DETAILED DESCRIPTION

[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figures 1 to 5 As shown, the utility model provides a connector rubber core, including a rubber core component 1, a plug shell 2, a shielding cover 3 and a sealing member 4. Among them,

[0032] The rubber core assembly 1 includes a body 11, a rubber core shell 12 connected to the body 11, a first clamping portion 13 and a second clamping portion 14. The body 11 is used as a part for carrying the conductive terminal. The rubber core shell 12 is arranged around one end of the body 11. One end of the rubber core shell 12 and the body 11 are surrounded to form a first plug-in cavity 15. The other end of the core shell and the body 11 are surrounded to form a first plug-in slot 16 for receiving and fixing the corresponding part of the plug. The first clamping portion 13 is arranged in the first plug-in cavity 15, and the second clamping portion 14 is arranged in the first plug-in slot 16. The plug shell 2 has a second plug-in cavity 15 adapted to the first plug-in slot 16. The connecting cavity 21 and the third clamping portion 22 matched with the second clamping portion 14, the plug shell 2 is sleeved on the peripheral side of the rubber core component 1; the shielding cover 3 is arranged between the rubber core component 1 and the plug shell 2 to provide electromagnetic shielding, reduce external electromagnetic interference, and protect the pure transmission of the signal, and the shielding cover 3 has a metal spring 31 matched with the first clamping portion 13; the sealing member 4 is sleeved on the peripheral side of the shielding cover 3, and the two ends of the sealing member 4 are respectively against the bottom wall of the plug shell 2 and the second plug-in cavity 21 to ensure the sealing of the entire connection area, prevent dust, moisture and other pollutants from entering, and improve the environmental adaptability and reliability of the connector.

[0033] Based on the above structure, this embodiment reduces the use of additional fixing parts, simplifies the assembly steps, reduces the assembly error rate, and improves production efficiency through the clamping structure, such as the cooperation between the first clamping part 13 and the metal spring 31, and the cooperation between the second clamping part 14 and the third clamping part 22.

[0034] It should be noted that the first clamping portion 13 of the present embodiment is a clamping slot formed on the first plug-in slot 16, which is used to clamp the metal spring 31 of the shielding cover 3 to achieve the limiting effect. The first plug-in slot 16 is an annular racetrack groove to match the second plug-in cavity 21 and the shielding cover 3 structure. The third clamping portion 22 is a clamping slot formed on the second plug-in slot, and the second clamping portion 14 is a female buckle formed on the first plug-in slot 16.

[0035] It can be understood that the rubber core shell 12 in this embodiment can be a structure with a partition plate formed in the middle, so that when connected to the body 11, it can enclose the body 11 to form a first plug-in cavity 15 and a first plug-in slot 16, wherein the openings of the first plug-in cavity 15 and the first plug-in slot 16 face opposite directions. In addition, in some embodiments, the body 11 can also be formed with a first plug-in cavity 15, and the rubber core shell 12 and the body 11 can be enclosed to form a first plug-in slot 16.

[0036] Furthermore, the plug housing 2 includes a first housing 23 and a second housing 24 connected to the first housing 23. The first housing 23 provides basic physical support and external contours. The second housing 24 is enclosed around the first housing 23 and defines a second plug-in cavity 21 together with the first housing 23, which is used to receive and protect the shielding cover 3 and the body 11, increase structural strength and provide further protection. The outer wall of the first housing 23 has a third clamping portion 22, which is used to mechanically lock or position with the second clamping portion 14 to ensure the stability of the connection. The shielding cover 3 is arranged between the inner wall of the first housing 23 and the outer wall of the body 11. The rubber core housing 12 is sleeved around the first housing 23, and the second housing 24 is enclosed around the rubber core housing 12. This embodiment improves the mechanical strength and stability of the connector through the above structure, and increases protection through the structure of the multi-layer housing.

[0037] Read also Figure 7 The bottom wall of the first plug-in slot 16 is raised to form a plurality of raised portions 17, which are enclosed to form a snap-in position so as to accurately dock with another component during the connection process to achieve a more stable mechanical connection, wherein the snap-in position is arranged corresponding to the first snap-in portion 13, and the top of the first shell 23 has a lip position 231 adapted to the snap-in position. When the plug shell 2 is inserted into the first plug-in slot 16, the lip position 231 can be embedded in or cover the snap-in position, further reinforcing the connection from the outside to ensure the tightness and stability of the connection, and realizing a multiple locking mechanism, which not only enhances the physical stability of the plug shell 2, the rubber core assembly 1 and the shielding cover 3 during use, and prevents loosening or separation due to vibration, pulling and other factors, but also improves the safety and reliability of the connection, ensuring good electrical contact and stability for long-term use.

[0038] Furthermore, the plug housing 2 also includes a positioning portion 25 formed by the protrusion of the bottom wall of the second plug-in cavity 21, and the two ends of the seal 4 are respectively in contact with the positioning portion 25 and the plug housing 2. In this embodiment, through the above structure, when the plug housing 2 is inserted into the first plug-in slot 16, the seal 4 is compressed at both ends to form a tight sealing ring, so that the connectors produce a sealing effect when plugged in, effectively preventing moisture, dust and other contaminants from entering the connection area between the plug housing 2 and the body 11, improving the reliability and service life of the connector, and also enhancing the electrical safety performance, preventing safety hazards such as short circuits. At the same time, the presence of the positioning portion 25 makes the installation and sealing effect of the seal 4 more accurate, ensuring that each connection can meet the expected requirements.

