当插针内导体的插针进入插孔时就会使得插孔过度扩张,形变量超出其弹性形变范围,产生塑性变形,导致插孔内导体损坏;相反,如果插针直径过小,当插针和插孔配合时,插针与插孔壁之间的间隙过大,两内导体不能紧密接触,接触电阻变大,连接器的电气性能指标会很差。那么,乐业连接器小编为大家讲解下电连接器插针插孔究竟是如何组成的:

矩形电连接部件组成包括:绝缘体、接触件、壳体

圆形电连接器部件组成包括:壳体、绝缘安装板、接触件。

连接器由插座、插头、附件三部分组成。插座、插头用来固定接触件,插合后连接。附件用来固定电线、保护焊(压)点处不受力,附件通过螺纹或螺钉连接在插头或插上。

圆形连接器的插头与插座之间有螺纹连接、三曲槽卡口连接、推拉式连接、三头螺纹连接、半圆环扣紧等形式;插针插孔矩形连接器插头与插座之间有直接插合、螺钉连接缩紧装置连接等。

USB扩展插针、前面板扩展插针、耳机接口扩展插针……这些我们经常用到的插针,对于经常装电脑的朋友来说,如何连接这些插针可以说是轻车熟路。但是在这个大家已经习以为常看惯了的插针上,也有我们不了解的地方。

一提起“针”这个字,大家的反应都是细长、圆锥形、被扎一下会相当疼。但是主板上的“插孔”还真的不是圆的。大家仔细看的话,会发现主板上的针脚的横截面是方形的,整个一根针的是呈现出立方体的形态。

When the pin of the conductor in the pin enters the socket, the socket will expand excessively, the shape variable will exceed its elastic deformation range, resulting in plastic deformation, which will cause the conductor in the socket to be damaged; on the contrary, if the pin diameter is too small, when the pin and socket cooperate, the gap between the pin and the socket wall is too large, the two inner conductors cannot be contacted closely, the contact resistance becomes larger, and the electrical property of the connector is large The energy index will be very poor. Then, the music connector is compiled to explain how the pin socket of the power down connector is composed:

The components of rectangular electrical connection include: insulator, contact part and shell

The components of circular electrical connector include: shell, insulation mounting plate and contact.

The connector is composed of socket, plug and accessory. The socket and plug are used to fix the contact parts and connect them after being plugged in. Accessories are used to fix wires, protect welding (pressing) points from force, and accessories are connected to plugs or plugs by thread or screw.

The plug and socket of circular connector are threaded, three curved groove bayonet, push-pull connection, three-end threaded connection, half circle ring fastening, etc.; the plug of rectangular connector of pin socket and socket are directly inserted and connected with screw connection and compression device.

USB extension pin, front panel extension pin, headphone interface extension pin These pins we often use, for friends who often install computers, how to connect these pins can be said to be light and familiar. But there are also places we don't know about the pins that we have become accustomed to.

When we mention the word "needle", everyone's reaction is slender, conical, and it will be quite painful to be tied. But the "Jack" on the motherboard is not really round. If you look carefully, you will find that the cross-section of the pin on the motherboard is square, and the whole pin is in the form of a cube.
