Description

Technical Field

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

[0002] A wiring harness is the overall set of equipment that provides services to a specific group of load sources, such as relay lines, switching devices, and control systems. Based on their structure, wiring harnesses are classified into full-utilization wiring harnesses, partial-utilization wiring harnesses, and link systems. Based on their service methods, wiring harnesses are classified into loss-controlled wiring harnesses and standby-controlled wiring harnesses (see random service system). Based on the number of load sources served, wiring harnesses are classified into unlimited-load-source wiring harnesses and limited-load-source wiring harnesses.

[0003] In telecommunications systems, equipment used directly for inter-user communication often employs a full-utilization link system with unlimited load loss, while equipment used to control the connection process of communication equipment often employs a full-utilization system with unlimited load waiting. When the number of load sources is not large relative to the cable capacity, a full-utilization system or a partial-utilization system with limited load sources is generally used.

[0004] To make wiring harnesses usable in various devices and systems, terminals are often crimped onto each end of the harness and then inserted into a wiring connector to create connections between different harnesses and between harnesses and devices. Connectors generally refer to electrical connectors, bridging the gaps within a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0005] Patent document No. CN214625473U discloses a connector with excellent insulation performance. The connectors are provided at both ends of the body. A set of glass rings are fixedly mounted on the lower end of each set of connectors through a base. The glass rings have excellent insulation performance. The glass rings are designed to be different colors, so that the glass rings on the upper and lower sets of corresponding connectors are the same color, which facilitates workers to organize the wiring. At the same time, a rubber ring is provided on the connector at the lower end of the connector. The rubber ring also has excellent insulation performance, further improving the insulation performance of the utility model.

[0006] The patent document with announcement number CN214625473U is a kind of easy-to-assemble terminal wiring harness connector. The insulating sheath is set to make the insulation effect of the connector better and the safety performance of the connector stronger. When in use, the first sheath passes through the installation groove, and the first sheath is locked and adjusted by a thread inside the connecting sleeve. The opening of the first through-groove facilitates the installation of the plug, and the setting of the mounting sleeve facilitates the installation 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 opening of the first circular groove and the second circular groove facilitates the installation of the second wiring harness and the first wiring harness. The setting of the first limiting disc plays a certain limiting role on the plug, and the setting of the second limiting disc plays a certain limiting role on the plug spring. The overall insulating sheath is made of insulating plastic, and the insulation effect is good.

[0007] However, in the process of implementing the above technical solution, it was found that the above technical solution had the following technical problems:

[0008] The connector with excellent insulation performance (Announcement No.: CN214625473U) uses a rubber ring inside the insulating glass ring to make the connector located inside the rubber ring to improve the insulation performance of the connector. This method has better insulation performance, but in the actual operation, the rubber ring and the glass ring need to be installed exactly. The size deviation increases the difficulty of installation and takes a long time.

[0009] The easy-to-assemble terminal harness connector (Announcement No.: CN214625473U) uses an insulating sheath to fully cover the outside of the connector to ensure the insulation effect. However, during the removal of the harness terminal, the fully covered state can easily affect the operation, and the insulation layer can be easily damaged during this process. Summary of the Invention

[0010] In order to overcome the shortcomings of the prior art in that the insulation layers of connectors are either too tight or difficult to disassemble, the embodiments of the present application provide a connector with excellent insulation performance. By pressing one end of the sealing member into the interior of the connector plug A or the connector plug B, the plug on one side of the plug cover is inserted into the interior of the connector plug A or the connector plug B. When the plug passes through the inner side of the sealing cotton pad, the extended cotton is retracted inside the wiring groove. The sealing cotton pad can expand to fill between the sealing member and the connector plug A or the sealing member and the connector plug B, while the extended cotton fills the interior of the wiring groove, eliminating the gap between the wire and the connector plug A, the inner wall of the wiring groove, or the connector plug B, the inner wall of the wiring groove, thereby achieving the effect of isolating the interior of the connector plug A or the connector plug B from the external environment, isolating dust and water droplets and preventing electric shock, and is easy to operate. The sealing cotton pad is not easily damaged and is easy to replace.

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

The wires are plugged into the interior of the connector plug A or the connector plug B through the interior of the wiring slots. The multiple extended cottons correspond to the multiple wiring slots respectively, and when the seal is plugged into the interior of the connector plug A or the connector plug B to compress and deform the sealing cotton pad, the extended cotton fills the interior of the wiring slots.

[0021] In one possible implementation, the seal includes a plug, one end of which is integrally formed with a plug cover; the plug is plugged into an end of the connector plug A or the connector plug B away from the mutual docking point, and a side surface of the plug cover close to the plug is in contact with the end face of the connector plug A or the connector plug B.

