[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0042] The present application provides a elbow connector. As shown in Figures 1 to 4 , the elbow connector 10 includes a shell 100, a shielding shell 200, an insulator 300, an insulating rear cover 400, and a terminal 500. As shown in Figure 3 and Figure 4 , the terminal 500 is a bent structure. As shown in Figure 4 , the terminal 500 includes a long terminal 510 and a short terminal 520. The short terminal 520 is arranged on the inner side of the long terminal 510. As shown in Figure 4 , the terminal 500 in the present application is divided into two layers, the inner layer is the short terminal 520, and the outer layer is the long terminal 510. Each layer of the terminal 500 has two terminals. The front end of the long terminal 510 and the short terminal 520 is inserted into the insulator 300. As shown in Figure 3 and Fig. 4, the insulating rear cover 400 is arranged on the rear end of the insulator 300 to fix the rear end of the terminal 500. The shielding shell 200 and the shell 100 are arranged on the outer side of the insulator 300 in sequence. The shielding shell 200 is a metal shell. The shell 100 is a shell 100 of insulating material such as plastic.

[0043] In the present application, in combination with Figures 4 to 6 , the insulating rear cover 400 is a folded structure. As shown in Figure 6 , the insulating rear cover 400 includes a rear cover body 410 and a rear cover cover plate 420. As shown in Figure 7As shown, a short terminal channel 521 is formed between the front side of the rear cover body 410 and the rear end of the insulator 300. Figure 3 , the rear end of the short terminal 520 is fixed in the short terminal channel 521. Figure 7 As shown, a long terminal channel 511 is formed between the rear side of the rear cover body 410 and the front side of the rear cover plate 420. Figure 3 The rear end of the long terminal 510 is fixed in the long terminal channel 511 .

[0044] In the embodiment of the present application, the insulating back cover 400 is designed as a folding structure, including a back cover body 410 and a back cover plate 420. A short terminal channel 521 is formed between the front side of the back cover body 410 and the rear end of the insulator 300, and the rear end of the short terminal 520 is fixed in the short terminal channel 521. A long terminal channel 511 is formed between the rear side of the back cover body 410 and the front side of the back cover plate 420, and the rear end of the long terminal 510 is fixed in the long terminal channel 511. As a result, the insulating back cover 400 can simultaneously form a long terminal channel 511 for the long terminal 510 to pass through and a short terminal channel 521 for the short terminal 520 to pass through, facilitating the assembly of the long terminal 510 and the short terminal 520. The structure is streamlined, the number of parts is small, the assembly is convenient, and the assembly efficiency is high.

[0045] At the same time, a short terminal channel 521 for accommodating the short terminal 520 and a long terminal channel 511 for accommodating the long terminal 510 are formed. Each terminal is accommodated through an independent channel, so that the short and long terminals 520 are independently insulated from each other.

[0046] In one embodiment, if Figure 8 As shown, the rear end of the insulator 300 is provided with a first slot 301. Figure 5 As shown, the front end of the rear cover body 410 of the insulating rear cover 400 is provided with a second slot 411. Figure 5 、 Figure 7 and Figure 8 As shown, the first slot 301 and the second slot 411 are buckled together to form a short terminal channel 521. Figure 6 As shown, the rear end of the rear cover body 410 of the insulating rear cover 400 is provided with a third card slot 412, and the front end of the rear cover plate 420 of the insulating rear cover 400 is provided with a fourth card slot 421. Figures 6 to 8 As shown, the third latching slot 412 and the fourth latching slot 421 are engaged with each other to form a long terminal channel 511 .

[0047] In the embodiment of the present application, a channel (long terminal channel 511 and short terminal channel 521) is formed by providing slots on two opposing end surfaces and engaging the slots. For example, the rear end of the insulator 300 and the front end of the rear cover body 410 are opposite each other. The rear end of the insulator 300 is provided with a first slot 301, and the front end of the rear cover body 410 is provided with a second slot 411. The first slot 301 and the second slot 411 engage to form the short terminal channel 521. In other optional embodiments, a slot may be provided on one of the two opposing end surfaces, while the other end surface is provided as a flat surface. This end surface does not have a slot and only serves as a stop and fixation.

[0048] refer to Figure 6 As shown, the insulating rear cover 400 is an integrally formed structure. One side of the rear cover plate 420 of the insulating rear cover 400 is rotatably connected to the rear cover body 410 of the insulating rear cover 400 through a connecting rib 430, as shown in FIG. Figure 6 As shown, the rotation axis is I. The other side of the rear cover plate 420 is connected to the rear cover body 410 through a snap. After the long terminal 510 is fixed in the corresponding slot on the insulating rear cover 400, the rear cover plate 420 is rotated and clamped. Figure 9 Integrating the back cover body 410 and the back cover plate 420 of the insulating back cover 400 can reduce the number of parts and ease assembly difficulty.

