Description
TECHNICAL FIELD
[0001] The utility model relates to sensor technical field especially relates to a kind of elastic terminal conductive module for sensor. BACKGROUND
[0002] Brake pressure sensor is a very important component in automobile braking system, which bears multiple key roles. For example, it can control the oil pressure of the braking system with oil pressure booster, ensuring the efficient operation of the braking system during work. At the same time, it can also detect the pressure of the accumulator, and immediately issue an alarm if the accumulator pressure is abnormal, reminding the driver to handle it in time. In addition, the brake pressure sensor can also sense the closing or opening signal of the output oil pump, ensuring that the oil pump works at the right time and monitoring the hydraulic pressure change in the braking system in real time, providing protection for the braking safety of the vehicle.
[0003] The electric connection end of the sensor generally uses spring terminals, which have a certain elasticity and can achieve elastic insertion of the sensor. In addition, the spring terminals in traditional sensors generally have three, and the polarity of the three spring terminals is usually determined according to the type of the sensor and the wiring standard. Generally speaking, in a three-wire sensor, the spring terminals may represent the positive electrode (VCC), the negative electrode (GND), and the signal output end (OUT) respectively. The commonly used spring terminals are in a straight line, with one end as the outer electric connection end and the other end as the inner electric connection end. The outer electric connection ends of the three spring terminals form an outer electric connection surface with the insertion hole, and the inner electric connection ends of the three spring terminals form an inner electric connection surface with the insertion hole. Among them, the outer electric connection surface is used to resist the three spring blades in the insertion hole to achieve electrical connection, while the inner electric connection surface is used to resist the solder pad on the internal circuit board of the sensor to achieve electrical connection.
[0004] However, when the spring blade end face formed by the three spring blades in the insertion hole is greater than or less than the outer electric connection surface, the electrical connection between the outer electric connection surface and the spring blade end face cannot be achieved. To solve this problem, the common method is to reset the sensor that matches the spring blade end face, which results in high development cost.
[0005] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. UTILITY MODEL CONTENT

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0031] like Figures 1-4 As shown, a flexible terminal conductive module for a sensor includes an upper terminal support 1 and a lower terminal support 2 that can be plugged into each other. The upper terminal support 1 has an external electrical connection socket 101 and a terminal reversing groove 102 that are interconnected. The lower terminal support 2 has an internal electrical connection socket 201. The external electrical connection socket 101, the terminal reversing groove 102 and the internal electrical connection socket 201 are interconnected to form a receiving cavity for limiting and embedding the spring terminal 3.
[0032] The spring terminal 3 includes an external power connection part 301, a terminal switching part 302, and an internal power connection part 303 connected to each other. One side of the terminal switching part 302 is connected to the external power connection part 301, and the other side of the terminal switching part 302 is connected to the internal power connection part 303. The external power connection part 301 and the internal power connection part 303 are respectively perpendicularly connected to the terminal switching part 302, and the axes of the external power connection part 301 and the internal power connection part 303 are not collinear.
[0033] The external electrical connection part socket 101 is used to sleeve the external electrical connection part 301, and the end of the external electrical connection part 301 can extend out of the external electrical connection part socket 101 to contact the spring in the external socket to achieve electrical connection.
[0034] The terminal switching part slot 102 is used to embed the terminal switching part 302;
[0035] The internal electrical connection socket 201 is used to fit the internal electrical connection 303, and the end of the internal electrical connection 303 can extend out of the internal electrical connection socket 201 to make contact with the solder pads on the circuit board inside the sensor to achieve electrical connection. This enables the sensor to be connected to an external device through the spring terminal 3, facilitating the external device to obtain the data sensed or collected by the sensor.
[0036] As a specific embodiment of this solution, there are 3 spring terminals 3, and correspondingly, there are 3 receiving cavities; the ends of the 3 external electrical connection parts 301 form an external electrical virtual circle 5; and the ends of the 3 internal electrical connection parts 303 form an internal electrical virtual circle 4.
[0037] In this embodiment, the centers of the external electric virtual circle 5 and the internal electric virtual circle 4 are connected by an axis, but the outer diameters of the external electric virtual circle 5 and the internal electric virtual circle 4 are not equal.
[0038] When the outer diameter of the virtual reed circle formed by the three reeds in the socket of the external device is different from the external virtual circle 5, it means that the sensor cannot be electrically connected to the socket.
[0039] Furthermore, since the core components such as the internal circuit board that constitute the sensor are pre-assembled, the outer diameter of the internal electrical virtual circle 4 remains unchanged. In order for this sensor to be compatible with the virtual spring circle in the above-mentioned socket, the spring terminal 3 structure provided in this embodiment only requires adjusting or replacing the spring terminals with different lengths of the terminal reversing part, and at the same time replacing the new terminal support that can be fitted onto the external electrical connection part and the terminal reversing part of the spring terminal.
