Description

Technical Field

[0001] The present invention relates to the technical field of wire harness connectors, and specifically to a connector with excellent insulation performance. Background Art

[0002] A wire harness is the overall equipment that provides services for a certain group of traffic sources, such as relay lines, switching devices, control systems, etc. According to different structures, wire harnesses are divided into fully utilized wire harnesses, partially utilized wire harnesses, and link systems; according to different service methods, they are divided into loss systems and waiting systems (see random service systems); according to the number of traffic sources served, they are divided into infinite traffic source wire harnesses and finite traffic source wire harnesses.

[0003] In a telecommunication system, the devices directly used for communication between users are mostly infinite traffic source loss system fully utilized link systems, while the devices used to control the connection process of communication devices are mostly infinite traffic source waiting system fully utilized systems. When the number of traffic sources is not very large relative to the capacity of the wire harness, a fully utilized system or a partially utilized system with finite traffic sources is generally adopted.

[0004] In order to apply wire harnesses to various devices and systems, terminals are often crimped at both ends of the wire harness, and the terminals are inserted into the interior of the wire harness connector to complete the connection work between different wire harnesses and between the wire harness and the device. A connector generally refers to an electrical connector, which bridges the gap at the blocked or isolated part of the circuit to allow current to flow and enable the circuit to achieve the intended function.

[0005] The patent document with the publication number CN214625473U, a connector with excellent insulation performance, has connection heads provided at both the upper and lower ends of the body. A group of glass rings are fixedly installed at the lower end of each group of connection heads through a base. The glass rings have excellent insulation properties. At the same time, the glass rings are designed in different colors so that the glass rings on the upper and lower corresponding connection heads are of the same color, which is convenient for the staff to organize the wires. At the same time, rubber rings are provided on the connecting pieces at the lower ends of the connection heads. The rubber rings also have excellent insulation properties, further improving the insulation performance of the present utility model;

[0006] The patent document with the publication number CN214625473, an easily assembled terminal wire harness connector, through the provided insulating sheath, makes the insulating effect of the connector better and the safety performance of the connector stronger. When in use, the first sheath penetrates the installation groove, and the first sheath is locked and adjusted by threads inside the connecting sleeve. The opening of the first through groove facilitates the installation of the insert piece. The setting of the installation sleeve facilitates the installation and connection between the connecting sleeve and the second sheath. The second through groove opened inside the second sheath facilitates the installation of the plug spring. The openings of the first circular groove and the second circular groove facilitate the installation of the second wire harness and the first wire harness. The setting of the first limiting circular piece plays a certain limiting role for the insert piece, and the setting of the second limiting circular piece plays a certain limiting role for the plug spring. The production material of the overall insulating sheath is insulating plastic, and the insulating effect is better.

[0007] However, in the process of implementing the above technical solution, the following technical problems are found in the above technical solution:

[0008] The connector with excellent insulation performance (publication number: CN214625473U) adopts a rubber ring arranged on the inner side of the insulating glass ring, so that the connector is located inside the rubber ring to improve the insulation performance of the connector. This method has a good insulation performance. However, in the actual operation process, the installation of the rubber ring and the glass ring needs to be completely matched, which easily increases the installation difficulty due to size deviation and takes a long time.

[0009] The easily assembled terminal wire harness connector (publication number: CN214625473U) adopts an insulating sheath to form a fully enclosed state outside the connector to ensure the insulating effect. However, in the process of removing the wire harness terminal, the fully enclosed state easily affects the operation, and the insulating layer is easily damaged during this process. Summary of the Invention

[0010] In order to overcome the deficiencies that the insulating layer of the connector in the prior art is either too tightly fitted or difficult to disassemble, the embodiment of the present application provides a connector with excellent insulation performance. By pressing one end of the sealing member into the inside of the connector plug A or the connector plug B, the plug head on one side of the plug cover is inserted into the inside of the connector plug A or the connector plug B. When the plug head passes through the inside of the sealing cotton pad, the extending cotton is received inside the wire routing groove opening. The sealing cotton pad can expand around to fill the space between the sealing member and the connector plug A or between the sealing member and the connector plug B, and the extending cotton fills the inside of the wire routing groove opening, eliminating the gaps between the wire and the inner wall of the connector plug A, the inner wall of the wire routing groove opening, or the connector plug B, the inner wall of the wire routing groove opening, so as to achieve the effect of separating the inside of the connector plug A and the connector plug B from the external environment, which can play the roles of isolating dust, water droplets and preventing electric shock, is easy to operate, and the sealing cotton pad is not easily damaged and is conducive to replacement;

