Description

Technical Field

[0001] This utility model relates to a novel sealed cable connector. Background Technology

[0002] In the field of cable connection, sealed cable joints are key components for connecting cables and conductive terminals. Their core function is to achieve a stable electrical connection between the cable and the conductive terminals, and to prevent external dust, moisture, corrosive media, etc. from entering the joint through a sealing structure, thus ensuring the insulation performance and service life of the connection.

[0003] Existing sealed cable connectors generally use independent fixing parts (such as bolts and clips) to fix the sealing block, while additional sealing parts (such as plugs and sealing caps) are required to seal the connection cavity. This structure has the problems of a large number of parts and a complex overall structure, which not only increases the production and assembly costs, but also requires separate operation of the fixing parts and sealing parts during subsequent maintenance, resulting in poor convenience. In view of this, this utility model proposes a new type of sealed cable connector to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel sealed cable connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel sealed cable connector, connected to a conductive terminal; comprising: T-shaped connecting housing; the T-shaped connecting housing is provided with a first connecting cavity and a second connecting cavity; the first connecting cavity is connected to a conductive terminal; A sealing block; the sealing block is assembled into the second connecting cavity and forms a sealing fit with the second connecting cavity; End cap; the end cap is detachably connected to the sealing block, and the end cap is connected to the T-shaped connecting housing to fix the sealing block in the second connecting cavity; The T-shaped connecting housing has a connecting outer wall surrounding the first connecting cavity, and the end cap is fitted onto the connecting outer wall and seals with it, so that the first connecting cavity forms a sealed space.

[0006] As an improvement to the above technical solution, the connecting outer wall is provided with a connecting external thread, and the connecting external thread is matched with the position of the first connecting cavity; The inner wall of the end cap is provided with an internal thread, which engages with the external thread to connect the end cap to the T-shaped connecting housing.

[0007] As an improvement to the above technical solution, a reinforcing block is provided inside the end cap, and a mounting screw is provided on the reinforcing block; The sealing block is provided with a mounting threaded hole, and the mounting screw is threadedly engaged with the mounting threaded hole.

[0010] As an improvement to the above technical solution, the reinforcing block is interference-fitted with the first connecting cavity.

[0011] As an improvement to the above technical solution, the sealing block is interference-fitted with the second connecting cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The end cap can be detachably connected to the sealing block to fix the sealing block in the second connecting cavity, and can also cooperate with the connecting outer wall of the T-shaped connecting shell to block the first connecting cavity. This realizes the reuse of two functions of a single end cap for fixing the sealing block and blocking the first connecting cavity.

Detailed Implementation

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: like Figure 1-5 As shown, this embodiment proposes a novel sealed cable connector, connected to conductive terminal 10; comprising: T-shaped connecting housing 20; the T-shaped connecting housing 20 is provided with a first connecting cavity 22 and a second connecting cavity 23; the first connecting cavity 22 is connected to the conductive terminal 10; Sealing block 30; the sealing block 30 is assembled into the second connecting cavity 23 and forms a sealing fit with the second connecting cavity 23; End cap 40; the end cap 40 is detachably connected to the sealing block 30, and the end cap 40 is connected to the T-shaped connecting housing 20 to fix the sealing block 30 in the second connecting cavity 23; The T-shaped connecting housing 20 is provided with a connecting outer wall 21 surrounding the first connecting cavity 22. The end cap 40 is sleeved on the connecting outer wall 21 and seals with the connecting outer wall 21, so that the first connecting cavity 22 forms a sealed space.

[0017] In this embodiment, when the T-shaped connecting housing 20 is used, the end cap 40 is removed from the connecting outer wall 21 and connected to the sealing block 30, so that the first connecting cavity 22 is opened. Then the first connecting cavity 22 is connected to the conductive terminal 10, and the electrical connection process of the T-shaped connecting housing 20 is completed. When the T-shaped connecting housing 20 is not in use, the end cap 40 is removed from the sealing block 30, and then the end cap 40 is fitted onto the connecting outer wall 21 to seal the first connecting cavity 22. The end cap 40 can be detachably connected to the sealing block 30 to fix the sealing block 30 in the second connecting cavity 23, and can also cooperate with the connecting outer wall 21 of the T-shaped connecting housing 20 to block the first connecting cavity 22. This realizes the reuse of the two functions of fixing the sealing block 30 and blocking the first connecting cavity 22 by a single end cap 40, without the need for additional independent fixing and blocking parts, which simplifies the overall structure of the connector and reduces production and assembly costs. By setting a first connecting cavity 22 and a second connecting cavity 23 in the T-shaped connecting housing 20, the first connecting cavity 22 is dedicated to electrical connection with the conductive terminal 10, and the second connecting cavity 23 is dedicated to assembling the sealing block 30. This achieves effective separation of conductive connection function and sealing assembly function, avoiding functional interference. At the same time, the integrated T-shaped connecting housing 20 structure simplifies the overall number of components and optimizes the spatial layout.

