Detailed ways

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

As shown in Figure 2 and Figure 3, the utility model provides a compressor wiring device.

Specifically, the compressor wiring device is disposed on the terminal cover 10 . The terminal cover 10 is welded on the end cover of the compressor by resistance welding. The compressor wiring device includes a first terminal 21 , a second terminal 22 and a third terminal 23 . The first terminal 21 is penetrated through the terminal cover 10 , the second terminal 22 is penetrated through the terminal cover 10 , and the third terminal 23 is penetrated through the terminal cover 10 . Wherein, the length of the first terminal 21 extending into the inside of the terminal cover 10 is at least the same as the length of the second terminal 22 extending into the inside of the terminal cover 10 and the length of the third terminal 23 extending into the inside of the terminal cover 10 One of them is of unequal length.

Since at least two terminal posts extend into the inner side of the terminal cover 10, there is a difference in length, so on the one hand, it can prevent the wrong wiring of the power supply, and on the other hand, it also increases the safe creepage distance between the various parts on the terminal post. . Therefore, the compressor wiring device of the utility model is safe and reliable.

As shown in Figure 2, the length of the second terminal 22 extending into the inside of the terminal cover 10 is the same as the length of the third terminal 23 extending into the inside of the terminal cover 10, and the first terminal 21 extends into the terminal cover. The length of the inner side of the terminal 10 is longer than the length of the second terminal 22 protruding into the inner side of the terminal cover 10 . Of course, it is also possible that the length of the first terminal 21 protruding into the terminal cover 10 is shorter than the length of the second terminal 22 protruding into the terminal cover 10 . All of the above can be determined according to the needs of the actual space. That is to say, among the three terminals, two of them have the same length extending into the terminal cover 10 , and the other terminal has a longer length extending into the terminal cover 10 . It can prevent the power wiring from being wrongly connected, and also increases the safe creepage distance between the various parts on the terminal.

The length of the first terminal 21 extending into the inside of the terminal cover 10 is greater than the length of the second terminal 22 extending into the inside of the terminal cover 10, and the length of the first terminal 21 extending into the inside of the terminal cover 10 is the same as the length of the second terminal 22 extending into the inside of the terminal cover 10. The difference between the lengths of the two terminals 22 protruding into the interior of the terminal cover 10 is greater than 0 mm and less than or equal to 10 mm. Preferably, the length of the first terminal 21 protruding into the terminal cover 10 is 5 mm longer than the length of the second terminal 22 protruding into the terminal cover 10 . Considering the three considerations of saving materials, making full use of space and ensuring the safe creepage distance, the length of the two terminals extending into the inside of the terminal cover 10 is the same length, and the length of the other terminal extending into the inside of the terminal cover 10 is less than Longer, 5mm longer.

In another embodiment, as shown in FIG. 3 , the length of the first terminal 21 protruding into the inner side of the terminal cover 10 , the length of the second terminal 22 protruding into the inner side of the terminal cover 10 and the length of the third terminal 23 The lengths extending into the inside of the terminal cover 10 are not equal.

Three binding posts stretch into the length of that part of binding post cover inboard, and can decide respective suitable length according to the needs of actual space. It prevents the wrong wiring of the power supply, and also increases the safe creepage distance between the various parts on the terminal.

Because the size of the terminal does not have much difference in the horizontal direction, this will lead to insufficient space in the horizontal direction of the terminal in some special occasions, and it needs to be improved in the direction of the terminal up and down. space for wiring. Solve the problem of safety distance and improve the safety and reliability level of the product. At the same time, after the lengths of the three terminals are different, it is easier to identify and connect them, so that the main, auxiliary and common phases have obvious characteristics.

Preferably, the insertion piece 30 is welded to the first terminal 21 , the second terminal 22 and the third terminal 23 . The connection method is simple and reliable.

In some special cases, such as the need to use a relatively large protector, or the lead wire assembly of the motor also needs to be changed due to the change of the production process, so that the safety distance between the original wiring components is not enough.

Preferably, the first terminal post 21 , the second terminal post 22 and the third terminal post 23 are circumferentially distributed around the axis of the terminal post cover 10 . That is to say, the first terminal 21 , the second terminal 22 and the third terminal 23 are distributed in a triangle on the terminal cover 10 . This design makes reasonable use of the space.

Specifically, as shown in FIG. 4 , three motor lead-out wires are connected to the terminal post, and the three motor lead-out wires include two first motor lead-out wires 60 a connected to the insert 30 wrapped by the motor lead-out wire insert terminal 40 , It also includes a second motor lead wire 60b connected to the terminal through the metal shell 50 of the protector. The lengths of the three binding posts are not exactly the same, so the safe creepage distance between the blade terminal 40 of the motor lead wire 60a and the metal shell 50 of the protector is ensured, and the distance between the motor lead wire 60a and the metal shell 50 of the protector is also ensured. safe creepage distance.
