Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a flip-cover contact type connector. Background Art

[0002] FPC is also called flexible printed circuit board, or flexible circuit board for short. Due to the many advantages of flexible circuit boards, such as space saving, light weight and high flexibility, more and more electronic products (such as mobile phones, tablet computers, etc.) are beginning to use flexible circuit boards. In the process of using flexible circuit boards, it is necessary to match the flexible circuit boards with connectors to realize signal transmission.

[0003] In the prior art, after the flip cover connector fixes the contact piece of the flexible circuit board, it is not convenient to lock the flip cover, which causes the flip cover to easily pop out of the flip cover slot by itself, thereby causing the electrical connection of the flexible circuit board to fail. Therefore, we have introduced a flip cover contact connector. Utility Model Content

[0004] The utility model aims to provide a flip cover contact connector, which can prevent the flip cover from popping out by itself, improve the stability of the contact connection of the flexible circuit board, and solve the problems raised in the above background technology.

[0011] Preferably, one end of the limiting rod away from the sealing plate is configured as a round head.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The flip cover contact connector is provided with a flip cover, a pull ring, a spring, a fixing rod, an elastic contact piece and a limiting rod. The flexible circuit board contact piece is inserted into the accommodating cavity, and the pull ring is pulled. The pull ring drives the flip cover to rotate and makes the elastic contact piece abut against the flexible circuit board contact piece. At this time, the spring pushes the strip hole and drives the limiting rod on the sealing plate at one end of the flip cover to engage with the limiting groove, which can prevent the flip cover from popping out by itself and improve the stability of the connection of the flexible circuit board contact piece.
