Description

Terminal Block

The present invention relates to a terminal block, and more particularly to a terminal block for mounting on a circuit board for electrical connection of other electronic components.

Many electronic components are disposed on the circuit board devices of many electronic products. In order to make these electronic components easy to install and disassemble, a plurality of terminal blocks are usually electrically connected to the circuit board body, and then the electronic components are electrically connected. The connection is set to the terminal blocks. At present, the terminal block structure generally comprises a columnar or L-shaped insulator, and a plurality of conductive pins which are inserted and fixed to the insulator.

The manner in which the terminal blocks are electrically connected to the circuit board body is mainly to insert the conductive pins of each terminal block into the conductive sockets of the circuit board body, and then the terminal terminals have been inserted. The circuit board body is transferred to the tin furnace to electrically connect the conductive pins of the terminal blocks to the circuit board body. However, since the terminal blocks are mainly erected on the circuit board body through the conductive pins that are inserted into the circuit board body, the diameters of the conductive sockets are generally larger than the diameters of the conductive pins, so that the transfer is performed. When the main body of the circuit board passes through the tin furnace, the conductive pins cannot provide a stable supporting effect, and the terminal seat is likely to be dumped or skewed, thereby affecting the production yield of the circuit board device.

Accordingly, it is an object of the present invention to provide a terminal block that improves at least one of the disadvantages of the prior art.

Therefore, the terminal block of the present invention is suitable for being disposed on a circuit board body, and the circuit board body is provided with a plurality of conductive jacks penetrating vertically. The terminal block comprises a seat body of an insulating material, and a plurality of spaced-apart conductive pins fixed to the seat body. The base body has a base portion for being stacked on the top surface of the circuit board body, and a protruding portion projecting upward from the top surface of the base portion. The width of at least one of the left and right sides and the front and rear sides of the protruding portion is smaller than the width of the corresponding side of the base portion. Each of the conductive pins has a plug-in section that extends downwardly from the bottom surface of the base portion and is inserted into one of the conductive insertion holes, and an outer connecting portion that protrudes outside the protruding portion.

The utility model has the advantages that the structure of the base portion of the base body is larger than the width of the protruding portion, so that the entire terminal block can be more stably disposed on the circuit board body, so that the circuit board body can be improved to carry the The stability of the terminal block when passing through the soldering furnace makes the entire terminal block difficult to tip or skew, which helps to improve the processing quality of the manufactured circuit board device.

Since the base portion 31 is in the shape of a plate, and the width of the outer connecting portion 42 in the protruding direction of the conductive pins 4 is larger than the width of the straight portion 321 of the protruding portion 32, the protruding portion 32 can be ensured. The center of gravity may fall within the width of the base portion 31, so that the entire terminal block 200 can be stably stacked on the circuit board body 900, and the positioning effect generated by the positioning posts 35 can be matched to further improve the setting on the circuit. Stability on the board body 900. Therefore, during the process in which the circuit board body 900 carries the terminal block 200 through the tin furnace, the terminal block 200 can be stably and swayably positioned on the circuit board body 900, thereby contributing to improving the production yield of the circuit board device. .
