Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of providing a cable pass-through for external cables with external connectors at the end, and more particularly to a cable pass-through connector for a power supply unit with external connectors at the end and a cable pass-through box having the cable pass-through connector. Background Technology
[0002] For example, at Figure 1 and Figure 2 In the existing junction box 100, a cap-type cable guide 10 is provided for the external cable 210 of the motor 200 enclosed by the junction box 100 to pass through. In order to facilitate quick connection and disconnection of the motor 200 to the outside world by plugging and unplugging, the ends of the external cables 210 of the motor 200 are all pre-installed with external connectors 220, and the size of the external connectors 220 is larger than the wire diameter of the external cables 210.
[0003] However, since the cable guide hole 11' of the cap-type cable guide 10' is matched with the wire diameter of the external cable 210, the external connector 220 cannot pass through the cable guide hole 11' of the cap-type cable guide 10'. The external connector 220 can only be removed from the external cable 210, and then the end of the external cable 210 can be passed through the cable guide hole 11' of the cap-type cable guide 10', and then the external connector 220 can be assembled onto the end of the external cable 210. This results in the existing cable box 100' having the defect of troublesome cable passing operation, especially when the cap-type cable guide 10' needs to waterproof and seal the external cable 210, which causes the diameter of the cable guide hole 11' to be made smaller than the wire diameter of the external cable 210, making the cable passing operation even more troublesome.
[0004] Therefore, there is an urgent need for a cable connector and a cable box having the cable connector to overcome one or more of the above-mentioned defects. Utility Model Content

[0038] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0039] Please see Figures 3 to 6 The cable tray 100 of this utility model includes a cable connector 10 and a box body 20 for enclosing the motor 200. Optionally, it is... Figures 4 to 6 As an example, the housing 20 includes a top cover 20a and a bottom plate 20b. The top cover 20a covers the bottom plate 20b from above and is assembled with it to facilitate the installation and removal of the external motor 200 from the housing 20. This is because the operator first assembles the motor 200 onto the bottom plate 20b, and then assembles the top cover 20a onto the bottom plate 20b; therefore, the assembly and removal of the motor 200 onto the bottom plate 20b is not constrained by the top cover 20a. It should be noted that when a seal is required at the joint between the top cover 20a and the bottom plate 20b, a sealing element can be provided between the top cover 20a and the bottom plate 20b, but this is well known in the art and will not be elaborated upon here. Furthermore, regarding... Figures 3 to 6 In this example, the top cover 20a is assembled and connected to the base plate 20b by means of fixing screws; obviously, depending on actual needs, the assembly and connection method between the top cover 20a and the base plate 20b can also be other methods well known in the art, so it is not used as an example. Figures 3 to 6 The above is the limit.
[0040] Combined Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 14 The cable connector 10 includes a base 11, an end cap 12, and a fastener 13. The base 11 has a through hole 111 and a first through groove 112 arranged in a through-hole configuration. The first through groove 112 communicates with the through hole 111 at its periphery. The area of the first through groove 112 is smaller than the area of the through hole 111 to accommodate the external connector 220 on the external cable 210 of the motor 200 passing through the through hole 111 and the external cable 210 being placed in the first through groove 112. Optionally, in... Figure 14 In the example, through hole 111 is a rectangular hole, such as, but not limited to, other types of holes. Figure 14 The rectangular hole shown has rounded chamfers at the four corners; obviously, depending on actual needs, the shape of the through hole 111 can also be other shapes well known in the art, such as a square, so it is not specified. Figure 14 The description is for illustrative purposes only. Additionally, the base 11 is mounted on the housing 20, and the through hole 111 communicates with the internal space 21 of the housing 20, allowing the external connector 220 on the external cable 210 of the power supply 200 to pass through the through hole 111 and the external cable 210 of the power supply 200 to pass through the cable hole 10a described below, as shown in the diagram. Figure 3 As shown; alternatively, at Figures 3 to 6 In this example, the base 11 is located on the side wall 22 of the top cover 20a in the box 20, but is not limited thereto.