[0011] Meanwhile, by means of the inclined surfaces at one end of the connector plug A and the connector plug B, a gap can be formed between the surface of the plug cover and the end face of the connector plug A or the connector plug B, which facilitates the control of the removal of the seal from the inside of the connector plug A or the connector plug B when the seal is inserted into the inside of the connector plug A or the connector plug B.

[0012] The technical solution adopted by the embodiment of the present application to solve its technical problems is as follows:

[0013] A connector with excellent insulation performance includes a connector plug A, a connector plug B, a seal, and a sealing cotton pad. The connector plug B is inserted into one end of the connector plug A.

[0014] There are two seals, which are respectively arranged at one end of the connector plug A and the connector plug B away from the mutual docking point; and

[0015] There are two sealing cotton pads, which are respectively used in combination with the two seals;

[0016] Wherein, the two sealing cotton pads are respectively embedded in one end of the connector plug A and the connector plug B away from the mutual docking point. The top and bottom of the connector plug A and the connector plug B are both provided with co-directional transmission structures. The connector plug A and the connector plug B are inserted into each other in opposite directions. The co-directional transmission structures drive the two seals to be respectively inserted into one end of the connector plug A and the connector plug B away from the mutual docking point, and expand the sealing cotton pads around.

[0017] In a possible implementation manner, the co-directional transmission structure includes a slide bar A. Rack teeth A are machined on both sides of the slide bar A. A gear is meshed and connected to one side of each of the two rack teeth A. A support shaft column is arranged inside the gear. A rack tooth B is meshed and connected to one side of the gear. A slide bar B is machined on one side of the rack tooth B. A support bar is arranged between one ends of the two slide bars B on the upper and lower parts of the connector plug A or the connector plug B. Shaft rods are machined at both ends of the support bar; Hooks are machined at the four corners at one end of the seal; The hooks on both sides of the seal are hooked from the center to the outside of the two support bars. The slide bar A drives the two rack teeth A to move towards one side of the seal. With the help of the two gears and the rack tooth B respectively supported by the two support shaft columns, the slide bar B pulls the hooks into the inside of one end of the connector plug B or the connector plug A, so that one end of the seal is plugged into the inside of the connector plug A or the connector plug B.

The two sliding strips B are slidably connected inside the positioning strip grooves B on both sides. The sliding strip A is slidably connected inside the positioning strip groove B at the center.

[0019] In a possible implementation, the receiving strip groove is also machined at the top and bottom of the center of the connector plug B. The limit strip groove is also machined at the top and bottom centers of the connector plug B. One end of the sliding strip A at the top and bottom of the connector plug B is machined with a push plate B. The surfaces of the two sliding strips A facing each other are machined with slide plates. The two sliding strips B are slidably connected inside the positioning strip grooves B on both sides. The sliding strip A is slidably connected inside the positioning strip groove B at the center. The slide plate is slidably connected inside the limit strip groove.

[0020] In a possible implementation, a plurality of wire routing slots are machined inside the seal. A plurality of extended wools are integrally formed at the inner wall of the sealing cotton pad. The plurality of wire routing slots are distributed around the seal and extend from the inside to its edge. The wire is inserted into the inside of the connector plug A or the connector plug B through the inside of the wire routing slot. The plurality of extended wools correspond to the plurality of wire routing slots respectively. When the seal is inserted into the inside of the connector plug A or the connector plug B and the sealing cotton pad is compressed and deformed, the extended wool fills into the inside of the wire routing slot.

[0021] In a possible implementation, the seal includes a plug head. One end of the plug head is integrally formed with a plug cover. The plug head is inserted into one end of the connector plug A or the connector plug B away from the mutual docking point. The surface of the plug cover close to the plug head is attached to the end face of the connector plug A or the connector plug B.

