[0042] like Figures 1 to 3 As shown, a connector assembly 10 of an embodiment includes a plug connector 100 and a socket connector 300. The plug connector 100 and the socket connector 300 are plug-in connected, so that the plug connector 100 and the socket connector 300 are electrically connected, and the circuit conduction on both sides of the connector assembly 10 is realized. In one embodiment, the plug connector 100 includes a plug body 110, a power contact 120 and a signal contact 130.

The signal contact 130 is used to be pluggable connected to the signal plug kit 330 of the socket connector 300, so as to be electrically connected to the signal plug kit 330, so that the signal contact 130 is pluggable connected to the signal plug kit 330.

[0044] like Figure 2 and Figure 4 As shown, further, the socket connector 300 includes a socket body 310, a power plug kit 320 and a signal plug kit 330. The socket body 310 is provided with a plugging boss 312, and the plugging boss 312 is plugged into the plug slot 112, so that the plug slot 112 and the socket connector 300 are plugged and unplugged. The plugging boss 312 is provided with a first receiving groove 312a and a second receiving groove 312b. The power plug kit 320 is located in the first receiving groove 312a and connected to the plugging boss 312, and the power plug kit 320 is used to be plugged and unplugged with the power contact 120 to be electrically connected with the power contact 120. The signal plug kit 330 is located in the second receiving groove 312b and connected to the plugging boss 312, and the signal plug kit 330 is used to be plugged and unplugged with the signal contact 130 to be electrically connected with the signal contact 130.

[0045] The above-mentioned plug connector 100, socket connector 300 and connector assembly 10, the plug connector 100 and the socket connector 300 are plug-in connected, that is, the plug boss 312 is plugged into the plug slot 112, the power contact 120 is plugged into the power plug kit 320, and the signal contact 130 is plugged into the signal plug kit 330. Since the plug body 110 is provided with a connected plug slot 112 and an open slot 114, the plug slot 112 is pluggable and connected to the socket connector 300. When debris such as sand or water falls into the plug slot 112, the debris or water can be discharged through the open slot 114, or the user can quickly clean the debris or water through the open slot 114, thereby solving the problem that it is difficult for the user to clean the debris or water in the slot; even if the user does not notice the debris or water and does not perform a cleaning operation, during the plug-in and unplugging process of the plug slot 112 and the socket connector 300, the debris or water is squeezed by the insertion of the socket connector 300 and discharged from the open slot 114, thereby solving the problem of short service life of the equipment.

[0046] like Figure 3As shown, in one embodiment, the opening slot 114 is provided on the side wall of the plug body 110, the plugging slot 112 is provided along the plugging and unplugging direction of the plug body 110 and the socket connector 300, and the opening direction of the opening slot 114 and the opening direction of the plugging slot 112 are at an angle, so that water or debris in the plugging slot 112 can be quickly discharged through the opening slot 114. In this embodiment, the opening direction of the opening slot 114 and the opening direction of the plugging slot 112 form an angle of 90°, that is, the opening direction of the opening slot 114 and the opening direction of the plugging slot 112 are perpendicular to each other. It can be understood that in other embodiments, the opening direction of the opening slot 114 and the opening direction of the plugging slot 112 are not limited to 90°, but can also be other angles.

[0047] like Figure 3 As shown, in one embodiment, the opening groove 114 is adjacent to the bottom of the plug-in groove 112, so that water or debris in the plug-in groove 112 can be quickly discharged through the opening groove 114, thereby better avoiding the problem of short circuit when the plug connector 100 and the socket connector 300 are plugged in, thereby improving the service life of the connector assembly 10.

[0048] like Figure 3 As shown, further, the opening groove 114 includes a low opening groove 114a and a high opening groove 114b, and both the low opening groove 114a and the high opening groove 114b are connected to the plug slot 112. The low opening groove 114a is arranged corresponding to the power contact 120, so that water or debris around the power contact 120 can be discharged to the periphery of the plug body 110 through the low opening groove 114a. The high opening groove 114b is arranged corresponding to the signal contact 130, so that water or debris around the signal contact 130 can be discharged to the periphery of the plug body 110 through the high opening groove 114b. In this embodiment, the opening position of the low opening groove 114a is located at the bottom of the plug slot 112, so that water or debris in the plug slot 112 can be better discharged through the low opening groove 114a. There is a preset height between the opening position of the high-position opening groove 114b and the bottom of the plug-in slot 112, that is, with the bottom of the plug-in slot 112 as a reference surface, the opening position of the high-position opening groove 114b is higher than the opening position of the low-position opening groove 114a, so that water or debris in the plug-in slot 112 can be discharged through the low-position opening groove 114a first, and then discharged through the high-position opening groove 114b. In this way, the low-position opening groove 114a and the high-position opening groove 114b respectively serve the purpose of two-stage drainage of water or debris, and then the water or debris in the plug-in slot 112 can be reliably drained, thereby better improving the service life of the connector assembly 10.

