[0041] Referring to Figures 1 to 4 According to the LED support 10 with a limiting structure of the first aspect embodiment of the utility model, the LED support 10 with a limiting structure is installed in the connector, the connector includes the light-emitting assembly 20, the light-emitting assembly 20 includes circuit board 21 and light source 22, and the light source 22 is arranged on the circuit board 21, and the LED support 10 with a limiting structure includes: first fixed seat 11 and limiting seat 12. First fixed seat 11 is arranged in the connector, and limiting seat 12 is arranged on first fixed seat 11, one end of circuit board 21 is inserted in limiting seat 12, and the welding point on circuit board 21 is located at the other end of circuit board 21.

[0042] The LED support 10 with a limiting structure of the utility model passes through first fixed seat 11 and limiting seat 12, effectively solve the problem that the circuit board 21 is warped in the welding process of traditional network connector. The structure not only ensures the stable installation of light source 22, but also greatly improves the reliability and durability of the connector. By inserting one end of the circuit board 21 into the limiting seat 12, the movement of the circuit board 21 during welding is limited, and the circuit board 21 warping phenomenon caused by welding is avoided, so that the light guide plate of the connector is protected from damage, and the normal display effect of the indicator light is ensured. In addition, the fixing structure is simple and easy to manufacture and assemble, reduces the production cost, improves the production efficiency, and provides strong technical support for the optimization design and production of network connector.

[0043] Specifically, the fixing structure is installed inside the connector, and the connector includes the light-emitting assembly 20, and the light-emitting assembly 20 is composed of the circuit board 21 and the light source 22 arranged thereon. In order to stably fix the light source 22 and prevent the circuit board 21 from warping, the first fixed seat 11 and the limiting seat 12 are designed in the embodiment. The first fixed seat 11 is firmly arranged inside the connector and provides support for the entire fixing structure. The limiting seat 12 is arranged on the first fixed seat 11, and its shape and size are matched with the end of the circuit board 21. When assembling, one end of the circuit board 21 is inserted into the limiting seat 12, and the welding point on the circuit board 21 is located at the other end of the circuit board 21, that is, the side away from the limiting seat 12. In this way, even if the soldering iron is pressed on the welding point during welding, the circuit board 21 will not be warped because one end of the circuit board 21 is firmly fixed by the limiting seat 12, thereby effectively protecting the light guide plate of the connector and the circuit board 21 itself, and ensuring the normal operation of the indicator light and the stability of the connector.

[0044] Therefore, it can be understood that the LED support 10 with the limiting structure has at least the following beneficial effects: one end of the light-emitting assembly 20 is inserted into the limiting seat 12, and the one end of the light-emitting assembly 20 is limited in the limiting seat 12 through the limiting seat 12, so that the other end of the circuit board 21 is prevented from being lifted when the soldering point at one end of the circuit board 21 is soldered by using the electric soldering iron, and the circuit board 21 is further prevented from being in contact with the light guide structure 40 of the connector.

[0045] Further, with reference to Figures 3 to 4 In some embodiments of the utility model, the first fixed seat 11 includes: fixed plate 111 and mounting plate 112. Fixed plate 111 is located at the bottom of the connector, and the limiting seat 12 is installed at the upper end of fixed plate 111;Mounting plate 112 is arranged at the upper end of fixed plate 111 and is located at one side of limiting seat 12, and the mounting groove 121 is defined between limiting seat 12 and mounting plate 112, one end of light-emitting assembly 20 is inserted into mounting groove 121, and the circuit board 21 is abutted to one side surface of mounting plate 112.

