[0046] The present invention will be described in detail below with reference to the accompanying drawings:

[0047] Example 1:

[0048] See also Figures 1 to 8 , which is a wire terminal 101 provided by the present invention. The wire terminal 101 is composed of a wire 200 (below Figure 9 The wire terminal 101 includes a plug-in free end 10, an intermediate connecting portion 30, and a retaining tail 50. The plug-in free end 10, the intermediate connecting portion 30, and the retaining tail 50 are connected end to end in sequence.

[0049] The plug-in free end 10 is used to achieve plug-in connection. For example, the plug-in free end 10 is used to guide the wire terminal 101 to achieve plug-in connection with a matching component such as a housing, a connector, or a socket. In other words, the plug-in free end 10 is used to guide the wire terminal 101 to achieve corresponding plug-in connection.

[0050] The specific shape and structure of the plug-in free end 10 are selected as needed. In this embodiment, to facilitate plug-in connection, the plug-in free end 10 includes a plug-in connector 12 and a support portion 14. The support portion 14 connects the plug-in connector 12 and the intermediate connecting portion 30, respectively. The plug-in connector 12 has smaller radial and / or lateral dimensions than the support portion 14. In this embodiment, to facilitate processing and ease plug-in connection, the plug-in connector 12 and the support portion 14 are coaxially arranged. The plug-in connector 12 has a smaller cross-sectional area than the support portion 14. More specifically, the plug-in connector 12 is generally conical. The plug-in connector 12 can be formed by stamping and / or cutting. The specific shape and structure of the support portion 14 are sufficient as long as they can connect the plug-in connector 12 and the intermediate connecting portion 30. To streamline the manufacturing process, in this embodiment, the support portion 14 is a length of wire. In other words, the support portion 14 is a partial-length, machining-free structure. More specifically, the support portion 14 has the same radial and transverse dimensions as the wire rod. That is, the support portion 14 is a portion of the unprocessed wire rod. The longitudinal length of the support portion 14 is selected according to needs.

[0051] The intermediate connecting portion 30 extends continuously from the rear end of the free plug end 10. The intermediate connecting portion 30 is used for contact electrical connection. That is, the intermediate connecting portion 30 serves as a contact portion to directly achieve electrical connection. To improve electrical connection performance, the intermediate connecting portion 30 has larger lateral and / or radial dimensions than the free plug end 10. To further facilitate a stable electrical connection of the wire terminal 101, the intermediate connecting portion 30 utilizes a compliant electrical connection structure. Those skilled in the art will appreciate that the specific specifications, type, and shape of the compliant electrical connection structure employed by the intermediate connecting portion 30 are selected based on application requirements. The side walls of the intermediate connecting portion 30 protrude laterally relative to the free plug end 10. That is, the intermediate connecting portion 30 has larger lateral dimensions than the free plug end 10. It is understood that, unless otherwise specified, comparisons of relevant dimensions in this disclosure refer to the maximum dimension of the structure in that direction, i.e., the most protruding portion.

[0052] The retaining tail 50 is disposed on the intermediate connecting portion 30. Specifically, the retaining tail 50 is connected to the longitudinal tail end of the intermediate connecting portion 30. The maximum transverse dimensions of the retaining tail 50 are both greater than the maximum transverse dimensions of the intermediate connecting portion 30 and the plug-in free end 10. In other words, the retaining tail 50 is disposed to protrude transversely relative to both the intermediate connecting portion 30 and the plug-in free end 10. As an embodiment, the retaining tail 50 can achieve longitudinal blocking cooperation with a corresponding mating connector, thereby preventing the wire terminal 101 from being excessively plugged in along its longitudinal direction and damaging the corresponding structure.

[0053] The specific shape and structure of the retaining tail 50 only need to be configured to have a maximum lateral dimension greater than that of the intermediate connecting portion 30 and the plug-in free end 10, as described above. In this embodiment, to facilitate manufacturing, streamline the process, and conserve materials, the retaining tail 50 is a stamped structure. Furthermore, the retaining tail 50 includes shoulders 52, 52b. The shoulders 52, 52b are disposed to protrude laterally from one or both sides of the plug-in free end 10 and the intermediate connecting portion 30. There can be only one shoulder 52, 52b. In this case, one shoulder 52, 52b protrudes laterally from one side of the plug-in free end 10 and the intermediate connecting portion 30. In this embodiment, a pair of shoulders 52, 52b facilitates balanced pressure application by external press-fitting equipment, thereby improving manufacturing quality. Furthermore, the pair of shoulders 52, 52b provides stable positioning for the injection mold when the wire terminal 101 is used as an insert in an embedded injection molded part.

