Background

The compressor is generally used as a refrigeration compressor, for example, as an outdoor unit of an air conditioner, and the compressor operates by extracting and compressing refrigerant from a low-pressure region, sending the refrigerant to a high-pressure region for cooling and condensing, and then radiating heat to the air through a heat radiating fin, thereby performing a temperature regulation function. Through the operating mode temperature of each main part of control air conditioner, the operating parameter of each part can be adjusted more intelligently to air conditioner control system to play the effect that promotes energy-conserving increase, and can avoid the work part overheated and lead to working life to descend, can promote the reliability, consequently it is very necessary to set up temperature sensor at the main work part of air conditioner.

The existing situation is that: since the temperature sensor of the air conditioner compressor is generally fixed to the casing of the compressor by the fixing bracket, since the compressor is generally located outdoors, the temperature sensor fixed to the fixing bracket is easily loosened and slid in a length direction and/or a vertical direction thereof in a long time use, which may cause an increase in temperature measurement error, a decrease in operating efficiency of the air conditioner, and a decrease in operating life thereof. In order to solve the above problems, it is necessary to design a fixing frame adapted to a temperature sensor, which can be reliably fixed for a long time, and the structure of the fixing frame should be as simple as possible, so as to facilitate production, installation and use.

SUMMERY OF THE UTILITY MODEL

To the problem that exists, the technical purpose of the utility model is to provide a simple structure, the cost is lower be convenient for production, installation convenient and can be reliably fixed's adaptation temperature sensor's mount for a long time.

The mounting base is used for being fixedly connected with the compressor, and the connection mode is a conventional connection mode, which is not described herein. Generally, the temperature sensor is a strip-shaped body, the first cavity is used for accommodating the temperature sensor, and the first fin part and the second fin part clamp the temperature sensor, so that the temperature sensor is clamped, and therefore, the temperature sensor has reliable connection tightness. The temperature sensor may enter the first cavity from the first opening, or may enter the first cavity from two end faces of the first cavity. Therefore, the fixing frame is simple in structure, convenient to install and capable of reliably fixing the temperature sensor for a long time. It should be noted that, the first fin portion, the second fin portion and the mounting base may be an integral structure, and this should also be regarded that the first fin portion and the second fin portion are respectively and fixedly connected with the mounting base. The first and second fins may clamp the temperature sensor only by the first and second fins, or the first and second fins may clamp the temperature sensor on the mounting base or the mounting surface of the compressor.

Further, the fixer still includes thrust portion, thrust portion and installation base fixed connection, thrust portion is located the extension space of first cavity in the length direction. The thrust part is used for preventing the temperature sensor from sliding towards one end of the thrust part in the length direction of the temperature sensor, and the installation firmness of the temperature sensor can be further improved. The length direction of the first cavity is the length direction of the temperature sensor. The temperature sensor is generally in a strip-shaped structure, and the length direction of the temperature sensor refers to the length extending direction of the strip-shaped structure.

Specifically, the conventional temperature sensor generally has an expansion end with a relatively large size at one end in the length direction, and by providing the second cavity, when being mounted, the expansion end of the temperature sensor is located in the second cavity, that is, between the thrust portion and the first fin and the second fin, and because the first fin and the second fin are elastic elements, the first fin and the second fin also apply a certain clamping force to the expansion end so as to be firmly clamped between the thrust portion and the first fin and the second fin, that is, clamped in the second cavity. Obviously, the installation firmness of the temperature sensor can be further improved in the above mode, and the structure is still simpler. It should be noted that the size of the second cavity should match the size of the expansion end, and the size of the second cavity should be slightly smaller than the size of the expansion end due to the flexibility of the first and second fins, as will be apparent to those skilled in the art. The width direction of the temperature sensor is perpendicular to the length direction of the temperature sensor and parallel to the mounting surface of the fixing frame.

Referring to fig. 1 and fig. 2, a fixing frame 1 for a temperature sensor 2 of a compressor is provided in the present embodiment, where the fixing frame 1 includes a mounting base 10, a first fin 11, a second fin 12, and a thrust portion 15. The mounting base 10 is a sheet structure, and mounting holes for mounting on the surface of the compressor are reserved on two sides of the mounting base.

