[0002] The quick-connect structure generally refers to a connection method that is easy to install and disassemble quickly. It is widely used in various mechanical equipment and systems. It can improve work efficiency, reduce maintenance time, and save space in some cases.

[0003] In the production process of quick-plug structures, it is often necessary to weld multiple parts together to form a solid whole. Quick-plug structures are often not all made of metal, but also include plastic and other structures. Processing these structures requires the use of welding or hot melt techniques.

[0004] In the existing quick-connect fitting production process, employees need to hold the quick-connect fittings with one hand while operating, and use one hand to hold the welding tool to weld the quick-connect fittings. Especially when welding on electroplated cylinders, it is difficult to achieve assembly line technology and the efficiency is low. Secondly, employees need to hold the cylinder to be welded with one hand during operation, which is prone to certain safety hazards. Utility Model Content

[0009] Optionally, the contact includes a connector and an insulator wrapped around the connector.

[0010] Optionally, a protrusion extends outward from the outer wall of the insulator, and a slot is provided in the connection hole of the connection body. The slot can abut against the protrusion to limit the exposed size of the contact end of the contact.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a quick-insertion structure with the following beneficial effects:

[0016] 1. The utility model provides a quick plug-in so that the contact can be installed in the quick plug-in, and the quick plug-in can be inserted into the connection hole of the connection body. When the connection body is installed on the plastic-sealed end of the cable, the quick plug-in is clamped and fixed. The quick plug-in structure changes the traditional welding method into riveting, which is easier to assemble. At the same time, since no welding is required, the efficiency of the assembly line process can be increased, and the safety hazards during welding can be prevented.

[0017] 2. The utility model has a protrusion extending outward on the outer wall of the insulator, and a slot matching the protrusion is opened in the connection hole of the connection body. When the contact is inserted along one end of the connection hole, after the contact is extended along the other end of the connection hole, the protrusion extending outward on the outer wall of the insulator can abut against the slot. At this time, the contact can no longer extend out of the connection block, thereby limiting the extension size of the contact end of the contact, so that there is no need to consider the extension size of the contact during installation, which speeds up the installation and ensures that the size of the contact is consistent;

[0018] 3. The utility model bends the I-shaped quick plug-in to present a circular ring end, a connecting section and a circular ring end after bending, which can make the quick plug-in easier to produce, and the one-piece molding can increase the firmness of the quick plug-in. After the transition bending of the circular ring end, that is, the two ends of the horizontal end are staggered, the diameter of the circular ring end becomes smaller and can adapt to contacts with smaller diameters. On the contrary, if the spacing between the joints generated by the unclosed state increases, the diameter of the circular ring end becomes larger and can adapt to contacts with larger diameters to meet different usage requirements.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: See Figures 1 to 7According to an embodiment of the utility model, a technical solution is provided: a quick-plug structure, comprising: a contact 1, a connecting body 2 and a quick-plug 4, wherein the contact 1 is suitable for being electrically connected to an electrical device. It should be noted that the contact 1 can be directly inserted into the electrical device to be electrically connected to the electrical device, and the contact 1 can be electrically connected to the cable located in the plastic-sealed end 7 of the cable, and the function of the contact 1 is to connect the electrical device with the cable in the plastic-sealed end 7 of the cable, thereby realizing the function of transmitting power; a connecting hole 3 is provided in the connecting body 2, and the connecting body 2 has a relative outward end and an inner connecting end, and the inner connecting end can be installed in The plastic sealed end 7 of the cable, it should be noted that the plastic sealed end 7 of the cable is the connection between the cable and the conventional electrical equipment, which prevents the cable from bending and damaging the plastic sealed end. The cable in the plastic sealed end 7 of the cable can be electrically connected to the contact 1. The installation method can be that the plastic sealed end 7 wraps the connection body 2 and the quick plug-in 4 and is fixed by hot melting or bonding. During bonding, the connection body 2 and the plastic sealed end 7 can still clamp the quick plug-in 4. During hot melting, the plastic sealed end 7 wraps the connection body 2 and the quick plug-in 4. After cooling, the connection body 2 and the quick plug-in 4 are wrapped by the plastic sealed end 7 and fixed; the quick plug-in 4 includes a ring end 4 01 and the limiting end 402, the contact 1 can be installed in the circular end 401. It should be noted that the connection method between the contact 1 and the circular end 401 of the quick plug-in unit 4 can be a partial threaded connection, bonding or clamping limit. The contact end of the contact 1 partially protrudes from the circular end 401, the circular end 401 of the quick plug-in unit 4 can be inserted into the connecting hole 3 and the limiting end 402 can be against the inner connecting end; when the inner connecting end is connected to the plastic sealing end 7, the limiting end 402 is limited.

