Technical Field

[0001] This utility model relates to the field of pressure sensor application technology, and in particular to a retainer for a pressure sensor. Background Technology

[0002] A pressure sensor is a device that converts pressure (force acting on a unit area) into a measurable electrical signal. It is an indispensable key component in fields such as industrial automation, process control, automotive, medical, aerospace, and consumer electronics.

[0003] In existing pressure sensors, the female connector extending from the internal circuit board is usually directly exposed to the outside. When connected to the male connector, it will wobble, which will pull on the internal wiring harness and cause sliding wear on the outer wall of the wiring harness, increasing the later maintenance cost. Therefore, this utility model proposes a retainer for pressure sensors. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a retainer for a pressure sensor. By installing the retainer inside the pressure sensor, the external connector can be fixed, thereby preventing the connector from shaking and causing wear to the wiring harness, and at the same time avoiding the exposed connector from pulling and damaging the internal wiring harness during use.

[0005] To solve the above-mentioned technical problems, the present invention provides a holder for a pressure sensor, including a frame body, wherein the frame body is cylindrical in shape and made of polytetrafluoroethylene, and the outer wall of the frame body is symmetrically provided with sliding grooves;

[0006] The frame has a through-hole groove, which is rectangular in shape. The bottom of the groove has a first-level ladder groove, and the middle of the first-level ladder groove has a second-level ladder groove.

[0007] The top of the limiting groove is provided with a slot B from one end of the frame to the other end, and the slot B is connected to the limiting groove.

[0008] The present invention is further configured such that both of the slides are U-shaped, and their bottom corners are curved, while the top of the side wall and the outer wall of the frame are curved transitions.

[0009] The above technical solution facilitates the stable sliding of the device into the pressure sensor using the grooves on both sides, and allows for proper positioning and installation.

[0010] The present invention is further configured such that: the bottom two corners of the limiting groove are both arc-shaped, and the connection between the limiting groove, the first-level ladder groove and the second-level ladder groove is arc-shaped bend.

[0011] By utilizing the above technical solution and the arc-shaped design at multiple bends and connections, the frame can adapt to deformation under pressure during installation, thus protecting the entire frame.

[0012] The present invention is further configured such that: the secondary ladder groove is provided with a slot A from one end of the frame to the other end, and slot A and slot B are arranged opposite to each other, while the two sliding grooves are arranged alternately with slot A and slot B.

[0013] Through the above technical solution, slot A can be used in conjunction with slot B to enable the frame to adapt to compression and adjustment during installation, thereby using its elasticity to stably fix it inside the pressure sensor.

[0014] The present invention is further configured such that slots are symmetrically provided at the middle positions of the two side walls of the slot A, and the slots are arranged in a V-shape.

[0015] The above technical solution utilizes a V-shaped slot to engage and secure the inserted female plug at the corresponding position.

[0016] The present invention is further configured such that the width of the slot B on one side of the limiting slot is greater than the width on one side of the frame, and the connection between the slot B and the inner wall of the limiting slot and the outer wall of the frame are both arc-shaped.

[0017] Through the above technical solution, the slot B allows the frame to undergo a certain amount of plastic deformation during the installation process, so that the frame has a certain tension in the pressure sensor, thereby ensuring its firmness inside the frame.

[0018] The present invention is further configured such that: slots are symmetrically provided at the middle of the two side walls of the slot B, and the slots are V-shaped as a whole, while one side wall is arc-shaped.

[0019] The above technical solution facilitates the use of slots to fix the position of the female plug on the wire harness, and the slots are used to lock and fix it in the corresponding position, ensuring its stability during use.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. The pressure sensor retainer proposed in this utility model can fix the external connector by installing the retainer inside the pressure sensor, thereby preventing the connector from shaking and causing wear to the wiring harness;

[0022] 2. The pressure sensor retainer proposed in this utility model can prevent the exposed connector from pulling and damaging the internal connecting wire harness during use. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, a retainer for a pressure sensor includes a frame 1, which is cylindrical in shape and made of polytetrafluoroethylene. The outer wall of the frame 1 has symmetrically formed sliding grooves 11, both of which are U-shaped and have arc-shaped bends at their bottom corners. The top of the side wall and the outer wall of the frame 1 are also arc-shaped transitions, which facilitates the stable sliding of the sliding grooves 11 on both sides into the interior of the pressure sensor and for positioning and installation.

[0030] like Figures 2-4As shown, a limiting groove 12 is formed through the interior of the frame 1, and the limiting groove 12 is rectangular in shape. The bottom corners of the limiting groove 12 are curved. The connections between the limiting groove 12, the first-stage ladder groove 13, and the second-stage ladder groove 14 are all curved bends. The curved design of these multiple bends allows the frame 1 to adapt to deformation under pressure during installation, thus protecting the entire frame. A first-stage ladder groove 13 is formed at the bottom of the limiting groove 12, and a second-stage ladder groove 14 is formed in the middle of the first-stage ladder groove 13. The second-stage ladder groove 14 extends from the frame 1... A slot A141 is provided from one end to the other, and slot A141 and slot B15 are arranged opposite each other. At the same time, two sliding grooves 11 are arranged alternately with slot A141 and slot B15. Slot A141 can cooperate with slot B15 to realize the adaptation and compression adjustment of the frame 1 during installation, so as to fix it in the pressure sensor with elasticity and stability. Slots 142 are symmetrically provided in the middle of the two side walls of slot A141, and slots 142 are arranged in a V shape. The V-shaped slots 142 can be used to lock and fix the inserted female plug in the corresponding position.

[0031] like Figure 2 and Figure 4 As shown, a slot B15 is provided on the top of the limiting groove 12 from one end of the frame 1 to the other end, and the slot B15 is connected to the limiting groove 12. The width of the slot B15 on one side of the limiting groove 12 is greater than the width on one side of the frame 1, and the connection between the slot B15 and the inner wall of the limiting groove 12 and the outer wall of the frame 1 is arc-shaped. The slot B15 allows the frame 1 to undergo a certain plastic deformation during the installation process, so that the frame 1 has a certain tension in the pressure sensor, thereby ensuring its firmness inside the frame 1. The two side walls of the slot B15 are symmetrically provided with slots 151 in the middle, and the slots 151 are V-shaped as a whole. At the same time, one side wall is arc-shaped, which makes it easy to fix the position of the female plug on the wire harness using the slots 151, and to use the slots 151 to lock and fix it in the corresponding position, ensuring its stability in use.

[0032] In use, this utility model utilizes the sliding grooves 11 on both sides of the frame 1 to install it inside the pressure sensor, and uses the internal limiting groove 12, primary ladder groove 13 and secondary ladder groove 14 to fix the female plug, thereby enabling it to be stably installed inside the pressure sensor and ensuring that it will not fall off or shake during use, thus preventing it from affecting the internal wiring harness.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
