Description

Technical Field

[0001] This utility model relates to the field of automotive electronic control technology, specifically to a phase sensor assembly. Background Technology

[0002] Phase sensors are a collective term for camshaft position sensors and crankshaft position sensors. They are used to detect the engine's valve timing, that is, the crankshaft angle corresponding to the opening and closing times of the intake and exhaust valves according to the engine's working cycle. This information is crucial for determining the engine's ignition timing. Phase sensors achieve their function by detecting the camshaft position angle. Their probes contain detection coils that can sense nearby metal objects, and they have a significant impact on engine performance, economy, and environmental performance.

[0003] The publication number CN210363774U discloses an ABS wheel speed sensor assembly, including a sensor head, a multi-core wire, a sheath, a plug, a terminal, a bushing, a plastic seal, a fixing plate, a sleeve, a plug-in part, heat dissipation holes, a heat-conducting pipe, a miniature heat sink, a dustproof mesh, and a sealing ring. The sensor head is equipped with a fixing plate, one end of which is fitted with a bushing, and the other end with a sleeve. Heat dissipation holes are evenly distributed on one side of the sensor head, and a heat-conducting pipe is installed within each hole, with one end of the heat-conducting pipe communicating with the outside. The inner wall of the heat-conducting pipe... Miniature heat sinks are provided at both the top and bottom, and a dustproof mesh is installed on one side of each miniature heat sink. One end of the sensor head is connected to a multi-core wire via a connector. The multi-core wire includes an inner layer, a heat insulation protective layer, a silicone waterproof layer, and a wear-resistant layer. The structure is simple and provides good protection for the wire. However, this technology does not have a reinforced fixation at the plug terminal. Under long-term use, the plug terminal is prone to loosening. During vehicle operation, vibrations can easily cause the plug terminal to fall off, affecting signal transmission and posing a certain safety hazard. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a phase sensor assembly that addresses the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a phase sensor assembly, including a housing, a fixed disk, and a connecting terminal. The fixed disk is sleeved on the top of the housing, and the connecting terminal is disposed at one end of the fixed disk. The connecting terminal includes a connecting port and a plug-in end disposed within the connecting port. Several fixing claws are hinged on both the upper and lower sides of the connecting port. A hook claw is fixedly provided at the end of each fixing claw. An elastic component is provided inside the fixing claw to keep the fixing claw in a clamping state. The connecting port is also provided with an oblique fixing structure to cause the fixing claw to clamp obliquely.

[0006] By adopting the above technical solution, fixing claws are hinged on the upper and lower sides of the connection port, and hook claws are fixed at the ends of the fixing claws. Combined with elastic components and rhomboid fixing structures, efficient and stable connection of the connection terminals is achieved, enhancing the stability of the connection, preventing loosening or falling off, and simplifying the operation process. At the same time, the design of the rhomboid fixing structure makes the connection tighter, effectively reducing contact resistance and improving the reliability of signal transmission.

[0007] The aforementioned phase sensor assembly can be further configured such that: the fixing claw includes a connecting block hinged to the connection port and a clamping plate disposed on one side of the connecting block and clamped to the external plug-in end; the hook claw is disposed at the end of the clamping plate; the connecting port is provided with hinge blocks on both sides; the hinge blocks and the connecting block are hinged together by providing hinge holes; and a connecting pin is provided in the hinge holes.

[0008] By adopting the above technical solution, the fixed claw design enables flexible rotation through the hinge hole and connecting pin of the connecting block and the connecting port. At the same time, the combination of the snap plate and the hook claw ensures the stable clamping of the external plug end, enhances the stability and reliability of the connection, simplifies the installation process, and improves work efficiency.

[0009] The aforementioned phase sensor assembly can be further configured such that: the elastic component includes a first mounting cavity disposed within the connecting block, the first mounting cavity communicating with a hinge hole, the connecting pin penetratingly disposed within the first mounting cavity, and an abutment spring sleeved within the first mounting cavity, one end of the abutment spring abutting against the inner wall of the first mounting cavity and the other end abutting against the outer wall of the connecting port.

[0010] By adopting the above technical solution, a first mounting cavity is set in the connecting block, and an abutment spring is sleeved in it. The elastic force of the spring is used to keep the fixing claw in a clamping state, which ensures the stability and reliability of the connection. It also allows the fixing claw to flexibly adjust its angle when under force. At the same time, the elastic force of the spring can effectively reduce the wear between the plug end and the fixing claw and extend the service life.

[0011] The aforementioned phase sensor assembly can be further configured such that: the oblique fixing structure includes a first oblique surface disposed on the top of the hinge block; abutment plates that abut against the first oblique surface are fixedly disposed on both sides of the connecting block; an abutment groove for the fixing claw to be embedded and abutted is provided at the edge of the connecting port; a second oblique surface is provided in the abutment groove; and the fixing claw is fixedly oriented obliquely through the first oblique surface and the second oblique surface.

[0012] By adopting the above technical solution, a first inclined surface is set on the top of the hinge block, and abutment plates are fixed on both sides of the connecting block to abut against the first inclined surface. At the same time, an abutment groove with a second inclined surface is opened on the edge of the connecting port to guide the fixing claw to be fixed in the oblique direction, which enhances the clamping force and stability of the fixing claw. It also enables the plug end to automatically align and be firmly positioned during the insertion process, effectively preventing loosening or falling off.

[0013] The aforementioned phase sensor assembly can be further configured such that: a second mounting cavity is provided inside the housing; a mounting plate for mounting a sensor chip is provided inside the mounting cavity; the mounting plate is provided with an embedded groove; the sensor chip is placed in the embedded groove; and the housing is sleeved outside the mounting plate to facilitate the sensor chip being placed inside the second mounting cavity.

[0014] By adopting the above technical solution, a second mounting cavity is set in the housing and equipped with a mounting plate with an embedded groove, so as to achieve stable installation and protection of the sensor chip. The sensor chip is precisely placed in the embedded groove, while the housing is tightly fitted on the outside of the mounting plate, which ensures the stable position of the sensor chip in the second mounting cavity and provides it with additional physical protection, effectively preventing the influence of external environmental factors such as dust and moisture on the sensor performance.

[0015] The beneficial effects of this utility model are as follows: by hinged fixing claws on the upper and lower sides of the connection port and fixing hook claws at the ends of the fixing claws, combined with elastic components and oblique fixing structures, efficient and stable connection of the connection terminals is achieved, enhancing the stability of the connection and preventing loosening or falling off.
