Detailed Description

The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.

A printed circuit board (Printed circuit boards, abbreviated as PCB), also known as a circuit board or printed circuit board, is a provider of electrical connections for electronic passive devices. With the rapid development of electronic technology, printed circuit boards are widely used in various fields, and almost all computing devices include corresponding printed circuit boards. The adoption of the printed circuit board has the main advantages of greatly reducing wiring and assembly errors and improving the automation level and the production labor rate.

Signal integrity (SIGNAL INTEGRITY, SI for short) refers to the quality of a signal on a transmission path, which may be a common wire, may be an optical device, or may be other medium. A signal having good signal integrity means having the voltage level values that must be reached when needed. Poor signal integrity is not caused by a single factor, but rather is caused by a combination of factors in the system design.

Surface mount technology (Surface Mounted Technology, SMT for short), also known as surface mount technology or surface mount technology, is one of the most popular technologies and techniques in the electronics assembly industry. It is a circuit mounting technology for mounting non-pin or short-lead surface-assembled components (also called sheet-like components) on the surface of printed circuit board (Printed circuit boards, abbreviated as PCB) or the surface of other base plate, and adopting reflow soldering or dip soldering method to make welding assembly.

Golden finger (Connecting finger) is the generic name for gold-plated connectors that run on the edge of the PCB. For example: the part of the memory bar, the part of the display card and the display card slot, the part of the optical module and the optical module connector, and the like are inserted into each other, and all signals between the two parts are transmitted through golden fingers. The gold finger is composed of a plurality of golden yellow conductive contact pieces, and is called as a gold finger because the surface of the gold finger is plated with gold and the conductive contact pieces are arranged like fingers. The gold finger is actually formed by repeating a layer of gold on the copper-clad plate through an electroplating process, because the gold has extremely high oxidation resistance, the internal circuit can be protected from corrosion, the conductivity is extremely high, the signal loss is not caused, meanwhile, the gold has extremely high ductility, the contact area between the contacts can be larger under proper pressure, the contact resistance can be reduced, and the signal transmission efficiency is improved.

As described in the background art, the connection between the back plate and the single plate can adopt the scheme of connecting the golden finger with the golden finger connector to reduce the loss and improve the signal integrity. However, the golden finger and the golden finger connector have higher precision requirements for plugging and unplugging; and the golden finger connector attached to the surface of the plate body is easy to be knocked or even damaged by the golden finger in the process of inserting and pulling out the golden finger. Therefore, how to ensure the plugging accuracy of the golden finger and the golden finger connector, and the stability and reliability of the plugging of the golden finger and the golden finger connector become the problems to be solved.

Accordingly, the present application provides a connector housing that can be used to mate with a connector (e.g., a golden finger connector) disposed on a board. Specifically, the connector housing includes a housing body, a guide portion disposed on the housing body, and a connecting portion disposed on the housing body. The connecting part is used for fixing the connector housing on the plate body, and the housing is used for housing and limiting the connector, so that the mounting stability of the connector can be ensured, and further, the connector can be prevented from being knocked to be askew or damaged by the connector in the process of being plugged with the connector (such as a golden finger), and the plugging stability and reliability of the connector and the connector are ensured. The guide part is used for guiding when the connector is inserted with the plug connector, so that the plug connector and the connector are guaranteed to be plugged with each other with precision, and the reliability of the electrical connection between the plug connector and the connector is improved.

It can be appreciated that the connector housing provided in the embodiment of the present application may also be applied to other connectors and connectors to improve the plugging accuracy.

In the first aspect, the guide inclined surface 3112 can reduce the probability of the golden finger 210 striking the golden finger connector 320, and avoid the golden finger connector 320 from being damaged due to the insertion and extraction striking; in the second aspect, the guiding inclined surface 3112 may guide the golden finger 210 during insertion into the socket 321 of the golden finger connector 320, so as to ensure smooth and accurate insertion of the golden finger 210 into the socket 321 of the golden finger connector 320; in the third aspect, the end of the guide inclined surface 3112 near the socket 321 of the golden finger connector 320 does not block the socket 321 of the golden finger connector 320, so as to ensure that the golden finger 210 can be smoothly inserted into the socket 321 of the golden finger connector 320.

The distance L between one end of the guide inclined surface 3112 near the insertion port 321 of the gold finger connector 320 and one side of the insertion port 321 of the gold finger connector 320 near the guide inclined surface 3112 is in the range of 1mm to 5mm. Illustratively, the spacing L between the end of the guide inclined surface 3112 near the insertion opening 321 of the gold finger connector 320 and the side of the insertion opening 321 of the gold finger connector 320 near the guide inclined surface 3112 may be set to be 1mm, 2mm, 3mm, 4mm, 5mm, or any value between 1mm and 5mm according to actual needs.

The surface of the guide inclined surface 3112 facing the golden finger connector 320 (i.e., the first surface 3117 of the guide inclined surface 3112) may have a gap with the golden finger connector 320, so that when the golden finger 210 impacts the guide inclined surface 3112, the guide inclined surface 3112 will not directly transmit force to the golden finger connector 320, so that the guide inclined surface 3112 may play a role in damping and buffering, thereby being beneficial to better protecting the golden finger connector 320 and avoiding the golden finger connector 320 from being damaged due to insertion and extraction impact.

In some examples, guide ramp 3112 may be disposed one revolution around the edge of first opening 3111 (see fig. 2) to protect the circumference of socket 321 of golden finger connector 320 and guide golden finger 210.

In other examples, the guide inclined surface 3112 may be disposed on a side edge of the first opening 3111 near the board 100 and a side edge of the first opening 3111 far from the board 100 according to practical requirements, so as to protect upper and lower sides of the socket 321 of the golden finger connector 320 and guide the golden finger 210.

The edge of the guide inclined surface 3112 near the socket 321 of the golden finger connector 320 is rounded to ensure that the edge of the guide inclined surface 3112 does not scratch the golden finger.
