[0031] Reference Figure 2-8 As shown, a stamped shell Ethernet connector of the utility model comprises:

[0032] Insulation body 5;

[0033] The plug assembly 7 is inserted into the insulating body 5 and used for transmitting signals, and includes a connecting section 72 and a plug end;

[0034] The outer shell 6 includes: a top wall 61, a first side wall 62 radially arranged on both sides of the top wall 61, and a second side wall 63 axially arranged on the top wall 61 and close to the end of the connecting section 72, the first side wall 62 and the second side wall 63 are respectively connected to the top wall 61, and the top wall 61, the first side wall 62 and the second side wall 63 surround and cover the connecting section 72.

[0035] The utility model discloses a stamped shell Ethernet connector, in which a plug-in port 54 is provided on one side of an insulating body 5 and a plug-in space is formed, and the plug-in end is accommodated in the plug-in space, and one side of the plug-in end is defined as the front end, and one end of the connecting section 72 is defined as the rear end, the rear end of the insulating body 5 is covered on the connecting section 72, and the outer shell 6 is covered on the rear end of the insulating body 5, and the plug-in assembly 7 and the outer shell 6 respectively play the role of inner shielding and outer shielding, and the top wall 61 of the outer shell 6 covers the top of the connecting section 72, the first side wall 62 respectively covers the two radial sides of the connecting section 72, and the second side wall 63 covers the rear end portion of the connecting section 72 in the axial direction, so that the outer shell 6 and the plug-in assembly 7 form a double-layer shielding protection for the connecting part, thereby improving the shielding effect, and the structure of the outer shell 6 is easy to manufacture, and can be formed by stamping and bending, which is more environmentally friendly than the one-piece zinc alloy shell.

[0036] See also Figure 3-Figure 5 As shown, the plug-in assembly 7 includes a connecting section 72 and a plug-in section 71, the connecting section 72 is used to connect to the circuit board 4, one end of the insulating body 5 is arranged between the connecting section 72 and the outer shell 6, the connecting section 72 is arranged inside the insulating body 5 and is positioned and connected to the insulating body 5, the connecting section 72 and the plug-in end are coaxially arranged, the connecting section 72 is downwardly connected to the circuit board 4, and the inner and outer sides of the rear end wall of the insulating body 5 are respectively attached to the connecting section 72 and the second wall.

[0037] See also Figure 5 As shown, the top wall 61 is bent toward the connecting section 72 to form a first connecting portion 66, and the insulating body 5 is provided with a first slot 51 adapted to the first connecting portion 66. The first connecting portion 66 is bent downward from the top wall 61 to abut against the connecting section 72, and is conductively connected by spot welding, thereby increasing the shielding effect of the inner shell 73 and the outer shell 6, and at the same time playing a retaining role to increase the structural strength.

[0038] See also Figure 4-Figure 7As shown, a first limiting assembly is arranged between the insulating body 5 and the top wall 61, which includes: a first protrusion 55 extending outward from the end of the insulating body 5, and a second protrusion 56 extending from the end of the first protrusion 55 in a direction perpendicular to the axis of the first protrusion 55. The first connecting portion 66 is clamped between the insulating body 5 and the second protrusion 56 and is located in the first groove body 51. In this embodiment, the number of the second protrusions 56 is two, and they extend radially toward both sides of the connecting section 72, thereby limiting the axial direction of the outer shell 6 through the first connecting portion 66.

[0039] Continue to see Figure 4-Figure 7 As shown, a second limiting assembly is arranged between the first side wall 62 and the insulating body 5, which includes: a third protrusion 52 arranged on the insulating body 5, and a second groove body 69 opened on the first side wall 62 and capable of being snapped onto the third protrusion 52. The third protrusion 52 performs two groups of vertical limiting on the first side wall 62 and the outer shell 6. Specifically, the material of the insulating body 5 is an elastic insulating material, which can be optionally plastic. The third protrusion 52 is integrally formed on the insulating body 5, and has a guiding slope on the top, and the bottom is perpendicular to the insulating body 5. The guiding slope gradually narrows from bottom to top, so that when the outer shell 6 is crimped and installed, the first side wall 62 crimps the third protrusion 52 to deform. When the second side wall 63 slides until the third protrusion 52 enters the second groove body 69, the third protrusion 52 is reset and snapped with the lower inner wall of the second groove body 69 to form an undercut, thereby improving the pull-out strength of the first side wall 62 and the outer shell 6.

