Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0036] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0037] See Figure 2 The present invention discloses a wire end connector 10, including an insulating body 11 and a wire end crimping terminal assembly 12 mounted on the insulating body 11. The insulating body 11 may be generally columnar in shape and may be made of an insulating material, including but not limited to plastic.

[0038] The wire-end crimping terminal assembly 12 includes a plurality of wire-end crimping terminals 121 and wires 122 connected to the wire-end crimping terminals 121. A waterproof plug 13 is provided at the connection point between the wires 122 and the wire-end crimping terminals 121 to improve waterproof sealing performance. A first waterproof ring 14 is provided on the circumferential outer surface of the insulating body 11. The first waterproof ring 14 is generally ring-shaped and may be, but is not limited to, a silicone sealing ring or a rubber sealing ring. The first waterproof ring 14 can be fitted onto the circumferential outer surface of the insulating body 11, so that when the wire-end connector 10 is plugged into the board-end connector 20, the outer surface of the first waterproof ring 14 can abut against the inner wall of the outer shell 21 of the board-end connector 20, thereby improving waterproof sealing performance. Furthermore, the two opposite outer sides of the insulating body 11 are provided with latches 15, which makes the connection between the wire end connector 10 and the board end connector 20 more stable when they are plugged in, and avoids the gap between them from increasing or the two from separating due to pulling or shaking, thereby improving stability.

[0039] like Figure 2 As shown, the outer periphery of the insulating body 11 is provided with an annular first mounting groove 111, and the first waterproof ring 14 is fitted into the first mounting groove 111. The first mounting groove 111 can play a role in limiting the installation of the first waterproof ring 14.

[0040] Understandably, the wire connector 10 improves its waterproof sealing performance by configuring a wire-crimping waterproof plug 13 and a first waterproof ring 14. The insulating body 11 has locking latches 15 on both opposite outer surfaces, which improves the installation stability of the wire connector 10 and prevents gaps from appearing during application, thus reducing its sealing performance.

[0041] like Figures 3 to 8 This application also discloses a connector assembly for transmitting current and signals, the connector assembly including a wire-end connector 10 (such as...). Figure 2 As shown), Figure 3 As shown, the connector assembly also includes a board-end connector 20 for insertion and fixation with the wire-end connector 10. The board-end connector 20 includes a housing 21 and a connector body 22 installed in the housing 21. The connector body 22 is generally cylindrical in shape. The connector body 22 may include a main body and a plurality of connecting terminals installed in the main body. A second waterproof ring 23 is provided on the circumferential outer side of the connector body 22, so that when the connector body 22 is installed into the inner cavity of the housing 21, the second waterproof ring 23 can abut against the inner wall of the housing 21 to improve the waterproof sealing performance.

[0042] The outer surfaces of the housing 21 are provided with latching portions 24 for engaging with the latch 15, making the connection between the wire connector 10 and the board connector 20 more secure when they are plugged in, preventing the gap between them from widening or the two from separating due to pulling or shaking, thus improving stability. The latching portion 24 may be, but is not limited to, a protruding structure or a slot structure.

[0043] Understandably, the connector assembly includes a wire-end connector 10 and a board-end connector 20. The wire-end connector 10 improves waterproof sealing performance by configuring a wire-press waterproof plug 13 and a first waterproof ring 14, etc. The board-end connector 20 has a second waterproof ring 23 on the circumferential outer side of the connector body 22, which improves waterproof sealing performance.

[0044] The insulating body 11 of the wire connector 10 is provided with two opposite outer sides of the locking buckle 15, and the outer sides of the shell 21 of the board connector 20 are provided with a fastening part 24 for engaging with the locking buckle 15. This makes the connection between the wire connector 10 and the board connector 20 more stable when they are plugged in, and avoids the situation where the gap between the wire connector 10 and the board connector 20 increases or the wire connector 10 and the board connector 20 separate due to pulling or shaking, thereby improving stability.

