DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

[0035] In the description of the present application, it should be understood that the terms "first", "second" are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, at least one of which can be one, two or more, unless otherwise specifically limited.

[0036] As an introduction to the embodiments of the present application, a connecting device is introduced. The male and female plug ends are currently a common electrical connecting device. When producing and processing, the wire harness needs to be connected with the male and female plug ends in order to transmit electrical signals. However, there is often a gap between the connection of the wire harness and the plug end. The wire harness is thin, and it is difficult to achieve sealing between the wire harness and the male and female plug end in the form of a sealing ring or a sealing gasket. The gap at the connection between the thin wire harness and the plug end may not be able to accommodate the sealing ring, or the size of the sealing ring may not be able to match the structure of the male and female plug. The sealing of the connection between the wire harness and the male and female plug end is relatively low, and cannot meet the higher protection level (wherein, the high protection level usually needs to protect the electrical connection from dust, moisture, vibration and other harsh environments).

[0037] Therefore, the embodiments of the present application provide a connecting device to overcome at least one of the above technical problems.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3In the embodiment of the present application, the connecting device comprises a first connecting piece 10, a first connecting wire 20 and a first filling piece 30. The first connecting piece 10 has a first wire slot 11, and one or more first wire slots 11 can be provided so that one or more first connecting wires 20 can be connected to the first connecting piece 10. The first connecting piece 10 can be a male plug end of a plug end assembly, or a female plug end. The first connecting wire 20 is arranged in the first wire slot 11 and connected to the first connecting piece 10, and the first connecting wire 20 is an electric wire or a wire harness. The first connecting piece 10 is provided with the first wire slot 11 through which the first connecting wire 20 penetrates, and the first wire slot 11 is in communication with the slot into which the first connecting wire 20 is originally inserted. After the first connecting wire 20 penetrates the first wire slot 11, it is embedded in the slot originally provided in the first connecting piece 10 for inserting the electric wire or the wire harness, and is electrically connected to the corresponding contact in the slot. The first filling piece 30 is filled in the first wire slot 11 and seals the connection between the first connecting piece 10 and the first connecting wire 20. The first filling piece 30 can be glue, which is in a liquid state and is filled in the first wire slot 11. After it solidifies, it can form a stable filling state in the first wire slot 11, so that there is no gap between the first connecting wire 20 and the inner wall of the first wire slot 11, thereby improving the sealing performance of the connection between the first connecting wire 20 and the first connecting piece 10, preventing foreign matters such as dust and water stains from entering the interior of the first connecting piece 10, and meeting a higher protection level. The first filling piece 30 can also be plastic, rubber or the like, which is in a molten state and is placed in the interior of the first wire slot 11. After it cools and solidifies, it can be stably filled in the first wire slot 11 and seal the connection between the first connecting wire 20 and the first connecting piece 10, effectively improving the sealing performance of the connection.

[0039] Please refer to Figure 1 and Figure 2In some embodiments, the connecting device further comprises a second connecting piece 40, a second connecting wire 50 and a second filling piece 60. The second connecting piece 40 is inserted into the first connecting piece 10 and electrically connected with the first connecting piece 10. The second connecting piece 40 has a second wire slot 41. The second connecting wire 50 is inserted into the second wire slot 41 and electrically connected with the second connecting piece 40. The second filling piece 60 is filled into the second wire slot 41 and seals the second connecting piece 40 and the second connecting wire 50. The second connecting piece 40 can be another insertion end matched with the first connecting piece 10 and electrically connected with the first connecting piece 10. One or more second wire slots 41 can be arranged on the second connecting piece 40, so that the second connecting piece 40 can also connect one or more second connecting wires 50. After the second connecting wire 50 is inserted into the second wire slot 41, the second connecting wire 50 can be embedded into the slot originally for the insertion of the second connecting wire 50 and electrically connected with the corresponding contact in the slot. Through the connection of the corresponding contacts on the first connecting piece 10 and the second connecting piece 40, the first connecting wire 20 and the second connecting wire 50 are electrically connected. The second filling piece 60 and the first filling piece 30 have the same material and function. By filling the second filling piece 60 into the second wire slot 41, the connection between the second connecting piece 40 and the second connecting wire 50 will not have gaps, so as to achieve the purpose of sealing the second connecting piece 40 and the second connecting wire 50.

