Abstract
The utility model provides a solid state relay shell relates to relay technical field, including square casing, the shell top face border is equipped with 4 centrosymmetric installation cavitys, and the installation cavity is square and top side and in the side at casing border for open architecture, the lid is kept off to inside being equipped with of installation cavity, and the height and the degree of depth of keeping off the lid equal with the installation cavity all that it is articulated with installation cavity inner arm to keep off the lid, keeping off lid inside and being equipped with the holding chamber that is used for placing the screw, the holding chamber is equipped with the entrance hole in the side at casing border, the utility model discloses simple structure can prevent effectively that dust and water from leading to the fact the influence to the conductive metal of wiring department, also can the protection against electric shock.
Description
Technical field
This utility model relates to relay technical field, is specifically related to a kind of solid-state relay shell.
Background technology
Solid-state relay contactless is left by what microelectronic circuit, discrete electronic device and power electronic power device formed
Close.The isolation controlling end with load end is achieved with isolating device.The input of solid-state relay, by small control signal, reaches
To directly driving large current load.
It is exposed outside that existing solid-state relay is substantially the position at by wiring, this make wire metals at wiring and
For fixing outside the conducting metal of wire metals is exposed to, As time goes on, dust can be accumulated, it is impossible to waterproof, also may be used
Personnel can be caused to get an electric shock with different conductor and to contact the danger causing short circuit.
In the patent document of publication No. CN204809070U, disclose a kind of solid-state relay with radiator, its
Arrange the solid-state relay of binding post, and radiator including upper surface, solid-state relay is positioned at above radiator and and radiator
Connect as one；Solid-state relay is provided with protection against electric shock structure, and protection against electric shock structure includes that the shell of solid-state relay and correspondence connect
The flip of terminal position, this cover lifting button is located on binding post and and housing hinge；Solid-state relay and heat radiation in this utility model
The structure of device integration, solves the radiator for can not find corresponding specification or can be not added with radiator and cause product excess temperature
The problem lost efficacy, product entirety is the most more attractive；And protection against electric shock structure prevents foreign body entrance shell interior and prevents finger from touching in shell
Live part；But this anti-contact structure causes on the metal at terminal and solid-state relay for fixing the metal of wire also
Be exposed outside, it is impossible to dust and water protection.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of solid-state relay shell, and simple in construction can be effective
Prevent the conducting metal at dust and water butted line from impacting, also can protection against electric shock.
For realizing object above, this utility model is achieved by the following technical programs: outside a kind of solid-state relay
Shell, including square housing, housing end face edge is provided with 4 centrosymmetric installation cavitys, installation cavity be square and top side and
The side of shell border is open architecture；Being provided with door inside installation cavity, the height of door and the degree of depth are all equal with installation cavity, gear
Cover hinged with installation cavity inner webs；Being provided with the containing cavity for placing screws inside door, containing cavity is in the side of shell border
It is provided with entrance hole.
Preferably, entrance hole semicircular in shape.
Preferably, housing also has lock chamber in installation cavity accent side.
Preferably, lock chamber is positioned at the middle of 2 installation cavitys.
Preferably, door and installation cavity medial wall are hinged by hinge.
This utility model provides a kind of solid-state relay shell, simple in construction, passes through installation cavity, door and containing cavity
Structure, can be effectively prevented dust while not affecting wiring and water affects the metal at wiring, increase solid-state relay
Safety；This utility model also can prevent the short circuit that the collision of personnel contact and different electric wire causes；Lock chamber makes solid-state
Fixing of relay is simpler and fixing rear more attractive.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
