[0036] like Figure 1 As shown, the terminal connector in the prior art consists of a terminal 2 and a base body 1, wherein a socket 11 is provided on the base body 1, and the terminal 2 passes through the socket 11 to be inserted into the base body 1. To meet the use requirements, for some terminal connectors, one end of the terminal 2 needs to be bent and form a bending portion 22. However, since the socket 11 on the base body 1 in the prior art is generally in the shape of a slit, the slit-shaped socket 11 can only allow the straight terminal 2 to pass through. Therefore, the prior art generally adopts a method of first inserting the terminal 2 into the base body 1 and then bending the end of the terminal 2 to form the bending portion 22 to manufacture the terminal connector. However, bending the end of the terminal 2 after assembling the base body 1 and the terminal 2 will damage the plating layer electroplated on the terminal 2, thereby resulting in poor contact of the subsequent terminal 2, thereby affecting the use effect of the terminal connector.

[0037] To solve the above problems, please refer to Figures 2 to 7The present embodiment provides a terminal connector, which also includes a base body 1 and a terminal 2. The base body 1 is provided with a plug hole 11. In particular, the plug hole 11 provided on the base body 1 includes a first hole portion 111 and a second hole portion 112. The first hole portion 111 and the second hole portion 112 are cross-arranged. For example, in the present embodiment, the first hole portion 111 and the second hole portion 112 are cross-arranged. The terminal 2 includes a body 21 and a bent portion 22 disposed at one end of the body 21 and bent. The body 21 is penetrated and installed in the first hole portion 111. The projection of the bent portion 22 along the opening direction of the plug hole 11 is located within the contour range of the second hole portion 112.

[0038] That is, in this embodiment, the socket 11 on the seat body 1 is composed of a first hole portion 111 and a second hole portion 112, wherein the body 21 of the terminal 2 can pass through the first hole portion 111, so that the terminal 2 can be inserted into the seat body 1, and the second hole portion 112 can provide a passage for the bending portion 22 to pass through the seat body 1.

[0039] From the above, since the seat body 1 is provided with a second hole portion 112 for the bending portion 22 to pass through, the present embodiment can first bend one end of the terminal 2 to form the bending portion 22, and then electroplate the terminal 2, and then insert the terminal 2 into the seat body 1 to assemble a terminal connector. The entire assembly process will not cause damage to the plating on the terminal 2, thereby avoiding poor contact of the subsequent terminal 2, and further avoiding affecting the use effect of the terminal connector.

[0040] Based on the above, this embodiment further provides a method for manufacturing a terminal connector, the method for manufacturing a terminal connector comprising:

[0041] The seat body 1 is provided with a first hole portion 111 and a second hole portion 112 which intersect each other;

[0042] After the terminal 2 is processed into a main body 21 and a bent portion 22 disposed at one end of the main body 21 and bent, the terminal 2 is electroplated;

[0043] The bent portion 22 of the terminal 2 is passed through the second hole 112 , so that the body 21 is installed in the first hole 111 .

[0044] It can be understood that the terminal connector includes a plurality of terminals 2 , and correspondingly, a plurality of insertion holes 11 are provided on the base body 1 , and the plurality of terminals 2 pass through the plurality of insertion holes 11 one by one, and are thus inserted on the base body 1 together.

[0045] Furthermore, in this embodiment, a sealing groove 12 is also provided on the base body 1, the plug hole 11 is connected with the sealing groove 12, the terminal 2 is inserted into the sealing groove 12 and the plug hole 11, and the sealing groove 12 is filled with sealant 121. The sealant 121 plays a sealing role, thereby isolating two adjacent terminals 2 from each other to avoid short circuit problems in the terminal connector due to the entry of foreign matter, thereby further avoiding affecting the use effect of the terminal connector.

[0046] From the above, the manufacturing method of the terminal connector also includes:

[0047] The sealing groove 12 is filled with a sealant 121 .

[0048] Specifically, after the bent portion 22 of the terminal 2 passes through the second hole 112 so that the body 21 is installed in the first hole 111 , the sealing adhesive 121 is filled into the sealing groove 12 .