[0040] In addition, in this embodiment, the bottom surface of the upper terminal support 1 is provided with a plurality of inserts 105, and the surface of the lower terminal support 2 is provided with insertion holes 204 matching the number of inserts 105. By inserting the inserts 105 into the insertion holes 204, the upper terminal support 1 and the lower terminal support 2 can be quickly connected, thereby limiting and sleeved the spring terminal 3 to form a conductive module.
[0041] It should be noted that in this embodiment, the external electrical connection part 301, the terminal switching part 302, and the internal electrical connection part 303 are all made of the same steel wire, that is, the external electrical connection part 301, the terminal switching part 302, and the internal electrical connection part 303 are all made of steel wire of the same diameter. This structure can ensure that the resistance of each part of the conductor is the same, and the transmission of current or signal is more stable after electrical connection.
[0042] Furthermore, as an optimization of this embodiment, the external electrical connection portion 301 and the internal electrical connection portion 302 have the same specifications.
[0043] Specifically, the external power connection part 301 includes an external power plug part 304 and an external power elastic support part 305 that are connected to each other, and the external power elastic support part 305 is connected to one side of the terminal switching part 302.
[0044] The internal electrical connection part 303 includes an internal electrical plug-in part 307 and an internal electrical elastic support part 308 that are connected to each other. The internal electrical elastic support part 308 is connected to the other side of the terminal switching part 302.
[0045] In this embodiment, the external electrical plug-in part 304 is mainly used to plug into the socket of an external device to achieve electrical connection by contacting the electrical connectors inside the socket, such as springs; the external electrical elastic support part 305 is used to provide flexible contact during the plug-in process to prevent hard damage to the springs inside the external socket.
[0046] The internal electrical connector 307 is mainly used for electrical connection with the pads on the circuit board inside the sensor, and the internal electrical elastic support 308 is used to provide flexible contact during the connection process, so as not to cause hard damage to the circuit board.
[0047] The pitch of the external electrical connector 304 and the internal electrical connector 307 is 0, meaning that the external electrical connector 304 and the internal electrical connector 307 are not elastic, thereby ensuring the stability of the contact during electrical connection; the pitch of the external electrical elastic support 305 and the internal electrical elastic support 308 is greater than 0, meaning that the external electrical elastic support 305 and the internal electrical elastic support 308 are elastic, thereby providing elastic support for the contact between the external electrical connector 304 and the internal electrical connector 307 during electrical connection, avoiding hard damage.
[0048] Furthermore, the outer diameter of the external electrical connector 304 is smaller than the outer diameter of the external electrical elastic support 305, and the outer diameter of the internal electrical connector 307 is smaller than the outer diameter of the internal electrical elastic support 308.
[0049] The length of the external power connector 304 is less than the length of the external power elastic support 305, and the length of the internal power connector 307 is less than the length of the internal power elastic support 308.
[0050] like Figure 3 and Figure 5 As shown, in this embodiment, an external power limiting buffer 306 is also provided between the external power connector 304 and the external power elastic support 305. The external power limiting buffer 306 is in the shape of a helical spring, and its outer diameter gradually decreases from the external power elastic support 305 to the external power connector 304. The external power limiting buffer 306 facilitates better connection of the spring terminal to the terminal support 1 during sensor assembly.
[0051] The external power connection socket 101 includes an external power buffer sleeve 103 for limiting and fitting the external power limiting buffer 306, and an external power support sleeve 104 for fitting the external power elastic support 305. The shape of the external power buffer sleeve 103 matches the external power limiting buffer 306, thereby achieving longitudinal limiting support for the external power connection 301 and ensuring that only the external power plug 304 can extend out of the external power connection socket 101.
[0052] An internal electrical limiting buffer 309 is also provided between the internal electrical plug-in portion 307 and the internal electrical elastic support portion 308. The internal electrical limiting buffer 309 is in the shape of a helical spring, and its outer diameter gradually decreases from the internal electrical elastic support portion 308 to the internal electrical plug-in portion 307. By providing the internal electrical limiting buffer 309, it is convenient that the spring terminal 3 does not need to be aligned internally or externally during assembly. That is, since the external electrical connection portion 301 and the internal electrical connection portion 303 have the same specifications, it is also convenient to install in both directions, thereby improving the assembly efficiency of the sensor. Secondly, it can also be better connected to the terminal lower support 2.
[0053] The internal electrical connection socket 201 includes an internal electrical buffer sleeve 202 that can limit and fit the internal electrical limiting buffer 309, and an internal electrical support sleeve 203 that can fit the internal electrical elastic support 308. The shape of the internal electrical buffer sleeve 202 matches the internal electrical limiting buffer 309, thereby achieving longitudinal limiting support for the internal electrical connection 303 and ensuring that only the internal electrical plug 307 can extend out of the internal electrical connection socket 201.
[0054] It should be noted that, in this embodiment, the pitch of the external electric limiting buffer 306 is smaller than the pitch of the external electric elastic support 305, and the pitch of the internal electric limiting buffer 309 is smaller than the pitch of the internal electric elastic support 308.
[0055] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