[0022] In a possible implementation, inclined surfaces are machined on the surfaces of the connector plug A and the connector plug B away from the mutual docking point. The connector plug A and the connector plug B both reserve a gap with the surface of the seal through the inclined surface.

[0023] In a possible implementation, sealing plates A are provided inside the two receiving strip grooves on the connector plug A, and sealing plates B are provided inside the two receiving strip grooves on the connector plug B. Three positioning strip grooves A are machined on the surface of the sealing plate B facing the inside of the connector plug B and the surface of the sealing plate A facing the inside of the connector plug A; the three positioning strip grooves A are respectively located at two corners and the center of the sealing plate A or the sealing plate B, and the three positioning strip grooves A are respectively aligned with the three positioning strip grooves B, supporting the two sliding strips B to slide inside the positioning strip grooves A at the two corners, while the sliding strip A slides inside the positioning strip groove A at the center.

[0024] In a possible implementation, limiting post strips are integrally formed on both sides of the sealing plate A and the sealing plate B, and grooves adapted to the limiting post strips are machined on both inner walls of the receiving strip groove, supporting the sealing plate A or the sealing plate B to be inserted into the inside of the receiving strip groove.

[0025] In a possible implementation, limiting rib strips are integrally formed on the surfaces of one ends of the connector plug A and the connector plug B, and matching rib strips are integrally formed on the surfaces of one ends of the sealing plate A facing away from the inside of the connector plug A and the sealing plate B facing away from the inside of the connector plug B; after the sealing plate B is inserted into the receiving strip groove on the connector plug B and the sealing plate A is inserted into the receiving strip groove on the connector plug A, the matching rib strips and the limiting rib strips are aligned.

[0026] The beneficial effects of this application are as follows:

[0027] First, in this solution, by pressing one end of the seal into the inside of the connector plug A or the connector plug B, the plug on one side of the plug cover is inserted into the inside of the connector plug A or the connector plug B. When the plug passes through the inside of the sealing cotton pad, the extending cotton is received inside the wire groove opening, and the sealing cotton pad can expand around and fill the space between the seal and the connector plug A or between the seal and the connector plug B, while the extending cotton fills the inside of the wire groove opening, eliminating the gaps between the wire and the inner wall of the connector plug A, the wire groove opening or the connector plug B, the wire groove opening inner wall, so as to achieve the effect of separating the inside of the connector plug A, the connector plug B from the external environment, which can play the role of isolating dust, water droplets and preventing electric shock, is easy to operate, and the sealing cotton pad is not easily damaged and is conducive to replacement;

[0028] Second, in this solution, by means of the inclined surfaces at one ends of the connector plug A and the connector plug B, a gap can be formed between the surface of the plug cover and the end face of the connector plug A or the connector plug B, which provides convenience for controlling the removal of the seal from the inside of the connector plug A or the connector plug B when the seal is inserted into the inside of the connector plug A or the connector plug B.

[0029] Thirdly, in this solution, the connector plug A and the connector plug B are inserted into each other in opposite directions. One end of the connector plug B presses on the push plate B at one end of the slide bar A on the connector plug A, and one end of the connector plug A presses on the push plate A at one end of the slide bar A on the connector plug B. The two gears are driven by the slide bar A to rotate around the corresponding support shaft columns, so as to pull the slide bar B in the reverse direction by means of the rack B, facilitating the hook to be pulled into the interior of the connector plug A through the support bar between the upper and lower slide bars B. Finally, the seal is inserted into the interior of one end of the connector plug B. The connection between the two seals and the connector plug A and the connector plug B can be completed through the docking of the connector plug A and the connector plug B; at the same time, the docking situation of the connector plug A and the connector plug B can be judged by referring to the connection situation between the seal and the connector plug A and the connection situation between the seal and the connector plug B; vice versa.

