Description
Technical Field
[0001] The utility model belongs to the technical field of shells, and in particular relates to an integrated shell of a dry-type transformer temperature controller. Background Art
[0002] The dry-type transformer temperature controller is a device used to monitor and control the temperature of the dry-type transformer, which can ensure the normal operation of the transformer.
[0003] In the prior art, the temperature controller is referred to as a thermostat, and the housing of most thermostats is fixedly connected to the transformer cabinet by bolts. The housing of the existing thermostat has the following main shortcomings:
[0004] 1) Poor anti-slip performance: The surface of some thermostat shells is smooth. When personnel install the thermostat, due to insufficient friction force area between the hand and the shell surface, the thermostat often slips from the hand, causing damage to the thermostat;
[0005] 2) The installation of the circuit board is cumbersome: The thermostat housing generally uses screws and the support holes in the housing to fix the circuit board. This hole fixing method is cumbersome and wastes labor. Moreover, when locking the screws, it is easy for the personnel to forget to lock the holes, resulting in the circuit board being unreliably fixed and loose, which greatly increases the failure rate of the thermostat.
[0006] 3) Poor flexibility: The thermostat housing generally only supports one of the two buckles, the sliding buckle or the pillar buckle. When the user's opening size is too large, if the housing supports the sliding buckle, the housing as a whole is not firmly fixed and is easy to fall off; when the overall space of the transformer cabinet is small, if the housing supports the pillar buckle, it is necessary to lock the screws to fix the pillar, which is not conducive to personnel operation in a small space.
[0007] Therefore, there is an urgent need to improve the structure of the existing temperature controller housing and provide an integrated housing for a dry-type transformer temperature controller to solve at least one technical problem in the above-mentioned prior art. Utility Model Content
[0008] The utility model aims to address the deficiencies in the prior art and to provide an integrated housing for a dry-type transformer temperature controller which has a reasonable design, a simple structure, good anti-slip performance, is convenient for fixing circuit boards, and has good installation flexibility.
[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0010] An integrated housing for a temperature controller of a dry-type transformer comprises a box structure and a back cover. The box structure is formed by integral injection molding of a face cover and four side panels. The face cover is provided with positioning holes penetrating through the front and rear surfaces for positioning components on a circuit board. The inner walls of two opposite side panels are correspondingly provided with card slots extending along the front and rear directions for carding at both ends of the circuit board. The rear outer walls of the two opposite side panels are correspondingly provided with a first anti-slip structure. The back cover is detachably connected to the rear end of the box structure through a connecting assembly.
[0011] Furthermore, the four outer corners of the box structure are each provided with a second anti-slip structure, and the second anti-slip structure is located at the rear of the box structure.
[0012] Preferably, the second anti-slip structure and the first anti-slip structure are both composed of a plurality of anti-slip grooves distributed at front and rear intervals.
[0013] Preferably, the four inner corners of the box structure are provided with first threaded holes extending in the front-to-back direction, the connecting assembly includes a first screw, and the four corners of the rear cover are threadedly connected to the first threaded holes through the first screw.
[0014] Preferably, a second threaded hole extending in the front-to-back direction is correspondingly provided on the middle inner wall of the two opposite side panels, and the connecting assembly also includes a second screw, and both sides of the rear cover are threadedly connected to the second threaded hole through the second screw.
[0015] Furthermore, the first mounting structures are provided at the four outer corners of the box structure; and the second mounting structures are correspondingly provided on the outer walls of two opposite side panels.
[0016] Preferably, the first mounting structure includes a positioning rack and two sliding mounting grooves, the two sliding mounting grooves are respectively extended in the front-to-back direction and are opened on two adjacent side plates, and the positioning rack extends in the front-to-back direction and is arranged between the two sliding mounting grooves.
[0017] Preferably, the second mounting structure comprises two fixed mounting holes, which are respectively opened at the front and middle of the side plate.
