Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples 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 assembly of the present embodiment comprises bolt sleeve 23, push rod 21, return spring 22, connecting rod 24 and terminal jacket 25, the two ends of connecting rod 24 are respectively push rod terminal 241 and inserting terminal 242, and bolt sleeve 23 comprises nut portion 231, column part 232 and tapered segment 233.
Bolt sleeve 23 is made up of metal material, there is good electric 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, for bolt sleeve 23 is fixed to hand braking anterior assembly, to overlap vehicle body, penetrating in the middle of bolt sleeve 23, bolt sleeve 23 is enclosed within push rod 21; Push rod 21 is made up of insulating material, as plastics, its one end of stretching out the nut portion 231 of bolt sleeve 23 is connected with parking brake handle grip, the push rod terminal 241 of its one end and connecting rod 24 of stretching out the tapered segment 233 of bolt sleeve 23 is connected, and push rod 21 can move reciprocatingly in bolt sleeve 23 along with the pull-up of parking brake handle grip or put down; As shown in Figure 4, the outside of push rod 21 and the inside of bolt sleeve 23 are equipped with ledge structure, and return spring 22 is clipped between push rod 21 and bolt sleeve 23 by two ledge structures cooperations, return spring 22 is in compressive state, and return spring 22 pairs of push rods apply towards the elastic acting force of the nut portion 231 of bolt sleeve 23.
As shown in Figure 5, as a whole of connecting rod 24, its two ends are respectively push rod terminal 241 and inserting terminal 242, the entirety of connecting rod 24 is made up of metal material, and have good electric conductivity, push rod terminal 241 encases push rod 21 and stretches out one end of the tapered segment 233 of bolt sleeve 23 and compress, push rod terminal 241 and push rod 21 is made relative displacement not to occur, push rod terminal 241 is provided with flare openings, the profile of flare openings matches with the profile of the tapered segment 233 of bolt sleeve 23, inserting terminal 242 and wire harness termination plug-in unit patch, its structure and model match with corresponding wire harness end plug connector, because inserting terminal 242 will move with connecting rod 24, so inserting terminal 242 motion within the specific limits can not affect the grafting effect of inserting terminal 242 and wire harness end plug connector, if inserting terminal 242 and wire harness end plug connector are can contact with each other and the insert-connecting plate of relative sliding, terminal jacket 25 is enclosed within connecting rod 24, for the protection of with fixed connecting rod 24, it is made up of insulating material, protection position mainly connecting rod 24 main body and the inserting terminal 242 of terminal jacket 25 pairs of connecting rods 24, and push rod terminal 241 can be positioned at outside terminal jacket 25, terminal jacket 25 also facilitates patching of inserting terminal 242 and wire harness termination plug-in unit.Opening vertically together with above-mentioned push rod terminal 241 is equipped with inserting terminal 242, for clamping or loosen the interface size of terminal, so that terminal coordinates closely with miscellaneous part.
The operation principle of the hand brake indicator switch assembly of the present embodiment is: push rod 21 has the trend towards the nut portion 231 side movement of bolt sleeve 23 under the elastic acting force of return spring 22, now, push rod 21 drives the push rod terminal 241 of connecting rod 24 that end connects with it to contact with the tapered segment 233 of bolt sleeve 23, because bolt sleeve 23 overlaps vehicle body and the inserting terminal 242 of the other end of connecting rod 24 and the grafting of wire harness end plug connector, to form the loop of conducting; When push rod 21 with parking brake handle grip put down and move towards tapered segment 233 side of bolt sleeve 23 time, the push rod terminal 241 of the connecting rod 24 that push rod 21 drives end with it to connect leaves the tapered segment 233 of bolt sleeve 23, and circuit disconnects.
The hand brake indicator switch assembly of this structure overcomes hand brake indicator switch assembly of the prior art owing to being connected by wire between two terminal, the inner copper wire of wire is easy to fracture, thus the problem causing hand brake indicator switch to lose efficacy, the push rod terminal 241 coordinated with bolt sleeve 23 and the inserting terminal 242 be connected with inserted terminal are separately positioned on the two ends of connecting rod 24, two terminals are made to form an entirety, the connection that the hand braking lamp of this structure opens the light between assembly two terminals is reliable, not only avoid the risk that wire fractures, make hand brake indicator switch assembly function more effectively with stable, reduce the failure rate of parking switch assembly, and the wire eliminated between two terminals, heat-shrinkable T bush, the parts such as PVC sleeve pipe and insulating tape, simplify production technology, save production cost.
Embodiments of the invention provide in order to example with for the purpose of describing, and are not exhaustively 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 in order to principle of the present invention and practical application are better described, and enables those of ordinary skill in the art understand the present invention thus design the various embodiments with various amendment being suitable for special-purpose.
