Embodiment
[0031] see Figure 1 to Figure 4 As shown, a kind of DC relay with sampling signal pin of the present invention comprises two static spring lead-outs 11,12 and housing 2; Two static spring lead-outs 11,12 are respectively fixed on the housing 2, two The upper parts of the lead-out ends 11 and 12 of the static springs are respectively exposed outside the housing to be connected with the corresponding external circuit, and the lower parts of the lead-out ends 11 and 12 of the two static springs are respectively accommodated in the housing to be used for connecting with the dynamic of the relay. The spring assembly is matched, that is, the lower parts of the two static spring lead-out ends 11, 12 respectively pass through the shell wall of the shell and enter the shell; the DC relay also includes a sampling signal pin 3, and one end 31 of the sampling signal pin 3 is used as a signal connection The input end is connected to one of the static spring lead-out ends 12 of the two sta...

The invention discloses a DC relay with a sampling signal pin. The DC relay comprises two static spring leading-out terminals, a shell and the sampling signal pin, wherein the two static spring leading-out terminals are fixed on the shell separately; the upper parts of the two static spring leading-out terminals are exposed out of the shell separately and are used for being connected with corresponding external circuits; the lower parts of the two static spring leading-out terminals are accommodated into the shell separately and are used for being matched with a dynamic spring assembly of therelay; and one end of the sampling signal pin is connected with one static spring leading-out terminal of the two static spring leading-out terminals as a signal leading-in terminal and the other endof the sampling signal pin is fixed on the shell as a signal leading-out terminal. The DC relay has the characteristics of being simple in structure, easy to operate and high in connection reliability.
Description
technical field [0001] The invention relates to the technical field of relays, in particular to a DC relay with a sampling signal pin. Background technique [0002] The relay is an electronic control device, which has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), usually used in automatic control circuits, it actually uses a smaller current to control a larger An "automatic switch" of electric current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] The DC relay is one of the relays. An existing DC relay includes two static spring leads, a housing and a moving spring assembly. The two static spring leads are respectively fixed on the shell, and the static spring The upper part of the lead-out end is exposed outside the shell, and is used to connect with external electronic components, such as connecting loads, etc. The lower part of the ...