[0018] Preferably, the first mounting structure is located in front of the second anti-slip structure, and the second mounting structure is located in front of the first anti-slip structure.
[0019] The utility model adopts the above technical solution and has the following technical effects:
[0020] The box structure of the utility model is formed by integral injection molding of a face cover and four side panels, which can reduce assembly and reduce labor costs; by providing positioning holes on the face cover that penetrate the front and rear surfaces for positioning components on the circuit board, not only can a space be provided for components on the circuit board arranged parallel to the face cover that need to be exposed, such as lights, digital tubes, buttons, etc., but also the above-mentioned circuit board components can be conveniently clamped and fixed in the corresponding positioning holes, ensuring that the circuit board and the components thereon will not shake up and down or left and right, and can be firmly fixed inside the shell; by correspondingly providing clamping grooves extending along the front and back directions on the inner walls of two opposite side panels for clamping the two ends of the circuit board, the two ends of the circuit board arranged vertically on the face cover can be conveniently and quickly clamped into the clamping grooves inside the shell, the circuit board can be firmly fixed and not easy to loosen, thereby making it more convenient and simple for users to maintain and replace the circuit board, and it is also more flexible than the traditional method of fixing with screws.

[0029] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:
[0030] like Figure 1-3 As shown in FIG. 1 , the integrated housing of the dry-type transformer temperature controller of the utility model comprises a box structure 10 and a back cover 20. The back cover 20 is detachably connected to the rear end of the box structure 10 through a connecting assembly. The box structure 10 is integrally injection-molded by a face cover 11 and four side panels 12, thereby reducing assembly and reducing labor costs. The face cover 11 is provided with positioning holes 30 that penetrate through the front and rear surfaces for positioning components on the circuit board, and the inner walls of the two opposite side panels 12 are correspondingly provided with card slots 40 that extend along the front and rear directions for carding the two ends of the circuit board.
[0031] In the present embodiment, there are multiple groups of positioning holes 30, which are respectively used to position the lights, digital tubes, and buttons on the circuit board. The positioning holes 30 can not only provide space for components such as lights, digital tubes, and buttons that need to be exposed on the circuit board arranged with the parallel surface cover 11, but also can conveniently snap-fit and fix the above-mentioned circuit board components in the corresponding positioning holes 30, ensuring that the circuit board and the components thereon will not shake up and down or left and right, and can be firmly fixed inside the shell; through the provided card slots 40, the two ends of the circuit board arranged with the vertical surface cover 11 can be conveniently and quickly snap-fitted into the card slots 40 inside the shell, and the circuit board is firmly fixed and not easy to loosen; during installation, the circuit board arranged with the parallel surface cover 11 is installed first, and then the circuit board arranged with the vertical surface cover 11 is installed. This installation method can make it more convenient and simple for users to maintain and replace the circuit board, and is more flexible than the traditional method of fixing with screws.
[0032] In order to improve the anti-skid performance of the shell, based on the above structure, further, a first anti-skid structure 50 is correspondingly provided on the rear outer wall of the two side panels 12; the first anti-skid structure 50 is composed of a plurality of anti-skid grooves distributed at front and rear intervals.
[0033] In this embodiment, by setting up the first anti-slip structure 50, when the user locks the back cover 20, the fingers of one hand can contact the anti-slip grooves of the first anti-slip structure 50, and the friction between one hand and the shell is increased by increasing the contact area and the roughness. When the user locks the screws of the back cover 20, the shell can be firmly grasped by one hand without sliding, thereby achieving the purpose of improving the anti-slip effect, thereby facilitating the other hand to perform the screw locking operation.
[0034] As a preferred embodiment, based on the above structure, further, a second anti-slip structure 60 is provided at the four external corners of the box structure 10. The second anti-slip structure 60 is located at the rear of the box structure 10. The second anti-slip structure 60 is composed of a plurality of anti-slip grooves distributed at front and rear intervals.
