Abstract

The utility model relates to an improved wire jumping structure for membrane type circuit boards. The wire jumping structure comprises a lower layer board, a clapboard and an upper layer board. A wire jumping circuit is printed at both sides of the main circuit path of the lower layer board. When the upper layer board is pasted to the clapboard, the avoidance circuit of the upper layer board is corresponding to the above of the wire jumping circuit. Then by using conductive glue or foam, the avoidance circuit is pressed with steel sheets to make the wire jumping circuit to combine with the avoidance circuit. At this time, the signal which is transmitted on the wire jumping circuit can be transmitted to another wire jumping circuit by the avoidance circuit. Therefore, the aim of transmitting signal by the wire jumping circuit can be reached.

Technical field

The utility model relates to a kind of wire jumper structure of modified model diaphragm type circuit plate, refers to that especially a kind of circuit that makes arranging on (1ayout) simplification (circuit does not have the wire jumper puzzlement) more, reduces the wire jumper structure of fraction defective and manufacturing cost.

Background technology

Known, in the circuit board line design, make designer's pain in the neck most at present, be the wire jumper part of circuit-line.When if the wire jumper layout of this circuit is not ideal enough, will causes circuit complicated more in arrangement (layout), and be difficult for design.Just as present existing glass mat when design circuit, if run into when having wire jumper partly, the designer can design this circuit respectively on different circuit boards, utilizes lead to connect again afterwards, or be multi-level with board design, to solve the wire jumper problem on the circuit board.But, if when being passed on the present existing diaphragm type circuit plate in the design of this kind circuit board, but be inapplicable, because can cause circuit board thickness thickening, and be difficult for making.

So some dealer is in order to solve this problem, then with the wire jumper contact bed hedgehopping of lower film circuit board (MEMBRANE), to solve the wire jumper problem.But when easily causing film circuit board (MEMBRANE) fold position to key in (KEY IN) in this kind design, can cause and produce the phenomenon that arches upward herein, also can cause migration (MIGRATION) situation to take place, cause the increase of printer's number of passes, and the raising of product fraction defective and cost of manufacture.

Technical scheme

Main purpose of the present utility model is to solve above-mentioned defective, avoids defective to exist, and the utility model utilizes a kind of wire jumper structure, allows circuit on circuit board simplification (circuit does not have the wire jumper puzzlement) more on layout, reduces fraction defective and manufacturing cost.

Another purpose of the present utility model, the serious problems that cause because of arching upward when being to avoid diaphragm type circuit plate (MEMBRANE) fold position to key in (KEY IN), also can avoid migration (MIGRATION) situation to take place simultaneously, and can reduce printer's number of passes and improve non-defective unit, reduce cost.

For realizing above-mentioned purpose, wire jumper structure of the present utility model includes: a lower plywood, one dividing plate and a top plate constitute, both sides, main line path at aforesaid lower plywood are printed with the wire jumper circuit, when this dividing plate fits on the lower plywood, through hole on this dividing plate is one by the wire jumper circuit and exposes state, when top plate fits on the dividing plate, avoidance circuit on this top plate is promptly on the wire jumper circuit, utilize conducting resinl again or use foam with the steel disc pressing, allow aforesaid wire jumper circuit engage with the avoidance circuit, the signal that this moment, the wire jumper circuit was transmitted can transfer on another wire jumper circuit by avoiding circuit, can reach the transmission that utilizes the wire jumper circuit to finish signal.

Relevant technology contents of the present utility model and detailed description now cooperate each description of drawings as follows.
