Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker with a wall connection structure. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time. It is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a release, a housing, etc. When a short circuit occurs, the magnetic field generated by the large current, which is generally 10 to 12 times the current, overcomes the reaction spring, and the release pulls the operating mechanism to operate, causing the switch to trip instantly; when overloaded, the current becomes larger, the heat generation increases, and the bimetallic strip deforms to a certain extent to drive the mechanism to operate. The larger the current, the shorter the operation time.

[0003] Publication (announcement) number: CN218676972U discloses a wall-fixed installation device for a circuit breaker, including a mounting frame, a fixing shell and a protective slot. The fixing shell is movably connected to the middle of the front of the mounting frame, and protective slots are provided through the middle of the front and left and right sides below the fixing shell; the mounting frame includes a suction cup, a slide groove and a slider, the suction cups are fixedly connected to the back of the mounting frame, the slide grooves are embedded in the front of the mounting frame, and the sliders are movably connected in the slide groove; the fixing shell includes a connecting plate and a reinforcement sheet, the connecting plates are fixedly connected to the left and right sides below the fixing shell, and the reinforcement sheets are tightly attached to the upper and lower sides of the middle of the back of the fixing shell by glue. This wall-mounted installation device for a circuit breaker uses a clamping method to fix the circuit breaker to the wall, and the mounting bracket used to provide clamping force for the circuit breaker is an adsorption force generated by a suction cup adsorbed on a transparent tape. However, there are defects, mainly reflected in the tape, because the adhesion provided by the tape is limited, that is, the adhesion will gradually disappear after being damp. After the adhesion gradually disappears, the tape will separate from the wall under the influence of the gravity of the circuit breaker, causing the circuit breaker to detach from the wall. If maintenance is required, the tape needs to be replaced frequently, which is relatively cumbersome. Utility Model Content

[0014] Figure 2 It is a schematic diagram of the explosion structure of the utility model. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] Referring to the accompanying drawings, this circuit breaker with a wall-mounted connection structure includes several assembled circuit breaker bodies 1. The back of the circuit breaker body 1 is provided with a connection groove 11 extending along its width, so as to be connected to a wall mounting member 2 provided on the wall through the connection groove 11. The connection groove 11 is provided with a positioning rod 3 on the circuit breaker body 1. The wall mounting member 2 is provided with a number of positioning holes 4, the same as the number of circuit breaker bodies 1, which are used to define the final connection position of the circuit breaker body 1 on the wall mounting member 2. When the positioning holes 4 are engaged with the positioning rods 3, the circuit breaker body 1 is prevented from being separated from the wall mounting member 2. The wall mounting member 2 is provided with a guide channel 5 connected to the positioning hole 4. The positioning rod 3 reaches the positioning hole 4 through the guide track of the guide channel 5. The principle of the present invention is that the wall mounting part 2 is placed inside by utilizing the connecting groove 11 when the circuit breaker body 1 is mounted on the wall, and when the wall mounting part 2 is placed in the connecting groove 11, the positioning rod 3 is also synchronously entered into the guide channel 5. Considering that the space provided by the connecting groove 11 is limited, the wall mounting part 2 needs to be inserted in an inclined manner during assembly or disassembly, and a gap is formed between the wall mounting part 2 and the bottom surface of the connecting groove 11 after the wall mounting part 2 and the connecting groove 11 are assembled. The gap is used to facilitate the separation of the wall mounting part 2 and the positioning rod 3. The guide channel 5 uses the trajectory provided by itself to guide the positioning rod 3 to reach the positioning hole 4 and combine with it, thereby realizing the assembly of the circuit breaker body 1 and the wall mounting part 2, and then the wall mounting part 2 is set on the wall by bolts to complete the mounting of the circuit breaker body 1 on the wall. This method does not require frequent maintenance to ensure the stability of the circuit breaker body 1 after it is mounted on the wall, as in the prior art.

[0017] The guide channel 5 includes an upper channel 51 and a lower channel 52. The upper channel 51 is arranged on the wall mounting part 2 so that the positioning rod 3 is placed in the upper opening 51-a of the guide channel 5, and the lower channel 52 is connected to the positioning hole 4. Such an arrangement can extend the length of the guide channel 5, which can increase the difficulty of the positioning rod 3 escaping from the guide channel 5. The upper opening 51-a allows the positioning rod 4 to enter the guide channel 5 from top to bottom, so that after the positioning rod 4 reaches the upper opening 51-a, it can be hung on the wall mounting part 2 in a falling manner, so that the circuit breaker body 1 will not be separated from the wall mounting part 2.

[0018] The lower channel 52 is arranged at an angle, and a turning section 53 is provided at the connection between the lower channel 52 and the upper channel 51, which allows the positioning rod 3 to reach the lower channel 52 from the upper channel 51. Such an arrangement can further increase the difficulty of the positioning rod 3 to escape after reaching the positioning hole 4, that is, the turning direction of the turning section 53 is used to change the movement direction of the positioning rod 3 in the guide channel 5, and the inclination is used to match the angle change presented by the turning section 53, and the inclination requires that the circuit breaker body 1 has movement changes in both the horizontal and vertical directions when it is separated from the wall mounting member 2, rather than a single horizontal change. The upper channel 51 is arranged vertically, and is set at 90° to the upper end face of the wall mounting member 2.

[0019] The turning section 53 has a fitting wall 53 - a that can fit onto a portion of the surface of the positioning rod 3 when the positioning rod 3 reaches the turning section 53 , so that the positioning rod 3 is accurately positioned in the turning section 53 to match the accuracy of the positioning rod 3 entering the turning section 53 .

[0020] The positioning rod 3 has an anti-slip block 31. When the positioning rod 3 is placed in the guide channel 5 and the positioning hole 4, the anti-slip block 31 fits against the surface of the wall mounting member 2 to prevent the circuit breaker body 1 and the wall mounting member 2 from separating. The anti-slip block 31 provides a restraining force to prevent the positioning rod 3 from escaping in the front-to-back direction when the positioning rod 3 moves in the guide channel 5. In this way, the positioning rod 3 can ensure a stable connection between the circuit breaker body 1 and the wall mounting member 2 regardless of whether it moves in the guide channel 5 or reaches the positioning hole 4.

[0021] The wall mounting member 2 is configured as a plate-like component, which is bent into two parts, one part is used to form the positioning hole 4 and the guide channel 5, and the other part is used to connect to the wall surface. In this way, the wall mounting member not only has a part connected to the wall, but also has a part for forming the positioning hole 4 and the guide channel 5, and a gap is formed between the part for forming the positioning hole 4 and the guide channel 5 and the wall, and the gap will not interfere with the setting of the anti-slip block 31.

[0022] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
