Description

Technical Field

[0001] This invention belongs to the field of temperature sensor technology, and in particular to a shockproof and collision-resistant NTC temperature sensor. Background Technology

[0002] NTC temperature sensors are thermistors or probes whose principle is that the resistance value decreases rapidly as the temperature rises. They are usually composed of two or three metal oxides mixed in a fluid-like clay and sintered in a high-temperature furnace to form a dense sintered ceramic. The actual size is very flexible. In the field of temperature measurement and control, negative temperature coefficient (NTC) thermistor sensors are widely used in many fields such as consumer electronics, home appliances, automotive electronics, medical equipment, and industrial monitoring due to their advantages such as high sensitivity, fast response speed, and relatively low cost.

[0003] During the production, warehousing, and logistics of products, especially in scenarios involving large-volume, high-density transportation, NTC temperature sensors are often densely stacked in turnover boxes, packaging bags, or pallets in bulk or simple inner packaging. In this state, there is a lack of effective isolation and buffering between individual sensors. During long-distance transportation, loading and unloading, handling, and even vehicle travel, the packaging containers will inevitably be subjected to continuous or intermittent shaking, vibration, collision, and impact. This mechanical movement will cause the stacked sensors to undergo relative displacement and mutual collision, which can easily lead to cracking of the electrode solder joints, thereby affecting the normal use of the NTC temperature sensor.

[0004] The purpose of this invention is to provide a shockproof and collision-resistant NTC temperature sensor to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a shockproof and collision-resistant NTC temperature sensor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shockproof and collision-resistant NTC temperature sensor, including a connector, a wire connected to the outside of the connector, an electrode disposed on the top of the wire, a protective sleeve disposed on the outside of the electrode, a plurality of sliding parts disposed inside the protective sleeve, the sliding parts being in close contact with the outside of the wire, the protective sleeve moving synchronously with the sliding parts moving when it moves outside the wire, mounting plates symmetrically disposed on the outside of the protective sleeve, a locking part disposed between two mounting plates, rotating the locking part to fix the protective sleeve on the outside of the electrode.

[0007] Furthermore, the sliding part includes several connecting plates symmetrically arranged inside the protective sleeve, and a roller connected by a rotating shaft is provided between two of the connecting plates.

[0008] Furthermore, a sliding groove is provided on one side of each of the connecting plates, and a sliding block is slidably connected in the sliding groove. A second spring is provided on one side of the sliding block, the end of the second spring is connected to the inside of the sliding groove, and the sliding block is connected to the rotating shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, by setting up components such as a protective sleeve and a locking part, allows the protective sleeve to be moved to the outside of the electrode during transportation, and then locked by rotating the rotating rod.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] Please see Figures 1 to 5 As shown, a shockproof and collision-resistant NTC temperature sensor includes a connector 1, a wire 2 connected to the outside of the connector 1, an electrode 4 disposed on the top of the wire 2, and a protective cloth 6 disposed on the top of the protective sleeve 3. The protective cloth 6 is a dustproof cloth with a certain degree of elasticity.

[0027] A protective sleeve 3 is provided on the outside of the electrode 4. Several sliding parts are provided inside the protective sleeve 3. The sliding parts are in close contact with the outside of the wire 2. The sliding parts are moved synchronously by the displacement of the protective sleeve 3 on the outside of the wire 2. The sliding parts include several connecting plates 14 symmetrically arranged inside the protective sleeve 3. A roller 15 connected by a rotating shaft is provided between two connecting plates 14. A sliding groove 16 is opened on one side of a single connecting plate 14. A sliding block 17 is slidably connected in the sliding groove 16. A second spring 18 is provided on one side of the sliding block 17. The end of the second spring 18 is connected to the inside of the sliding groove 16, and the sliding block 17 is connected to the rotating shaft.

[0028] The deformation of the second spring 18 pushes the sliding block 17 to drive the roller 15 connected to the rotating shaft to fit tightly against the outside of the wire 2. The second spring 18 can protect the roller 15 from damage to the wire 2, and at the same time facilitate the movement of the protective sleeve 3 on the outside of the wire 2.

[0029] The protective sleeve 3 is symmetrically provided with mounting plates 5 on its outer side. A locking part is provided between the two mounting plates 5. Rotating the locking part completes the action of fixing the protective sleeve 3 on the outside of the electrode 4. The locking part includes a cam 8 rotatably connected between the mounting plates 5. A rotating rod 7 is provided on one side of the cam 8. A mounting plate 9 is provided inside the mounting plate 5. A contact block 10 is provided on one side of the mounting plate 9. A first spring 11 is provided on the other side. The end of the first spring 11 is connected to the protective sleeve 3. A connecting post 12 is provided on one side of the mounting plate 9. The first spring 11 is sleeved on the outside of the connecting post 12. The connecting post 12 extends into the protective sleeve 3 and its end is connected to a fixing plate 13.

[0030] Rotating the rotating rod 7 causes the cam 8 to rotate, which in turn moves the contact block 10, which in turn pushes the connecting column 12 to slide inside the protective sleeve 3, thereby moving the fixing plate 13. This ensures that the wire 2 is tightly attached to the inner wall of the protective sleeve 3, thus ensuring the stability of the protective sleeve 3 and protecting the electrode 4 from shaking and collision, which could cause damage.

[0031] Working principle: When in use, rotate the rotating rod 7 to release the limit on the protective sleeve 3, so that it can move outside the wire 2. During the movement, the roller 15 rotates, thereby driving the sliding block 17 connected to the roller 15 to slide in the sliding groove 16, thereby compressing the second spring 18. When the protective sleeve 3 wraps the electrode 4 on the outside of the electrode 4, the protective cloth 6 restores the front opening of the protective sleeve 3.

[0032] Then, rotate the rotating rod 7 again. The rotating rod 7 rotates within the mounting plate 5, thereby driving the cam 8 to rotate. This causes the protruding part of the protrusion to contact the contact block 10, thereby pushing it. This causes the mounting plate 9 connected to the contact block 10 to move, thereby causing the connecting post 12 to slide within the protective sleeve 3. This compresses the first spring 11, causing the connecting post 12 to push the fixing plate 13 to move, fixing the wire 2 within the protective sleeve 3. This maintains the stability of the protective sleeve 3, thus protecting it and preventing damage during transportation.