[0049] Further, such as Figure 8 As shown, the front end of the rear cover body 410 is provided with a first buckle 413 extending forward, and the insulating rear cover 400 is connected to the insulator 300 through the first buckle 413. It can be understood that, as Figure 8 As shown, a first buckle groove 302 for accommodating the first buckle 413 is provided on the insulator 300 .

[0050] Since the terminal 500 is a bent structure, the insulator 300 is also designed to be a bent structure accordingly. Figure 8 As shown, the insulator 300 includes a transverse portion 310 and a longitudinal portion 320 , and the first buckle groove 302 is provided on the longitudinal portion 320 .

[0051] In the embodiment of this application, Figure 10 As shown, the terminal 500 is an integrally formed structure. Figure 10 As shown, the terminal 500 includes a contact portion 501, a bent portion 502 and a wiring portion 503, which are formed by stamping the same plate. The bent portion 502 connects the contact portion 501 and the wiring portion 503, and the contact portion 501 is used to connect to the docking connector, such as Figure 10 As shown, the contact portion 501 is generally wound into a cylindrical shape to facilitate the insertion of the terminal 500 of the mating connector. The wiring portion 503 is used to connect the cable 20. Figure 10As shown, the bending part 502 is in a sheet shape, facilitating bending of the terminal 500. As shown, Figure 11 As shown, the terminal 500 is in a straight shape when punched, which is high in material utilization and convenient for packaging and turnover. As shown, Figure 11 As shown, a notch 504 is reserved at the terminal 500 close to the wiring part 503, forming the sheet-shaped bending part 502. The sheet-shaped bending part 502 can be used to bend the straight terminal 500 into a bent terminal 500 when riveting the terminal 500, and the terminal 500 is immediately loaded into the insulator 300 and the insulating back cover 400 after riveting, thereby achieving the desired effect of assembling the elbow connector 10. In the prior art, the plate material is directly punched into a right-angle terminal when the terminal is formed, which is low in material utilization, has a risk of being knocked off during packaging and turnover, and is high in production cost.

[0052] As shown, Figure 10 As shown, the wiring part 503 includes a pair of clamping arms 5031 oppositely arranged and capable of clamping the cable 20. It can also be said that the wiring part 503 is actually a cable clamp used to clamp the cable 20 and connect the terminal 500 to the cable 20.

[0053] As shown, Figure 4 As shown, the shielding shell 200 includes a shielding front shell 210 and a shielding back shell 220. The shielding front shell 210 is sleeved on the insulator 300, and the shielding back shell 220 is coveringly arranged at the rear end of the shielding front shell 210, thereby enclosing the terminal 500 in the shielding shell 200 to avoid electromagnetic interference and improve the stability of signal transmission.

[0054] As shown, Figure 4 As shown, the shielding front shell 210 includes a receiving part 211 and an extension part 212. The receiving part 211 is used to receive the insulator 300 and the terminal 500. The extension part 212 extends downward from the bottom of the receiving part 211. As shown, Figure 4 , the shielding back shell 220 includes a covering part 221 and a clamping part 222. The covering part 221 is coveringly arranged at the rear end of the receiving part 211, and the extension part 212 extends downward from the covering part 221. The clamping part 222 is provided with oppositely arranged clamping arms capable of clamping the extension part 212 to press the shielding front shell 210 on the cable 20.

[0055] As shown, Figure 4 As shown, the cable 20 includes an inner core 21 and a braided layer (not shown in the figure) arranged outside the inner core 21. The inner core 21 is connected to the terminal 500, and the braided layer is connected to the shielding front shell 210. The clamping arm 2221 can press the extension part 212 to the braided layer of the cable 20 after clamping the extension part 212, thereby making the braided layer tightly contact with the shielding front shell 210.

[0056] Referring to Figure 1 and Figure 4As shown, the shell 100 is sleeved on the outer side of the shielding shell 200 from front to back, and the front end of the shell 100 is provided with an opening 101 for inserting the mating connector. As shown Figure 3 As shown, the shell 100 is provided with a second buckle 110, and the outer periphery of the shielding shell 200 is provided with a second buckle groove 2111 for cooperating with the second buckle 110. As shown Figure 4 As shown, the second buckle groove 2111 can be arranged around the shielding shell 200, which is convenient for forming the second buckle groove 2111 on the shielding shell 200.

[0057] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0058] The above-described embodiments only express the implementation of the present application, and the description is more specific and detailed, but it should not be construed as limiting the scope of the patent application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the scope of the patent protection of the present application should be subject to the appended claims.