The first fin portion 11 and the second fin portion 12 are respectively and fixedly connected with the mounting base 10, and more specifically, the first fin portion 11, the second fin portion 12 and the mounting base 10 are of an integrated structure, which can significantly reduce the production cost of the fixing frame 1. Referring to fig. 1, the first fin 11 and the second fin 12 have a certain length. The first fin 11 and the second fin 12 are respectively arranged on both sides of the fixing frame 1 and are mirror-symmetrical with respect to a vertical plane of the mounting base 10. The first fin 11 and the second fin 12 form a first opening 13 at a side away from the mounting base 10. The first fin portion 11 and the second fin portion 12 enclose a first cavity 14, and the first cavity 14 is a reserved space for installing the temperature sensor 2. In this embodiment, the first fin portion 11 and the second fin portion 12 are both elastic elements, and when the temperature sensor 2 is located in the first cavity 14, the first fin portion 11 and the second fin portion 12 clamp the temperature sensor 2, so as to perform a fixing function. The first fin 11 is an arc-shaped surface on the surface facing the first cavity 14; the second fin 12 is curved on the side facing the first cavity 14, which increases the contact area between the first fin 11 and the second fin 12 and the temperature sensor 2, provides good stability and causes less wear in possible mutual movements.

The first fin 11 is provided with a first sliding contact body 111 at one end of the first opening 13, and similarly, the second fin 12 is provided with a second sliding contact body 121 at one end of the first opening 13. The upper surface of the first sliding contact body 111 is biased toward the second sliding contact body 121, and the upper surface of the second sliding contact body 121 is biased toward the first sliding contact body 111. The upper surfaces of the first sliding-connection body 111 and the second sliding-connection body 121 are cambered surfaces. The temperature sensor 2 can be inserted into the first cavity 14 by pressing open the first opening 13 at the location of the first opening 13, in such a way that the installation is very easy. The first sliding-contact body 111 and the second sliding-contact body 121 are arranged to reduce resistance when the temperature sensor 2 is pressed in, reduce wear of contact surfaces, and enhance reliability.

The temperature sensor 2 can also enter the first cavity 14 in another way, namely, the first cavity 14 is inserted from both ends of the first cavity 14, at this time, the first opening 13 needs to be firstly expanded to a certain size and kept during the insertion, and therefore, the installation way is inconvenient compared with the former way. In this embodiment, the temperature sensor 2 is preferably press-fitted from the first opening 13.

The thrust portion 15 and the mounting base 10 are fixedly connected by two connecting members 151. More specifically, the thrust part 15, the mounting base 10, and the connecting member 151 are an integrated structure, which contributes to reduction in production cost and improvement in overall strength. The thrust portion 15 is located in an extension space of the first cavity 14 in the longitudinal direction. When the temperature sensor 2 is located in the first cavity 14, the temperature sensor 2 cannot slide in the longitudinal direction toward the thrust portion 15 side due to the interference of the thrust portion 15, and thus the mounting stability is further improved.

The mounting base 10 is provided with a second cavity 16 between the thrust portion 15 and the first and second fins 11 and 12. The width of the second cavity 16 is not smaller than the width of the first cavity 14 in the width direction of the temperature sensor 2. The width direction of the temperature sensor 2 is perpendicular to the length direction of the temperature sensor 2 and parallel to the mounting surface of the fixing frame 1.

