Embodiment Construction

[0015] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, the present invention designs a fixed mounting PCB board, including a PCB body 1 and a fixed through hole 2 arranged on the PCB body 1, the number of the fixed through hole 2 is at least one, and the PCB body 1 includes a circuit conductive layer; It also includes locking ferrules 3 respectively arranged in each fixing through hole 2, the locking ferrules 3 are not in contact with the circuit conductive layer in the PCB body 1, the number of locking ferrules 3 is consistent with the number of fixing through holes 2, and the locking ferrules The sleeve 3 includes a cylindrical sleeve 4 with openings at both ends, and protruding edges 5 respectively arranged on the opening edges at both ends of the cylindrical sleeve 4. The protruding edges 5 are on the plane where the edge of the opening is ...

Abstract

The invention relates to a fixedly installed PCB. The PCB comprises a PCB body (1), fixing through holes (2) formed in the PCB body (1), and locking clamping sleeves (3) arranged in the fixing through holes (2) respectively. The PCB body (1) comprises a circuit conducting layer. The locking clamping sleeves (3) do not make contact with the circuit conducting layer of the PCB body (1). The number of the locking clamping sleeves (3) is consistent with the number of the fixing through holes (2). Each locking clamping sleeve (3) comprises a cylindrical sleeve (4) with the two ends open, and protruding edges (5) arranged on the edges of the openings in the two ends of the cylindrical sleeve (4) respectively, the protruding edges (5) on the plane where the opening edges are located extend in the direction far away from the center of the openings along the opening edges, and the external diameter of each cylindrical sleeve (4) is matched with the internal diameter of the corresponding fixing through hole (2). The structural improvement is made on an existing PCB, the PCB can be effectively prevented from being extruded in the installing process, and the service life of the PCB is guaranteed.

Description

technical field [0001] The invention relates to a PCB board for fixed installation. Background technique [0002] PCB board is printed circuit board, also known as printed circuit board, printed circuit board, circuit board for short, with insulating board as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component Holes, fastening holes, metallized holes, etc.), used to replace the chassis of electronic components installed in the past, and realize the interconnection between electronic components. Because this kind of board is made by electronic printing, it is called "printed" circuit board; according to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. They are ...
