Description
Technical Field
[0001] The utility model relates to the field of building block toys, in particular to a sliding contact structure of building block terminals. Background Art
[0002] With the improvement of living standards, baby carriage building block products have become popular in ordinary families. Since the users of building block car products are children, the assembly feel of each circuit connector of building block car products is very important. If the assembly position is too tight, the child will not have enough strength to buckle it, and if it is too loose, the contact point is prone to poor contact. At present, the circuit contact terminals of general building block cars are electrically connected by plugging. The contact terminals need to be inserted into the sockets of the mainboard box. The sockets are provided with a tight-fitting structure. After being vertically inserted into place, the power can be turned on by relying on the pins on the socket to contact the contact pieces on the contact terminals. If the same set of signal outputs is required, another contact terminal can be added to the contact terminals. The defects of the above-mentioned traditional building block car contact terminals are: due to the vertical insertion fixation, the plug and the socket need to be tightly fitted. If they are loose, it is easy to have poor contact or fall out. If they are too tight, it is inconvenient to assemble. The mold accuracy requirements are very high. The electrode contact pieces also need special tools for pressurized assembly. The production process is complicated. There is side contact between the contact pieces and the pins. The material requirements for the spring pieces are very high. The downward deformation of the contact surface is only about 0.3mm. When assembling, they need to be fully installed in place to fully contact, which is inconvenient to assemble. Utility Model Content
