Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

Referring to fig. 1 and 2, the cable connector 1000 of the present embodiment is adapted to waterproof-seal an incoming cable 200, the cable connector 1000 includes an incoming cable base 100, the cable 200 and a waterproof sealing cover 300, and the waterproof sealing cover 300 covers the base body 10 to complete the housing assembly of the cable connector 1000. The wire inlet base 100 comprises a base body 10, a sealing element 20 and a limiting element 30, wherein a waterproof cavity 11 is arranged in the base body 10, specifically, a retaining wall 13 is integrally formed in the base body 10, the retaining wall 13 and the inner side wall of the base body 10 jointly enclose the waterproof cavity 11, preferably, the retaining wall 13 is bent and arranged, and the retaining wall and the inner side wall of the base body 10 jointly enclose the waterproof cavity 11 with a convex structure.

Referring to fig. 1 to 6, a through hole 12 communicating with the waterproof cavity 11 is formed in a side wall of the base body 10 of the embodiment, the sealing member 20 is sleeved on the cable 200 and is close to a free end of the cable 200, when the sealing member 20 is inserted into the through hole 12 along a penetrating direction of the cable 200, the free end of the cable 200 is driven to extend into the waterproof cavity 11, and as the sealing member 20 and the through hole 12 are assembled in place, a part of the sealing member 20 enters the waterproof cavity 11, and the sealing member 20 completely seals the through hole 12, so as to isolate liquid/vapor from entering the base body 10 from the through hole 12.

Preferably, the end of the sealing member 20 away from the waterproof chamber 11 protrudes outward to form a boss 22, and the diameter of the boss 22 is larger than the diameter of the through hole 12, so that the boss 22 cannot be inserted into the through hole 12, and the sealing member 20 is restricted from excessively entering the through hole 12 by the boss 22. Further, in order to prevent the boss 22 from protruding completely from the outer surface of the base body 10, a groove 121 matched with the boss 22 is formed on the periphery of one end of the penetrating through hole 12 away from the waterproof cavity 11, and when the sealing member 20 is assembled with the penetrating through hole 12 in place, the boss 22 abuts against and is embedded in the groove 121. Furthermore, the thickness of the boss 22 is the same as the depth of the groove 121, so that the boss 22 can be completely embedded in the groove 121 and is flush with the side wall of the base body 10, and the design is more beautiful.

Referring to fig. 2, 4, 5 and 6, the limiting member 30 of the present embodiment has a limiting notch 31, a portion of the sealing member 20 entering the waterproof cavity 11 has a limiting groove 21 for the limiting member 30 to be engaged, and when the limiting member 30 is engaged with the limiting groove 21, the limiting member 30 abuts against the base body 10. Here, the limiting member 30 is selectively snap-coupled to the sealing member 20 through the limiting notch 31 and the limiting groove 21, so that the sealing member 20 is blocked by the limiting member 30 from being withdrawn from the penetrating through-hole 12 in a direction opposite to the penetrating direction of the cable 200 by an external force to cause a waterproof failure. In addition, since the limiting groove 21 is disposed at a portion of the sealing member 20 entering the waterproof cavity 11, and when the limiting member 30 is connected to the sealing member 20 by a snap fit, the limiting member 30 is located in the waterproof cavity 11 and abuts against an inner wall of the base body 10, so as to lock the sealing member 20 in the waterproof cavity 11. At this time, the limiting member 30 and the boss 22 clamp and fix the sealing member 20 on the base body 10 together as shown in fig. 6, and the sealing member 20 excessively enters or exits the penetrating through hole 12 along the penetrating direction of the cable 200 or the opposite direction thereof due to an external force, so that the waterproof failure is caused. Preferably, the inner side of the notch of the limiting member 30 is chamfered to form a guiding bevel 311 to facilitate the insertion of the limiting member 30 into the limiting groove 21.

For better carry out waterproof reinforcement to sealing member 20 and cable 200, waterproof chamber 11 intussuseption is filled with waterproof glue, preferred person, waterproof glue is full of waterproof chamber 11 to make cable 200's free end, locating part 30, sealing member 20 be the integral type structure, improve the stability of structure, in addition, waterproof glue is full of waterproof chamber 11, can make waterproof glue can be complete fill up sealed glue and wear the clearance of putting through-hole 12, the waterproof leakproofness of inlet wire base 100 has further been promoted. In addition, because the waterproof cavity 11 is of a convex structure, the space of the waterproof cavity is smaller than that of the waterproof cavity 11 of a conventional rectangular shape, the using amount of waterproof glue can be effectively reduced, and the convex part of the convex structure reserves the space for the free end of the cable 200 to be placed in as shown in fig. 6, so that the placement of the free end of the cable 200 and the waterproof filling of the waterproof glue on the free end of the cable 200 cannot be influenced.

With reference to fig. 1-6, the sealing element 20 of the wire inlet base 100 of the present invention is sleeved on the cable 200 and close to the free end of the cable 200, when the sealing element 20 seals the penetrating through hole 12, the free end of the cable 200 can be synchronously inserted into the waterproof cavity 11, the assembly is simple, and the penetrating through hole 12 is sealed by the sealing element 20, so as to prevent liquid/gas from entering the wire inlet base 100 from the penetrating through hole 12, the structure is simple, and the waterproof performance is good; in addition, the sealing element 20 partially enters the waterproof cavity 11, and the limiting element 30 selectively limits the motion of the sealing element 20, on one hand, the sealing element 20 is limited in the waterproof cavity 11 by the limiting element 30, and the limiting element 30 blocks the cable 200 from pulling to drive the sealing element 20 to be separated from the through hole 12 due to external force, on the other hand, as the sealing element 20 is sleeved on the cable 200, the sealing element 20 and the cable 200 have a fixed relationship, and when the limiting element 30 blocks the cable 200 from pulling to drive the sealing element 20 to be separated from the through hole 12 due to external force, the relative displacement between the free end of the cable 200 and the waterproof cavity 11 is correspondingly limited, so that the cable 200 is prevented from being damaged by external force pulling to be electrically connected with the.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
