DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] See also Figure 1-6 The utility model provides a technical solution: an optocoupler relay, comprising a pad 1, a photocoupler relay body 3 is matched with the top of the pad 1, a fixing block 8 is fixedly connected to the bottom of the photocoupler relay body 3, and the outer surfaces of both sides of the fixing block 8 are respectively provided with limiting grooves 9, and the inner bottom of the pad 1 is provided with a mounting component 2; the mounting component 2 comprises a fixing frame 201, the bottom of the fixing frame 201 is fixedly connected to the inner bottom of the pad 1, and the inner surface of the fixing frame 201 is symmetrically fixedly connected with mounting blocks 202, the inner surfaces of the two mounting blocks 202 are respectively provided with connecting plates 203, and the opposite surfaces of the two connecting plates 203 are respectively symmetrically fixedly connected with fixing rods 205, and the outer surfaces of the plurality of fixing rods 205 are respectively sleeved with springs 206, and the plurality of fixing rods 205 are arranged in two groups, and the opposite surfaces of the two groups of fixing rods 205 are respectively fixedly connected with limiting blocks 207, and the limiting blocks 207 are matched with the limiting grooves 9.

[0018] like Figure 3 As shown, the spring 206 is located between the mounting block 202 and the limit block 207, and the outer surface of the limit block 207 is slidably connected to the inner surface of the fixed frame 201, so that the spring 206 can continue to stretch between the mounting block 202 and the limit block 207 under the elastic reset action, pushing the limit block 207 to contact the limit groove 9, thereby playing a fixing role.

[0019] like Figure 3 As shown, the outer surface of the fixing rod 205 slides through the outer surface of the mounting block 202, and the outer surface of the connecting plate 203 is fixedly connected to the outer rod 204, so that when disassembling, the outer rod 204 is pulled so that the fixing rod 205 slides in the inner wall of the mounting block 202, driving the limit block 207 to retract toward the inner side of the fixed frame 201, thereby facilitating the removal of the optocoupler relay body 3.

[0020] like Figure 4 and Figure 6 As shown, the outer surface of the fixing block 8 fits with the inner surface of the fixing frame 201, and the top of the fixing frame 201 fits with the bottom of the optocoupler relay body 3, so that the optocoupler relay body 3 fits tightly on the top of the fixing frame 201 after installation, and the fixing block 8 fits tightly on the inner surface of the fixing frame 201.

[0021] like Figure 4 and Figure 6As shown, a plurality of slots 7 are equidistantly provided on the top of the pad 1, and a plurality of second pins 10 are equidistantly provided on the bottom of the fixing block 8. The second pins 10 are matched with the slots 7 to facilitate the insertion of the second pins 10 into the slots 7, thus playing a positioning role.

[0022] like Figure 1 and Figure 4-5 As shown, a spring sheet 6 is disposed on the inner surface of the slot 7 , and the spring sheet 6 and the second pin 10 are matched to facilitate the second pin 10 to be inserted into the slot 7 . Under the action of the spring sheet 6 , the spring sheet 6 contacts the second pin 10 .

[0023] like Figure 5 As shown, the outer surface of the spring piece 6 is fixedly connected to a connecting column 5, the outer surface of the connecting column 5 is fixedly passed through the outer surface of the pad 1, and the outer end face of the connecting column 5 is fixedly connected to the first pin 4, so that when the spring piece 6 contacts the second pin 10, it is convenient to connect with the first pin 4 through the connecting column 5, so that the current in the circuit board can be conducted into the optocoupler relay body 3.

[0024] like Figure 1 and 4 As shown, the front surface of the optocoupler relay body 3 is symmetrically provided with a first anti-foolproof mark 11, and the front surface of the pad 1 is symmetrically provided with a second anti-foolproof mark 12. The positions of the first anti-foolproof mark 11 and the second anti-foolproof mark 12 match each other. During installation, the optocoupler relay body 3 is inserted after the positions of the first anti-foolproof mark 11 and the second anti-foolproof mark 12 match each other, which plays an anti-foolproof role and prevents personnel from making the wrong direction during installation, resulting in the inability to connect the optocoupler relay body 3 to the circuit board.

[0025] The method of use and working principle of the device: When the optocoupler relay is used, firstly, the multiple first pins 4 arranged on the outside of the soldering pad 1 are soldered on the circuit board in the correct position, and then the installation direction is determined by the first anti-foolproof mark 11 symmetrically opened on the front surface of the optocoupler relay body 3. After the direction is consistent with the two second anti-foolproof marks 12, the optocoupler relay body 3 is vertically inserted. When the multiple second pins 10 equidistantly arranged at the bottom of the optocoupler relay body 3 near the two side edges are respectively inserted into the multiple slots 7, they will be squeezed and rubbed with the corresponding surfaces of the springs 6 until the bottom of the optocoupler relay body 3 hits the top of the soldering pad 1, and the surface of the second pin 10 is in close contact with the surface of the spring 6. The current in the circuit board can be connected to the optocoupler relay body 3 through the external first pin 4 and the metal connecting column 5. When the outer surface of the fixing block 8 gradually fits the inner surface of the fixing frame 201, the fixing block 8 will respectively hit the two limit blocks 207 , and after sliding friction with it, the two limit blocks 207 are forced to move in opposite directions. The two limit blocks 207 push the two sets of fixing rods 205 respectively, so that the multiple springs 206 are deformed and contracted between the two mounting blocks 202 and the two limit blocks 207. After the bottom of the fixing block 8 contacts the inner top of the welding pad 1, the positions of the two limit grooves 9 will be fixed to the positions of the two limit blocks 207, so that when the two limit blocks 207 lack the extrusion of the fixing block 8, under the elastic reset action of the multiple springs 206, they move into the two limit grooves 9 respectively, playing a fixing role. After the optical coupler relay is damaged, it is only necessary to pull the two outer rods 204 respectively, and when the two connecting plates 203 move outward, the two limit blocks 207 are each contracted to the inner side of the fixed frame 201, so that the personnel can quickly remove the damaged optical coupler relay body 3 and replace it, which reduces the replacement steps of the optical coupler relay body 3 and improves the disassembly and assembly efficiency of the optical coupler relay.
