Embodiment Construction
[0021] see Figure 2A and 2B , is a schematic cross-sectional view of the substrate and the elastic terminal provided in the substrate in the present invention.
[0022] As shown in the figure, the node connection coupler for circuit experiments in the present invention includes a base plate 1 and a plug assembly. The base plate 1 includes an insulating seat body 2, a plurality of slots 4 and a plurality of elastic terminals 6. Grooves 4 are formed on both sides of the insulating base 2 . In an embodiment of the present invention, the slots 4 on both sides of the insulating base body 2 are double-row slots arranged side by side, and the double-row slots include a row of inner slots 42 and a row of outer slots 41. There is a predetermined horizontal interval between the inner slot 42 and the outer slot 41 . Each elastic terminal 6 is a metal piece, which is set in the slot 4 in a one-to-one correspondence. The pin 64 at the lower end of the positioning portion 60 . see F...

The invention relates to a circuit testing node connection coupling component, comprising: a substrate comprising insulating base body, plural sockets and plural elastic terminals, where these sockets are formed on two sides of the insulating base body, these elastic terminals are arranged in the sockets, corresponding one to one; and plugging component, used to connect the elastic terminals on two sides of the insulating base body, and comprising at least two plugs and at least a lead wire to connect at least two plugs. The invention can avoiding welding, uneasy to damage components and the connected circuit by the invention is small-bulk, clearly structured and the terminals and lead wire are coated with rubber insulated layers, therefore at the time of operation, the short-circuiting can be avoided.
Description
technical field [0001] The invention relates to a plug-in board for circuit experiment, in particular to a node connection coupler for circuit experiment which facilitates the installation and connection of various discrete elements or integrated circuits. Background technique [0002] The previous node connection method is to insert the integrated circuit on the socket first, while other discrete components and wires need to be soldered or inserted on the circuit board, such as Figure 1A , 1B shown. Moreover, only one pin can be connected to each node, so it is not easy to carry out expansion connection. The circuit constituted in this way is cumbersome to change by welding and is easy to damage components, and it is not easy to carry out expansion connection, so the circuit structure cannot be reflected intuitively, and the circuit connection structure is not clear. For example, Chinese patent CN2238490Y. Contents of the invention [0003] The technical problem to be...
