TABLE 1 Effect of different torques on the connection
Figure BDA0003390133600000061
As can be seen from table 1 above, when the torque value of the screw structure and the screw is less than 0.1N · m, the charging terminal 2 and the transition terminal 1 are loosened after the vibration test, and when the torque value is greater than 17N · m, the torque applied to the transition terminal 1 and the charging terminal 2 is too large due to the excessive torque, so that the transition terminal 1 is deformed by a large pressure, and the basic function of the charging stand cannot be realized. Therefore, the inventors determined the torque range of screwing the screw structure with the screw member to be 0.1N · m to 17N · m.
Further, as shown in fig. 5, the transition terminal 1 may adopt a straight plate structure, a boss 14 is disposed at a first end of the transition terminal 1, and an end surface of the screw abuts against the boss 14. The thickness size of boss 14 department is greater than the thickness size with cable 3 junction, and the thickness difference makes things convenient for transition terminal 1 and the connection of screw joint spare, makes things convenient for cable 3 to be connected simultaneously. The transition terminal 1 may be of unitary molded construction.
Further, according to the operating condition demand, transition terminal 1 can also adopt the bent plate structure, is the contained angle setting between the first end of bent plate structure and the second end of bent plate structure, and the angle scope of contained angle is 0 ~ 360. The bent plate structure can meet the requirement of the outgoing angle of the cable 3 to a certain extent.
Preferably, the second end of the transition terminal 1 is connected to the cable 3 by one of crimping, plugging, clamping, bolting, riveting, welding, bundling or locking.
In a first possible technical solution, a crimping structure may be adopted, such as providing crimping surfaces on the transition terminal 1 and the charging terminal 2, and the charging terminal 2 is fixedly connected with the transition terminal 1 by means of crimping.
In a second possible technical solution, a plug-in structure may be adopted, for example, a plug is disposed on the end surface of the transition terminal 1, a slot is disposed on the charging terminal 2, and the plug is fixedly connected after being inserted into the slot.
In a third feasible technical scheme, a clamping structure can be adopted, for example, a buckle is arranged on the surface to be spliced of the transition terminal 1, and a clamping groove is arranged on the charging terminal 2 to complete clamping.
In the fourth feasible technical scheme, a bolt connection structure can be adopted, an external thread is arranged on the transition terminal 1, and an internal thread is arranged on the charging terminal 2, so that the bolt connection is completed.
In a fifth feasible technical scheme, a riveting structure can be adopted, the riveting structure comprises a rivet and a fixing hole, the fixing hole is formed in the transition terminal 1, and the rivet is arranged on the charging terminal 2 to complete riveting.
In a sixth possible solution, a welded structure may be used.
Specifically, the second end of the transition terminal 1 and the cable 3 are connected together by a friction welding method, an ultrasonic welding method, an arc welding method, a laser welding method or an electric resistance welding method.
The friction welding method is a method of welding by plastically deforming a workpiece under pressure using heat generated by friction of a contact surface of the workpiece as a heat source.
The ultrasonic welding method is a method in which high-frequency vibration waves are transmitted to the surfaces of two objects to be welded, and the surfaces of the two objects are rubbed against each other under pressure to form fusion between the molecular layers.
The arc welding method is a method of connecting metals by converting electric energy into thermal energy and mechanical energy required for welding using an electric arc as a heat source and utilizing a physical phenomenon of air discharge, and the main methods include shielded metal arc welding, submerged arc welding, gas shielded welding, and the like.
The laser welding method is an efficient and precise welding method using a laser beam with high energy density as a heat source.

In a seventh possible technical solution, a bundling structure may be adopted, the bundling structure including a bundling piece, grooves are provided on surfaces of the transition terminal 1 and the charging terminal 2, and the transition terminal 1 and the charging terminal 2 are bundled together at the groove positions using the bundling piece. The strapping includes a strap, a pipe clamp, a hook lock, etc.
In an eighth possible technical solution, a locking structure may be adopted, where the locking structure includes locking pieces, and the locking pieces are respectively disposed on the surfaces of the transition terminal 1 and the charging terminal 2 to complete locking connection.
Further, the transition terminal 1 is made of tellurium copper alloy, wherein the content of tellurium is 0.1% -5%.
That is to say, when the material of the transition terminal 1 is tellurium copper alloy, the transition terminal 1 has good conductivity and easy machinability, the electrical property is ensured, the processability can be improved, and meanwhile, the elasticity of the tellurium copper alloy is also excellent. Preferably, the tellurium content in the tellurium-copper alloy is 0.2% -1.2%.