Detailed implementation mode

[0040] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0041] Embodiment 1:

[0042] This embodiment introduces the specific structure of a connector with excellent insulation performance. Specifically, refer to Figures 1-9 As shown, it includes a connector plug A1, a connector plug B2 inserted into one end of the connector plug A1, two seals 7 (respectively arranged at the ends of the connector plug A1 and the connector plug B2 away from the mutual docking point), and two sealing cotton pads 9 (respectively embedded at the ends of the connector plug A1 and the connector plug B2 away from the mutual docking point). The top and bottom of the connector plug A1 and the connector plug B2 are both provided with a co-directional transmission structure. The co-directional transmission structure includes a slide bar A12. Rack A14 is processed on both sides of the slide bar A12. One side of each of the two racks A14 is meshed and connected with a gear 19. A support shaft column 20 is arranged inside the gear 19. One side of the gear 19 is meshed and connected with a rack B17. Slide bar B18 is processed on one side of the rack B17. A support strip 23 is arranged between one ends of the upper and lower two slide bars B18 of the connector plug A1 or the connector plug B2. Shaft rods 22 are processed at both ends of the support strip 23; Hooks 25 are processed at the four corners of one end of the seal 7;

[0043] Among them, by hooking the hooks 25 on both sides of the seal 7 from the center to the outside of the two support bars 23, when the control connector plug A1 and the connector plug B2 are inserted oppositely, the slide bar A12 drives the two racks A14 to move to one side of the seal 7. With the help of the two gears 19 and the rack B17 respectively supported by the two support shafts 20, the slide bar B18 can be pulled to drive the hook 25 into the interior of one end of the income connector plug B2 or the connector plug A1, so that one end of the seal 7 is plugged into the interior of the connector plug A1 or the connector plug B2. Thus, the support co-directional transmission structure drives the two seals 7 to be respectively plugged into one end of the connector plug A1 and the connector plug B2 away from the mutual docking point, expanding the sealing cotton pad 9 around and filling it between the seal 7 and the connector plug B2, or between the seal 7 and the connector plug A1;

[0044] Secondly, in order to enable the connector plug A1 to control the seal 7 to be plugged into one end of the connector plug A1 through the co-directional transmission structure when the connector plug A1 and the connector plug B2 are inserted oppositely, as Figure 3 , Figure 4 and Figure 6 shown, receiving strip grooves 11 are processed on both the top and bottom surfaces of the connector plug A1 and the connector plug B2. Three positioning strip grooves B26 are processed on the bottom inner wall of the receiving strip groove 11. Limit strip grooves 15 are processed inside both ends of the top and bottom of the connector plug A1. One end of the slide bar A12 is processed with a push plate A13. By arranging the three positioning strip grooves B26 in parallel, the inside of the limit strip groove 15 is connected to the inside of the central positioning strip groove B26. When the push plate A13 extends into the interior of the connector plug A1 through the limit strip groove 15, when the connector plug B2 is inserted into the interior of the connector plug A1, the push plate A13 can be pushed to move inside the connector plug A1 by one end of the connector plug B2;

[0045] At the same time, by slidingly connecting the two slide bars B18 inside the positioning strip grooves B26 on both sides, and the slide bar A12 is slidingly connected inside the central positioning strip groove B26. During the process of the push plate A13 being pressed, the two gears 19 can be driven to rotate around the corresponding support shafts 20 by the racks A14 on both sides of the slide bar A12, so as to pull the slide bar B18 in the reverse direction with the help of the rack B17, facilitating pulling the hook 25 into the interior of the connector plug A1 by means of the support bar 23 between the upper and lower two slide bars B18, and finally enabling the seal 7 to be plugged into the interior of one end of the connector plug A1;

[0046] Furthermore, in order to enable the connector plug B2 to control the seal 7 to be plugged into one end of the connector plug B2 through the co-directional transmission structure when the connector plug A1 and the connector plug B2 are inserted oppositely, as Figures 4-7As shown, the storage slot 11 is also machined to the top and bottom of the center of the connector plug B2, and the limit slot 15 is also machined to the top and bottom centers of the connector plug B2. One end of the slide bars A12 at the top and bottom of the connector plug B2 is machined with a push plate B21. The surfaces of the two slide bars A12 facing each other are machined with a slide plate 27. By sliding the two slide bars B18 inside the positioning slots B26 on both sides, the slide bar A12 is slidably connected inside the positioning slot B26 at the center, and the slide plate 27 is slidably connected inside the limit slot 15. When the connector plug A1 is inserted into one end of the connector plug B2, one end of the connector plug A1 can be abutted against the push plate B21 to push the slide plate 27 to slide inside the limit slot 15, and the slide bar A12 drives the two racks A14 to retract into the connector plug A1;

