【Specific embodiment】

Refer to shown in Fig. 1 and Fig. 2, the utility model electric connector 100 is fixed to a circuit board (not to vertically-mounted Diagram).The electric connector 100 includes insulating body 1, the conducting terminal 2 and coated insulation body 1 being assembled in insulating body Metal shell 3.The metal shell 3 is coated on the outside of insulating body and is collectively forming with for docking with insulating body 1 The receiving space 101 of connector plant (not shown).

Refer to shown in Fig. 3 to Fig. 5, the base portion 10 of the insulating body 1 including lengthwise and upward from the top of base portion 10 The hyoplastron 11 for protruding out.From up to down see, the base portion 10 is trapezoidal.The base portion 10 is provided with the block stretched out from its bottom Portion 101, the groove 102 positioned at its lengthwise two ends and two locating dowels 104 extended downwardly from its bottom, the stop section 101 To the excessive assembling of barrier metal housing 3.The groove 102 caves inward from the lengthwise both sides of base portion 10, and the groove Through the bottom surface of base portion 10 not through the top surface of base portion 10.The hyoplastron 11 is upwardly extended from the top surface of base portion 10 and is provided with phase To two interfaces for setting.The lengthwise one end of the hyoplastron 11 is stepped, so as to prevent non-matching connector be erroneously inserted and Play foolproof function.

The conducting terminal 2 is vertically assembled in insulating body 1 and is arranged into two rows along longitudinally.Often row leads Electric terminal 2 includes several signal terminals and several ground terminals, and differential terminal pair is arranged to per two neighboring signal terminal, described Differential terminal by the ground terminal to being separated.The conducting terminal 2 be provided be immobilizated in insulating body 1 fixed part 21, from Contact site 22 and the bending of the opposite side of self-fixed department 21 that the side of fixed part 21 extends straight up extend the welding of insulating body 1 Pin 23, the welding foot 23 is located at the lower section of base portion 10.The fixed part 21 of the conducting terminal 2 vertically extends and part Extend the bottom surface of base portion 10 of insulating body 1, the self-fixed department 21 of the welding foot 23 is along the horizontal direction perpendicular to vertical direction Upper extension.

The fixed part 21 is provided with the hangnail positioned at its both sides, the hangnail be used to the interference engagement of insulating body 1 so that will Conducting terminal 2 is firm to be installed in insulating body 1.The contact site 22 exposed to hyoplastron 11 interface on, to it is right The conducting terminal of connecting connector is in contact.The welding foot 23 is used to be welded on circuit board and is provided with relative upper and lower surface And the horizontal-extending formation free terminal in one end of self-fixed department 21, outside of the free terminal without departing from insulating body 1.

Fixed part 21 of the conducting terminal 2 before insulating body is assembled to is small with the angle that welding foot 23 is bent to form In 90 degree, i.e., the welding foot bending angle of conducting terminal 2 is less than 90 degree.The insulating body 1 be provided with from the bottom surface of base portion 10 to Under protrude out and correspond the boss 103 of welding foot 23 of the conducting terminal 2 and recessed between adjacent two boss 103 Groove, in the bottom surface of the boss 103 is generally aligned in the same plane.

The upper surface of the welding foot 23 for being assembled into insulating body 1 Shi ﹐ conducting terminals 2 when conducting terminal 2 is bottom-up overlaps Shang the boss 103 of the bottom of insulating body 1 ﹐ and using insulating body 1 to the active force of conducting terminal 2 by the folding of conducting terminal 2 Bending angle is strutted to 90 degree；In being generally aligned in the same plane against the bearing surface of welding foot due to the boss 103 of the insulating body 1, So that the welding foot 23 of conducting terminal 2 may also be in same plane.Now the fixed part 21 of the conducting terminal 2 extends absolutely Gap is formed between the part of the bottom surface of base portion 10 of edge body 1 and the boss 103 of corresponding insulating body 1.The conducting end Space is formed between sub 2 welding foot 21 and the bottom surface of base portion 10 of insulating body 1.The grade gap, being provided with for space are beneficial to Conducting terminal 2 is inserted in insulating body 1.

The metal shell 3 is coated on the circular body portion 30 in the outside of insulating body 1 and indulging for main body 30 The fixed pin 32 that both sides long extend downwardly, the outside of the base portion 10 of insulating body 1 is coated on due to the main part 30, is with gold The butt joint interface for belonging to housing 3 is trapezoidal corresponding to the shape of base portion 10.The main part 30 is provided with the bottom positioned at its lengthwise both sides The shell fragment 31 at end, tears on the main body 30 of the shell fragment 31 and is formed and inwardly projection.When metal shell 3 is assembled to from top to bottom During insulating body 1, the bottom of the main part 30 of metal shell 3 is resisted against on the stop section 101 of base portion 10, so as to prevent metal-back The excessively assembling downwards of body 3.The shell fragment 31 is then contained in the groove 102 of the both sides of base portion 10, so as to prevent metal shell 3 upward Depart from the insulating body 1.

Bending angle in the utility model between the fixed part 21 and welding foot 23 of conducting terminal 2 is negative angle, be with When conducting terminal 2 is assembled into insulating body 1, conducting terminal 2 can rely on the support of boss 103 of the bottom of insulating body 1 to snap Pin 23, good coplanar of welding foot 23 such that it is able to realize conducting terminal 2 using the flatness of the bottom of insulating body 1 Degree.Its coplane degree and assembly precision requirement to conducting terminal after punching press 2 simultaneously is low, such that it is able to effective raising efficiency and assembling The stability of processing procedure.

In sum, preferred embodiment of the present utility model is these are only, should not limits of the present utility model with this Scope.I.e. every simple equivalence changes made according to the utility model claims and the utility model description with Modification, all should still belong in the range of the utility model patent covers.
