Description

Technical Field

[0001] This utility model relates to the field of data connector technology, and more specifically, to a connector with a replaceable inner core. Background Technology

[0002] In existing technologies, the base is simply installed and fixed inside the outer casing. Different inner cores are compatible with different external connection devices. These inner cores typically have two-pin, three-pin, or four-pin connectors. Due to the large number of inner core models, different outer casings are required to accommodate them, resulting in high costs. Currently, the outer casings are not universally compatible, making it impossible to replace different inner cores during assembly. Furthermore, the installation between the outer casing and the inner core is cumbersome, leading to low production efficiency. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a connector with a replaceable inner core, comprising a housing, an inner core, and a bottom cover adapted to the inner core. The housing has a first opening and a second opening at its axial ends, and a first limiting part and a second limiting part are provided on the inner wall of the housing. After the inner core enters the housing through the first opening, it is limited and engaged with the first limiting part. After the bottom cover enters the housing through the second opening, it is limited and engaged with the second limiting part. The bottom cover and the second opening are fixed together by adhesive.

[0004] Optionally, the inner core includes an inner cylinder, one end of which is provided with a base, and the side wall of the base is provided with a first limiting opening, the first limiting part being located in the first limiting opening to prevent the inner core from rotating.

[0005] Optionally, the inner core further includes a plurality of pins, each pin having a protruding elastic connecting arm. The base has a plurality of first connecting holes adapted to the pins, and the bottom cover has a plurality of second connecting holes adapted to the pins. The connecting arm is capable of elastic deformation so that it can pass through the first connecting hole and the second connecting hole.

[0006] Optionally, the base is provided with an mounting groove, in which a sealing ring is installed, and the two axial ends of the sealing ring abut against the base and the bottom cover, respectively.

[0007] Optionally, the inner ring of the outer shell is provided with a limiting step, the limiting step including a first step, the first limiting part being disposed on the inner side wall of the first step, and the outer peripheral wall of the base abutting against the inner peripheral wall of the first step.

[0008] Optionally, the limiting step further includes a second step, the second limiting part is disposed at one end of the second step near the second opening, and the end of the bottom cover away from the second opening abuts against the second step.

[0009] Optionally, the second step and the mounting groove are radially aligned to form a mounting cavity, in which the sealing ring is accommodated.

[0010] Optionally, a second limiting opening is provided on the side wall of the bottom cover, and the second limiting part is located in the second limiting opening to prevent the bottom cover from rotating.

[0011] Optionally, the inner wall of the housing is provided with an L-shaped connecting groove for connecting with an external device. The external device is provided with a connecting block, which is axially inserted into the connecting groove and then rotated to fix it.

[0012] Optionally, the outer wall of the housing is provided with external threads for threaded connection with the external device.

[0013] Compared to existing technologies, the replaceable inner core connector in this invention restricts the rotation of the inner core through a first limiting part and restricts the rotation of the bottom cover through a second limiting part, preventing the inner core and bottom cover from rotating and becoming loose, making installation simpler and more reliable. By simply aligning the inner core with the first limiting part and the base with the second limiting part, the outer shell can be adapted to inner cores with different numbers of pins, achieving the effect of one model of shell adapting to multiple models of inner cores, thus reducing production costs.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] This utility model embodiment provides a connector with a replaceable inner core, combined with Figures 1 to 6 As shown, the device includes an outer shell 1, an inner core 2, and a bottom cover 4 adapted to the inner core 2. The outer shell 1 has a first opening 11 and a second opening 12 at its two axial ends. The inner wall of the outer shell 1 has a first limiting part 13 and a second limiting part 14. The inner core 2 enters the outer shell 1 through the first opening 11 and is limited and engaged with the first limiting part 13. The bottom cover 4 enters the outer shell 1 through the second opening 12 and is limited and engaged with the second limiting part 14. The bottom cover 4 and the second opening 12 are bonded and fixed together with glue 5.

[0024] like Figure 4 As shown, in this embodiment, both the outer shell 1 and the inner core 2 are cylindrical, and the bottom cover 4 is a circular plate. The first limiting part 13 restricts the rotation of the inner core 2, and the second limiting part 14 restricts the rotation of the bottom cover 4, preventing the inner core 2 and the bottom cover 4 from rotating and loosening. By bonding with glue 5, not only can the position of the bottom cover 4 be fixed axially, but the glue 5 also seals the second opening 12, which can achieve the effect of waterproofing and dustproofing.

[0025] Optionally, the inner core 2 includes an inner cylinder 21, one end of which is provided with a base 22, and the side wall of the base 22 is provided with a first limiting opening 23. The first limiting part 13 is limited in the first limiting opening 23 to prevent the inner core 2 from rotating.