[0047] At the same time, when the slide bar A12 drives the two racks A14 to retract into the connector plug A1, the slide bar A12 drives the two gears 19 to rotate around the corresponding support shafts 20 to pull the slide bar B18 in the reverse direction by means of the rack B17, so as to facilitate pulling the hook 25 to retract into the connector plug A1 by means of the support bar 23 between the upper and lower slide bars B18, and finally insert the seal 7 into one end of the connector plug B2;

[0048] As Figure 1 and Figure 2 shown, a plurality of wire grooves 8 are machined inside the seal 7, and a plurality of extended cotton 24 are integrally formed on the inner wall of the sealing cotton pad 9;

[0049] Among them, by arranging a plurality of wire grooves 8 around the seal 7 and extending from the inside to its edge, when the terminals on the wire are inserted into the connector plug A1 or the connector plug B2, the wire is inserted into the connector plug A1 or the connector plug B2 through the inside of the wire groove 8. By making a plurality of extended cotton 24 correspond to a plurality of wire grooves 8 respectively, when the connector plug A1 and the connector plug B2 are inserted opposite to each other, the sealing cotton pad 9 can be expanded outward when the seal 7 is inserted into the connector plug A1 or the connector plug B2, so that the extended cotton 24 fills the inside of the wire groove 8, thereby achieving the effect of isolating the connector plug A1 and the connector plug B2 from the external environment (having a good effect in blocking dust, water droplets and preventing electric shock).

[0050] Embodiment 2:

[0051] This embodiment introduces the specific structure of a connector seal 7 with excellent insulation performance in combination with Embodiment 1. Specifically, refer to Figure 1 、 Figure 2 and Figure 9 shown, including a plug head 702, and a plug cover 701 is integrally formed at one end of the plug head 702;

[0052] Among them, by inserting the plug 702 into one end of the connector plug A1 or the connector plug B2 away from the butt joint point, and making the surface of the side of the plug cover 701 close to the plug 702 fit with the end face of the connector plug A1 or the connector plug B2, the state of the opposite plugging of the connector plug A1 and the connector plug B2 can be judged by means of the situation between the plug cover 701 and the connector plug A1, the plug 702 and the end face of the connector plug B2. At the same time, the connection conditions of the seal 7 with the connector plug A1 and the seal 7 with the connector plug B2 can also be controlled by the situation of the opposite plugging of the connector plug A1 and the connector plug B2;

[0053] Secondly, in order to facilitate the removal of the seal 7 from the inside of the connector plug A1 or the connector plug B2, as Figure 9 shown, the surfaces of one ends of the connector plug A1 and the connector plug B2 away from the butt joint point are both machined with inclined surfaces. By making the connector plug A1 and the connector plug B2 both keep a gap with the surface of the seal 7 by means of the inclined surfaces, when it is necessary to remove the seal 7 from the inside of the connector plug A1 or the connector plug B2, sufficient support points can be provided.

[0054] Embodiment 3:

[0055] This embodiment introduces the specific structures of a connector plug A1 and a connector plug B2 with excellent insulation performance in combination with Embodiment 1 and Embodiment 2. Specifically, referring to Figures 1-3 shown, it includes a connector plug A1. Sealing plates A5 are arranged inside the two receiving strip grooves 11 on the connector plug A1, and sealing plates B6 are arranged inside the two receiving strip grooves 11 on the connector plug B2. Three positioning strip grooves A16 are machined on the surface of the sealing plate B6 facing the inside of the connector plug B2 and the surface of the sealing plate A5 facing the inside of the connector plug A1;

[0056] Among them, by making the three positioning strip grooves A16 be located at the two corners and the center of the sealing plate A5 or the sealing plate B6 respectively and be directly opposite to the three positioning strip grooves B26, when the sealing plate A5 is inserted into the receiving strip groove 11 on the connector plug A1 and the sealing plate B6 is inserted into the receiving strip groove 11 on the connector plug B2, two sliding strips B18 can be supported to slide inside the positioning strip grooves A16 at the two corners, and the sliding strip A12 slides inside the positioning strip groove A16 at the center, and the synchronous transmission structure is encapsulated into the inside of the connector plug A1 or the connector plug B2 to ensure the beautiful appearance of the connector plug A1 and the connector plug B2;

