Description

[Technical Field]

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector with increased structural strength. [Background Technology]

[0002] An existing electrical connector is mounted on a panel for mating with a mating connector. The mating connector includes multiple mating terminals and a locking part. The electrical connector includes an insulating body and multiple conductive terminals housed within the insulating body. The side wall of the insulating body includes a locking groove for locking the locking part. The insulating body also includes a stop block protruding outward from the side wall for being stopped from moving by the panel. The conductive terminals are used to mate with the mating terminals.

[0003] The above structure has the following problems:

[0004] The side wall protrudes outward to form a stop block, which is used to stop the movement of the panel. Because the side wall has a fastening groove, the side wall is relatively weak, which makes it easy for the side wall to deform when the stop block is subjected to the supporting force of the panel.

[0005] Therefore, it is necessary to design a new electrical connector to overcome the above problems. [Utility Model Content]

[0006] In view of the problems faced by the prior art, the purpose of this invention is to provide an electrical connector with an insulating body including a first limiting part protruding outward from the side wall and a second limiting part protruding inward from the side wall, wherein the first limiting part is at least partially aligned with the second limiting part, thereby strengthening the side wall and making the side wall less prone to deformation.

[0011] Furthermore, the outer surface of the first wall portion includes a vertical surface and an inclined surface connecting the vertical surface, the inclined surface connecting the second wall portion, and the first limiting portion connecting both the vertical surface and the inclined surface.

[0012] Furthermore, the locking grooves in the front-to-back direction jointly penetrate the first wall and the second wall.

[0013] Furthermore, the insulating body also includes at least one third limiting part protruding outward from the side wall.

[0014] Furthermore, the insulating body also includes a third limiting part that protrudes outward from the side wall.

The first limiting part will receive the supporting force applied by the panel. Since the side wall on the side of the second docking groove is provided with a locking groove, the strength of the side wall is relatively weak. As a result, when the first limiting part moves in the vertical direction and is subjected to the supporting force of the panel, the side wall is easy to deform. By protruding at least one second limiting part inward from the side wall, and at least part of the first limiting part and the second limiting part are aligned in the front-back direction, the strength of the side wall is increased, so that when the first limiting part is used to be stopped by the panel from moving upward and / or downward, the side wall is not easy to deform. At the same time, the second limiting part is located on at least one side of the front and back sides of the first docking groove and is used to stop the movement of the docking body.

In other embodiments, the first limiting portion 15 may be fully aligned with the second limiting portion 16 in the front-rear direction, and the third limiting portion 17 may be fully aligned with the second limiting portion 16. In this embodiment, the elastic arm 19 extends from one of the two end walls 12 away from the first mating groove 13.

[0041] like Figures 2 to 5 As shown, the first limiting part 15 is located on the upper side of the panel 200 and is used to be stopped from moving downward by the panel 200; the third limiting part 17 is located on the lower side of the panel 200 and is used to be stopped from moving upward by the panel 200; the elastic arm 19 is located on the lower side of the panel 200 and is used to be stopped from moving upward by the panel 200; and the fastening part 20 is located on the upper side of the elastic arm 19 and is used to engage with the fastening groove 201 for locking. In other embodiments, the first limiting part 15 may also be located on the lower side of the panel 200 and is used to be stopped from moving upward by the panel 200; the third limiting part 17 may also be located on the upper side of the panel 200 and is used to be stopped from moving downward by the panel 200; the elastic arm 19 may be located on the upper side of the panel 200 and is used to be stopped from moving downward by the panel 200; and the fastening part 20 may be located on the lower side of the elastic arm 19. In some other embodiments, the first limiting part 15 may also be located on the upper and lower sides of the panel 200 and be blocked by the panel 200 from moving upward and downward.

[0042] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the second limiting part 16 is located on the front side of the first docking groove 13. The second limiting part 16 is used to stop the docking body 301 from moving forward, and the first side wall 11a is used to stop the docking body 301 from moving backward. In other embodiments, the second limiting part 16 may also be located on the rear side of the first docking groove 13, and the second limiting part 16 is used to stop the docking body 301 from moving backward, and the first side wall 11a is used to stop the docking body 301 from moving forward. In some other embodiments, the insulating body 1 also includes two second limiting parts 16 protruding inward from the first side wall 11a and two second limiting parts 16 protruding inward from the second side wall 11b. The second limiting part 16 connected to the second side wall 11b is located on the front side of the first docking groove 13 and is used to stop the docking body 301 from moving forward. The second limiting part 16 connected to the first side wall 11a is located on the rear side of the first docking groove 13 and is used to stop the docking body 301 from moving backward.

