[0043] On the one hand, please refer to Figures 1 to 6As shown, the first connector 100 first includes a first shielding shell 1. The first shielding shell 1 includes a sleeve portion 101 and a transition portion 102. The sleeve portion 101 includes a first main board 11, a first sub-board 12 and a pair of first side boards 13.

The front insertion port 103 is used for the plugging of the vehicle corner connector of the utility model with the docking connector (not shown). Therefore, when the second connector 200 is connected to the first connector 100, the second connector 200 is clamped by the first spring piece 1001 and the second spring piece 1002 in the front-to-back direction, thereby preventing the second connector 200 from tilting when being plugged into the rear insertion port 104, and ensuring the stability of the second connector 200 when connected to the first connector 100.

The rear insertion port 104 is used to connect the second connector 200 with the first connector 100. Specifically, the second connector 200 is inserted into the rear insertion port 104 to connect with the first connector 100.

[0045] Please refer to Figure 4 and Figure 15 As shown, the front insertion port 103 has a first opening direction, the rear insertion port 104 has a second opening direction, and there is an angle a between the first opening direction and the second opening direction. The value range of the angle a is 0 degrees to 180 degrees. Please refer to Figure 15, in a specific embodiment, the first opening direction is horizontally forward and the second opening direction is vertically downward, and the included angle a is 90 degrees. In this way, it is convenient for the second connector 200 to be inserted into the rear insertion port 104 and connected to the first connector 100 in a vertical state. In other embodiments, it can also be any other angle other than 90 degrees, such as 35 degrees or 135 degrees, etc., which can be adjusted according to customer requirements.

[0046] Please refer to Figure 6 As shown, the cover plate 15 includes a base portion 151 connected to the first main board 11 and a pair of side portions 152 disposed on opposite sides of the base portion 151 and fastened to the positioning plate 14. Therefore, in the present invention, the cover plate 15 is first integrally formed at the end of the first main board 11, and then the cover plate 15 is further bent so that the side portion 152 is fastened to the positioning plate 14. Naturally, the base portion 151 serves as a rear baffle for the rear insertion port 104. The first elastic piece 1001 is formed by stamping on the base portion 151 at the rear side of the rear insertion port 104, and the second elastic piece 1002 is formed by bending the rear end of the first sub-board 12 at the front side of the rear insertion port 104. Therefore, when the second connector 200 is inserted into the rear insertion port 104 and connected to the first connector 100, the second connector 200 can be clamped by the first elastic piece 1001 and the second elastic piece 1002 in the front-rear direction.

[0047] Please continue to refer to Figure 6 As shown, in a specific embodiment, the side portion 152 is provided with an elastic buckle 1520, and the positioning plate 14 is provided with a limiting notch 140. The elastic buckle 1520 cooperates with the limiting notch 140 to fasten the side portion 152 to the positioning plate 14. In other embodiments, the elastic buckle 1520 and the limiting notch 140 can also be interchanged, that is, the limiting notch 140 is provided on the side portion 152 and the elastic buckle 1520 is provided on the positioning plate 14, and the technical effect of fastening the side portion 152 to the positioning plate 14 can also be achieved. Therefore, in each side portion 152 of the present invention, one of the elastic buckle 1520 and the limiting notch 140 is provided, and in each positioning plate 14, the other of the elastic buckle 1520 and the limiting notch 140 is provided, and the technical effect of fastening the side portion 152 to the positioning plate 14 can be achieved.

[0048] Please refer to Figure 6 and Figure 22, the positioning plate, 14 is provided with a fourth elastic piece 1004, and the fourth elastic piece 1004 is arranged at the left and right sides of the rear insertion port 104 at intervals, and is used for clamping the second connector 200 in the left and right directions.

That is to say, the entire first shielding housing 1 is formed by stamping a whole metal plate, and the engagement between the swallowtail parts 121 and the swallowtail grooves 122 facilitates the enclosure of the first shielding housing 1 after forming, and further contributes to the stability of the enclosed accommodation space 10.

[0050] Secondly, please refer to Figures 1 to 6 , the first connector 100 of the present invention includes a first conductive terminal 3, a first insulating body 2 and the first shielding housing 1 as described above. The first shielding housing 1 covers the first insulating body 2, and the first insulating body 2 holds the first conductive terminal 3. The first connector 100 of the present invention can be docked with a docking connector (not shown) through the front insertion port 103, so as to transmit electrical signals between the first conductive terminal 3 and the docking terminal of the docking connector.

[0051] Please refer to Figure 4 , Figure 5 and Figure 20 , the outer wall surface of the first insulating body 2 is provided with a clamping groove 20, and the first main board 11 and / or the first sub-board 12 are provided with a plurality of third elastic pieces 1003, and the third elastic pieces 1003 are engaged with the clamping groove 20 to ensure the stability of the first shielding housing 1 covering the first insulating body 2.