[0054] In this embodiment, in order to ensure that the retaining tail 50 is subjected to balanced force and improves stability, two shoulders 52 and 52b are provided. Specifically, the two shoulders 52 and 52b are symmetrically arranged. In this case, the two shoulders 52 and 52b are respectively arranged to protrude laterally relative to the sides of the intermediate connecting portion 30 and the plug-in free end 10. In other words, the shoulders 52 and 52b are arranged to protrude laterally relative to the side walls of the intermediate connecting portion 30 and the plug-in free end 10 on the same side. In other words, the retaining tail 50 forms a structure with the largest lateral dimension on the wire terminal 101 by providing the shoulders 52 and 52b.

[0055] Accordingly, in order to facilitate manufacturing, streamline the process and save materials, the shoulders 52 and 52b are stamped structures. That is, by applying a stamping process to the wire, the material is deformed and flowed, thereby forming the shoulders 52 and 52b on the wire. The specific shape of the shoulders 52 and 52b only needs to be larger than the maximum transverse dimension of the plug-in free end 10 and the intermediate connecting portion 30. Specifically, as Figure 3As shown, the transverse dimensions (i.e., width W) of the shoulders 52 and 52b are both larger than the transverse dimensions of the intermediate connecting portion 30 (the width of the intermediate connecting portion 30 is W2) and the plug-in free end 10. In this embodiment, the shoulders 52 and 52b are formed into regular planes by stamping. That is, the upper and lower surfaces of the shoulders 52 and 52b are both planes. An end face 521 is provided at the front end of the shoulders 52 and 52b. The end face 521 is used to achieve longitudinal blocking cooperation with the mating connector. In order to facilitate the mating assembly of the wire terminal 101 and provide feedback force for assembly into place when mating with the mating component, the end face 521 extends obliquely from the intermediate connecting portion 30. The end face 521 extends obliquely to a maximum transverse dimension that is larger than the intermediate connecting portion 30. That is, the end face 521 extends obliquely outward. The end face 521 can be a conical surface. Accordingly, the end surface 521 extends obliquely and rearwardly in the opposite direction of the insertion direction of the wire terminal 101. This allows the material of the retaining tail 50 of the wire terminal 101 to be squeezed as far as possible in the transverse direction, so that the end surface 521 and the shoulders 52 and 52b have the largest possible transverse dimensions, thereby improving stability and general performance. In this embodiment, the end surface 521 is a flat surface.

[0056] In order to adapt to stamping manufacturing and save materials, the shoulders 52, 52b have a radial dimension smaller than the plug-in free end 10. In other words, the shoulders 52, 52b are formed by flattening a flat wire. In this embodiment, the shoulders 52, 52b are plate-shaped with uniform thickness along the radial direction.

[0057] In order to enhance the mechanical strength of the retaining tail 50, the retaining tail 50 further includes bosses 54, 54b. The bosses 54, 54b are laterally connected to the shoulders 52, 52b. That is, the shoulders 52, 52b are arranged on one side wall or both side walls of the bosses 54, 54b. The bosses 54, 54b are arranged to protrude radially relative to the shoulders 52, 52b. The bosses 54, 54b can be located only on one side of the upper surface or lower surface of the shoulders 52, 52b. In this embodiment, in order to facilitate manufacturing and ensure that the retaining tail 50 maintains balanced force, the bosses 54, 54b are provided on one side of the upper surface and the lower surface of the shoulders 52, 52b. Specifically, a pair of the bosses 54, 54b are arranged back to back and are arranged in a "cross" shape with the pair of the shoulders 52, 52b. That is, the pair of bosses 54, 54b are symmetrically arranged, and the pair of shoulders 52, 52b are symmetrically arranged. In order to adapt to stamping manufacturing, the maximum radial dimension of the pair of bosses 54, 54b is equivalent to the maximum radial dimension of the plug-in free end 10. The upper surface of the bosses 54, 54b is in the same plane as the upper surface of the support portion 14 of the plug-in free end 10. Alternatively, in this embodiment, the radial thickness of the pair of bosses 54, 54b is equivalent to the thickness of the support portion 14. That is, the bosses 54, 54b maintain the original surface of the wire and are not processed. More specifically, the bosses 54, 54b are connected to the intermediate connecting portion 30. The shape of the bosses 54, 54b is correspondingly defined by the shoulders 52, 52b formed by stamping. In this embodiment, in order to streamline the process and facilitate manufacturing, the bosses 54, 54b are rectangular cuboids. That is, the bosses 54 and 54b have uniform transverse and radial dimensions.

