Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described further.
Embodiment: referring to Fig. 2 to Fig. 4.
A kind of improvement of PPTC surface mounting structure, comprise PPTC chip 1, top electrode 8, bottom electrode 9 and support 1, the middle part of described support 1 is provided with the installing hole for PPTC chip 1, described support 1 be provided with top electrode 8 mounting grooves and bottom electrode 9 mounting grooves, top electrode 8 is connected with lower surface with the upper surface of PPTC chip 1 respectively with bottom electrode 9.
The utility model by arranging top electrode 8 mounting grooves and bottom electrode 9 mounting grooves on support 1, so just, can be first fixedly top electrode 8 and bottom electrode 9, in the time of fixedly, can adopt grafting, also can adopt injection molding mode, as whole plate upper/lower electrode 9 is placed in injection forming mold, then the mold-closing injection shaping base.After PPTC chip 1 inserts in the installing hole of support 1, PPTC chip 1 respectively with top electrode 8 and bottom electrode 9 butts, top electrode 8, bottom electrode 9 form adding of PPTC chip 1 are held to structure simultaneously, can be preferably fixing PPTC chip 1, and form conducting.After installing chip, its chip is caught up with electrode 8 surfaces and can be encapsulated as required insulating cement and make moist or oxidation to prevent chip and electrode.
Further, described top electrode 8 comprises clamping part 81, connecting portion 82, lower sticking part 83; Described upper clamping part 81 exposes to support 1, and described connecting portion 82 is arranged in top electrode 8 mounting grooves, and lower sticking part 83 is fitted with the lower surface of support 1.
Further, described upper clamping part 81 is L-shaped.
The elasticity of L-shaped upper clamping part 81 is better, has larger elasticity.
Further, described bottom electrode 9 comprises clamping part 93, middle interconnecting piece 92, sticking part 91; Wherein clamping part 93 is positioned at installing hole and fits with the lower surface of installing hole, and described middle interconnecting piece 92 is arranged in bottom electrode 9 mounting grooves, and sticking part 91 is fitted with the lower surface of support 1.
Further, described clamping part 93 is L-shaped.
Clamping part 93 is positioned at installing hole, makes bottom electrode 9 can be good at contacting with PPTC chip 1 by its clamping part 93, and clamping part 93 is L-shaped simultaneously, makes clamping part 93 have good elasticity, is conducive to the clamping to PPTC chip 1.
Be only below the application's preferred embodiment, equivalent technical solutions on this basis still falls into the application protection range.