The inventor selects 10 transition terminals 1 with the same shape for testing, and each transition terminal 1 is tellurium-copper alloy, wherein the content of tellurium accounts for 0.05%, 0.1%, 0.2%, 1%, 1.2%, 1.8%, 3%, 5%, 6% and 7% respectively. As shown in Table 2, in the present example, the conductivity of the tellurium copper alloy is greater than 99% as the ideal value.
Table 2: influence of tellurium copper alloys with different tellurium contents on the conductivity.
Tellurium content 0.05% 0.1% 0.2% 1% 1.2% 1.8% 3% 5% 6% 7%
Electrical conductivity of 98.6% 99.1% 99.3% 99.6% 99.8% 99.5% 99.3% 99.1% 98.9% 98.7%
As is clear from Table 2, when the content ratio of tellurium is less than 0.1% or more than 5%, the conductivity is remarkably decreased and the desired value cannot be satisfied. When the content of tellurium accounts for more than or equal to 0.2 percent and less than or equal to 1.2 percent, the conductivity is the best, so the inventor selects tellurium copper alloy with 0.1 to 5 percent of tellurium content. Under the most ideal condition, 0.2-1.2% tellurium-copper alloy is selected.
In a preferred embodiment, the transition terminal 1 is provided with a plating.
The plating layer is used for improving corrosion resistance and conductivity, increasing the use times and prolonging the service life of the transition terminal 1 better.
The plating layer can adopt methods such as electroplating, chemical plating, magnetron sputtering or vacuum plating.
The electroplating method is a process of plating a thin layer of other metals or alloys on the surface of some metals by utilizing the electrolysis principle.
The chemical plating method is a deposition process for generating metal through controllable oxidation-reduction reaction under the catalytic action of the metal.
The magnetron sputtering method is characterized in that electrons spirally run near the surface of a target by utilizing the interaction of a magnetic field and an electric field, so that the probability of generating ions by the electrons colliding with argon is increased. The generated ions collide with the target surface under the action of the electric field so as to sputter the target material.
The vacuum plating method is to deposit various metal and non-metal films on the surface of the plastic part by distillation or sputtering under vacuum condition.
The coating is made of one or more of gold, silver, nickel, tin, zinc, tin-lead alloy, silver-antimony alloy, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy.
Copper or aluminum is used as an active metal and can be subjected to oxidation reaction with oxygen and water in the using process, so that one or more inactive metals are required to be used as a plating layer, and the service life of the transition terminal 1 is prolonged. In addition, better wear-resistant metal is needed to be used as a plating layer, so that the service life of the contact can be greatly prolonged. The transition terminal 1 needs to have good conductivity, and the conductivity and stability of the metal are superior to those of copper or copper alloy and aluminum or aluminum alloy, so that the transition terminal 1 can obtain better electrical performance and longer service life.
In order to demonstrate the influence of different coating materials on the overall performance of the transition terminal 1, the inventor uses the same specification and material, and adopts transition terminal 1 samples of different coating materials to carry out a series of plugging times and corrosion resistance time tests. The results of the experiment are shown in table 3 below.
The following table 3 shows the plugging times that the transition terminals 1 are respectively fixed on a laboratory bench, the transition terminals 1 are plugged in and unplugged in a simulation mode by a mechanical device, and the situation that the surface plating layer of the transition terminals 1 is damaged is observed when plugging is performed for 100 times, the surface plating layer of the terminals is scratched, the material of the terminals is exposed, the experiment is stopped, and the plugging times at that time are recorded. The plugging times are less than 8000 times, which is not qualified.
The corrosion resistance time test in table 3 below is to place the transition terminal 1 in a salt spray test box, spray salt spray to each position of the transition terminal 1, take out and clean every 20 hours to observe the surface corrosion condition, i.e. a cycle, stop the test until the corrosion area of the surface of the transition terminal 1 is greater than 10% of the total area, and record the cycle number at that time. In this example, the number of cycles less than 80 was considered to be unacceptable.
Table 3: influence of different coating materials on insertion and extraction times and corrosion resistance of transition terminal
Figure BDA0003390133600000091
From the above table, when the selected plating layer is made of gold, silver-antimony alloy, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy, the experimental result exceeds the standard value more and the performance is more stable. When the material of the plating layer is nickel, tin-lead alloy and zinc, the experimental result can meet the requirement, so that the inventor selects the material of the plating layer to be one or a combination of more of gold, silver, nickel, tin-lead alloy, zinc, silver-antimony alloy, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy.
