At the same time, contrary to the first matching insertion, the insertion groove 13 receives the insertion of the insertion protrusion 23, which belongs to the first cross-verification, and the insertion method is: inserting from left to right, contrary to the above insertion method.

[0037] As Figure 3 shown, inside the insertion groove 13, there are first insertion terminals 15, and the first insertion terminals 15 are connected to the second power cable 14. The number of the first insertion terminals 15 is also two, and they are arranged left and right; the first insertion terminals 15 are inserted into the first receiving terminals 25 inside as the third matching insertion. At the same time, contrary to the second matching insertion, the first insertion terminals 15 are inserted into the first receiving terminals 25 inside, which belongs to the second cross-verification. The first insertion terminals 15 in the male socket 1 are inserted into the first receiving terminals 25 in the female socket 2, and the insertion method is: inserting from right to left, contrary to the above insertion method.

[0038] The first power cable 24 and the second power cable 14 are respectively connected to the positive and negative poles of the power supply to transmit a relatively large current to drive the motor. In this embodiment, the male socket 1 and the female socket 2 are plugged once, and there are three matches and three verifications inside, and two cross-verifications, thus preventing plugging errors.

The push switch 26 is T-shaped and integrally formed with the second housing 11. The lower part of the push switch 26 is a support part 29, one end is a pressing part 27, and the other end is a first hook 28. The first hook 28 is inserted into one side of the clamping protrusion 16 to connect the male seat 1 and the female seat 2. Further, a number of transverse protruding stripes are provided on the pressing part 27.

[0041] In order to strengthen the sealing performance after insertion, a sealing groove 17 is provided on the insertion part 12; a sealing ring 18 is installed in the sealing groove 17, and the sealing is achieved by the extrusion of the accommodating part 22 on the sealing ring 18.

[0042] In order to improve the installation convenience of the connector assembly, an installation panel 215 is further provided on the first housing 21. A number of installation through holes 216 for fixing the installation panel 215 are provided around the installation panel 215; the bolt fixes the installation panel 215 through the installation through holes 216.

[0043] As shown Figure 2 in the figure, a second insertion terminal 32 connected to the first signal cable 31 is installed in the accommodating part 22; as shown Figure 3 in the figure, a receiving groove 41 is provided inside the insertion part 12, and a second receiving terminal 43 connected to the second signal cable 42 is installed inside the receiving groove 41; the second insertion terminal 32 is inserted into the second receiving terminal 43 to achieve signal connection.

[0045] As shown Figure 6 in the figure, the first insertion terminal 15 includes a first insertion cylinder 151, a first installation part 152 and a first cylinder part 153. The first cylinder part 153 is fixedly connected to the second power cable 14. Specifically, a first groove 155 is provided inside the first cylinder part 153. The second power cable 14 is inserted into the first groove 155, and the first cylinder part 153 is riveted to fix the second power cable 14; an observation hole 156 is further provided on the first cylinder part 153, and the observation hole 156 is used to observe whether the second power cable 14 is inserted in place.

[0046] The insertion groove 13 is provided with a first placement portion 51 for placing the first insertion terminal 15; the first placement portion 51 includes a first through hole 511 for accommodating the first insertion cylinder 151 and a second through hole 512 for accommodating the first mounting portion 152. A second catch 513 for fixing the first mounting portion 152 is provided at the end of the second through hole 512; the diameter of the first through hole 511 is smaller than that of the second through hole 512. The first insertion cylinder 151 can pass through the first through hole 511, but the first through hole 511 catches one end of the first mounting portion 152, and the second catch 513 also catches the other end of the first mounting portion 152, thereby fixing the first insertion terminal 15.

