DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0027] The directional and positional terms used in this invention, such as up, down, front, back, left, right, inside, outside, top, bottom, and side, are merely references to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0028] like Figure 1-5 As shown, a relay socket capable of efficient wiring includes a housing 1, wherein a power conductive component and a load conductive component are provided in the housing 1, wherein the power conductive component includes a first positive plug-in terminal 2, a first negative plug-in terminal 3, and two groups of power line wiring structures electrically connected to the first positive plug-in terminal 2 and the first negative plug-in terminal 3, respectively; two first coil pin jacks 101 are provided on the housing 1 corresponding to the first positive plug-in terminal 2 and the first negative plug-in terminal 3, and two first power wiring holes 102 are provided corresponding to the two groups of power line wiring structures; the power conductive component includes a second positive plug-in terminal 4 electrically connected to the first positive plug-in terminal 2 and / or a second negative plug-in terminal 5 electrically connected to the first negative plug-in terminal 3; and a first shorting pin jack 103 is provided on the housing 1 corresponding to the second positive plug-in terminal 4 and / or the second negative plug-in terminal 5;

[0029] The device also includes a shorting member comprising a conductive body 1101 and at least two shorting pins 1102 fixed to the conductive body 1101. The shorting pins 1102 can be inserted into the first shorting pin receptacle 103 to form a plug-in connection with the second positive plug-in terminal 4 or the second negative plug-in terminal 5. By simultaneously inserting the shorting member into the first shorting pin receptacles of multiple relay sockets, a common cathode or common anode connection can be achieved for multiple relay sockets. This allows one power supply terminal to be connected to the neutral or live wire in common, while the other terminal can then be connected separately. Compared to the prior art method of individually wiring the two-pole power supply wiring structure of each relay socket, this method can save a lot of wiring work and improve wiring efficiency.

[0030] Common cathode and common anode of relays are two different connection methods with different characteristics and application scenarios.

[0031] Common cathode connection: The negative poles of the power supply terminals of multiple relays are connected together and grounded (or connected to a common low-potential point). The control circuit is relatively simple, usually only requiring a control signal source to provide a positive voltage. It is suitable for situations where the control signal source outputs a positive voltage. For the control of multiple relays, it can be achieved through a common neutral terminal, saving wiring and connection costs. Its application scenario: When the controller or logic circuit used outputs a positive voltage signal, the common cathode connection method can be conveniently used to control the relay. At the same time, in some situations where multiple relays need to operate simultaneously and the control signal source is relatively simple, the common cathode connection can simplify the circuit design.

[0032] Common anode connection: The positive terminals of multiple relays are connected together and connected to a common high-potential point (live wire). This is suitable for control signal sources with negative output voltages or active-low voltages. Powering multiple relays from a common high-potential point facilitates power management and wiring. Common anode connection may be more suitable for applications requiring voltage level matching with other circuits. When the controller outputs an active-low signal or a negative voltage signal, a common anode connection allows for direct control of relays. In systems requiring high power stability, a common anode connection provides a reliable power source for the relays from a stable high-potential point.

[0033] Only one second positive plug-in terminal 4 can be provided to achieve quick common anode connection during wiring, or only one second negative plug-in terminal 5 can be provided to achieve quick common cathode connection during wiring, or both the second positive plug-in terminal 4 and the second negative plug-in terminal 5 can be provided. The housing 1 is provided with two corresponding first shorting pin sockets 103, and quick common anode or common cathode connection can be selected on site as needed. In this embodiment, specifically, both the second positive plug-in terminal 4 and the second negative plug-in terminal 5 are provided.

[0034] Furthermore, the first shorting pin jack 103 and the first coil pin jack 101 are located on the same side surface of the housing 1. A guide rail connection structure is also included, and the first shorting pin jack 103 and the first coil pin jack 101 are located on the side surface of the housing 1 away from the guide rail connection structure. In industry, when installing relay sockets, a guide rail member is usually provided, and then several relay sockets are installed on the guide rail member in sequence along the horizontal direction through the guide rail connection structure. At this time, the first shorting pin jack 103 and the first coil pin jack 101 on opposite sides of the guide rail connection structure are facing outward. At this time, the installation of the relay and the installation of the shorting member to achieve common cathode or common anode wiring are more convenient, and subsequent maintenance is easier.

[0035] like Figure 3As shown, the power cord wiring structure includes a wiring board 6 and a spring 7 elastically abutting against the wiring board 6, and is provided with a pressing member 8. The pressing member 8 cooperates with the spring 7 and is provided with a driving part 801 exposed on the surface of the shell 1. Driving the pressing member 8 can move the spring 7 away from the wiring board 6 and form a wiring cavity between the wiring board 6.

[0036] like Figure 4 As shown, a base 9 is fixed in the shell 1, and the base 9 is provided with a power conductive component installation groove 901. The power conductive component is installed in the power conductive component installation groove 901. The upper end of the base 9 is provided with two second coil pin holes 902 corresponding to the first positive plug-in terminal 2 and the first negative plug-in terminal 3, a second power wiring hole 903 is provided in the corresponding wiring cavity, a second short-circuit pin hole 904 is provided corresponding to the second positive plug-in terminal 4 and / or the second negative plug-in terminal 5, and a second through-hole is provided corresponding to the pressing piece 8 for it to pass through. The shell 1 is provided with a first through-hole for the pressing piece 8 to pass through.

[0037] like Figure 5 As shown, the first positive plug-in terminal 2 and the first negative plug-in terminal 3 are integrally connected to the corresponding terminal block 6 via a conductive sheet 10. The second positive plug-in terminal 4 and / or the second negative plug-in terminal 5 are integrally formed on the corresponding conductive sheet 10, and the conductive sheet 10 is stamped with an abutment flap 1001. The power conductive component mounting slot 901 has an installation opening located on the side of the base 9, and the power conductive component is installed in the power conductive component mounting slot 901 through the installation opening. The second coil pin socket 902, the second power connection hole 903, the second shorting pin socket 904, and the second through-hole are all located on the upper surface of the base 9. This arrangement facilitates installation of the power conductive component.

[0038] A limiting protrusion 905 is integrally formed in the power conductive component installation groove 901, and the spring 7 has a bending portion 701 and a fixed portion 702 and a movable portion 703 respectively located on both sides of the bending portion 701. The fixed portion 702 is fixed relative to the base 9, and the movable portion 703 elastically abuts against the terminal block 6; the upper end of the limiting protrusion 905 abuts against the bending portion 701, and a limiting inclined surface retaining wall 906 is provided on the side close to the terminal block 6, and the movable portion 703 can swing between the limiting inclined surface retaining wall 906 and the movable portion 703.

[0039] like Figure 2As shown, the side wall of the conductive body 1101 is provided with a breakaway notch 1103. The length of the conductive body 1101 can be set to be longer. The provision of the breakaway notch 1103 allows wiring personnel to select the appropriate length as needed during on-site wiring. The breakaway notch 1103 can be used to directly break the conductive body 1101 to connect the corresponding number of relay sockets in a common cathode or common anode configuration.
