Problems solved by technology

[0002] The blind-mating photoelectric connection between the sub-board and the motherboard in the chassis is a widely used structural form of communication electronic equipment. With the connection density, high speed and diversification of equipment application environments, there are more and more requirements for the cleanliness and dustproof of photoelectric connectors. The higher the temperature, the traditional photoelectric connector has no dust protection device or the dust protection effect is poor, and it is impossible to realize the two-way dust protection of the pins and jacks of the blind mating connector of the mother board and the daughter card board, let alone the two-way dust protection in the process of plugging and unplugging the board. Clean the pins in

Embodiment 1

[0040] see figure 1 with figure 2 As shown, the embodiment of the present invention provides a daughter card connector, which includes a daughter card housing 1 and a first dustproof door 2; the daughter card housing 1 is provided with several hole-end plugs 10 (which may be metal post electrical connection holes or optical fiber jack); one side wall of the daughter card housing 1 is the first side wall 11 and the other three side walls are the second side wall 12, the height of the first side wall 11 is smaller than the height of the second side wall 12; the first anti- The dust door 2 is rotatably connected to the first side wall 11 (as hinged or hinged); the first dust door 2 has an open state and a closed state, and when the first dust door 2 is in the open state, the first anti-dust door The dust door 2 is on the same plane as the first side wall 11, and the end of the first dust door 2 away from the first side wall 11 is flush with the second side wall 12 (such as fig...

Embodiment 2

[0043] The embodiment of the present invention provides a daughter card connector. The difference between this embodiment and Embodiment 1 is that: the first door shaft is rotatably connected to the first side wall 11, and a plurality of first torsion springs are sleeved on the first door shaft. The first dust-proof door 2 is fixedly connected with the first door shaft, and the two legs of the first torsion spring are respectively fixed on the first side wall 11 and the first dust-proof door 2 .

[0044]Due to the elastic force of the first torsion spring, the first dust-proof door 2 is automatically closed during the pull-out process without manual opening and closing, and the opening and closing switching is more automatic, reducing the workload of personnel.

Embodiment 3

[0046] see image 3 with Figure 4 As shown, the embodiment of the present invention provides a motherboard connector, which includes a motherboard housing 3 and a front cover assembly 4; the motherboard housing 3 is provided with a receiving cavity 30 for at least partially receiving the daughter card connector, and On the motherboard housing 3 and located in the receiving cavity 30, there are a number of needle-end plugs 31 (which can be metal post electrical connection pins or optical fiber ferrules) for insertion into the hole-end plug 10; 4 sets of front cover assemblies Located on the motherboard housing 3; the front cover assembly 4 includes a frame body 40 and a second dust-proof door 41 (such as hinged or hinged connection) that is rotatably connected to one end of the frame body 40; the second dust-proof door 41 has an opening state and closed state, when the second dust-proof door 41 is in the open state, the second dust-proof door 41 is located in the accommodatio...

Abstract

The invention discloses a sub-card connector, a mother board connector, a photoelectric connector assembly and a chassis. The sub-card connector includes a sub-card housing and a first dust-proof door; several hole-end plugs are arranged in the sub-card housing; the sub-card housing One of the side walls of the body is the first side wall and the other three side walls are the second side walls, the height of the first side wall is smaller than the height of the second side wall; the first dustproof door is rotatably connected to the first side wall; The first dust-proof door has an open state and a closed state. When the first dust-proof door is in the open state, the first dust-proof door is on the same plane as the first side wall; when the first dust-proof door is in the closed state, the first One end of the dust-proof door near the rotational connection with the first side wall protrudes from the outer surface of the first side wall and forms a protrusion. The invention has a simple structure, effectively prevents dust from the daughter card connector and the mother board connector respectively, and is suitable for the blind insertion environment.
