DETAILED DESCRIPTION

[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0046] like Figures 1 to 13 The present invention provides a temperature detection fixing clamp, a temperature detection device and mechanical equipment.

[0047] This embodiment discloses a temperature detection fixing clamp, including a fixing clamp body 210, a guide portion 230, a locking portion 220 and a temperature measurement joint portion;

[0048] The fixing clamp body 210 is provided with a heat collecting cavity 212 for placing the temperature component to be measured;

[0049] The guide part 230 and the locking part 220, the guide part 230 is arranged at the inlet end of the heat collection chamber 212, and is used to guide the temperature component to be measured to enter the heat collection chamber 212; the locking part 220 is arranged at the outlet end of the heat collection chamber 212, and the locking part 220 generates elastic deformation to apply a pressing force to the temperature component to be measured;

[0050] The temperature measuring joint part is connected to the fixing clamp body 210 , and is provided with a temperature measuring channel for placing the temperature sensor 10 , and heat exchange can be performed between the heat collecting cavity 212 and the temperature measuring channel; the temperature measuring joint part is connected with a clamping element 242 , and the clamping element 242 is used to fix the temperature sensor 10 .

[0051] In this embodiment, a heat collecting cavity for placing the temperature component to be measured is provided on the fixing clamp body, and a temperature measuring channel for placing the temperature sensor is provided on the temperature measuring joint. Heat exchange can be performed between the heat collecting cavity and the temperature measuring channel, that is, heat exchange is performed between the temperature component to be measured and the temperature sensor, so that the temperature sensor completes the temperature measurement of the temperature component to be measured.

[0052] In this embodiment, the heat collecting chamber 212 of the fixing clamp 20 is sleeved onto the outside of the temperature component to be measured through the guiding part, so as to prevent the temperature component to be measured from colliding with the fixing clamp body when the temperature component to be measured enters the heat collecting chamber, thereby preventing the fixing clamp body from damaging the surface structure of the temperature component to be measured; and the temperature component to be measured is locked at one end of the heat collecting chamber outlet through the locking part to prevent the temperature component to be measured from moving in the heat collecting chamber; the present invention fixes the temperature sensor in the temperature measuring channel through the clamping element to prevent the temperature sensor from moving in the temperature measuring channel, thereby ensuring the installation stability of the temperature component to be measured and the temperature sensor.

[0053] In this embodiment, the temperature component to be measured is connected to the temperature sensor through the fixing clamp body and the temperature measurement joint. During operation, it is only necessary to connect the temperature component to be measured and place it into the heat collecting cavity on the fixing clamp body, and place the temperature sensor into the temperature measurement channel in the temperature measurement joint. The installation is simple.

[0054] According to a further optimization scheme, the fixing clamp body 210 includes an annular heat conducting plate 211, the heat collecting cavity 212 is the inner cavity of the annular heat conducting plate 211, the annular heat conducting plate 211 is provided with a first baffle at the outlet end of the heat collecting cavity 212, and the annular heat conducting plate 211 is provided with a second baffle at the outlet end of the temperature measuring channel.

[0055] Among them, the annular heat conducting plate 211 is made of heat conducting material to ensure that heat can be transferred between the temperature piece to be measured and the temperature sensor, so as to realize temperature detection; the annular heat conducting plate 211 is set as an annular structure, and the middle part of the annular structure of the annular heat conducting plate 211 is the heat collecting cavity 212. Since the annular heat conducting plate 211 is an annular structure, when installing, the temperature piece to be measured can be directly inserted into the heat collecting cavity 212, and the operation of placing the temperature piece to be measured in the heat collecting cavity 212 can be completed. In the installation process, the temperature piece to be measured is introduced into the heat collecting cavity through the guide part, and the temperature piece to be measured is locked at one end of the heat collecting cavity outlet through the locking part to prevent the temperature piece to be measured from moving in the heat collecting cavity. Of course, the fixing clamp body 210 can also adopt other shapes or structures, such as C-shaped structure, rectangular parallelepiped, plate and other structures, and a component with a heat collecting cavity is fixedly connected at a later stage.

