Description

Technical Field

[0001] This utility model relates to the field of circuit breaker installation technology, and in particular to a rail connector for circuit breakers. Background Technology

[0002] Currently, the installation method for miniature circuit breakers involves first installing a DIN rail on a wall or panel, then mounting the miniature circuit breaker onto the rail connector, and finally mounting the rail connector onto the DIN rail. However, commercially available rail connectors have several drawbacks. For example, the circuit breaker cannot be quickly installed onto the rail connector, nor can the rail connector be quickly installed onto the rail. Furthermore, the rail connector is difficult to remove from the rail, making disassembly very inconvenient. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rail connector for circuit breakers, which has the characteristics of convenient installation and disassembly, stable fixing effect, and more reasonable overall structural design.

[0004] The technical solution adopted by this utility model to solve its technical problem is a guide rail connector for a circuit breaker. The guide rail connector includes a sliding buckle plate, a mounting base, and an elastic element. The sliding buckle plate includes a buckle plate main body, and two first side plates are provided on the rear side of the buckle plate main body. The two first side plates are vertically flush and each has a first locking block at the upper end. The mounting base includes a base main body and a base fixing part provided at the upper and lower ends of the base main body. The first side plates are supported and fitted on the front side of the base main body. Two second side plates are provided on the upper side of the front side of the base main body. The two second side plates are vertically flush and the first side plates are vertically flush. A second locking block is formed on the lower side of each of the two side plates. Two inverted L-shaped first guide feet are also provided on the lower front side of the base body. The first guide feet are arranged facing each other and slide in contact with the buckle body. Two support plates are also provided on the base body. The support plates are set to support the bottom surface of the circuit breaker. The base fixing part is attached to the bottom surface of the circuit breaker and has a connecting hole for screws to pass through. One end of the elastic element is connected to the buckle body and the other end of the elastic element is connected to the base body. The first locking block cooperates with the second locking block through the elastic element to fix the guide rail connector to the guide rail.

[0005] The advantages of the above technical solution are as follows: By combining the elastic element, the first locking block on the first side plate, the second locking block on the second side plate, and the two inverted L-shaped first guide feet to form a fixed structure for the guide rail connector to cooperate with the guide rail, the guide rail connector is convenient and labor-saving to operate when disassembling and installing the circuit breaker. It is only necessary to slide the buckle plate to complete the engagement or removal with the guide rail. Through the base fixing parts set at the upper and lower ends of the base body, the guide rail connector can be easily installed on the back of the electrical equipment. By setting two support plates on the base body, the support plates support the bottom surface of the circuit breaker, thereby increasing the strength of the base body and ensuring the reliability of use. Therefore, the overall structure design is reasonable, convenient for installation and disassembly, and the fixing effect is stable.

[0006] Furthermore, the base body is also provided with two inverted L-shaped second guide feet, which are arranged facing each other and located below the first guide feet. The second guide feet slide and engage with the buckle body.

[0007] The advantages of the above technical solution are: by setting two opposing inverted L-shaped second guide feet on the main body of the base, the sliding of the sliding buckle plate is more stable in cooperation with the first guide foot. At the same time, the first and second guide feet are also easy to form, and the structural design is reasonable.

[0008] Furthermore, a third side plate is vertically connected to the corresponding position of the first side plate, and the second guide foot slides and contacts the third side plate. Each of the third side plates is also provided with a limiting foot, which is positioned below the second guide foot. The limiting foot is used to cooperate with the second guide foot to limit the sliding buckle plate.

[0009] The advantages of adopting the above technical solution are as follows: by setting a third side plate with limiting feet, the matching position of the sliding buckle on the mounting base is guaranteed, avoiding the phenomenon of the sliding buckle detaching. It also makes the installation stability of the elastic component that matches the sliding buckle and the mounting base more stable, and the use of the guide rail connector is more reasonable.

[0010] Furthermore, the bottom wall of the first card block forms an inclined plane with an angle of A with the main body of the base, the angle of A being in the range of 5° to 9°, and the bottom wall of the second card block forms an inclined plane with an angle of B with the main body of the base, the angle of B being in the range of 35° to 41°.

[0011] The advantages of the above technical solution are as follows: setting the bottom wall of the first card block as an inclined plane with angle A and setting the bottom wall of the second card block as an inclined plane with angle B, these two inclined planes help to easily snap the first card block and the second card block onto the guide rail. Therefore, the sliding buckle plate will be smoothly fastened to the guide rail. Moreover, after many experiments, the matching feel of the above two angle ranges is the best, and the structural design is reasonable.

[0012] Furthermore, a first stop is provided on the rear side of the main body of the buckle plate, and a second stop is provided on the front side of the main body of the base. The second stop is positioned directly below the first stop. A first mounting post located at the center line is provided on the lower side of the first stop, and a second mounting post located at the center line is provided on the upper side of the second stop. One end of the elastic member is sleeved on the first mounting post, and the other end of the elastic member is sleeved on the second mounting post.

