Abstract
Description
Technical Field
[0001] The utility model relates to a plastic terminal, in particular to a plastic terminal with insulation protection, belonging to the technical field of plastic terminals. Background Art
[0002] Plastic terminals are terminals made of plastic materials and are mainly used in electrical connectors to connect wires and cables. Plastic terminals are usually made of materials with good insulation properties and can ensure the stability and safety of electrical connections under different environments and conditions. Due to their material properties, plastic terminals are widely used in home appliances, automobiles, electronic equipment, industrial automation and other fields.
[0003] In existing plastic terminals, the insulator on the plastic terminal is connected to the metal part, and then the conductor on the wire is inserted into the metal part of the plastic terminal. The conductive effect of the metal part enables conductivity between different wires. However, when the plastic terminal is in a high temperature or high corrosion environment, the shape of the insulating part on the plastic terminal will undergo a certain deformation. Once the shape of the plastic terminal changes, it may cause a certain gap between the plastic terminals, or the connection relationship between the two wire conductors will no longer be stable. The gap will also increase the risk of the conductor contacting the outside world. After contacting some conductive impurities, a short circuit may occur in the line, which may also cause leakage or corrosion between the two conductors, and then cause a safety accident. At this time, the plastic terminal needs to be replaced and reused, and replacing the plastic requires contact with the wire conductor, which is a cumbersome operation. Directly replacing the plastic terminal will also increase the cost of connecting the line.
[0004] Therefore, there is an urgent need to improve the plastic terminal with insulation protection to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION
[0027] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0028] like Figures 1-10 As shown, the plastic terminal with insulation protection provided in this embodiment includes a plastic terminal body 1 and an outer shell 2. The outer shell 2 is composed of an upper shell 201 and a lower shell 202. The outer shell 2 is arranged on the outside of the plastic terminal body 1 and is in contact with the plastic terminal body 1. Both sides of the upper shell 201 and both sides of the lower shell 202 are provided with raised portions 3, and the raised portions 3 on the upper shell 201 are in movable contact with the raised portions 3 on the lower shell 202. The plastic terminal body 1 and the outer shell 2 are both made of insulating materials.
[0029] The fixing assembly is used to fix the upper shell 201 and the lower shell 202, and to splice the two parts of the outer shell 2, so as to facilitate timely replacement of the outer shell 2 when it is damaged. The fixing rod assembly facilitates the fixed connection of the upper shell 201 and the lower shell 202, and after being fixedly connected, the upper shell 201 and the lower shell 202 will fit tightly on the plastic terminal body 1 and will not fall off easily.
[0030] The plastic terminal body 1 is provided with a connecting component for electrically connecting two wires. The main function of the plastic terminal body 1 is to electrically connect several wires. According to the installation method of the outer shell 2, the plastic terminal body 1 is changed into a shape that is convenient for installing the outer shell 2, and openings for connecting wires are provided at both ends of the plastic terminal. The way in which the outer shell 2 covers the plastic terminal body 1 ensures that it will not directly contact the outside world, avoiding gaps after damage, and the structure of the outer shell 2 is simple, and the cost is lower than directly replacing the plastic terminal body 1.
[0031] Further, such as Figure 1-3As shown, the first embodiment of the fixing assembly of the present invention is that the fixing assembly includes a latch 4 fixedly connected to the raised portion 3 of the upper shell 201, a spring 5 fixedly connected to the raised portion 3 of the lower shell 202, and a clamping block 6 fixedly connected to one end of the spring 5. A square boss 7 is provided on the raised portion 3 of the lower shell 202, and a plug-in cavity 8 is opened on the square boss 7. The plug-in cavity 8 is in communication with the outside, and the clamping block 6 and the spring 5 are both located in the plug-in cavity 8. An arc-shaped boss 40 is provided on one end of the latch 4. The shape of the arc-shaped boss 40 is similar to that of the clamping block 6, both of which are arc-shaped. The purpose is to enable the two to pass over each other's positions when they are squeezed against each other. , there will be no situation of being stuck and blocked, the clamping block 6 is in active contact with the arc-shaped boss 40. When in use, the upper shell 201 and the lower shell 202 are positioned correspondingly and then combined. During this process, the pin 4 on the upper shell 201 will gradually be inserted into the plug-in cavity 8, and in the process of the pin 4 moving, the arc-shaped boss 40 on the pin 4 will continuously squeeze the clamping block 6, and the clamping block 6 will continuously squeeze the elasticity. After the arc-shaped boss 40 passes over the clamping block 6, the clamping block 6 will squeeze the arc-shaped protrusion, and finally the upper shell 201 will be clamped and fixed on the lower shell 202. In order to ensure the stability of the clamping, multiple such structures can be set.
[0032] like Figure 4-5 As shown, the second embodiment of the fixing assembly of the present invention is that the fixing assembly includes a bolt 9, which is movably connected to the raised portion 3 of the upper shell 201 and the raised portion 3 of the lower shell 202. The bolt 9 is used to fix the upper shell 201 and the lower shell 202, and for the sake of stability, a plurality of bolts 9 can be provided. When in use, the upper shell 201 and the lower shell 202 are positioned correspondingly and then combined. After the upper shell 201 and the lower shell 202 are docked, the bolt 9 is used to be threadedly connected to the upper shell 201 and the lower shell 202 respectively. At this time, the upper shell 201 and the lower shell 202 are fixed together. Compared with the first embodiment of the fixing assembly, the fixing structure of this embodiment is more stable.
