Description

  The present invention relates to a safety structure of a plug, and an elastic latch of a plug body is engaged with a movable lid, so that the plug is not easily pulled out, thereby ensuring the safety of network data transmission. Further, the key moves to the rear in conjunction with the movable lid, and the related technical area of the pressed state is recovered by the elastic latch of the plug body.

The plug is provided with an elastic latch, and the plug is inserted into a jack for electrical connection. Also, when unplugging the plug, the elastic latch on the plug must first be pressed down and then pulled out and removed from the jack. Further, when the data transmission is performed after the plug is inserted into the jack, if the elastic latch of the plug is accidentally pressed down and comes out of the plug, the data transmission is interrupted and a serious problem occurs.

A prior art connector includes a housing and a housing body above which a latch is installed, and the latch includes a handle and both shoulders. (shoulder) is provided. A second latch is movably installed below the handle, and a wedge part of the second latch holds the latch by moving a second latch forward by a slide. Thus, there is one that prevents the latch from being pressed downward (see Patent Document 1 as an example).

Another conventional technique is that the locking tongue support supports the connector's elastic tongue and is positioned by the elastic latch so that it cannot be pressed down (e.g. Patent Document 2). This retaining mechanism engages with an engagement portion on the body and localizes. In addition, a release arm is provided on the rear side.

Another example is that a locking tongue support supports an elastic latching tongue of a connector and is positioned by the elastic latching so that it cannot be pressed downward (for example, Patent Document 3). reference). In addition, a retaining mechanism is localized by engaging with an engagement portion on the body. Furthermore, in this proposal, the key unlocks the retaining mechanism and recovers the state where the elastic locking tongue of the connector can be pressed downward.

The front side of the movable lid 4 above the insertion stop lump 41 is further provided with an inclined surface portion 412 so that the elastic latch 11 of the plug body 1 engaged by the user with the insertion stop lump 41 is locked. Since a jack (not shown) can be inserted at the time of use, it has good elasticity and forgiveness in use function.

When a stop convex point 46 is further installed above the movable lid 4 and the movable lid 4 is pulled backward together with the insertion stop lump 41 (see FIG. 4), the rear end 411 above the insertion stop lump 46 is supported in front. The stopper 31 is stopped by the stop wall 315 of the frame 31. At the same time, the stop convex point 46 is fixed and positioned, so that it does not easily shake or move, so the elastic latch 11 of the plug body 1 is smoothly pressed downward. Is done.

Both side walls (insertion bases) 313 for supporting the movable lid 4 of the front support frame 31 of the protective cover body 3 are molded from a PC hard material, and the protective cover body 32 is molded from a PVC soft material. Sex and appearance have both performance requirements and aesthetics.

Since the front support frame 31 of the protective cover body 3 is connected and fixed after being pressed by the wire block 10 (see FIG. 11) of the plug body 1, there is no need to mold again, installation is simple, and labor is reduced. Save work time.

The design of the key 5 is difficult to imitate because the interlocking tank 51 has an inner wall surface 511 (that is, a smiling curve) recessed in an arc shape.

Since the time space when the key 5 is inserted into the insertion tank 44 of the movable lid 4 is limited, the engagement mass 52 of the key 5 is easily and stably engaged with the engagement tank 441 (see FIGS. 3, 7 and 7). When the key 5 is pulled backward together with the movable lid 4 (see FIG. 4 and FIG. 13), the key 5 can be released at the same time, and the space becomes larger and the bottom of the movable lid 4 has elasticity (otherwise 15), the latching mass 52 of the key 5 can be easily removed (see FIG. 14 in addition), and when it is pulled later, the freely-movable direct squeezing key 5 can be directly and smoothly extracted, so that it is easy and convenient to use.
