Specifically, the first anti-reverse connection member 3 and the second anti-reverse connection member 4 are in a symmetrical structure, wherein the first anti-reverse connection member 3 is a guide sleeve 7 with a thread at one end, and the second anti-reverse connection member 4 is a guide post 8 with a thread at one end. According to different application scenes, the utility model discloses a first prevent that connecting piece 3 and second prevent that connecting piece 4 figure can be the same. Further, the first anti-reverse connection piece 3 and the second anti-reverse connection piece 4 are designed into symmetrical structures. Thus, when the first connection end 1 and the second connection end 2 are correctly installed, the first anti-reverse connection member 3 is opposite to the second anti-reverse connection member 4. Because the first anti-reverse connecting piece 3 is the guide sleeve 7 and the second anti-reverse connecting piece 4 is the guide column 8, the guide column 8 can be inserted in the guide sleeve 7 at the moment, so that the first connecting end 1 and the second connecting end 2 can be correctly inserted together. In contrast, when the first connection end 1 and the second connection end 2 are attempted to be installed in a wrong manner (i.e., "reversed"), the first reverse connection preventing member 3 and the second reverse connection preventing member 4 may contact or abut against the fixing bolt, so that the first connection end 1 and the second connection end 2 cannot be plugged together. In this case, the first connection end 1 and the second connection 2 can only be plugged together by means of a direction adjustment (i.e. an adjustment of the installation direction or the plugging direction). It can be seen that the utility model discloses a prevent slow-witted design and can prevent effectively that the link from reversely inserting to play the effective protection to the circuit.

The first connecting end 1 and the second connecting end 2 have the same structure. The connecting terminal 5 used in the present application may be the connecting terminal 5 used in a common heavy-duty connector in the market, and therefore, the description is not made herein too much, and the terminal fixing plate 6 may play a role of fixing the connecting terminal 5, and also play a role of fixedly connecting the connecting terminal 5 to other devices.

Fig. 6 shows the structure of a first anti-reverse connector 3 and a second anti-reverse connector 4, wherein the first anti-reverse connector 3 and the second anti-reverse connector 4 have the same structure. The first anti-reverse connecting piece 3 is a guide pin with a thread at one end, when the first connecting end 1 and the second connecting end 2 are correctly installed, the first anti-reverse connecting piece 3 and the second anti-reverse connecting piece 4 are in a symmetrical inverted image, so that the first anti-reverse connecting piece 3 and the second anti-reverse connecting piece 4 cannot touch each other when the first connecting end 1 and the second connecting end 2 are installed, when the first connecting end 1 and the second connecting end 2 are installed wrongly, as shown in figure 7, the first anti-reverse connecting piece 3 and the second anti-reverse connecting piece 4 are in a symmetrical structure, so that the first anti-reverse connecting piece 3 and the second anti-reverse connecting piece 4 can touch each other when the first connecting end 1 and the second connecting end 2 are installed, the first connecting end 1 and the second connecting end 2 cannot be connected in an inserting mode only by reversing, the connecting terminals can be effectively prevented from being inserted together by the design, and M series of guide pins can be selected, preferably, the guide pin M3 is selected for the 2P heavy-duty connector, the guide pin M6 is selected for the 3P heavy-duty connector, the guide pin with threads is used for facilitating installation, the guide pin can also be used as a fixing screw, the multi-purpose function of the pin is achieved, and other anti-reverse connecting pieces such as a spring guide pin, a guide plate and the like can be adopted according to different requirements.

The second type of first and second anti-links 3 and 4 is structurally similar to 2P. As shown in fig. 5, the number of connection terminals of this connector is increased by one with respect to the 2P structure, and the first anti-reverse connector 3 and the second anti-reverse connector 4 have a symmetrical structure. In one embodiment, the first anti-link 3 is a threaded boot 7 and the second anti-link 4 is a threaded post 8. The number of the first and second anti-links 3 and 4 may be the same. When the first connecting end 1 and the second connecting end 2 are correctly installed, the first anti-reverse connecting piece 3 is opposite to the second anti-reverse connecting piece 4.