[0041] End cap 12 is stacked on base 11 in the direction of the through hole 111 (see arrow A) and covers the through hole 111. End cap 12 also has a second through groove 121 that is arranged through the hole and mates with the first through groove 112. The second through groove 121 and the first through groove 112 are combined to form a wire through hole 10a, as shown in the figure. Figure 7 and Figure 8 As shown; alternatively, at Figures 10 to 14 In this example, the first through slot 112 and the second through slot 121 are both arc-shaped slots, such as, but not limited to, semi-circular arc-shaped slots, so that the wire hole 10a formed by the first through slot 112 and the second through slot 121 is a circular hole, thereby better matching the outer contour of the motor 200's external cable 210, which is circular; that is, the shapes of the first through slot 112 and the second through slot 121 are adapted to the outer contour of the motor's external cable 210.
[0042] Fastener 13 is inserted into the base 11 and end cap 12, fixing the base 11 and end cap 12 together, thus achieving a fixed connection between the end cap 12 and the base 11; and since the base 11 is fixed to the box 20, the purpose of fixing the end cap 12, base 11, and box 20 together is achieved. Specifically, in Figure 9 , Figure 12 and Figure 13 In one example, the side 11a of the base 11 facing away from the end cap 12 is stacked on the box body 20. A sealing ring 15 is also provided between the side 11a of the base 11 facing away from the end cap 12 and the box body 20, arranged around the through hole 111, to achieve a seal between this side 11a and the box body 20. Alternatively, in... Figure 12 and Figure 13As an example, the seat 11 has a closed annular groove 118 arranged around the through hole 111 on the side 11a opposite to the end cover 12, and the sealing ring 15 is fitted onto the closed annular groove 118; in addition, the seat 11 can be fixed to the box 20 by means of mounting screws. More specifically, see the description below.
[0043] Combination Figure 9 and Figures 11 to 13 As an example, the base 11 has a first mounting hole 113, which is spaced apart from the first through groove 112 and allows the fastener 13 to pass through. The end cap 12 also has a second mounting hole 122, which is spaced apart from the second through groove 121 and allows the fastener 12 to pass through. The wall of the second mounting hole 122 has a center line relative to the center line of the second mounting hole 122 (visible). Figure 9 The inclined structure 1221 (with the center line in the middle) is inclined in the direction close to the seat 11 (visible) Figure 9 (As indicated by arrow A in the image) the center line of the hole closest to the second assembly hole 122 (visible) Figure 9 The center line of the motor is arranged. Therefore, during the process of fastener 13 fixing the base 11 and end cover 12 together, fastener 13 drives end cover 12 to move by reducing the size of the wire hole 10a through the inclined structure 1221. That is to say, fastener 13 applies force to end cover 12 in the direction indicated by arrow A, and also applies force to end cover 12 in the direction indicated by arrow B, so that end cover 12 and base 11 jointly hold the external cable 210 of motor 200 that passes through the wire hole 10a, thus making the external cable 210 more stable. Specifically, in Figure 9 and Figure 11 As an example, fastener 13 has a sloping abutment structure 131 that engages with the sloping structure 1221 at an angle. Alternatively, the sloping abutment structure 131 may surround the centerline of fastener 13 (see image). Figure 9 The inclined structure 131 extends along the center line of the second assembly hole 122 (visible). Figure 9 The fastener 13 extends along the center line of the motor 200. Therefore, during the process of fastening the seat 11 and end cap 12 together, the fastener 13 continuously drives the end cap 12 to move through the narrowing cable hole 10a during rotation, more effectively ensuring the reliability of the external cable 210 passing through the cable hole 10a, which is held by the end cap 12 and seat 11 together. More specifically, the fastener 13 is a screw, and the first mounting hole 113 is a threaded hole, simplifying the structure of the fastener 13 fixing the seat 11 and end cap 12 together. Obviously, depending on actual needs, the fastener 13 can also be other structures known in the art, therefore, it is not specified that... Figure 9 The above is the limit.