[0046] Specifically, the first fixed seat 11 includes two parts of the fixed plate 111 and the mounting plate 112. The fixed plate 111 is located at the bottom of the connector and provides a stable support base for the entire fixed structure. The limiting seat 12 is installed at the upper end of the fixed plate 111 and is tightly connected with the fixed plate 111 to ensure the stability of the limiting seat 12. In addition, the mounting plate 112 is arranged at the upper end of the fixed plate 111 and is located at one side of the limiting seat 12. The limiting seat 12 and the mounting plate 112 define a mounting groove 121 therebetween, and the size and shape of the mounting groove 121 are matched with one end of the light-emitting assembly 20. During assembly, one end of the light-emitting assembly 20 (including the circuit board 21 and the light source 22 arranged thereon) is inserted into the mounting groove 121, and the circuit board 21 is abutted to one side surface of the mounting plate 112. Such a design not only ensures the accurate positioning and stable installation of the light-emitting assembly 20, but also further limits the movement of the circuit board 21 during soldering. Since the circuit board 21 is firmly abutted to the mounting plate 112, even if the electric soldering iron exerts pressure on the soldering point during soldering, the circuit board 21 will not be lifted or deviated, thereby effectively protecting other components of the connector, such as the light guide plate, and ensuring the overall performance and reliability of the connector.

[0047] With reference to Figures 3 to 4 In some embodiments of the utility model, the limiting seat 12 includes a first limiting part 122 and a second limiting part 123, the first limiting part 122 and the second limiting part 123 are arranged on two sides of the first fixed seat 11 respectively, and the first limiting part 122 and the second limiting part 123 are oppositely arranged, and one end of the circuit board 21 is inserted between the first limiting part 122 and the second limiting part 123.

[0048] Specifically, the limiting seat 12 includes a first limiting part 122 and a second limiting part 123, which are respectively arranged on both sides of the first fixed seat 11 and oppositely arranged to form a clamping structure. During assembly, one end of the circuit board 21 is inserted between the first limiting part 122 and the second limiting part 123. This design ensures that the circuit board 21 can be stably clamped after being inserted and will not easily loosen or fall off due to external force. The opposite arrangement of the first limiting part 122 and the second limiting part 123 not only provides precise positioning for the circuit board 21, but also effectively limits the movement of the circuit board 21 during welding, thereby avoiding problems such as warping or deviation of the circuit board 21 caused by welding.

[0049] In addition, the specific shape and size of the first limiting part 122 and the second limiting part 123 can be designed according to actual needs to adapt to circuit boards 21 of different specifications and sizes. This flexible design makes the LED support 10 with a limiting structure of the utility model have a wider application range and can meet the needs of different types and specifications of connectors for the light source 22 fixing structure. Through the design of this structure, not only the stability and reliability of the connector are improved, but also the assembly process is simplified and the production cost is reduced.

[0050] Referring to Figures 2 to 4 In some embodiments of the utility model, the first fixed seat 11 is provided with a plurality of clamping grooves 13, and the plurality of clamping grooves 13 are used for embedding the first connecting terminal 23. The first connecting terminal 23 is used for connecting the welding point on the circuit board 21. One end of the first connecting terminal 23 extends to the upper end of the first fixed seat 11 and is connected with the welding point on the circuit board 21. The other end of the first connecting terminal 23 extends outward from the lower end of the first fixed seat 11 to the connector.

[0051] Further, a plurality of clamping grooves 13 are further designed on the first fixed seat 11 in this embodiment. These clamping grooves 13 are used for embedding the first connecting terminal 23. During specific assembly, one end of the first connecting terminal 23 is embedded into the clamping groove 13 and extends upward to tightly connect with the welding point on the circuit board 21. This design not only ensures the stability and reliability of the circuit connection, but also makes the welding process more convenient and fast. At the same time, the other end of the first connecting terminal 23 extends downward, passes through the first fixed seat 11, and finally extends outward to the connector, which is convenient for connecting with external circuits or devices. The design of the clamping groove 13 not only provides precise positioning for the first connecting terminal 23, but also enhances the connection strength between the first connecting terminal 23 and the first fixed seat 11 through the embedding effect, thereby improving the stability and durability of the entire LED support 10 with a limiting structure. In addition, the number and layout of the clamping grooves 13 can be adjusted according to actual needs to adapt to different specifications and quantities of the first connecting terminal 23, further improving the flexibility and practicality of the utility model.