[0040] Please continue to see Figure 4-Figure 7 As shown, a third limiting assembly is provided between the second side wall 63 and the first side wall 62, which includes: a first bending portion 64 formed by bending the two sides of the second side wall 63 toward the first side wall 62 and having a third groove body 67, and a fourth convex body 68 bent by the first side wall 62 and adapted to be snapped into the third groove body 67. The second side wall 63 is formed by bending the front end of the top wall 61 downward, and is connected to the top wall 61 by bending the third connecting portion 9. The third connecting portion 9 avoids the left and right sides of the top wall 61 to avoid stress concentration. The first bending portion 64 is bent backward and forward from the rear end of the connecting section 72 and fits the first side wall 62. On the one hand, the second side wall 63 can provide support force for the plugging of the connector, and the support strength of the second side wall 63 is improved by connecting the first bending portion 64 and the first side wall 62. The first bending portion 64 has a third groove 67, and a part of the wall of the first side wall 62 is bent outward to form a fourth convex body 68 and is adapted to the third groove 67. The end of the fourth convex body 68 abuts against the front inner wall of the third groove 67, thereby providing support for the backward plugging force of the first side wall 62 and the outer shell 6; on the other hand, the first bending portion 64 is covered at the interface between the second side wall 63 and the first side wall 62, and the vertical interface between the second side wall 63 and the first side wall 62 is shielded.

[0041] The first connecting portion 66, the second connecting portion 65, the first limiting component, the second limiting component and the third limiting component are arranged to cooperate with each other to fix the outer shell 6 to improve the structural strength, so that the outer shell 6, the insulating body 5 and the inner shell 73 are tightly connected. In some embodiments, the connector is a single-cell structure or a multi-cell structure, that is, the connector has a single or multiple plug-in components 7, such as the number of plug-in components 7 can be one, two, four or more. When the number of plug-in components 7 is two or more, it can be selected as an even number and symmetrically arranged. The symmetrical arrangement enables the plug-in components 7 to be subjected to a relatively uniform and balanced force during insertion. The overall strength of the connector is high, and the possibility of connection failure caused by unbalanced force can be reduced to a minimum. In addition, the insulating body is provided with a spacing portion extending between the plug-in components 7, which is used to limit and fix each plug-in component 7. In some embodiments, the plug-in port 54 can be filled with an insulating colloid, which can be silica gel. The colloid is filled between the inner shell 73 and the insulating body 5 and / or between the plug core 75 and the inner shell 73 to improve the waterproof grade of the connector and improve the waterproof and dustproof effect of the connector.

[0042] See also Figure 4 , Figure 8 As shown, the plug-in assembly 7 includes an inner shell 73, a core 75 and a terminal 74. The connecting section 72 of the inner shell 73 is covered by an insulating body 5 and an outer shell in sequence. The core 75 is embedded in the inner wall of the inner shell 73. The terminal 74 is penetrated by the core 75. One end of the terminal 74 passes through the core 75 and the other end is used to be connected to the circuit board 4. The inner shell 73 and the outer shell 6 are both metal shells, which provide shielding and protect the structural structure. The outer shell 6 can be made of any material of brass, stainless steel, or stainless steel plated with copper.

[0043] The circuit board 4 is provided with a plurality of through holes, and the outer shell 6 and the inner shell 73 are respectively provided with pins adapted to the through holes. The through holes of the circuit board 4 and the pins of the outer shell 6 and the inner shell 73 are arranged correspondingly. The outer shell 6 and the inner shell 73 have the same number of pins and are inserted into the same through hole at corresponding positions, and the pins are connected to the pads on the circuit board 4 through solder.

[0044] See also Figure 5As shown, the second side wall 63 is bent toward the inner shell 73 to form a second connecting portion 65, and the second connecting portion 65 and the first connecting portion 66 are respectively connected to the two sides of the shell, and the second connecting portion 65 is bent inward from the end of the second side wall 63, and is specifically divided into an upper second bending portion 651 and a connecting third bending portion 652, and the second bending portion 651 is bent upward from the end of the second side wall 63 inside the outer shell 6, and the second bending portion 651 fits the second side wall 63 and corresponds to the rear port of the connecting section 72, so as to increase the equivalent shielding thickness of the rear opening of the connector, and at the same time, the second shell is used to connect the third bending portion 652, and the third bending portion 652 is connected to the end of the second bending portion 651 and connected to the inside of the inner shell 73, and the third bending portion 652 is connected to the top wall 61 by spot welding, so as to further increase the connection strength and shielding effect.

[0045] See also Figure 7 As shown, the outer shell 6 and the inner shell 73 have a protrusion extending toward the side close to the circuit board 4, and the protrusion is provided with a groove, and the groove corresponds to the position to be welded of the circuit board 4. When the connector is welded to the circuit board 4, the protrusion corresponds to the position to be welded corresponding to the circuit board 4, and the solder paste during soldering can climb along the protrusion and enter the groove, thereby increasing the contact area between the welding position and the groove, improving the connection strength between the connector and the circuit board 4, and making the pull-out strength of the connector reach more than 110N.

[0046] See also Figure 6 As shown, further, the insulating body 5 is also provided with a plurality of guide grooves 53 along the vertical direction, and the number, size and position of the guide grooves 53 correspond to the pins 8 of the outer shell 6, so that the pins 8 of the outer shell 6 can slide downward along the guide grooves 53, thereby facilitating the installation of the outer shell 6 onto the insulating body 5.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
