[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The utility model provides a plastic shell quick plug for quick plug-in connection, comprising a shell 1, an aluminum row 2, a fixing plate 3 and a flexible composite contact finger 4;

[0028] The outer part of the housing 1 is fixedly mounted with a fixing plate 3; the inner part of the housing 1 is fixedly mounted with an aluminum bar 2; the aluminum bar 2 includes an integrally formed U-shaped portion 2.1 and a flat portion 2.2; the U-shaped portion 2.1 is provided with a U-shaped groove 2.3, and the left and right sides of the U-shaped groove 2.3 are provided with contact finger grooves 2.4, and the flexible composite contact fingers 4 are assembled in the contact finger grooves 2.4; the lower part of the U-shaped portion 2.1 is the flat portion 2.2. To facilitate the assembly of the flexible composite contact fingers 4, the top of the U-shaped groove 2.3 is provided with a second oblique insertion opening 2.6. The flat portion 2.2 is provided with a round hole 2.7.

[0029] The utility model provides a plastic shell quick plug for quick plug-in connection, which mainly includes four parts: a shell 1, an aluminum bar 2, a fixing plate 3 and a flexible composite contact finger 4. The shell 1 is made of insulating engineering plastics with excellent strength and toughness. When in use, the aluminum bar 2 assembled with the flexible composite contact finger 4 is inserted into the shell 1 and fixed. The aluminum bar 2 is drawn from aluminum profiles, and then surface-plated after cutting, which is low-cost. The surface is electroplated to reduce contact resistance, which can connect the flexible composite contact finger 4 with the external conductive part to form a closed loop. The fixing plate 3 is made of aluminum bar, which is used for good contact connection between the entire device and other conductive bars. The quick plug allows a certain installation error, thereby ensuring good contact force and sufficient conductive contact force.

[0030] To facilitate the clamping assembly of the shell 1 and the aluminum bar 2, as a specific implementation structure, the shell 1 includes a support base 1.1, an upper shell 1.2 and a lower shell 1.3; the upper shell 1.2 is arranged above the support base 1.1, and the upper shell 1.2 has an upper cavity 1.4 matching the U-shaped portion 2.1; the lower shell 1.3 is arranged below the support base 1.1, and the lower shell 1.3 has a lower cavity 1.5 matching the flat portion 2.2; the lower cavity 1.5 is connected to the upper cavity 1.4.

[0031] The inner wall of the lower shell 1.3 is provided with a female buckle 1.6, and the outer wall of the flat portion 2.2 of the aluminum bar 2 is provided with a male buckle 2.5 that cooperates with the female buckle 1.6. Therefore, when the aluminum bar 2 is inserted from the upper cavity 1.4 of the shell 1, when the male buckle 2.5 of the flat portion 2.2 of the aluminum bar 2 contacts and fastens with the female buckle 1.6 of the lower shell 1.3, the aluminum bar 2 is assembled in place, and at the same time, the male buckle 2.5 and the female buckle 1.6 cooperate to achieve the fixation between the aluminum bar 2 and the shell 1, avoid mutual movement, and the assembly process is simple.

[0032] To enhance the strength of the structure, external ribs 1.7 are provided on the outside of the upper shell 1.2, and internal ribs 1.8 are provided in the inner cavity of the upper shell 1.2. Reinforcing ribs 1.10 are provided on the outer wall of the lower shell 1.3; an outer baffle 1.11 is provided on the outside of the lower shell 1.3. To facilitate the insertion of the aluminum bar 2, a first oblique insertion opening 1.9 is provided at the insertion opening position of the upper cavity 1.4 of the upper shell 1.2. The first oblique insertion opening 1.9 can correct the aluminum bar 2 that is not aligned, so that the aluminum bar 2 can be easily introduced.

[0033] To facilitate the assembly of the fixing plate 3, a fixing plate slot 1.12 for mounting the fixing plate 3 is provided on the outer side of the support seat 1.1. The fixing plate 3 is provided with a through hole 3.1, through which the fixing plate 3 is connected and fixed to an external conductive connector by bolts.

[0034] The actual use method of the utility model is as follows: first, the flexible composite contact finger 4 is assembled into the contact finger groove 2.4 of the aluminum bar 2, and then the aluminum bar 2 assembled with the flexible composite contact finger 4 is pushed into the shell 1, and the male buckle 2.5 of the aluminum bar 2 and the female buckle 1.6 of the shell 1 cooperate with each other to fix the aluminum bar 2 and the shell 1 to each other.

[0035] The quick plug can be installed at the power receiving part, and the conductive bar at the power supply part cooperates with other switch mechanisms to form a closed and open circuit. The conductive bar is inserted into the flexible composite contact finger 4 to realize the electrical connection path between the conductive bar and the quick plug. The quick plug allows a certain installation error, thereby ensuring good contact force and sufficient conductive contact force.

[0036] The utility model provides a plastic shell quick plug for quick plug-in connection, which has the following advantages:

[0037] 1) Reduce costs and weight while ensuring good electrical conductivity;

[0038] 2) Its structure is relatively simple, with many contact points, good current carrying capacity and low insertion and extraction force;

[0039] 3) Chamfer the aluminum bar of the quick connector to facilitate insertion.

[0040] 4) Easy to install, just assemble the aluminum bar and the flexible composite contact finger and put them into the shell;

[0041] 5) The structure is tight and can withstand long-term vibration in working state;

[0042] 6) Long service life, sliding can reach more than 10,000 times;

[0043] 7) The design of the plastic shell increases the creepage distance, making the use process safer.

[0044] 8) The structure is light, consisting of only four parts, and can be assembled quickly; it is firm and reliable, the flexible composite contact finger and the aluminum bar are fixed in position by the shell, the aluminum bar is inserted into the shell, and the female buckle on the shell and the male buckle on the aluminum bar are used for positioning and matching, so that the plastic shell and the aluminum bar are fixed to each other.

[0045] The above is only a preferred embodiment of the present invention.