[0022] In a possible implementation, the end surfaces of the connector plug A and the connector plug B away from the mutual docking point are both processed with a bevel, and the connector plug A and the connector plug B both maintain a gap with the surface of the seal through the bevel.

[0023] In one possible implementation, a sealing plate A is provided inside the two storage strip grooves on the connector plug A, and a sealing plate B is provided inside the two storage strip grooves on the connector plug B.

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

[0041] Example 1:

[0042] This embodiment introduces a specific structure of a connector with excellent insulation performance. Figures 1-9 As shown, it includes a connector plug A1, a connector plug B2 plugged into one end of the connector plug A1, two sealing members 7 (respectively arranged at one end of the connector plug A1 and the connector plug B2 away from the mutual docking point) and two sealing cotton pads 9 (respectively embedded in one end of the connector plug A1 and the connector plug B2 away from the mutual docking point). The top of the connector plug A1 and the connector plug B2 and the bottom of the connector plug A1 and the connector plug B2 are both provided with a same-direction transmission structure, and the same-direction transmission structure includes a slide bar A 12. Racks A14 are machined on both sides of the slide bar A12. One side of each rack A14 is meshedly connected to a gear 19. A support shaft 20 is provided on the inner side of the gear 19. A rack B17 is meshedly connected to one side of the gear 19. A slide bar B18 is machined on one side of the rack B17. A support bar 23 is provided between one end of the upper and lower slide bars B18 of the connector plug A1 or connector plug B2. A shaft 22 is machined on both ends of the support bar 23. Hooks 25 are machined at the four corners of one end of the seal 7.

[0043] Among them, by making the hooks 25 located on both sides of the seal 7 hook from the center to the outside of the two support bars 23 on both sides, when the connector plug A1 and the connector plug B2 are controlled to be plugged in opposite directions, the slide bar A12 drives the two racks A14 to move to one side of the seal 7, and with the help of the two gears 19 and the rack B17 supported by the two support shafts 20 respectively, the slide bar B18 can pull the hook 25 into the interior of one end of the 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, thereby supporting the same-direction transmission structure to drive the two seals 7 to be plugged into the ends of the connector plug A1 and the connector plug B2 away from the mutual docking point, and expand the sealing cotton pad 9 to the surroundings to fill 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 be plugged into one end of the connector plug A1 by controlling the sealing member 7 through the same direction transmission structure when the connector plug A1 and the connector plug B2 are oppositely plugged, as shown in FIG. Figure 3 、 Figure 4 and Figure 6 As shown, the top and bottom surfaces of the connector plug A1 and the connector plug B2 are both machined with a storage groove 11, and the bottom inner wall of the storage groove 11 is machined with three positioning grooves B26. The interior of the top and bottom ends of the connector plug A1 is both machined with a limit groove 15, and one end of the slide bar A12 is machined with a push plate A13. By arranging the three positioning grooves B26 in parallel, the interior of the limit groove 15 is connected to the interior of the positioning groove B26 located in the center. When the push plate A13 extends into the interior of the connector plug A1 through the limit groove 15, when the connector plug B2 is plugged into the interior of the connector plug A1, the push plate A13 can be pushed by one end of the connector plug B2 to move inside the connector plug A1.

[0045] At the same time, by making the two slide bars B18 slidably connected to the inside of the positioning bar grooves B26 located on both sides, and the slide bar A12 slidably connected to the inside of the positioning bar groove B26 located in the center, when the push plate A13 is pressed, the racks A14 on both sides of the slide bar A12 can drive the two gears 19 to rotate around the corresponding support shafts 20, so as to pull the slide bar B18 in the opposite direction with the help of the racks B17, so that the hook 25 can be pulled into the interior of the connector plug A1 with the help of the support bar 23 between the upper and lower slide bars B18, and finally the seal 7 can be inserted into the interior of one end of the connector plug A1;

[0046] Furthermore, in order to enable the connector plug B2 to be plugged into one end of the connector plug B2 by controlling the sealing member 7 through the same direction transmission structure when the connector plug A1 and the connector plug B2 are oppositely plugged, as shown in FIG. Figures 4 to 7As shown, the storage groove 11 is also processed to the top and bottom of the center of the connector plug B2, and the limiting groove 15 is also processed to the center of the top and bottom of the connector plug B2. One end of the slider A12 at the top and bottom of the connector plug B2 is processed with a push plate B21, and the surfaces facing the two sliders A12 are processed with a slide plate 27. By making the two sliders B18 slidably connected to the inside of the positioning grooves B26 located on both sides, the slider A12 is slidably connected to the inside of the positioning groove B26 located in the center, and the slide plate 27 is slidably connected to the inside of the limiting groove 15, when the connector plug A1 is inserted into the inside of one end of the connector plug B2, one end of the connector plug A1 can be used to press against the push plate B21 to push the slide plate 27 to slide inside the limiting groove 15, and the slider A12 drives the two racks A14 to be retracted into the inside of the connector plug A1;

