Compared with prior art, the utlity model has following beneficial effect: described contact arm is contained in the side pilot trench but does not protrude the design that side connects face, the contact loss of conducting terminal in the docking operation of avoiding, and described be contained in the bottom pilot trench and protrude inner bottom surface by pressure arm and contact arm formation lever, after butt connector is inserted into pressing position, prize contact arm and protrude into and patch chamber, thereby realize being electrically connected.
The accompanying drawing explanation
Fig. 1 is the three-dimensional combination figure of the utility model electric connector, and one of them conducting terminal separates from the body that insulate.
Fig. 2 is the cross-sectional schematic before the utility model electric connector and butt connector connect.
Fig. 3 is that the contact arm of the utility model electric connector protrudes into the schematic diagram that patches chamber.
Embodiment
Refer to shown in Fig. 1 to Fig. 3, introduce in detail the embodiment of the utility model electric connector 100 below in conjunction with accompanying drawing.The electric connector 100 of the present embodiment is board to board connector, uses for butt connector 200 and pegs graft, and described electric connector 100 comprises having the insulating body 10 that patches chamber 101 and the some conducting terminals 20 that are contained in insulating body 10.
Described insulating body 10 comprises that having side connects connecting sidewall 102 and having the diapire 103 of inner bottom surface 1031 of face 1021, and described sidewall 102 and the diapire 103 of connecting is respectively equipped with and the side pilot trench 1023 and the bottom pilot trench 1033 that patch chamber 101 and communicate.Described conducting terminal 20 comprises base portion 201 and the contact arm 202 gone out from base portion 201 bifurcateds and by pressure arm 203, described contact arm 202 is contained in side pilot trench 1023 but does not protrude side and connects face 1021, describedly by pressure arm 203, be contained in bottom pilot trench 1033 and protrude inner bottom surface 1031, when described when by pressure arm 203, being subject to pressed by external force and shrinking back to inner bottom surface 1031, described contact arm 202 and make contact arm 202 protrude into the described lever that patches chamber 101 by common formation of pressure arm 203.Described contact arm 202 is contained in side pilot trench 1023 but does not protrude the design that side connects face 1021, the contact loss of conducting terminal 20 in the docking operation of avoiding, and described be contained in bottom pilot trench 1033 and protrude inner bottom surface 1031 form levers by pressure arm 203 and contact arm 202, after butt connector 200 is inserted into pressing position, prize contact arm 202 and protrude into and patch chamber 101, thereby realize being electrically connected.
Described conducting terminal 20 is according to a drawing of cross section profile shape, thereby better bulk strength can be provided, and avoids running quickly and bursting in the leverage process; Described contact arm 202 is greater than near the width of described contact arm 202 base portion 201 at the width of free terminal, increases by this elasticity of contact arm 202; The free terminal of described contact arm 202 is provided with zigzag contact site 2021(ginseng Fig. 3 towards patching chamber 101 1 sides), thereby provide the grasping force while coordinating with the conducting terminal of butt connector 200 to contact with stable.Described conducting terminal 20 also comprises and is parallel to the fixed part 204 that side connects face 1021, and described insulating body 10 is provided with to be positioned at and patches the holder 104 of 101 outsides, chamber to accommodate described fixed part 204.Described base portion 201, fixed part 204, contact arm 202 and totally be " mountain " shape by pressure arm 203, this fixed part 204 for whole conducting terminal 20 better retain strength fixedly is provided in, the conducting terminal 20 that has the structure of prizing for this is also a kind of laborsaving optimal design with avoiding terminal fatigue.