[0056] Preferably, the fixing clip 20 is composed of a single component made of a metal heat-conducting material. The metal material used in the fixing clip 20 generally has a significantly higher thermal conductivity than other materials such as resins. Therefore, the temperature change of the fixing clip 20 quickly follows the temperature change of the temperature piece to be measured. Through the fixing clip 20, the temperature sensor 10 can obtain instant heat from the surrounding surfaces of the temperature piece to be measured. That is, by using the fixing clip 20 to concentrate the heat of the temperature piece to be measured on the temperature sensor 10, the temperature sensor 10 detects the temperature change of the temperature piece to be measured without delay in the temperature change of the temperature piece to be measured, so the responsiveness of temperature detection is improved. The fixing clip 20 can be made of a suitable metal material that can clamp the temperature piece to be measured by elastic force, such as iron alloy, stainless steel, phosphor bronze, spring steel, etc. Moreover, the metal fixing clip, due to its high thermal conductivity, also has the function of collecting the heat of the temperature piece to be measured to the temperature sensor. Based on this heat collection effect, the thermal responsiveness of the temperature detection of the temperature sensor can be improved. The fixing clip is formed by punching and bending a metal plate, and has a simple overall structure, which can reduce the number of components and reduce the manufacturing cost of a temperature detection device for detecting the temperature of a temperature object to be measured. The fixing clip can be easily formed by stamping, and can be easily assembled to the temperature sensor by riveting the fins.

[0057] At the same time, the first baffle is a rear stop J, which is arranged on one side of the fixed clamp body 210 at the outlet end of the heat collecting chamber 212, and the rear stop J is arranged corresponding to the outlet end of the heat collecting chamber 212. The present application not only presses the temperature component to be measured by deforming the locking portion, but also limits the end of the temperature component to be measured in the axial direction by the rear stop J.

[0058] The second baffle is a front baffle H, which is arranged on one side of the fixed clamp body 210 at the outlet end of the temperature measuring channel, and the front baffle H is arranged corresponding to the outlet end of the temperature measuring channel. The present application clamps and fixes the temperature sensor 10 in the temperature measuring channel through a clamping element, and at the same time limits the end of the temperature sensor 10 in the axial direction through the front baffle H, so that the temperature sensor 10 can be stably connected to the fixed clamp body 210 within the range of the temperature measuring channel. When the temperature sensor 10 is vibrated, the temperature sensor 10 can also be stably installed in the fixed clamp 20.

[0059] A further optimized solution is that the guide portion 230 includes a guide vane 231, which is arranged on the outside of the feeding direction of the temperature piece to be measured entering the heat collecting chamber 212, and the guide vane 231 is arranged at the entrance end of the heat collecting chamber 212 and is fixedly connected to the fixing clamp body 210, and the guide vane 231 is arranged obliquely relative to the fixing clamp body 210, and the free end of the guide vane 231 is arranged away from the heat collecting chamber 212.

[0060] Among them, the guide plate 231 is arranged obliquely, and the distance between the guide plate 231 and the temperature piece to be measured decreases with the feeding direction of the temperature piece to be measured, that is, the free end of the guide plate 231 faces the outside of the feeding direction, and the fixed end of the guide plate 231 is arranged close to the temperature piece to be measured. When the temperature piece to be measured enters the heat collecting chamber 212, the temperature piece to be measured will first contact the obliquely arranged guide plate 231. In the process of the temperature piece to be measured and the heat collecting chamber 212 being nested, the guide plate 231 will guide the temperature piece to be measured to enter the heat collecting chamber 212, thereby preventing the temperature piece to be measured from colliding with the fixing clamp body 210 during the process of entering the heat collecting chamber 212, thereby preventing the fixing clamp body 210 from damaging the surface structure of the temperature piece to be measured. In the present application, there are two ways to fit the temperature piece to be measured and the heat collecting chamber 212. One is to insert the temperature piece to be measured into the heat collecting chamber 212 of the fixing clamp body 210, and the other is to fit the heat collecting chamber 212 of the fixing clamp body 210 onto the outside of the temperature piece to be measured. The two methods are just different in description, but the installation process and installation effect are the same.

[0061] Of course, in this embodiment, the guide plate 231 can also be arranged parallel to the feeding direction of the temperature piece to be measured entering the heat collecting chamber 212. The guide plate 231 is an elastic member. Before the installation of the temperature piece to be measured and the heat collecting chamber 212, it is necessary to turn the free end of the guide plate 231 to make the guide plate 231 tilted to prevent the temperature piece to be measured from colliding with the fixing clamp body 210 during the process of entering the heat collecting chamber 212, thereby preventing the fixing clamp body 210 from damaging the surface structure of the temperature piece to be measured.

