It has an interactive relationship between the control system (also called the input circuit) and the controlled system (also called the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

[0003] However, in the prior art, the outer shell of the traditional relay module is mostly fixed. Therefore, when the outer shell is damaged by external impact and the internal components are intact, when the outer shell needs to be replaced, the traditional outer shell is fixed, so only a new relay module can be replaced, which will increase the production cost.

A spring 8 is fixedly connected to the inner wall of the side plate 2. A sliding ball 9 is fixedly connected to the bottom end of the spring 8. The outer wall of the sliding ball 9 contacts the outer wall of the top of the circuit board 5. Under the elastic action of the spring 8, the sliding ball 9 is forced to slide into the groove on the circuit board 5.

[0035] The quick-connect mechanism 7 includes a fixed shell 71, the inner wall of which is fixedly connected to a fixed claw 74, the inner wall of the top of the fixed shell 71 is slidably connected to a pressing plate 72, the bottom of the pressing plate 72 is fixedly connected to a pressing claw 75, the lower surface of the pressing claw 75 is in contact with the upper surface of the fixed claw 74, the outer wall of the top of the pressing claw 75 is fixedly connected to a tension spring 76, and grooves are provided in the walls of the fixed claw 74 and the pressing claw 75, and are staggered.

[0036] The top end of the tension spring 76 is fixedly connected to the inner wall of the top of the fixed shell 71, and the inner wall of the top of the fixed shell 71 is slidably connected to the fixed plate 78, the outer wall of the bottom of the pressing plate 72 is fixedly connected to the hook plate 77, and the upper surface of the fixed plate 78 is fixedly connected to the release plate 73, and the inner wall of the fixed shell 71 is fixedly connected to the barb 79, and the outer wall of the barb 79 contacts the outer wall of the fixed plate 78, and the outer wall of the barb 79 contacts the outer wall of the bottom of the hook plate 77, a sliding sleeve is fixed to the inner wall of the fixed shell 71, and a sliding column is fixed to the lower surface of the pressing plate 72, so that the sliding column slides in the sliding sleeve to limit the movement trajectory of the pressing plate 72.

[0037] Working principle:

[0038] When in use, the bottom plate 1 is placed at the position to be installed. At this time, the wedge block under the side plate 2 is slid into the groove on the bottom plate 1, forcing the outer wall of the side plate 2 to contact the plate standing up behind the bottom plate 1. At this time, the side plate 2 is installed in place. At this time, the relay body 6 is installed on the circuit board 5, and the circuit board 5 is slid into the groove in the middle of the side plate 2. When the circuit board 5 slides, the sliding ball 9 on the side plate 2 slides on the surface of the circuit board 5. When the groove on the circuit board 5 moves to below the sliding ball 9, a spring 8 is fixed above the sliding ball 9. Therefore, under the elastic action of the spring 8, the spring 8 is forced to drive the sliding ball 9 to slide into the groove on the circuit board 5. At this time, the side plate 2 fixes the circuit board 5 through the sliding ball 9.

[0039] When the circuit board 5 is installed, the upper cover 3 is also slid into the slide groove 22 on the top of the side panel 2, and the outer wall of the upper cover 3 is also slid to the plate erected behind the bottom panel 1. At this time, the upper cover 3 is installed in place, and the sealing plate 4 is slid along the groove on the side panel 2. At this time, the sealing plate 4 contacts the limiting plate 11 on the bottom panel 1, and the sealing plate 4 is pressed until it cannot move. At this time, the sealing plate 4 is installed in place. At this time, the limiting plate 11 on the bottom panel 1 limits the sealing plate 4, and the sealing plate 4 limits the side panel 2. At this time, the outer frame of the relay module is completely installed in place.

[0040] When wiring is required, the protective plate 31 on the upper cover 3 is slid, and a mounting groove 32 is provided on the upper cover 3, so that the quick-connect mechanism 7 inside is exposed, and then the wire is inserted into the quick-connect mechanism 7 through the wiring port 21 on the side plate 2. When the wire is located in the fixed shell 71 in the quick-connect mechanism 7, a downward pressure is applied to the pressing plate 72, forcing the pressing plate 72 to move downward. At this time, the pressing claw 75 is forced to move downward under the drive of the pressing plate 72, and a fixed claw 74 is provided below the pressing claw 75. Therefore, the combination of the fixed claw 74 and the pressing claw 75 can fix the wire.

[0041] At the same time, a hook plate 77 is fixed on the pressing plate 72, so when the pressing plate 72 moves, the hook plate 77 moves downward synchronously, and a barb 79 is fixed in the fixed shell 71, so when the hook plate 77 contacts the barb 79, the pressing plate 72 is continuously driven, forcing the hook plate 77 to hook the barb 79, thereby fixing the pressing plate 72 and the pressing claw 75, so that the wire can be continuously fixed. When the wire needs to be replaced, the release plate 73 is pressed, and the fixing plate 78 is forced to move downward synchronously under the drive of the release plate 73. When the release plate 73 continues to move, the release plate 73 contacts the barb 79, forcing the barb 79 to separate from the hook plate 77. At this time, the pressing plate 72 moves upward under the elastic action of the tension spring 76, so that the pressing plate 72 is reset, and the pressing claw 75 is separated from the fixing claw 74, so that the fixation of the wire is released.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