[0018] Specifically, the connecting outer wall 21 is provided with a connecting external thread 24, and the connecting external thread 24 is matched with the position of the first connecting cavity 22; The inner wall of the end cap 40 is provided with a connecting internal thread 41, which is threadedly engaged with the connecting external thread 24, so that the end cap 40 is connected to the T-shaped connecting housing 20.

[0019] In this embodiment, the external thread 24 on the connecting outer wall 21 and the internal thread 41 on the connecting inner wall of the end cap 40 form a threaded engagement, which enables the end cap 40 to be stably connected to the T-shaped connecting housing 20, effectively preventing the end cap 40 from loosening or falling off during use or idle sealing, and ensuring the stability of the connection structure. Since the external thread 24 matches the position of the first connecting cavity 22, the threaded connection allows the end cap 40 to fit tightly against the connecting outer wall 21, reducing the gap between them and thus improving the sealing effect of the first connecting cavity 22. At the same time, the positioning characteristics of the threaded connection ensure that the end cap 40 accurately corresponds to the position of the first connecting cavity 22, achieving accurate sealing of the first connecting cavity 22.

[0020] Specifically, a reinforcing block 42 is provided inside the end cap 40, and a mounting screw 43 is provided on the reinforcing block 42; The sealing block 30 is provided with a mounting threaded hole 31, and the mounting screw 43 is threadedly engaged with the mounting threaded hole 31.

[0021] In this embodiment, the mounting screw 43 on the reinforcing block 42 and the mounting threaded hole 31 on the sealing block 30 form a threaded engagement, which enables the end cover 40 and the sealing block 30 to be stably connected, effectively preventing relative displacement or separation between the two during assembly or use. At the same time, the threaded engagement structure facilitates disassembly and assembly operations as needed, providing convenience for subsequent maintenance, replacement of the sealing block 30 or adjustment of the end cover 40.

[0022] Specifically, the reinforcing block 42 is adapted to the internal cavity structure of the first connecting cavity 22, and the end cap 40 is connected to the T-shaped connecting housing 20, so that the reinforcing block 42 is sealed in the first connecting cavity 22.

[0023] In this embodiment, since the reinforcing block 42 is adapted to the internal structure of the first connecting cavity 22, when the end cap 40 is connected to the T-shaped connecting shell 20, the reinforcing block 42 can form a close-fitting seal with the inner wall of the first connecting cavity 22, effectively reducing the sealing gap, thereby preventing external dust, moisture, impurities and other substances from entering the interior of the first connecting cavity 22, ensuring the cleanliness of the first connecting cavity 22 and the performance stability of any connecting structures that may exist inside.

[0024] Specifically, the sealing block 30 is adapted to the internal cavity structure of the second connecting cavity 23, so that the sealing block 30 seals the second connecting cavity 23.

[0025] In this embodiment, the sealing block 30 is adapted to the inner cavity structure of the second connecting cavity 23. The two are well matched in shape and size. When the sealing block 30 is sealed, it can fit tightly against the inner wall of the second connecting cavity 23, effectively reducing the sealing gap, thereby reliably preventing external dust, moisture, impurities and other substances from entering the interior of the second connecting cavity 23, ensuring the cleanliness of its internal environment and the integrity of its structure.

[0026] Specifically, the reinforcing block 42 is interference-fitted with the first connecting cavity 22.

[0027] In this embodiment, the reinforcing block 42 and the first connecting cavity 22 are fitted with an interference fit. After assembly, a radial preload is formed between the two, which can completely eliminate the fit gap and effectively prevent external dust, water vapor, corrosive media and other substances from entering the interior of the first connecting cavity 22. This prevents the internal structure used to connect with the conductive terminal 10 from failing due to environmental erosion and greatly improves the sealing reliability.

[0028] Specifically, the sealing block 30 is interference-fitted with the second connecting cavity 23.

[0029] In this embodiment, the sealing block 30 and the second connecting cavity 23 are fitted with an interference fit. After assembly, a radial preload is formed between the two, which can completely eliminate the fit gap and effectively prevent external dust, water vapor, corrosive media and other substances from entering the interior of the second connecting cavity 23. This prevents the internal structure used to connect with the conductive terminal 10 from failing due to environmental erosion and greatly improves the sealing reliability.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