[0058] To streamline the manufacturing process and save materials, the wire terminal 101 is a stamped part. That is, the wire terminal 101 is formed as an integrated connection terminal by stamping wire. To enhance electrical connection performance, the wire terminal 101 is a lightweight, compliant terminal.

[0059] Example 2:

[0060] Please also refer to Figure 9 The present invention discloses a method for manufacturing the wire terminal 101 as described in the first embodiment. Specifically, the method for manufacturing the wire terminal 101 includes the following steps:

[0061] S101: Providing a wire 200, wherein the longitudinal dimension of the wire 200 is greater than or equal to the longitudinal dimension of at least one wire terminal 101. Specifically, to manufacture a different number of wire terminals 101, the length of the wire 200 can be exactly equal to the sum of the longitudinal dimensions of the wire terminals 101 to be manufactured, which is an integer multiple of the number of wire terminals 101 to be manufactured. Within a tolerance range, the length of the wire 200 can also be greater than the sum of the longitudinal dimensions of the wire terminals 101 to be manufactured, which is an integer multiple of the number of wire terminals 101 to be manufactured.

[0062] S102: forming a plug-in free end 10 on the wire. Preferably, the plug-in head 12 is formed on the wire by punching and / or cutting.

[0063] S103: The intermediate connection part 30 is formed on the wire. The shape and structure of the intermediate connection part 30 only need to be able to achieve the connection required by the specific application. Preferably, the intermediate connection part 30 can be manufactured to conform to the electrical connection structure. Preferably, in order to facilitate the electrical connection, the intermediate connection part 30 is configured to have a lateral dimension and / or radial dimension that is larger than the plug-in free end 10. Accordingly, in order to achieve a stable connection between the plug connector 12 and the intermediate connection part 30 and facilitate plug-in matching, the part of the wire between the intermediate connection part 30 and the plug connector 12 is the support part 14. That is, the support part 14 is a stamping-free structure. More specifically, the support part 14 is a stamping-free wire structure.

[0064] S104: A retaining tail portion 50 is formed on the wire, and the retaining portion 50 has a lateral dimension greater than that of the plug-in free end 10 and the intermediate connecting portion 30. The retaining portion 50 only needs to be configured to have a lateral dimension greater than that of the largest of the plug-in free end 10 and the intermediate connecting portion 30. Preferably, the retaining portion 50 is formed by stamping. More specifically, the retaining portion 50 forms a pair of shoulders 52, 52b that protrude laterally relative to the intermediate connecting portion 30 and the plug-in free end 10 through the upper and lower surfaces of the stamped portion. Preferably, the portion of the retaining portion 50 that is not stamped forms bosses 54, 54b that protrude radially relative to the shoulders 52, 52b. That is, the bosses 54, 54b are a stamping-free structure. Specifically, the bosses 54, 54b are a stamping-free wire structure.

[0065] Preferably, pressure is applied to the wire 200 to cause a portion of the material in the wire 200 to flow, thereby forming the wire terminal 101. Furthermore, in this embodiment, the wire 200 is punched to cause a portion of the material in the wire 200 to flow, that is, the corresponding shape of the portion of the material on the wire 200 is deformed by external force.

[0066] Furthermore, pressure is applied to a predetermined position of the wire 200 to partially deform the wire 200 to form the retaining tail 50 as described in the first embodiment.

