[0030] See also Figure 1-Figure 5 The embodiment of the utility model provides a cylinder connector 100, which can be used for but not limited to a transmission cylinder body, so as to realize the electrical connection between the sensing circuit and the control system.

[0031] The through-wall connector 100 includes a shell 10, a plurality of through-wall terminals 20 and an airtight component 30; a plurality of the through-wall terminals 20 are inserted into the shell 10, and both ends of the through-wall terminals 20 protrude from the shell 10 and form a connecting structure 21, and the connecting structure 21 is used to realize the electrical connection of the through-wall terminals 20; the airtight component 30 includes a first seal 31, and the first seal 31 is arranged on the shell 10, and a plurality of the through-wall terminals 20 are arranged through the first seal 31, and the first seal 31 seals the peripheral side of the through-wall terminal 20.

[0032] In the utility model, when the through-cylinder connector 100 is installed on the upper cylinder body, one end of the through-wall terminal 20 extends into the cylinder body, and the wiring harness in the cylinder body is electrically connected to the connecting structure 21 at this end, thereby realizing the electrical connection between the sensing circuit and the through-cylinder connector 100; the other end of the through-wall terminal 20 is located outside the cylinder body, and the wiring harness outside the cylinder body is electrically connected to the connecting structure 21 at this end, thereby realizing the electrical connection between the through-cylinder connector 100 and the control system; and the through-cylinder connector 100 is also provided with an airtight component 30, and the first sealing component 31 of the airtight component 30 is provided on the shell 10, so that several through-wall terminals 20 all pass through the first sealing component 31, so that the first sealing component 31 seals the peripheral side of the through-wall terminal 20, thereby ensuring good airtightness when the through-wall terminal 20 is penetrated in the shell 10. By using the through-cylinder connector 100 provided by the utility model, the female terminals inside and outside the cylinder body are eliminated, the volume of the through-cylinder connector 100 is greatly reduced, the wiring steps and installation methods are simplified, and the through-cylinder connector 100 has good airtightness and can maintain a stable electrical connection, thereby solving the technical problem in the prior art that the through-cylinder connector 100 is large in size, occupies more space, and is not conducive to installation.

[0033] It should be noted that the use of the through-cylinder connector 100 provided in the embodiment of the utility model can reduce the number of switching times, thereby solving the problem of the through-cylinder connector 100 having a large number of switching times and insufficient connection efficiency in the prior art.

[0034] In addition, the through-cylinder connector 100 provided in the embodiment of the utility model has a simple structure and simplifies the production process and assembly process, thereby solving the problem in the prior art that the through-cylinder connector 100 has a complex process that is not conducive to mass production and has high product processing costs.

[0035] In some specific embodiments, there are 16 through-wall terminals 20 , and the 16 through-wall terminals 20 are arranged in two rows, with each row including 8 through-wall terminals 20 .

[0036] In some specific embodiments, see Figure 3 The housing 10 is provided with a first mounting groove 11, and the first sealing member 31 is arranged in the first mounting groove 11. That is, a plurality of through-wall terminals 20 are arranged through the bottom of the first mounting groove 11, and the first sealing member 31 is arranged in the first mounting groove 11, so that the first sealing member 31 can seal the peripheral side of the through-wall terminal 20, and at the same time, the position of the first sealing member 31 is limited by the first mounting groove 11.

[0037] Herein, a tooling jig may be used to pour silica gel into the first installation groove 11 , and then the silica gel is allowed to stand and solidify to form the first sealing member 31 .

[0038] In some specific embodiments, see Figure 3 The bottom protrusion of the first mounting groove 11 forms a plurality of reinforcing rib structures 13, and the plurality of reinforcing rib structures 13 are arranged in a matrix and extend to be connected to the groove wall of the first mounting groove 11, so that the shell 10 still maintains high strength after the first mounting groove 11 is opened, thereby improving the stability of the shell 10.

[0039] In one embodiment, see Figure 2 and Figure 5 , the airtight component 30 also includes a second seal 32 disposed on the housing 10, the second seal 32 is disposed around a plurality of the through-wall terminals 20, and the second seal 32 is used to seal against the cylinder body. In this embodiment, by disposing the second seal 32 of the airtight component 30 around a plurality of through-wall terminals 20 on the housing 10, when the through-cylinder connector 100 is installed on the cylinder body, the second seal 32 abuts between the housing 10 and the cylinder body, and seals the gap between the housing 10 and the cylinder body, further realizing the sealed installation of the through-cylinder connector 100 relative to the cylinder body; thereby protecting the electrical connection between the through-wall terminal 20 and the wiring harness in the cylinder body, making the through-cylinder connector 100 smaller in size and more stable and easy to use.

