Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of sensor technology, specifically a skeleton positioning structure. Background Technology
[0002] As the core carrier and connecting element for sensor chips, cables, and various functional components, the frame's positioning accuracy and structural stability directly determine the sensor's measurement accuracy, assembly efficiency, and service life. In existing technologies, traditional skeleton structures generally adopt a single-side single-point positioning design, as shown in Figure 1: that is, a single positioning block or positioning hole is set on only one side of the skeleton in the horizontal direction, and positioning is achieved through single-point contact with external tooling. This design has defects in the mainstream assembly scenario where the skeleton is placed vertically: when the skeleton is subjected to gravity, injection pressure or tooling clamping force, the single-point support cannot form a balanced force system, resulting in unstable positioning and easy skewing. Utility Model Content
[0003] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technical solutions are too simplistic. It mainly provides a skeleton positioning structure to solve the technical problems mentioned in the background.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A skeleton positioning structure includes a skeleton body, a chip receiving part for receiving a sensor chip is provided at the end of the skeleton body, and first positioning blocks are staggered on both sides of the skeleton body. The skeleton body has a positioning through hole that penetrates the skeleton body and is used to cooperate with the skeleton connecting piece. Second positioning blocks for positioning are symmetrically installed on both sides of the skeleton body near the skeleton connecting piece.
[0005] Preferably, the first positioning block is a rectangular block structure, and the first positioning block is provided with a positioning groove.
[0006] Preferably, the skeleton connecting piece includes two pieces arranged side by side and a transition connecting piece connecting the ends of the two pieces. The transition connecting piece is provided with a positioning center hole, and the positioning center hole hooks onto the mold positioning post to achieve positioning.
[0007] Preferably, the sheet includes a front end and a rear end, the rear end is provided with a cable riveting part, and the rear ends are connected to each other by a transition connecting piece.
[0008] Preferably, the front end has a circular through groove for use with a positioning through hole.
[0009] Preferably, the second positioning block is a cylindrical structure, and a positioning hole is provided at the center of the outer end of the second positioning block.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The columnar second positioning blocks, symmetrically installed on both sides of the frame body near the frame connecting piece, and the positioning holes at the center of the outer ends of the blocks, provide balanced positioning support, distribute positioning force, and prevent uneven force and skeletal tilting. The positioning holes fit precisely with the external positioning components, which can strictly limit the multi-directional displacement of the frame, reduce positioning errors, and the columnar structure has high mechanical strength, which can protect the frame from external damage and extend the service life of the frame.
[0011] The positioning through-hole of the skeleton body and the circular through-slot at the front end of the skeleton connecting piece are precisely matched to form a rigid positioning system, which avoids the skeleton connecting piece from shifting or loosening during assembly and ensures its relative position to the skeleton body is stable. At the same time, the through-type design improves the connection strength, can resist the external force during the final injection molding, prevents the connecting piece from being misaligned, and facilitates later disassembly and maintenance, reducing the sensor maintenance cost.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0018] Please refer to the appendix carefully. Figure 1-5 A skeleton positioning structure is provided at the end of the skeleton body 1 for receiving a sensor chip. The chip receiving part 2 is tightly integrated with the skeleton body 1 through an integral molding process. The chip receiving part 2 forms a suitable accommodating space at the end of the skeleton body 1 according to the external size, pin arrangement and installation requirements of the sensor chip, ensuring that the chip can be accurately embedded without loose gaps.
[0019] The skeleton body 1 has first positioning blocks 3 staggered on both sides of the horizontal direction. This asymmetrical design can ensure the unique assembly direction of the skeleton body 1 in the mold and prevent the skeleton body 1 from being assembled in the wrong direction. At the same time, when the skeleton body 1 is placed vertically, the staggered first positioning blocks 3 on both sides can limit the skeleton body 1 from different longitudinal heights, effectively resisting the longitudinal tilting tendency of the skeleton body 1 caused by gravity or external pressure. The first positioning block 3 is a rectangular block structure and has a positioning groove 31.
