電連接器插針插孔究是由什么組成的？
當插針內(nèi)導體的插針進入插孔時就會使得插孔過度擴張，形變量超出其彈性形變范圍，產(chǎn)生塑性變形，導致插孔內(nèi)導體損壞；相反，如果插針直徑過小，當插針和插孔配合時，插針與插孔壁之間的間隙過大，兩內(nèi)導體不能緊密接觸，接觸電阻變大，連接器的電氣性能指標會很差。那么，樂業(yè)連接器小編為大家講解下電連接器插針插孔究竟是如何組成的：
矩形電連接部件組成包括：緣體、接觸件、殼體
插針插孔
圓形電連接器部件組成包括：殼體、緣安裝板、接觸件。
連接器由插座、插頭、附件三部分組成。插座、插頭用來固定接觸件，插合后連接。附件用來固定電線、保護焊（壓）點處不受力，附件通過螺紋或螺釘連接在插頭或插上。
圓形連接器的插頭與插座之間有螺紋連接、三曲槽卡口連接、推拉式連接、三頭螺紋連接、半圓環(huán)扣緊等形式；插針插孔矩形連接器插頭與插座之間有直接插合、螺釘連接縮緊裝置連接等。
USB擴展插針、前面板擴展插針、耳機接口擴展插針……這些我們經(jīng)常用到的插針，對于經(jīng)常裝電腦的朋友來說，如何連接這些插針可以說是輕車熟路。但是在這個大家已經(jīng)習以為?？磻T了的插針上，也有我們不了解的地方。
一提起“針”這個字，大家的反應(yīng)都是細長、圓錐形、被扎一下會相當疼。但是主板上的“插孔”還真的不是圓的。大家仔細看的話，會發(fā)現(xiàn)主板上的針腳的橫截面是方形的，整個一根針的是呈現(xiàn)出立方體的形態(tài)。

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.