[0039] See also Figure 5 The body 11 is recessed to form two terminal accommodating cavities 111 for accommodating terminals, so as to ensure that each terminal has an accurate position and stable support. The outer wall of the body 11 is provided with a reinforcing structure for supporting the terminal accommodating cavity 111 to provide additional mechanical support for the terminal accommodating cavity 111. The reinforcing structure is a cross-bone position. Of course, in some embodiments, it can also be a protrusion, a rib or other structure, as long as it can improve the structural strength and rigidity of the terminal accommodating cavity 111 to avoid deformation or damage of the terminal accommodating cavity 111 when the terminal is subjected to insertion force, extraction force or external mechanical vibration, to ensure the correct position and contact pressure of the terminal, thereby maintaining the long-term stability and reliability of the connector.

[0040] like Fig. 9 As shown, the shielding cover 3 includes a cover body 32, an outer ring 33 and a claw hook 34. The cover body 32 is connected to the outer ring 33. The cover body 32 is arranged on the side of the main body 11 to provide electromagnetic shielding to prevent external electromagnetic interference from affecting the signal transmission inside the connector. At the same time, it can also prevent the electromagnetic radiation generated by the internal circuit from causing interference to the outside world. The outer ring 33 is engaged with the terminal accommodating cavity 111 to provide additional mechanical support or auxiliary fixation.

[0041] In addition, a step structure 1111 is formed in the terminal accommodating cavity 111 for limiting the outer ring 33, ensuring that the outer ring 33 of the shielding cover 3 can be firmly engaged in a predetermined position, ensuring the position accuracy of the shielding cover 3 during installation, preventing the shielding cover 3 from shifting during assembly or use, and maintaining the maximum shielding effectiveness.

[0042] It should be noted that the claw hooks 34 in the embodiment are installed on the inner wall of the cover body 32 and located on both sides of the metal spring sheet 31. The first clamping portion 13 can avoid the claw hooks 34 of the shielding cover 3 to reduce the friction force of pushing the shielding cover 3 into the rubber core.

[0043] Furthermore, the outer ring 33 includes a connecting plate 331 and a plurality of bite portions 332. The connecting plate 331 is connected to the cover body 32. The connecting plate 331 is formed with two through holes corresponding to the terminal accommodating cavity 111. In order to ensure that the shielding cover 3 does not hinder the normal arrangement and electrical connection of the terminals during installation, while reducing the weight of the shielding cover 3, reducing costs and leaving space for specific electrical paths, the bite portion 332 is connected to the orifice of the through hole, which can effectively prevent the shielding cover 3 from rotating or falling off after installation.

[0044] This embodiment forms a stable mechanical snap-fit ​​structure by connecting the bite portion 332 with the opening of the through hole, which not only enhances the connection strength between the shielding cover 3 and the main body 11, but also improves the stability of the entire connector when dealing with mechanical stress (such as plug-in force, vibration), thereby protecting internal sensitive components from damage and extending service life.

[0045] Furthermore, a slope structure 1112 extending obliquely toward the bottom wall of the terminal accommodating cavity 111 is formed in the terminal accommodating cavity 111. The slope structure 1112 can serve as a guide path for the terminal to be inserted, so that the barbs on both sides of the terminal can slide into the rubber core more smoothly and more accurately into its predetermined position, thereby reducing the risk of plugging errors and damage. In addition, during the insertion process, the terminal installation position is limited, which improves the convenience of terminal installation, simplifies the assembly operation, reduces the dependence on the operator's skills, and improves production efficiency.

[0046] Furthermore, a guide boss 1113 for limiting the terminal is formed in the terminal accommodating cavity 111. During the terminal insertion process, the guide boss 1113 can serve as a physical guide to help the terminal align with the contact point or socket along the correct path. In addition, by contacting or surrounding a partial area of ​​the terminal, the terminal is prevented from rotating when pushed into the accommodating cavity, and the terminal is fixed and limited all around.

[0047] like Figure 8 As shown, the rubber core assembly 1 also includes a high-voltage interlocking terminal 18, which is connected to the body 11 and is located in the first plug-in cavity 15, so that the high-voltage interlocking function becomes a part of the connector structure. When the connector is correctly inserted and used, the high-voltage interlocking terminal 18 will also be connected to form a closed loop to confirm the safety of the connection state; in addition, the high-voltage interlocking terminal 18, the body 11 and the rubber core shell 12 are integrally formed, which improves the reliability and durability of the connector, reduces the risk of potential assembly errors and loose connections, and also simplifies the manufacturing process, reduces the number of molds required for production, and reduces costs.

[0048] The installation steps are as follows: the shielding cover 3 is inserted forward into the second plug-in cavity 21 until the metal spring 31 is fastened with the first clamping portion 13, and the seal 4 is installed to the lip position 231 of the plug shell 2; the body 11 is inserted into the first shell 23 along the lip position 231 of the plug shell 2, the tail end of the rubber core shell 12 contacts the seal 4, and the seal 4 moves inward, and there are two second clamping portions 14 on both sides of the inner wall of the rubber core shell 12 that cooperate with the third clamping portion 22 of the plug shell 2 to form a buckle fixation. At this time, the bottom surface of the seal 4 is in contact with the positioning portion 25, and the assembly is completed.

[0049] In summary, the embodiment of the utility model provides a connector rubber core, which reduces the use of additional fixing parts, simplifies the assembly steps, reduces the assembly error rate, and improves production efficiency through a clamping structure, such as the cooperation between the first clamping part 13 and the metal spring 31, and the cooperation between the second clamping part 14 and the third clamping part 22.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