[0043] like Figure 5 and Figure 6 As shown, two second limiting portions 16 protruding inward from the second sidewall 11b are respectively connected to two end walls 12. The width of the second limiting portion 16 in the left-right direction is greater than the width of the first limiting portion 15. The center line L of the first mating groove in the front-back direction is misaligned with the fastening portion 20, and the misalignment is controlled within 0.5mm to 1.5mm. Each material extraction hole 18 is located on a second limiting portion 16 and one of the end walls 12 connecting the second limiting portion 16, and is not located on the second sidewall 11b.

[0044] like Figures 7 to 9 As shown, the second sidewall 11b includes a first wall portion 112, a second wall portion 113 upwardly connected to the first wall portion 112, and a locking groove 111 recessed in the front-rear direction. The thickness of the first wall portion 112 in the front-rear direction is greater than the thickness of the second wall portion 113. In this embodiment, the locking groove 111 in the front-rear direction passes through both the first wall portion 112 and the second wall portion 113. In other embodiments, the locking groove 111 is recessed in the rear-forward direction and does not pass through the first wall portion 112 and the second wall portion 113. In some other embodiments, the locking groove 111 either passes entirely through the first wall portion 112 in the front-rear direction or is recessed entirely in the rear-forward direction and does not pass through the first wall portion 112.

[0045] like Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, two first limiting portions 15 protrude outward from the first wall portion 112, with the lower surface of the first limiting portion 15 located at the connection between the first wall portion 112 and the second wall portion 113. A third limiting portion 17 protrudes outward from the second wall portion 113, and the position where the third limiting portion 17 connects to the second wall portion 113 is below the locking groove 111. The width of the third limiting portion 17 in the left-right direction is greater than the width of the locking groove 111. In other embodiments, the two first limiting portions 15 protrude outward from the second wall portion 113, and the third limiting portion 17 protrudes outward from the first wall portion 112. The position where the third limiting portion 17 connects to the first wall portion 112 can be located above the locking groove 111. In this embodiment, the locking groove 111 in the left-right direction is partially located between the positions where the two first limiting portions 15 connect to the first wall portion 112. In other embodiments, the entire locking groove 111 in the left-right direction is located between the positions where the two first limiting portions 15 connect to the first wall portion 112. In this embodiment, the locking groove 111 and the first mating groove 13 are located on the front and rear sides of the second mating groove 14, respectively. The locking groove 111 connects to the second mating groove 14 and is used to fasten the latching part 3021. The outer surface of the first wall part 112 includes a vertical surface 112a and an inclined surface 112b connecting the vertical surface 112a. The inclined surface 112b connects to the second wall part 113, and the first limiting part 15 connects to both the vertical surface 112a and the inclined surface 112b.

[0046] like Figure 8 As shown, the locking groove 111 includes an upper wall surface 1111 and a lower wall surface 1112 that are vertically opposite each other. The upper wall surface 1111 is connected to the vertical surface 112a, and the lower wall surface 1112 is connected to the second wall portion 113. The distance D1 between the upper surface of the second side wall 11b and the upper wall surface 1111 in the vertical direction is greater than the distance D2 between the position of the third limiting part 17 connected to the second wall portion 113 and the lower wall surface 1112. The position of the third limiting part 17 connected to the second wall portion 113 in the vertical direction is located below the lower wall surface 1112. In other embodiments, such as Figure 10 As shown, the position where the third limiting part 17 connects to the second wall part 113 along the vertical direction can also be flush with the lower wall surface 1112.

[0047] In summary, the electrical connector 100 of this utility model has the following advantages:

[0048] 1. At least one first limiting part 15 protrudes outward from the side wall 11. The first limiting part 15 is located on at least one side of the upper and lower sides of the panel 200 and is used to be stopped by the panel 200 from moving upward or / and downward. Since the side wall 11 on the side of the second docking groove 14 is provided with a locking groove 111, the strength of the side wall 11 is relatively weak. As a result, when the first limiting part 15 moves in the vertical direction and is subjected to the holding force of the panel 200, the side wall 11 is easy to deform. By protruding at least one second limiting part 16 inward from the side wall 11, and at least part of the first limiting part 15 and the second limiting part 16 are aligned in the front-back direction, the strength of the side wall 11 is increased, so that when the first limiting part 15 is stopped by the panel 200 from moving upward or / and downward, the side wall 11 is not easy to deform. At the same time, the second limiting part 16 is located on at least one side of the front and back sides of the first docking groove 13 and is used to stop the docking body 301 from moving.

