Abstract
The utility model discloses the boring base plate of a kind of PCB, be made up of left fishplate bar and right fishplate bar, described left fishplate bar is identical with the structure of right fishplate bar, and its both sides are provided with joint, and the joint on described left fishplate bar and right fishplate bar can cooperatively interact; Described joint is notch cuttype; The sidewall of described joint is provided with magnetosphere.The boring base arrangement of this PCB is simple, is spliced and can be changed position at any time according to surface condition, improve the utilization ratio of base plate, saved material, reduced production cost by two boards.
Description
technical field:
The utility model relates to PCB manufacture field, particularly relates to the boring base plate of a kind of PCB.
background technology:
Printed circuit board, also known as printed circuit board (PCB), printed substrate, be called for short printed board, English abbreviation PCB or PWB, is base material with insulation board, is cut into certain size, at least with a conductive pattern on it, and cloth porose (as component hole, fastener hole, plated-through hole etc.), be used for replacing the chassis of device electronic devices and components in the past, and realize being interconnected between electronic devices and components.
In order to conveniently corresponding hole can be offered on PCB, pcb board is generally all provided with special boring grab, and in order to prevent PCB when holing through fixture, crumble drill bit, the below of PCB is all provided with base plate, but uneven due to the position in hole on PCB, the boring ratio that therefore some local drill bit causes after base plate uses a period of time is closeer, some place is rarer, but because this base plate is integral type, therefore changing once needs must integral replacing, compares waste.
summary of the invention:
Technical problem to be solved by this invention is, provides the boring base plate of a kind of PCB that can increase operation rate.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: the boring base plate of a kind of PCB, be made up of left fishplate bar and right fishplate bar, described left fishplate bar is identical with the structure of right fishplate bar, its both sides are provided with joint, and the joint on described left fishplate bar and right fishplate bar can cooperatively interact.
As preferably, described joint is notch cuttype.
As preferably, the sidewall of described joint is provided with magnetosphere.
Compared with prior art, usefulness of the present invention is: the boring base arrangement of this PCB is simple, is spliced and can be changed position at any time according to surface condition, improve the utilization ratio of base plate by two boards, save material, reduce production cost.
accompanying drawing illustrates:
Accompanying drawing 1 is the boring base plate vertical view of a kind of PCB of the present invention;
Fig. 2 is a kind of PCB of the present invention boring base plate end face structure schematic diagram;
Fig. 3 is the partial enlarged drawing of A in Fig. 2.
In figure: 1, left fishplate bar; 2, right fishplate bar; 3, joint; 4, magnetosphere.
embodiment:
Describe the present invention below in conjunction with the drawings and specific embodiments.
The boring base plate of a kind of PCB shown in Fig. 1 and Fig. 2, be made up of left fishplate bar 1 and right fishplate bar 2, described left fishplate bar 1 is identical with the structure of right fishplate bar 2, its both sides are provided with joint 3, and the joint on described left fishplate bar 1 and right fishplate bar 2 can cooperatively interact, the conveniently docking of diverse location, described joint 3 is in notch cuttype; Conveniently left fishplate bar 1 and right fishplate bar 2 are not easy skew after being connected, and the sidewall of described joint 3 is provided with magnetosphere 4.
Its concrete occupation mode is as follows, left fishplate bar 1 and right fishplate bar 2 are aimed at good position, then the joint 3 of two boards is docking together, mutually inhaled together by the magnetosphere 4 on joint 3 between left fishplate bar 1 and right fishplate bar 2, when the face on wherein one block of plate cannot continue to use, this plate is carried out turn-over, and then is docking together, carry out replacing docking with this, ensure can be fully used in all faces on left fishplate bar 1 and right fishplate bar 2.
The boring base arrangement of this PCB is simple, is spliced and can be changed position at any time according to surface condition, improve the utilization ratio of base plate, saved material, reduced production cost by two boards.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