[0062] A further optimized solution is that the locking portion 220 includes a spring piece 221, which is arranged on the inner side of the feeding direction of the temperature piece to be measured entering the heat collecting chamber 212, the spring piece 221 is arranged at the outlet end of the heat collecting chamber 212 and is fixedly connected to the fixing clamp body 210, the spring piece 221 is arranged obliquely relative to the fixing clamp body 210, the free end of the spring piece 221 is arranged in the heat collecting chamber 212, and the spring piece 221 is used to apply extrusion force to the temperature piece to be measured.

[0063] Among them, the spring piece 221 is arranged inside the heat collecting chamber 212, and the free end of the spring piece 221 is bent toward the inside of the heat collecting chamber 212, and the fixed end of the spring piece 221 is fixedly connected to the fixing clamp body 210, which causes the distance between the spring piece 221 and the temperature piece to be measured to decrease with the feeding direction of the temperature piece to be measured, so that the spring piece 221 applies an extrusion force to the temperature piece to be measured to realize the locking function.

[0064] Preferably, the free end of the spring piece 221 is bent, and the shape of the free end of the spring piece 221 is similar to the shape of a "√" sign. An end hole 2A1 is provided at the position where the temperature piece to be measured contacts the spring piece 221, and the free end of the spring piece 221 is clamped in the end hole 2A1 of the temperature piece to be measured, thereby further realizing the locking function of the locking portion 220 on the temperature piece to be measured.

[0065] In the present invention, heat exchange can be performed between the heat collection chamber 212 and the temperature measurement channel. There are two arrangements of the heat collection chamber 212 and the temperature measurement channel. The first arrangement is that the temperature measurement channel and the heat collection chamber 212 are arranged on both sides of the fixing clamp body 210. The second arrangement is that the temperature measurement channel is arranged in the heat collection chamber 212. This is discussed in detail below.

[0066] like Figures 1 to 8 As shown, the arrangement of the heat collection chamber 212 and the temperature measurement channel is as follows: the temperature measurement channel and the heat collection chamber 212 are arranged on both sides of the fixing clamp body 210, the clamping element 242 is arranged outside the heat collection chamber 212, and the temperature measurement channel is arranged between the fixing clamp body 210 and the clamping element 242.

[0067] Among them, the annular heat conducting plate 211 includes a base A, a base wall B1, a base wall B2, a side wall C1, a side wall C2 and a curved portion D. All components are arranged in a clockwise circular pattern with a base A, a curved portion D, a side wall C2, a curved portion D, a base wall B2, a base wall B1, a curved portion D, a side wall C1 and a curved portion D. The annular cross-section of the fixing clamp body 210 is a rectangle, that is, the cross-section of the annular heat conducting plate 211 composed of all components is a rectangle or an approximately rectangular shape. The annular heat conducting plate 211 here is an integrated structure rather than a split structure. The middle part surrounded by all components is the heat collecting chamber 212. Since the curved portion D is designed to protrude outward and the curved portion D can be deformed, the base wall B1 and the base wall B2 have an elastic clamping force, thereby applying a holding force to the temperature component to be measured in the heat collecting chamber 212. At the same time, the base wall B1 and the base wall B2 can be an integrated structure, that is, the base wall B1 and the base wall B2 are fixedly connected, and the two are in the same plane; of course, the base wall B1 and the base wall B2 can also be a non-contact design, that is, there is a gap between the base wall B1 and the base wall B2, so that the installation space of the heat collection chamber 212 is larger and can accommodate more temperature components of different sizes to be measured.

