue to extend to interface 21 from connecting portion 40, continue the elastic mounting part 45 that extends to support sector 43 that the direction opposite with contact arm 41 extended and self-supporting portion 43 from connecting portion 40.Connecting portion 40 comprises the two side 401,403 that parallel longitudinal extends and connects the connecting wall 405 of two side 401,403 that aforementioned two contact arms 41 are respectively from a wherein sidewall 401,403 extensions.The butt joint terminal (not shown) that insulating body 200 is provided with terminal hole 20, one butt connectors (not shown) of accommodating conducting terminal 400 can insert in the terminal hole 20 and be held between two contact arms 41.Keeper 300 is provided with the location hole 30 of perforation, and support sector's 43 parts of described each terminal 400 are contained in location hole 30, and elastic mounting part 45 extends location hole 30, thereby can insert interference engagement in the conductive through hole that circuit board designs in advance.

Insulating body 200 is provided with the step 202 that presses on connecting wall 405 close contact arm 41 1 end faces 406 at the madial wall of terminal hole 20.In addition, described support sector 43 is provided with the shoulder 435 towards connecting portion 40, and insulating body 200 also is provided with the step 204 that presses on this shoulder 435.Described support sector 43 is the wall shape extends, and it is provided with the reinforcement 431 to side protrusion and longitudinal extension.Support sector 43 extends from a sidewall 403 of connecting portion 40.Described support sector 43 is provided with turnover wall 433, and this turning point 433 makes support sector 43 transfer with elastic mounting part 45 and is aligned in the center of connecting wall 405 as for longitudinal direction, is beneficial to like this and will acts on the force transmission of connecting wall 405 to elastic mounting part 45.Shoulder 435 vertically also is being aligned in elastic mounting part 45, promptly also is beneficial to apply the elastic mounting part 45 of active force in terminal 400.