[0049] 2. Because a locking groove 111 is provided between the two first limiting parts 15 and the first wall part 112, the strength of the first wall part 112 is relatively weak. As a result, when the first limiting part 15 moves in the vertical direction and is subjected to the holding force of the panel 200, the first wall part 112 is easy to deform. Therefore, the thickness of the first wall part 112 in the front-back direction is greater than the thickness of the second wall part 113, which helps to increase the strength of the first wall part 112. The lower surface of the first limiting part 15 is located at the connection between the first wall part 112 and the second wall part 113. Since the thickness of the second wall part 113 is smaller, the second wall part 113 provides clearance space for the panel 200, which helps to stabilize the contact between the panel 200 and the first limiting part 15.

[0050] 3. A third limiting part 17 protrudes outward from the side wall 11. The width of the third limiting part 17 in the left-right direction is greater than the width of the locking groove 111. This not only helps to increase the strength of the third limiting part 17 itself and ensure the stability of the contact panel 200, but also reduces the deformation of the second wall part 113 between the locking groove 111 and the third limiting part 17.

[0051] 4. Since the first wall portion 112 is often subjected to stress and the thicknesses of the first wall portion 112 and the second wall portion 113 are different, by adding an inclined surface 112b for transition, the stress is dispersed and it is not easy to break.

[0052] 5. At least one third limiting part 17 protrudes outward from the side wall 11. The third limiting part 17 is located on one of the upper and lower sides of the locking groove 111. The first limiting part 15 and the third limiting part 17 are located on the upper and lower sides of the panel 200, respectively, and the first limiting part 15 and the third limiting part 17 are misaligned in the vertical direction. The third limiting part 17 is used to be stopped by the panel 200 from moving upward or downward. Since the locking groove 111 is provided on the side wall 11 on the side of the second docking groove 14, the strength of the side wall 11 is relatively weak. As a result, when the third limiting part 17 is subjected to the holding force of the panel 200 moving in the vertical direction, the side wall 11 is easy to deform. By protruding at least one second limiting part 16 inward from the side wall 11, and aligning at least part of the third limiting part 17 with the second limiting part 16 in the front-back direction, the strength of the side wall 11 is increased, so that when the third limiting part 17 is stopped by the panel 200 from moving upward or downward, the side wall 11 is not easily deformed.

[0053] 6. A third limiting part 17 protrudes outward from the side wall 11. The width of the third limiting part 17 in the left-right direction is greater than the width of the locking groove 111. This not only helps to increase the strength of the third limiting part 17 itself and ensure the stability of the contact panel 200, but also reduces the deformation of the side wall 11 part between the locking groove 111 and the third limiting part 17.

[0054] 7. The locking groove 111 extends through the front-to-back direction, making the side wall 11 relatively weak. Since the width of the third limiting part 17 in the left-to-right direction is greater than the width of the locking groove 111, the strength of the third limiting part 17 itself can be increased, reducing the deformation of the side wall 11 portion between the locking groove 111 and the third limiting part 17. Therefore, the distance between the upper surface of the side wall 11 and the upper wall surface 1111 in the up-down direction is set to be greater than the distance between the position where the third limiting part 17 connects to the side wall 11 and the lower wall surface 1112. While ensuring that the height of the locking groove 111 meets the requirements for the latching part 3021 to engage, the strength of the portion between the upper surface of the side wall 11 and the upper wall surface 1111 is increased, preventing damage and deformation of the portion between the upper surface of the side wall 11 and the upper wall surface 1111 under the action of external force.

[0055] 8. While ensuring that the height of the locking groove 111 meets the requirements of the latching part 3021 for fastening, the distance between the upper surface of the side wall 11 and the upper wall surface 1111 along the vertical direction is maximized, thereby increasing the strength of the part between the upper surface of the side wall 11 and the upper wall surface 1111.

[0056] 9. Since the second limiting part 16 connects the end wall 12 and the side wall 11, the wall thickness of the insulating body 1 at the connection of the three is large. The insulating body 1 has at least one material removal hole 18 recessed from top to bottom. The material removal hole 18 is located at the second limiting part 16 and the end wall 12, and is not located at the side wall 11. This helps to reduce the wall thickness, avoid shrinkage during injection molding, and avoid reducing the strength of the side wall 11.

[0057] 10. While the fastening part 20 of the electrical connector 100 engages with the fastening groove 201 of the panel 200, the electrical connector 100 also communicates with the latching part 3021 of the mating connector 300 through the locking groove 111, so that the electrical connector 100 and the mating connector 300 are firmly mated. The center line of the terminal groove in the front-back direction is misaligned with the latching part. Compared with the center line of the terminal groove in the front-back direction being aligned with the latching part, it can ensure that the size of the electrical connector 100 in the front-back direction is not increased, thus reducing the space occupied.

[0058] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