[0068] The temperature measurement channel and the heat collection chamber 212 are arranged on both sides of the base A, and the base wall B1 and the base wall B2 are arranged on the opposite side of the base A. The guide part 230 is preferably a pair of guide pieces 231, and the pair of guide pieces 231 are arranged at the inlet end of the heat collection chamber 212, and the pair of guide pieces 231 are fixedly connected to the base wall B1 and the base wall B2 respectively. The locking part 220 is preferably a pair of spring pieces 221, and the pair of spring pieces 221 are arranged at the outlet end of the heat collection chamber 212, and the pair of spring pieces 221 are fixedly connected to the base wall B1 and the base wall B2 respectively. The free end of the spring piece 221 is bent, and the shape of the free end of the spring piece 221 is similar to the shape of the "√" sign. The free end of the spring piece 221 is clamped in the end hole 2A1 of the temperature component to be measured, and the locking function of the locking part 220 on the temperature component to be measured is further realized. The guide piece 231 and the spring piece 221 are arranged at the two ends of the base wall B1 and the base wall B2, and face opposite directions.

[0069] The temperature measurement joint is a clamping joint, which includes a joint body 241. The joint body 241 in this embodiment shares the same base with the base A. The joint body 241 includes the base A and the two ends of the base A extending along the feeding direction of the temperature piece to be measured, that is, the joint body 241 includes the base A and the extension plates at both ends of the base A. The clamping element 242 is fixedly connected to the joint body 241. The clamping element 242 in this application is preferably a fin, which will undergo plastic deformation when a pressing force is applied, thereby pressing the temperature sensor 10, thereby clamping and fixing the temperature sensor 10 in the temperature measurement channel. There is at least one fin in this application. In this embodiment, there are four fins, two groups of two, and the two groups of fins are respectively arranged at the head and tail sides of the temperature measurement channel. The two fins in each group are arranged oppositely, and the channel between the two fins is the temperature measurement channel. Of course, there can also be two fins, and the two fins are respectively arranged at the head and tail sides of the temperature measurement channel, and the gap spaces of the two fins are arranged oppositely to form a temperature measurement channel.

[0070] The front end of each fin of the present embodiment is arranged at a position away from the temperature body to be measured toward the outer peripheral side. Therefore, it is possible to prevent the front end of the fin from rubbing against the surface of the temperature body to be measured and causing damage. Before the fin is riveted, the distance between the top end of the fin and the main body 241 of the coupling part is greater than the distance between the top end of the fin and the main body 241 of the coupling part after pressing. After riveting, the fin is plastically deformed to flatten the temperature sensor 10 along the thickness direction. Since the fin will exert pressure on the temperature sensor 10 after riveting, in order to avoid damage to the temperature sensing element caused by pressure, the fin will be arranged away from the position where the temperature sensing element is located. Preferably, the fin is arranged near the front end or rear end of the coupling part. The length of the fin is set so as not to interfere with each other after riveting.

[0071] The front stop H and the rear stop J are respectively fixedly connected to the two ends of the coupling body 241 along the feeding direction of the temperature piece to be measured, and are arranged on both sides of the coupling body 241. The front stop H is arranged on the side away from the heat collecting chamber 212, which can prevent the fixing clamp 20 from interfering with the temperature piece to be measured during the assembly process. Preferably, the front stop H is arranged perpendicular to the coupling body 241, and of course, a certain angle can also be set.

[0072] The responsiveness of the temperature detection device 1 is indicated by the test results of the heating time constant τ. The heating time constant τ is the time required for the temperature sensing body 110 to reach 63.2% of the initial temperature difference.

[0073] Comparative Example 1: The temperature sensor 10 does not have any metal components such as the fixing clip 20 around it. The temperature sensor 10 of Comparative Example 1 exposes the protection component 120 covering the temperature sensing body 110 .

[0074] The temperature sensor of Comparative Example 1 placed at room temperature was pressed onto a metal plate heated to 100° C. to simulate the temperature component to be tested in use, and the heating time constant τ was measured. The heating time constant τ was 45 seconds.

[0075] The heat generation time constant τ measured when the fixing clip 20 of the temperature detection device 1 of the present embodiment was attached to a metal plate of a temperature-tested object and heated to 100° C. was 16 seconds.

[0076] By comparing Comparative Example 1 with the present embodiment, it can be seen that the heat collection effect based on the fixing clip 20 contributes more to the improvement of the responsiveness than that of Comparative Example 1.

[0077] like Figures 9 to 13 As shown, the arrangement of the heat collection chamber 212 and the temperature measurement channel is as follows: the temperature measurement channel is arranged in the heat collection chamber 212, the clamping element 242 is arranged inside the heat collection chamber 212, and the temperature measurement channel is arranged between the fixing clamp body 210 and the clamping element 242.

