Understandably, the part that the second end 342 of this stitch 34 is overlapped on outside shell 31 also can arrange in right angle bending as shown in Figure 4; The second end 342 ends of stitch 34 also can be as shown in Figure 5 opposing and towards the same side of shell 31.
As shown in Figure 8, the electronic device of the utility model the 6th embodiment, comprises shell 41, circuit board 42, at least one electronic devices and components 43 and the several stitch 44 that are electrically connected with circuit board 42; Circuit board 42 and electronic devices and components 43 are arranged in shell 41, and circuit board 42 is provided with and stitch 44 pad 45 one to one, and the first end 441 of each stitch 44 is arranged in shell 41, and near a side that is arranged on a pad 45; The second end 442 of each stitch 44 is drawn and is arranged on outside shell 41; Between the first end 441 of each stitch 44 and corresponding pad 45, be welded and fixed connection, thereby realize being electrically connected between stitch 44 and circuit board 42, need on circuit board 42, not hole, make simple and reduce costs.
This shell 41 is roughly hollow shaped as frame, and open formation of one side bottom opened framework, so that circuit board 42, electronic devices and components 43 etc. are put into wherein.This shell 41 can be by injection mo(u)lding, certainly, and also moulding by other means.Understandable, the cross sectional shape of this shell 41 can be square, rectangle, circle or other shapes, changes shell 41 sizes also can change as required the quantity of stitch 44 time.Shell 41 can adopt the PBT(poly-to stupid dioctyl phthalate butanediol ester) material makes, and has good chemical stability, mechanical strength, electrical insulation characteristics and thermal stability; Certainly, this shell 41 also can be according to demand, adopts other materials to make.
Further, the first end 441 of each stitch 44 is welded on the pad 45 of circuit board 42 between circuit board 42 and the sidewall 411 of shell 41; 442, second end of each stitch 44 is drawn the sidewall 411 of shell 41.
In order to strengthen the steadiness of stitch 44 in shell 41, improve the reliability of this electronic device, the first end of stitch 44 441 can be embedded in sidewall 411 internal faces of shell 41.As shown in Figure 8, in the present embodiment, the first end 441 of stitch 44 convexes with locating piece 413 towards the surface of sidewall 411 internal faces of shell 41, the corresponding locating piece 443 of sidewall 411 internal faces of shell 41 is provided with location notch (not indicating), and the first end 441 of stitch 44 is embedded in sidewall 411 internal faces that are engaged in shell 41 in location notch by locating piece 443.
The shape of locating piece 443 does not limit, and can be the shape such as polygon, circle.Preferably, the size of the size of this location notch and locating piece 443 is substantially equal, and locating piece 443 is closely embedded in location notch.Be embedded into by the locating piece 443 on the first end 441 of stitch 44 on sidewall 411 internal faces of shell 41, not only make between the first end 441 of stitch 44 and shell 41 relative fixing, also make circuit board 42 by being fixedly connected with stitch 44 first ends 441 also can opposite shell 41 fixing, when the rubber seal ability that can prevent casting glue 46 goes down, circuit board 42 be in the interior movement of shell 41, inclination.
The formation that is connected with the second end 442 by first end 441 of each stitch 44.Each stitch 44 is connected with circuit board 42 by first end 441, and 442, second end of each stitch 44 is drawn shell 41 and is set to outside shell 41.Wherein, the second end 442 of stitch 44 is mainly drawn from the sidewall 411 of shell 41.As a kind of preferred implementation, shell 41 can be coated on several stitch 44 by injection mo(u)lding, and make the first end 441 of each stitch 44 be positioned at shell 41, the second end 442 stretches out shell 41, like this, between stitch 44 and shell 41, form assembly closely, improve the reliability of electronic device.
In embodiment, shell 41 also can be made in advance, then assembles with stitch 44.Therefore, on the sidewall 411 of shell 41, corresponding several stitch 44 are provided with several through holes, and the second end 442 of several stitch 44 is drawn shell 41 by corresponding through hole respectively and is arranged on outside shell 41.The internal diameter of through hole equates substantially with the external diameter of stitch 44 second ends 442, thereby avoids, after assembling, between stitch 44 second ends 442 and through hole, leaving gap, ensure assembling more closely, reliable.
The second end 442 of stitch 44 relatively first end 441 is vertically drawn shell 41, and also first end 441 tilts to draw shell 41 relatively.In addition, the second end 442 of stitch 44 also bends in sidewall 411 outside wall surface that are overlapped on shell 41.The second end 442 ends of several stitch 44 can be through bending and towards the same side, is convenient to electronic device and is connected with extraneous electronic component by stitch 44.As shown in Figure 8, in the present embodiment, the relative first end 441 of the second end 442 of stitch 44 is vertically drawn shell 41, and the second end 442 of several stitch 44 to be overlapped on part outside shell 41 be that arc bending arranges, and the end of the second end 442 is in opposite directions and towards the same side of shell 41.
Understandably, the part that the second end 442 of this stitch 44 is overlapped on outside shell 41 also can arrange in right angle bending as shown in Figure 4; The second end 442 ends of stitch 44 also can be as shown in Figure 5 opposing and towards the same side of shell 41.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
