[0002] In the current field of manufacturing electronic components and electrical parts, the touch parts of connector jacks and sockets, as key components, directly determine the reliability and stability of the entire system. Especially in high - requirement application scenarios such as aerospace and aviation, there are extremely strict standards for the reliability, soft pull force, touch resistance, seismic resistance, and shock resistance of connector jacks and sockets. These requirements have prompted manufacturers to continuously explore and innovate to develop more ideal touch part materials and manufacturing processes.

[0003] Refer to Figure 1 and Figure 2 , in order to meet these requirements, a metal terminal 1 with a cylindrical structure has emerged. The metal terminal 1 not only has a plurality of inclined grid slots 103, but also is specially designed with a partition slot, and the partition slot includes a first partition slot 104 and a second partition slot 105 that communicate with each other. During the process of winding the planar structure into a cylindrical structure, the edges of the partition slot are perfectly spliced to form a complete and solid cylindrical structure. At the same time, a plurality of inclined grid slots 103 are arranged circumferentially, and the length direction of each grid slot 103 is not parallel to the axis of the metal terminal 1.

[0004] Most of the existing metal terminal 1 forming molds can only complete simple stamping or forming tasks. For complex structures that require simultaneous cylindrical forming and inclined grid slot 103 processing, there are problems such as large forming difficulty and difficult precision control.

[0048] The following will be further described in detail with reference to the attached Figure 1-19 drawings to further illustrate this application.

[0049] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this application belongs. The "first", "second" and similar terms used in this application do not denote any order, quantity or importance, but are only used to distinguish different components.

[0050] For the sake of convenience of understanding, in the horizontal direction of this embodiment, the length direction of the mold is defined as the first direction, and the width direction of the mold is defined as the second direction. Based on this, the metal terminal forming mold will be described.

[0051] This embodiment of the application discloses a metal terminal 1 forming mold. Refer to Figure 3 , this embodiment of the metal terminal 1 forming mold discloses a metal terminal 1 forming mold. Referring to the figure, the metal terminal 1 forming mold includes two main parts: a fixed mold 2 and a moving mold 3. Through the precise cooperation between these two parts, a series of forming processes of the metal terminal 1 from raw material to finished product are realized.

[0052] Refer to Figure 1 and Figure 3, between the fixed mold 2 and the movable mold 3, there are successively arranged a punching mechanism 4, a grid groove forming mechanism 5, a chamfering mechanism 13, a wire clamping groove forming mechanism 6, a partition groove forming mechanism 7, a bending mechanism 8, a cylindrical forming mechanism 9, an inner support mechanism 11 and a torsion mechanism 12. The punching mechanism 4 is used for punching the strip material, the grid groove forming mechanism 5 is used for forming grid grooves 103 on the strip material, the chamfering mechanism 13 is used for chamfering the metal terminals 1, the wire clamping groove 102 forming mechanism is used for forming wire clamping grooves 102 on the strip material, and the wire clamping grooves 102 extend along the first direction. The partition groove forming mechanism 7 is used for forming a plurality of partition grooves with different shapes on the strip material, and the plurality of partition grooves are located between two adjacent metal terminals 1. The bending mechanism 8 is used for bending the edges of the metal terminals 1, the cylindrical forming mechanism 9 is used for forming the metal terminals 1 into a cylindrical shape, and the inner support mechanism 11 is used for supporting the inside of the metal terminals 1. The torsion structure is used for twisting the cylindrical metal terminals 1. These mechanisms operate on the metal strip material in a specific order and manner during the mold closing process of the metal terminal 1 forming mold, and finally obtain metal terminals 1 that meet the preset shape.