[0047] As Figure 6 and Figure 11 shown, a plastic cap 154 is sleeved on the end of the first insertion cylinder 151; specifically, a placement groove 157 is provided at the end of the first insertion cylinder 151, and a fourth catch 158 matching the placement groove 157 is provided inside the plastic cap 154. The fourth catch 158 is clamped inside the placement groove 157, thereby fixedly connecting the plastic cap 154 and the first insertion cylinder 151. Symmetric arc-shaped through holes 159 are also provided at the end of the plastic cap 154, and the arc-shaped through holes 159 penetrate the plastic cap 154, making the plastic cap 154 easy to deform and compress, thereby reducing the volume.

[0048] As Figure 4 shown, the insertion protrusion 23 is provided with a second placement portion 71 for placing the first receiving terminal 25; the first receiving terminal 25 is divided into three parts. The first receiving terminal 25 includes a contact member 61, a base body 62, and a connecting member 63; the contact member 61, the base body 62, and the connecting member 63 are connected in sequence and integrally bent by a press; the connecting member 63 is fixedly connected to the first power cable 24; the first power cable 24 is placed inside the connecting member 63, and the two are riveted together by a press; the contact member 61 is provided with a plurality of first elastic pieces 64; one end of the first elastic piece 64 is connected to the contact member 61, and the other end is connected to the base body 62. The first elastic piece 64 forms an elastic contact area 65 by inwardly concave inner walls and contacts the first insertion cylinder 151, thereby making a connection and achieving multi-point connection to meet large-current transmission.

[0049] The contact member 61 and the base body 62 are further provided with a first cylindrical groove 66. A first clamping ring 67 is sleeved on the first cylindrical groove 66. The first clamping ring 67 is bent and formed to be attached to the surface of the first cylindrical groove 66. One end of the outer surface of the first clamping ring 67 is evenly provided with first clamping members 68 for clamping inside the second placement portion 71, and the other end is evenly provided with second elastic pieces 69 that contact the first elastic piece 64 inwardly; the first clamping members 68 gradually increase from left to right; thus contacting the second placement portion 71; the second elastic pieces 69 apply a force to the first elastic piece 64, thereby increasing the elasticity of the first elastic piece 64 and causing the first elastic piece 64 to remain recessed inwardly.

[0050] Further, a second clamping ring 73 is sleeved on the first clamping ring 67. The second clamping ring 73 is evenly provided with inner protrusions 74 that squeeze the second elastic piece 69 inwardly; the inner protrusions 74 squeeze the second elastic piece 69 inwardly, causing the second elastic piece 69 to apply a force to the first elastic piece 64, such that the first elastic piece 64 has a larger elastic coefficient and also has greater elasticity.

[0051] The second insertion terminal 32 has the same structure as the first insertion terminal 15, except for the different diameters. The diameter of the first insertion terminal 15 is much larger than that of the second insertion terminal 32, so that one transmits electricity and the other transmits signals; the second insertion terminal 32 includes a second insertion cylinder 321, a second installation portion 322, and a second cylinder portion 323. The second cylinder portion 323 is fixedly connected to the first signal cable 31; specifically, a second groove 325 is provided inside the second cylinder portion 323. The first signal cable 31 is inserted into the second groove 325, and the second cylinder portion 323 is riveted to fix the first signal cable 31; the second cylinder portion 323 is further provided with an observation hole 156 for observing whether the first signal cable 31 is inserted in place.

[0052] The accommodation portion 22 is provided with a third placement portion 81 for placing the second insertion terminal 32; the third placement portion 81 includes a third through hole 82 for accommodating the second insertion cylinder 321 and a fourth through hole 83 for accommodating the second installation portion 322.

The diameter of the third through hole 82 is smaller than that of the fourth through hole 83. The second insertion cylinder 321 can pass through the third through hole 82, but the third through hole 82 clamps one end of the second installation portion 322, and the third clamping hook 84 also clamps the other end of the second installation portion 322, thereby fixing the second insertion terminal 32.

[0053] As Figure 7As shown, the second receiving terminal 43 includes a harpoon terminal 431 and a connecting portion 432. The harpoon terminal 431 is provided with a U-shaped opening 433 for inserting into the second insertion cylinder 321.
