Description

Technical Field

[0001] This utility model relates to the field of hanging ornament technology, and in particular to a button switch. Background Technology

[0002] A push-button switch is a switch that uses a button to actuate a transmission mechanism, causing the moving contact to connect or disconnect with the stationary contact, thus switching the circuit. Push-button switches are simple in structure and widely used control electrical appliances. In electrical automatic control circuits, they are used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

[0003] According to existing technology, there is a push-button control switch, with publication number CN213242345U. The lower housing also has a lower mounting shell, which is installed on the upper mounting shell by a first locking pin. After installation, the lower mounting shell abuts against the lower housing, and there is no extra space between the bottom surface of the lower mounting shell and the inner bottom surface of the lower housing. This means that the cable can only be arranged between the outer side of the lower mounting shell and the inner side wall of the lower housing. As a result, the outer side of the lower mounting shell and the inner side wall of the lower housing will not contact each other. The lower housing has low strength, and the cable installation position is fixed. The lower housing needs to be positioned in a certain position to arrange the cable, which makes assembly inconvenient. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Figure 1 This is a front view of a push-button switch according to this utility model, as shown below. Figure 1In the illustrated embodiment, this utility model provides a push-button switch, including a housing 1. A limiting part 2 is provided inside the housing 1, located at the lower end of the housing 1. A stationary contact 3 and a moving contact 4 are both located between the top surface of the housing 1 and the limiting part 2. The limiting part 2 lowers the stationary contact 3 and the moving contact 4. The limiting part 2 has a first end and a second end along the radial direction of the limiting part 2, which respectively abut against the inner wall of the housing 1. A first space 5 for arranging a first cable is provided between the limiting part 2 and the inner bottom surface of the housing 1. Since both the first and second ends of the limiting part 2 abut against the inner wall of the housing 1, the housing 1 is less prone to deformation when subjected to radial force, resulting in high housing strength. Furthermore, the first space 5 between the limiting part 2 and the inner bottom surface of the housing 1 provides sufficient space for arranging the first cable, allowing the cable to be placed at any position without requiring the housing 1 to be positioned in a specific location, thus facilitating assembly.

[0021] Figure 2 This is a front view of a push-button switch according to this utility model. Figure 3 This is a perspective view of the lower housing and limiting part of a push-button switch according to this utility model. Figure 4 This is a perspective view of a push-button switch of this utility model without its upper housing, as shown below. Figure 2 , 3 In the embodiments shown in Figure 4, at least one of the inner sidewalls of the housing 1 is provided with a positioning groove 6, and the limiting part 2 is engaged in the positioning groove 6, so that the limiting part 2 can be fixed to the inner sidewall of the housing 1. Specifically, both inner sidewalls of the housing 1 are provided with positioning grooves 6, and the first end and the second end of the limiting part 2 are respectively fixed in the positioning grooves 6, so that the limiting part 2 is more stable in the housing 1.

[0022] Furthermore, the limiting part 2 is provided with a positioning protrusion 210 protruding from the outer side of the limiting part 2 in the direction toward the positioning groove 6. The positioning protrusion 210 is engaged in the positioning groove 6, which facilitates fixing the limiting part 2 to the inner side wall of the housing 1. Specifically, the positioning groove 6 and the positioning protrusion 210 correspond one-to-one. The positioning protrusion 210 is not easy to shift in the positioning groove 6, and the reliability is high.

[0023] As one embodiment, the housing 1 includes a first housing 110 and a second housing 120, which are joined together by bolts. A positioning groove 6 is provided in the second housing 120 and extends through the second housing 120 in the direction toward the first housing 110. In this way, the limiting part 2 can be locked in the positioning groove 6 from top to bottom, which is convenient for installation.

[0024] As one embodiment, the movable contact 4 is circular in shape, and a guide groove 7 is provided between the top surface of the housing 1 and the limiting part 2 to guide the movable contact 4. Since the movable contact 4 is circular, the guide groove 7 is also circular. This way, the movable contact 4 can be installed without having to position the guide groove 7 at a specific angle, making assembly convenient.

[0025] Specifically, the housing 1 contains two stationary contacts 4 and one moving contact 5. A first cable is routed through a first space 5 onto one of the stationary contacts 4, and a second cable is routed directly onto the other stationary contact 4. The first cable and the second cable are electrically connected to the stationary contacts 4 respectively.

[0026] Specifically, the limiting part 2 is a plate that serves as a lower limit for the stationary contact piece 4 and the moving contact piece 5.

[0027] The principle of this utility model is that the first and second ends of the limiting part 2 abut against the inner side wall of the housing 1, so that the housing 1 is not easily deformed when subjected to radial force, and the housing 1 has high strength; and there is a first space 5 between the limiting part 2 and the inner bottom surface of the housing 1 for arranging the first cable. The first cable can be arranged at any position in the first space 5, without needing to place the housing 1 in a specific position, which makes assembly convenient.

[0028] Working principle: During assembly, first place the first cable in the first space 5, then put the limiting part 2 into the positioning groove 6, then connect the first cable and the second cable to the stationary contact piece 4 respectively, and finally install the first housing 110 on the second housing 120. At this time, the button together with the moving contact piece 5 is installed between the first housing 110 and the limiting part 2. The limiting part 2 has a positioning post 220 for positioning the button.