[0029] The quick-plug structure of the above structure is adopted. By setting the quick plug 4, the contact 1 can be installed in the quick plug 4, and the quick plug 4 can be inserted into the connection hole 3 of the connection body 2. After the quick plug 4 is inserted into the connection hole 3 of the connection body 2, the limit end 402 of the quick plug 4 abuts against the connection body 2, limiting the quick plug 4 from continuing to extend into the connection hole 3. Then, when the connection body 2 is installed on the plastic-sealed end 7 of the cable, the quick plug 4 is clamped and fixed. The quick-plug structure changes the traditional welding method into riveting, which is easier to assemble. At the same time, since no welding is required, the efficiency of the assembly line process can be increased, and the safety hazards during welding can be prevented. The problem that welding in the existing quick-plug connector production process is difficult to achieve the assembly line process and the efficiency is low is solved. Secondly, the employees need to hold the cylinder to be welded by hand during operation, which is prone to certain safety hazards.

[0030] In this embodiment, the contact 1 needs to be inserted into the electrical device to be electrically connected to the electrical device. In order to prevent the user from touching the connection between the contact 1 and the electrical device and causing safety hazards, the contact 1 is configured as a connector 101 and an insulator 102 wrapped outside the connector 101. In this way, when the connector 101 is inserted into the electrical device, the insulator 102 abuts against the socket of the electrical device to seal the socket, and the user cannot directly touch the connector 101, thereby increasing the safety factor. It should be noted that the insulator 102 can be rubber and plastic commonly used in the art, and the connector 101 and the insulator 102 can be connected by hot-melt wrapping the insulator 102 on the connector 101, or by adhesive fixing. The insulator 102 does not wrap both ends of the connector 101, that is, the connector 101 1. One end that can be inserted into the electrical device and one end that is connected to the wire. The depth of the end that can be inserted into the electrical device matches the electrical device in daily use, and the end that is connected to the wire must be at least partially electrically connected to the wire.

[0031] In the present embodiment, in order to limit the contact 1 from extending out of the connection hole 3 of the connection body 2, the contact 1 has different sizes extending out of the connection hole 3 after production, which affects the use of the contact 1. For example, when the contact 1 extends out of the connection hole 3, part of the connector 101 in the contact 1 protrudes from the insertion hole of the electrical device. When outputting power, part of the connector 101 will come into contact with the air, which may easily leave a safety hazard. When the contact 1 does not extend out of the connection hole 3 enough, part of the connector 101 in the contact 1 cannot be fully inserted into the insertion hole of the electrical device, which affects power transmission and causes poor contact. At the same time, in order to speed up installation, a protrusion 103 extends outwardly on the outer wall of the insulator 102, and a card slot 5 matched with the protrusion 103 is opened in the connection hole 3 of the connection body 2. When the contact 1 is inserted along one end of the connection hole 3, after the contact 1 extends out along the other end of the connection hole 3, due to the protrusion 103 extending outwardly on the outer wall of the insulator 102 3 can abut against the card slot 5, and the contact 1 can no longer extend out of the connecting hole 3, thereby limiting the extended size of the contact end of the contact 1, so that there is no need to consider the extended size of the contact 1 during installation, the contact 1 can be quickly inserted to accelerate the installation efficiency, and the size of the contact 1 can be ensured to be consistent.

