Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a dual-purpose integrated connector. Background Technology

[0002] With the development of the connector industry, various types of connectors have been widely used. However, these products still have some problems in practical use. For example, connectors on the market are usually designed for specific mating methods, such as through-hole or rotary threaded connections. This makes it difficult for female connectors to be compatible with different types of male connectors at the same time, resulting in limited application scenarios and increased production and maintenance costs.

[0003] A connector with publication number CN109119806B is described. This design includes a plug and a socket, where the plug comprises a first housing, a tail cap, and a first conductive terminal, and the socket comprises a second housing. This connector achieves adaptability to different wiring directions through the tail cap design. However, this design is only optimized for a single mating method (such as a through-hole type) and does not solve the problem of the female socket being incompatible with multiple mating methods. Furthermore, due to its complex structure, it has a high manufacturing cost and is not flexible enough in applications requiring frequent switching of mating methods.

[0004] A connector with publication number CN108988017B is described. This design includes a push-pull pin, a plug, and a socket, with the plug and socket connected by a locking hook and a locking ring. While this design provides anti-collision and anti-loosening functionality, its insertion method is limited to a single mode (such as a threaded connection), failing to meet users' needs for both direct-insertion and rotary threaded connections. Furthermore, the locking mechanism of this design occupies a significant amount of space, potentially limiting its practicality in compact devices.

[0005] The aforementioned problems indicate that traditional connectors currently on the market struggle to effectively address the compatibility requirements between different mating methods, especially in applications requiring flexible switching between mating methods. Therefore, this invention provides a dual-purpose integrated connector to overcome these shortcomings and offer a more flexible, efficient, and adaptable solution for changing environments.

[0006] The purpose of this invention is to provide a dual-purpose integrated connector to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dual-purpose integrated connector includes a female connector and a male connector. The female connector includes a housing, and a connecting inner sleeve is fixedly disposed on the inner wall of the housing. The outer diameter of the connecting inner sleeve matches the inner diameter of the housing. The inner wall of the connecting inner sleeve is provided with a helical thread, and the inner wall of the connecting inner sleeve is also provided with a plurality of insertion positioning grooves arranged in a ring array. The insertion positioning grooves extend radially outward from the inner wall of the connecting inner sleeve.

[0009] The specific structure of the insertion positioning groove is a rectangular groove extending outward along the inner wall of the connecting inner sleeve. The insertion positioning groove is evenly spaced along the circumferential direction of the connecting inner sleeve. The female connector also includes a core, which is fixedly disposed in the middle of the outer shell. One end of the core is fixedly connected to the inner wall of the outer shell, and the other end extends to the opening of the outer shell. The outer diameter of the core is smaller than the inner diameter of the connecting inner sleeve.

[0010] To further elaborate, the male connector is a rotary connector; the end of the rotary connector is provided with an external thread that matches the thread of the inner wall of the connecting inner sleeve.

[0011] To further elaborate, the male connector is a straight-in connector, and a positioning ring is sleeved and fixed at the end of the straight-in connector. The outer diameter of the positioning ring matches the inner diameter of the connecting inner sleeve. Multiple protrusions are arranged in a ring array on the outer side wall of the positioning ring. The shape and size of the protrusions match the insertion positioning groove of the connecting inner sleeve. The protrusions are arranged at equal intervals along the circumference of the positioning ring.

[0012] To further elaborate, after the protrusion on the positioning ring of the straight plug connector is aligned with the insertion positioning groove of the connecting inner sleeve, the straight plug connector is inserted into the connecting inner sleeve, and the protrusion is embedded in the insertion positioning groove, thereby realizing the positioning and fixing of the straight plug connector.

[0013] To further elaborate, the inner wall of the connecting sleeve is provided with a helical thread for adapting to the threaded connection of the rotary joint; the external thread of the rotary joint matches the internal thread of the connecting sleeve; the external thread of the rotary joint engages with the internal thread of the connecting sleeve to ensure tightness and anti-loosening performance of the connection.

[0014] To elaborate further, the outer shell has a cylindrical structure, and the inner diameter of the outer shell matches the outer diameter of the connecting inner sleeve, ensuring that the connecting inner sleeve is securely installed inside the outer shell.

[0015] To elaborate further, the outer diameter of the ferrule is smaller than the inner diameter of the connecting inner sleeve, ensuring sufficient insertion space for the straight connector and the rotary connector.

[0016] To elaborate further, the specific structure of the protrusion is a rectangular protrusion extending along the outer wall of the positioning ring.

[0017] To elaborate further, the inner wall of the connecting sleeve is also provided with multiple insertion positioning grooves in a ring array to fit the protrusions on the positioning ring of the direct insertion connector.

[0018] The structure and operating principle of this invention are as follows: The inner wall of the female connector's inner sleeve is provided with a helical thread for accommodating the threaded connection of a rotary connector. Simultaneously, the inner wall of the inner sleeve also has multiple insertion positioning grooves for accommodating the protrusions on the positioning ring of the straight-insertion connector, achieving positioning and fixation of the straight-insertion connector. When the straight-insertion connector is inserted into the female connector, the protrusions on the positioning ring engage with the insertion positioning grooves of the inner sleeve, achieving accurate positioning and fixation of the straight-insertion connector. When the rotary connector is rotated and inserted into the female connector, the external thread of the rotary connector engages with the internal thread of the inner sleeve, achieving a fixed connection of the rotary connector. Through this design, the female connector can simultaneously accommodate both straight-insertion and rotary threaded connection male connectors, improving the compatibility and flexibility of the connector.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. By setting a spiral thread and a plug positioning groove on the inner wall of the connecting sleeve, the female connector can be compatible with both straight-insertion and rotary threaded male connectors, improving the compatibility and flexibility of the connector.

