[0023] The present invention will be described in detail below with reference to the accompanying drawings.
[0024] like Figures 1 to 3 As shown, the printed circuit board connector without plug-in contacts includes a straight connector 1 and a side connector 2. In the figure, both sides of the straight housing 101 of the straight connector 1 extend outward to form a straight connection platform 102 with holes. The middle part of the straight housing 101 is recessed to form a straight sinking platform 103. The middle part of the straight sinking platform 103 is hollowed out to form a straight cavity 104. A straight multi-hole socket 105 is installed inside the straight cavity 104. Interconnected straight terminals 106 and straight connectors 107 are equidistantly installed on the straight multi-hole socket 105. A straight connection bolt 108 is detachably installed in the through hole of the straight connection platform 102 with holes. The straight connection bolt 108 is used to connect the printed board 3.
[0025] like Figures 4 to 6 As shown, both sides of the side shell 201 of the side connector 2 extend outward to form a side perforated connecting platform 202, the middle part of the side shell 201 is recessed to form a top sinking platform 203, and the side shell 201 is provided with a top cavity 204 and a side cavity 205 which are interconnected, and a side multi-hole socket 206 is installed inside the top cavity 204 and the side cavity 205, and the side multi-hole socket 206 is provided with side terminal posts 207 equidistantly installed in the horizontal direction, and the side multi-hole socket 206 is provided with side connecting heads 208 equidistantly installed in the vertical direction, and the inner ends of the side terminal posts 207 and the side connecting heads 208 are connected to each other, and a side connecting bolt 209 is detachably installed in the through hole of the side perforated connecting platform 202, and the side connecting bolt 209 is used to connect the printed board 3.
[0026] In the figure, the height difference between the vertical sink 103 and the top sink 203 ranges from 0.4mm to 0.6mm. The outer profile width L1 of the vertical connector 1 ranges from 22 to 25mm, and the top plug-in height L2 of the vertical connector 1 ranges from 6 to 8mm. The column spacing L3 of the vertical connector 107 ranges from 1.1mm to 1.3mm, and the row spacing L4 of the vertical connector 107 ranges from 1.0mm to 1.2mm. The outer profile width L5 of the side connector 2 ranges from 24 to 25mm, and the top plug-in height L2 of the side connector 2 ranges from 6 to 8mm.
[0027] It should be noted that the total height of the plug connector can meet the technical requirement of not more than 8 mm. The plug is a product with a wire, and the socket is a straight printed circuit board product. The working current is 3A and the dielectric withstand voltage is 600V. This design breaks the original way of thinking and does not use pin or socket contacts in the MDC series products. One end of the product tail is set as a terminal, and the other end is a side outlet or a straight outlet. The thrown wire and the conventional connector form a cable assembly for connecting the cabin to the outside.