[0049] Based on the content mentioned above, in this embodiment, a first boss 211 and a second boss 212 are respectively provided on both sides of the main body 21, and the first boss 211 and the second boss 212 are respectively abutted against two opposite inner walls of the second hole portion 112, so that the terminal 2 can be stably supported in the socket 11 to avoid shaking of the terminal 2 inserted on the seat body 1, thereby further avoiding affecting the use effect of the terminal connector.

[0050] Based on the above, the first boss 211 and the second boss 212 cooperate to seal the second hole portion 112. Specifically, the portion of the second hole portion 112 located on one side of the first hole portion 111 is sealed by the first boss 211, and the portion of the second hole portion 112 located on the other side of the first hole portion 111 is sealed by the second boss 212, thereby preventing the glue from leaking through the jack 11 when pouring glue into the sealing groove 12.

[0051] It is worth noting that, in the present embodiment, part of the plate surface of the terminal 2 is bent to form the first boss 211 and the second boss 212. Exemplarily, the present embodiment forms the first boss 211 and the second boss 212 on the terminal 2 by stamping, thereby simplifying the manufacturing process of the terminal 2 and saving the manufacturing cost of the terminal 2.

[0052] It is also worth noting that the terminal 2 is a plastic part, and the body 21 is provided with a first groove 213 and a second groove 214 on both sides of the bending direction of the bending portion 22, wherein the first groove 213 is provided on the same side as the first boss 211, and the second groove 214 is provided on the same side as the second boss 212, and the second boss 212 is located on the other side of the first groove 213 along the bending direction of the bending portion 22, and the first boss 211 is located on the other side of the second groove 214 along the bending direction of the bending portion 22, that is, in this embodiment, the first groove 213 is provided correspondingly to the second boss 212, and the first groove 213 is recessed toward the second boss 212, and the second groove 214 is provided correspondingly to the first boss 211, and the second groove 214 is recessed toward the first boss 211, so that when the terminal 2 is manufactured, the first boss 21 can be made The distance between the side away from the second boss 212 and the side away from the first boss 211 of the second boss 212 is slightly larger than the size of the second hole 112. When the terminal 2 is inserted, since the first boss 211 is correspondingly provided with the second groove 214 and the second boss 212 is correspondingly provided with the first groove 213, the first boss 211 can be deformed toward the side close to the second boss 212, and the second boss 212 can be deformed toward the side close to the first boss 211, so that the first boss 211 and the second boss 212 can be inserted into the second hole 112. After the first boss 211 and the second boss 212 are inserted into the second hole 112, the first boss 211 and the second boss 212 can be stably supported in the second hole 112, so that the second hole 112 can be more fully blocked.

[0053] It can be understood that since the first boss 211 and the second boss 212 are formed on the terminal 2 by stamping in this embodiment, a second groove 214 is formed on the terminal 2 while the first boss 211 is stamped. Correspondingly, a first groove 213 is formed on the terminal 2 while the second boss 212 is stamped.

[0054] In addition, a protrusion 215 is provided on the body 21 , and a third groove 1111 is provided on the hole wall of the first hole portion 111 . The protrusion 215 is accommodated in the third groove 1111 , so that the seat body 1 can stop the terminal 2 and prevent the terminal 2 from escaping from the seat body 1 .

[0055] Among them, a first inclined surface 2151 is formed on the side of the protrusion 215 facing the bending portion 22, and a second inclined surface 11111 is formed on the groove wall of the third groove 1111. The connection between the first inclined surface 2151 and the main body 21 is arranged close to the bending portion 22, and the connection between the first inclined surface 2151 and the side of the protrusion 215 away from the main body 21 is arranged away from the bending portion 22. The first inclined surface 2151 is in contact with the second inclined surface 11111, so that the seat body 1 can fully stop the terminal 2.

[0056] It is worth noting that the main body 21 is provided with protrusions 215 on both sides in a direction perpendicular to the bending direction of the bending portion 22 , so that the seat body 1 can more fully stop the terminal 2 .

[0057] Furthermore, two or more protrusions 215 are provided on both sides of the body 21 in a direction perpendicular to the bending direction of the bending portion 22 , thereby further enabling the seat body 1 to more fully stop the terminal 2 .

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
