Abstract
The utility model provides an electronic control unit of an instant electric water heater. The electronic control unit of the instant electric water heater comprises a circular board, four 10-ampere relays and wiring terminal platforms. The 10-ampere relays are arranged on the circuit board in an array mode. Each wiring terminal platform is arranged on the circuit board and located on the front side of the corresponding relay. Each relay is connected with the corresponding wiring terminal platform through a lead. Each wiring terminal platform comprises an insulation body, wherein five grooves are downwards formed from the upper surface of the insulation body in a concave mode, the bottom face of each groove is provided with a metal sheet in an embedded mode, a screw hole penetrates through each metal sheet, and a screw is installed in each screw hole. As the relays are in the specification of 10 amperes, the size of the relays is largely decreased; the relays are connected with the wiring terminal platforms through the leads in a guide mode, then the wiring terminal platforms are connected with external wires due to cooperation of the screws and the screw holes, so that product reliability is largely improved, the wires are prevented from falling off from the wiring terminal platforms, and the length of each wire decreases.
Description
Technical field
The utility model relates to a kind of instant electric water heater's electronic-controlled installation.
Background technology
A kind of instant electric water heater's electronic-controlled installation in the market, it comprises a circuit board, one relay is set on described circuit board, described relay is all the specification that adopts 30 amperes or 16 amperes, come the Current Control on described circuit board, and the output of relay is connected directly to heat-generating pipe by lead-in wire, when said apparatus work, because the relay volume of 30 amperes or 16 amperes specifications is larger, the area that causes taking circuit board is excessive, and lead-in wire is directly connected on heat-generating pipe by the output of relay, cause going between long, be easy to cause come off between lead-in wire and the output of relay, affect the quality of product.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and a kind of instant electric water heater's electronic-controlled installation is provided, and it has little, the practical characteristic of volume.
The utility model is achieved in that a kind of instant electric water heater's electronic-controlled installation, and it comprises:
One circuit board;
The relay of four 10 peaces is arranged in matrix on described circuit board;
One coupling terminal block, be arranged on described circuit board and be positioned at the front side of relay, between described relay and described coupling terminal block, connect by lead-in wire, described coupling terminal block comprises an insulating body, be arranged with five grooves downwards from the upper surface of described insulating body, described in each, the bottom surface of groove is embedded a sheet metal, provides a screw in described sheet metal, installs a screw in described screw.
Further, a jube is set described in adjacent two between groove.
Further, described groove extends forward and runs through the front end face of described insulating body.
Further, before and after described relay is on described circuit board, two rows arrange, and the quantity of each row's relay is two.
Further, wherein two described relays are arranged in parallel by lead-in wire.
Further, between described relay and corresponding described sheet metal, connect by lead-in wire.
Further, described insulating body is strip.
The utility model provides a kind of instant electric water heater's electronic-controlled installation, and it comprises: a circuit board; The relay of four 10 peaces is arranged in matrix on described circuit board; One coupling terminal block, be arranged on described circuit board and be positioned at the front side of relay, between described relay and described coupling terminal block, connect by lead-in wire, described coupling terminal block comprises an insulating body, be arranged with five grooves downwards from the upper surface of described insulating body, described in each, the bottom surface of groove is embedded a sheet metal, provides a screw in described sheet metal, installs a screw in described screw.Because described relay adopts 10 specifications of pacifying, the volume of described relay is reduced greatly, and connect by lead-in wire between described relay and described coupling terminal block, described coupling terminal block is connected with extraneous wire with the cooperation of screw by screw again, greatly improve the stability of product, prevent that wire from coming off from coupling terminal block, also saved the length of wire.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Instant electric water heater's electronic-controlled installation stereogram that Fig. 1 provides for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1 and Fig. 2, the utility model embodiment provides a kind of instant electric water heater's electronic-controlled installation, and it comprises: relay 2, coupling terminal blocks 3 of a circuit board 1, four 10 peaces.
