The terminal set is fastened and fixed inside the insulating seat body, and the wire and the terminal set are connected at one end, and then the covering body is wrapped. Covering the terminal block and the wire connection to achieve the positioning and insulation functions, but the connectors are made of a hard material due to the insulating seat system, and the covering body is a soft material, and the two materials are closely attached to each other, but after using for a period of time, The flexural deformation and physical properties of the two materials are too different, so that a gap is formed between the two materials and peeled off, causing moisture to penetrate, causing the terminal group to be wetted and affecting the transmission efficiency.

In our patent No. M443292, it is a waterproof connector module comprising an insulating core having a plug portion and a support portion, and a plurality of conductors integrally molded with the insulating core, and a support portion of the insulating core is provided with a majority a flange and a groove, after the conductor extends from the soldering end of the support portion and the wire is soldered, the support portion, the soldering end and the wire are covered by a protective sleeve; but the insulating core and the protective sleeve of the patent No. M443292, Although the flange and the groove are used to enhance the bonding effect of the protective sleeve, the insulating core is actually a hard colloid, and the protective sleeve is a soft colloid, and the difference between the flexural deformation and the physical properties of the two materials is still excessive. After using it for a while, There will be gaps and poor waterproofing.

The purpose of the present invention is to provide an improved structural structure of an electrical connector that can provide better combined positioning and good waterproof performance, while having a compact structure and convenient assembly.

In a preferred embodiment of the present invention, there is a structural improvement of an electrical connector, the electrical connector comprising: a rubber core having a first end and a second end, the inner end having a first end The assembly space is disposed at the second end, and a ring groove is disposed at a periphery of the second end.

A sleeve is formed of metal or hard plastic, and has a lumen body, one end of which is a combined end, the other end is a free end, the combined end and the rubber core are sleeved, and the ring groove is tightly wrapped The inner cavity receives the external terminal and the wire, so that the tail end of the wire is exposed to pass through the free end, and the inner cavity including the external end and the wire has a gel filling.

A coating layer is a gel which is coated with a core portion and a sleeve by a molding operation.

An embodiment of the present invention includes a structural improvement of an electrical connector, wherein the electrical connector is either a male or female.

Another embodiment of the present invention includes a structural improvement of an electrical connector in which the combined end and the core portion of the sleeve are sheathed by a riveting or stamping process to tightly wrap the ring groove.

A further embodiment of the present invention includes a structural improvement of an electrical connector, wherein the electrical connector is a male connector having a rotatable nut nested around a first end of the rubber core portion. The nut is coupled to the female connector of another mating electrical connector.

Yet another embodiment of the present invention includes a structural improvement of an electrical connector, wherein the electrical connector is a female connector, the sleeve of which covers the rubber core portion, and the sleeve is at the first end of the rubber core portion. The inner rim is provided with a threaded section that is connected to the male connector of the mating electrical connector.
