Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to the housing structure of an auxiliary alarm and opening / closing indicator device. Background Technology

[0002] Molded case circuit breakers (MCCBs) are commonly used in low-voltage power distribution systems as terminal switches or branch switches to provide real-time protection for power lines. To better monitor the operating status of MCCBs, auxiliary switching devices are usually installed. These devices often integrate one or two of the functions of an auxiliary switch, an alarm switch, and a closing / opening indicator to provide signal indications. This allows operators to determine the circuit breaker's operating status during line inspection, maintenance, and line closure, ensuring their safety.

[0003] In existing technologies, the housing structure of auxiliary switching devices typically consists of a housing and a cover plate, which are fixed together by bolts, resulting in inconvenience in disassembly and assembly. Secondly, existing housing structures lack wire positioning mechanisms, leading to complex wiring arrangements within the auxiliary switching device and hindering maintenance by operators. Therefore, the housing structure in existing technologies needs improvement to meet current usage requirements. Utility Model Content

Detailed Implementation

[0011] Combination Figures 1 to 4 The outer shell structure of the auxiliary reporting and separation indicator device of this utility model will be further described.

[0012] A housing structure for an auxiliary reporting and separation indicator device, characterized in that it includes a housing 1 and a cover plate 2.

[0013] The housing 1 has a left mounting groove 11 facing left and a right mounting groove 12 facing right on its left and right sides, respectively. Multiple latches 13 are provided on the walls of both the left and right mounting grooves 11 and 12. Two cover plates 2 are provided, each with a first elastic latch 21 corresponding to the number of latches 13. The two cover plates 2 are assembled onto the slots of the left and right mounting grooves 11 and 12 respectively by engaging the first elastic latches 21 with the latches 13, forming a left chamber and a right chamber on the left and right sides of the housing. A sliding groove 19 is formed on the top of the left chamber. The left mounting groove 11 is used to install the auxiliary micro switch 4 and the auxiliary trigger rod 5 that triggers the auxiliary micro switch 4 in the auxiliary switch. The right mounting groove 12 is used to install the alarm micro switch 6 and the alarm trigger rod 7 that triggers the alarm micro switch 6 in the alarm switch. The sliding groove 19 on the top of the left chamber is used for the sliding cooperation of the indicator plate 3 in the open / closed indicator structure.

[0014] Both the left mounting slot 11 and the right mounting slot 12 have cable outlets 18 at their rear top positions. The housing 1 has two wire grooves 17 distributed to the left and right between the two cable outlets 18. Both wire grooves 17 extend to the left and right, respectively corresponding to the left mounting slot 11 and the right mounting slot 12. The wires 8 coming out of the left mounting slot 11 pass through the left wire groove from left to right and then extend upward. The wires 8 coming out of the right mounting slot 12 pass through the right wire groove 17 from right to left and then extend upward. This wiring structure allows the wires 8 extending from the left mounting slot 11 and the right mounting slot 12 to converge together and then extend upward, which can improve the neatness of the entire wiring.

[0015] To accommodate the dimensional requirements of auxiliary alarm and opening / closing indicator devices when installed in the circuit breaker, the housing 1 also has an intermediate isolation groove 20 located between the left mounting groove 11 and the right mounting groove 12, ensuring stable installation of the housing structure within the circuit breaker. Furthermore, this intermediate isolation groove separates the left mounting groove 11 and the right mounting groove 12, preventing interference between the electrical components within them and facilitating assembly. In practical applications, the size of this intermediate isolation groove can be set according to the actual installation dimensions on the circuit breaker, or the intermediate isolation groove can be omitted altogether.

[0016] The height of the left mounting slot 11 is greater than the height of the right mounting slot 12, which can increase the length of the auxiliary trigger rod 5. There is a notch 14 on the top wall of the left mounting slot 11, and the cover plate 2 corresponding to the left mounting slot 11 has an extension plate 22 extending toward the inside of the notch 14. The slide groove 19 is formed by the extension plate 22 fitting in the notch 14, allowing the indicator plate 3 to slide back and forth on the housing.

[0017] Two arc-shaped guide rods 16 are located between the two cable outlets 18 on the housing 1. The wire groove 17 is formed by one end (rear end) of the arc-shaped guide rod 16 being formed on the housing 1, and the other end (front end) being separated from the housing 1. This structure allows the wire 8 to pass through the wire groove 17 in the left-right direction and also to be removed from the wire groove in the front direction, facilitating wiring and subsequent maintenance. Furthermore, the arc-shaped structure of the guide rod 16 can provide a certain degree of restraint for the wire 8 in the wire groove 17. Specifically, when the wire 8 extends upward through the wire groove 17 and is pulled taut, the front end of the guide rod bends downward to restrain the wire, preventing the wire from easily coming out of the wire groove 17.

[0018] The front and rear side walls of the housing 1 are each provided with a second elastic locking foot 15, which corresponds to the intermediate isolation groove 20.

[0019] In practical use, the outer casing is secured to the circuit breaker by the two front and rear second elastic locking feet 15, so that the auxiliary alarm and opening / closing indicator devices can be used in conjunction with the circuit breaker.

[0020] In the housing structure, the slide groove 19 allows the indicator plate 3 of the opening / closing indicator structure to be installed. The left mounting groove 11 allows the auxiliary micro switch 4 of the auxiliary switch and the auxiliary trigger rod 5 that triggers the switching of the signal of the auxiliary micro switch 4 to be installed. The auxiliary trigger rod 5 is connected to the indicator plate to simultaneously drive the indicator plate 3 to slide. The right mounting groove 12 allows the alarm micro switch 6 of the alarm switch and the alarm trigger rod 7 that triggers the switching of the signal of the alarm micro switch 6 to be installed. Therefore, the housing structure allows the auxiliary switch, alarm switch and opening / closing indicator structure to be integrated and installed, so that the auxiliary alarm and opening / closing indicator device can simultaneously have the functions of an auxiliary switch, an alarm switch and an opening / closing indicator.

[0021] The cover plate 2 is installed on the left mounting slot 11 and the right mounting slot 12 by engaging with the first elastic locking foot 21, which is convenient for disassembly and assembly. Specifically, during installation, the cover plate 2 is directly placed on the opening of the mounting slot. During the closing process, the first elastic locking foot 21 deforms and resets to engage with the locking foot 13. To disassemble, a tool is used to push against the head of the first elastic locking foot 21 through the locking foot 13, causing the first elastic locking foot 21 to deform and the barbed head to disengage from the locking foot 13, so that the cover plate 2 can be removed from the mounting slot.

[0022] The two wire slots 17 can position the wires extending from the left mounting slot 11 and the right mounting slot 12, improving the rationality and neatness of the wiring, and facilitating assembly and subsequent maintenance.