[0013] The advantages of the above technical solution are: by setting a first stop with a first mounting post and a second stop with a second mounting post, the elastic element is firmly fixed, so that the elastic element can effectively provide elastic force for the sliding buckle plate. The structural design is reasonable, simple and effective.

[0014] Furthermore, the lower front side of the base body is provided with two fourth side plates. The two fourth side plates are vertical and flush. The fourth side plates and the second side plate cooperate to form a positioning groove on the base body. The positioning groove is used to cooperate with the guide rail.

[0015] The advantages of adopting the above technical solution are: by setting a fourth side plate, the fourth side plate and the second side plate form a positioning groove on the main body of the base, during installation, the guide rail connector with electrical equipment can be quickly and accurately placed on the guide rail through the positioning groove, and the structural design is more reasonable.

[0016] Furthermore, the sliding buckle plate also includes a buckle plate handle portion, which is disposed on the lower side of the buckle plate body portion, and the buckle plate handle portion is provided with a handle opening.

[0017] The advantages of adopting the above technical solution are: by setting the buckle plate with a handle opening, it is convenient for the operator to pull down the sliding buckle plate, and the structural design is reasonable. Attached Figure Description

Detailed Implementation

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0025] Please see Figures 1 to 5 As shown, a rail connector for a circuit breaker includes a sliding fastener 1, a mounting base 2, and an elastic element 3. The sliding fastener 1 slides on the front side of the mounting base 2 via the elastic element 3.

[0026] In this embodiment, the sliding buckle 1 includes a buckle body 4. Two first side plates 5 are provided on the rear side of the buckle body 4. The two first side plates 5 are vertically aligned and flush. More specifically, the length of the first side plates 5 is the same as the length of the buckle body 4. A first locking block 6 is formed at the upper end of each first side plate 5. The first locking block 6 is used to cooperate with the guide rail. The mounting base 2 includes a base body 7 and a base fixing part 8 provided at the upper and lower ends of the base body 7. The first side plates 5 are supported and cooperate with the front side of the base body 7. Therefore, the first side plates 5 also have the function of supporting sliding, making the sliding buckle 1 highly stable and with a reasonable and simple structural design. Two second side plates 9 are provided on the upper side of the front side of the base body 7. The two second side plates 9 are vertically aligned and flush. More specifically, the second side plates 9 are provided at the upper ends of the front side of the base body 7, and the two second side plates 9 are positioned opposite the two first side plates 5. On the lower side of the second side plate 9, there are second locking blocks 10. The second locking blocks 10 are used to cooperate with the guide rail. More specifically, since the first side plate 5 and the second side plate 9 are staggered, the corresponding first locking blocks 6 and second locking blocks 10 are also staggered. With this arrangement, the first locking blocks 6 and second locking blocks 10 will have a better fixing effect on the guide rail. On the lower side of the front side of the base body 7, there are also two inverted L-shaped first guide pressure feet 11. The first guide pressure feet 11 are arranged facing each other. The first guide pressure feet 11 slide and contact with the buckle body 4. That is to say, the vertical part of the first guide pressure foot 11 will form a sliding contact limit with the side wall of the first side plate 5, and the horizontal part of the first guide pressure foot 11 will form a sliding contact limit with the front side of the buckle body 4. In this way, the purpose of reliable sliding is achieved, and the sliding buckle 1 cannot be directly removed from the front side of the mounting base 2, but can only move along the front side of the base body 7.

[0027] In this embodiment, the base body 7 is also provided with two support plates 12, which are set to support the bottom surface of the circuit breaker. The base fixing part 8 is attached to the bottom surface of the circuit breaker and is provided with a connecting hole 13 for screws to pass through. With the base fixing parts 8 at the upper and lower ends of the base body 7, during installation, it is only necessary to pass the screw through the circuit breaker and connect it with the connecting hole 13. Therefore, the guide rail connector can be easily installed on the back of the circuit breaker. At the same time, by setting two support plates 12 on the base body 7, the support plates 12 support the bottom surface of the circuit breaker, thereby increasing the strength of the base body 7 and ensuring the reliability of use.

[0028] In this embodiment, one end of the elastic element 3 is connected to the main body 4 of the buckle plate, and the other end of the elastic element 3 is connected to the main body 7 of the base. The first locking block 6 cooperates with the second locking block 1 through the elastic element 3 to fix the guide rail connector to the guide rail.

[0029] In the above scheme, the guide rail connector is fixed to the guide rail by combining the elastic element 3, the first locking block 6 on the first side plate 5, the second locking block 10 on the second side plate 9, and the two inverted L-shaped first guide pressure feet 11. This guide rail connector is convenient and labor-saving to operate when disassembling and installing electrical equipment. Only the sliding plate buckle 1 is needed to complete the locking or unlocking with the guide rail. More specifically, when disassembly is required, the sliding plate buckle 1 is pulled down to release the first locking block 6 from the guide rail, thereby removing the circuit breaker. When fixing is required, the sliding plate buckle 1 is also pulled down first. After the guide rail connector is placed in place, the sliding plate buckle 1 is released. Under the action of the elastic element 3, the sliding plate buckle 1 is reset so that the first locking block 6 and the second locking block 10 fix the guide rail. Therefore, the guide rail connector with the above structure has the characteristics of reasonable overall structural design, convenient installation and disassembly, and stable fixing effect.

