Technical Field
[0001] The utility model relates to the technical field of pressure sensors, in particular to a connecting mechanism between a conductor and a conditioning signal circuit board used for a pressure sensor. Background Art
[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 are multiple functional components connected to its body, but it also needs to be connected to it through a conductor in the sensor to achieve electrical connection with the inside and outside of the sensor.
[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 technology is urgently needed to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and provide a connecting mechanism for a conductor and a conditioning signal circuit board for a pressure sensor, so as to solve the technical problems in the prior art of using spring clips for electrical connection inside and outside the sensor, which is prone to poor contact, and the use of cable spot welding, which has high dependence on manual labor, low assembly efficiency, and welding points that are prone to disconnection at a later stage, thereby reducing the service life of the product.
[0006] The above objectives are achieved through the following technical solutions:
[0007] A connecting mechanism between a conductor and a conditioning signal circuit board for a pressure sensor comprises a conductor and a conditioning signal circuit board, wherein the conductor is provided with a conductive pin, and correspondingly, the electrical connection portion of the conditioning signal circuit board is provided with a conductive slot, and the conductor and the conditioning signal circuit board are electrically connected by plugging the conductive pin into the conductive slot.
[0008] Furthermore, the electrical connection portion is arranged at one end of the signal conditioning circuit board, and correspondingly, the conductive slot is a straight through slot opened on the signal conditioning circuit board.
[0009] Furthermore, the outer port of the conductive slot is a wide opening, which is used to guide the conductive pin to slide into the conductive slot.
[0010] Furthermore, the wide opening includes mutually symmetrical oblique sides opened at the outer port of the conductive slot, and the included angle between the two oblique sides is 30° to 145°.
[0011] Furthermore, a conductive pad is provided at the conductive slot for spot welding the conductive pin to the conductive slot.
[0012] Furthermore, the conductive pin is a right-angle pin, comprising a conductive pin supporting portion and a conductive pin plugging portion which are perpendicular to each other, and the conductive pin plugging portion can be plugged into the conductive slot.
[0013] Furthermore, the length of the conductive pin supporting portion is not less than the length of the conductive slot, and the length of the conductive pin plugging portion is less than the length of the conductive pin supporting portion.
[0014] Furthermore, the cross-sections of the conductive pin supporting portion and the conductive pin plugging portion are circular and have the same diameter.
[0015] Furthermore, the conductor is in the shape of a coil spring, and the diameter of the spring wire is the same as the diameter of the conductive pin supporting portion and the conductive pin plugging portion.
[0016] Furthermore, there are three conductive slots, and the three conductive slots are located on the same horizontal line.

[0025] 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.
[0026] like Figure 1 As shown, the present solution provides a connecting mechanism between a conductor and a conditioning signal circuit board for a pressure sensor, comprising a conductor 1 and a conditioning signal circuit board 2, wherein the conductor 1 is provided with a conductive pin 3, and correspondingly, the electrical connection portion 4 of the conditioning signal circuit board 2 is provided with a conductive slot 5, and the conductor 1 and the conditioning signal circuit board 2 are electrically connected by plugging the conductive pin 3 into the conductive slot 5.
[0027] The electrical connection portion 4 is disposed at one end of the signal conditioning circuit board 2 , and correspondingly, the conductive slot 5 is a straight through slot opened on the signal conditioning circuit board 2 .
[0028] like Figure 3 As shown, as a specific embodiment of the present solution, there are three conductive slots 5, and the three conductive slots 5 are located on the same horizontal line.
[0029] As an optimization of this embodiment, the outer end of the conductive slot 5 is a wide opening 8 for guiding the conductive pin 3 to slide into the conductive slot 5 .
[0030] Specifically, the wide opening 8 includes mutually symmetrical oblique edges 9 opened at the outer end of the conductive slot 5, and the included angle between the two oblique edges 9 is 30° to 145°.
[0031] In addition, in this embodiment, a conductive pad 10 is provided at the conductive slot 5 to implement spot welding and fixing of the conductive pin 3 and the conductive slot 5;
[0032] Specifically, the conductive pad 10 is a conductive coating disposed on the inner wall of the conductive slot 5 and adjacent positions, and is used to facilitate contact with the conductive pin 3 to achieve electrical connection. In addition, it is also convenient to perform spot welding after the conductive pin 3 contacts the conductive pad 10, without causing damage to the conditioning signal circuit board 2.
[0033] like Figure 2 As shown, the conductive pin 3 of this embodiment is a right-angle pin, comprising a conductive pin supporting portion 6 and a conductive pin plug-in portion 7 which are perpendicular to each other, and the conductive pin plug-in portion 7 can be plugged with the conductive slot 5;
[0034] It should be noted that, in this embodiment, the conductive pin plug-in portion 7 and the conductive slot 5 have two electrical connection modes:
[0035] The first type is that the conductive pin plug-in portion 7 is plugged into the conductive slot 5 by longitudinal sliding, that is, the conductive pin plug-in portion 7 slides into the opening of the conductive slot 5 and slides along the conductive slot 5 until it contacts the bottom wall of the conductive slot 5 to achieve electrical connection;
[0036] The second type is that the conductive pin connector 7 is laterally connected to the conductive slot 5 , that is, the conductive pin connector 7 is laterally moved from the side of the conditioning signal circuit board 2 until the conductive pin connector 7 is connected to the conductive slot 5 .
[0037] In addition, this embodiment further optimizes the conductive pin 3 as follows:
[0038] The length of the conductive pin supporting portion 6 is not less than the length of the conductive slot 5, and the length of the conductive pin connecting portion 7 is less than the length of the conductive pin supporting portion 6; this structure ensures stable connection while not causing the rest of the conductor 1 to contact the conditioning signal circuit board 2.
[0039] The cross-sections of the conductive pin support portion 6 and the conductive pin connection portion 7 are circular and have the same diameter; the conductor 1 is in the shape of a spiral spring, and the diameter of the spring wire is the same as the diameter of the conductive pin support portion 6 and the conductive pin connection portion 7; this structure can ensure that the resistance values of various parts of the conductor are the same, and the transmission of current or signals is more stable after electrical connection.
[0040] 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.