[0044] Combination Figures 9 to 14As an example, the seat 11 has a first end face 114 that mates with the end cap 12 in the through-hole 111 direction, a connecting surface 115 that mates with the end cap 12 in the direction in which the second through groove 121 aligns with the first through groove 112 (see the direction indicated by arrow B), and a second end face 116 that is misaligned relative to the first end face 114 in the through-hole 111 direction. The end cap 12 correspondingly has a first mating surface 123 that mates with the first end face 114 and a second mating surface 124 that mates with the connecting surface 115. The second mating surface 124 can fit against the connecting surface 115 during the process of the fastener 13 fixing the seat 11 and the end cap 12 together. That is, after the seat 11 and the end cap 12 are fixed together, there is no gap between the connecting surface 115 and the second mating surface 124, as shown in the diagram. Figure 9 As shown. At this time, the through hole 111 penetrates the first end face 114, and the first through groove 112 penetrates the second end face 116, as shown in the diagram. Figure 10 , Figure 11 and Figure 14 As shown. Specifically, in conjunction with Figures 9 to 14 As an example, the first end face 114, connecting surface 115, second end face 116, first mating surface 123, and second mating surface 124 are all flat surfaces. Optionally, the first end face 114 and connecting surface 115 are arranged at right angles, and the first mating surface 123 and second mating surface 124 are arranged at right angles. This design allows the base 11 and end cover 12 to fit together surface-to-surface, increasing the reliability of their fixation. In addition, the base 11 also has a through-face that passes through both the first end face 114 and the second end face 116. An open annular groove 117 is arranged around the through hole 11 and the connecting surface 115. The two open ends 1171 of the open annular groove 117 are located on the second end face 116. An open sealing ring 14 is correspondingly embedded in the open annular groove 117. The open sealing ring 14 also abuts against the first mating surface 123 and the second mating surface 124. The open sealing ring 14 is used to achieve a seal between the first end face 114 and the first mating surface 123 and between the connecting surface 115 and the second mating surface 124. It should be noted that since the open sealing ring 14 is an open ring, the two ends 141 of the open sealing ring 14 are respectively placed in the ends 1171 of the corresponding open annular groove 117.
[0045] Among them, Yu Figure 7 and Figures 9 to 11As an example, the end cap 12 has a protruding structure 125 on the side 12a opposite to the base 11, which protrudes from the second mating surface 124 in the direction in which the second through groove 121 is joined to the first through groove 112. The protruding structure 125 has a third mating surface 1251 that mates with the second end face 124. This design allows the protruding structure 125 to cover the mating area between the connecting surface 115 and the second mating surface 124, so that liquid falls along the protruding structure 125 under its own weight, preventing liquid from entering from the mating area between the connecting surface 115 and the second mating surface 124. Furthermore, since the external cable 210 of the motor 200 is made of insulating material, when the end cap 12 and the base 11 tightly hold the external cable 210, liquid can be prevented from passing between the external cable 210 and the cable hole 10a. Specifically, in Figure 9 In the example, the third mating surface 125 is a flat surface, and the third mating surface 125 and the second mating surface 124 are arranged at right angles to achieve a planar fit between the third mating surface 125 and the second end face 115, and to achieve a planar fit between the connecting surface 114 and the second mating surface 124.
[0046] Compared with the prior art, during the wire-passing operation, the external connector 220 on the external cable 210 of the motor 200 is first passed through the through hole 111 of the base 11, and one side of the external cable 210 of the motor 200 (for example, see...) Figure 3 The lower side of the end cap 12 enters the first through slot 112; then, the second through slot 121 of the end cap 12 is made to open from the opposite side of the external cable 210 of the motor 200 (see, for example, see...). Figure 3 The external cable 210 is assembled on the upper side of the end cover 12 until it enters the preset position of the second through slot 121 of the end cover 12 on the opposite side. Then, the end cover 12 and the base 11 are fixed together by the fastener 13. Therefore, during the wire passing operation, it is not necessary to disassemble and reassemble the external connector 220 on the external cable 210 of the motor 200, thus simplifying the wire passing operation.
[0047] It should be noted that, with the cooperation of the open sealing ring 14, the closed sealing ring 15, and the protruding structure 125, the purpose of the cable box 100 of this utility model can be achieved to prevent liquid from entering the internal space 21 of the box body 20 of the cable box 100 from the outside. Furthermore, the aforementioned open sealing ring 14 refers to the fact that its two ends 141 are open in the circumferential direction, rather than connected together; the aforementioned closed sealing ring 15 refers to the fact that its two ends are connected together in the circumferential direction.
[0048] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
