Description

Technical Field

[0001] This utility model belongs to the field of contact technology, specifically relating to a ring-shaped temperature compensation contact. Background Technology

[0002] Temperature compensation contacts are commonly used in aero engines to measure engine temperature. Currently, commonly used temperature compensation contacts are made of nickel-chromium-nickel-silicon materials. There are two types of sockets: one is a standard open hole, and the other is a slotted spring sleeve structure.

[0003] Current temperature compensation contacts consist of pins and sockets. When the socket is an open hole, due to the poor elastic strength of the nickel-chromium and nickel-silicon materials, the traditional closed-end design of the socket is prone to plastic deformation under high vibration conditions, resulting in insufficient socket force and weak hole strength, leading to momentary signal interruption. When a slotted spring sleeve structure is used, the poor elastic strength of the socket material can be compensated for, providing continuous positive pressure to the socket and resisting high vibration. However, during use and removal, the fixing claw is prone to getting stuck in the slot of the sleeve, making it difficult to remove. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a ring-shaped temperature compensation contact, which features a slotted groove on one side of the contact hole, enabling the contact hole to deform radially and open when the adapter pin is inserted. Additionally, a ring plate is fitted around the outer periphery of the contact hole, providing a force to maintain contact between the contact hole and the pin.

[0005] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a ring-shaped temperature compensation contact includes an axially extending insertion hole 3. A slot 34 is provided on one side of the contact hole 31 at the front end of the insertion hole 3 for insertion with an adapter pin. The slot 34 extends axially along the insertion hole 3 and connects the inside and outside of the contact hole 31. An annular groove 311 is provided on the outer periphery of the front end of the contact hole 31. A ring piece 2, positioned and assembled within the annular groove 311, provides the contact hole 31 with an elastic force to clamp the adapter pin. When the adapter pin is inserted, the contact hole 31 is opened, causing the ring piece 2 to expand radially, providing the contact hole 31 with a force to radially hold the pin.

[0006] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0007] The aforementioned ring-shaped temperature compensation contact also has a protective sleeve 1 on the outer periphery of the front end of the socket 3 for protecting the contact hole 31. The protective sleeve 1 can provide external protection for the contact hole at the front end of the socket 3.

[0008] The aforementioned ring-shaped temperature compensation contact has an opening 21 on one side of the ring 2 that extends through the axial direction of the ring 2. The opening 21 enables the ring 2 to have radial expansion and contraction capabilities, thereby providing radial extrusion force to the contact hole when the contact hole is opened.

[0009] In the aforementioned ring-shaped temperature compensation contact, the opening 21 is V-shaped. The bottom of the V-shaped opening is located in the middle of the ring plate 2 in the axial direction, and the inclined portions on both sides of the bottom extend towards the front and rear end faces of the ring plate 2, respectively. The setting of the V-shaped opening enables the ring plate to have reliable and stable radial expansion and contraction capabilities.

[0010] In the aforementioned annular temperature compensation contact, the bottom of the opening 21 is arc-shaped.

[0011] In the aforementioned ring-shaped temperature compensation contact, the ring plate 2 is a closed ring structure extending axially along the insertion hole 3, and the closed ring structure has the ability to undergo radial elastic deformation.

[0012] In the aforementioned ring-shaped temperature compensation contact, there are at least two ring pieces 2, which are distributed axially in the ring groove 311. At this time, the contact hole has at least two force points, which can ensure stable contact between the pin and the hole, improve mechanical life and high vibration resistance.

[0013] In the aforementioned annular temperature compensation contact, the contact hole 31 has at least two slots 34 distributed circumferentially to improve the radial deformation capability of the contact hole.

[0014] In the aforementioned annular temperature compensation contact, the extension length of the slot 34 along the axial direction of the insertion hole 3 is greater than the axial length of the contact hole 31.

[0015] The aforementioned ring-shaped temperature compensation contact has a guide structure at the front end of the sheath 1 and the front end of the contact hole 31 for guiding the adapter pin into the contact hole, so that the pin enters the contact hole under two-stage guidance, ensuring the docking accuracy of the pin and the hole.

[0016] Compared with the prior art, this utility model has significant advantages and beneficial effects. Through the above technical solution, this utility model achieves considerable technological advancement and practicality, and has broad industrial application value. It possesses at least the following advantages:

[0017] The socket of this utility model has a slot on one side to give it radial deformation capability, which can be opened when the fitting pin is inserted. At the same time, a ring plate is wrapped around the socket to provide radial holding force for the socket, thereby ensuring reliable contact between the pin and the socket.

[0018] This invention provides two axially distributed rings around the socket, giving the socket two force points, thereby ensuring stable contact between the pin and the socket, improving mechanical life and high vibration resistance.

[0019] The ring plate of this utility model is a ring structure with a "V" shaped groove on one side. The "V" shaped groove makes the ring plate have a stable and reliable deformation capability, and can provide a stable and reliable positive pressure for the socket. Attached Figure Description

[0036] To further illustrate the technical means and effects adopted by this utility model to achieve the intended purpose of the invention, the following detailed description of the specific implementation method, structure, features and effects of the ring-shaped temperature compensation contact element proposed according to this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0037] Please see Figure 1-3This is a schematic diagram of the various parts of the ring-shaped temperature compensation contact of this utility model. The temperature compensation contact includes an axially extending insertion hole 3. The front end of the insertion hole 3 has a contact hole 31 for inserting an adapter pin, and the rear end has a wiring hole 32 for connecting to a wire. Preferably, a radially extending through hole 33 is also provided on one side of the wiring hole 32. The through hole 33 is located near the front end of the wiring hole 32, and adhesive can be injected into the wiring hole 32 through the through hole 33 to fix the wire in the wiring hole 32. In other embodiments of this utility model, the wiring hole 32 may also be a crimping hole structure for crimping with a wire or a welding hole structure for welding and fixing with a wire.

