The utility model provides a waterproof connecting cable which is suitable for application scenes such as data transmission or equipment power supply and the like and can effectively improve the waterproof grade between a connector body and a cable assembly.

Referring to fig. 2 to 5, in the present embodiment, the waterproof connection cable includes a connector body 1, a cable assembly 2, and a seal ring 3.

The connector body 1 is internally provided with a cable slot 101. The cable assembly 2 comprises a cable body 201 and a cable plug 202 fixedly connected to the end of the cable body 201; wherein the cable plug 202 is inserted into the cable slot 101 and electrically connected to the connector body 1. The sealing ring 3 is positioned between the groove wall of the cable slot 101 and the outer surface of the cable plug 202; the sealing ring 3 includes a plurality of inclined portions 301 connected in sequence, and two adjacent inclined portions 301 are connected to form a positive V-shaped structure 302 or an inverted V-shaped structure 303.

In the waterproof connection cable provided in this embodiment, firstly, the sealing ring 3 is disposed between the groove wall of the cable slot 101 and the outer surface of the cable plug 202, and compared with the structure in which the sealing ring 3 is disposed at the end face of the connector body 1, the contact areas between the connector body 1 and the cable plug 202 and the sealing ring 3 are both increased, so that the sealing performance is better;

secondly, set up sealing washer 3 into the zigzag structure that is arranged by a plurality of positive V-arrangement structure 302 and reverse V-arrangement structure 303 in turn, zigzag structure is equipped with a plurality of V-arrangement grooves, can store dust and steam, so the deformability of sealing washer 3 is stronger.

Therefore, the waterproof connecting cable provided by the utility model can effectively improve the waterproof grade between the connector body 1 and the cable assembly 2, and basically can reach IP68 or even higher.

The cable assembly 2 further comprises a plastic housing 203 surrounding the connection location covering both the cable body 201 and the cable plug 202. Optionally, the plastic housing 203 includes a plastic upper cover 2031 and a plastic lower cover 2032 that are fastened up and down; the plastic upper cover 2031 and the plastic lower cover 2032 are fastened together to form a glue filling cavity 2033. The plastic upper cover 2031 is provided with a glue filling hole 2031a communicated with the glue filling cavity 2033.

The cable plug 202 is provided with a communication groove 2021 which communicates the glue-pouring cavity 2033 to the cable slot 101. The waterproof connection cable further includes a glue filling portion extending from the glue filling cavity 2033 to the cable slot 101 through the communication groove 2021.

Optionally, a positioning groove 2022 is provided on the outer surface of the cable plug 202 for the sealing ring 3 to be snapped into.

Optionally, the sealing ring 3 is made of silica gel. The sealing ring 3 made of the silica gel material has better deformation capability, is high-temperature resistant and is not easy to damage due to heating in the glue filling process.

The waterproof connecting cable provided by the embodiment has the following specific production process:

s10: electrically connecting the cable body 201 to the cable plug 202;

s20: buckling the plastic upper cover 2031 and the plastic lower cover 2032;

s30: sleeving the sealing ring 3 on the positioning groove 2022 of the cable plug 202;

s40: inserting the cable plug 202 with the sealing ring 3 into the cable slot 101;

at this time, under the action of the supporting of the groove wall of the cable slot 101, the sealing ring 3 is pressed and deformed, and the serrated sealing ring 3 is flattened and then is pressed upwards against the groove wall of the cable slot 101 and downwards against the cable plug 202 under the action of the elastic deformation restoring force of the sealing ring, so that a good sealing effect can be provided;

s50: the high Wen Jiaoliao is injected through the glue injection hole 2031a, and the high Wen Jiaoliao enters the cable slot 101 from the glue injection cavity 2033 through the communication groove 2021;

in this process, in theory, air in the cable slot 101 should be discharged from the exhaust hole (a specific glue filling and discharging process belongs to the prior art, so that details are not needed), if the air discharging structure is unreasonable or the glue filling process is controlled improperly, the air in the cable slot 101 cannot be discharged timely, so that air is accumulated on one side of the sealing ring 3 close to the connector body 1, high-pressure air can squeeze the sealing ring 3 towards the direction close to the plastic shell 203, and because the sealing ring 3 is in a zigzag shape, the sealing ring 3 has higher deformability in the axial direction, when the high-pressure air axially squeezes the sealing ring 3, the sealing ring 3 is enabled to be pushed up against the groove wall of the cable slot 101 and be pushed down against the cable plug 202, so that the sealing performance between the connector body 1 and the cable plug 202 is further improved, and negative effects caused by unclean discharge in the glue filling process can be avoided;

s60: and cooling and molding the high-temperature sizing material to obtain the glue filling part.

In summary, compared with the existing connecting cable, the waterproof connecting cable provided by the utility model has the following advantages:

(1) the sealing ring 3 is inserted into the cable slot 101, so that the sealing area is larger, and the sealing performance is stronger;

(2) the sealing ring 3 is in a zigzag shape formed by alternately arranging a plurality of positive V-shaped structures 302 and inverted V-shaped structures 303, so that V-shaped grooves for storing dust and water vapor can be provided, negative influence caused by incomplete exhaust during glue filling can be eliminated, and sealing performance is further improved.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
