Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a fixing device for a temperature measuring sensor of a plum blossom contactor. Background Art

[0002] The existing plum blossom contactor includes a contactor body and four springs. The four springs are evenly divided into two groups, and the two groups of springs are respectively arranged at both ends of the contactor body. The gap between the two groups of springs is relatively wide. In order to prevent the contact pieces from spreading after the springs break, a circular metal hoop for strengthening the contactor body is generally sleeved on the contactor body between the two groups of springs. The contactor body includes a plurality of contact pieces arranged in a circular array, and the gap between adjacent contact pieces is very small, only 1-2 mm. Especially, the adjacent contact pieces on the inner circumference are closer to each other. Moreover, after adding a circular metal hoop to the plum blossom contactor, the distance for installing the temperature measuring sensor in the middle of the contactor is reduced, reducing the installation space of the temperature measuring sensor and making it more difficult to be stably bundled on the contactor. As a result, the existing installation structures of temperature measuring sensors are not applicable.

[0003] Therefore, in the case of only a narrow installation position on the plum blossom contactor with a circular metal hoop, how to stably install the temperature measuring sensor is a problem to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for a temperature measuring sensor of a plum blossom contactor, which is used to solve the problems of narrow installation position and unstable installation of the temperature measuring sensor on the strengthened plum blossom contactor in the prior art.

[0005] To solve the above technical problems, the utility model adopts the following solutions:

[0006] A fixing device for a temperature measuring sensor of a plum blossom contactor, the temperature measuring sensor includes an installation shell and a sensor chip assembly fixed in the installation shell. The fixing device for the temperature measuring sensor includes a base. The width of the base is equal to the width of the installation shell. The base is provided with an installation groove for fixing the installation shell, and a first wire passing hole and a second wire passing hole symmetrically opened on both sides of the installation groove on the base. One end of a metal tie strap is fixed on the base on the side of the first wire passing hole, and the other end of the metal tie strap sequentially passes through the first wire passing hole, the gaps on both sides of a single contact piece, and the second wire passing hole and is fixed on the base on the side of the second wire passing hole.

[0007] In some optional embodiments, the base is further provided with a first boss and a second boss. The first boss and the second boss are symmetrically installed with respect to the installation groove. The first wire passing hole is arranged between the first boss and the installation groove, and the second wire passing hole is arranged between the second boss and the installation groove. One end of the metal tie strap is fixed on the first boss, and the other end of the metal tie strap sequentially passes through the first wire passing hole, a single contact piece, and the second wire passing hole and is fixed on the second boss.

[0008] In some alternative embodiments, adaptability chamfers are provided at the fold corners of the first boss and the second boss close to the mounting groove side.

[0009] In some alternative embodiments, both ends of the metal tie strap are respectively fixed to the first boss and the second boss through first fixing members.

[0010] In some alternative embodiments, the first fixing member includes a screw, and threaded through holes for the screw to pass through are formed in the first boss and the second boss.

[0011] In some alternative embodiments, the base, the first boss, and the second boss are integrally formed by using brass parts.

[0015] In some alternative embodiments, two mounting ears are symmetrically provided on the two outer side walls in the width direction of the base.

[0016] Advantages of the present utility model:

[0017] For a temperature measuring sensor fixing device for a plum blossom contact of the present utility model, since the position for installing the temperature measuring sensor between two groups of springs on the plum blossom contact reinforced with a circular metal hoop is very narrow, therefore, when designing the fixing device for the temperature measuring sensor, the width of the base needs to be designed to be equal to the width of the installation shell of the temperature measuring sensor to ensure the minimization of the fixing device, so as to be able to fix the temperature measuring sensor in a narrow environment. In addition, the method of using a metal tie strap to bundle a single contact piece to install the temperature measuring sensor can also reduce the installation area of the temperature measuring sensor fixing device, be applicable to the plum blossom contact with an added fixing hoop, and realize the installation in a narrow environment;

[0018] In addition, the utility model provides threading holes on both sides of the temperature sensor, one end of the metal tie piece is fixed on one side of the temperature sensor, and the other end passes through two threading holes and a contact piece in sequence and is fixed on the other side of the temperature sensor. By designing the threading holes, the metal tie piece can pass directly through a single contact piece. Compared with the prior art, the metal tie piece needs to bypass all contacts and the length of the metal tie piece used is relatively long. The metal tie piece in the present application only needs to pass through both sides of a single contact piece and be fixed on the base, which can greatly reduce the length of the metal tie piece, save materials and thus reduce costs. In addition, only needing to be fixed on a single contact piece can also reduce the length of the force arm, increase the force of the metal tie piece on the contact piece, and allow the metal tie piece to bind the contact piece tightly, making the installation tighter and reducing the problem of loose connection of the temperature sensor fixing device.