[0033] like Figure 6-7As shown, the third embodiment of the fixing assembly of the present invention is that the fixing assembly includes a threaded portion 10 provided on both ends of the upper shell 201 and a threaded portion 2 11 provided on both ends of the lower shell 202. The threaded portion 10 and the threaded portion 2 11 are connected by a threaded cap 12. A long protrusion 13 is provided on the raised portion 3 of the upper shell 201, and a long groove 14 corresponding to the long protrusion 13 is provided on the raised portion 3 of the lower shell 202. The long protrusion 13 is movably connected with the long groove 14. In use, the upper shell 201 and the lower shell 202 are still positioned. After the corresponding parts are matched and combined, the long protrusion will be stuck in the long groove 14. At this time, the threaded part 10 and the threaded part 2 11 are in contact and correspondence. At this time, the threaded part 10 and the threaded part 2 11 form a circular structure. Then use the threaded cap 12 to screw on the threaded part 10 and the threaded part 2 11. Finally, the threaded part 10 and the threaded part 2 11 are combined together and fixed, thereby fixing the upper shell 201 and the lower shell 202. Compared with the second embodiment of the fixing component, the fixing structure of this embodiment is faster and more stable.
[0034] Furthermore, a through slot 15 is provided on the plastic terminal body 1, the purpose of which is to allow the pressing piece 104 to extend out and facilitate pressing the pressing piece 104. The connecting assembly includes a plastic shell 101 with a hollow structure, two elastic pieces 102 fixedly connected to the inside of the plastic shell 101 and symmetrically, an extrusion piece 103 in contact with the elastic piece 102, and a pressing piece 104 slidably connected to the extrusion piece 103, and one end of the pressing piece 104 extends to the outside of the plastic shell 101, the two elastic pieces 102 are in contact with each other, and the two elastic pieces 102 are made of metal or other conductive materials, and the conductive ends of the two wires are respectively inserted from both ends of the plastic shell 101, and during the insertion process, the pressing piece 104 is pressed and moves downward, and during the downward movement of the pressing piece 104, one end of the pressing piece 104 extends to the outside of the plastic shell 101, and the two elastic pieces 102 are in contact with each other, and the two elastic pieces 102 are made of metal or other conductive materials. The conductive ends of the two wires are respectively inserted from the two ends of the plastic shell 101, and during the insertion process, the pressing piece 104 is pressed and moves downward. The end will continuously squeeze the elastic member 102. Since the extrusion member 103 is fixed on the inside of the plastic shell 101, a certain space gap is generated between the squeezed end of the elastic member 102 and the extrusion member 103. At this time, the conductive end of the wire will move directly to the space gap after being inserted from one end of the plastic shell 101. Then the pressing member 104 is released, and the elastic member 102 releases its elastic force and squeezes the pressing member 104 back. Since there is a conductive end of the wire between the elastic member 102 and the extrusion member 103, the elastic member 102 will be blocked by the conductive end of the wire after releasing its elastic force. Under the joint clamping action of the elastic member 102 and the extrusion member 103, the conductive end of the wire is clamped and fixed at the position between the elastic member 102 and the extrusion member 103. After the two wires are energized, the two elastic members 102 act as conductors.
[0035] like Figures 1-10As shown, the principle of the plastic terminal with insulation protection provided by this embodiment is as follows: when in use, the conductive ends of the two wires are respectively inserted from the two ends of the plastic shell 101, and during the insertion process, the pressing piece 104 is pressed and the pressing piece 104 is moved downward. During the downward movement of the pressing piece 104, one end of the pressing piece 104 will continuously squeeze the elastic piece 102. Because the extrusion piece 103 is fixed on the inside of the plastic shell 101, a certain space gap is generated between the extruded end of the elastic piece 102 and the extrusion piece 103. At this time, the conductive end of the wire will move directly to the space gap after being inserted from one end of the plastic shell 101. Then the pressing piece 104 is released, and the elastic piece 102 releases its elastic force and squeezes the pressing piece 104 back. Because there is a conductive end of the wire between the elastic piece 102 and the extrusion piece 103, the elastic piece 102 will be blocked by the conductive end of the wire after releasing its elastic force. Under the joint clamping action of the parts 103, the conductive end of the wire is clamped and fixed at the position between the elastic part 102 and the extrusion part 103, and the two conductive ends of the wires that need to be electrically connected are fixed using this method. Then the upper shell 201 and the lower shell 202 are respectively put on the outer surface of the plastic shell 101, and the protrusion 3 on the upper shell 201 contacts the protrusion 3 on the lower shell 202, and the positions correspond. Then use the fixing component to fix the upper shell 201 and the lower shell 202. After the fixed connection, the upper shell 201 and the lower shell 202 are now fixedly connected to the outer surface of the plastic shell 101. When the plastic terminal body 1 is in use, the outer shell 2 will protect the plastic terminal body 1. After the outer shell 2 is damaged, the upper shell 201 or the lower shell 202 can be replaced by releasing the fixing component to the upper shell 201 and the lower shell 202.
