The utility model content

Technical problem to be solved in the utility model is to provide a kind of stability good brake lamp switch for motor vehicle at the above-mentioned state of the art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of brake lamp switch for motor vehicle is characterized in that comprising

Peg graft and overlap;

A pair of contact is located at aforementioned grafting and is put, and each contact comprises the elastic contact part that is positioned at the cover front end face of pegging graft and stretches out the inserting foot of the cover rearward end of pegging graft;

Swivel nut, the hollow screw portion that has sleeve part and extend to be provided with by sleeve part one end, this sleeve part is sheathed on aforesaid grafting cover front end face and the elastic contact part of aforementioned contact is covered;

Mast is inserted in the hollow screw portion of aforementioned swivel nut and can moves around; And

Return unit acts on aforementioned mast all the time and forces the mast head to leave aforementioned elastic contact part.

The setting of sleeve part and hollow screw portion is preferably as follows connection mode: described sleeve part one end face has two embedded holes, and accordingly, described hollow screw portion one end has two embedding projections that cooperate with aforementioned embedded hole setting-in.

As preferably, described return unit is a compression spring, and it is outer and be positioned at hollow screw portion that this compression spring is placed in described mast, and described mast middle part convexes with a force section for aforementioned compression spring effect.

Be provided with the assembly cavity that is provided with for described contact in the described grafting cover, described contact middle part has the side direction card division that is clamped in aforementioned assembly cavity inwall.Contact is provided with more firm.

Compared with prior art, advantage of the present utility model is: the pedestal and the cover of pegging graft are integrated in one, parts such as lead connection and insulation sleeve have been cast out, structure is more succinct, the further miniaturization of volume, the installing space in car significantly reduces, and need not soldering simultaneously, so easy burn-out and blowing not guarantees normal permanent use of stoplight stop lamp.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figures 2 and 3, the brake lamp switch for motor vehicle in the present embodiment comprises peg graft cover 1, a pair of contact 5, swivel nut 10, mast 4 and return unit 7.

The cover 1 of pegging graft is supporting with being electrically connected of stoplight stop lamp, a pair of contact 5 is located on the cover 1 of pegging graft, each contact 5 comprises the elastic contact part 51 that is positioned at cover 1 front end face of pegging graft and stretches out the inserting foot 52 of cover 1 rearward end of pegging graft that elastic contact part 51 has elasticity because of having curved portions 54.Swivel nut 10 has sleeve part 2 and extends the hollow screw portion 3 that is provided with by sleeve part 2 one ends, and this sleeve part 2 is sheathed on cover 1 front end face and the elastic contact part 51 of contact 5 covered of pegging graft.