[0049] like Figure 3As shown, in one embodiment, the inner wall of the plug slot 112 is respectively provided with a first step 112a and a second step 112b, and the power contact 120 is connected to the first step 112a, so that the power contact 120 is connected to the inner wall of the plug slot 112 through the first step 112a, and thus there is a certain distance between the position where the power contact 120 is connected to the first step 112a and the bottom of the plug slot 112, so that even if the water or debris in the plug slot 112 is not cleaned up, a short circuit problem is not likely to occur. Furthermore, the signal contact 130 is connected to the second step 112b, so that the signal contact 130 is connected to the inner wall of the plug slot 112 through the second step 112b, and then there is a certain distance between the position where the signal contact 130 is connected to the second step 112b and the bottom of the plug slot 112, so that even if the water or debris in the plug slot 112 is not cleaned up, it is not easy to cause a short circuit problem. In addition, the power contact 120 is connected to the first step 112a, so that the connector assembly 10 has better reliability. In this embodiment, the first step 112a and the second step 112b are both formed at the bottom of the plug slot 112, which is conducive to the axial plugging and unplugging of the plug connector 100 and the socket connector 300. In other embodiments, the first step 112a and the second step 112b are not limited to being formed at the bottom of the plug slot 112.

[0050] like Figure 2 As shown, in one embodiment, the plug connector 100 further includes a power plug seal 140, which is disposed on the first step 112a and is disposed around the power contact 120. The power plug seal 140 is used to elastically abut against the inner wall of the power plug kit 320 when the power contact 120 is plugged into the power plug kit 320, so that the plugging position of the power contact 120 and the power plug kit 320 is sealed and connected, so as to avoid the problem of short circuit caused by water or debris in the plug slot 112 entering during the plugging process of the power contact 120 and the power plug kit 320, and at the same time realize the reliable plug-in resistance and waterproof function of the power contact 120. In this embodiment, the power plug seal 140 is a sealing ring structure, and the power plug seal 140 is arranged around the outer peripheral wall of the first step 112a, so that the power plug seal 140 can reliably seal the plugging point between the power contact 120 and the power plug kit 320.

[0051] like Figure 2As shown, specifically, a first annular groove 1122 is formed on the outer peripheral wall of the first step 112a, and the power plug seal 140 is sleeved in the first annular groove 1122 and elastically abuts against the first step 112a, so that the power plug seal 140 is reliably installed and fixed on the outer peripheral wall surface of the first step 112a to avoid the problem of the power plug seal 140 easily falling off, or the movement during the plug-in and unplugging process of the power contact 120 and the power plug kit 320.

[0052] like Figure 2 As shown, in order to make the power plug seal 140 reliably elastically abut against the inner wall of the power plug kit 320, further, a first wave flange is formed on the outer peripheral wall of the power plug seal 140, so that the power plug seal 140 can better elastically abut against the inner peripheral wall of the power plug kit 320 after the power contact 120 and the power plug kit 320 are plugged in and out, thereby making the power plug seal 140 reliably elastically abut against the inner wall of the power plug kit 320.

[0053] like Figure 2 As shown, in one embodiment, the plug connector 100 also includes a signal plug seal 150, which is disposed on the second step 112b, and the signal plug seal 150 is disposed around the signal contact 130, and the signal plug seal 150 is used to elastically abut against the inner wall of the signal plug kit 330 when the signal contact 130 is plugged into the signal plug kit 330.

