Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, and in particular to a wire harness connector structure for smart gas meters. Background Technology

[0002] Most household gas meters have now been upgraded to smart electronic gas meters, such as ultrasonic gas meters and MEMS thermal gas meters. These meters require transmission wires to connect the internal electronic equipment to the external components. Furthermore, since the gas fills the meter casing during measurement, special treatment is needed for the transmission wire connectors to prevent leakage from the transmission holes. In some cases, a flexible elastomer can be used to wrap the transmission wire as a sealing connector. However, this method of wrapping with an elastomer is prone to loosening and detachment after a certain period of use, leading to seal failure and ineffective protection. Utility Model Content

[0003] The purpose of this utility model is to provide a wiring harness connector structure for smart gas meters in order to solve the problem of poor sealing effect of the wiring pin sealing joint.

[0004] To achieve the above objectives, this utility model provides a wiring harness connector structure for a smart gas meter, comprising:

[0005] The terminal block has multiple connection holes, and the sidewalls of the connection holes are provided with limit grooves.

[0006] A connector pin, which passes through the connection hole, with its two ends extending out of the corresponding surfaces of the connector body, and the connector pin having a threaded section;

[0007] A sealant layer is provided, through which the connector pin is connected to the connector body. The sealant layer is formed by the adhesive filling the connection hole and the limiting groove.

[0008] As a further description of the above technical solution:

[0009] The terminal block is installed inside the through hole of the housing.

[0010] As a further description of the above technical solution:

[0011] The housing is provided with a sealing groove, and the through hole is located at the bottom of the sealing groove.

[0012] As a further description of the above technical solution:

[0013] A protective cover is provided on the sealing groove, and the protective cover is snapped into the sealing groove.

[0014] As a further description of the above technical solution:

[0015] The protective cover and the housing are filled with hot melt adhesive, which is located in the sealing groove.

[0016] As a further description of the above technical solution:

[0017] The protective cover has an upwardly protruding groove corresponding to the position of the terminal block.

[0018] As a further description of the above technical solution:

[0019] The protective cover is provided with an injection hole.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the setting of the limiting groove makes the connection between the sealing layer and the terminal block more stable, and the sealing layer is less likely to fall off from the terminal block. The sealing layer covers the threaded section on the connector pin, which can improve the sealing effect between the sealing layer and the connector pin. This solves the problem of poor sealing effect of the connector pin sealing joint and improves safety. Attached Figure Description

[0033] Please see Figure 1-4 This utility model provides a wiring harness connector structure for smart gas meters, comprising:

[0034] The terminal block 1 has multiple connection holes 2, and the sidewalls of the connection holes 2 are provided with limit grooves 3;

[0035] The connector 4 passes through the connecting hole 2, and its two ends extend out of the corresponding surfaces of the connector body 1. The connector 4 has a threaded section.

[0036] The sealing layer 5 is used to connect the 4-pin connector to the connector body 1. The sealing layer 5 is formed by the glue filling the connection hole 2 and the limiting groove 3.

[0037] The terminal block 1 is disposed within the through hole 7 of the housing 6. In actual use, the terminal block is secured within the through hole, facilitating the fixing of the terminal block.

[0038] The housing 6 is provided with a sealing groove 8, and the through hole 7 is located at the bottom of the sealing groove 8. The sealing groove is formed by bending the housing upwards and then concave downwards, which can improve the sealing effect.

[0039] A protective cover 9 is provided on the sealing groove 8, and the protective cover 9 is snapped into the sealing groove 8. Hot melt adhesive 10 is filled between the protective cover 9 and the housing 6, and the hot melt adhesive 10 is located in the sealing groove 8. After the terminal block is installed, hot melt adhesive is filled to reseal the terminal block and the housing, and then the protective cover is snapped into the sealing groove to protect the hot melt adhesive.

[0040] The protective cover 9 has an upwardly protruding groove 11 corresponding to the position of the terminal block 1. This can increase the thickness of the hot melt adhesive filling, thereby improving the sealing effect.

[0041] The protective cover 9 is provided with an adhesive injection hole 12. This allows for adhesive filling after the protective cover is installed, preventing adhesive from overflowing into the sealing groove and reducing waste. The protective cover also has a corresponding through hole for the wiring pin to pass through.

[0042] Working principle: First, insert the connector pin into the connection hole of the connector body. Then, fill the gap between the connector pin and the connector body with glue. After completion, snap the connector body into the through hole of the housing (specifically, the housing of the gas meter). Then, snap the protective cover into the sealing groove. Finally, fill the sealing groove with hot melt glue through the glue injection hole to complete the installation of the connector body. The limiting groove ensures a more stable connection between the sealant layer and the connector body, preventing the sealant layer from falling off. The sealant layer covers the threaded section on the connector pin, improving the sealing effect between the sealant layer and the connector pin. This solves the problem of poor sealing effect of the connector pin joint, resulting in good safety.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