[0026] like Figure 5 As shown, in this embodiment, the cross-sectional diameter of the base 22 is larger than the cross-sectional diameter of the inner cylinder 21. When installing the inner core 2, the first limiting port 23 is aligned with the first limiting part 13 and inserted, or the inner core 2 is directly inserted into the outer shell 1 and then rotated and pressed until the first limiting port 23 and the first limiting part 13 are inserted and fixed.

[0027] Optionally, the inner core 2 further includes a plurality of pins 3, each pin 3 having a protruding elastic connecting arm 31. The base 22 has a plurality of first connecting holes 24 adapted to the pins 3, and the bottom cover 4 has a plurality of second connecting holes 42 adapted to the pins 3. The connecting arm 31 can undergo elastic deformation so that the connecting arm 31 can pass through the first connecting hole 24 and the second connecting hole 42.

[0028] like Figures 1 to 3 As shown, glue 5 can penetrate into the second connecting hole 42 to axially fix the pin 3, and simultaneously axially fix the base 22 and the base 22. The pin 3 extends out of the outer shell 1 from the second opening 12 to connect to an external power socket. In this embodiment, there are four pins 3, and four first connecting holes 24 and four second connecting holes 42, which are axially aligned. During installation, the pin 3 can be first inserted into the first connecting hole 24 and then installed in the outer shell 1 together with the inner core 2. After aligning the second connecting hole 42 of the bottom cover 4 with the pin 3, it can be inserted from the second connecting hole 42. Alternatively, the inner cylinder 21 and the base 22 can be installed first, and then the pin 3 can be inserted from the first opening 11. These two installation methods reduce the limitations of the installation steps.

[0029] Optionally, the base 22 is provided with an mounting groove 25, in which a sealing ring 26 is installed, and the two axial ends of the sealing ring 26 abut against the base 22 and the bottom cover 4 respectively.

[0030] like Figure 3 As shown, in this embodiment, the sealing ring 26 serves to prevent dust and water from entering through the first opening 11 and flowing into the connection gap between the base 22 and the outer shell 1, thus preventing corrosion and damage to the bottom cover 4. Simultaneously, because the sealing ring 26 is made of soft rubber, it also acts as a buffer. When the connector is subjected to vibration or impact, the elasticity of the sealing ring 26 can absorb some of the energy, reducing direct impact on internal precision contacts and solder joints, thereby improving the reliability and lifespan of the connector.

[0031] like Figure 3 As shown, optionally, the inner ring of the outer shell 1 is provided with a limiting step, the limiting step includes a first step 15, the first limiting part 13 is provided on the inner side wall of the first step 15, and the outer peripheral wall of the base 22 abuts against the inner peripheral wall of the first step 15.

[0032] like Figure 3 As shown, optionally, the limiting step further includes a second step 16, the second limiting part 14 is disposed at one end of the second step 16 near the second opening 12, and the end of the bottom cover 4 away from the second opening 12 abuts against the second step 16.

[0033] The second step 16 restricts the axial installation distance of the bottom cover 4. When the bottom cover 4 abuts against the second step 16, the end of the bottom cover 4 near the second opening 12 has a cavity to accommodate the glue 5.

[0034] like Figure 3 As shown, optionally, the second step 16 and the mounting groove 25 are radially aligned to form a mounting cavity 17, in which the sealing ring 26 is accommodated.

[0035] like Figure 6 As shown, optionally, a second limiting opening 41 is provided on the side wall of the bottom cover 4, and the second limiting part 14 is limited in the second limiting opening 41 to prevent the bottom cover 4 from rotating.

[0036] like Figure 4 As shown, optionally, the inner wall of the housing 1 is provided with an L-shaped connecting groove 18, the connecting groove 18 is used to connect with an external device, the external device is provided with a connecting block (not shown), the connecting block is axially inserted into the connecting groove 18 and then rotated to fix it.

[0037] like Figure 1 As shown, optionally, the outer wall of the housing 1 is provided with an external thread, which is used for threaded connection with the external device.

[0038] Compared to existing technologies, the replaceable inner core connector of this utility model restricts the rotation of the inner core 2 through the first limiting part 13 and the second limiting part 14, which restricts the rotation of the bottom cover 4, preventing the inner core 2 and the bottom cover 4 from rotating and loosening, making installation simpler and more reliable. For different models of inner core 2, as long as the diameters of the base 22 and the bottom cover 4 are not changed, the base 22 is adapted to the first step 15, and the bottom cover 4 is adapted to the second step 16. Furthermore, the base 22 is provided with a first limiting port 23, and the bottom cover 4 is provided with a second limiting port 41. By changing the number of pins 3 and the number of first connecting holes 24 and second connecting holes 42, the outer shell 1 can be adapted to inner cores 2 with different numbers of pins 3. This achieves the effect of one model of outer shell 1 adapting to multiple models of inner core 2. During the production of the connector, multiple models of inner core 2 can be replaced for assembly, reducing production costs and facilitating assembly.