[0057] Secondly, in order to enable the sealing plate A5 to move only along the direction of the butt joint of the connector plug B2 and the connector plug A1 inside the connector plug A1 and the sealing plate B6 to move only along the direction of the butt joint of the connector plug B2 and the connector plug A1 inside the connector plug B2, asFigure 2 and Figure 3 As shown in Figure 3 , both sides of the sealing plate A5 and the sealing plate B6 are integrally formed with limiting column strips 10. By processing grooves adapted to the limiting column strips 10 on both inner walls of the storage strip groove 11, the sealing plate A5 or the sealing plate B6 can be supported and inserted into the interior of the storage strip groove 11, and the movement of the sealing plate A5 can be restricted to only the direction in which the connector plug A1 and the connector plug B2 are butted by means of the cooperation between the limiting column strips 10 and the grooves;

[0058] Furthermore, in order to facilitate the control of the butting of the connector plug A1 and the connector plug B2 and provide convenience for the insertion of the sealing plate A5 into the connector plug A1 and the insertion of the sealing plate B6 into the connector plug B2, as Figure 1 and Figure 2 shown, both ends of the connector plug A1 and the connector plug B2 are integrally formed with limiting rib strips 3 on the surface. The surfaces of one end of the sealing plate A5 facing away from the interior of the connector plug A1 and one end of the sealing plate B6 facing away from the interior of the connector plug B2 are integrally formed with matching rib strips 4. When the sealing plate B6 is inserted into the interior of the storage strip groove 11 on the connector plug B2 and the sealing plate A5 is inserted into the interior of the storage strip groove 11 on the connector plug A1, the matching rib strips 4 and the limiting rib strips 3 can be aligned to ensure that there are protrusions on the surfaces of both the connector plug A1 and the connector plug B2, which is beneficial to actual control.

[0059] Specifically, when using this connector with excellent insulation performance to assemble wires:

[0060] First, insert one end of the seal 7 into the interior of the connector plug A1 or the connector plug B2, so that the four hooks 25 at the four corners of the seal 7 are combined in pairs and deformed towards the center under the influence of the hooked parts. When the hooked parts of the hooks 25 cross the support strip 23, the hooks 25 are reset and straightened to hook on the support strip 23;

[0061] Then, insert the wire into the interior of the connector plug A1 or the connector plug B2 through the interior of the wire routing slot 8. When the terminals on the wire are inserted into and fixed in the connector plug A1 or the connector plug B2, the wire passes through the inner side of the sealing cotton pad 9;

[0062] Next, insert the seal 7 into the interior of the connector plug A1 or the connector plug B2 in two ways:

[0063] First, the connector plug A1 and the connector plug B2 are used separately. Press the plug cover 701 on the seal 7 so that the plug head 702 on one side of the plug cover 701 is inserted into the interior of the connector plug A1 or the connector plug B2. When the plug head 702 passes through the inner side of the sealing cotton pad 9, since the multiple wire grooves 8 correspond to the multiple extended cottons 24, the extended cottons 24 are received inside the wire grooves 8. When the surface of the plug cover 701 fits against the end face of the connector plug A1 or the connector plug B2, the sealing cotton pad 9 expands around and fills the space between the seal 7 and the connector plug A1 or between the seal 7 and the connector plug B2, while the extended cottons 24 fill the interior of the wire grooves 8, eliminating the gaps between the wire and the inner wall of the connector plug A1, the inner wall of the wire groove 8, or the connector plug B2, the inner wall of the wire groove 8, and achieving the effect of isolating the interior of the connector plug A1 and the connector plug B2 from the external environment;

[0064] Second, the connector plug A1 and the connector plug B2 are used in combination. The connector plug A1 and the connector plug B2 are inserted into each other in opposite directions. One end of the connector plug B2 presses on the push plate B21 at one end of the slide bar A12 on the connector plug A1, and one end of the connector plug A1 presses on the push plate A13 at one end of the slide bar A12 on the connector plug B2.
