Background technology
Solid-state relay (Solid State Relay, abbreviation SSR) is by microelectronic circuit, discrete electronic device, and the noncontacting switch that power electronic power device is formed has been realized the isolation of control end and load end with isolating device.The input of solid-state relay reaches direct driving large current load with small control signal.In order to make solid-state relay can have the function that shows break-make, also introduce LED light, and represent the on-off switch state through the light on and off of LED light at solid-state relay.
The implementation that the solid-state relay of existing tape light adopts is: (1), offer an aperture at shell, the LED light of plug-in unit is exposed from this aperture, judge through the on and off of observing the LED light in the aperture and open/off state.(2), adopt the LED light of paster and a leaded light post be installed, through the leaded light post, the photoconduction of sending out the LED light of pasting goes out shell, judges through the light situation of going out of observation leaded light post and opens/off state.These 2 kinds of implementations all need be offered through hole on the shell of solid-state relay, the second way more need increase by a leaded light post.Main, these two kinds of methods generally can only be used for the bigger solid-state relay of volume ratio.
Yet for the less solid-state relay of volume ratio, the solid-state relay that causes small size because of its design feature is the function of tape light not.The general structure of small size solid-state relay is: electronic devices and components are welded on printed board and constitute the relay circuit plate; This relay circuit plate places in the shell; And the extraction electrode pin, relay circuit plate in the shell and the space filling epoxy resin between the shell are fixed.The small size solid-state relay is difficult for realizing that the reason of LED light function is following: the less solid-state relay of volume ratio all is to be welded on relevant electronic devices and components in the printed board; Pack printed circuit board in the cuboid shell that has only an opening into then, fill with the epoxy resin of black.If LED light is built-in, then can be blocked by the epoxy resin of black, can't printing opacity; If expose, then need perforate on shell, cause leaking glue easily, increase the production difficulty of product.
Therefore, in some occasion of using the small size solid-state relay, the client need use LED light to know the break-make operating state of solid-state relay, just needs the client on control board, oneself to add LED light.
The utility model content
What in view of this, the utility model proposed that a kind of technical scheme solves the small size solid-state relay can't be with the LED light problem.Thereby make the small size solid-state relay directly tape light and need not to add indicator light with the on off state of indication product.
The following technical scheme of the concrete employing of the utility model:
The solid-state relay of tape light; Its structure is: electronic devices and components and LED light are welded on printed board and constitute the relay circuit plate, and this relay circuit plate places in the shell, and the extraction electrode pin; This LED light is positioned at closes on the outer casing top surface position; The periphery of the LED light on the relay circuit plate is coated with printing opacity glue, and printing opacity glue extends to shell, has part to contact with shell; Filling epoxy resin in the remaining space in the shell is fixed, this shell is printing opacity or semi-transparent casing again.
Further, described LED light is a LED sideward emitting.The employing LED sideward emitting can be at the visible indicator light light prompt of the end face of solid-state relay shell.
Further, described printing opacity glue is to be bulk to be coated on outside the LED light on the appliance circuit plate.Printing opacity glue is to be bulk to coat LED light, can solve LED light with minimum printing opacity glue material and covered the problem of blocking by the epoxy resin of black.
Further, described printing opacity glue is to be strip to be coated on outside the LED light on the appliance circuit plate.Printing opacity glue is to be strip to coat LED light, can solve LED light and covered the problem of blocking by the epoxy resin of black, and easy to process.
The utility model adopts technical scheme as above, and the shell that can not be used in solid-state relay is offered through hole, can not cause leaking the problem of glue; Use printing opacity or semi-transparent casing to cooperate LED sideward emitting simultaneously, can on the solid-state relay of small size, directly realize the function of LED indication on off operating mode.The solid-state relay production technology of the tape light of the utility model is simple, and cost is low.

Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Embodiment 1:
This example structure is: electronic devices and components 5 are welded on printed board with LED light 1 and constitute relay circuit plate 6; This relay circuit plate 6 places in the shell 4; And extraction electrode pin 7, this LED light 1 is positioned at closes on shell 4 top side location, and this LED light 1 is LED sideward emitting or positive illuminated LED; LED sideward emitting (can see the indicator light light prompt) preferably at the end face of solid-state relay shell; The periphery of the LED light 1 on the relay circuit plate 6 is coated with printing opacity glue 2, and printing opacity glue 2 extends to shell, has part to contact with shell 4; Again that filling epoxy resin in the remaining space in the shell 43 is fixing, this shell 4 is printing opacity or semi-transparent casing.Described printing opacity glue 2 is to be bulk to be coated on outside the LED light 1 on the appliance circuit plate 6.Printing opacity glue 2 is to be bulk to coat LED light 1, can solve LED light with minimum printing opacity glue material and covered the problem of blocking by the epoxy resin 3 of black.
Embodiment 2:
This example structure is: electronic devices and components 5 are welded on printed board with LED light 1 and constitute relay circuit plate 6; This relay circuit plate 6 places in the shell 4, and extraction electrode pin 7, and this LED light 1 is positioned at closes on shell 4 top side location; Preferred LED light 1 is a LED sideward emitting; The periphery of the LED light 1 on the relay circuit plate 6 is coated with printing opacity glue 2, and printing opacity glue 2 extends to shell 4, has part to contact with shell 4; Again that filling epoxy resin in the remaining space in the shell 43 is fixing, this shell 4 is printing opacity or semi-transparent casing.Described printing opacity glue 2 is to be strip to be coated on outside the LED light 1 on the appliance circuit plate 6.Printing opacity glue 2 is to be strip to coat LED light; Can solve LED light 1 and covered the problem of blocking by the epoxy resin 3 of black, and the strip structure simple rule, it is convenient relatively to process; Consistency is high, can a little consume some printing opacity glue materials but compare embodiment 1 more.
In the foregoing description, because the shell 4 of the solid-state relay of small size is generally flat rectangular structure, the inner space is less, and the electronic devices and components that are placed on the relay circuit plate 6 in the shell 4 normally adopt SMD electronic devices and components to weld; LED light 1 also adopts adopting surface mounted LED.If adopt common positive illuminated LED to weld, then LED light can only penetrate from the side of shell 4, does not have good indicating effect.Therefore, we adopt LED sideward emitting to realize, and are welded on to be positioned at and close on the outer casing top surface position, then in relay circuit plate 6 is placed into shell 4 after, the light of LED sideward emitting can penetrate from the end face of shell 4 just.Cooperate with it simultaneously, we adopt printing opacity or semi-transparent shell 4, and LED light 1 is penetrated from shell.Simultaneously, carry out sealing and fixing because solid-state relay need pour into the epoxy resin 3 of filling black in the space in the shell 4, then LED light 1 can be capped and can't emit beam.For fear of this problem; We are coated with printing opacity glue 2 by the periphery of the LED light 1 of elder generation on relay circuit plate 6; And then remaining space filling epoxy resin 3, printing opacity glue 2 has just stoped the epoxy resin 3 of black to cover on the LED light 1, it is luminous and influence.
