Description
Technical field
The present invention relates to the switching device field of automobile, particularly a kind of BLS.
Background technology
Back-up lamp is one of mostly important safety member in vehicle complete vehicle, and the quality of its quality directly influences making for vehicle
Use performance.And BLS is the safety component in automotive transmission.In the past, the BLS of external and domestic automobile
Repair rate it is (the often bright or defect such as do not work occur) higher, user's complaint is quite serious, just because of this slight switch, seriously
Have influence on credit worthiness of the user to automobile brand quality.As shown in figure 1, the BLS of prior art is main by housing 2, top
Bar 1, plug 4, contact 7 and power line 5 are constituted, and the end outer side face of push rod 1 is provided with electrode slice, when be linked into reverse gear when, top
Bar 1 is that point is contacted between contact 7 and electrode slice after ejecting, and the end of contact 7 still connects when automobile is linked into other gears
Touch on push rod, using a period of time after, the abrasion of electrode slice and contact can be caused, so as to cause contact to be contacted with electrode slice
It is bad, so that back-up lamp does not work, the service life of existing this BLS typically only 50,000 times.
The content of the invention
A kind of deficiency the invention aims to solve prior art problem, there is provided BLS.
To reach above-mentioned purpose, the present invention is implemented according to following technical scheme：
A kind of BLS, including housing, push rod, plug, contact and power line, plug are fixed on the chamber in housing
In body, contact is set to two panels and the end of contact is connected through plug with power line, and push rod is axially disposed within housing, push rod
Front end extend to hull outside, the end of push rod is connected by the first spring with the end face of plug, solid on the push rod end
Surely there is projection, second spring, one end of second spring and the chamber for being fixed on housing are arranged with the push rod on projection end face
In body, the projection end face is respectively provided on two sides with electrode slice, and the front end of contact is provided with for the right angle with electrode slice joint
Flanging.
Further, the end of the contact and power supply wire bonding.
Compared with prior art, it is face when the electrode slice of BLS of the present invention is connected with the right angle flanging of contact front end
Contact, contact area is big, is not in the situation of loose contact, and automobile is when being linked into other gears, the right angle of contact front end
Flanging other any location contacts not with push rod, do not result in abrasion, increased the service life of whole BLS, this hair
Bright BLS access times can reach 800,000 times.
Brief description of the drawings
Fig. 1 is the structural representation of the BLS of prior art.
Fig. 2 is structural representation of the invention.
Specific embodiment
With reference to specific embodiment, the invention will be further described, the illustrative examples invented herein and explanation
It is for explaining the present invention but not as a limitation of the invention.
A kind of BLS as shown in Figure 2, including housing 2, push rod 1, plug 4, contact 7 and power line 5, plug 4
It is fixed in the cavity in housing 2, contact 7 is set to two panels and the end of contact 7 is connected through plug 4 with power line, touches
The end of piece 7 is preferably to weld with power line 5, and push rod 1 is axially disposed within housing 2, and the front end of push rod 1 is extended to outside housing 2
Portion, the end of push rod 1 is connected by the first spring 3 with the end face of plug 4, and projection 8, projection 8 are fixed with the end of the push rod 1
Be arranged with second spring 9 on push rod 1 on end face, one end of second spring 9 be fixed in the cavity of housing 2, it is described
The end face of projection 8 is respectively provided on two sides with electrode slice 6, and the front end of contact 7 is provided with for the right angle flanging with the joint of electrode slice 6
71。
The operation principle of BLS of the invention：When automobile is linked into non-reversing gear, push rod 1 is due to being pressurized axially to shell
Moved in cavity in body 2, now, electrode slice 6 on projection 8 not with the joint of contact 7, and when be linked into reverse gear when, the end of push rod 1
Portion moves to outside housing 2 vertically, and now because the electrode slice 6 on projection 8 is just contacted with the formation face of contact 7, back-up lamp is bright.
Technical scheme is not limited to the limitation of above-mentioned specific embodiment, and every technology according to the present invention scheme is done
The technology deformation for going out, each falls within protection scope of the present invention.