[0052] Again, please refer to Figure 6 , Figure 10 and Figure 15 , a shielding housing combination of the present invention includes a second shielding housing 4 and the first shielding housing 1 as described above. As described above, the second shielding housing 4 is inserted from the rear insertion port 104 and is clamped by the first elastic piece 1001 and the second elastic piece 1002 on the front and rear sides of the rear insertion port 104. When the second connector 200 is inserted into the rear insertion port 104 to be connected to the first connector 100, the second shielding housing 4 can be clamped by the first elastic piece 1001 and the second elastic piece 1002 in the front and rear directions, thereby ensuring the connection stability between the second connector 200 and the first connector 100.

[0053] Please continue to refer to Figure 6 The adapter 102 includes a pair of fourth elastic pieces 1004 arranged opposite to each other. When the second connector 200 is inserted into the rear insertion port 104 and connected with the first connector 100, the second shielding shell 4 is also clamped by the pair of fourth elastic pieces 1004 in the left and right directions of the rear insertion port 104. Such an arrangement further ensures the connection stability between the second connector 200 and the first connector 100.

[0054] On the other hand, it is understandable that please refer to Figure 10 The utility model also relates to a second shielding shell 4, which includes a second main board 41, a second sub-board 42 and a pair of second side boards 43. The second main board 41 and the second sub-board 42 are arranged opposite to each other, and the pair of second side boards 43 are respectively connected to the opposite sides of the second main board 41 and the second sub-board 42. There is a storage space 40 between the second main board 41, the second sub-board 42 and the pair of second side boards 43, and the storage space 40 has an upper insertion port 401 and a lower insertion port 402 arranged oppositely. The end of each second side board 43 away from the upper insertion port 401 continues to extend downward to form an elastic cantilever 44, and each elastic cantilever 44 is provided with a limiting structure 440. The limiting structure 440 is located on the opposite inner side of the elastic cantilever 44. The utility model sets the second shielding shell 4 in this way, so that the second shielding shell 4 can not only be elastically locked on the second insulating body 5 while being covered by the second insulating body 5, but also facilitates the rapid separation between the second shielding shell 4 and the second insulating body 5 for easy maintenance.

[0055] For further information, please refer to Figure 7 In a specific embodiment, the limiting structure 440 is a convex hull; in other embodiments, the limiting structure 440 can also be in other shapes such as a spring sheet. In other words, the limiting structure 440 is either a convex hull or a spring sheet, as long as it can form a retaining force with the second insulating body 5 described below.

[0056] For further information, please refer to Figure 8 , Figure 9 and Figure 14The end of the second main board 41 is recessed toward the side facing the upper insertion port 401 to form a limiting groove 410, and the limiting groove 410 is used to abut against the boss portion 53 on the second insulating body 5. The assembly process of the second shielding shell 4 and the second insulating body 5 is that the second insulating body 5 is inserted into the second shielding shell 4 from bottom to top, and the limiting groove 410 abuts against the boss portion 53 to prevent over-insertion; after the limiting groove 410 abuts against the boss portion 53, the limiting structure 440 abuts against the second insulating body 5 to lock it in place.

[0057] Please refer to Figure 10 The second sub-plate 42 is provided with a plurality of dovetail portions 421 and a plurality of dovetail grooves 422, and the plurality of dovetail portions 421 and the plurality of dovetail grooves 422 are engaged with each other to form a joint line on the second sub-plate 42. In other words, the entire second shielding shell 4 is also formed by stamping a whole piece of metal plate, and the engagement between the dovetail portions 121 and the dovetail grooves 122 facilitates the enclosure of the second shielding shell 4 after molding, and is further conducive to the stability of the enclosed storage space 40.

[0058] Similarly, the second connector 200 involved in the utility model includes a second conductive terminal 6, a second insulating body 5 and the second shielding shell 4 as described above. The second shielding shell 4 covers the second insulating body 5, and the second insulating body 5 holds the second conductive terminal 6. The limiting structure 440 is used to keep the second insulating body 5 in the storage space 40. The second insulating body 5 has a step portion 50, and the limiting structure 440 can abut and separate from the step portion 50. The second shielding shell 4 of the second connector 200 of the utility model is covered with the second insulating body 5, and can not only be elastically locked on the second insulating body 5 through the elastic cantilever 44, but also the elastic cantilever 44 facilitates the rapid separation between the second shielding shell 4 and the second insulating body 5 for easy maintenance.

[0059] Please refer to Figure 4 , Figure 5 , Figure 16 and Figure 18 , is a connection diagram of the first conductive terminal 3, the second conductive terminal 6 and the cable 8 of the vehicle corner connector of the utility model. The first conductive terminal 3 includes two first power terminals 31 located at the outermost sides and two first signal terminals 32 located in the middle. Correspondingly, the second conductive terminal 6 also includes a second power terminal 61 and a second signal terminal 62. In this way, the first power terminal 31 is connected to the second power terminal 61 and the first signal terminal 32 is connected to the second signal terminal 62 to transmit power and signals.

