Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail. Following examples are for illustration of the present invention, but can not be used for limiting the scope of the invention.
As Figure 2-3, the hand brake indicator switch of the present embodiment always becomes to comprise bolt cover 23, push rod 21, return spring 22, union lever 24 and terminal sheath 25, the two ends of union lever 24 are respectively push rod terminal 241 and inserting terminal 242, and bolt cover 23 comprises nut portion 231, column part 232 and tapered segment 233.
Bolt cover 23 is made up of metallic substance, there is good conductivity, its nut portion 231 and tapered segment 233 are positioned at the two ends of column part 232, the outside of column part 232 is provided with screw thread, always become for bolt cover 23 is fixed to hand braking front portion, to overlap vehicle body, penetrating in the middle of bolt cover 23, bolt cover 23 is enclosed within push rod 21;Push rod 21 is made up of insulating material, such as plastics, one end of its nut portion 231 stretching out bolt cover 23 is connected with parking braking handle, its stretch out bolt cover 23 one end of tapered segment 233 be connected with the push rod terminal 241 of union lever 24, push rod 21 can along with the pull-up of parking braking handle or put down bolt cover 23 in move reciprocatingly; As shown in Figure 4, the inside of the outside of push rod 21 and bolt cover 23 is equipped with ledge structure, and return spring 22 is clipped between push rod 21 and bolt cover 23 by two ledge structures cooperations, return spring 22 is in compressed state, and push rod is applied to overlap the elastic acting force of the nut portion 231 of 23 towards bolt by return spring 22.
As shown in Figure 5, the as a whole part of union lever 24, its two ends are respectively push rod terminal 241 and inserting terminal 242, the entirety of union lever 24 is made up of metallic substance, and have good conductivity, push rod terminal 241 encases push rod 21 and stretches out one end of tapered segment 233 of bolt cover 23 and compress, make push rod terminal 241 and push rod 21 that relative displacement not occur, push rod terminal 241 is provided with horn-like opening, the profile of horn-like opening matches with the profile of the tapered segment 233 that bolt overlaps 23, inserting terminal 242 and wire harness termination plug-in unit patch, its structure and model match with corresponding wire harness end connector assembly, owing to inserting terminal 242 to be moved with union lever 24, so inserting terminal 242 motion within the specific limits can not affect the grafting effect of inserting terminal 242 with wire harness end connector assembly, it is can contact with each other and the insert-connecting plate of relatively sliding such as inserting terminal 242 and wire harness end connector assembly, terminal sheath 25 is enclosed within union lever 24, for the protection of with fixed connecting rod 24, it is made up of insulating material, terminal sheath 25 is to the protection position of union lever 24 mainly union lever 24 main body and inserting terminal 242, and push rod terminal 241 can be positioned at outside terminal sheath 25, terminal sheath 25 also facilitates patching of inserting terminal 242 and wire harness termination plug-in unit. above-mentioned push rod terminal 241 be equipped with inserting terminal 242 together with opening vertically, for clamping or loosen the interface size of terminal, so that terminal coordinates closely with other parts.
The principle of work that the hand brake indicator switch of the present embodiment always becomes is: push rod 21 has the trend that moves of nut portion 231 side overlapping 23 towards bolt under the elastic acting force of return spring 22, now, the tapered segment 233 that push rod 21 drives the push rod terminal 241 of the union lever 24 that end connects with it and bolt to overlap 23 contacts, owing to bolt overlaps the inserting terminal 242 of the other end and the wire harness end connector assembly grafting of 23 overlap joint vehicle bodies and union lever 24, be to form the loop of conducting; When push rod 21 with parking braking handle put down and when tapered segment 233 side of overlapping 23 towards bolt is moved, push rod 21 drives the push rod terminal 241 of the union lever 24 that end with it connects to leave the tapered segment 233 of bolt cover 23, and circuit disconnects.
The hand brake indicator switch of this kind of structure always becomes to overcome hand brake indicator switch of the prior art and always becomes owing to connecting by wire between two terminal, the inner copper wire of wire is easy to fracture, thus cause the problem that hand brake indicator switch lost efficacy, the push rod terminals 241 and the inserting terminal 242 that is connected with inserted terminal that overlap 23 cooperations with bolt are separately positioned on the two ends of union lever 24, two terminals are made to form an entirety, the hand braking lamp of this kind of structure opens the light and always becomes the connection between two terminals reliable, not only avoid the risk that wire fractures, hand brake indicator switch is made always to become function more effectively and to stablize, reduce the failure rate of hand braking switch assembly, and the wire eliminated between two terminals, pyrocondensation sleeve pipe, the parts such as PVC sleeve pipe and electric tape, simplify production technique, save production cost.
Embodiments of the invention in order to example and describe for the purpose of and provide, and be not exhaustive or limit the invention to disclosed form. Many modifications and variations are apparent for the ordinary skill in the art. Selecting and describing embodiment is the principle in order to the present invention is better described and practical application, and the those of ordinary skill enabling this area is understood the present invention thus designed the various embodiments with various amendment being suitable for specific end use.