[0030] In this embodiment, the base body 7 is also provided with two inverted L-shaped second guide feet 14. The second guide feet 14 are arranged facing each other and located below the first guide foot 11. The second guide feet 14 slide and contact with the buckle body 4. That is, the vertical part of the second guide foot 14 can form a sliding contact limit with the side wall of the second side plate 9, and the horizontal part of the second guide foot 14 can form a sliding contact limit with the front side of the buckle body 4. This method further improves the sliding reliability. The above structure, by providing two inverted L-shaped second guide feet 14 facing each other on the base body 7, together with the first guide foot 11, makes the sliding buckle 1 more stable. At the same time, the first guide foot 11 and the second guide foot 14 are also easy to form, and the structural design is reasonable.

[0031] Of course, the sliding contact between the second guide foot 14 and the sliding buckle 1 can also be achieved in another way. More specifically, a third side plate 15 is vertically connected at the corresponding position of the first side plate 5, and the second guide foot 14 and the third side plate 15 slide in contact. That is, the vertical part of the second guide foot 14 forms a sliding contact limit with the side wall of the third side plate 15, and the horizontal part of the second guide foot 14 forms a sliding contact limit with the front side of the third side plate 15.

[0032] In the above embodiments, the third side plate 15 is also provided with a limiting foot 16. The limiting foot 16 is positioned below the second guide foot 14. The limiting foot 16 is used to cooperate with the second guide foot 14 to limit the sliding buckle 1. By providing the third side plate 15 with the limiting foot 16, the mating position of the sliding buckle 1 on the mounting base 2 is ensured, and the phenomenon of the sliding buckle 1 detaching is avoided. This makes the installation stability of the elastic element 3 that connects the sliding buckle 1 and the mounting base 2 higher, and the use of the guide rail connector more reasonable.

[0033] In the above embodiment, the bottom wall of the first locking block 6 forms an inclined plane with an angle of A with the base body 7, where the angle of A ranges from 5° to 9°. The bottom wall of the second locking block 10 forms an inclined plane with an angle of B with the base body 7, where the angle of B ranges from 35° to 41°. More specifically, the angle of A is 7° and the angle of B is 38°. Setting the bottom wall of the first locking block 6 as an inclined plane with angle A and the bottom wall of the second locking block 10 as an inclined plane with angle B helps to easily lock the first locking block 6 and the second locking block 10 onto the guide rail. Therefore, the sliding buckle 1 will be smoothly fastened to the guide rail. After multiple experiments, the fit of the above two angle ranges is the best and the structural design is reasonable.

[0034] In the above embodiment, since the second guide foot 14 forms a sliding contact with the third side plate 15, a first stop 17 is provided on the rear side of the main body 4 of the buckle plate, and a second stop 18 is provided on the front side of the main body 7 of the base. The second stop 18 is positioned directly below the first stop 17. A first mounting post 19 located at the center line is provided on the lower side of the first stop 17, and a second mounting post 20 located at the center line is provided on the upper side of the second stop 18. The elastic element 3 can be a spring. One end of the elastic element 3 is sleeved on the first mounting post 17, and the other end of the elastic element 3 is sleeved on the second mounting post 20. By setting the first stop 17 with the first mounting post 17 and the second stop 18 with the second mounting post 20, the elastic element 3 is firmly fixed, so that the elastic element 3 can effectively provide elastic force for the sliding buckle plate 1. The structural design is reasonable, simple and effective. Of course, a tension spring structure can also be used. More specifically, in this structure, the second stop 18 will be positioned directly above the first stop 16.

[0035] In the above embodiments, an installation perforation is also formed on the main body 4 of the buckle plate, through which the elastic member 3 can be installed on the first mounting post 17 of the first stop 17 and the second mounting post 20 of the second stop 18.

[0036] In the above embodiment, two fourth side plates 21 are provided on the lower front side of the base body 7. The two fourth side plates 21 are vertical and flush. The fourth side plates 21 and the second side plate 9 cooperate to form a positioning groove on the base body 7. The positioning groove is used to cooperate with the guide rail. By setting the fourth side plates 21, the fourth side plates 21 and the first side plates 21 form a positioning groove on the base body 7. During installation, the guide rail connector with electrical equipment can be quickly and accurately placed on the guide rail through the positioning groove. The structural design is more reasonable.

[0037] In the above embodiments, the sliding buckle 1 also includes a buckle handle 22, which is located on the lower side of the buckle body 4. The buckle handle 22 is provided with a handle opening 23. By providing a buckle handle 22 with a handle opening 23, it is convenient for the operator to pull down the sliding buckle 1. The structural design is reasonable.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
