The plug shell 21 is sleeved on the outer surface of the plug core 22, and the socket shell 31 is sleeved on the outer surface of the socket core 32, so that the connecting parts of the prefabricated plug 20 and the prefabricated socket 30 can be effectively protected. The core 42 of the cable 40 is disposed inside the sheath 41, and the core 42 is connected to the plug core 22 or the socket core 32 of the connector 10 by welding, winding or pressing, which is not limited herein. The core 42, plug core 22 and socket core 32 are all conductors and when connected, function as a conductive circuit. The cover 50 covers both the cable 40 and the connector 10, and serves to protect the connection portion between the cable 40 and the connector 10. The cover 50 may be a moldable material that is in a liquid state at a high temperature, and the cover 50 in the liquid state is poured onto the connected connector 10 and cable 40 to integrate them. After cooling, the cover 50, the cable 40, and the connector 10 are formed as an integral part. In general, the cable 40 and the connector 10 are covered with only the cover 50, and after a long period of use, the cover 50, the cable 40, and the connector 10 are likely to come loose or have a gap. Thus, the use of the sealing grease 60 solves this problem well.

In one embodiment, as shown in fig. 1, 2, and 6, the balls 24 are disposed inside the coupling ring 23, the steel posts 33 are disposed outside the socket shell 31, and the balls 24 are engaged with the steel posts 33 when the prefabricated plug 20 and the prefabricated socket 30 are coupled. The prefabricated plug 20 is provided with a coupling ring 23, the coupling ring 23 is provided with balls 24, the socket shell 31 is provided with a steel column 33 for clamping the balls 24, and the coupling ring 23 is connected with the plug shell 21 in a sleeved mode. The purpose of the coupling ring 23 is to protect the connection portion of the connector 10 from mechanical or adverse environmental damage. Preferably, the balls 24 may be equally spaced at an angle of 120 degrees on the inner wall of the rotatable coupling ring 23 of the prefabricated plug 20. Three spiral small grooves with the same radian are machined on the outer ring of the buckled prefabricated socket 30 on average according to an angle of 120 degrees, a sunken circular pit larger than the ball 24 is arranged at the top end of each small groove, and a steel column 33 with the diameter smaller than the ball 24 is additionally arranged at the front end of each sunken circular pit.
In one embodiment, as shown in fig. 1, 2, 3 and 5, the prefabricated plug 20 or the prefabricated socket 30 is provided with a pin 11 or a hole 12, respectively; one end of the needle part 11 is a needle body 13, the other end is a connector 14, one end of the hole part 12 is a hole body 15, and the other end is the connector 14; the connecting body 14 is a cylindrical body, and gaps are arranged on two sides of the connecting body for being inserted into the wire core 42 and connected with the wire core by cold press welding. The connector 10 may have a variety of connections between the core 22 or the core 32 and the core 42, typically by soldering, with semi-cylindrical connecting ends to facilitate the application of solder wires. In the present invention, it is preferable to provide the cylindrical connecting body 14 on the needle member 11 or the hole member 12 of the plug core 22 or the socket core 32, so that the connecting body 14 can be connected to the wire core 42 by cold press bonding, and the connecting end thereof is cylindrical, so that the process of processing the cylindrical connecting end into the semi-cylindrical shape can be omitted.
In one embodiment, as shown in fig. 4, the sealing grease 60 is a high temperature bonding sealing grease 61 in a semi-cured state. When the sealing grease 60 is a high-temperature bonding sealing grease 61 in a semi-cured state, the bonding effect is better.
In one embodiment, as shown in fig. 1, 3 and 4, the plug housing 21 or the receptacle housing 31 is provided with a groove structure 16, and the groove structure 16 is provided at the connection between the cover 50 and the connector 10. The groove structure 16 of the plug housing 21 or the socket housing 31 contributes to increase the tensile strength in the axial direction of the connector 10 and to increase the thermoplastic fastness in injection molding prefabrication, i.e., the groove structure 16 contributes to hooking the cover body 50 and is not easily pulled out when the connector 10 is plugged in and pulled out.
In one embodiment, as shown in fig. 1, 3 and 4, the connector 10 is provided with a packing 71 and an expansion ring 72, the plug housing 21 or the socket housing 31 is provided with a flange 70, one end of the flange 70 is connected to the packing 71, and the other end of the flange 70 is connected to the expansion ring 72. The sealing rings 71 and the piston rings 72 have sealing functions and are respectively arranged on two sides of the raised thin-walled circular flange 70, and the components are arranged so that the connector 10 has better sealing performance, namely better waterproof and dustproof performance. When the prefabricated plug 20 is coupled with the prefabricated socket 30, the coupling ring 23 is rotated, the balls 24 arranged in the coupling ring 23 respectively advance along the three grooves on the prefabricated socket 30 to the sunken circular pits at the top ends of the grooves, and meanwhile, the balls 24 are buckled by the steel columns 33. The front end face of the shell of the prefabricated socket 30 is tightly abutted to the sealing ring 71 on the flange 70 in the coupling ring 23, and after the sealing ring 71 is extruded by the end face of the shell of the prefabricated socket 30, the axial rebounding reaction force is generated, so that the three balls 24 on the coupling ring 23 sunk into the sunk circular pit are tightly abutted to the steel column 33 arranged on the groove close to the sunk circular pit.
In one embodiment, the sealing grease 60 has a thickness of 1mm, as shown in fig. 2 and 3. In order to solve the problems of outdoor severe summer and sun exposure, severe cold and erosion caused by wind, rain and rain, sealing grease 60 with the thickness of 1mm is coated on a cable before prefabrication, and when the thickness of the sealing grease 60 is about 1mm, the performance of the sealing grease 60 is better. After curing and aging, the cable 40 is prefabricated into a very firm body with the connector 10 in a mold.
In one embodiment, shown in fig. 1 and 7, pre-fabricated receptacle 30 is a fixed mount receptacle 80. The prefabricated socket 30 of the connector 10 is fixedly installed, so that the prefabricated socket can be individually installed on an operation panel and is convenient to insert and pull.
In one embodiment, as shown in fig. 1 and 2, before injection molding and prefabrication, a sealing grease 60 with a thickness of 1mm is coated on the cable 40 for aging curing, then the connector 10 and the aging cured cable 40 are put into a thermoplastic mold, and a special injection molding machine is operated to perform heat sealing and prefabrication the connector 10 and the cable 40 into a whole. Because the coefficients of thermal expansion and contraction of the thermoplastic material of the injection-molded preform and the outer layer plastic material of the cable 40 are different, the gap is easy to crack after thermoplastic molding. The outer layer of the cable 40 is coated with the sealing grease 60, and after aging curing treatment, thermoplastic prefabrication is carried out. The arrangement is such that the cable 40 and the connector 10 are not gapped after being thermoplastic and are firmly integrated. Fine dust, water and mist can not invade into the connector 10 from the gap, and the dustproof and waterproof protection grade reaches IP66 grade or IP67 grade.
The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
