Description

Board splicing plate of circuit board Technical Field The embodiment of the application relates to the field of circuit boards, for example to a jointed board of a circuit board. Background The circuit board splicing plate is used for splicing a plurality of small circuit boards together so as to facilitate production. The jointed board of the circuit board can save the cost of circuit board manufacturers and improve the production efficiency. Common splicing modes of circuit board splicing plates comprise V-CUT, stamp holes and real connection. Wherein, the real connection means that each circuit board is connected through a connecting rib. However, in the current design of the real connection jointed board, burrs are easily generated at the corner positions of the circuit board during board separation, and the burrs are required to be manually polished and removed, so that the board separation efficiency is reduced. Disclosure of utility model In order to overcome the problems in the related art, the application provides a circuit board jointed board, which can avoid burrs at corner positions of the circuit board during board separation and improve board separation efficiency. According to a first aspect of the embodiment of the application, a circuit board jointed board is provided, which is characterized by comprising a plurality of first connecting components and a plurality of circuit boards which are arranged in an array, wherein a first channel is arranged between adjacent circuit boards in a first direction of the array arrangement, a second channel is arranged between adjacent circuit boards in a second direction of the array arrangement, and the first direction and the second direction are mutually perpendicular; The circuit boards are arranged in a 2 x 2 array manner, each four circuit boards are connected through a first connecting component, each first connecting component comprises a first connecting part, a second connecting part and a third connecting part, each second connecting part is positioned at the junction of the first channel and the second channel, the first connecting parts and the third connecting parts are respectively arranged at two sides of each second connecting part extending along the first direction, two side surfaces of each first connecting part and two side surfaces of each third connecting part are respectively connected with one side surface of the circuit board, and the width of each second connecting part in the second direction is smaller than that of each first connecting part in the second direction, and the width of each second connecting part in the second direction is smaller than that of each third connecting part in the second direction; the position, close to the second connecting part, of the connecting part of the first connecting part and the connected circuit board is inwards concave to form a first arc-shaped structure, and the position, close to the second connecting part, of the connecting part of the third connecting part and the connected circuit board is inwards concave to form a second arc-shaped structure. According to the embodiment of the application, the first connecting component comprises the first connecting part, the second connecting part and the third connecting part, the first arc-shaped structure is formed by inwards recessing the connecting part of the first connecting part and the connected circuit board at the position close to the second connecting part, the second arc-shaped structure is formed by inwards recessing the connecting part of the third connecting part and the connected circuit board at the position close to the second connecting part, and the contact angle between the cutting tool and the circuit board can be changed due to the arc-shaped structure, so that the cutting force is more uniformly distributed on the surface of the circuit board, burrs are prevented from being generated at the corner position of the circuit board during board separation, manual burr polishing is not needed, and the board separation efficiency is improved.