[0030] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments:

[0031] Embodiment 1:

[0032] As Figures 1 to 6 shown, this embodiment provides a fixing device for a temperature sensor 8 of a plum blossom contact. The temperature sensor 8 includes a mounting shell and a sensor chip assembly fixed inside the mounting shell. The fixing device for the temperature sensor 8 includes a base 1. The width of the base 1 is equal to the width of the mounting shell. An installation groove for fixedly installing the mounting shell of the temperature sensor 8 is provided on the base 1, and a first wire passing hole 2 and a second wire passing hole 3 symmetrically opened on both sides of the installation groove are provided on the base 1. One end of a metal tie strap 12 is fixed on the base 1 on the side of the first wire passing hole 2, and the other end of the metal tie strap 12 passes through the first wire passing hole 2, the gaps on both sides of a single contact piece 11, and the second wire passing hole 3 in sequence and is fixed on the base 1 on the side of the second wire passing hole 3. The mounting shell is made of an insulating material.

[0033] Specifically, a first boss 4 and a second boss 5 are further provided on the base 1. The first boss 4 and the second boss 5 are symmetrically installed with respect to the installation groove. The first wire passing hole 2 is arranged between the first boss 4 and the installation groove, and the second wire passing hole 3 is arranged between the second boss 5 and the installation groove. One end of the metal tie strap 12 is fixed on the first boss 4, and the other end of the metal tie strap 12 passes through the first wire passing hole 2, the single contact piece 11, and the second wire passing hole 3 in sequence and is fixed on the second boss 5. The first wire passing hole 2 and the second wire passing hole 3 are opened along the width direction of the base 1.

[0034] In order to fix the metal tie strap piece 12 more firmly on the first boss 4 and the second boss 5, adaptive chamfers 6 are provided at the corners of the first boss 4 and the second boss 5 close to the mounting groove. In this way, when the metal tie strap piece 12 passes through the wire passing hole, the metal tie strap piece 12 is closely attached to the chamfer 6 and transitions above the first boss 4 and the second boss 5, and is more stably fixed above the first boss 4 and the second boss 5.

[0035] Specifically, both ends of the metal tie strap piece 12 are fixed to the first boss 4 and the second boss 5 through the first fixing members 7 respectively. The first fixing members 7 can be fixed by screws or clamped by buckles. In this embodiment, the first fixing members 7 can adopt screws. Threaded holes for the screws to pass through are provided on the first boss 4 and the second boss 5. A screw passes through one end of the metal tie strap piece 12 to fix the metal tie strap piece 12 on the first boss 4 above the threaded hole. The other end of the metal tie strap piece 12 passes through the first wire passing hole 2, the single contact piece 11 and the second wire passing hole 3 in sequence and is fixed to the second boss 5 by a screw.

[0036] In order to achieve good heat conduction effect, the base 1, the first boss 4 and the second boss 5 are integrally formed by brass parts, so that the bottom of the first boss 4, the bottom of the second boss 5 and the base 1 are on the same straight line. In this way, the temperature measuring sensor 8 is closely attached in the mounting groove, and the mounting groove is closely attached to the contact piece 11. In this way, the temperature of the contact piece 11 can be well conducted to the temperature measuring sensor 8.

[0037] In order to enable the base 1 to closely fit the contact piece 11, so that the temperature measuring sensor 8 in the mounting groove is closely attached to the contact piece 11, a second fixing member 9 for fixing the temperature measuring sensor 8 on the base 1 is provided on the base 1, and a fixing groove for installing the second fixing member 9 is provided at the bottom end of the base 1. The fixing member adopts a screw, and the fixing groove is a threaded hole groove matching the screw. After the screw is tightened, it is located inside the fixing groove.

[0038] In one implementation manner, two mounting ears 10 are symmetrically provided on the two outer side walls in the width direction of the base 1. The mounting ears 10 are reserved, and metal tie straps can be hung for traditional watchband-style installation.

[0039] The usage process of this embodiment:

[0040] Place the temperature sensor 8 in the installation groove of the fixing device, tighten the screw from the bottom end of the base 1 to fix the temperature sensor 8 in the installation groove. Take out a metal tie strap piece 12, fix one end of the metal tie strap piece 12 above the first boss 4, and then pass the other end of the metal tie strap piece 12 through the first wire passing hole 2, the contact piece 11 and the second wire passing hole 3. Tighten the metal tie strap piece 12 to ensure that the base 1 no longer shakes, and then fix the other end of the metal tie strap piece 12 to the second boss 5. Since the metal tie strap piece 12 only passes through a single contact piece 11, compared with the prior art where a watch band type is used to sleeve on all the contact pieces 11 for fixing, the metal tie strap needs to bypass all the contacts and the length of the metal tie strap used is longer. In this application, the metal tie strap piece 12 only needs to pass through both sides of a single contact piece 11 and be fixed on the base 1, which can greatly reduce the length of the metal tie strap piece 12, save materials and thus reduce costs. In addition, only fixing on a single contact piece 11 can also reduce the length of the force arm and increase the acting force of the metal tie strap piece 12 on the contact piece 11, which can make the metal tie strap piece 12 tighten the contact piece 11, make the installation more firm, and reduce the problem of loose connection of the fixing device of the temperature sensor 8.

[0041] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various deformations and improvements can be made without departing from the spirit and essence of the present invention, and these deformations and improvements are also regarded as the protection scope of the present invention.
