DETAILED DESCRIPTION

[0024] In order to achieve the purpose of increasing the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits, the present application provides an electromagnetic relay, the relay 1 comprising a shell 11 and a plurality of plug-in end pieces 12 arranged on one side of the shell 11, the plug-in end pieces 12 being connected to the access control components in the shell 11 through conductive pieces.

[0025] The specific embodiments of the present application are described below.

[0026] Referring to Figures 4-6 , an embodiment of the electromagnetic relay provided by the present application is described, which controls the conduction or disconnection of multiple circuits and increases the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits:

[0027] The access control components of the present application include a main controller 31 and a plurality of secondary controllers 41.

[0028] The main controller 31 is rotatably installed inside the shell 11, and the main controller 31 is connected to the plug-in end piece 12 located in the middle through a conductive piece. A plurality of secondary controllers 41 are installed inside the shell 11, and the conductive end piece I 43 on the secondary controller 41 is connected to the plug-in end piece 12 located at the edge through a conductive piece. The conductive handle 32 on the side of the main controller 31 can abut against the conductive end piece I 43. The conductive piece is embedded and installed in the shell 11.

[0029] Among them, the secondary controller 41 can be directly fixedly installed inside the shell 11. At this time, by controlling the rotation of the main controller 31, the plurality of conductive handles 32 on the side of the main controller 31 are respectively connected to or disconnected from the position corresponding conductive end piece I 43, thereby realizing the control of the conduction or disconnection of multiple circuits and increasing the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits.

[0030] Referring to Figures 4-5 , Figure 8 , and Figure 10 , an embodiment of the electromagnetic relay provided by the present application is described, which controls the rotation of the main controller 31:

[0031] The top of the outer casing 11 of this application is detachably and fixedly connected to a cover 51, and an electromagnetic control component II 54 is installed at the bottom of the cover 51. A sliding column 55 is fixedly installed at the other end of the electromagnetic control component II 54, and the sliding column 55 is slidably connected to the slot arm 35 inside the main controller 31.

[0032] The electromagnetic control component II 54 is extended and retracted, which drives the slide column 55 to move, controls the rotation of the main controller 31, and controls the conduction or disconnection of multiple circuits. During this process, the slide column 55 slides within the slot arm 35.

[0033] Reference Figures 5-9 The following illustration shows an embodiment of the electromagnetic relay provided by the present invention, in which the main controller 31 is connected to the conductive terminal piece I 43 via the conductive terminal piece II 34:

[0034] The main controller 31 of this application has a conductive ring 33 embedded in it. The inner wall of the conductive ring 33 abuts against the plug-in terminal 12 located in the middle through a conductive plate. Multiple conductive terminal plates II 34 are fixedly installed on the side of the conductive ring 33.

[0035] The conductive terminal piece II 34 extends through the main controller 31 and the conductive handle 32 and extends outward from the conductive handle 32, so that the plug-in terminal piece 12 located in the middle can abut against the conductive terminal piece I 43 on the secondary controller 41 through multiple conductive terminal pieces II 34, so that the plug-in terminal piece 12 located in the middle can conduct with multiple plug-in terminal pieces 12 at the same time on the edge, so that multiple circuits can conduct simultaneously.

[0036] Reference Figures 5-6 The illustration shows an embodiment of the electromagnetic relay provided by the present invention, which switches the circuit corresponding to a single group of conductive terminal piece I43 to increase the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits:

[0037] A conductive terminal piece I43 can be installed on each side of the secondary controller 41. Each conductive terminal piece I43 is individually connected to the plug-in terminal piece 12 through a conductive piece. Multiple conductive terminal pieces I43 are divided into two groups according to their positions on the left and right sides of the secondary controller 41. By rotating the main controller 31, the circuit corresponding to a single group of conductive terminal pieces I43 is switched to conduct, thereby increasing the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits.

[0038] The conductive end piece I 43 is connected to the secondary controller 41 through the elastic pad 42, which increases the rotation range of the main controller 31 and increases the stability of the circuit corresponding to the conductive end piece I 43 that controls a single group.

[0039] Reference Figure 7The illustration shows an embodiment of the electromagnetic relay provided by the present invention, which improves the installation method of the secondary controller 41, thereby enabling the control of the conduction or disconnection of a specified circuit and further increasing the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits:

[0040] The installation method of the secondary controller 41 in this application is improved by rotating the secondary controller 41 in the rotating seat 13 on the upper side of the bottom of the housing 11. The bottom of the secondary controller 41 is provided with a control terminal 44, and an electromagnetic control component I 14 is installed between the rotating seat 13 and the control terminal 44.

[0041] The two ends of the electromagnetic control component I14 are rotatably connected to the rotating base 13 and the control end 44, respectively.

