[0031]
[0032] [Specific implementation method]
[0033] In order to facilitate a better understanding of the purpose, structure, characteristics and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.
[0034] For ease of understanding, the Z-axis extension direction is defined as the up-down direction (where the positive direction of the Z-axis is the upward direction), the Y-axis extension direction is defined as the left-right direction (where the positive direction of the Y-axis is the right direction), and the X-axis extension direction is defined as the front-back direction (where the positive direction of the X-axis is the forward direction).
[0035] like Figures 1 to 10 As shown, it is a related figure of the network connector 100 of the present invention, such as Figure 1 and Figure 2 As shown, a network connector 100 is mounted on a circuit board 200. The network connector 100 includes an insulating body 10. The insulating body 10 extends backward to form a shielding portion 13. The insulating body 10 is provided with a plurality of plug-in cavities 11 penetrating the front end of the insulating body 10. Each plug-in cavity 11 is provided with a plurality of receiving grooves 12. The lower surface of the receiving groove 12 is formed by a horizontal abutting surface 121 connected to a lower inclined surface 122. Two insulating seats 20 are received in the insulating body 10 and located in the plug-in cavity 11. 1, in the front-to-back direction, each insulating seat 20 has a supporting body 21, and the supporting body 21 can be divided into a front wall 212 and a rear wall 211. In the up-down direction, the front wall 212 includes a first portion 212A and a second portion 212B extending downward from the first portion 212A, and the wall thickness of the first portion 212A is greater than the wall thickness of the second portion 212B. An accommodating cavity 22 is provided between the front wall 212 and the rear wall 211. Of course, in other embodiments, only one insulating seat 20 may be provided.
[0036] like Figure 2As shown, a partition 23 extends upward to the rear wall 211, the partition 23 includes two partition ribs 231, a connecting portion 232 connects the two partition ribs 231 to form an accommodating space 233 with an opening 2331 facing upward, and the shielding portion 13 overlaps the partition 23 and covers the opening 2331. In the up-down direction, the distance from the upper surface of the connecting portion 232 to the lower surface of the connecting portion 232 is equal to or greater than the distance from the upper surface of the connecting portion 232 to the lower surface of the partition rib 231. Of course, in other embodiments, the partition 23 may only include two partition ribs 231, and does not include the connecting portion 232.
[0037] like Figure 3 , Figure 4 and Figure 7 As shown, the first terminal 30 is a power terminal, and the second terminal 40 can be a power terminal, a signal terminal, a transfer terminal, or a detection terminal, etc., wherein the voltage of the first terminal 30 is greater than the voltage of the second terminal 40. The first terminal 30 and the second terminal 40 are both fixed to the rear wall 211, each first terminal 30 has a first welding portion 31 and a first fixing portion 32, and each second terminal 40 has a second welding portion 41 and a second fixing portion 42, wherein the first welding portion 31 and the second welding portion 41 are arranged side by side left and right, and the partition rib 231 is located between the first welding portion 31 and the second welding portion 41. In the front-to-back direction, each partition rib 231 exceeds the first welding portion 31 and the second welding portion 41 forward and backward to isolate the first welding portion 31 from the second welding portion 41, and the distance from the rear surface of the connecting portion 232 to the rear wall 211 is greater than the maximum distance from the first terminal 30 to the rear wall 211 and greater than the maximum distance from the second terminal 40 to the rear wall 211, the first welding portion 31 is located in the accommodating space 233 and exposed in the opening 2331, and the first fixing portion 32 and the second fixing portion 42 both extend downward through the circuit board 200.
[0038] like Figure 2 and Figure 8As shown, each docking terminal 50 has a fixing portion 52 extending toward the plug-in cavity 11 and bending inward to form a contact portion 51 extending into the plug-in cavity 11. In the left-right direction, the width of the contact portion 51 gradually decreases along the front-back direction. The contact portion 51 has a free end 511 with the smallest width. The lower surface of the free end 511 overlaps the abutting surface 121, wherein the free end 511 is provided with an inclined surface 512. In addition, one end of the fixing portion 52 away from the contact portion 51 extends downward to form a vertical portion 53. The vertical portion 53 extends backward to form a bridging portion 54, which connects the welding foot 55. In the up and down directions, the highest point of the welding foot 55 is lower than the vertical portion 53. Specifically, the vertical portion 53 and the bridging portion 54 are fixed to the first portion 212A. Since the wall thickness of the first portion 212A is greater than the wall thickness of the second portion 212B, the stability of the fixing of the docking terminal 50 is enhanced, and the docking terminal 50 will not break due to the inability of the first portion 212A to support the vertical portion 53 when fixed due to the thin wall.
[0039] like Figures 5 and 6 As shown, two built-in circuit boards 60 are respectively installed on the corresponding supporting body 21, and the electronic components (not shown) installed on the lower surface of the built-in circuit board 60 are accommodated in the accommodating cavity 22. The welding feet 55, the first welding part 31 and the second welding part 41 all pass through the built-in circuit board 60 upwards. The built-in circuit board 60 is provided with a clearance groove 63 corresponding to the partition rib 231 for the partition rib 231 to pass upwards. In the vertical direction, the distance from the upper surface of the partition 23 to the upper surface of the built-in circuit board 60 is greater than the distance from the upper surface of the first welding part 31 to the upper surface of the built-in circuit board 60 and the distance from the upper surface of the second welding part 41 to the upper surface of the built-in circuit board 60, so as to isolate the first welding part 31 from the second welding part 41 in the vertical direction. In the front-to-back direction, the built-in circuit board 60 is provided with a straight surface 61 arranged parallel to the connecting part 232, which can avoid the straight surface 61 and the connecting part 232 from contacting in the vertical direction or the front-to-back direction, causing the built-in circuit board 60 to scrape the connecting part 232 when it is installed downward, causing the built-in circuit board 60 to wear and affect the performance of the connector.
