Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor. Background Art

[0002] With the strengthening of environmental awareness, various electrical equipment such as automobiles and electrical appliances are increasingly powered by new energy battery packs. Since new energy battery packs generate heat during charging and power supply, the heat generation poses certain safety hazards to the normal use of new energy battery packs. If the heat generation is severe, it may cause electrical equipment to heat up, short-circuit or even spontaneously combust, seriously affecting property and personal safety. The temperature sensor installed on the battery pack can be used to monitor the operating temperature of the battery pack in real time, thereby ensuring the safe operation of the battery pack and extending its service life. Therefore, a temperature sensor for energy storage batteries is required. China has authorized a utility model patent (publication number: CN219714577U) to propose a sensor for monitoring the temperature of a battery. The device can make the sensor device more stable when monitoring the internal installation of the battery by setting a shock-absorbing mechanism. The sensor will not produce large vibrations during the temperature measurement process, which enhances the accuracy of temperature sensor monitoring.

[0003] However, the above device has some shortcomings when in use: the vibration reduction mechanism is directly fixed on the surface of the sensor. Although this connection method can reduce vibration to a certain extent, it also brings some problems. First, the fixed connection method makes it difficult to disassemble the sensor and the vibration reduction mechanism. Once the sensor is damaged, the entire assembly, including the vibration reduction mechanism, needs to be replaced, which undoubtedly increases the maintenance cost. Therefore, a sensor is proposed to address the above situation. Utility Model Content

[0004] The purpose of the utility model is to solve the disadvantage that the fixed connection mode in the prior art makes it difficult to disassemble the sensor and the vibration reduction mechanism. Once the sensor is damaged, the entire assembly, including the vibration reduction mechanism, needs to be replaced, which undoubtedly increases the maintenance cost.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sensor comprises a temperature sensor body. A protective sleeve is arranged outside the temperature sensor body. The protective sleeve is provided with a mounting groove. The protective sleeve is provided with two groups of card interfaces in a ring array. The two groups of card interfaces are provided with a plurality of protective components.

[0007] The protection component comprises a mounting plate, a pair of card blocks are arranged on one side of the mounting plate close to the protection sleeve, the pair of card blocks are both matched with the card interface, and vibration damping pads are arranged on the corresponding two sides of the mounting plate.

[0008] The protective sleeve is also provided with an annular groove, and the top surface and the bottom surface of the annular groove are both provided with limiting blocks in an annular array.

[0009] Preferably, the interior of the protective sleeve is a hollow structure, the bottom of the protective sleeve is open, and a pair of rectangular through holes are formed at the top of the protective sleeve.

[0010] Preferably, a heat dissipation window is provided in a ring shape on the surface of the mounting groove, and each heat dissipation window is provided with a plurality of heat dissipation holes connected to the protective sleeve.

[0011] Preferably, the limiting block is arc-shaped and is made of rubber material.

[0012] Preferably, the number of card interfaces in each group is twelve, and each protective component cooperates with two card interfaces.

[0013] Preferably, the vibration-damping pad close to one side of the mounting groove contacts the mounting groove, and the vibration-damping pad is made of a silicone material.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model places the protective component on the protective cover through the structural design of the installation slot, the card interface and the protective component, which can not only better absorb and disperse the vibration and impact from the external environment, but also protect the temperature sensor body. At the same time, when the temperature sensor body is damaged, only a new temperature sensor body needs to be replaced without replacing the vibration reduction mechanism at the same time, which not only simplifies the maintenance process, but also greatly reduces the maintenance cost. In addition, since the vibration reduction mechanism can be reused, the overall production cost is further reduced and the economic benefit is improved.

[0016] 2. The utility model adopts the structural design of the annular groove and the limit block. When using the device, the excessively long wires of the temperature sensor body can be conveniently wound in the annular groove and limited by the limit block, which can effectively avoid the problem of disordered wires. The neat wire layout also helps to reduce the risk of damage to the temperature sensor body due to entanglement or pulling of the wires. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A sensor includes a temperature sensor body 1, a protective sleeve 2 is arranged on the outside of the temperature sensor body 1, the interior of the protective sleeve 2 is a hollow structure, the bottom of the protective sleeve 2 is open, and a pair of rectangular through holes are arranged on the top of the protective sleeve 2, and a mounting groove 201 is arranged on the protective sleeve 2, and a heat dissipation window 2010 is arranged in a ring shape on the surface of the mounting groove 201, and each heat dissipation window 2010 is provided with a plurality of heat dissipation holes connected to the protective sleeve 2. Furthermore, by providing the heat dissipation windows 2010, the heat dissipation performance of the temperature sensor body 1 can be better guaranteed, which helps to reduce the heat generated by the temperature sensor body 1 during operation, prolong its service life, and improve its measurement accuracy and stability. Two groups of card interfaces 202 are arranged in a ring array on the protective sleeve 2, and the number of each group of card interfaces 202 is twelve. Several protective components 3 are arranged on the two groups of card interfaces 202, and each protective component 3 cooperates with two card interfaces 202.

[0024] The protective component 3 includes a mounting plate 301, and a pair of card blocks 302 are arranged on the side of the mounting plate 301 close to the protective sleeve 2. The pair of card blocks 302 cooperate with the card interface 202, and vibration-damping pads 303 are respectively arranged on the corresponding two sides of the mounting plate 301. The vibration-damping pad 303 close to the side of the mounting groove 201 is in contact with the mounting groove 201. The vibration-damping pad 303 is made of silicone material. Furthermore, through the design of the double-layer vibration-damping pad 303, the vibration-damping effect can be improved. At the same time, the external vibration-damping pad 303 can also protect the protective sleeve 2 to avoid the protective sleeve 2 from being broken or damaged due to accidental bumps.

[0025] An annular groove 4 is also provided on the protective sleeve 2. The top and bottom surfaces of the annular groove 4 are both provided with limit blocks 401 in an annular array. The limit blocks 401 are arc-shaped and are made of rubber material. When in use, the staff can wind the excessively long wire in the annular groove 4 and limit it by the limit blocks 401. The limit blocks 401 are made of rubber material and have a certain deformation ability. The wire can be inserted into the annular groove 4 through the gap between the two limit blocks 401, which effectively avoids the problem of disordered wires. The neat wire layout also helps to reduce the risk of damage to the temperature sensor body 1 due to wire entanglement or pulling.