[0038] A slot 34 is formed on one side of the front end of the socket 3, penetrating both the inside and outside of the socket 3. The slot 34 extends axially backward from the front end face of the socket 3, making the contact hole 31 at the front end of the socket 3 open and capable of radial deformation. The length of the slot 34 extending axially along the socket 3 is not less than the axial length of the contact hole 31. In this embodiment, the length of the slot 34 is greater than the axial length of the contact hole 31, so that one side of the socket 3 has an opening extending through its length.

[0039] The contact hole 31 has an annular groove 311 on its outer periphery at the front end. An annular piece 2 is disposed within this groove 311. The annular piece 2 provides positive pressure (radial contact force) to the contact hole 31 when it engages with the adapter pin. The side walls of the annular groove 311 axially limit the movement of the annular piece 2. When the adapter pin is inserted into the contact hole 31, the contact hole 311 is expanded during insertion, radially expanding under the action of the side groove 34, allowing the pin to enter the contact hole 31. Simultaneously, the annular piece 2 fits around the outer periphery of the contact hole 31, providing a radial contraction force to the contact hole 31, ensuring good contact between the contact hole 31 and the adapter pin. The annular piece 2 of this invention has radial elastic deformation capability, expanding with the radial expansion of the contact hole 31 and providing a radial contraction force to the contact hole 31 in the expanded state.

[0040] In this embodiment of the invention, the ring piece 2 has an annular structure with an opening 21 on one side and extending axially along the insertion hole 3. Preferably, the opening 21 on one side of the ring piece 2 is V-shaped. The V-shaped opening 21 is composed of two inclined openings extending from both ends of the ring piece 2 towards the middle. That is, both sides of the opening 21 of the ring piece 2 form V-shaped end faces, one of which is a V-shaped groove 22, and the other is a corresponding V-shaped protrusion 23. The bottom of the V-shaped groove is located in the middle of the axial extension of the ring piece 2, while the two groove walls extend towards the front and rear end faces of the ring piece 2, respectively. Preferably, the bottom of the V-shaped groove and the top of the V-shaped protrusion are both arc-shaped. In this embodiment, the ring piece 2 is made of stainless steel, but in other embodiments, the ring piece 2 may also be made of other materials with good elastic strength.

[0041] In other embodiments of this utility model, the ring plate 2 is also a closed ring structure made of elastic material. In this case, when the contact hole 31 of the ring plate 2 expands outward, it expands elastically and provides elastic pressure to the contact hole 31.

[0042] In this embodiment of the invention, there are two ring pieces 2, which are arranged axially back and forth along the annular groove 311, so that the contact hole 31 has two force-bearing points, realizing the product redundancy design, ensuring stable contact between the pin and the socket, and improving mechanical life and high vibration resistance. In this embodiment, the two ring pieces 2 are axially connected back and forth, with the tail end face of the first ring piece 2 connected to the front end face of the second ring piece 2, while the other two end faces of the two ring pieces 2 are axially stopped and limited by the inner wall of the annular groove 311. In other embodiments of the invention, the sum of the axial dimensions of the two ring pieces 2 is slightly smaller than the axial dimension of the annular groove 311.

[0043] In this embodiment of the invention, the front and rear walls of the annular groove 311 are both arc-shaped, but in other embodiments, the walls of the annular groove 311 may also be vertical.

[0044] In this embodiment of the present invention, there is only one split groove 34, but in other embodiments of the present invention, two or more split grooves 34 may be provided, which are evenly distributed around the insertion hole 3.

[0045] In this embodiment of the present invention, there are two ring pieces 2. However, in other embodiments of the present invention, there may be only one ring piece 2, or more than two ring pieces 2. In this case, multiple ring pieces 2 are axially connected and distributed in the ring groove 311 to increase the force points of the contact hole 31, ensure the contact stability between the pin and the hole, and further improve the mechanical life and high vibration resistance.

[0046] A protective sleeve 1 is also provided on the outer periphery of the front end of the insertion hole 3, which is used to provide external protection for the insertion hole 3. The protective sleeve 1 is fixedly installed on the outer periphery of the front end of the insertion hole 3, and the fixing method can be forced installation. A ring platform 35 is provided on the outer periphery of the insertion hole 3, and the front end of the ring platform 35 faces the tail end face of the protective sleeve 1 for axial limitation. The axial extension length of the protective sleeve 1 is greater than the axial extension length of the contact hole 31. The front end of the insertion hole 3 is located inside the protective sleeve 1, and the front end of the protective sleeve 1 is also provided with a guide structure 11 for guiding the adapter end pin to enter. In this embodiment, the guide structure 11 is a guide slope formed by folding the front end of the protective sleeve 1 inward.

[0047] The contact hole 31 of the socket 3 has a guide opening 312 at its front end for guiding the pin into the socket. In this embodiment, the guide opening 312 is a tapered guide opening that gradually narrows from front to back. When the contact member of this utility model is inserted with the adapter pin contact member, the guide structure 11 at the front end of the sheath 1 forms a primary guide for the pin, while the guide opening 312 forms a secondary guide for the pin. The two-stage guide structure enables precise insertion of the pin and the socket.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