[0040] Referring to Figure 2 and Figure 4 In some embodiments, the first wire slot 11 has a first opening 111 opposite to the bottom wall of the first wire slot 11, and the first connecting wire 20 is inserted into the first wire slot 11 from the first opening 111. In the thickness direction X of the first connecting wire 20, the first wire slot 11 has a first size L1, which decreases from the first opening 111 to the bottom wall of the first wire slot 11. The first connecting wire 20 penetrates the inside of the first wire slot 11 from the direction of the first opening 111 to the bottom wall of the first wire slot 11. Since the first filling piece 30 is in a liquid state during the filling process, in order to facilitate the filling of the first filling piece 30 in the first wire slot 11, so that the first filling piece 30 can fill the entire first wire slot 11, the first size L1 of the first wire slot 11 in the thickness direction X gradually decreases from the first opening 111 to the bottom wall of the first wire slot 11. That is, the opening of the first wire slot 11 has a structure similar to a horn, and the opening of the first wire slot 11 becomes smaller and smaller towards the inside of the first wire slot 11. Through this gradually decreasing structure, when the first filling piece 30 in a liquid state is poured into the first wire slot 11, the first filling piece 30 can quickly fill the inside of the first wire slot 11 and be filled sufficiently without gaps, so as to improve the sealing effect of the connection between the first connecting wire 20 and the first connecting piece 10.

[0041] Referring to Figure 2In some embodiments, the second wiring slot 41 has a second opening 411 opposite to the bottom wall of the second wiring slot 41, and the second connecting line 50 is arranged in the second wiring slot 41 from the second opening 411. In the thickness direction X of the second connecting line 50, the second wiring slot 41 has a second size L2 from the second opening 411 to the bottom wall of the second wiring slot 41, and the second size L2 decreases. In the second wiring slot 41, the second opening 411 is provided for the second connecting line 50 to pass through, and similarly, the smaller the opening of the second wiring slot 41 is, the closer to the inside of the second wiring slot 41. That is, in the direction from the second opening 411 to the bottom wall of the second wiring slot 41, the second size L2 of the second wiring slot 41 in the thickness direction X gradually decreases. Through this gradually decreasing structure, when the second filler 60 is poured into the second wiring slot 41, the second filler 60 in a liquid state can quickly fill the inside of the second wiring slot 41 and be filled sufficiently without gaps, so that the sealing effect of the connection between the second connecting line 50 and the second connecting piece 40 can be improved.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In some embodiments, the first connecting piece 10 includes a first body 12 and a first insertion part 13 connected to the first body 12. The first wiring slot 11 is arranged in the first body 12, and the first insertion part 13 includes a first contact 131, and the first connecting line 20 is electrically connected to the first contact 131. The second connecting piece 40 includes a second body 42 and a second contact 43, the second body 42 has a mating slot 421, the second contact 43 is arranged in the mating slot 421 and is electrically connected to the second connecting line 50; the first insertion part 13 is inserted into the mating slot 421, and the first contact 131 is electrically connected to the second contact 43. The first insertion part 13 can be inserted into the mating slot 421 of the second connecting piece 40, so that the first connecting piece 10 and the second connecting piece 40 can be electrically connected. Specifically, a plurality of first contacts 131 electrically connected to the first connecting line 20 can be arranged on the first insertion part 13, and a plurality of second contacts 43 are arranged on the second connecting piece 40. By electrically connecting the first contact 131 to the corresponding second contact 43 on the second connecting piece 40, the first connecting line 20 and the second connecting line 50 are electrically connected.

[0043] The connecting device further comprises a sealing member 70, which is sleeved on the first insertion part 13 and seals the first insertion part 13 and the second body 42. After the first insertion part 13 is inserted into the mating groove 421, the sealing member 70 on the surface of the first insertion part 13 is also inserted into the mating groove 421, and the outer surface of the sealing member 70 can be in close contact with the inner wall of the mating groove 421, so that the sealing property between the sealing member 70 and the inner wall of the mating groove 421 is improved, and water stains and dust and other foreign matters are prevented from entering the mating groove 421, thereby avoiding affecting the connection of the corresponding contacts.

