Abstract
The utility model relates to a kind of non-arc contactor silicon controlled module structure, for solving the miniaturization of silicon controlled module in hybrid non-arc contactor product and being convenient to install, is made up of metal connecting sheet, controlled silicon chip, triggering lead-in wire, encapsulating material.Entirety is strip structure in the form of sheets, metal connecting sheet is drawn respectively in left and right two ends, inside being provided with 2 pieces of controlled silicon chips is arranged side by side at grade, 2 strip metal braces are welded on upper surface and the lower surface of 2 pieces of controlled silicon chips respectively, burn-on again and trigger lead-in wire, the encapsulating material encapsulation of chip area insulation, or wrap up with the housing that encapsulating material is made.The utility model, for the structure of non-arc contactor and performance characteristics, has carried out simplified design to silicon controlled module, without heat abstractor, has significantly reduced volume, and with low cost, is conducive to miniaturization and the batch production of hybrid non-arc contactor.
Description
Technical field
The utility model belongs to low voltage component, is specifically related to a kind of non-arc contactor silicon controlled module structure.
Background technology
In the hybrid non-arc contactor product that mechanical contact and thyristor form, if use general silicon controlled module, no matter be the product that specialized vendor provides, because planform reason is not easy to install, volume is too large, the overall volume of contactor product is increased too many, be all difficult to obtain practical application.
The operation principle of hybrid non-arc contactor: when major loop is connected, first allow controlled silicon conducting, then allow mechanical contact close, then controllable silicon turns off; When major loop disconnects, first allow controlled silicon conducting, then allow mechanical contact disconnect, then controllable silicon shutoff.In these two processes, be all that mechanical contact performs closed or disconnection action, therefore can not produce electric arc when controllable silicon first conducting; And the time of each conducting of controllable silicon is very short, it is approximately Millisecond, when contactor works, load current is born primarily of mechanical contact, controllable silicon is brief energization, can not produce very large heat, without the need to installing heat abstractor additional, and current specification can be less than one or two grade of contactor rated current.According to these features, a kind of silicon controlled module of special construction need be designed, realize miniaturized and be convenient to install, making it be applied to completely in hybrid non-arc contactor product, and the batch production of hybrid non-arc contactor is become a reality.
Summary of the invention
For solving the miniaturization of silicon controlled module and being convenient to install, make it in hybrid non-arc contactor product, obtain practical application, the utility model provides the non-arc contactor silicon controlled module structure that a kind of structure is simple, volume is little, cost is low, easy for installation.
Technical scheme
The utility model non-arc contactor silicon controlled module structure, be made up of metal connecting sheet, controlled silicon chip, triggering lead-in wire, encapsulating material, entirety is strip structure in the form of sheets, inside being provided with two pieces of controlled silicon chips is arranged side by side at grade, be provided with two strip metal braces to draw from left and right two ends respectively, wherein a strip metal brace is welded on the upper surface of described two pieces of controlled silicon chips, draw from left end, another strip metal brace is welded on the lower surface of described two pieces of controlled silicon chips, draws from right-hand member.The trigger region of described two pieces of controlled silicon chips is respectively welded with one and triggers lead-in wire, and totally two triggering lead-in wires are drawn from any one end metal connecting sheet.The encapsulating material encapsulation of chip area insulation, or wrap up with the housing that encapsulating material is made.During due to hybrid non-arc contactor work, all when the first conducting of silicon controlled module, mechanical contact performs closed or disconnection action, silicon controlled module is brief energization, very large heat can not be produced, therefore without the need to installing heat abstractor additional, and current specification can be less than one or two grade of contactor rated current.
In technique scheme, this non-arc contactor silicon controlled module entirety, in in-line sheet, is installed on non-arc contactor; Also, after double-end metal connecting sheet can being bent, be installed on non-arc contactor.Fixing for convenience of installing, metal connecting sheet is provided with the hole for installing.
Beneficial effect
The utility model is for the structure of non-arc contactor and performance characteristics, simplified design has been carried out to silicon controlled module, structure is simple, one-piece sheet, strip structure are convenient to install, without heat abstractor, significantly reduce volume, and with low cost, be conducive to miniaturization and the batch production of hybrid non-arc contactor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is the utility model structure cutaway view.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is made up of metal connecting sheet, controlled silicon chip, triggering lead-in wire, encapsulating material, entirety is strip structure in the form of sheets, inside being provided with two pieces of controlled silicon chips 3,4 is arranged side by side at grade, be provided with two strip metal braces 1,7 to draw from left and right two ends respectively, wherein a strip metal brace 1 is welded on the upper surface of described two pieces of controlled silicon chips 3,4, draw from left end, another strip metal brace 7 is welded on the lower surface of described two pieces of controlled silicon chips 3,4, draws from right-hand member.The trigger region of described 2 pieces of controlled silicon chips 3,4 is respectively welded with one and triggers lead-in wire, and totally two triggering lead-in wires (namely trigger lead-in wire 5 and trigger lead-in wire 6) are drawn from any one end metal connecting sheet.The encapsulating material encapsulation of chip area insulation, or wrap up with the housing that encapsulating material is made.
In the above-described embodiment, this non-arc contactor silicon controlled module entirety, in in-line sheet, is installed on non-arc contactor; Also, after double-end metal connecting sheet 1,7 can being bent, be installed on non-arc contactor.Fixing for convenience of installing, metal connecting sheet 1,7 is provided with the hole for installing.