[0067] Furthermore, the formed wire terminal 101 is separated from the wire 200. That is, when one wire terminal 101 is formed on the wire 200, the wire terminal 101 is separated from the remaining material on the wire 200. The remaining material on the wire 200 can then be further processed to form a corresponding wire terminal 101. This operation can be repeated to produce a corresponding number of wire terminals 101.

[0068] As a variation, as needed, multiple wire terminals 101 can be arranged end-to-end along the extension direction of the wire 200. That is, the retaining tails 50 of any adjacent wire terminals 101 are connected to the free plug-in end 10. Furthermore, the multiple wire terminals 101 connected end-to-end can be cut into separate components.

[0069] It is understandable that the above manufacturing steps are not determined in a unique order. For the convenience of explanation, the above steps are only exemplary to illustrate the manufacturing process, and the corresponding manufacturing steps can be selected in a corresponding order according to the corresponding application conditions.

[0070] Example 3:

[0071] See also Figure 10 The present invention further provides a terminal assembly 103. The terminal assembly 103 includes at least two wire terminals 101 as described in the first embodiment. Any two adjacent wire terminals 103 are connected. The terminal assembly 103 is an integral part.

[0072] The number of wire terminals 101 included in each terminal assembly 103 is selected as needed. The direction in which the wire terminals 101 are arranged is selected as needed. Some or all of the wire terminals 101 are arranged sequentially in the same direction. That is, the plug-in free end 10 of at least one wire terminal 101 is connected to the retaining tail 50 of an adjacent wire terminal 101. Of course, as needed, the plug-in free end 10 of at least one wire terminal 101 is connected to the plug-in free end 10 of an adjacent wire terminal 101. As a variation, the retaining tail 50 of at least one wire terminal 101 is connected to the retaining tail 50 of an adjacent wire terminal 101.

[0073] In order to facilitate processing, the terminal assembly 103 also includes a connecting arm 60. The two ends of the connecting arm 60 are respectively connected to the two adjacent wire terminals 101. The specific shape and structure of the connecting arm 60 can be used as long as it can connect the two adjacent wire terminals 101. The connecting arm 60 can facilitate the overall transportation of multiple wire terminals 101 through connection, thereby saving manufacturing costs and facilitating subsequent processing to form a single wire terminal 101 as an independent component. In order to facilitate batch manufacturing and save materials, the connecting arm is a processing-free wire structure. More specifically, the connecting arm 60 is a stamping-free wire structure.

[0074] Depending on manufacturing requirements, one end of the connecting arm 60 can be connected to the free plug-in end 10 or the retaining tail 50 of one wire terminal 101. The other end of the connecting arm 60 can be connected to the free plug-in end 10 or the retaining tail 50 of another wire terminal 101. The longitudinal length of the connecting arm 60 can be sufficient to accommodate two wire terminals 101. Of course, depending on the selected cutting location, the connecting arm 60 can be separately provided on the retaining tail 50, forming a part of the structure of the wire terminal 101.

[0075] To minimize material consumption and facilitate mass production, the terminal assembly 103 is a single piece. More specifically, it is a stamped, one-piece component. It will be appreciated that when a separate component of the wire terminal 101 is required for a specific application, the separate component can be obtained by breaking the connecting arm 60. In other words, the connecting arm 60 is configured to be separable into two parts.

[0076] It should be noted that, in order to facilitate manufacturing and maintain the corresponding size of the wire terminals 101 produced in batches, the "wires" mentioned in the present invention are structures with uniform radial and lateral dimensions. Specifically, in this embodiment, the cross-section of the wire is rectangular. That is, the wire is in the shape of a rectangular cuboid. In addition, please continue to refer to Figure 1 The three arrows in the figure are perpendicular to each other and are used to indicate directions. Unless otherwise specified, the "up" and "down", "top" and "bottom" appearing in the present invention are all relative up and down in the "radial" direction; "left" and "right", "one side" and "the other side" are all relative left and right in the "transverse" direction; "longitudinal" and "axial" can be Figure 3 The "longitudinal direction" is limited in the upper and lower directions; the "horizontal direction" can be Figure 3 The width direction is limited to the left and right; the radial direction can be Figure 5 The above-defined directions of "thickness direction" and "height direction" are used to facilitate the description of the relative positions of various components based on the directions in the accompanying drawings.

Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