[0052] With reference to Figures 1 to 3 According to the second aspect of the utility model, the light-emitting connector 1 comprises the LED support 10 with the limiting structure of any one of the first aspect, and the light-emitting connector 1 further comprises a light-emitting assembly 20, and the light-emitting assembly 20 is installed in the LED support 10 with the limiting structure.

[0053] Specifically, the light-emitting connector 1 comprises the light-emitting assembly 20, and in the installation process, the light-emitting assembly 20 is installed in the LED support 10 with the limiting structure. This fixing structure, as described in the above embodiment, is composed of key components such as the first fixing seat 11 and the limiting seat 12, which collectively provide stable support and protection for the light-emitting assembly 20. Through this structure, the circuit board 21 is firmly fixed at the predetermined position, and the light source 22 is also stably installed on the circuit board 21, thereby ensuring the stable emission and transmission of the optical signal. In addition, the design of the LED support 10 with the limiting structure also fully considers various factors in the welding process, such as welding temperature and welding pressure, and through the ingenious limiting and clamping design, the problem of the circuit board 21 being warped or deviated during the welding process is effectively avoided. This not only protects the light-emitting assembly 20 from damage, but also greatly improves the overall reliability and durability of the connector.

[0054] Therefore, it can be understood that the light-emitting connector 1 according to the utility model embodiment has at least the following beneficial effects: the connector can be fixed by the LED support 10 with the limiting structure of any one of the first aspect, thereby fixing the circuit board 21 of the light-emitting assembly 20 in the light-emitting connector 1, preventing the other end of the circuit board 21 from being warped when the soldering iron is used to solder the solder joint at one end of the circuit board 21, thereby preventing the circuit board 21 from interfering with the light guide structure 40 of the connector, and finally ensuring the overall performance and reliability of the network connector.

[0055] Further, with reference to Figures 1 to 3 In some embodiments of the utility model, the light-emitting connector 1 further comprises an insulating body 30, the insulating body 30 is provided with an insertion cavity 31, the insertion cavity 31 is used for inserting the transparent crystal head 2, the LED support 10 with the limiting structure and the light-emitting assembly 20 are arranged in the insertion cavity 31, and the light-emitting assembly 20 is located at the front side of the LED support 10 with the limiting structure. This insulating body 30 not only provides necessary electrical isolation and protection for the connector, but also ingeniously designs an insertion cavity 31.

[0056] The insertion cavity 31 is an important part of the insulating body 30, which can insert the transparent crystal head 2. The transparent crystal head 2 serves as an important interface for the connector to connect with external devices, and its stability and reliability are crucial to the performance of the entire connector. By inserting it into the insertion cavity 31, the transparent crystal head 2 can be effectively protected from external environmental interference and damage. More importantly, the LED support 10 with a limiting structure and the light emitting assembly 20 are both arranged in the insertion cavity 31. The light emitting assembly 20 is located on the front side of the LED support 10 with a limiting structure, which not only ensures the stable emission of the light source 22, but also enables the smooth transmission of optical signals through the transparent crystal head 2. At the same time, since the light emitting assembly 20 and the LED support 10 with a limiting structure are both firmly installed in the insertion cavity 31, the structure of the entire connector is more compact and stable, which can effectively resist external impact and vibration.

[0057] Further, referring to Figures 1 to 3 In some embodiments of the present application, the light emitting connector 1 further comprises a light guide structure 40, which is arranged in the insertion cavity 31 and located on the front side of the light emitting assembly 20.

