[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In this invention, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0040] This invention improves the position and connection relationship of the auxiliary solder feet of the electrical connector, and designs a connector that is easy to assemble, reduces the number of auxiliary solder feet, and improves the connection reliability between the electrical connector and the PCB board.

[0041] Example 1

[0042] See Figures 1 to 4 As shown, an electrical connector with auxiliary solder pads includes a connector housing 1.

[0043] The insertion slot 10 is located at the bottom of the front end of the insertion housing; the insertion slot is machined from the front end to the rear end of the insertion housing.

[0044] The slot 11 is located on the bottom surface of the plug-in housing and communicates with the plug-in slot. The slot is also machined from the front end to the rear end of the plug-in housing.

[0045] Auxiliary solder feet 2 are inserted into and fitted within the insertion slot and the groove opening. The auxiliary solder feet 2 include a connecting part 20 and a welding part 21. The connecting part 20 is inserted into and fitted within the insertion slot 10, and the welding part 21 fits into the groove opening and protrudes from the bottom surface of the insertion housing 1. The welding part protrudes from the bottom surface of the insertion housing and is inserted into a hole on the PCB board. The welding part is fixed to the PCB board by welding, thereby fixing the electrical connector to the PCB board. The connecting part is inserted into and fitted within the insertion slot, which realizes the connection between the auxiliary solder feet and the insertion housing. Preferably, the insertion slot 10 is located on the center line of the bottom surface of the insertion housing 1. In this embodiment, only one auxiliary solder foot needs to be set on the insertion housing, and it is located on the center line of the bottom surface of the insertion housing. On the one hand, the number of auxiliary solder feet is reduced, the structure of the insertion housing is simplified, and the manufacturing difficulty is reduced. On the other hand, the connection between the auxiliary solder foot on the center line and the copper part at the tail of the insertion housing and the PCB board forms an isosceles triangle, ensuring the reliability of the connection between the insertion housing and the PCB board.

[0046] Furthermore, in this embodiment, the width of the slot 11 is smaller than the width of the insertion slot 10. The connecting part 20 is connected in the insertion slot and cannot be dislodged from the direction of extension towards the welding part, which ensures the reliability of the connection between the auxiliary welding foot and the insertion housing, and also ensures the holding force between the insertion housing and the PCB board, thus meeting the usage requirements.

[0047] Specifically, in this embodiment, the cross-section of the insertion slot 10 is square, the connecting part 20 is square, and the width of the connecting part is greater than the width of the slot. When the connecting part of the auxiliary welding foot is inserted into the insertion slot, since the width of the connecting part is greater than the width of the slot, the auxiliary welding cannot be removed from the insertion slot along the length direction of the auxiliary welding foot. In this embodiment, the connecting part 20 is a square plate, and the welding part 21 is fixedly connected to the center line of the length direction of the plate. The welding part 21 includes an end 211 and a pair of welding feet 210 symmetrically arranged on the end, with a gap between the two welding feet.

[0048] Example 2

[0049] Building upon implementation 1, this embodiment makes further improvements, specifically modifying the shape of the connecting portion. See [link to implementation 1]. Figure 5As shown, the connecting part 20 includes a first connecting piece 201 and a second connecting piece 202. The first connecting piece 201 and the second connecting piece 202 are connected to the end of the welding part 21, and the first connecting piece 201 and the second connecting piece 202 are respectively located on both sides of the welding part. The included angle between the first connecting piece 201 and the second connecting piece 202 and the welding part is 90°. The first connecting piece and the second connecting piece are in the same plane. During assembly, the first connecting piece and the second connecting piece are inserted into the insertion groove, and the lower surfaces of the first connecting piece and the second connecting piece are respectively pressed against the surfaces of the insertion groove located on both sides of the groove. This allows the shells on both sides of the groove to be subjected to force simultaneously, ensuring the balance of force and also ensuring the structural strength of the insertion groove. This prevents the shells at the insertion groove from being damaged by tension, thus improving the service life of the electrical connector.

[0050] Example 3

[0051] Based on Example 1, this example makes further improvements. The shapes of the insertion slot and the connecting part are modified in this example. (See attached image.) Figure 6 and Figure 7 As shown, in this embodiment, the cross-section of the insertion slot 10 is triangular, the connecting part 20 is triangular, and the widest part of the connecting part 20 is larger than the width of the slot 11.

[0052] Example 4

[0053] This embodiment provides another structural approach; see [link to previous section]. Figures 8 to 10 As shown, in this embodiment, the length of the insertion slot 10 is greater than the length of the slot opening 11, and the length of the connecting part 20 is greater than the length of the welding part 21. In this embodiment, the connecting part is inserted into the insertion slot, and the welding part is fitted into the slot opening. Since the length of the insertion slot is greater than the length of the slot opening, a portion of the insertion slot is located inside the insertion housing and is not connected to the slot opening. Therefore, the connecting part located in this portion of the insertion slot cannot be dislodged from the slot opening. Furthermore, since the length of the connecting part is greater than the length of the welding part, when the welding part is inserted into the slot opening, a portion of the connecting part is inserted into the insertion slot located inside the insertion housing, thereby achieving a fixed connection and ensuring that the auxiliary welding foot will not dislodge from its connection with the insertion housing.

[0054] For details, see Figure 8 and Figure 10As shown, in this embodiment, the width of the insertion groove 10 is equal to the width of the slot 11, but the length of the insertion groove 10 is greater than the length of the slot 11. The thickness 21 of the connecting part 20 and the welding part of the auxiliary welding foot 2 is the same, and the thickness of the insertion groove is equal to the thickness of the connecting part. The length of the connecting part 20 is greater than the length of the welding part 21. With the design of equal width, the dimensions between the insertion groove and the connecting part, and between the slot and the welding part, are perfectly matched, and the connection between the two is reliable and stable. Moreover, the thickness of the two is equal, which is beneficial to improving the thickness of the auxiliary welding foot, so that the structural strength of the auxiliary welding foot can meet the requirements of use. In this embodiment, the thickness of the auxiliary welding foot is 0.6±0.02mm.

[0055] To improve the reliability of the connection between the auxiliary welding foot and the insertion slot, at least one hook 203 is provided on the surface of the connecting part 20 located on one side of the welding part 21. The hook 203 abuts against the wall of the insertion slot to form a locking relationship. The hook protrudes from the surface of the connecting part. When the connecting part and the insertion slot are assembled, the hook will form an interference fit with the wall of the insertion slot, and the end of the hook will be embedded in the wall of the insertion slot, which plays a role in preventing the auxiliary welding foot from coming out of the insertion slot.

[0056] In summary, this utility model has the following beneficial effects:

[0057] 1. This utility model improves the structure of the electrical connector by moving the auxiliary solder feet to the front end of the electrical connector housing. On the one hand, it reduces the number of auxiliary solder feet, which simplifies the structure of the electrical connector housing and facilitates manufacturing. On the other hand, it changes the position of the auxiliary solder feet on the electrical connector housing, thereby improving the connection reliability between the front end of the electrical connector housing and the PCB board.

[0058] 2. This utility model designs a new connection structure and connection method between the auxiliary solder foot and the electrical connector housing. The auxiliary solder foot is connected to the electrical connector housing by plugging in, which facilitates the assembly of the auxiliary solder foot and the electrical connector housing. After assembly, the connection between the auxiliary solder foot and the electrical connector housing is reliable, and it is not easy for the connection between the two to fail due to damage to the electrical connector housing, thus improving the service life of the electrical connector.

[0059] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