[0054] like Figure 2 and Figure 3 As shown, in one embodiment, the power contact 120 includes a positive contact 122 and a negative contact 124. The number of the first steps 112a is two, and the two first steps 112a are located on both sides of the second step 112b. The positive contact 122 and the negative contact 124 are connected to the two first steps 112a respectively. The positive contact 122 is used to be plugged into the positive plug kit 322 of the power plug kit 320, and the negative contact 124 is used to be plugged into the negative plug kit 324 of the power plug kit 320, so that the plug connector 100 is electrically connected to the socket connector 300. In this embodiment, the number of the low-position opening slots 114a is two, and the two low-position opening slots 114a are respectively opened corresponding to the positive contact 122 and the negative contact 124, so that the water or debris in the plug slot 112 can be quickly and effectively discharged outside the plug body 110 at the positions corresponding to the positive contact 122 and the negative contact 124.

[0055] like Figure 2 and Figure 4As shown, in one embodiment, the power plug kit 320 includes a positive plug kit 322 and a negative plug kit 324. The number of the first receiving grooves 312a is two, and the positive plug kit 322 and the negative plug kit 324 are respectively located in the two first receiving grooves 312a, so that the positive plug kit 322 and the negative plug kit 324 are both fixedly connected to the socket body 310. The number of the first connecting grooves is two, and the two first connecting grooves are connected to the two first receiving grooves 312a in a one-to-one correspondence, and the two first steps 112a are arranged in the two first connecting grooves in a one-to-one correspondence. In this embodiment, the positive plug kit 322 is plugged into the positive contact 122, so that the positive plug kit 322 is electrically connected to the positive contact 122. The negative plug kit 324 is plugged into the negative contact 124, so that the negative plug kit 324 is electrically connected to the negative contact 124.

[0056] like Figure 4 As shown, further, the inner diameter of the negative electrode plug kit 324 is equal to the inner diameter of the positive electrode plug kit 322, and the inner walls of the negative electrode plug kit 324 and the positive electrode plug kit 322 are both provided with torsion springs, so that the negative electrode contact 124 is elastically plugged with the negative electrode plug kit 324, and the positive electrode contact 122 is elastically plugged with the positive electrode plug kit 322. Further, the diameter of the end of the positive electrode contact 122 exposed in the plug slot 112 is smaller than the diameter of the end of the negative electrode contact 124 exposed in the plug slot 112. In the process of the plug connector 100 being inserted into the socket connector 300, the negative electrode contact 124 first contacts with the torsion spring on the inner wall of the negative electrode plug kit 324, and then the plug connector 100 and the socket connector 300 are inserted for a distance, and finally the positive electrode contact 122 contacts with the torsion spring on the inner wall of the positive electrode plug kit, thereby avoiding the problem that the positive electrode contact 122 contacts first and is prone to sparks or even ablation due to excessive voltage. In addition, the positive contact 122 will contact the torsion spring in the positive plug-in kit only after the plug connector 100 and the socket connector 300 are inserted a certain distance, thereby avoiding the problem of deflection after the plug body 110 and the socket body 310 are plugged in.

[0057] like Figures 2 to 4As shown, in this embodiment, the number of the power plug seal 140 and the first step 112a are both two, and the two power plug seals 140 are respectively arranged on the two first steps 112a.

The power contact 120 includes a positive contact 122 and a negative contact 124, and the positive contact 122 and the negative contact 124 are respectively connected to the two first steps 112a. The power plug kit 320 includes a positive plug kit 322 and a negative plug kit 324, and the positive plug kit 322 and the negative plug kit 324 are respectively located in the two first receiving grooves 312a, so that the positive plug kit 322 and the negative plug kit 324 are both fixedly connected to the socket body 310. When the positive plug-in kit 322 is plugged into the positive contact 122, and the negative plug-in kit 324 is plugged into the negative contact 124, the power plug-in seal 140 on the first step 112a corresponding to the positive contact 122 elastically abuts against the inner wall of the positive plug-in kit 322, and the power plug-in seal 140 on the first step 112a corresponding to the negative contact 124 elastically abuts against the inner wall of the negative plug-in kit 324, so that the plug connector 100 and the socket connector 300 are tightly plugged. When the plug connector 100 and the socket connector 300 are fully mated, the power plug-in seal 140 is inserted into the first receiving groove 312a in the sealing area of ​​the plug body 110 and the socket body 310 plug-in interface, so as to achieve the sealing of the plug-in area of ​​the positive and negative power contact areas of the plug connector 100 and the socket connector 300.
