In this embodiment, as shown in fig. 1, fig. 5, do the utility model discloses waterproof plug connector 60, waterproof plug connector 60 forms closed area in order to reach better water-proof effects with corresponding waterproof female seat 70 butt joint back to guarantee relevant electronic product increase of service life in adverse circumstances, so simultaneously, still will realize that this waterproof plug connector can break away from female seat better and provide convenient for electronic product installation, maintenance. The waterproof plug connector 60 comprises a waterproof shell, a crystal head 2, a waterproof ring 3 and a cable 5 connected with the crystal head 2. The front waterproof shell comprises a front shell 1 and a rear shell 4.

Referring to fig. 2 to 5, specifically, the waterproof case is a circular structure, and the front case 1 and the rear case 4 may be formed by injection molding of plastic or may be made of a metal material. The front shell 1 comprises a connecting seat 11, one end of the connecting seat 11 is provided with a clamping end 12 matched and jointed with a female seat and an external thread connecting part 13 which is arranged at the other end opposite to the connecting seat 11 and is connected with the rear shell 4, the external thread connecting part 13 is outwards extended and convexly provided with a plurality of extruding sheets 14 along the wall edge, the plurality of extruding sheets 14 form an annular space 16 for receiving the waterproof ring 3, and the outer edge of the tail end of the plurality of extruding sheets 14 is provided with a joint part 141 butted with the inner surface of the rear shell 4; the connecting seat 11 is internally provided with an accommodating chamber 121 for accommodating the crystal head 2 and a through hole 17 for the crystal head 4 to penetrate, the through hole 17 is communicated with the annular space 16, the size of the through hole 17 is equivalent to that of the crystal head, the crystal head 2 can be freely inserted, and the waterproof ring 3 can be prevented from sliding into the accommodating chamber 121. The rear shell 4 is provided with an accommodating space 41 for accommodating the plurality of squeezing sheets 14 and the waterproof ring 3, the inner wall surface of the accommodating space 41 is connected with an internal thread connecting part 42 of the external thread connecting part of the front shell 1, and the tail end of the rear shell 4 is provided with a conical part 43 for preventing the waterproof ring from sliding out. In addition, the annular surfaces of the front and rear shells are provided with non-slip stripes 111, which is beneficial for tightening or loosening the front shell 1 and the rear shell 4 for convenient use.

The front housing 1 is provided with a button 15 on the annular surface of the connecting seat 11, and the button 15 should be formed by injection molding material to apply force on the button. If the front shell 1 is made of injection molding material, the button 15 can be integrally formed with the front shell 1, but it should be noted that the thickness of the button 15 is thinner than that of the connecting seat 11; if the front housing 1 is made of metal material, the button 15 still needs to be installed on the connecting seat 11 by an assembling structure after being separately molded by injection molding material.

The crystal head 2 comprises a plastic main body 21 and an elastic sheet 22 integrally arranged on the plastic main body 21, the front end of the elastic sheet 22 is buckled in the female seat to be fully jointed, the tail part of the elastic sheet 22 extends outwards in an inclined manner to form a pressing part 221, when the crystal head 2 passes through the through hole 17 and enters the accommodating chamber 121, the crystal head 2 is just clamped on the wall surface of the through hole 17, the pressing part 221 of the elastic sheet 21 is just located under the button and abutted against the inner wall surface of the button 15, as shown in fig. 5, an operator only needs to drive the pressing part 221 to move downwards by applying force to the button, and thus the crystal head 2 can be easily separated from the waterproof female seat 70.

The waterproof plug connector 60 of the utility model rivets the crystal head 2 and the cable 5, directly inserts the crystal head 2 with the cable 5 from the annular space 16, and the crystal head is accommodated in the accommodating chamber 121 through the through hole 17, and the crystal head 2 is exactly firmly clamped with the through hole 17; then, the waterproof ring 3 is sleeved on the cable 5 through the through hole 31 and is pushed into the annular space 16 with force, and the end face of the waterproof ring 3 is abutted against the outer wall surface of the through hole; then, the rear shell 4 is inserted into the plurality of pressing pieces 14 from the rear end and is clamped on the plurality of pressing pieces 14, and the rear shell is screwed and connected to the connecting seat 11 through the internal thread connecting part 42 and the external thread connecting part 13, so that the whole waterproof plug connector 60 is assembled, as shown in fig. 6.

When the rear shell 4 is screwed and connected on the front shell 1, the tail end attaching parts 141 of the plurality of extrusion sheets 14 are abutted to the inner wall surface of the tail end conical part 43 of the rear shell 4, when the rear shell is rotated forcibly, the conical part 43 forcedly presses the attaching parts 141 of the plurality of extrusion sheets 14, so that the plurality of extrusion sheets 14 are stressed to shrink and extrude the waterproof ring 3, the compressed waterproof ring 3 has outward tension, and the waterproof ring 3 is expanded and deformed to be in tight connection with the waterproof shell, so that the waterproof sealing effect of the connector is improved.

Compared with the prior art, the waterproof plug connector 60 of the utility model has obvious advantages, firstly, the waterproof plug connector 60 forms a closed area after being connected with the waterproof female seat 70, the pressing part 221 of the crystal head 2 is just abutted against the button 15, and the pressing part 221 can be driven by applying force to the button 15 to realize the separation of the crystal head 2 and the female seat, thereby greatly facilitating the convenience of the electronic product needing to be overhauled or maintained in the future; secondly, quartzy bandeau cable can be directly from assembling in the preceding shell 1, need not to penetrate the preceding shell alone in with the cable, then can only with quartzy head pressure joint on the cable from the preceding shell front end, fix quartzy head in the preceding shell again, this kind of prior art discloses when the equipment is accomplished if its quartzy head damages can't directly pull out the quartzy head that the waterproof shell more renews, needs wholly to change, brings inconvenience and is unfavorable for the cost-saving for the equipment.

In summary, the button 15 is arranged on the front shell 1, and the elastic sheet 22 can be smoothly separated from the female seat by applying force to the button 15 and pressing the part 221, so that convenience is brought to installation, maintenance or repair of electronic products in severe environment; meanwhile, the size of the through hole 17 formed in the front shell 1 can realize the free insertion of the crystal head 2 and prevent the waterproof ring 3 from sliding into the accommodating chamber 121, thereby facilitating the assembly and saving the cost.

In the above embodiments, the descriptions of the respective embodiments have respective emphasis, and reference may be made to the related descriptions of other embodiments for parts that are not described or recited in detail in a certain embodiment.

It should be noted that the above embodiments can be freely combined as necessary.