[0047] At the same time, as the slide bar A12 drives the two racks A14 to retract into the interior of the connector plug A1, the slide bar A12 drives the two gears 19 to rotate about the corresponding support shafts 20, thereby pulling the slide bar B18 in the opposite direction with the help of the racks B17. This facilitates the hook 25 to be pulled into the interior of the connector plug A1 with the help of the support bar 23 between the upper and lower slide bars B18, and finally the seal 7 is inserted into the interior of one end of the connector plug B2.

[0048] like Figure 1 and Figure 2 As shown, the interior of the seal 7 is processed with a plurality of routing slots 8, and the inner wall of the sealing cotton pad 9 is integrally formed with a plurality of extension cottons 24;

[0049] Among them, by distributing multiple wiring slots 8 around the sealing member 7 and extending from the inside to its edge, when the terminal on the wire is plugged into the inside of the connector plug A1 or the connector plug B2, the wire is plugged into the inside of the wiring slot 8 through the inside of the wiring slot 8. By making multiple extension cottons 24 correspond to multiple wiring slots 8 respectively, when the connector plug A1 and the connector plug B2 are plugged in opposite directions, the sealing cotton pad 9 can be expanded outward with the help of the sealing member 7 being plugged into the inside of the connector plug A1 or the connector plug B2, so that the extension cotton 24 is filled into the inside of the wiring slot 8, thereby achieving the effect of isolating the connector plug A1 and the connector plug B2 from the external environment (it has a good effect in blocking dust, water droplets and preventing electric shock).

[0050] Example 2:

[0051] This embodiment introduces a specific structure of a connector seal 7 with excellent insulation performance in combination with embodiment 1. Figure 1 、 Figure 2 and Figure 9 As shown, it includes a plug head 702, one end of which is integrally formed with a plug cover 701;

[0052] Specifically, by inserting the plug head 702 into the end of the connector plug A1 or the connector plug B2 away from the mutual docking point, the surface of the plug cover 701 on the side close to the plug head 702 is in contact 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 determined by the conditions between the plug cover 701 and the connector plug A1, and between the plug head 702 and the end face of the connector plug B2. At the same time, the connection conditions of the sealing member 7 and the connector plug A1, and the connection conditions of the sealing member 7 and the connector plug B2 can be controlled by the conditions of the opposite plugging of the connector plug A1 and the connector plug B2.

[0053] Secondly, in order to facilitate the removal of the sealing member 7 from the interior of the connector plug A1 or the connector plug B2, as shown in FIG. Figure 9 As shown, the end surfaces of the connector plug A1 and the connector plug B2 away from the mutual docking point are both processed with a bevel. By making the connector plug A1 and the connector plug B2 maintain a gap with the surface of the seal 7 by means of the bevel, sufficient support points can be provided when the seal 7 needs to be removed from the inside of the connector plug A1 or the connector plug B2.

[0054] Example 3:

[0055] This embodiment introduces the specific structure of a connector plug A1 and a connector plug B2 with excellent insulation performance in combination with embodiment 1 and embodiment 2. Figures 1 to 3 As shown, it includes a connector plug A1, and the two storage grooves 11 on the connector plug A1 are each provided with a sealing plate A5, and the two storage grooves 11 on the connector plug B2 are each provided with a sealing plate B6, and the surface of the sealing plate B6 facing the interior of the connector plug B2 and the surface of the sealing plate A5 facing the interior of the connector plug A1 are both processed with three positioning grooves A16;

[0056] Among them, by arranging the three positioning strip grooves A16 at the two corners and the center of the sealing plate A5 or the sealing plate B6, and respectively facing the three positioning strip grooves B26, when the sealing plate A5 is inserted into the storage strip groove 11 on the connector plug A1, and the sealing plate B6 is inserted into the storage strip groove 11 on the connector plug B2, the two slide bars B18 can be supported to slide inside the positioning strip grooves A16 at the two corners, and the slide bar A12 can slide inside the positioning strip groove A16 at the center, and the synchronous transmission structure can be encapsulated inside the connector plug A1 or the connector plug B2, so as to ensure the beautiful appearance of the connector plug A1 and the connector plug B2;