[0042] The extension and retraction of the electromagnetic control component I14 causes the auxiliary controller 41 to rotate, preventing the conductive end piece I43 on its side from contacting the conductive end piece II34 on the main controller 31. This allows the designated circuit to be turned on or off, further increasing the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits.

[0043] Reference Figures 6-8 and Figure 10 The illustration shows an embodiment of the electromagnetic relay provided by the present invention, which improves the structure of the conductive handle 32 so that both sides of the conductive end piece II 34 can simultaneously abut against the conductive end pieces I 43 on both sides, further increasing the efficiency of the electromagnetic controller in simultaneously controlling multiple circuits:

[0044] The structure of the conductive handle 32 in this application is improved. The conductive handle 32 is set to have a tapered structure with the width gradually decreasing from bottom to top. The side plane of the conductive handle 32 is set parallel to the inner side of the conductive end piece I43.

[0045] The main controller 31 is vertically slidably installed inside the conductive platform on the upper side of the bottom of the housing 11. When the main controller 31 is raised, both sides of the conductive end piece II 34 simultaneously come into contact with the conductive end pieces I 43 on both sides, further increasing the efficiency of the electromagnetic controller in controlling multiple circuits simultaneously.

[0046] An electromagnetic control component Ⅲ53 is installed between the cover 51 and the top middle side of the main controller 31. The extension and retraction of the electromagnetic control component Ⅲ53 is controlled to lift the main controller 31.

[0047] Reference Figure 10 The illustration shows an embodiment of the electromagnetic relay provided by the present invention, which switches the conduction of a specified circuit by rotating the manual control base 52, thereby maintaining the ability to simultaneously control multiple circuits:

[0048] The manual control seat 52 is rotatably mounted on the middle of the cover 51 of this application, and the manual control seat 52 and the cover 51 can be connected by threaded connection.

[0049] Electromagnetic control component III 53 and electromagnetic control component II 54 are connected to the bottom of cover 51 via manual control base 52. When the secondary controller 41 is directly fixedly installed inside the housing 11, even if electromagnetic control component III 53 and electromagnetic control component II 54 malfunction, the specified circuit can be switched on by rotating the manual control base 52, thus maintaining the ability to control multiple circuits simultaneously.

[0050] Reference Figure 7 and Figure 10 The diagram illustrates the specific structure of the electromagnetic control component used in the electromagnetic relay provided by this invention:

[0051] The electromagnetic control component I 14, electromagnetic control component III 53, and electromagnetic control component II 54 of this application have the same structure, specifically:

[0052] The main body of the electromagnetic control component consists of a sleeve and a sliding column. An electromagnet is installed inside the sleeve, a magnetic plate is installed at the end of the sliding column inside the sleeve, and a positioning spring is installed at the end of the sliding column outside the sleeve.

[0053] When not in use, the positioning spring moves the slide block to its initial position inside the sleeve. When the electromagnet is activated, the magnetic coupling force between the electromagnet and the magnetic plate moves the slide block away from its initial position inside the sleeve, thus connecting and disconnecting the circuit.

[0054] Among them, the positioning springs on electromagnetic control component I14, electromagnetic control component III53 and electromagnetic control component II54 are tension spring, spring I and spring II, respectively.

[0055] Reference Figures 1-4 The following describes the specific steps for manufacturing the electromagnetic relay provided by the present invention:

[0056] Step 1: Install multiple plug-in terminals 12 into the slots 22 on the assembly base 21;

[0057] Step 2: Install the main controller 31 and multiple secondary controllers 41 inside the housing 11;

[0058] Step 3: Install the cover 51 on the top of the outer shell 11 and place it on the upper side of the assembly base 21;

[0059] Step 4: Press the outer casing 11 against the slot 22 so that the plug-in terminal 12 is inserted into the outer casing 11.

[0060] Multiple guide posts 23 are fixedly installed on the assembly base 21 of this application. Positioning sleeves 24 are slidably installed on the guide posts 23. The inner wall of the positioning sleeve 24 can abut against the outer side of the outer shell 11 so as to stably place the outer shell 11 inside the positioning sleeve 24.

[0061] Among them, the positioning sleeve 24 is slidably installed with fastening arms 25 on both sides, and the fastening arms 25 are fixedly installed with finger sleeves 26 on the outside. The lower top of the fastening arms 25 can abut against the top of the cover 51.

[0062] Insert your finger into the finger sleeve 26 and move the two latching arms 25 so that the latching arms 25 on both sides abut against the top sides of the cover 51 respectively. Then, control the latching arms 25 to move down and insert the cover 51 into the housing 11. At the same time, insert the plug-in terminal piece 12 into the housing 11 to complete the assembly and installation of the relay 1.