[0040] The second sealing member 32 may be made of silicone.

[0041] The cooperation of the second sealing member 32 and the first sealing member 31 forms an airtight system, so that after the through-cylinder connector 100 is installed on the cylinder body, the through-cylinder connector 100 and the cylinder body have good airtightness and can maintain a stable electrical connection.

[0042] In some specific embodiments, see Figure 3 The housing 10 is formed with a second mounting groove 12, and the second sealing member 32 is disposed in the second mounting groove 12. The second mounting groove 12 is used to limit the second sealing member 32, thereby preventing the second sealing member 32 from deflecting and ensuring the sealing effect of the second sealing member 32.

[0043] In some specific embodiments, see Figure 3 The second mounting groove 12 and the first mounting groove 11 are arranged on the same side of the housing 10, that is, the second mounting groove 12 and the first mounting groove 11 are both arranged on a side surface of the housing 10 facing the cylinder body.

[0044] In some specific embodiments, see Figure 3 The groove wall of the second mounting groove 12 is protruded to form a plurality of clamping ribs 14, and the plurality of clamping ribs 14 are arranged at intervals along the circumference of the second mounting groove 12. When the second sealing member 32 is inserted into the second mounting groove 12, the plurality of clamping ribs 14 press against the second sealing member 32, thereby increasing the clamping force of the second mounting groove 12 on the second sealing member 32, and ensuring that the second sealing member 32 is stably arranged in the second mounting groove 12.

[0045] In some specific embodiments, see Figure 4 The connection structure 21 includes a wiring hole 211, which is formed by the end surface depressions at both ends of the through-wall terminal 20. Specifically, the wiring harness inside and outside the cylinder body is respectively inserted into the wiring holes 211 at both ends of the through-wall terminal 20, so that the two ends of the through-wall terminal 20 can be electrically connected to the wiring harness inside and outside the cylinder body.

[0046] In some specific embodiments, after the wire harness is inserted into the wiring hole 211 , the wire harness and the through-wall terminal 20 may be connected together by welding.

[0047] In some specific embodiments, see Figure 4 The connection structure 21 further includes a welding section 212, and the welding section 212 passes through the wiring hole 211 and intersects with the end face of the through-wall terminal 20. Specifically, after the wire harness is inserted into the wiring hole 211, solder is applied to the welding section 212 and the wire harness, so that the wire harness can be stably welded to the through-wall terminal 20 to form a sensing signal system.

[0048] In some specific embodiments, see Figure 4The connection structure 21 further includes an observation hole 213, which is disposed on the peripheral side of the through-wall terminal 20 and is connected to the wiring hole 211. Specifically, when the wiring harness is inserted into the wiring hole 211, the connection between the observation hole 213 and the wiring hole 211 allows observation of whether the wiring harness is properly inserted. After the wiring harness is properly inserted, the welding section 212 and the wiring harness are connected by soldering, thereby improving the stability of the connection between the wiring harness and the through-wall terminal 20.

[0049] In some specific embodiments, see Figure 4 and Figure 5 The peripheral side of the through-wall terminal 20 is also protruded to form a clamping portion 22, and the clamping portion 22 is embedded in the housing 10. Therefore, there is a mutual clamping effect between the clamping portion 22 and the housing 10, which improves the stability of the through-wall terminal 20 being inserted into the housing 10 and prevents the through-wall terminal 20 from being separated from the housing 10.

[0050] In some specific embodiments, see Figure 2 and Figure 3 The housing 10 is formed with a mounting hole 15. Specifically, by connecting a fixing member such as a screw through the mounting hole 15 and the cylinder body, the through-cylinder connector 100 can be installed relative to the cylinder body.

[0051] In some specific embodiments, mounting holes 15 are formed at both ends of the housing 10 to improve the mounting stability of the housing 10 .

[0052] In one embodiment, see Figure 2 and Figure 5 The cylinder connector 100 further includes a bushing 40, which is clamped into the mounting hole 15. The bushing 40 protects the housing 10 on the basis of realizing the mounting function.

[0053] In some specific embodiments, the housing 10 and the bushing 40 are molded together at one time.
