Abstract

The utility model discloses a network socket connector with a mistake-proof prevention structure, which is composed of an insulating body, a terminal module, a shielding casing and a mistake-proof structure, wherein the mistake-proof structure is integrally formed with the insulating body and comprises connecting parts which are shaped at left and right sides of the insulating body, and the connecting part is forwards extended with an elastic trip to an insertion interface direction of the insulating body. The end of the elastic trip is integrally extended with shielding plates and contact pressing plates which are parallel, the distance between the shielding plates at both sides is about the width of a telephone line plug and the distance between the contact pressing plates at both sides is about the width of a network line plug. Therefore, when the telephone line plug is inserted into the network socket connector by mistake, the telephone line plug can be blocked by the shielding plates and can not be successfully inserted into the network socket connector. When the correct network line plug is inserted, the plug can firstly and upwards push and press the contact pressing plate, so the shielding plates can also upwards move with the contact pressing plate, the network line plug can not be blocked by the shielding plates, therefore the plug can be successfully inserted on the network socket connector.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

Please refer to shown in Figure 1ly, this network socket connector 10 is that embodiment is illustrated with RJ-45 type network socket connector.Network socket connector 10 includes an insulating body 1, insulating body 1 front side has an interface 11 that supplies RJ-45 type network wire plug 20 (being shown in Fig. 5) to plug, and one terminal module 2 is installed toward in from insulating body 1 rear side, this terminal module 2 is made of a terminal base 21 and a plural conductive terminal 22 that is the L type, these conducting terminals 22 are that the one ejection formation is on terminal base 21, in addition, be coated with a shielding casing 3 in insulating body 1 outside, shielding casing 3 front ends also have an interface 31 that supplies RJ-45 type network wire plug 20 to plug.

Please refer to Fig. 2, shown in 3, feature of the present utility model is provided with error-proof structure 4 in network socket connector 10, error-proof structure 4 is one-body molded with insulating body 1, in an embodiment, insulating body 1 rear wall respectively forms a junction 41 near the place, the left and right sides of top, connecting portion 41 extends forward towards interface 11 directions of insulating body 1 and is provided with flexure strip 42, flexure strip 42 ends then one extension are provided with shielding plate arranged side by side 43 and compress sheet 44, shielding plate 43 is to extend vertically downward, end then has a guide ramp 441 before compressing sheet 44, and the distance X that the shielding plate of the left and right sides is 43 is about telephone line plug 30 (will describe in detail again among Fig. 4) width, the distance Y that the left and right sides compresses 44 of sheets then is about network wire plug 20 width, utilizing both sides to compress the grafting stroke of the distance limit telephone line plug between sheet, and by shielding plate prevent telephone line plug misplug into.

In addition, insulating body 1 is provided with short slot 12 at the end face place of corresponding error-proof structure 4, moves spatial accommodation for error-proof structure 4 by roof pressure up the time.

Please refer to shown in Figure 4, when being inserted in telephone line plug 30 (for example RJ-11 type) mistake in the network socket connector 10, because both sides compress distance Y between the sheet 44 greater than telephone line plug 30 width, telephone line plug 30 can't be touched compress sheet 44, and can touch the shielding plate 43 that both sides are located, now make telephone line plug 30 sheet 43 that directly is blocked withstand and can't be inserted in smoothly in the network socket connector 10, to form a fool proof effect.

Please refer to shown in Figure 5, when correct network wire plug 20 is inserted, the distance Y that both sides compress between the sheet 44 is just identical with network wire plug 20 width, so along with network wire plug 20 plugs toward in, and utilize the guiding that compresses sheet 44 front side guide ramp 441, and up roof pressure compresses sheet 44 (as solid line among the figure partly), the shielding plate 43 that makes and compress sheet 44 one also and then up is moved to short slot 12 places, make network wire plug 20 sheet 43 that can not be blocked withstand, and can be plugged on smoothly on the network socket connector 10.

Via after the explanation of above structure as can be known, the network socket connector 10 of the utility model can utilize the setting of error-proof structure 4, and make in the unlikely network socket connector 10 (RJ-45 type) that misplugs non-coupling of telephone line plug 30 (RJ-11 type), to avoid damaging the conducting terminal 22 in the network socket connector 10, keep good in order to do the electrical characteristic that makes network socket connector 10.In other words, for larger-size plug, just can't insert less socket originally; But, for less plug, but might misplug in the bigger socket, so the utility model provides error-proof structure, in case less plug misplugs in the bigger socket.
