Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
Encapsulating heat-conducting glue of the existing technology is exposed, pcb board utilization rate is low, can not carry out in order to solve for the utility model
The deficiencies of definition mark production, a kind of solid-state relay of sealing structure is provided, increases setting pedestal, carried out with pedestal and shell
Sealing is realized in cooperation, prevents encapsulating heat-conducting glue exposed, and pedestal can be used for being arranged the definition mark of leading foot, be easy to use；
Error-proof structure can also be set on the base, improve the utilization rate of pcb board.
As shown in Figure 1, Figure 2, Figure 3 shows, the solid-state relay of sealing structure described in the utility model, including shell 10, PCB
Plate 20, pedestal 30, leading foot 40, leading foot 40 and pedestal 30 are integrated the integral structure of injection molding, and leading foot 40 is threaded through
On pedestal 30, i.e., the welding ends of leading foot 40 is located at 30 inside of pedestal, for connecting with pcb board 20, the other end of leading foot 40
It is set to 30 outside of pedestal.In the present embodiment, leading foot 40 uses the filling-in bit terminal of ISO requirement.Pcb board 20 and leading foot 40 connect
It is assembled to after connecing in the shell 10 of a certain amount of encapsulating heat-conducting glue of encapsulating, encapsulating heat-conducting glue becomes by baking-curing to be had excellent performance
Thermosetting polymer insulating materials.In order to during baking-curing encapsulating heat-conducting glue be smoothly discharged, internal gas,
Guarantee technological quality, in the utility model, gas vent 31 is offered on pedestal 30, for encapsulating heat-conducting glue in baking process
The heated discharge of internal gas, after baking, seal vents 31 obtain finished product.
In the present embodiment, pedestal 30 is fixed on shell 10 by encapsulating encapsulating heat-conducting glue, and shell 10 is made of metal material,
The thermal coefficient of encapsulating heat-conducting glue is greater than or equal to 1, and the heat generated on pcb board 20 is transmitted to metal by encapsulating heat-conducting glue
Shell 10 on, and then pass in external environment, can be improved the heat resistance of relay.
Since error-proof structure is arranged on pcb board 20, certain space will be occupied, that is, reduces the sky for arranging component
Between, increase design difficulty, the utility model is converted from pcb board 20 to pedestal on the basis of pedestal 30 are arranged, by error-proof structure
On 30, that is, the side wall of pedestal 30 is provided with fool proof notch 34, the inner wall of shell 10 corresponds to fool proof notch 34 and is provided with fool proof muscle
Item 11 realizes the fool proof installation of pedestal 30 by the cooperation of fool proof notch 34 and fool proof rib 11.Due to leading foot 40 and pedestal
30 are structure as a whole, and pcb board 20 is fixedly welded with leading foot 40, and in turn, the fool proof installation of pedestal 30 is the fool proof of pcb board 20
Installation is realized while guaranteeing to install convenience, increases the usable floor area of pcb board 20.
It, then can be in pedestal 30 in order to more easily recognize the position of fool proof notch 34, and then convenient for differentiating installation direction
Side wall correspond to fool proof notch on the position of fool proof notch is corresponded to along the surface of position or pedestal 30, offer mark notch
35, the quantity of mark notch 35 matches with position and fool proof notch 34.In turn, in assembling process, can more easily divide
The position for distinguishing fool proof notch 34 avoids overturning pedestal 30 that from capable of just finding fool proof notch 34 in which side.Also, pass through difference
The mark notch 35 of quantity can intuitively judge the assembly direction of pedestal 30.In the present embodiment, mark notch 35 is arranged the bottom of at
The top surface seamed edge of seat 30 can be considered that mark notch 35 through the side wall of pedestal 30 and the crossover position on surface, visually more holds
Easily discovery, and it is not take up the space on too many side and surface.
Preferably, in order to realize more preferably fool proof effect, 30 2 face of pedestal or more than side wall be arranged fool proof notch 34,
34 quantity of fool proof notch of each surface side wall is different.In the present embodiment, a fool proof is respectively set in opposite both sidewalls
34, two fool proof notches 34 of notch.
For the guarantee leakproofness of pedestal 30, prevents from forming gap between fool proof notch 34 and pedestal 30, cause ponding, powder
The sundries such as dirt enter and corrode encapsulating heat-conducting glue, and then influence leakproofness and complete appearance and beauty, and fool proof notch 34 does not pass through
Wear pedestal 30, and then lift-off seal.
Compared with prior art, the utility model is not due to using the direct encapsulating of encapsulating heat-conducting glue, thus, in order to realize bottom
Seat 30 is flushed with shell 10, and in the present embodiment, the inner wall of shell 10 is provided with limit ribs 12, by limit ribs 12 to pedestal
30 form contact limit, and the height of limit ribs 12 is lower than fool proof rib 11.The height of limit ribs 12 determines pcb board 20 in shell
Mounting height in body 10, when it is implemented, the height of limit ribs 12 and the thickness of pedestal 30 can be arranged according to demand is implemented
Degree controls mounting height of the pedestal 30 in shell 10, as the surface of pedestal 30 is flushed with shell 10.
Another effect of pedestal 30 is to facilitate setting foot bit identification, and the surface of pedestal 30, which corresponds to leading foot 40 and is provided with, determines
Justice mark 33.Wherein, definition mark 33 is to pass through the mark of Mo Ke or laser marking formation concaveconvex structure.
In the present embodiment, as shown in figure 4, the frustum penetrated through centered on gas vent 31, gas vent 31 is sealed by rivet hot；If
The position for setting frustum forms sink deck 32, and frustum is set to sink deck 32, and the apical side height of frustum is not higher than pedestal 30
Surface.The structure of the gas vent 31 is convenient for scalding riveting sealing, avoids because of 31 unsealing of gas vent, the accumulation of the external impurities such as steam
And corrode encapsulating heat-conducting glue, and then influence leakproofness.
Above-described embodiment is intended merely to illustrate the utility model, and is not used as the restriction to the utility model.As long as
According to the technical essence of the utility model, above-described embodiment is changed, modification etc. will all fall in the right of the utility model
In the range of it is required that.
