Description

Electrical connectors that hold circuit boards with ejectors and sockets

technical field

The utility model relates to an electrical connector for circuit boards, in particular to an electrical connector which is applied to electrical equipment with high-frequency characteristics such as computers, and uses ejectors and slots to clamp circuit boards.

Background technique

The traditional slot-type electrical connector is mainly used to guide the insertion of the circuit board of the computer equipment, and can firmly hold the circuit board. Referring to FIG. 1 , generally only one vertically upward guide piece 101 is provided on both sides of both ends of the slot 10 , so that the circuit board inserted into the slot 10 is clamped and fixed by the guide piece 101 . But its guide plate 101 is a fixed structure, therefore, when a slightly thinner circuit board is inserted into the slot, it often shakes, which affects the stability of the high-frequency system, and when the circuit board is slightly larger, it cannot be inserted into the slot , which is a common shortcoming of conventional socket-type electrical connectors.

Therefore, the related industry proposes an improved technical solution of a clamping structure (as shown in FIG. 2 ), which is to pivotally install an ejector 20 at the end of the slot 10 respectively. A groove 201 is provided on both sides of the front end, and a clamping shrapnel 202 protrudes from the bottom of each groove 201. When the circuit board is inserted in the slot, the ejector 20 can be pressed down to tilt up, and at the same time, the The two clamping elastic pieces 202 clamp and fix the circuit board. However, it is known that this type of socket-type electrical connector with ejector 20 is different from the manufacturer of the circuit board and the error of the thickness of the circuit board, so that the two clamping elastic pieces 202 of the ejector 20 cannot effectively play their clamping role. There is no support on the back of the two clamping elastic pieces 202 of the ejector 20, so it is also easy to cause breakage.

In addition, today's computer equipment has entered the era of high-frequency clock design, so it is very easy to generate electromagnetic radiation during operation, which usually affects the stability of the operation of surrounding equipment, and the current socket-type electrical connection seen in the market There is no preventive design for electromagnetic radiation (EMI), so high-frequency computer equipment, component operation oscillation and electromagnetic radiation interference generated by it are very easy to cause loose plugs and affect its performance.