The light guide structure 40 is made of light-transmitting material, which has excellent light transmission performance and optical stability, and can ensure that the loss of optical signals during transmission is minimized. At the same time, the shape and size of the light guide structure 40 are also precisely designed to match the shape and size of the light emitting assembly 20 and the transparent crystal head 2, so as to realize efficient and stable transmission of optical signals. During assembly, the light guide structure 40 is firmly installed in the insertion cavity 31 and tightly contacts with the light emitting assembly 20 and the transparent crystal head 2. When the light emitting assembly 20 emits optical signals, these signals will first irradiate onto the light guide structure 40, and then be guided and transmitted through the light guide structure 40, and finally transmitted to external devices through the transparent crystal head 2.

[0058] Further, referring to Figures 1 to 3 In some embodiments of the present application, the light emitting connector 1 further comprises a second fixing seat 50, which is arranged in the insertion cavity 31 and located on the rear side of the first fixing seat 11.

The reinforcing seat 52 is located on the rear side of the first fixing seat 11, and the other end of the second connecting terminal 53 is embedded in the reinforcing seat 52 and extends out of the insulating body 30.

[0059] The second fixing seat 50 is mainly composed of a tongue plate 51 and a reinforcing seat 52. The tongue plate 51 is located on the upper side of the first fixing seat 11 and provides a stable support platform for the second connecting terminal 53. During assembly, one end of the second connecting terminal 53 is accurately arranged on the tongue plate 51 and is tightly connected with the tongue plate 51 through welding or other fixing methods.

[0060] The reinforcing seat 52 is located on the rear side of the first fixing seat 11 and has a solid structure, which can effectively enhance the overall mechanical strength of the connector. The other end of the second connecting terminal 53 is embedded in the reinforcing seat 52 and extends out of the insulating body 30 through the reinforcing seat 52, which is convenient for connecting with external circuits or devices. This design not only ensures the stability and reliability of the second connecting terminal 53, but also makes the connection of the connector more convenient and efficient.

[0061] Further, referring to Figures 1 to 3 In some embodiments of the present application, the end of the second connecting terminal 53 connected with the crystal head 2 is bent downward, and the lower end of the light guide structure 40 is provided with a plurality of accommodation grooves 41, which are arranged in a transverse direction and correspond to the positions of the second connecting terminal 53.

[0062] Specifically, the design of the second connecting terminal 53 and the light guide structure 40 is further optimized in this embodiment. In particular, the end of the second connecting terminal 53 connected with the crystal head 2 is designed to be bent downward, which not only saves space but also makes the connection more compact and stable. At the same time, in order to cooperate with the bending design of the second connecting terminal 53, the lower end of the light guide structure 40 is also provided with a plurality of accommodation grooves 41. These accommodation grooves 41 are arranged in a transverse direction and correspond to the positions of the second connecting terminal 53. During assembly, the end of the second connecting terminal 53 is embedded in the corresponding accommodation groove 41, thereby realizing the accurate cooperation between the light guide structure 40 and the second connecting terminal 53.

[0063] Referring to Figure 1In some embodiments of the present application, the insulating body 30 is provided with two rows of insertion cavities 31, and each row of insertion cavities 31 includes a plurality of insertion cavities 31 arranged transversely at intervals. Such a design not only enables the light-emitting connector 1 to support the insertion of multiple transparent crystal heads 2 at the same time, but also greatly improves the integration and use efficiency of the connector. In actual application, single-row or double-row insertion cavities 31 can be selected for use according to needs, or two rows of insertion cavities 31 can be used at the same time to achieve more complex and efficient connection. The plurality of insertion cavities 31 in each row of insertion cavities 31 are kept at a certain transverse interval, which not only ensures the independence between the insertion cavities 31, but also facilitates the insertion and extraction operations of the transparent crystal head 2. At the same time, since each insertion cavity 31 is provided with a complete LED support 10 with a limiting structure, a light-emitting assembly 20, and a light guide structure 40, etc., each insertion cavity 31 can independently realize the emission and transmission of optical signals without interference.

[0064] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
