[0035] The present invention discloses a low-voltage intelligent composite switch that is easy to wire and install and is mainly used in scenarios where the installation efficiency of the wiring terminals on the composite switch is low.

[0036] Embodiment 1:

[0037] The following is combined with Figure 1-6 , further details of this application are given.

[0038] The present application embodiment discloses a low-voltage intelligent composite switch that is easy to wire and install. Figure 1 A low-voltage intelligent composite switch that is easy to wire and install includes a housing 1, an input terminal 2 is provided on the upper side of the housing 1, and an output terminal 3 is provided on the lower side. To ensure the heat dissipation effect, a plurality of heat dissipation grooves 101 are provided on the left and right sides of the housing 1, and the heat dissipation grooves 101 are connected to the inner cavity of the housing 1.

[0039] Reference Figure 1Two communication interfaces 4 are provided on the housing 1, and each communication interface 4 is connected to the control board in the housing 1 respectively. The housing 1 is also provided with an insertion slot 5 for inserting a terminal block, and the insertion slot 5 is communicated with the inner cavity of the housing 1, and a terminal block 8 is arranged in the insertion slot 5, and a quick fixing component 9 is arranged at the bottom of the terminal block 8.

[0040] During installation, the composite switch can be connected to an external controller through a communication line, which simplifies the installation process, reduces the complex wiring and connection steps required for traditional terminal blocks, and reduces installation time and labor costs. The communication interface 4 on the composite switch is set to two. During installation, multiple composite switches are connected in series through communication lines and then connected to the external controller, realizing centralized control, simplifying the system's wiring and control logic, and reducing the complexity and cost of the system. In addition, the composite switch also supports traditional contact connection. When the user's controller does not yet support communication line connection, the terminal block is inserted into the insertion slot 5 during use, which is convenient for the user to use in transition before configuration upgrade.

[0041] Reference Figure 1 At least two countersunk holes 102 for mounting bolts are provided through the housing 1. In this embodiment, four countersunk holes 102 are provided.

[0042] Reference Figure 2-3 A hanging groove 13 for being installed on the external guide rail 6 is provided on the back of the shell 1, a clamping groove 61 is provided on the upper end of the external guide rail 6, a clamping block 14 adapted to the clamping groove 61 is fixed on the upper side wall of the hanging groove 13, and a movable space 15 for the external guide rail 6 to pass through is formed between the lower end of the clamping block 14 and the lower side wall of the hanging groove 13, and a push-pull movable component 7 for abutting against the lower side of the external guide rail 6 is provided on the shell 1.

[0043] Reference Figure 2-4 The push-pull movable assembly 7 includes a movable plate 71 and a fixing member 72. The fixing member 72 is fixed on the shell 1. The movable plate 71 is slidably connected to the fixing member 72. Notch grooves 711 are provided on the lower sides of both ends of the movable plate 71. Elastic members are integrally formed on both sides of the upper end of the fixing member 72. The elastic members are arranged in a one-to-one correspondence with the notch grooves 711, and the elastic members abut against the groove walls of the corresponding notch grooves 711.

[0044] Reference Figure 4-6 The elastic member is a spring sheet 73, and a guide curved surface 731 is provided on the opposite side of the two spring sheets 73. When the guide curved surface 731 is compressed, the spring sheets 73 have a tendency to open outward. A push-pull handle 712 is integrally formed at the lower end of the movable plate 71, and a protrusion 713 is integrally formed on the side of the push-pull handle 712 close to the fixed member 72. A sliding groove 721 adapted to the protrusion 713 is provided on the fixed member 72. In this embodiment, the protrusion 713 is dovetail-shaped.

[0045] When the push-pull handle 712 is pulled downward, the movable plate 71 is driven to move downward, so that the external guide rail 6 can pass through the movable space 15 during installation; at the same time, the groove wall of the notch groove 711 squeezes the spring piece 73, so that the spring piece 73 opens outward, and the spring piece 73 stores energy. After the clamping block 14 is clamped into the clamping groove 61 on the external guide rail 6, the push-pull handle 712 is released, and the spring piece 73 releases energy and resets, thereby pushing the movable plate 71 to move upward until the movable plate 71 abuts against the lower side of the external guide rail 6, thereby realizing the limit of the composite switch and improving the installation efficiency of the composite switch.

[0046] In this way, the composite switch can be installed in the electrical cabinet by means of conventional bolt fixing, or can be quickly installed on the external guide rail 6 in the electrical cabinet by means of the clamping block 14 and the push-pull movable assembly 7, and the installation is flexible and convenient.

[0047] Reference Figure 3 When the conventional bolt fixing method is adopted to install the switch in the electrical cabinet, in order to prevent the push-pull movable component 7 on the back of the shell 1 from protruding, causing the back of the shell 1 to be uneven, thereby affecting the fixing effect of the composite switch, a mounting groove 16 is provided on the back of the shell 1, and the push-pull movable component 7 is arranged in the mounting groove 16. Avoidance grooves 161 for the spring 73 to move are provided on both sides of the mounting groove 16.

Under the pull of the tightened spring 1 97, the movable block 96 drives the fixed seat 91 to move quickly on the groove 95, so that the push-pull rod 98 pushes the lower connecting rod 92 connected to the shaft rod 94 to rotate quickly, so that the angle between the lower connecting rod 92 and the upper connecting rod 93 increases, so that the upper connecting rod 93 pushes the terminal 8 on the supporting plate 12 to move upward, and the upward moving terminal 8 drives the connecting piece 1113 to overcome the lateral pulling force and friction force generated by the slider 1114 connected to the spring four 1115, and is lifted and separated from the power connection frame 1111, so that the power connection frame 1111 can no longer generate a current path with the terminal 8, so that the terminal 8 is completely separated from the housing 1.

[0054] The device can monitor the operating status of the terminal block 8 in real time by using the emergency disconnection component 11, so that the device can cut off the power connection between the terminal block 8 and the housing 1 in an emergency, reducing the risk of damage to the terminal block 8 and the line connected to the terminal block 8, reducing the loss of materials such as lines and equipment, and saving costs.