[0078] The fixing clamp in this embodiment is a second fixing clamp 60, and the second fixing clamp 60 includes a fixing clamp body 210, a guide part 230, a locking part 220 and a temperature measurement joint part. The temperature measurement joint part in this embodiment is a clamping part 600, and the clamping part 600 includes a clamping part body 610 and a clamping element 242. The clamping part body 610 includes a first wall 611, and the first wall 611 is the base A of the annular heat conducting plate 211. The temperature measurement channel on the clamping part body 611 is arranged in the heat collection cavity 212, and a temperature sensor is arranged in the temperature measurement channel. The temperature body to be measured is arranged in the heat collection cavity 212, that is, the temperature sensor 10 is arranged between the first wall 611 and the temperature piece to be measured, and the temperature piece to be measured is directly contacted with the temperature sensor 10 without passing through a component. In this embodiment, the temperature sensor 10 and the temperature piece to be measured are both arranged inside the fixing clamp body 210, and the fixing clamp 60 is thermally combined with the temperature sensor 10, so that the heat of the temperature body to be measured is concentrated on the temperature sensor 10 through heat conduction through the fixing clamp 60. Therefore, heat is directly conducted from the temperature-to-be-measured member to the temperature sensor 10 , thus contributing to further improvement of responsiveness.

[0079] The front baffle H is fixedly connected to the end of the first wall 611. The front baffle H is arranged corresponding to the outlet end of the temperature measurement channel. In this application, the temperature sensor 10 is clamped and fixed in the temperature measurement channel by a clamping element. At the same time, the front baffle H limits the end of the temperature sensor 10 in its axial direction, so that the temperature sensor 10 can be stably connected to the fixed clip body 210 within the range of the temperature measurement channel. When the temperature sensor 10 is vibrated, the temperature sensor 10 can also be stably installed in the fixed clip 60. In this embodiment, the rear baffle J can be provided or not. In this embodiment, a side baffle 213 is fixedly connected to the fixed clip body 210, and the chamfers 2A2 and 2A3 on the object to be measured have different sizes. When one of the chamfers cooperates with the side baffle 213 of the fixed clip 20, it can prevent the object to be measured from being installed in the wrong direction. That is, the side of the fixed clip 20 with the side baffle 213 can only cooperate with the side of the object to be measured with the chamfer 2A3 to make the fixed clip installed in place so as to play a limiting role.

[0080] The number of fins in this application is at least one. In this embodiment, four fins are provided, two in a group. The two groups of fins are respectively arranged on the head and tail sides of the temperature measurement channel. The two fins in each group are arranged opposite to each other, and the channel between the two fins is the temperature measurement channel. The first wall 611 is bent along three side surfaces of the temperature sensor 10 to form an approximate shape of "凵". As Fig.10 shown, the cross-section of the clamping part main body 610, the cross-section of the temperature measurement channel formed by the fins, and the cross-section corresponding to the outer shape of the temperature sensor 10 are the same; that is, the clamping part main body 610 and the fins together form the temperature measurement channel, and the temperature sensor 10 is arranged in this temperature measurement channel. The temperature measurement surface of the temperature sensor 10 is in direct contact with the object to be measured. In order to facilitate the fin riveting operation and to avoid the fins contacting the object to be measured, the joint part between the fins and the temperature sensor is formed thinner than in the first embodiment.

[0081] In this embodiment, considering the contribution degree of heat conduction to the temperature sensing body 110, it is preferably arranged in the clamping part 600 throughout the temperature sensing area 10R set including the temperature sensing element 111 and the electric wire 112. In the temperature sensing area 10R of the temperature sensor 10 covered by the clamping part 600, the heat of the object to be measured can be concentrated on the temperature sensor 10, and the direct attachment of the coolant droplets can be avoided.

[0082] A temperature detection device includes a temperature detection fixed clip 20, a temperature sensor 10, and a signal transmission member 50. The temperature measurement end of the temperature sensor 10 is arranged in the temperature measurement channel of the fixed clip 20 for detecting the temperature of the object to be measured; the input end of the signal transmission member 50 is electrically connected to the signal output end of the temperature sensor 10, and the signal transmission member 50 is also provided with a signal output end.

