Description

Technical Field

[0001] The utility model belongs to the field of solid-state relays, and in particular relates to a solid-state relay which is easy to install. Background Art

[0002] Solid-state relays are contactless switches composed of microelectronic circuits, discrete electronic devices, and power electronic devices. Isolation devices are used to isolate the control end from the load end. The input end of the solid-state relay uses a tiny control signal to directly drive a large current load.

[0003] A Chinese patent with publication number CN219575510U discloses a solid-state relay, including a heat sink, a housing and a main circuit board, wherein the housing is fixedly mounted on one side of the heat sink, the main circuit board is located inside the housing, a transistor is mounted on the side of the main circuit board close to the heat sink, a first insulating tape is fixedly mounted on the side of the heat sink close to the main circuit board, and the heat sink is attached to the first insulating tape. Although the solid-state relay has the effect of facilitating heat conduction from the heat sink to the heat sink, the first insulating tape and the transistor are installed between the heat sink and the main circuit board. The presence of the first insulating tape and the transistor causes the heat sink and the main circuit to be unevenly installed, with gaps and poor heat dissipation caused by conduction of multiple layers of medium, and the heat sink needs to be installed on a matching rail and cannot adapt to rails of different sizes.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0026] See also Figure 1-5 As shown, in this embodiment, a solid-state relay that is easy to install is provided, including: a solid-state relay body 1 and a concave fixing seat 4, a heat sink 2 is installed on the lower side of the solid-state relay body 1, a mounting plate 3 is installed on the lower side of the heat sink 2, two guide rail buckles 7 are elastically and slidably matched on the lower side of the mounting plate 3, a relative movement component 10 connected to the two guide rail buckles 7 is installed in the mounting plate 3, a pressing rod 8 that is matched with the relative movement component 10 is slidably matched on one side of the mounting plate 3, two tooth plates 9 are elastically and slidably matched on both sides of the mounting plate 3, a transmission component 15 that is respectively matched with the two tooth plates 9 is installed in the mounting plate 3, and the transmission component 15 is connected to the pressing rod 8;

[0027] A guide rail 5 matching with two guide rail buckles 7 is mounted on the upper side of the concave fixing seat 4 , and a plurality of locking teeth 6 corresponding to the two tooth plates 9 are mounted on the opposite side of the concave fixing seat 4 .

[0028] The application of one aspect of this embodiment is as follows: when in use, the pressing rod 8 is pressed first, and the pressing rod 8 moves to first drive the two tooth plates 9 to contract and disengage the multiple teeth 6 through the two transmission components 15 respectively, and the pressing rod 8 moves and then drives the two guide rail buckles 7 to move relatively outward through the relative movement component 10. When the two guide rail buckles 7 are inserted into the guide rail 5 and moved to a suitable installation position, the pressing rod 8 is released, and the two tooth plates 9 are elastically engaged with the multiple teeth 6, and the two guide rail buckles 7 are elastically fitted on the guide rail 5, so that the solid-state relay body 1 and the heat sink 2 can be fixed on the concave fixing seat 4.

[0029] By designing the solid-state relay body 1 and the heat sink 2 as an integrated structure, the solid-state relay body 1 and the heat sink 2 can be installed flatly without a gap, and there is no medium in the middle to affect the heat dissipation of the solid-state relay body 1, thereby facilitating the improvement of the heat dissipation effect of the heat sink 2 on the solid-state relay body 1;

[0030] By means of the relatively movable assembly 10, the user presses the pressing rod 8 to drive the two guide rail buckles 7 to move relative to each other outwards through the relatively movable assembly 10, so that the two guide rail buckles 7 can be adapted to guide rails 5 of different sizes. When the two guide rail buckles 7 are snapped into the guide rail 5, the pressing rod 8 is released, and the two guide rail buckles 7 are elastically fitted on the guide rail 5, thereby facilitating the installation of the solid-state relay body 1 and the radiator 2. By means of the transmission assembly 15, when the pressing rod 8 is released, the two tooth plates 9 are elastically snapped into engagement with the multiple teeth 6, thereby facilitating the fixing of the solid-state relay body 1 and the radiator 2 on the concave fixing seat 4.

[0031] like Figure 3-4 As shown, placement grooves 12 are respectively provided on both sides of the mounting plate 3 of this embodiment, and the two tooth plates 9 are respectively slidably fitted in the two placement grooves 12, a fixing rod 14 is installed on one side of the tooth plate 9, and an elastic telescopic rod 13 is installed between the fixing rod 14 and the placement groove 12, and the transmission assembly 15 is located between the fixing rod 14 and the pressing rod 8;

[0032] Specifically, the specific structure of the transmission assembly 15 includes: an L-shaped rod 1501 that slides in the placement groove 12 and is fixedly connected to the pressing rod 8, an inclined groove 1502 opened on one side of the fixed rod 14, and a chamfer provided at one end of the L-shaped rod 1501 and connected to the inclined surface of the inclined groove 1502.

[0033] Through the transmission assembly 15, the user can press the pressing rod 8, and the pressing rod 8 moves to drive the L-shaped rod 1501 to move. The L-shaped rod 1501 moves to chamfer the inclined surface of the extruded inclined groove 1502 to drive the fixing rod 14 to move. The fixing rod 14 moves to drive the tooth plate 9 to move. The tooth plate 9 moves back into the placement groove 12 to release the engagement with the multiple teeth 6. When the two guide rail buckles 7 are inserted into the guide rail 5 and moved to a suitable installation position, the pressing rod 8 is released, and the two tooth plates 9 are automatically engaged with the multiple teeth 6 through the elastic force of the elastic telescopic rod 13, thereby facilitating the fixing of the solid-state relay body 1 and the heat sink 2 on the concave fixing seat 4.

[0034] like Figure 3 As shown, two grooves 16 are provided on the lower side of the mounting plate 3 of this embodiment, and the two guide rail buckles 7 are respectively slidably fitted in the two grooves 16. An inner cavity 11 connected to the two grooves 16 is provided in the mounting plate 3, and the relative moving assembly 10 is located in the inner cavity 11;

[0035] like Figure 5 As shown, specifically, the specific structure of the relative moving component 10 includes: a sealing cylinder 1001 installed in the inner cavity 11, a first sealing plug 1002 and two opposite second sealing plugs 1003 slidingly fitted in the sealing cylinder 1001, an elastic member 1005 installed between the second sealing plugs 1003, a connecting rod 1004 installed on one side of the second sealing plug 1003 and fixedly connected to the guide rail buckle 7, and one end of the pressing rod 8 is fixedly connected to one side of the first sealing plug 1002; the sealing cylinder 1001 is a convex structure, wherein the elastic member 1005 can be a spring or an elastic telescopic rod in the prior art.

[0036] By setting the relative movement component 10, the user can press the pressing rod 8, and the pressing rod 8 moves to drive the first sealing plug 1002 to move in the sealing cylinder 1001 and squeeze the two second sealing plugs 1003. The two second sealing plugs 1003 in the sealing cylinder 1001 move relative to each other due to the compression of the atmosphere. The relative movement of the two second sealing plugs 1003 drives the two connecting rods 1004 to move relative to each other. The relative movement of the two connecting rods 1004 drives the two guide rail buckles 7 to move relative to each other outward. When the two guide rail buckles 7 are inserted into the guide rail 5 and moved to a suitable installation position, the pressing rod 8 is released, and the two guide rail buckles 7 are reset and fitted on the guide rail 5 by the elastic force of the elastic member 1005, thereby facilitating the installation of the solid-state relay body 1 and the heat sink 2.
