Description

Technical Field

[0001] The utility model relates to an indicator light switch, in particular to an indicator light switch with a wiring harness. Background Art

[0002] At present, most gearboxes are equipped with indicator switches. The function of the indicator switch is to provide electrical signals to the vehicle through the on-off function to display the corresponding gearbox working status. The gearbox generally has indicator switches that display neutral, reverse, high and low gear, power take-off status, retarder status, etc. In this way, the corresponding indicator lights on the dashboard of the cab will show whether the gearbox is in neutral, whether it is in reverse, whether the gearbox is in the high or low gear area, and whether the power take-off is in working state or off state, which helps the driver to judge the vehicle status. The gearbox is generally located in the chassis of the whole vehicle, and the layout of various system components on the chassis is intricate. When connecting the indicator switch of the whole vehicle, it often interferes with other components or is too close, which may cause safety hazards such as knocking the switch.

[0003] The Chinese invention patent with application publication number CN114509668A discloses a vehicle automatic transmission contact shift switch signal detector and its use method. The detector includes a connecting line and a tester host. One end of the connecting line is connected to the tester host, and the other end is connected to the automatic transmission contact shift switch to be tested. The method of use is: step 1, use the connecting line to access the automatic transmission contact shift switch interface; step 2, connect the test wiring plug of the connecting line to the test wiring socket; step 3, turn on the detector switch, and the detector status indicator light will light up; step 4, operate the automatic transmission contact shift switch P, R, N and D to be tested to shift gears, and the corresponding gear signal indicator light will light up, then the test result is normal; step 5, the tester host performs detection signal judgment based on the shift signal and displays the detection result in real time. The above invention uses connecting wires to avoid the various complex parts on the chassis, but it is used in the factory inspection stage, so the tester host and the transmission can be directly connected with connecting wires. When the transmission is installed on the vehicle and leaves the factory, if the transmission is still directly connected with connecting wires, the connecting wires will shake while the vehicle is driving, and it is easy to collide with other parts on the chassis.

In order to facilitate the connection of the pressure switch to the gearbox, the switch housing includes a threaded section 2, a transition section 3, a fastening section 4 and a connecting section 5 which are connected in sequence. The four are coaxial and integrally arranged. The pressure probe 1 is arranged on the outer end surface of the threaded section 2, and the outer surface of the threaded section 2 is provided with a thread that matches the threaded hole on the gearbox, so that the entire pressure switch can be connected and fixed to the gearbox through the threaded section. When the switch housing is connected to the gearbox through the threaded section 2, the pressure probe 1 can be inserted into the gearbox to detect the state of the gearbox.

[0034] The transition section 3 includes a large diameter section and a small diameter section, wherein the small diameter section is connected to the threaded section 2, and the large diameter section is connected to the fastening section 4.

By setting the transition section 3, it is more convenient to process the external thread of the threaded section and design the dimension chain of the entire switch housing. The fastening section 4 with a regular hexagonal structure is more convenient to cooperate with a wrench to rotate the entire switch housing, so as to achieve the effect of more conveniently screwing the threaded section 2 into the threaded hole of the gearbox. If the entire pressure switch has assembly accuracy requirements, the ordinary wrench can be replaced with a torque wrench to achieve fixed torque assembly of the entire pressure switch.

[0035] In order to rotatably connect the pressure switch and the protective cap 6 together without affecting the rotation of the pressure switch, the protective cap 6 adopts a split design, which includes a first protective cap split 61 and a second protective cap split 62, which are spliced ​​along the axial splicing surface to form the protective cap 6, and the first protective cap split 61 and the second protective cap split 62 are respectively provided with a connecting ear, and the two connecting ears are arranged corresponding to each other at the splicing connection of the first protective cap split 61 and the second protective cap split 62, and are both provided with connecting holes, and are connected by a connecting member, which can be a bolt, etc. The entire protective cap 6 is a right-angle elbow structure, one end of which is rotatably connected to the switch housing, and the other end is connected to the flexible hose 8, and a first annular groove 63 is provided on the inner wall of the end rotatably connected to the switch housing, and a first outer convex ring 51 is provided on the outer wall of the connecting section 5 of the switch housing, and the first outer convex ring 51 is located in the first annular groove 63, so that the pressure switch and the protective cap 6 are rotatably connected together through the cooperation of the first outer convex ring 51 and the first annular groove 63, which has a simple structure and is easy to operate.

[0036] One end of the flexible hose 8 is connected to the protective cap 6, and the other end is provided with a wiring harness clip 10. In order to realize the rotational connection between the wiring harness clip 10 and the socket 9, the wiring harness clip 10 also adopts a split structure, which includes a first wiring harness clip split 101 and a second wiring harness clip split 102, and the two are spliced ​​along the axial splicing surface to form the wiring harness clip 10. A second annular groove 103 is provided on the inner wall of the wiring harness clip 10, and a second outer convex ring 91 is provided on the outer wall of the socket 9, and the second outer convex ring 91 is located in the second annular groove 103. In order to prevent dust and the like from entering the flexible hose 8 and affecting the transmission of electrical signals, an abutment ring 92 is axially provided on the second outer convex ring 91, and the top end surface of the abutment ring 92 abuts against the inner side wall of the second annular groove 103, and the outer end surface of the second outer convex ring 91 abuts against the outer side wall of the second annular groove 103, thereby preventing dust from entering the flexible hose 8 from the second annular groove 103. In order to further enhance the sealing effect, a sealing ring 11 is sleeved on the outer wall of the abutment ring 92, and the top end surface of the sealing ring 11 abuts against the inner side wall of the second annular groove 103, and the bottom end surface abuts against the inner end surface of the second outer convex ring 91.

[0037] In this embodiment, the wiring harness 7 is located inside the switch housing, the protective cap 6 and the flexible hose 8. One end of the wiring harness 7 is connected to the pressure probe 1, and the other end is connected to the socket 9. In this way, the electrical signal generated by the pressure probe 1 is transmitted to the socket 9 through the wiring harness 7, and finally transmitted to the vehicle indicator light through the socket 9. The driver can then judge the gearbox status based on the indicator light.

[0038] In this embodiment, the socket 9 adopts an amp type socket. If the whole vehicle requires other types of sockets 9 for electrical signal transmission, because the socket 9 is rotatably connected to the wiring harness clip 10, and the wiring harness clip 10 can be split into two parts and then spliced ​​together along the axial splicing surface, different types of sockets 9 can be replaced according to actual conditions to meet the needs of the whole vehicle.

[0039] When in use, first use a wrench to cooperate with the fastening section 4 of the switch housing to connect the pressure switch to the gearbox, then split the protective cap 6 into two parts, connect the pressure probe 1 to one end of the wiring harness 7, then place the first outer convex ring 51 in the first ring groove 63, and then splice the first protective cap split 61 and the second protective cap split 62 in the horizontal direction; next, split the wiring harness clip 10 into two parts, connect the other end of the wiring harness 7 to the socket 9, and then place the second outer convex ring 91 in the second ring groove 103, and then splice the first wiring harness clip split 101 and the second wiring harness clip split 102. At this time, if there is a crowded part on the chassis, it can be avoided by rotating the switch housing and bending the flexible hose 8. In this way, during the driving of the whole vehicle, even if a bump occurs, the switch housing, the protective cap 6 and the flexible hose 8 can provide protection for the wiring harness 7.

[0040] The embodiments described above are merely descriptions of the specific implementation methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
