[0002] Brake pressure sensors are used in ESC systems (electronic stability control systems) and are mainly installed on hydraulic control modules to monitor the pressure of brake fluid. Traditional pressure sensors involve several circuit boards with functional modules, and as the core signal conditioning circuit board, it is mainly used to realize the collection, processing and external output of pressure signals. Therefore, not only multiple functional components are connected to its body, but it is also necessary to electrically connect the circuit board to the external system through conductive parts in order to collect or process the signals collected or processed by each functional unit on the circuit board.

[0003] Currently, the common conductors used to conduct electricity inside and outside the sensor are mostly in the form of spring terminals, but after long-term use, it is very easy for the springs to deform and cause poor contact; another way is to use cable plus spot welding, which not only relies heavily on manpower and has low assembly efficiency; but also in the later use of the pressure sensor, it is very easy for the welding points to fall off due to transportation or external vibration, which invisibly reduces the service life of the pressure sensor, and maintenance requires comprehensive disassembly.

[0004] Therefore, a new coil spring type conductive part has been developed, which can effectively solve the drawbacks of the above-mentioned prior art. However, due to its characteristic appearance structure, it is difficult to assemble it with the sensor, mainly because there is no suitable supporting mechanism to realize modular assembly.

[0015] Furthermore, a virtual circle formed by the protective cover guide column and the buckle is concentric with the bottom surface of the conductor protective cover, and an outer diameter of the virtual circle is not greater than an outer diameter of the bottom surface of the conductor protective cover.

DETAILED DESCRIPTION

[0028] The utility model is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 3 As shown, the present solution provides a conductor guide support mechanism for a pressure sensor, comprising a conductor support 1 for inserting a conductor 14, and a conductor cover 2 that can be snapped with the conductor support 1, and a conductor limiting hole 3 is provided on the conductor cover 2 for the top of the conductor 14 to pass through and limit the conductor 14;

[0030] The conductor support 1 is provided with a conductor insertion hole 4 corresponding to the position of the conductor limiting hole 3. After the conductor 14 is inserted into the conductor insertion hole 4, its two ends are respectively used for electrical connection:

[0031] A cover guide column 5 and a cover buckle 6 are provided on the bottom side of the conductor cover 2, and correspondingly, a conductor support guide groove 7 and a conductor support buckle groove 8 matching the cover guide column 5 are provided on the conductor support 1;

[0032] The vertical guidance and connection of the conductor cover 2 and the conductor support 1 are achieved by plugging the cover guide column 5 into the conductor support guide groove 7;

[0033] The conductor cover 2 and the conductor support 1 are connected by snapping together through the snapping of the cover snapping buckle 6 and the conductor support snapping slot 8 .

[0034] It should be noted that the conductor guiding and supporting mechanism for the pressure sensor provided in this embodiment is suitable for needle-shaped conductors, that is, the outer diameters of the upper and lower ends of the conductor are different. Specifically, when applied to this mechanism, the portion with a larger outer diameter of the conductor will be limited in the conductor plug hole 4, while the portion with a smaller outer diameter of the conductor will pass through the conductor limiting hole 3 to facilitate external electrical connection.

[0035] In this embodiment, the bottom end surface of the conductor protection cover 2 is circular, and correspondingly, the conductor support 1 is cylindrical.

[0036] The protective cover guide column 5 and the protective cover buckle 6 are vertically connected to the bottom end surface of the conductor protective cover 2, and are arranged in a circle along the bottom end surface of the conductor protective cover 2;

[0037] Correspondingly, the conductor support guide groove 7 and the conductor support clamping groove 8 are arranged along the circumference of the upper end surface of the conductor support 1.

[0038] like Figure 1 As shown, as a specific embodiment of the present scheme, there are two protective cover guide posts 5 and one protective cover buckle 6; correspondingly, there are two conductor support guide grooves 7 and one conductor support buckle 8; the two protective cover guide posts 5 and the protective cover buckle 6 are arranged at equal intervals.

[0039] It should be noted that the virtual circle formed by the protective cover guide column 5 and the protective cover buckle 6 in this embodiment is concentric with the bottom surface of the conductor protective cover 2, and the outer diameter of the virtual circle is not larger than the outer diameter of the bottom surface of the conductor protective cover 2; this structure can ensure that the outer sides of the conductor protective cover 2 and the conductor support 1 can be sleeved by the cylindrical pressure sensor housing, and the outer edges of each component can contact the inner wall of the pressure sensor housing to form a stable socket.

[0040] As an optimization of the protective cover guide column 5 and the conductor support guide groove 7 in this embodiment, the inner side edge of the protective cover guide column 5 is an arc-shaped edge, and correspondingly, the conductor support guide groove 7 is an arc-shaped groove opened from the upper end surface to the side edge of the conductor support 1;

[0041] Specifically, the protective cover guide column 5 and the conductor support guide groove 7 structure of this structure can not only realize flexible plug-in, but also the supporting surface or edge is not easy to deform. While having the guiding function, after the conductor protective cover 2 and the conductor support 1 are snap-connected with each other, they can also provide a circumferential clamping force, so that the connection between the conductor protective cover 2 and the conductor support 1 is more secure.

[0042] And as Figure 2 and 3 As shown, the protective cover buckle 6 in this embodiment includes a buckle root 9, a buckle body 10 and a buckle foot 11 that are interconnected. The buckle root 9 is vertically connected to the bottom end surface of the conductor protective cover 2, and the buckle body 10 is used to penetrate the conductor support slot 8. The buckle foot 11 penetrates the conductor support slot 8 and then buckles with the bottom end of the conductor support slot 8 to achieve longitudinal locking.

[0043] The conductor support slot 8 includes a buckle root groove 12 opened from the upper end surface to the side of the conductor support 1, and a buckle through groove 13 arranged on the bottom wall of the buckle root groove 12 and connected thereto;

[0044] It should be noted that the shape of the buckle root groove 12 in this embodiment corresponds to the buckle root 9, and when the conductor cover 2 and the conductor support 1 are buckled together, it is used to hide the buckle root 9; and the buckle through groove 13 is a through groove that can penetrate the bottom end surface of the conductor support 1, and is used for the buckle foot 11 and the buckle body 10 to pass through.

[0045] In addition, as a limitation of the structure, the inner diameter of the buckle slot 13 is larger than the outer diameter of the buckle foot 11 , and the inner diameter of the buckle slot 13 is smaller than the outer diameter of the buckle root 9 ; and the length of the protective cover buckle 6 is larger than the length of the protective cover guide column 5 .

[0046] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
