Description

Technical Field

[0001] This utility model relates to the field of sensor equipment technology, and in particular to sensor terminals. Background Technology

[0002] For common three-prong terminal sensors, their corresponding internal chips also have three prongs. However, since the female connector on the vehicle is already defined, there may be situations where the pin definitions are different from those of the chip. In this case, it is necessary to change the structural layout of the terminals to connect with the chip pins in order to achieve the purpose of power supply to power supply, ground to ground, and output to output.

[0003] like Figure 1 As shown, in the prior art, the terminal pins are generally interchanged through spatial layout, which is relatively complex and requires multiple bends to meet the size requirements. Therefore, terminal forming is difficult, and a lot of waste is generated during the processing, resulting in high forming costs. Utility Model Content

[0004] This application provides a sensor terminal with a simpler structural design, easier size control, easier stamping and forming, and facilitates ensuring the quality of the sensor terminal. It also results in less waste after stamping and lower forming costs.

[0005] This application provides a sensor terminal for matching a predefined chip, wherein the chip has a power lead, a ground lead, and an output terminal. The sensor terminal includes a ground terminal, an output terminal, and a power terminal that are arranged in parallel and spaced apart in the same horizontal direction. The sensor terminal has a predetermined extension direction, and a female connection terminal and a chip connection terminal are formed at both ends of the extension direction, respectively.

[0006] At the chip connection end, the power terminal is U-shaped and surrounds the ground terminal and the output terminal in a gap fit. The U-shaped power terminal is defined as including a body, an adapter, and an external connection part connected in sequence. The body extends to the female connection end. The portion of the ground terminal and the output terminal that corresponds to the external connection part in the vertical direction of the extension direction is defined as the connection part. The connection part and the external connection part have the same height, and the same height is higher than the height of the body part and the adapter part, so as to be able to connect the ground lead, the output terminal, and the power lead.

[0007] In one possible implementation, the connecting portion connects the body portion of the ground terminal and the output terminal via a bending portion, the longitudinal cross-section of the external connecting portion is trapezoidal, and the upper bottom of the external connecting portion is at the same height as the top of the connecting portion.

[0008] In one possible implementation, the main body and the connecting part are located at the same height, and the spatial difference between the top of the external connecting part and the top of the connecting part is 0.6-1 times the thickness of the main body.

[0009] In one possible implementation, two arc-shaped notches are symmetrically provided on the inner sidewall near the center between the ground terminal and the output terminal, and between the output terminal and the power terminal, and a predetermined gap is provided between the two arc-shaped notches in the extending direction, so as to connect the ground terminal and the output terminal, and the output terminal and the power terminal at the predetermined gap during injection molding.

[0010] Beneficial effects: Compared with the prior art, the sensor terminal structure provided by this application is simpler, more stable, easier to control in terms of processing size, can be well matched with predefined chips, and is less prone to short circuits between different terminals. It also produces less waste after stamping and has lower molding costs.

[0011] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0017] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] refer to Figures 1 to 4 This application provides a sensor terminal for matching a predefined chip 10, wherein the chip 10 has a power lead 11, a ground lead 12, and an output terminal 13. The sensor terminal 20 includes a ground terminal 21, an output terminal 22, and a power terminal 23 arranged in parallel and spaced apart in the same horizontal direction. The sensor terminal 20 also has a predetermined extension direction, and a female connection terminal 201 and a chip connection terminal 202 are formed at both ends of the extension direction, respectively, for connecting the sensor housing part and the chip 10.

[0020] Furthermore, at the chip connection terminal 202, the power terminal 23 is U-shaped and surrounds the ground terminal 21 and the output terminal 22 in a gap-fit ​​manner. The power terminal 23, defined as U-shaped, includes a body portion 231, an adapter portion 232, and an external connection portion 233 connected in sequence. The body portion 231 extends to the female connection end 201. The portion of the ground terminal 21 and the output terminal 22 corresponding to the external connection portion 233 in the vertical direction of the extension direction is defined as a connection portion 211. The connection portion 211 and the external connection portion 233 maintain the same height, and the same height is higher than the height of the body portion 231 and the adapter portion 232, so that the ground lead-out end 12, the output end 13, and the power lead-out end 11 can be connected accordingly. At the same time, the height difference design makes it less likely for short circuits to occur between the ground terminal 21, the output terminal 22, and the power terminal 23. Therefore, the sensor terminal structure provided by this application is simpler and more stable. It is not only easy to stamp and form, but also easy to control the size, which facilitates ensuring the forming quality of the sensor terminal 20. In addition, there is less waste after stamping, and the forming cost is low.

[0021] In one embodiment, the connecting portion 211 connects the ground terminal 21 and the body portion of the output terminal 22 through the bending portion 212. Meanwhile, the longitudinal cross-section of the external connecting portion 233 is trapezoidal, and the upper bottom of the external connecting portion 233 is at the same height as the top of the connecting portion 211. This bending forming process is easy to implement.

[0022] In one embodiment, the main body 231 and the adapter 232 are located at the same height, and the spatial difference between the top of the external connection 233 and the top of the adapter 232 is 0.6-1 times the thickness of the main body 231. This ensures that short circuits are less likely to occur between the ground terminal 21, the output terminal 22 and the power terminal 23, while also not occupying a large installation space.

[0023] During the injection molding process, to ensure the relative dimensions of the ground terminal 21, output terminal 22, and power terminal 23, it is easy to cause dimensional defects if they are injection molded one by one. Therefore, a bracket is first injection molded from a single piece of plate to ensure the stability of the relative dimensions, and then the connecting parts are punched off. However, directly punching off the connecting parts can easily produce burrs at the punching notch, which can easily cause short circuits. Therefore, on the inner sidewall near the middle of the ground terminal 21 and the output terminal 22, and the output terminal 22 and the power terminal 23, the connecting parts are... Two symmetrical arc-shaped notches 203 are provided, and a predetermined gap is provided between the two arc-shaped notches 203 located in the extending direction, so that the ground terminal 21 and the output terminal 22 are connected at the predetermined gap during injection molding, and the output terminal 22 and the power terminal 23 are connected. In this way, while ensuring relative dimensional stability, the arc-shaped notches 203 can ensure that short circuits are not likely to occur between the ground terminal 21, the output terminal 22 and the power terminal 23 of the sensor terminal 20, thereby ensuring the quality of the sensor terminal 20.

[0024] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
