[0032] Methane detectors are generally used in gas wells to detect whether there is a methane gas leak. The detection principle of methane detectors is: methane detectors use pump suction technology to measure the concentration of methane gas. Methane detectors contain a pump and a sensor. The function of the pump is to suck ambient air into the detector through the pump suction method. Then the sensor measures the methane gas concentration in the sucked air and converts the result into an electrical signal output. If the methane concentration is detected, an alarm signal is issued.

[0033] The methane detector is installed in a shell, a control board is arranged in the shell, and an antenna assembly is generally arranged outside the shell, and the antenna assembly can provide signals for the device. In the related art, the antenna assembly is electrically connected to the control board through a wire, however, the fixing effect of the wire in the related art is poor, and the connection stability between the antenna assembly and the control board is low.

[0034] Based on the above technical problems, the present application provides a gas detector housing and a gas detector. The gas detector housing includes a housing body and a sealing connector. A sealing member is provided at a position of the housing body near the through hole. The sealing member is used to seal the gap between the through hole and the sealing connector and fix the wire passing through the lead hole. In this way, the sealing connector can fix the wire passing through and improve the fixing effect of the wire; at the same time, the sealing member can further fix the wire after passing through and maximize the fixing and sealing effect of the wire, thereby helping to improve the connection stability between the antenna assembly and the control board, ensuring that the antenna assembly provides a stable signal to the electric control board. In addition, it also helps to prevent the wire from being pulled out from the outside.

[0045] In some embodiments, the sealing connector 120 may be provided with a lead hole 123, so that the wire passes through the lead hole 123 and is connected to the electronic device 210 in the cavity 111. The lead hole 123 can constrain and limit the wire, which helps to further fix the wire and prevent the wire from loosening and affecting the connection stability between the electronic device 210 and the antenna assembly. Moreover, when the number of wires includes at least two or more, the multiple wires are passed through multiple lead holes 123 one by one, which helps to avoid problems such as mutual entanglement between the multiple wires and further ensure the connection stability of the wires.

[0046] In order to further improve the fixing effect of the wire, in this embodiment, referring to Figure 3 and Figure 4 As shown, a seal 130 may be provided near the through hole 112 of the shell body 110. When the wire passes through the lead hole 123 and is connected to the electronic device 210, the seal 130 is used to seal the gap between the through hole 112 and the sealing connector 120, and fix the wire passing through the lead hole 123. In this way, the wire after passing can be further fixed, and the fixing and sealing effect of the wire can be improved to the greatest extent, thereby helping to improve the connection stability between the antenna assembly and the control board, and ensuring that the antenna assembly provides a stable signal to the electronic control board. Exemplarily, the seal 130 can be a sealant, or the seal 130 can be a potting glue, etc., which is not limited in this embodiment. In this way, the cured sealant or potting glue can further improve the fixing and sealing effect of the wire.

The specific opening position of the first rib 114 may be set according to actual needs. In addition, the connection method between the first rib 114 and the shell body 110 is not limited. For example, the first rib 114 and the shell body 110 may be connected by bonding, or the first rib 114 and the shell body 110 may be integrally formed. This embodiment does not limit this.

[0049] In some embodiments, reference Figure 3 and Figure 4 As shown, the top of the first rib 114 may have a first opening 1141 , the first opening 1141 is connected to the first sealing groove 113 , and the first opening 1141 is used for the sealing member 130 to be filled into the first sealing groove 113 , wherein the size and position of the first opening 1141 are not limited.

[0050] In one possible implementation, referring to Figure 4 As shown, the top of the first rib 114 is not lower than the top of the through hole 112, which helps to enhance the sealing effect of the gap between the through hole 112 and the sealing connector 120, and can seal the entire sealing connector 120 after the sealing connector 120 is assembled.

[0051] For example, refer to Figure 4 As shown, the height of the first sealing groove 113 can be set to H, the aperture of the through hole can be set to D, and the height H of the first sealing groove 113 is not less than the aperture D of the through hole. The specific values ​​can be set according to actual conditions.

[0052] In some embodiments, reference Figure 3 and Figure 4 As shown, the top of the housing body 110 may be provided with a housing opening 115, and the first opening 1141 is opposite to the housing opening 115, wherein the size and position of the housing opening 115 are not limited and may be specifically provided according to actual conditions. By providing the housing opening 115, it is convenient for operators to fill the seal 130 into the first sealing groove 113.

The above method can also achieve the fixation of the wire.

[0054] The specific opening position of the second rib can be set according to actual needs. In addition, the connection method between the second rib and the shell body 110 is not limited. For example, the second rib and the shell body 110 can be connected by bonding, or the second rib and the shell body 110 can be integrally formed. This embodiment does not limit this.

This arrangement helps to prevent the sealing connector 120 from protruding from the outer wall of the housing body 110 after assembly, which helps to improve the aesthetics of the device.

[0056] Among them, there is no limitation on the groove width, groove diameter, etc. of the groove 116, which can be set according to actual needs. In addition, there is no limitation on the opening shape of the groove 116. For example, the cross-section of the groove 116 can be square or circular, etc., which is not limited in this embodiment.

[0057] In some embodiments, the through hole 112 is disposed at the bottom of the groove 116, so that it is convenient to pass the wire through and can avoid the wire passing path from crossing other devices or wires. In addition, it can reduce the vibration and swing of the wire, thereby ensuring the stability of the wire transmission signal to the greatest extent possible.

[0058] In some embodiments, the number of through holes 112 may include multiple through holes 112.

Accordingly, the number of wires can include two, the number of sealing connectors 120 can include two, and the two sealing connectors 120 are respectively provided with lead holes 123, and the external antenna components can include two, so that one antenna component is connected to the electrical component through one of the wires, and the other antenna component is connected to the electrical component through another wire, and the two antenna components do not interfere with each other, which helps to improve the stability of signal transmission.

[0059] In one practicable manner, the through hole 112 can be disposed on the side wall of the housing body 110 and close to the bottom of the housing body 110. In this way, the wire can also be threaded, and the wire threading path can be prevented from crossing other devices or wires, thereby ensuring the stability of the wire transmission signal.

[0060] It should be noted that, in this embodiment, the arrangement of the through hole 112 includes but is not limited to the above-mentioned manner, and can be specifically arranged according to actual conditions.
