Detailed Implementation

[0014] Combination Figures 1 to 5 The auxiliary and separation indicator device of this utility model will be further described.

[0015] A housing structure for an auxiliary and merging / separation indicator device, characterized in that it includes a base shell 1 and a cover plate 2.

[0016] The base shell 1 has a mounting groove 14 with its opening facing left. Multiple locking blocks 11 are located on the outer wall of the mounting groove 14. The side of each locking block 11 facing the groove has an inclined guide surface 111. Multiple elastic buckles 21 corresponding to the locking blocks 11 are located on the inner wall of the cover plate 2. Each elastic buckle 21 has a locking slot 211 for the locking blocks 11 to engage. A cable outlet 13 communicating with the mounting groove 14 is provided on the rear side of the base shell 1. A wire groove 15 is located above the corresponding cable outlet 13 on the base shell 1.

[0017] Specifically, the locking block 11 is a right-angled triangular prism structure, and the inclined surface of the right-angled triangular prism is the guide surface 111 of the locking block 11. During the closing process of the cover plate 2, the end of the elastic buckle 21 away from the cover plate 2 gradually deforms outward under the guidance of the guide surface 111 until it passes the guide surface 111, and then springs back so that the locking block 11 and the latch 211 are just aligned and engaged. When it is necessary to disassemble, the elastic buckle 21 is pulled outward by hand or tool to separate the latch 211 from the locking block 11, so that the cover plate 2 can be disassembled, which has the characteristics of convenient disassembly and assembly.

[0018] The mounting groove 14 includes a swing arm mounting area 141, a micro switch mounting area 142 located behind the swing arm mounting area 141, and a transmission rod groove 143 located below the swing arm mounting area 141. A notch 12 is located at the top of the mounting groove 14, and an extension plate 22 is located at the top of the cover plate 2. The height of the extension plate 22 is less than the depth of the notch 12, so that when the cover plate 2 is closed on the mounting groove 14, an indicator plate groove 16 is formed on the top of the outer casing. This structure allows for the integrated installation of the micro switch 3, swing arm 5, transmission rod 4, and indicator plate 6 in the auxiliary and opening / closing device within the mounting groove 14, realizing the auxiliary switch and contact opening / closing indication functions of the auxiliary and opening / closing device.

[0019] The rear middle portion of the outer casing structure is recessed forward by 20, and a swing arm rear swing support position 173 is formed inside the mounting groove 14. Specifically, near the middle section, the rear groove wall of the mounting groove 14 first extends downward and forward to form an upwardly inclined wall 171, and then bends and extends upward and backward to form a downwardly inclined wall 172. This structure can reduce the volume of the outer casing structure, making it more compact and easier to assemble in a circuit breaker; secondly, the swing arm rear swing support position 173 formed by the extension structure of the rear groove wall of the mounting groove 14, in conjunction with the shape of the swing arm, can limit the range of backward swing of the swing arm, further improving the compactness and rationality of the outer casing structure.

[0020] The rear wall of the mounting groove 14 extends upward and backward to form a downward sloping wall 172, which is also the sloping upper wall of the micro switch mounting area 142. The bottom wall of the mounting groove 14, corresponding to the rear section, is also a sloping structure 174, which is the sloping lower wall of the micro switch mounting area 142. Therefore, the micro switch mounting area 142 is also a sloping structure, so that the micro switch 3 is installed at an angle. The lead end of the micro switch can be tilted upward, so that the micro switch wire 31 can pass through the lead outlet 13 and extend upward into the wire groove 15.

[0021] The wire channel 15 is formed by an arc-shaped rod 7 molded on the base shell 1. Specifically, the lower end of the arc-shaped rod 7 is formed on the base shell 1, i.e., the lower inclined wall 172, and the upper end extends toward the upper inclined wall 171 and separates from the upper inclined wall 171 to form a wire exit outlet 8. In this structure, the wire channel 15 is located in the recessed area on the rear side of the shell structure, which further improves the sophistication of the shell structure; secondly, the wire can pass through the wire channel 15 in the left-right direction, and can also enter and exit the wire channel 15 in the front-back direction, which has the characteristics of convenient wiring.

[0022] The mounting slot 14 has multiple mounting posts 17, the micro switch mounting area 142 has two mounting posts 17 for micro switch mounting, and the bottom of the swing arm mounting area 141 has one mounting post 17 for swing arm swing mounting.

[0023] The bottom of the outer shell structure has a mounting groove 18, and the right side wall of the base shell 1 has a mounting plate 19 with mounting holes. The outer shell structure can be assembled into the circuit breaker by means of the mounting groove 18, the mounting holes and the corresponding bolts.

[0024] In practical use, the cover plate 2 is installed on the base shell 1 through a snap-fit ​​structure, which is convenient to disassemble and assemble; the wire groove can collect and guide the wires extending from the mounting groove 14, which significantly improves the neatness of the wiring of the entire auxiliary and connection / disconnection indicator device; the mounting groove 14 in the outer shell structure can simultaneously accommodate the micro switch 3, swing rod 5, transmission rod 4 and indicator plate 6 in the auxiliary and connection / disconnection indicator device, which is characterized by reasonable arrangement, high integration and simple structure.