[0060] Please refer toFigures 7 to 9 The second insulating body 5 has a first end face 51 facing the upper insertion port 401 and a second end face 52 facing away from the upper insertion port 401, and the step portion 50 is located between the first end face 51 and the second end face 52. That is to say, the limiting structures 440 of the elastic cantilevers 44 are specifically at the step portions 50 on both sides of the second insulating body 5. After the two limiting structures 440 of the two elastic cantilevers 44 are respectively abutted against the two step portions 50 on the opposite sides, a holding force for the second insulating body 5 in the second shielding housing 4 can be provided.

[0061] Still referring to Figure 8 、 Figure 9 and Figure 14 The end of the second main board 41 is recessed towards the side facing the upper insertion port 401 to form a limiting groove 410, and the second end face 52 of the second insulating body 5 has a boss portion 53 that can protrude upwards into the limiting groove 410 for abutting. As described above, the limiting groove 410 abuts against the boss portion 53 to prevent over-insertion during the process of inserting the second insulating body 5 into the second shielding housing 4 from bottom to top.

[0062] Finally, please refer to Figures 1 to 17 The present utility model also relates to a housing combination, which includes an outer housing 7 and the second shielding housing 4 as described above. The outer housing 7 is sleeved outside the second shielding housing 4. The inner wall surface of the outer housing 7 includes a clamping structure, and the second shielding housing 4 includes a clamping position structure. The clamping structure cooperates with the clamping position structure to clamp and fix the second shielding housing 4 to the outer housing 7. In a specific embodiment, the clamping structure is a clamping groove 701, and the clamping position structure is a clamping elastic arm 4005. Through the cooperation of the clamping groove 701 and the clamping elastic arm 4005, the holding force between the second shielding housing 4 and the outer housing 7 is further improved. Therefore, an effective buckling connection is formed between the second shielding housing 4 and the second insulating body 5 and between the second shielding housing 4 and the outer housing 7.

[0063] Please refer to Figures 8 to 11 、 Figure 13 、 Figure 15 、 Figure 16 and Figure 22 The second shielding housing 4 includes a pair of positioning convex portions 4006, and the positioning convex portions 4006 are respectively located on the second side plates 43. The positioning convex portions 4006 are closer to the lower insertion port 402 than the clamping elastic arms 4005, and are used for abutting against the inner wall surface of the outer housing 7.

[0064] Furthermore, please refer to Figures 1 to 3 andFigure 7 The housing assembly of the utility model further comprises a first shielding housing 1, and the outer housing 7 is sleeved outside the first shielding housing 1. The outer housing 7 is provided with two different end openings 70, and the different end openings 70 mentioned here include Figure 3 A forward end opening 70 and Figure 7 The first shielding shell 1 and the second shielding shell 4 are respectively inserted into the outer shell 7 from two different end openings 70, that is, the first shielding shell 1 is inserted backwards into the outer shell 7 from the end opening 70 facing forwards, and the second shielding shell 4 is inserted upwards into the outer shell 7 from the end opening 70 facing downwards. Therefore, the assembly of the first shielding shell 1 and the second shielding shell 4, or the assembly of the first connector 100 and the second connector 200, does not interfere with each other.

[0065] The first shielding shell 1 includes a sleeve portion 101 and a transition portion 102, wherein the transition portion 102 surrounds a plurality of spring pieces of the rear insertion port 104. The spring pieces mentioned here specifically include a first spring piece 1001, a second spring piece 1002, and a fourth spring piece 1004. When the second connector 200 is inserted into the rear insertion port 104 and connected with the first connector 100, the first spring piece 1001, the second spring piece 1002, and the fourth spring piece 1004 respectively abut against the second main board 41, the second sub-board 42, and a pair of second side boards 43 in multiple directions, including front, rear, left, and right.

[0066] For further information, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The first shielding shell 1 has a fifth elastic piece 1005 facing away from the receiving space 10, which has the same function as the second shielding shell 4 also having a locking elastic arm 4005 facing away from the receiving space 40. That is, the fifth elastic piece 1005 provided on the first shielding shell 1 and the locking elastic arm 4005 provided on the second shielding shell 4 are both used for locking with the outer shell 7 respectively, so as to provide a holding force between the first shielding shell 1, the second shielding shell 4 and the outer shell 7.

[0067] The abutment and snap-fit provide different holding forces. Abutment means interference fit and provides a smaller holding force; snap-fit provides a larger holding force and is more difficult to separate.

[0068] In summary, the beneficial effects of the present utility model at least include: elastic cantilevers 44 are respectively arranged on both sides of the second shielding housing 4 of the second connector 200, and a pair of limiting structures 440 are located on the opposite inner sides of the pair of elastic cantilevers 44. After being respectively abutted against the two step portions 50 on the opposite sides of the second insulating body 5, a holding force for the second insulating body 5 in the second shielding housing 4 can be provided. Therefore, not only can the second shielding housing 4 be elastically latched on the second insulating body 5 to provide a holding force, but also the second shielding housing 4 can be quickly separated from the second insulating body 5 for convenient maintenance.

[0069] The above embodiments are only used to illustrate the present utility model and do not limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art of the relevant technical field. Although this specification has described the present utility model in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still modify the present utility model or make equivalent replacements, and all technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
