[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0035] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0037] In the description of the embodiments of the present application, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present application generally indicates that the associated objects before and after are in an "or" relationship.

[0038] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. In addition, the directional terms mentioned in the embodiments of the present application, such as "inside", "outside", etc., are only references to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0039] In the prior art, the connector generally includes a metal terminal and a plastic bracket. The metal terminal is inserted into the plastic bracket. When the metal terminal is a cylindrical terminal, the outer contact surface of the cylindrical terminal is formed into an arch shape. Therefore, when the cylindrical terminal is assembled to the plastic bracket, it is necessary to ensure that the cylindrical terminal does not rotate, thereby ensuring the accurate transfer position of the cylindrical terminal and ensuring the normal use of the connector.

[0040] Generally, assemblers directly assemble the flat cylindrical terminals into the finished bracket. During the assembly process, the cylindrical terminals are prone to rotate to a certain extent, causing the position of the cylindrical terminals to rotate, affecting the normal use of the connector.

[0041] To solve the above technical problems, please refer to Figure 1 The present application provides a connector 100 . The connector 100 may include a bracket 120 and a terminal 110 .

[0042] For the convenience of explanation, a bracket coordinate system is established, with the axial direction of the terminal 110 as the X-axis, the YZ plane being perpendicular to the X-axis, and the X-axis, the Y-axis and the Z-axis being perpendicular to each other.

[0043] See also Figure 2 and Figure 3 The bracket 120 may include a first end 121 and a second end 122 opposite to each other and a mounting hole 123, in a direction from the first end 121 to the second end 122 (eg Figure 2 The mounting hole 123 passes through the bracket 120, and the mounting hole 123 may include a first hole section 1231 toward the first end 121 and a second hole section 1232 toward the second end 122. The radial dimension of the first hole section 1231 is greater than the radial dimension of the second hole section 1232, and the inner wall of the second hole section 1232 is provided with a protrusion 124. The terminal 110 can be inserted into the mounting hole 123.

[0044] See also Figure 4 and Figure 5 In a direction from the first end 121 to the second end 122 , the terminal 110 may include a first functional segment 111 and a second functional segment 112 in sequence.

[0045] The radial dimension of the first functional segment 111 is greater than the radial dimension of the second hole segment 1232, and is smaller than or equal to the radial dimension of the second hole segment 1232. It should be noted that the terminal 110 is inserted into the mounting hole 123 from the first end 121 of the bracket 120 toward the second end 122, and the first functional segment 111 cooperates with the first hole segment 1231. The first functional segment 111 can pass through the first hole segment 1231, but the first functional segment 111 cannot pass through the second hole segment 1232. The radial dimension of the second functional segment 112 is smaller than or equal to the radial dimension of the second hole segment 1232, that is, the second functional segment 112 cooperates with the second hole segment 1232, and the second functional segment 112 passes through the second hole segment 1232.

[0046] Please continue reading Figure 4 and Figure 5 , an annular groove 113 is provided on the circumferential side wall of the second functional segment 112, the annular groove 113 extends along the circumference of the second functional segment 112, and the protrusion 124 is suitable for being inserted into the annular groove 113 and having an interference fit with the annular groove 113. In the direction from the first end 121 to the second end 122, the distance between the protrusion 124 and the first end 121 is smaller than the distance between the annular groove 113 and the surface of the first functional segment 111 away from the second functional segment 112. Specifically, the first functional segment 111 includes a to-be-processed segment 1111 away from the second functional segment 112. When the protrusion 124 is inserted into the annular groove 113, the to-be-processed segment 1111 is located outside the mounting hole 123.

[0047] Please note that, please refer to Figures 6 to 10 When the protrusion 124 is inserted into the annular groove 113, the terminal 110 is in a position to be processed (for example Figure 1 ), at this time, the bracket 120 acts as a processing fixture. Since the protrusion 124 and the annular groove 113 are in interference fit, when the protrusion 124 is inserted into the annular groove 113, the axial movement is limited, and the terminal 110 cannot rotate. Then, the section to be processed 1111 is ground to form an arched surface. At this time, the terminal 110 after grinding is the finished terminal 110a, and then the finished terminal 110a is pushed into the mounting hole 123. In this way, the axial stroke during the assembly process of the finished terminal 110a and the bracket 120 can be reduced, thereby reducing the possibility of the finished terminal 110a rotating, thereby improving the yield rate of the finished connector 100a.

[0048] It should be noted that when the first functional section 111 is matched with the first hole section 1231 and the second functional section 112 is matched with the second hole section 1232, the finished terminal 110a is in the matched position with the bracket 120 (see Fig.10 ).

[0049] In the prior art, the outer peripheral surface of the finished terminal 110a needs to be gold-plated to achieve the stability of the electrical connection. Since the connector 100 in the present application is to grind the terminal 110 after the terminal 110 is matched with the bracket 120, and then move the ground finished terminal 110a to the matching position, and then gold-plated the two ends of the finished terminal 110a to achieve the stability of the electrical connection. Therefore, compared with the finished connector in the prior art, the finished connector 100a provided by the present application has a smaller gold-plated area and saves raw materials.