Referring to fig. 3 and 4, the temperature sensor 2 has a strip structure, and one end thereof has an enlarged end 21. The outer dimension of the enlarged end 21 is larger than the rest of the temperature sensor 2. Also, the size of the enlarged end 21 matches the size of the second cavity 16, specifically, the enlarged end 21 is slightly larger than the second cavity 16. When the temperature sensor 2 is mounted. The enlarged end 21 is aligned with the second cavity 16. The other part of the temperature sensor 2 is aligned with the first cavity 14 and the temperature sensor 2 is pressed into the first cavity 14 through the first opening 13. At the same time, the enlarged end 21 is pressed into the second cavity 16. At this time, the first fin 11 and the second fin 12 clamp the temperature sensor 2. At this time, the thrust part 15, the first fin 11, and the second fin 12 clamp the enlarged end 21 of the temperature sensor 2. At the same time, the first fin 11 and the second fin 12 clamp other portions of the temperature sensor 2. Can install fast conveniently through above-mentioned mode fixedly temperature sensor 2 in above the mount 1, and temperature sensor 2 receives the multiple fixed of mount 1 has reliable installation fastness, is difficult for droing. And then, the wire harness 3 is connected with the temperature sensor 2, and in the embodiment, because the thrust part 15 and the mounting base 10 are both in a sheet shape and have a small volume, the wiring is also very convenient.

The present embodiment provides a fixing bracket 1 for a compressor temperature sensor 2. By arranging the first fin 11, the second fin 12, the thrust portion 15, and the like, the temperature sensor 2 can be quickly mounted and has reliable mounting firmness. Meanwhile, the fixing frame 1 is simple in structure, low in production cost and good in practicability and economical efficiency.

Example 2

Referring to fig. 5, the present embodiment provides another fixing frame 1 for a compressor temperature sensor 2.

On the basis of embodiment 1, the fixing frame 1 of the present embodiment is different in that:

the thrust portion 15 is connected to the mounting base 10 only by one of the connection members 151.

This has the advantage of further reducing the overall mass of the holder 1, reducing production costs, and it also enables multiple fixing of the temperature sensor 2 during use. That is, the fixing frame 1 of the present embodiment has a lower production cost, and at the same time, its performance is slightly degraded. The person skilled in the art can flexibly select a suitable fixing frame 1 for use according to actual conditions.

Except for the differences described above, the other parts of the fixing frame 1 in this embodiment that are not described are the same as those in embodiment 1.

Example 3

Referring to fig. 6, the present embodiment provides another fixing frame 1 for a compressor temperature sensor 2. On the basis of embodiment 1, the fixing frame 1 of the present embodiment is different in that:

the first fin portion 11 is not provided with the first sliding connection body 111. The second sliding body 121 is not provided on the second fin portion 12. The faces of the first fin 11 and the second fin 12 facing the first cavity 14 are not curved faces.

The advantage is that the production effort of the fastening bracket 1, i.e. the production costs, are significantly reduced, and that, likewise, multiple fastening of the temperature sensor 2 is possible during use. However, when the temperature sensor 2 is pressed into the first cavity 14 through the first opening 13 during installation and use, the first opening 13 should be first enlarged, otherwise damage to the first fin 11 or the second fin 12 or the temperature sensor 2 is easily caused. In summary, the fixing frame 1 of the present embodiment has a lower production cost, but is relatively inconvenient to install and use and has a reduced reliability. The person skilled in the art can flexibly select a suitable fixing frame 1 for use according to actual conditions.

Except for the differences described above, the other parts of the fixing frame 1 in this embodiment that are not described are the same as those in embodiment 1.

Example 4

Referring to fig. 7, the present embodiment provides another fixing frame 1 for a compressor temperature sensor 2.

On the basis of embodiment 1, the fixing frame 1 of the present embodiment is different in that:

the second cavity 16 is not provided between the thrust part 15 and the first fin part 11 and the second fin part 12.

The fixing frame has the advantages that the production difficulty of the fixing frame 1 is reduced to a certain degree, and the production cost is reduced. However, in use, the fixing effect for the temperature sensor 2 with the enlarged end 21 is relatively poor. Therefore, the fixing frame 1 of the present embodiment is particularly suitable for installing and using the temperature sensor 2 in the shape of a regular strip.

Except for the differences described above, the other parts of the fixing frame 1 in this embodiment that are not described are the same as those in embodiment 1.

It should be noted that the present invention is not limited to the embodiments, but rather to the space limitation. With reference to the above embodiments, those skilled in the art can easily think of various combinations of technical features in different embodiments, and the technical solutions obtained by the combinations obviously also belong to the technical content of the present invention. Similarly, modifications and equivalents of the technical solutions of the present invention made by those skilled in the art are also covered by the technical contents of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
