Abstract
Description
Technical Field
[0001] The utility model relates to a sensor bracket, in particular to a clamping type sensor bracket. Background Art
[0002] The stator winding of a rotating motor is assembled with copper wires, and current is passed through the copper wires of the stator winding to form a magnetic field, which in turn drives the rotor to rotate. However, when current passes through the copper wires, high heat is generated due to wire resistance, so a temperature sensor must be installed on the hot spot of the coil winding.
[0003] In order to clamp and fix the coil, the temperature sensors currently available on the market mostly use an elastic clamping method to fasten the sensor bracket and the coil. This method has a disadvantage that the elastic clamping is easy to loosen or even fall off due to the long-term high temperature and vibration of the motor. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a card-connected sensor bracket, which can improve flexibility and prevent falling off.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A snap-on sensor bracket includes a sensor clamping part and a coil clamping part. Both the sensor clamping part and the coil clamping part are position-limiting covering ring structures. The position-limiting covering ring structures match and fit the corresponding coil and sensor to limit the position. The coil clamping part and the coil are clamped and fixed by a snap-on assembly.
[0007] The clamping assembly comprises a concave hole and a protruding portion, and the concave hole and the protruding portion form a clamping relationship; the concave hole is arranged on the coil, and the protruding portion is correspondingly arranged on the coil clamping portion.
[0008] The clamping assembly comprises a concave hole and a protruding portion, and the concave hole and the protruding portion form a clamping relationship; the protruding portion is arranged on the coil, and the concave hole is correspondingly arranged on the coil clamping portion.
[0009] The recessed hole is a through hole or a blind hole.
[0010] The protrusion is semi-spherical, columnar or block-shaped, and the corresponding concave hole matches the shape of the protrusion.
[0011] The protrusion is arranged on one side, two sides or multiple sides of the coil clamping part that are in contact with the coil.
[0012] The clamping assembly comprises a groove and a locking tongue, wherein the locking tongue extends obliquely into the groove and is pressed tightly against the inner wall of the groove.
[0013] The clamping assembly includes a horizontal extension part, which is arranged at the bottom end of the outer side plate of the coil clamping part and fits the coil; the horizontal extension part is provided with a hook head, and the corresponding coil is provided with a hook hole, and the hook head is clamped with the hook hole.
[0014] The clamping assembly includes a horizontal extension part, which is arranged at the bottom end of the outer side plate of the coil clamping part and fits the coil; the horizontal extension part is provided with a hook hole, and the corresponding coil is provided with a hook head; the hook head is clamped with the hook hole.
[0015] The clamping assembly includes a slide groove and a slider. The corresponding coil is provided with a slide groove of a certain length, and the corresponding coil clamping part is provided with a slider. When the coil is inserted into the coil clamping part, the slide groove and the slider are clamped.
[0016] The utility model provides a snap-on sensor bracket, which has the following technical effects:
[0017] 1) In the present application, the positioning and fixation can be achieved without elastic force by inserting the limiting covering ring composed of the sensor clamping part and the coil clamping part and the clamping assembly; at the same time, the positioning can be achieved by clamping to avoid improper assembly.
[0018] 2) Since the sensor clamping part and the coil clamping part are both limit covering rings, the device can be in close contact with the coil; at the same time, the contact area between the device and the coil is increased by the clamping assembly, so that the temperature of the coil can be transmitted to the temperature sensor more quickly through the solid medium, thereby accelerating the thermal response speed.

[0031] Example 1
[0032] like Figure 1-3 As shown, a snap-on sensor bracket includes a sensor clamping portion 1 and a coil clamping portion 2. The sensor clamping portion 1 and the coil clamping portion 2 are integrally formed of a metal plate, and can also be made of other materials, such as plastic. The sensor clamping portion 1 is used to clamp the sensor 4, and the coil clamping portion 2 is used to clamp on the coil 3.
