Description

The electromagnetic switch contact system
Technical field
The present invention relates to a kind of electromagnetic switch, particularly a kind of electromagnetic switch contact system.
Background technology:Traditional electromagnetic switch contact system, movable contact spring and static contact spring piece directly are welded on the drain pan output pin, and transmission mechanism promotes movable contact spring and contacts realization load handoff functionality with static contact spring piece.
Traditional electromagnetic switch contact system, simple in structure, assembling easily.Weak point is: contact system is with after transmission mechanism is connected; Two reeds are in the space of complete closed; This makes the adjustment of reed be in the situation of blind accent, and adjustment reed parameter is difficulty and can't directly measure the two reeds pressure in when contact very, when causing transmission mechanism to promote movable contact spring to contact with static contact spring piece; Or actuating length occurs and cross ambassador's reed and lose to play phenomenon, or the actuating length deficiency occurs and make the unreliable phenomenon of contact.Reed directly links to each other with the drain pan output pin in addition, occurs easily causing the reed change in location to occur losing efficacy because of pin receives external mechanical force effect displacement.
Summary of the invention: to the problem of above-mentioned contact system existence; The present invention proposes and a kind of the contact system riveting is installed to the structure on the circuit module; Solved blind accent structure; Reed pressure can directly be measured, changed the connected mode that reed directly links to each other with outside output pin simultaneously, avoided reed to receive the possibility that outside harmful effect was lost efficacy.In addition, framework circuit on circuit module is realized load protection and input signal controlled function.
Formation of the present invention: form by printed circuit board, movable contact spring, static contact spring piece, reset reed, electronic devices and components; On printed circuit board, adorn movable contact spring and static contact spring piece with the rivet riveting; Reset reed superposes on the movable contact spring; Welding electronic component on the printed circuit board, circuit module are divided into load protection circuit part and input control circuit part;
The method that the present invention solves blind accent is: the movable contact spring and the static contact spring piece riveting of contact system are installed on the printed circuit board, again drain pan output pin and printed circuit board are realized being electrically connected, on movable contact spring, increased reset reed; All there is pad at the rivet hole place of reed, and reed contact is got in the circuit, after the transmission mechanism of electromagnetic switch and printed circuit board assemble and be connected; Reed is in open environment; Can adjust reed this moment according to needs, afterwards again with the drain pan assembling, and the sealing printed circuit board;
The present invention solves reed contact and avoids outside dysgenic measure and be: reed contact is separated with pin, and the reed contact riveting installs on the printed circuit board, pin is linked to each other with printed circuit board again, uses printed circuit board to transfer;
The present invention realizes that the measure of load protection and input signal controlled function is: the printed circuit board circuit contains two parts, and one is contact or load protection circuit part, and one is the input control circuit part; Load protection circuit partly contains reed, contact and respective electronic components and parts; And in this circuit, designing contact arc-suppression circuit or other protective circuits as required, the input control circuit part realizes reverse polarity protection or time delayed signal control to input voltage or current signal.
Compare with prior art; Positive role of the present invention is: a kind of reed contact system of integrating the circuit module function is provided; This structure can be on the function basis of realizing traditional reed contact switch load; Solved the hidden danger that reed contact was lost efficacy by outside harmful effect, the feature richness of realizing simultaneously load protection and input signal are controlled product function.Simple in structure, reliability is high, failure rate is low, and assembling is simple, space availability ratio is high.
Description of drawings: accompanying drawing is a structural representation of the present invention.
Among the figure: 1 load protection circuit part, 2 rivets, 3 movable contact springs, 4 static contact spring pieces, 5 printed circuit boards, 6 input control circuit parts, 7 reset reeds, 8 transmission mechanisms, 9 drain pan output pins.
Embodiment: as shown in the figure; A kind of electromagnetic switch contact system; Be made up of printed circuit board, movable contact spring, static contact spring piece, reset reed, electronic devices and components, it is characterized in that: with rivet 2 rivetings dress movable contact spring 3 and static contact spring piece 4, reset reed 7 superposes on the movable contact spring on printed circuit board 5; Welding electronic component on the printed circuit board 5, circuit module are divided into load protection circuit part 1 and input control circuit part 6;
The method that the present invention solves blind accent is: the movable contact spring 3 and static contact spring piece 4 rivetings of contact system are installed on the printed circuit board 5; Again drain pan output pin 9 and printed circuit board are realized being electrically connected, on movable contact spring, increased reset reed 7, all there is pad at the rivet hole place of reed; Reed contact is got in the circuit; After the assembling of the transmission mechanism 8 of electromagnetic switch and printed circuit board was connected, reed was in open environment, can adjust reed according to needs at this moment; Again with the drain pan assembling, seal printed circuit board afterwards;
The present invention solves reed contact and avoids outside dysgenic measure and be: reed contact is separated with pin, and the reed contact riveting installs on the printed circuit board, pin is linked to each other with printed circuit board again, uses printed circuit board to transfer;
The present invention realizes that the measure of load protection and input signal controlled function is: the printed circuit board circuit contains two parts, and one is contact or load protection circuit part, and one is the input control circuit part; Load protection circuit partly contains reed, contact and respective electronic components and parts; And in this circuit, designing contact arc-suppression circuit or other protective circuits as required, the input control circuit part realizes reverse polarity protection or time delayed signal control to input voltage or current signal.