[0044] Please refer to Figure 5 In some embodiments, the sealing member 70 comprises a guide slope 71, which is inclined to the first direction Y. The first direction Y corresponds to the direction in which the first insertion part 13 is inserted into the mating groove 421, so that the guide slope 71 can guide the first insertion part 13 into the mating groove 421. The first direction Y intersects the thickness direction X, and preferably, the first direction Y is perpendicular to the thickness direction X. During the process of inserting the first insertion part 13 into the mating groove 421, the guide slope 71 on the sealing member 70 will first enter the inside of the mating groove 421. Since the guide slope 71 is inclined to the first direction Y and in order to smoothly guide the first insertion part 13 into the mating groove 421, the front end of the guide slope 71 has a large spacing with the inner wall of the mating groove 421 when entering the mating groove 421 along the first direction Y, so that the front end of the guide slope 71 is more easily inserted into the inside of the mating groove 421. The sealing member 70 can play a certain guiding role while achieving the sealing effect, and the sealing member 70 will not hinder the first insertion part 13, but will make the process of inserting the first insertion part 13 into the mating groove 421 more convenient and fast.

[0045] Please refer to Figure 5 In some embodiments, the sealing member 70 comprises a first sealing part 72 and a second sealing part 73 connected with each other, the first sealing part 72 and the second sealing part 73 are arranged in the first direction Y, the first sealing part 72 and the second sealing part 73 are both sleeved on the first insertion part 13, and the guide slope 71 is arranged on the second sealing part 73. The sealing member 70 can be composed of two parts, i.e., the first sealing part 72 and the second sealing part 73, both of which are sleeved on the first insertion part 13 and arranged in the first direction Y. The guide slope 71 is arranged on the second sealing part 73, so that the second sealing part 73 is first embedded into the mating groove 421 during the process of embedding the first insertion part 13 into the mating groove 421, and the guide slope 71 thereon can guide the embedding of the first insertion part 13, thereby facilitating the fast embedding of the first insertion part 13.

[0046] Please refer to Figure 5In some embodiments, in the first direction Y, the guide slope 71 comprises opposite first and second ends 711 and 712, the second end 712 is connected with the first sealing part 72, and the distance between the guide slope 71 and the first insertion part 13 gradually increases from the first end 711 to the second end 712. Specifically, the second end 712 on the guide slope 71 is connected with the first sealing part 72, and after the sealing member 70 is sleeved on the first insertion part 13, the distance between the guide slope 71 and the first insertion part 13 gradually increases from the first end 711 to the second end 712, that is, the minimum distance from the first end 711 to the first insertion part 13 is smaller than the minimum distance from the second end 712 to the first insertion part 13, so that the guide slope 71 presents an inclined shape, facilitating the guiding of the first insertion part 13 during the insertion of the first insertion part 13 into the docking groove 421.

[0047] Referring to Figure 5 In some embodiments, the second sealing part 73 comprises a plurality of guide slopes 71, the plurality of guide slopes 71 are arranged around the first insertion part 13, and at least two guide slopes 71 are arranged opposite to each other. The guide slope 71 can be provided in plurality and arranged around the first insertion part 13, and preferably, the two opposite surfaces on the second sealing part 73 are provided as guide slopes 71. Through the two opposite guide slopes 71, the first insertion part 13 can be guided in two directions, thereby improving the guiding effect. Similarly, if all the opposite surfaces are provided as guide slopes 71, the guiding effect of the second sealing part 73 can be further improved.

[0048] Referring to Figure 2 、 Figure 4 、 Figure 6 and Figure 7 In some embodiments, the first connector 10 further comprises a buckle part 14 arranged on the first insertion part 13, and the second connector 40 further comprises a clamping groove part 44 arranged in the docking groove 421, and the buckle part 14 and the clamping groove part 44 are connected in a clamping manner. The buckle part 14 is connected on the first insertion part 13 of the first connector 10, the clamping groove part 44 is arranged in the inner part of the docking groove 421, the number and position of the buckle part 14 and the clamping groove part 44 correspond to each other, the buckle part 14 can be a buckle protrusion, a clamping block or the like structure, and the clamping groove part 44 can be a buckle recess, a clamping groove or the like structure matched with the buckle part 14, the clamping groove can be formed by recessing the inner wall of the docking groove 421 or can be formed by penetrating the inner wall of the docking groove 421. After the first insertion part 13 is embedded into the inner part of the docking groove 421, the buckle part 14 and the clamping groove part 44 are connected in a clamping manner, which can improve the firmness of the connection between the first insertion part 13 and the second connector 40, ensure good connection effect, and avoid easy loosening after connection.
