Abstract
The utility model discloses a new solid relay, which comprises a case, a part of circuit and an insulating solid material. The case is made up of an external cover and a base, wherein, the fixing cover of external cover is arranged on the base to form closed chamber and the circuit is arranged in this closed chamber. The remaining space of this chamber is filled with insulating solid materials to fix the circuit in the closed chamber. A plurality of conductive inserts are fixed and inserted on the base. One end of the conductive insert protrudes outwards the base and the other end of the conductive insert protrudes into the closed chamber and is connected with corresponding control wire of the circuit. During usage, the utility model matches with corresponding seat with a plurality of holes sold in the market and operations of pulling out and plugging are performed individually for each solid relay. The utility model has advantages of easy replacement, moisture-proof, dust-proof and anti-vibration.
Description
Technical field
The utility model relates to a kind of electrical apparatus control equipment, specifically is a kind of novel solid-state relay.
Background technology
Commercially available mechanical contact-type relay though change easily, is not suitable for high-frequency action at present, and the big more spark of operating current is big more.Because the mechanical contact-type relay exists such shortcoming, people have invented solid-state relay, solid-state relay comprises shell, circuit part and insulation solidfied material, by the insulation solidfied material circuit part is packaged in the shell, and the control line of circuit part is drawn outside the shell.Solid-state relay is a kind of contactless switch element of all being made up of the solid-state electronic element, it utilizes electricity, magnetic and the light characteristic of electronic devices and components to finish input and the reliable isolation of exporting, utilize large power triode, power field effect pipe, the switching characteristic of device such as one-way SCR and bidirectional triode thyristor, reach contactless, switch on and off to no-spark controlled circuit.Solid-state relay is compared with electromechanical relay, because solid-state relay does not have component of machine, finish the contact function by solid state device, owing to there are not the parts of motion, therefore can be in HI high impact, the work down of the environment of vibration is owing to form the inherent characteristic of the components and parts of solid-state relay, determined that the life-span of solid-state relay is long, the reliability height.At present commercially available solid-state relay is many need to be fixed on the appliance plate in addition with single installation, though performance is better, the corresponding connecting line of need dismantling when changing is changed trouble.Also have the multichannel of doing with the circuit board form integrated, a path loss is bad will be pulled down the monoblock circuit board and could change if the integrated solid-state relay of this multichannel has, and protection against the tide, prevent dust, the vibrationproof performance is also poor.
The utility model content
The purpose of this utility model provides a kind of suitable high-frequency high-power, changes and novel solid-state relay moistureproof, dustproof, the vibrationproof better performances easily.
The technical solution of the utility model is such: a kind of novel solid-state relay, comprise shell, circuit part and insulation solidfied material, above-mentioned shell comprises outer cover and base, above-mentioned outer cover fixed cover is located at and is formed airtight cavity volume on the above-mentioned base, foregoing circuit partly places in this airtight cavity volume, the residual cavity of above-mentioned airtight cavity volume is filled by above-mentioned insulation solidfied material, with the foregoing circuit partial fixing in above-mentioned airtight cavity volume; Be fixedly plugged with the plural conductive inserted sheet on the above-mentioned base, this conduction inserted sheet one end extends outside the base, and the other end stretches in the above-mentioned airtight cavity volume and is electrically connected with the corresponding control line of foregoing circuit part.
Foregoing circuit partly is a chip, is integrated with circuit board, large power, electrically sub-element and peripheral cell on this chip.
The bottom of above-mentioned outer cover is provided with hole clipping, and above-mentioned base and the corresponding position of above-mentioned hole clipping are provided with the elasticity fastener.
After adopting such scheme, novel solid-state relay of the present utility model, the commercially available corresponding porous seat of adapted during work, the respective aperture that only needs the conduction inserted sheet on the base to be inserted the porous seat is promptly finished installation, the respective aperture that the inserted sheet that will conduct electricity during replacing is extracted the porous seat gets final product, change very conveniently, and each solid-state relay carries out plug moistureproof, dustproof, vibrationproof better performances respectively separately when changing.The utility model is compared with the mechanical contact-type relay, has the advantage of suitable high-frequency high-power, compares with existing solid-state relay, has to change advantage convenient, moistureproof, dustproof, the vibrationproof better performances.
Description of drawings
Fig. 1 is the structural representation of outer cover of the present utility model and base.
Fig. 2 is a front of the present utility model cut-away view.
Fig. 3 is a side of the present utility model cut-away view.
Embodiment
A kind of novel solid-state relay of the utility model as shown in Figure 1, 2, 3, comprises outer cover 1, chip 2, base 3, conduction inserted sheet 4 and insulation solidfied material 5, is integrated with circuit board, large power, electrically sub-element and peripheral cell on the chip 2.
As shown in Figure 1, outer cover 1 is square transparent shell, and a side offers opening 11, the pair of sidewalls of outer cover 1 offers a pair of hole clipping 12 near the position of opening 11, base 3 comprises mouth-sealed portion 31 that exposes outside the opening 11 and the connecting portion 32 that is embedded in the opening 11, connecting portion 32 is provided with a pair of elasticity fastener 321 with hole clipping 12 corresponding positions, when connecting portion 32 inserts in the opening 11, elasticity fastener 321 is stuck in the corresponding hole clipping 12 through flicking after being out of shape, outer cover 1 is fixed on the base 3, forms a sealed volume.
Shown in Fig. 2,3, chip 2 places in the sealed volume that outer cover 1 and base 3 be sealed to form, and the residual cavity of this airtight cavity volume is filled by insulation solidfied material 5, by insulation solidfied material 5 chip 2 is fixed in this airtight cavity volume.Be fixedly plugged with plural conductive inserted sheet 4 on the base 3, outside the conduction inserted sheet 4 one end protuberate basic units 3, the other end stretches into interior the welding with the corresponding control line of chip 2 of above-mentioned airtight cavity volume and realizes being electrically connected.