[0021] 2. The protrusion on the positioning ring of the straight plug connector matches the insertion positioning groove of the inner sleeve, realizing accurate positioning and fixing of the straight plug connector, and improving the stability and reliability of the connection.

[0022] 3. The external thread of the rotary joint engages with the internal thread of the connecting inner sleeve, achieving a fixed connection of the rotary joint and ensuring the tightness and anti-loosening performance of the connection. Attached Figure Description

[0036] Insert 3: Insert 3 is fixedly disposed in the middle of housing 1, with one end fixedly connected to the inner wall of housing 1 and the other end extending to the outer side of housing 1. The outer diameter of insert 3 is smaller than the inner diameter of connecting inner sleeve 2 to ensure the insertion space of straight connector 7 and rotary connector 8.

[0037] The main structure of the male connector is as follows:

[0038] Straight-in connector 7: A positioning ring 5 is fitted and fixed at the end of the straight-in connector 7. The outer diameter of the positioning ring 5 matches the inner diameter of the connecting inner sleeve 2.

[0039] Rotary joint 8: The end of the rotary joint 8 is provided with an external thread 9 that matches the thread 9 on the inner wall of the connecting inner sleeve 2.

[0040] The specific structure connecting the inner sleeve 2 and the insertion positioning groove 4 is as follows:

[0041] Connecting inner sleeve 2: The inner wall of the connecting inner sleeve 2 is provided with a spiral thread 9 for accommodating the threaded connection of the rotary joint 8. Simultaneously, the inner wall of the connecting inner sleeve 2 is also provided with a plurality of insertion positioning grooves 4 arranged in a circular array. These insertion positioning grooves 4 are evenly spaced along the circumference of the connecting inner sleeve 2, with a total quantity of 3. Each insertion positioning groove 4 has a depth of 1.5mm, a width of 2.5mm, and a length of 7.5mm.

[0042] The specific structures of the positioning ring 5 and the protrusion 6 are as follows:

[0043] Positioning ring 5: Positioning ring 5 is fixedly installed at the end of the straight plug connector 7, and its outer diameter matches the inner diameter of the connecting inner sleeve 2.

[0044] Protrusion 6: Multiple protrusions 6 are arranged in a ring array on the outer wall of the positioning ring 5. The shape and size of these protrusions 6 match the insertion positioning groove 4 of the inner sleeve 2. There are 3 protrusions 6, which are evenly spaced along the circumference of the positioning ring 5. Each protrusion 6 has a length of 7.5 mm, a width of 2.5 mm, and a height of 1.5 mm.

[0045] The connection methods between the straight-insertion connector 7 and the rotary connector 8 and the female connector are as follows:

[0046] Connection of the straight connector 7: When the straight connector 7 is needed, the protrusion 6 on the positioning ring 5 of the straight connector 7 is aligned with the insertion positioning groove 4 of the connecting inner sleeve 2, and the straight connector 7 is inserted into the connecting inner sleeve 2. During the insertion process, the protrusion 6 is embedded in the insertion positioning groove 4, so as to achieve accurate positioning and fixation of the straight connector 7.

[0047] Connection of rotary joint 8: When rotary joint 8 is needed, the external thread 9 of rotary joint 8 is aligned with the internal thread 9 of connecting inner sleeve 2. By rotating, the external thread 9 of rotary joint 8 is engaged with the internal thread 9 of connecting inner sleeve 2, thereby achieving a fixed connection of rotary joint 8.

[0048] Specific application scenarios:

[0049] Assume the dual-purpose integrated connector of this invention is used in an industrial device that requires frequent connection and disconnection. The operator needs to select different connection methods in different situations. When quick connection and disconnection are required, the operator can choose to use the straight-insertion connector 7. After aligning the protrusion 6 on the positioning ring 5 of the straight-insertion connector 7 with the insertion positioning groove 4 of the connecting inner sleeve 2, the straight-insertion connector 7 is directly inserted into the connecting inner sleeve 2, and the protrusion 6 is embedded in the insertion positioning groove 4, achieving quick positioning and fixation. When a more stable connection is required, the operator can choose to use the rotary connector 8. Aligning the external thread 9 of the rotary connector 8 with the internal thread 9 of the connecting inner sleeve 2, and rotating it to engage the external thread 9 of the rotary connector 8 with the internal thread 9 of the connecting inner sleeve 2, a tighter and more stable connection is achieved.

[0050] The working principle is as follows:

[0051] The connection principle of the straight-plug connector 7: When the straight-plug connector 7 is inserted into the female connector, the protrusion 6 on the positioning ring 5 aligns with and embeds into the insertion positioning groove 4 of the inner sleeve 2. This structure ensures that the straight-plug connector 7 can be accurately positioned during insertion, preventing misalignment during the insertion process and improving the stability and reliability of the connection.

[0052] The connection principle of rotary joint 8: When rotary joint 8 is inserted into the female connector, the external thread 9 of rotary joint 8 engages with the internal thread 9 of connecting inner sleeve 2. Through rotation, the external thread 9 and internal thread 9 gradually tighten together, ultimately achieving a fixed connection of rotary joint 8. This threaded connection method ensures a tight connection and anti-loosening performance, making it particularly suitable for scenarios requiring long-term stable connections.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