[0035] In this embodiment, by setting up the second anti-slip structure 60, when the user fixes or removes the shell, the fingers of one hand or both hands can contact the anti-slip grooves of the second anti-slip structure 60. The anti-slip grooves increase the contact force area between the fingers and the shell. At the same time, the anti-slip grooves also increase the roughness of the contact surface, which greatly increases the friction between the fingers and the shell, so that the shell will not easily slip out of the hand, thereby avoiding damage to the shell.
[0036] like Figure 3 As shown, as a preferred embodiment, based on the above structure, preferably, the four internal corners of the box structure 10 are provided with first threaded holes 13 extending along the front-to-back direction, the connecting assembly includes a first screw, and the four corners of the back cover 20 are threadedly connected to the first threaded hole 13 through the first screw.
[0037] On the basis of the above structure, further, a second threaded hole 14 extending along the front-to-back direction is correspondingly provided on the middle inner wall of the two relative side panels 12, and the connecting component also includes a second screw, and both sides of the rear cover 20 are threadedly connected to the second threaded hole 14 through the second screw.
[0038] like Figure 1 or Figure 2 As shown, in order to improve the flexibility of shell installation, on the basis of the above structure, the utility model further provides a first mounting structure 70 at the four external corners of the box structure 10, and the first mounting structure 70 is located in front of the second anti-slip structure 60. A second mounting structure 80 is correspondingly provided on the outer walls of the two side panels 12, and the second mounting structure 80 is located in front of the first anti-slip structure 50.
[0039] On the basis of the above structure, preferably, the first mounting structure 70 includes a positioning rack 71 and two sliding mounting grooves 72, the two sliding mounting grooves 72 are respectively extended in the front-to-back direction and are opened on two adjacent side panels 12, and the positioning rack 71 extends in the front-to-back direction and is arranged between the two sliding mounting grooves 72; the second mounting structure 80 includes two fixed mounting holes 81, and the two fixed mounting holes 81 are respectively opened in the front and middle parts of the side panel 12.
[0040] In this embodiment, the first mounting structure 70 and the second mounting structure 80 can be used to install the sliding buckle and the pillar buckle respectively, so that the housing can be fixed by both the sliding buckle and the pillar buckle. By setting up the first mounting structure 70, when the transformer cabinet space is small (for example, the opening size of the transformer cabinet is 80mm*80mm, and the rear size of the shell is 75mm*75mm), the conventional sliding buckle in the prior art in the field can be used to fix the shell. It should be noted that the sliding buckle is a commercially available cabinet instrument housing accessory, for example, it can be a mounting ear with product number 5-11 sold by Yuyao Jinggang Mould Co., Ltd.; during installation, the user only needs to slide the two side slide bars of the sliding buckle into the two sliding mounting grooves 72 of the first mounting structure 70 of the shell, and selectively engage the middle teeth of the sliding buckle with the positioning rack 71 of the first mounting structure 70 of the shell to complete the installation of the sliding buckle on the shell, and then push the shell inward in the narrow space in line with the opening of the transformer cabinet, and use the sliding buckles around the shell to fill the gap between the shell and the cabinet to fix the shell. The fixing method using the sliding buckle has the advantages of being simple and practical, saving space, high reliability, and convenient disassembly and replacement. By setting up the second mounting structure 80, when the opening size of the transformer cabinet is large, the conventional support clips in the prior art in the field can be used to fix the shell. It should be noted that the support clip is a commercially available instrument mounting frame accessory, for example, it can be a shell with the brand of Shengchang and the product name of Instrument Mounting Frame-2 sold by Cixi Shengchang Industrial Co., Ltd. During installation, the user only needs to insert the pins at both ends of the support clip into the two fixed mounting holes 81 of the second mounting structure 80 of the shell, and then use a screwdriver to lock the screws of the support clip onto the transformer cabinet, thereby completing the fixation of the shell.
[0041] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