[0040] like Fig. 9 and Fig.10 As shown, a metal shell cover is arranged on the insulating body 10, and a convex portion 62 is extended backward from the built-in circuit board 60. A notch 71 is provided in the metal shell corresponding to the convex portion 62 for the convex portion 62 to pass through. A spring piece 72 is extended from the left and right edges of the notch 71 respectively. A concave portion 621 corresponding to the spring piece 72 is provided on the left and right sides of the convex portion 62 respectively. The spring piece 72 is clamped in the concave portion 621 in the left and right directions.
[0041] When the plug is inserted, the front end of the plug pushes the contact portion 51 upward, causing the contact portion 51 to move upward. When the contact portion 51 moves upward to the maximum distance, since the free end 511 is provided with an inclined surface 512, the inclined surface 512 will upwardly abut against the insulating body 10, so that the contact portion 51 will not scratch the insulating body 10. Moreover, since the height and length of the partition portion 23 both isolate the first welding portion 31 from the second welding portion 41, although the first welding portion 31 and the second welding portion 41 are arranged side by side, the sparks generated will not affect the second terminal 40.
[0042] In summary, the network connector 100 of the present invention has the following beneficial effects:
[0043] (1) Compared with the prior art, the first welding portion 31 and the second welding portion 41 are arranged side by side on the left and right, and the partition rib 231 is located between the first welding portion 31 and the second welding portion 41. In the front-to-back direction, each partition rib 231 extends forward and backward beyond the first welding portion 31 and the second welding portion 41, isolating the first welding portion 31 from the second welding portion 41. In the top-to-bottom direction, the distance from the upper surface of the partition 23 to the upper surface of the built-in circuit board 60 is greater than the distance from the upper surface of the first welding portion 31 to the upper surface of the built-in circuit board 60 and the distance from the upper surface of the second welding portion 41 to the upper surface of the built-in circuit board 60, which can better isolate the current interference between the two and prevent the first terminal 30 from sparking and affecting the second terminal 40.
[0044] (2) A connecting portion 232 connects two partition ribs 231 in the up-down direction, and the distance from the upper surface of the connecting portion 232 to the lower surface of the connecting portion 232 is equal to or greater than the distance from the upper surface of the connecting portion 232 to the lower surface of the partition rib 231. This can prevent the partition rib 231 from breaking below or above the built-in circuit board 60 due to the action of force, thereby ensuring the structural strength of the partition 23. In addition, the distance from the rear surface of the connecting portion 232 to the rear wall 211 is greater than the maximum distance from the first terminal 30 to the rear wall 211 and greater than the maximum distance from the second terminal 40 to the rear wall 211. This also prevents the partition 23 formed by extending upward due to the thin rear wall 211 from being insufficient in structural strength and easy to break. The thickness of the connecting portion 232 is sufficient to support the structural stability of the two partition ribs 231, thereby preventing the connecting portion 232 from breaking under the action of force and affecting the isolation effect.
[0045] (3) The shielding portion 13 overlaps the partition portion 23 and covers the opening 2331 to prevent dust from entering the accommodating space 233 through the gap of the opening 2331 and contaminating the first terminal 30, thereby playing a role in preventing dust and dirt.
[0046] (4) When the plug is inserted, when the contact portion 51 moves upward to the maximum distance, since the free end 511 is provided with an inclined surface 512, the inclined surface 512 will abut upward against the insulating body 10, so that the contact portion 51 will not scratch the insulating body 10 and affect the strength of the insulating body 10.
[0047] (5) In the left-right direction, the width of the contact portion 51 gradually decreases along the front-back direction. The contact portion 51 has a free end 511 with the smallest width. The lower surface of the free end 511 overlaps the abutment surface 121. Since the width of the free end 511 is smaller than the other widths of the contact portion 51, when the plug is pulled out, the free end 511 can quickly recover its deformation and overlap the abutment surface 121, thereby preventing the contact portion 51 from tilting up and down in the free state and causing poor contact.
[0048] (6) The vertical portion 53 and the bridging portion 54 of the docking terminal 50 are fixed to the first portion 212A of the front wall 212, so that the wall thickness of the first portion 212A is greater than the wall thickness of the second portion 212B, thereby enhancing the stability of the fixation of the docking terminal 50 and preventing the first portion 212A of the docking terminal 50 from being unable to support the vertical portion 53 and breaking when the docking terminal 50 is fixed due to the thin wall of the front wall 212.
[0049] (7) In the front-to-back direction, the built-in circuit board 60 is provided with a straight surface 61 which is arranged parallel to the connecting portion 232, so as to avoid contact between the straight surface 61 and the connecting portion 232 in the up-down direction or the front-to-back direction, which would cause the built-in circuit board 60 to scrape the connecting portion 232 when installed downward, thereby causing wear of the built-in circuit board 60 and affecting the performance of the connector.
[0050] (8) The highest point of the welding foot 55 is lower than the vertical portion 53, so that the welding foot 55 can be automated, the height of the built-in circuit board 60 can be reduced, and the height of the supporting body 21 can also be reduced, which is conducive to the miniaturization of the connector.
[0051] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