[0050] In some embodiments of the present application, there are multiple protrusions 124, and the multiple protrusions 124 are spaced apart in the circumferential direction of the second hole segment 1232, which can increase the force points and contact area between the protrusion 124 and the annular groove 113, making the fit between the protrusion 124 and the annular groove 113 more stable.

[0051] In some embodiments of the present application, the plurality of protrusions 124 may include a first protrusion 1241 and a first protrusion 1242, and the first protrusion 1241 and the first protrusion 1242 are arranged relative to each other. In this way, by arranging the protrusions 124 at symmetrical positions, the terminal 110 can be prevented from tilting due to uneven circumferential force, thereby further ensuring the yield of the finished connector 100a.

[0052] In a specific implementation process, there may be multiple first protrusions 1241 and multiple first protrusions 1242 , and the first protrusions 1241 correspond to and are opposite to the first protrusions 1242 one by one.

[0053] For example, the number of first protrusions 1241 is two, the number of first protrusions 1242 is two, and four protrusions 124 are evenly spaced and arranged on the inner wall of the second hole section 1232. Thus, the terminal 110 is prevented from tilting due to uneven circumferential force on the terminal 110, thereby ensuring the yield of the finished connector 100a.

[0054] In some embodiments of the present application, the protrusion 124 is formed in a ring shape, and the protrusion 124 extends along the circumferential direction of the second hole segment 1232. In this way, by providing the annular protrusion 124, the contact area between the protrusion 124 and the annular groove 113 can be maximized, thereby ensuring the stability of the terminal 110 in the position to be processed.

[0055] In some embodiments of the present application, the fitting tolerance between the protrusion 124 and the annular groove 113 is a first fitting tolerance, and the first fitting tolerance is greater than or equal to 0.03 mm and less than or equal to 0.05 mm.

[0056] In a specific implementation process, the first matching tolerance can be set to 0.03mm, 0.035mm, 0.04mm, 0.045mm, 0.05mm, etc. In this way, by limiting the size of the first matching tolerance, on the one hand, the stability of the matching between the protrusion 124 and the annular groove 113 can be ensured, and the stability of the terminal 110 in the position to be processed can be ensured; on the other hand, the height difference between the protrusion 124 and the annular groove 113 can be avoided to be too large, which may cause damage to the bracket 120 or the terminal.

[0057] In some embodiments of the present application, when the protrusion 124 is inserted into the annular groove 113, the distance between the surface of the section to be processed 1111 facing away from the second functional section 112 and the surface where the first end 121 is located is the processing distance, and the processing distance is greater than or equal to 0.6 mm and less than or equal to 1 mm.

[0058] In the specific implementation process, the processing distance can be set to 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, etc.

[0059] In this way, by limiting the processing distance, on the one hand, the travel of the finished terminal 110a after cutting to the mating position can be shortened, thereby reducing the rotation of the finished terminal 110a. On the other hand, it can avoid damaging the first end 121 of the bracket 120 when cutting the terminal 110.

[0060] In some embodiments of this application, please refer to Figure 4 and Figure 5 The second functional segment 112 may include a first guide segment 1121, which is located at one end of the second functional segment 112 away from the first functional segment 111, and the radial dimension of the first guide segment 1121 gradually decreases in the direction from the first functional segment 111 toward the second functional segment 112.

[0061] It should be noted that, when the terminal 110 is inserted into the mounting hole 123 , the first guide section 1121 first enters the mounting hole 123 . By providing the first guide section 1121 , the difficulty of assembly can be reduced.

[0062] Specifically, the first guide segment 1121 is formed by chamfering the edge of the end surface of the second functional segment 112 .

[0063] In some embodiments of this application, please continue to refer to Figure 4 and Figure 5The first functional section 111 may include a second guide section 1112, which is located at one end of the first functional section 111 close to the second functional section 112, and the radial dimension of the second guide section 1112 gradually decreases in the direction from the first functional section 111 to the second functional section 112. In this way, by providing the second guide section 1112, the difficulty of assembly can be reduced on the one hand, and on the other hand, when the finished terminal 110a after grinding is located at the mating position, the second guide section 1112 can be formed to avoid processing to avoid squeezing between the second hole section 1232 and the first functional section 111.

[0064] Specifically, the second guide segment 1112 is formed by chamfering the edge of the end surface of the first functional segment 111 .

[0065] In some embodiments of this application, please refer to Figure 2 The protrusion 124 may include a third guide segment 1243 near the first end 121, and in the direction from the first end 121 to the second end 122, the third guide segment 1243 extends in a direction away from the bottom wall of the protrusion 124. Therefore, the third guide segment 1243 is provided to facilitate the terminal 110 to avoid a hard collision between the terminal and the protrusion 124 during the process of moving from the first end 121 to the position to be processed.

[0066] In the specific implementation process, the outer edge of the cross-section of the protrusion 124 is formed as a minor arc, that is, an arc less than 180 degrees. Therefore, by setting the outer edge of the cross-section of the protrusion 124 as a minor arc, it is convenient to move the terminal from the first end 121 to the processing position, and at the same time, it is convenient to move the finished terminal 110a from the processing position to the mating position.

[0067] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0068] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