[0083] The device connects the temperature sensor 10 to the temperature component to be measured through a fixing clamp 20, and heat can be transferred between the temperature sensor 10 and the temperature component to be measured; the temperature sensor 10 is used to detect the temperature of the temperature component to be measured, and the signal transmission component 50 receives the signal of the temperature sensor 10 and transmits the signal, thereby completing the temperature detection work of the temperature component to be measured.

[0084] Preferably, the signal transmission component 50 is a connector, which is connected to the external device through a plug-in relationship. After the signal transmission component 50 receives the signal of the temperature sensor 10, it transmits the signal. The plug-in connection method is simple to operate, and the signal transmission is accurate and fast. Of course, the signal transmission component 50 of the present application can also transmit the received signal through a wireless connection.

[0085] At the same time, a cable 30 is connected between the signal transmission member 50 and the temperature sensor 10, and the cable 30 is used for signal transmission between the signal transmission member 50 and the temperature sensor 10; a protective cover 40 for protecting the cable 30 is provided on the outside of the cable 30.

[0086] According to a further optimized solution, the temperature sensor 10 includes a sensor body 110 and a protective component 120. The sensor body 110 is the temperature measuring end of the temperature sensor 10, and the sensor body 110 is used to detect the temperature of the temperature component to be measured. The protective component 120 is sleeved on the outside of the sensor body 110 and the signal output end of the temperature sensor 10, and the protective component 120 is insulated from the fixing clamp body 210 and / or the temperature component to be measured. The protective component 120 is used to protect the sensor body 110, the signal output end of the temperature sensor 10, and the cable 30 from external forces such as impact, and the fixing clamp body 210 and / or the temperature component to be measured are insulated by the protective component 120, which helps to insulate the sensor body 110 from the temperature measuring component.

[0087] Among them, the sensor body 110 is a temperature sensing body 110, and the temperature sensing body 110 has a temperature sensing element 111 and a pair of wires 112. The temperature sensing element 111 has a temperature sensing part that can detect temperature based on the change of thermistor relative to temperature change. The pair of wires 112 are electrically connected to the electrodes of the temperature sensing element 111 and are led out from the temperature sensing element 111 to the rear. Of course, the sensor body 110 in this embodiment can also detect temperature in other ways, which will not be repeated here. The protective component 120 covers the temperature sensing body 110, the wires 112 led out from the temperature sensing element 111, and a portion of the cable 30 connected to the wires 112. The end of the temperature sensor 10 away from the signal transmission component 50 is detachably connected with a protrusion 122 to prevent the temperature sensor 10 from falling out of the fixing clamp 20.

[0088] According to the further optimization scheme, the protective component 120 includes no less than two protective layers, the innermost protective layer is a fusible resin, and the outermost protective layer is a high temperature resistant resin. Among them, the inner layer of resin is made of the same material that is easier to combine with the cable insulation protective layer and has strong molten adhesiveness, such as PFA perfluoroalkyl compound. The purpose is that the inner layer of resin can better combine with the cable during the curing process to play a sealing role to prevent external water molecules from entering the temperature sensor; the outer layer of resin is made of a resin material with better high temperature resistance to prevent the protective component from melting easily in a high temperature environment. This will cause damage to the temperature sensor. This technical solution uses multiple layers of material as a protective component, which can effectively solve this problem.

[0089] The material of the protective layer can be, but is not limited to, fluorine resins such as polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA), and of course, thermoplastic resins, thermosetting resins, and appropriate resin materials. If the protective component 120 is made of a transparent resin, the appearance of the temperature sensing body 110 can be inspected based on the perspective of the protective component 120.

The introduction end of the extension portion 2A of the copper bar of the coil is provided with a chamfer 2A2 and a chamfer 2A3, which is convenient for introducing the fixing clip into the copper bar of the coil. The fixing clip body 210 is fixedly connected with a side stop 213, and the chamfer 2A2 and the chamfer 2A3 are of different sizes, and when one of the chamfers cooperates with the side stop 213 of the fixing clip 20, it can prevent positive and negative installation. That is, the side of the fixing clip 20 with the side stop 213 can only cooperate with the side of the coil copper bar 2A with the chamfer 2A3 so that the fixing clip can be installed in place.