[0045] like Figure 3 As shown, the connector body 22 has an annular second mounting groove 221 on its outer periphery. The second waterproof ring 23 is fitted into the second mounting groove 221, and the second mounting groove 221 can limit the installation of the second waterproof ring 23. The second waterproof ring 23 can be, but is not limited to, a silicone sealing ring or a rubber sealing ring.

[0046] like Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, the inner sidewall of the housing 21 has a protrusion 211, and the outer periphery of the connector body 22 has a latch 222 for engaging with the protrusion 211. When the connector body 22 is installed inside the housing 21, the latch 222 may be located on the protrusion 211, allowing the connector body 22 to have a floating distance X within the housing 21. The maximum value of the floating distance X may be 2 mm. Figure 8 As shown, when the connector body 22 moves downward, the latch 222 abuts against the protrusion 211, preventing the connector body 22 from moving downward.

[0047] like Figure 3 , Figure 4 , Figure 6As shown, in some embodiments, the inner sidewall of the housing 21 is provided with a limiting portion 212, and the outer periphery of the connector body 22 is provided with a protruding rib 223 for cooperating with the limiting portion 212. The limiting portion 212 may be located on the lower side of the protrusion 211, and the protruding rib 223 may be located on the lower side of the latch 222. For example... Figure 6 As shown, when the connector body 22 moves up and down inside the housing 21, for example, when it moves upward, at the extreme position, the protruding rib 223 abuts against the limiting part 212, so that the connector body 22 can no longer move upward. For example, the upper surface of the protruding rib 223 abuts against the lower surface of the limiting part 212, so that the connector body 22 can no longer move upward.

[0048] In some embodiments, two ribs 223 are provided on one side of the outer periphery of the connector body 22 (e.g., Figure 3 As shown), a rib 223 is provided on the other side of the outer periphery of the connector body 22 (as shown). Figure 4 As shown in the figure, of course, the number and position of the ribs 223 can be selected according to actual needs, and no specific limitation is made here.

[0049] In some embodiments, the upper surface of the rib 223 is a plane, and the lower surface of the limiting portion 212 is also a plane.

[0050] like Figures 6 to 8 In some embodiments, the outer side of the housing 21 also extends a mounting plate 25 (in conjunction with...). Figure 3 As shown), the upper surface of the mounting plate 25 is provided with a third waterproof ring 26. The mounting plate 25 is used to connect with the cabinet panel 30 (as shown). Figure 7 and Figure 8 The connection (shown) can be made via fastener 40. The third waterproof ring 26 can be approximately square-shaped and located between the mounting plate 25 and the cabinet panel 30 to improve waterproof sealing performance. The third waterproof ring 26 can be, but is not limited to, a silicone sealing ring or a rubber sealing ring.

[0051] like Figure 6 As shown, in some embodiments, the upper surface of the mounting plate 25 is provided with an annular third mounting groove 251, and the third waterproof ring 26 is installed in the third mounting groove 251. The third mounting groove 251 can limit the installation of the third waterproof ring 26.

[0052] like Figure 3As shown, the mounting plate 25 is provided with a plurality of mounting cylinders 252, which may be located at the four corners of the mounting plate 25, and the upper end of the mounting cylinder 252 protrudes from the upper surface of the mounting plate 25. The third waterproof ring 26 is annular and is provided with a plurality of through holes 261 that mate with the upper part of the mounting cylinder 252.

[0053] Combination Figures 9 to 11 As shown, the fastener 40 passes through the cabinet panel 30 and the through hole 261 in sequence and is installed into the mounting cylinder 252 to fix the board end connector 20 and the cabinet panel 30. The inner wall of the mounting cylinder 252 may be provided with internal threads, and the fastener 40 includes, but is not limited to, fastening bolts or fastening screws.

[0054] like Figure 11 As shown, in some embodiments, the lower end face of the connector body 22 is also provided with waterproof adhesive 27 to improve waterproof performance.

[0055] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
