Best: the angle between described plate and the stator is 45 degree.
Described plate is straight plate; Described contact chip is the downward opening arc sheet of going up.
Described fixed head is fixed in the limit, left side of base plate; Offer at least one through hole on the base plate; The left surface of each through hole extends into a following electroconductive elastic sheet to the right.
Described down electroconductive elastic sheet comprise an opening up following arc sheet and one extend the following spacer that forms left by arc sheet terminal part down.
Described fixture comprises that several grabs and several are opened in the hole clipping on the earth terminal, and the number of grab and the number of hole clipping equate; Described grab is fixedly arranged on the base plate bottom surface; Grab is connected in respectively in the corresponding hole clipping.
Describedly be in the most significant end of the last electroconductive elastic sheet that freely stretches and be in distance between the least significant end of the following electroconductive elastic sheet that freely stretches greater than the distance between radome and the earth terminal.
By above-mentioned description to the utility model structure as can be known, compare with background technology, the beneficial effects of the utility model are:
One, connector of the present utility model, the angle between plate and the stator are acute angle, when having loaded onto the circuit board of radome with the direction assembling that is parallel to circuit board, can guarantee board side smooth and easy to assembling process;
Its two, connector of the present utility model, electroconductive elastic sheet is closely against radome all the time by elastic force on it, following electroconductive elastic sheet is closely against earth terminal all the time by elastic force, can guarantee between radome and the earth terminal that conduction is connected all the time, assurance ground connection is good;
Its three, connector of the present utility model has a plurality of electroconductive elastic sheets and a plurality of electroconductive elastic sheets down gone up, and can guarantee that ground connection is good;
Its four, connector of the present utility model processing is simple, low cost of manufacture.

Embodiment
A kind of Elecrical connector of being convenient to assemble as shown in Figure 1, 2, 3, has a conductive pedestal 1, a plurality of electroconductive elastic sheet 2 and fixture 3 of going up.The Elecrical connector of present embodiment is formed by the thick tin bronze plate manufacturing of 0.3mm, and its electric conductivity is better, elastic performance good.
Pedestal 1 comprises a conductive base plate 11 and a conductive fixed head 12; Fixed head 12 is fixedly linked in limit, base plate 11 left side.Offer a plurality of rectangular through-hole 111 on the base plate 11 side by side, the number of the number of through hole 111 and last electroconductive elastic sheet 2 equates.Each rectangular through-hole 111 all has side, left, right, front and rear.The left surface of each through hole 111 extends into a following electroconductive elastic sheet 13 to the right, and the structure of electroconductive elastic sheet 13 is all identical under all.Following electroconductive elastic sheet 13 comprise an opening up following arc sheet and one extend the following spacer that forms left by following arc sheet terminal part.
The structure of electroconductive elastic sheet 2 is all identical on all.Last electroconductive elastic sheet 2 all has a plate 21 and a contact chip 22.Plate 21 is straight plate, and all plate 21 bottoms are connected into a whole plate by accessory plate, and the upper surface of fixed head 12 is fixed in its bottom; Contact chip 22 is the downward opening arc sheet of going up, and its upper end by plate 21 stretches out and forms.Angle between plate 21 and the stator 12 is an acute angle, and this acute angle is preferably 45 degree.
Shown in Fig. 2,8, fixture 3 comprises three pairs of grabs 31 and three pairs of hole clippings 32; Three pairs of grabs 3 are fixedly arranged on the bottom surface of base plate 11, arrange the position that sets firmly of grab according to the actual needs of earth terminal; In the present embodiment, each two grab to grab 3 all is symmetrical arranged, three pairs of forward and backward, middle parts that are arranged at the bottom surface of base plate 11 respectively.Hole clipping 32 is opened on the earth terminal.
Grab 31 is connected in respectively in the corresponding hole clipping 32, and makes base plate 11 be abutted against in earth terminal, and following electroconductive elastic sheet 13 is in compressive state.
Be in the most significant end of the last electroconductive elastic sheet 2 that freely stretches and be in distance between the least significant end of the following electroconductive elastic sheet 13 that freely stretches greater than the distance between radome and the earth terminal.Electroconductive elastic sheet 13 all is closely against earth terminal under each; Electroconductive elastic sheet 2 all is closely against radome on each.
Shown in Fig. 4,5,6,7,8, during assembling, three pairs of grabs 31 of connector to be packed in three pairs of hole clippings 32 of framework, connector just is stuck on the framework 4 (its material is steel plate, i.e. earth terminal), makes base plate 11 be abutted against in earth terminal; Loaded onto the circuit board 5 of radome again with the direction assembling that is parallel to circuit board, circuit board is locked on the framework, the radome of circuit board has the decrement of 1.5mm to connector.After circuit board was seated, the elasticity of the tin bronze material of connector made electroconductive elastic sheet 2 compressive deformations, thereby produced certain bounce, thereby guaranteed the radome of circuit board and fully contacting of framework.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
