Connectors are called connectors in China and almost cover all manufacturing industries. Especially in the manufacturing industry related to cables and circuit boards, the applications are the most extensive. Pin and female connectors are the most common types of connectors. Many similar connectors can be said to have been converted from a plug-in method similar to that of the Paizhenyu busbar. According to the production and manufacturing needs of different industries, various types of connectors have been derived, mainly divided into three forms: wire to wire, wire to board, and board to board.

The structure of pin and socket is in the form of one male and one female, which can be imagined to be a socket used in daily life, similar to a plug (pin) and a socket (female). According to conventional production and usage requirements, we can usually hear the so-called 127 needle and 2-needle. 0 row needles, 254 row needles, which are different from the spacing between the rows of needles. Similarly, according to different usage methods, there are also different forms such as direct insertion, surface mount, and bent needle. The use of needle and mother connectors can better eliminate connection errors caused by a large number of cable connections, making the entire product more precise.

With The New York Times entering the era of intelligent informatization, the needle production and manufacturing industry is becoming more industrialized, and different industries and usage environments have different requirements for products. The workmanship of consumer electronics needle and mother products is becoming increasingly refined, and the number of needles is also becoming more selective. The actual length and height of the needle arrangement may have customized requirements for different sizes.
