Technical Field

The invention relates to the technical field of circuit boards, in particular to a circuit board capable of preventing carbon oil from leaking oil and being short-circuited.

Background

The carbon oil is printed on the appointed position of the PCB, and a qualified carbon film with a certain resistance value is formed to replace the original resistance element after the curing test of the oven is OK. The manufacturing is similar to character silk-screen printing, the difference is that only carbon oil has good conductive performance, the characters are made of semiconductor materials and only play roles of marking and isolated welding, and because the carbon oil has good conductive performance, when the carbon oil is coated on a circuit board, the carbon oil flows due to the deviation of the circuit board, so that the circuit board is short-circuited.

Disclosure of Invention

The invention aims to solve the defect that a circuit board is short-circuited due to the fact that carbon oil flows in the prior art, and provides the circuit board capable of preventing carbon oil from being short-circuited due to oil seepage.

In order to achieve the purpose, the invention adopts the following technical scheme:

a circuit board for preventing carbon oil from being leaked and short-circuited is designed, and comprises a circuit board, wherein a connecting rod is connected to the circuit board through a fixing mechanism, a sliding sleeve is sleeved on the connecting rod, an intercepting frame is fixedly connected to the sliding sleeve, and a fastening mechanism is arranged on the intercepting frame;

the fixing mechanism comprises two through grooves, two fastening nuts, two connecting sleeves, two fixing columns and two connecting blocks, the two through grooves are parallelly arranged on the circuit board, the two connecting sleeves are fixedly connected with two ends of the connecting rod, the two fixing columns are respectively inserted into the through grooves, one ends of the two fixing columns are fixedly connected with the connecting blocks, the two connecting sleeves are respectively sleeved on the fixing columns, and the two fastening nuts are respectively in threaded connection with the fixing columns.

Preferably, the fastening mechanism comprises an L-shaped connecting block and a fastening bolt, the L-shaped connecting block is fixedly connected with the sliding sleeve, and the fastening bolt penetrates through the L-shaped connecting block in a threaded manner.

Preferably, the fastening bolt and the opposite inner sides of the connecting rod are fixedly connected with abutting blocks.

Preferably, the sliding sleeve is vertically and fixedly connected with an upright post.
