DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0024] The installation structure of a miniature circuit breaker provided in the embodiment of the present utility model is as follows Figures 1 to 5 As shown, it includes a circuit breaker body 1, a fixing bayonet 11 is provided at the bottom of the circuit breaker body 1, and a limit stop bar 12 is formed at one end of the fixing bayonet 11 along the width direction of the circuit breaker body 1. A positioning buckle 13 is provided on the limit stop bar 12, and a hook is provided at the end of the positioning buckle 13. A side opening 14 is provided on the other end of the fixing bayonet 11 opposite to the limit stop bar 12. The side opening 14 is for the connecting piece 3 to be laterally inserted into the fixing bayonet 11 and to be abutted against the limit stop bar 12 when the connecting piece 3 is installed in place; oppositely arranged card platforms 15 are provided on both sides of the fixing bayonet 11 in the length direction of the circuit breaker body 1, and the card platforms 15 are used to be clamped with the two sides of the connecting piece 3.

[0025] Reference Attachment Figure 2 、 3, also includes a connecting rod 2, a connecting piece 3 and two connecting rails 4, the connecting rod 2 connects and fixes the two connecting rails 4, and the connecting rod is fixedly connected to the external device during installation; a limited slide groove 41 is formed on the connecting rail 4, and an elastic piece 42 is provided on the connecting rail 4, one end of the elastic piece 42 is connected to the connecting rail 4, and the other end moves in the limited slide groove 41, an elastic groove 44 is formed between the elastic piece 42 and the connecting rail 4, and the elastic groove 44 is connected to the limited slide groove 41. A limited baffle 6 is provided at both ends of the connecting rail 4, the limited baffle 6 is connected to the connecting rail 4 and closes the limited slide groove 41 to prevent the circuit breaker body 1 from escaping from the limited slide groove 41, and the limited baffle 6 can be fixed by bolts when the circuit breaker needs to be removed. By adopting the connecting rail 4 for installation, after the connecting rail is installed, the subsequent installation of the circuit breaker only needs to fix it on the connecting rail 4, and no drilling is required.

[0026] Reference Attachment Figure 4 The connecting piece 3 is provided with a fixing section 32, and a limiting card hole 35 that cooperates with the hook is provided on the fixing section 32. The fixing section 32 is in an inverted convex shape, and the fixing section 32 is slidably fixed to the fixing bayonet 11. During installation, the hook on the positioning buckle 13 is engaged in the limiting card hole 35, and the limiting stop bar 12 can fix and limit the connecting piece 3. The connecting piece 3 is formed with a card-mounting end 31, and a connecting section 33 connecting the fixing section 32 and the card-mounting end 31 is also formed on the connecting piece 3. The connecting section 33 cooperates with the circuit breaker body 1 to better fix it in the fixing bayonet 11 to ensure the fixing strength.

[0027] A latching edge 34 is protruded from the mounting end 31 and arranged along its length. After the connecting piece 3 is fixed to the circuit breaker body 1, the circuit breaker body 1 is pressed toward the connecting track 4 so that the latching edge 34 is latched into the limiting slide groove 41 to complete the installation of the circuit breaker. When the latching edge 34 is latched into the limiting slide groove 41, the elastic piece 42 will deform, causing the elastic groove 44 to become smaller. When the latching edge 34 is latched to the bottom, the elastic piece 42 returns to its original position to prevent the latching edge 34 from detaching. The connecting piece 3 can be made of aluminum alloy profile, which is strong and durable and can be cut to the corresponding length as needed. During installation, it is only necessary to latch the connecting piece 3 into the bottom of the circuit breaker body and then latch it to the connecting track 4.
