When the plug 50 is inserted into the insertion hole 11, the elastic arm 41 is pressed against the plug 50, and the shielding plate 30 interlocking with the elastic arm 41 shields the entrance of the insertion hole 11. Accordingly, the electronic device 20 is exposed, and the plug 50 includes an elastic member 40 that can communicate with the electronic device 20.

  As shown in FIGS. 1 and 2, a receiving hole 13 communicating with the insertion hole 11 is recessed at the rear end of the main body 10, and the signal output end 21 of the electronic device 20 is connected to the insertion hole 11. The electronic device 20 is accommodated in the accommodation hole 13 so as to be aligned with each other. A fitting hole 14 is provided at the front end of the main body 10, and the electronic device 20 is stably positioned by a rear cover 15 connected to the fitting hole 14.

A positioning pin 16 protrudes from the bottom of the main body 10, and the positioning pin 16 is inserted into a fixing hole provided in one circuit board (not shown), so that the main body 10 is stably provided. Positioned.
In the connector with a built-in dustproof device of this embodiment, the electronic device 20 is an optical fiber signal transmission device, that is, the electronic device 20 is an optical fiber connector.

  Please refer to FIG. 1 to FIG. The elastic element 40 has a fixed piece 42 fitted in the fitting groove 17 of the main body 10, and an elastic arm 41 extends from the fixed piece 42, and the elastic piece 41 is inserted into the insertion hole 11 of the main body 10. After the middle stage 412 of the arm 41 is inserted, the free end 411 of the elastic arm 41 is connected to the fixing hole 31 of the shielding plate 30 so that the shielding plate 30 can be interlocked.

  In the connector with a built-in dustproof device of this embodiment, two shielding plates 30 are slidably provided in the slide groove 12 of the main body 10, and the two shielding plates 30 are fitted in the main body 10. Each of them is linked to an elastic arm 41 in the elastic element 40. When the two shielding plates 30 are always in contact with each other to close the insertion hole 11 of the main body 10 and the plug 50 is inserted into the insertion hole 11, When the elastic arm 41 of the elastic element 40 is pressed by the plug 50, the two shielding plates 30 interlocking with the elastic arm 41 do not shield the entrance of the insertion hole 11, and as shown in FIG. 50 can communicate with the electronic device 20.