[0033] like Figure 4 As shown, the sensor clamping part 1 includes a bottom supporting part 1.1, which is integrally bent with the side limiting parts 1.2 on the left and right sides, and upper limiting parts 1.3 are continuously or spaced apart on the left and right side limiting parts 1.2, and one end of the bottom supporting part 1.1 is integrally bent with the end limiting part 1.4.
[0034] The specific structure of the sensor clamping part 1 is not limited to the structure indicated in the drawings of the present application specification, and can be set according to the size and shape of the actual sensor. For example, when the sensor is a square column, the outer shape of the sensor clamping part 1 is designed to be a square column; when the sensor is a cylindrical shape, the outer shape of the sensor clamping part 1 is designed to be a cylindrical shape. In short, the outer shape of the sensor clamping part 1 is updated and designed as the outer shape of the sensor changes to match it.
[0035] like Figure 4 As shown, the coil clamping part 2 comprises an inner plate 2.1, which is integrally formed with the sensor clamping part 1, and the outer side of the upper end of the inner plate 2.1 is integrally bent with the outer plate 2.2 through the end plate 2.3. The left and right sides of the inner plate 2.1 are integrally bent with the stopper plate 2.4.
[0036] The specific structure of the coil clamping part 2 is not limited to the structure indicated in the drawings of the present application specification, and can be set according to the size and structure of the actual coil.
[0037] In order to solve the problem of elastic clamping of the existing sensor bracket, the device adds a clamping component between the coil clamping part 2 and the coil 3, and fixes the device through the clamping component to prevent the device from falling off the coil 3 due to vibration.
[0038] like Figure 5 As shown, the clamping assembly includes a recessed hole 5 and a protruding portion 6 . The recessed hole 5 may be a through hole or a blind hole. The recessed hole 5 may be formed on the surface of the coil 3 or on the coil clamping portion 2 .
[0039] When the concave hole 5 is provided on the coil 3 , the protruding portion 6 is correspondingly provided on the coil clamping portion 2 , and the protruding portion 6 of the coil clamping portion 2 is inserted into the concave hole 5 of the corresponding coil 3 .
[0040] When the protruding portion 6 is provided on the coil 3 , the concave hole 5 is correspondingly provided on the coil clamping portion 2 , and the concave hole 5 of the coil clamping portion 2 is clamped with the protruding portion 6 of the coil 3 .
[0041] Preferably, the protrusion 6 is semi-spherical, which is convenient for clamping and disassembly. Alternatively, the protrusion 6 can also be a square column, a cylinder or other structures. The corresponding shape of the concave hole 5 matches the protrusion 6 or is mainly for the convenience of the protrusion 6 to be clamped.
[0042] like Figure 5 As shown, preferably, when the protrusion 6 is semi-spherical, the protrusion 6 can be set on the surface of the inner plate 2.1 or the outer plate 2.2 that contacts the coil 3; it can also be set on the surfaces of the inner plate 2.1 and the outer plate 2.2 that contact the coil 3 at the same time, and the double-sided clamping effect is better.
[0043] Example 2
[0044] like Figure 6-7 As shown, the difference from the embodiment 1 is that the clamping assembly comprises a groove 7 and a locking tongue 8, and the groove 7 and the locking tongue 8 are clamped with each other.
[0045] like Figure 8 As shown, preferably, the locking tongue 8 is in the shape of a sheet and is inclined toward the inner side of the groove 7, and the locking tongue 8 and the groove 7 can be frictionally locked.
[0046] Preferably, the surface of the groove 7 is roughened to increase friction.
[0047] like Figure 6 As shown, the sensor is arranged in parallel with the coil clamping part. Figure 7 As shown, the sensor and the coil clamping part are arranged vertically.
[0048] like Fig. 9 As shown, preferably, the groove 7 is arranged on the coil 3, and the corresponding locking tongue 8 is arranged on the outer side plate 2.2 of the coil clamping part 2. The shape of the groove 7 is consistent with the shape of the locking tongue 8.
[0049] Preferably, the notch edge of the groove 7 on one side of the locking tongue 8 is chamfered to prevent interference that would prevent the locking tongue 8 from fully fitting with the groove 7 .