[0032] In this embodiment, in order to facilitate production and assembly, the number of protrusions 103 is two, and the protrusions 103 are fan-shaped. If the protrusions are directly extruded from the insulator 102 in the contact 1, the insulator 102 needs to undergo hot-melt extrusion and other processes, and the process needs to be increased. However, the protrusions 103 are produced separately, and only the protrusions 103 need to be fixed to the outer wall of the insulator 102 by hot-melt. The process is simpler and the effect achieved is the same. In addition, considering that the cable in the subsequent plastic-sealed end 7 may need to pass through the protrusions 103 of the insulator 102 and be connected to the connector 101 in the contact 1, a gap is left for easy connection.

[0033] In this embodiment, since the contact 1 needs to be electrically connected to the electrical equipment, its connector 101 also needs to be connected to the wire. In order to facilitate the wire to enter the connecting hole 3 along the connecting body 2 and connect with the contact 1 in the connecting hole 3, a reserved hole 6 is provided on the inner connecting end of the connecting body 2. During installation, the wire can be inserted into the connecting body 2 along the reserved hole 6 to connect the wire to the contact 1. It should be noted that when the connecting body 2 is wrapped by the plastic-sealed end 7 of the cable, the reserved hole 6 needs to be completely wrapped therein, which can reduce the external wear of the cable and make the whole more complete.

[0034] In this embodiment, the quick plug-in unit 4 is in an I-shape before forming, and the I-shape has a wider horizontal end, a narrower horizontal end and a vertical connecting section 403. The wider horizontal end is in a circular ring shape after being bent, that is, the circular ring end 401. After the transition bending, that is, the two ends of the horizontal end are staggered, the diameter of the circular ring end 401 becomes smaller, which can adapt to contacts 1 of different diameters. On the contrary, if the spacing between the joints 8 generated by the unclosure is increased, the diameter of the circular ring end 401 becomes larger, which can adapt to contacts 1 with larger diameters to meet different usage requirements. After the narrower horizontal end is bent in the opposite direction of the bending of the circular ring end 401, it presents an arch bridge shape, that is, the limiting end 402. After the circular ring end 401 of the quick plug-in unit 4 is bent and formed, the top has the joint 8 generated by the unclosure. By bending the I-shaped quick plug-in unit 4, it presents the circular ring end 401 and the connecting section 402 after being bent. 3 and the ring end 40 1, the quick plug-in unit 4 can be more easily produced, and the integral molding can increase the firmness of the quick plug-in unit 4.

[0035] Working principle: first insert the contact 1 along the annular end 401 of the quick plug-in 4, at this time the insulator 102 in the contact 1 abuts against one side of the annular end of the quick plug-in 4, after the contact 1 is installed, insert it together with the quick plug-in 4 along one end of the connecting hole 3 of the connecting body 2, then the contact 1 extends from the connecting body 2 toward one side of the electrical device, when the connector 101 of the contact 1 protrudes from the connecting hole 3, the fan-shaped extension protrusion 103 of the insulator 102 wrapped outside the connector 101 abuts against the card slot 5 provided in the connecting hole 3, and at the same time the connecting section 403 of the quick plug-in 4 fits against the inner wall of the connecting body 2, and the arch bridge-shaped limiting end 402 abuts against the connecting body 2, at this time the size of the connector 101 of the contact 1 extending out of the connecting hole is limited, then the wire in the plastic sealed end 7 of the cable is inserted into the connecting body 2 along the reserved hole 6, so that the wire and the connector 10 1, then the quick plug-in 4 and the connecting body 2 are hot-melt-molded with the plastic-sealed end 7 of the cable, and the plastic-sealed end 7 of the cable and the connecting body 2 are clamped and fixed to the limiting end 402 of the quick plug-in 4, and the installation can be completed. This structure changes the traditional welding method into riveting, which is easier to assemble. At the same time, since no welding is required, the efficiency of the assembly line process can be increased.