[0020] The skeleton body 1 has a positioning through hole 5 that penetrates the skeleton body 1 and is used in conjunction with the skeleton connecting piece 4.
[0021] The skeleton connecting piece 4 includes two pieces 41 arranged side by side and a transition connecting piece 42 connecting the ends of the two pieces 41. The transition connecting piece 42 is provided with a positioning center hole 421, and the positioning center hole 421 hooks the mold positioning post to achieve positioning. The piece 41 includes a front end 411 and a rear end 412. The rear end 412 is provided with a cable riveting part 413. The cable riveting part 413 used in this utility model is a mature existing technology. Therefore, the components therein will not be described in detail here. The rear ends 412 are connected by the transition connecting piece 42.
[0022] The front end 411 is provided with a circular through groove 414 that works in conjunction with the positioning through hole 5. The inner diameter of the circular through groove 414 is exactly the same as the diameter of the positioning through hole 5, and the axes of the two can be precisely aligned after the skeleton connecting piece 4 and the skeleton body 1 are assembled, forming a continuous through channel. Through precise adaptation with the positioning through hole 5, a collaborative positioning system of through groove, through hole and connector is constructed, which can effectively limit the displacement of skeleton connecting piece 4 in the lateral and longitudinal directions, avoid the offset and loosening problems that are easy to occur in traditional assembly, ensure the stability of the relative position of skeleton connecting piece 4 and skeleton body 1, and provide a reliable foundation for subsequent cable riveting and signal transmission.
[0023] The frame body 1 is symmetrically equipped with second positioning blocks 6 for positioning on both sides of the frame connecting piece 4. The second positioning block 6 is a column structure, and a positioning hole 61 is opened at the center of the outer end of the second positioning block 6.
[0024] The symmetrically arranged cylindrical second positioning blocks 6 provide balanced positioning support from both sides of the skeleton body 1. Compared with traditional single-sided or single-point positioning, this effectively disperses the positioning force, preventing the skeleton from tilting due to uneven force during final injection molding or assembly, and improving the overall positioning stability of the skeleton. The positioning hole 61 at the center of the outer end of the second positioning block 6 can form a precise hole-and-pillar fitting with the external positioning components. This fitting method can strictly limit the displacement of the skeleton in the lateral, longitudinal, and vertical directions, further reducing positioning errors and ensuring the assembly accuracy of components such as the skeleton connecting piece 4 and the chip, laying the foundation for stable sensor operation. The cylindrical structure of the second positioning block 6 has high mechanical strength and is not easily deformed or broken when subjected to mold extrusion or tooling clamping force, effectively protecting the skeleton body 1 from external damage and extending the service life of the skeleton.
[0025] The specific operation process of this utility is as follows: When using the skeleton positioning structure to assemble the sensor, firstly, the skeleton body 1 and the sensor chip are assembled. The sensor chip is precisely embedded into the chip receiving part 2 integrally formed at the end of the skeleton body 1. The fitting space of the chip receiving part 2 is used to ensure that the chip has no loose gaps, thus completing the initial fixation of the chip.
[0026] After the core components are assembled, the skeleton is positioned and installed as a whole. The positioning grooves 31 on the first positioning blocks 3, which are staggered on both sides of the skeleton body 1, are fitted with the corresponding clips of the assembly tooling. The staggered layout limits the skeleton from different longitudinal heights to prevent it from tilting longitudinally. At the same time, the positioning holes 61 at the outer ends of the second positioning blocks 6, which are symmetrically positioned on the side of the skeleton body 1 near the skeleton connecting piece 4, are fitted into the mold positioning post. The positioning center hole 421 on the transition connecting piece 42 hooks onto another mold positioning post, forming a multi-dimensional positioning system to ensure that the skeleton does not have any lateral, longitudinal, or vertical displacement during the final injection molding process.
[0027] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
