Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to a bent through-hole connector. Background Technology

[0002] Traditional radially sealed connectors rely primarily on a sealing ring mounted on the connector housing, which is then fixed to the housing by its increased elasticity. Currently, there are two existing solutions: one is a through-hole connector, such as the one with patent publication number CN221305087U, where the outer sealing ring (70) is fitted onto the outer wall of the mounting hole (11); the other is a screw-type connector with terminal fixing function, such as the one with patent publication number CN215869907U, where an opening is provided on the housing, and screws for connecting terminals are inserted through this opening before the top cover is fastened and then secured with screws.

[0003] In applications requiring high sealing, significant compression is necessary. In such cases, a sealing ring relying solely on elastic fixation may buckle outwards when the connector is inserted into the cavity, preventing installation or causing seal failure. Traditional non-90° screw-type connectors, due to structural limitations, typically incorporate a fastening bolt and a window for disassembling the mounting plate at the adapter location. This window adds an extra layer of sealing, increasing both the number of components and the risk of seal failure. Therefore, this invention provides a bent-hole connector that addresses these issues. Utility Model Content

[0004] This utility model provides a bent through-hole connector. By adding radial and axial limiting structures to the sealing ring, it can effectively prevent the sealing ring from turning outward during the connector installation process, thus affecting the connector performance. By eliminating the skylight on the outer shell, one sealing structure is reduced, and the front and rear mounting plates can be detached. This not only reduces the number of assembly parts but also reduces the risk of seal failure. In summary, it solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a bent through-hole connector, comprising a mating copper busbar, a front mounting plate, a sealing ring, a housing, adapter fastening bolts, an adapter copper busbar, a rear mounting plate, and a tail accessory. The mating copper busbar is fixedly connected to the front mounting plate, which is mounted on one end of the housing and secured by multiple adapter fastening bolts. The adapter copper busbar is threaded with a nut that mates with it, and the adapter fastening bolts are threaded with nuts that mate with them. The sealing ring is nested on the front mounting plate and located between the front mounting plate and the housing. The adapter copper busbar, the rear mounting plate, and the tail accessory are all mounted on the other end of the housing.

[0007] Furthermore, the front mounting plate is provided with a first spring buckle and a first hanging platform, and the front mounting plate is provided with a number of square holes and round holes.

[0008] Furthermore, the sealing ring is provided with a number of protrusions, and the outer shell is provided with a number of grooves on the side near the sealing ring. The number of grooves is the same as the number of protrusions, the width is equal, and the center of each groove corresponds one-to-one with the center of each protrusion.

[0009] Furthermore, the outer casing is provided with a slope and a second mounting platform on the side near the sealing ring.

[0010] Furthermore, a second spring-loaded latch is provided on the rear mounting plate.

[0011] The present invention has the following advantages over the prior art:

[0012] (1) When using the bent through-hole connector of this utility model, the addition of radial and axial limiting structures on the sealing ring can effectively prevent the sealing ring from turning outward during the process of the connector being installed into the cavity, thus affecting the performance of the connector.

[0013] (2) When using the bent through-hole connector of this utility model, the skylight on the outer shell is eliminated, reducing one sealing structure and realizing the function of detachable front and rear mounting plates. This not only reduces the number of assembly parts, but also reduces the risk of seal failure.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Please see Figure 1-3 As shown, this utility model discloses a bent through-hole connector, including a mating copper busbar 1, a front mounting plate 2, a sealing ring 3, a housing 4, adapter fastening bolts 5, an adapter copper busbar 6, a rear mounting plate 7, and a tail accessory 8. The tail accessory 8 includes sealing and shielding structural components. The mating copper busbar 1 is fixedly connected to the front mounting plate 2, which is mounted on one end of the housing 4 and fixed by multiple adapter fastening bolts 5. The adapter copper busbar 6 is threaded with a nut 61 that mates with it. The sealing ring 3 is nested on the front mounting plate 2 and located between the front mounting plate 2 and the housing 4. The adapter copper busbar 6, the rear mounting plate 7, and the tail accessory 8 are all mounted on the other end of the housing 4.

[0024] The front mounting plate 2 is provided with a first spring buckle 21 and a first mounting platform 22, and has several square holes 23 and round holes 24. After the adapter copper busbar 6 is installed into the rear mounting plate 7, the adapter fastening bolt 5 is screwed into the nut 61 on the adapter copper busbar 6 through the round hole 24 on the front mounting plate 2 to realize the non-90° bending transition of the component-to-component copper busbar 1 and the adapter copper busbar 6. When disassembly is required, the adapter fastening bolt 5 is removed, and the positioning of the first spring buckle 21 is released through the square hole 23 on the front mounting plate 2 so that the front mounting plate 2 can be removed. Then the rear mounting plate 7 can be removed from the outer shell 4 to complete the disassembly. At this time, there is no skylight on the outer shell 4 at the transition position, thus reducing one sealing structure.

[0025] The sealing ring 3 has several protrusions 31, and the outer shell 4 has several grooves 41 on the side near the sealing ring 3. The number of grooves 41 is the same as the number of protrusions 31, and the width is equal. The center of each groove 41 corresponds to the center of each protrusion 31. When the mounting plate 2 is installed at one end of the outer shell 4, each protrusion 31 can be aligned and inserted into the corresponding groove 41. At this time, the mutual cooperation between the protrusions 31 and the grooves 41 can play a limiting role to prevent the position of the sealing ring 3 from shifting.

[0026] The outer casing 4 is provided with a slope 42 and a second mounting platform 43 on the side near the sealing ring 3. The slope 42 can restrict the end face of the sealing ring 3, thereby preventing the sealing ring 3 from moving radially or turning outward. After the front mounting plate 2 is installed into the outer casing 4, the first spring buckle 21 on the front mounting plate 2 will be hooked on the second mounting platform 43 on the outer casing 4 to play a positioning role.

[0027] The rear mounting plate 7 is provided with a second spring clip 71. When the rear mounting plate 7 is installed into the outer shell 4, the second spring clip 71 on the rear mounting plate 7 will hang on the first mounting platform 22 on the front mounting plate 2 to play a positioning role.

[0028] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0029] The working principle of this utility model is as follows:

[0030] In use, this utility model adds radial and axial limiting structures to the sealing ring 3 to prevent the sealing ring 3 from flipping outward during the connector installation process; a detachable second mounting plate 43 is provided on the front mounting plate 2 to be assembled and fixed with the outer shell 4, and a first mounting plate 22 is provided on the rear mounting plate 7 to hang on the front mounting plate 2. The rear mounting plate 7 can also be removed after the front mounting plate 2 is removed; the mounting holes for the adapter bolts are set on the front mounting plate 2, eliminating the skylight on the outer shell 4, thereby reducing one sealing structure, which not only reduces the number of assembly parts, but also reduces the risk of seal failure.