[0057] Secondly, in order to make the sealing plate A5 inside the connector plug A1, the sealing plate B6 inside the connector plug B2 can only move along the direction in which the connector plug B2 and the connector plug A1 are connected, such as Figure 2 and Figure 3 As shown, both sides of the sealing plate A5 and the sealing plate B6 are integrally formed with limiting columns 10. By processing grooves that are compatible with the limiting columns 10 on the inner walls of the storage bar groove 11 on both sides, the sealing plate A5 or the sealing plate B6 can be supported and inserted into the interior of the storage bar groove 11. With the help of the cooperation between the limiting columns 10 and the grooves, the sealing plate A5 is restricted to move only in the direction of docking between the connector plug A1 and the connector plug B2;

[0058] Furthermore, in order to facilitate the connection between the control connector plug A1 and the connector plug B2, and to facilitate the plugging of the sealing plate A5 into the interior of the connector plug A1 and the plugging of the sealing plate B6 into the interior of the connector plug B2, as shown in FIG. Figure 1 and Figure 2 As shown, the surfaces of one end of the connector plug A1 and the connector plug B2 are both integrally formed with a limiting rib 3, and the surface of one end of the sealing plate A5 facing away from the interior of the connector plug A1, and the surface of one end of the sealing plate B6 facing away from the interior of the connector plug B2 are both integrally formed with a matching rib 4. When the sealing plate B6 is plugged into the storage strip groove 11 on the connector plug B2, and the sealing plate A5 is plugged into the storage strip groove 11 on the connector plug A1, the matching rib 4 and the limiting rib 3 can be aligned to ensure that the surfaces of the connector plug A1 and the connector plug B2 both have protrusions, which is conducive to actual control.

[0059] Specifically, when assembling wires using the connector with excellent insulation performance:

[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 toward the center under the influence of the hook portion. When the hook portion of the hook 25 crosses the support bar 23, the hook 25 returns to its original position and straightens to hook onto the support bar 23.

[0061] Then, insert the wire into the connector plug A1 or the connector plug B2 through the wiring slot 8, so that when the terminal on the wire is inserted into the connector plug A1 or the connector plug B2 and fixed, the wire passes through the inner side of the sealing cotton pad 9;

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

[0063] The first type is that the connector plug A1 and the connector plug B2 are used separately. The plug cover 701 on the sealing member 7 is pressed so that the plug head 702 on one side of the plug cover 701 is plugged into the inside 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, due to the correspondence between the multiple wiring slots 8 and the multiple extension cottons 24, the extension cotton 24 is retracted on the inner side of the wiring slot 8. When the surface of the plug cover 701 fits the end face of the connector plug A1 or the connector plug B2, the sealing cotton pad 9 expands to the surroundings and fills between the sealing member 7 and the connector plug A1 or the sealing member 7 and the connector plug B2, and the extension cotton 24 fills the inside of the wiring slot 8, eliminating the gap between the wire and the connector plug A1, the inner wall of the wiring slot 8 or the inner wall of the connector plug B2, the wiring slot 8, so as to achieve the effect of connecting the inside and the outside environment of the connector plug A1 or the connector plug B2.

[0064] The second type is to use the connector plug A1 and the connector plug B2 in combination, and the connector plug A1 and the connector plug B2 are plugged in oppositely, and one end of the connector plug B2 applies pressure to the push plate B21 at one end of the slider A12 on the connector plug A1, and one end of the connector plug A1 applies pressure to the push plate A13 at one end of the slider A12 on the connector plug B2, and the slider A12 drives the two gears 19 to rotate around the corresponding support shaft 20, so as to pull the slider B18 in the opposite direction with the help of the rack B17, so as to facilitate the hook 25 to be pulled into the interior of the connector plug A1 through the support bar 23 between the upper and lower sliders B18, and finally make the seal 7 inserted into the interior of one end of the connector plug B2, and finally make the extension cotton 24 fill the interior of the wiring groove 8, eliminating the gap between the wire and the connector plug A1, the inner wall of the wiring groove 8 or the connector plug B2, the inner wall of the wiring groove 8.

[0065] It is worth noting that when the plug 702 on the sealing member 7 is inserted into the interior of one end of the connector plug A1 or the connector plug B2, with the help of the inclined surface at one end of the connector plug A1 and the connector plug B2, a gap can be formed between the surface of the plug cover 701 and the end face of the connector plug A1 or the connector plug B2, which facilitates the control of the plug cover 701 to remove the plug 702 from the interior of the connector plug A1 or the connector plug B2.