[0053] Refer to Figure 4 and Figure 5 , first of all, the punching mechanism 4 includes a first punch 41 and a corresponding first punch groove 42. The first punch 41 is fixed on the movable mold 3, and the first punch groove 42 is opened on the fixed mold 2. The first punch 41 is in plug-in fit with the first punch groove 42. The number of the punching mechanisms 4 can be one or more, and the shapes of each first punch 41 and the first punch groove 42 are different, which are used for punching holes with different shapes on the strip material. When the metal terminal 1 forming mold is closed, the first punch 41 moves downward under the drive of power and is accurately docked with the first punch groove 42, so as to punch the preset hole positions on the strip material. Multiple punching mechanisms 4 with different shapes can operate on the strip material simultaneously, greatly improving the punching efficiency and flexibility.

[0054] Refer to Figure 6 and Figure 8 , following closely is the grid groove forming mechanism 5. The grid groove forming mechanism 5 includes a plurality of second punches 51 and second punch grooves 52. The plurality of second punches 51 are fixed on the movable mold 3, and the second punch grooves 52 are opened on the fixed mold 2. The shapes and distribution positions of these punches and punch grooves are carefully designed to ensure that a plurality of grid grooves 103 are accurately formed on the strip material (in combination with Figure 5 ), the specific grid groove 103 is a strip-shaped groove, and both ends of the strip-shaped groove are provided with rounded corners. The formation of the grid groove 103 not only enhances the structural strength of the metal terminal 1, but also helps to improve its stability and reliability in actual use.

[0055] Refer to Figure 1 and Figure 3, Subsequently, the clip slot forming mechanism 6 includes a plurality of third punches and third slots. The plurality of third punches are fixed on the moving die 3, and the plurality of third slots are formed on the fixed die 2. They cooperate when the metal terminal 1 forming die is closed, and accurately form the clip slot 102 on the strip. The clip slot 102 further enhances the aesthetics of the metal terminal 1.

[0056] Refer to Figure 1 and Figure 4 , Next is the separation slot forming mechanism 7. The separation slot forming mechanism 7 includes a first slot forming component 71 and a second slot forming component 72. The first slot forming component 71 is used to form the first separation slot 104 on the strip, and the second slot forming component 72 is used to form the second separation slot 105 on the strip. Both the first separation slot 104 and the second separation slot 105 are located between two adjacent metal terminals 1.

[0057] Refer to Figure 9 and Figure 10 , The first slot forming component 71 includes a first pressing block 711 and a first groove 712. The first pressing block 711 is fixed on the moving die 3, and the first groove 712 is formed on the fixed die 2. The first pressing block 711 is inserted and matched with the first groove 712. The shapes of both the first pressing block 711 and the first groove 712 are adapted to the shape of the first separation slot 104. During the closing process of the metal terminal 1 forming die, the first pressing block 711 descends and cooperates with the first groove 712 to accurately press out the shape of the first separation slot 104 on the strip.

[0058] Refer to Figure 11 and Figure 12 , The second slot forming component 72 includes a second pressing block 721 and a second groove 722. The second groove 722 is arranged on the moving die 3, and the second groove 722 is formed on the fixed die 2 (in combination with Figure 4 ), the second pressing block 721 is inserted and matched with the second groove 722; the shapes of both the second pressing block 721 and the second groove 722 are adapted to the shape of the second separation slot 105. The formation of these two separation slots not only facilitates the separation of two adjacent metal terminals 1, but also provides a necessary structural basis for the subsequent cylinder forming.

[0059] Refer to Figure 1 and Figure 4 , After the separation slot is formed, the bending mechanism 8 starts to bend the edges of the metal terminal 1. The bending mechanism 8 includes an angle bending component 81 and a fillet bending component 82. The angle bending component 81 is used to bend the edges of the flat metal terminal 1, so as to process a bending part on the edges of the metal terminal 1. The bending part is not in the same plane as the metal terminal 1. The fillet bending component 82 is used to process the bending part from a planar shape into an arc shape. They cooperate with each other when the metal terminal 1 forming die is closed, and bend the edges of the metal terminal 1 into a preset angle.

[0060] Refer to Figure 13 and Figure 14 , the angle bending assembly 81 includes a first bending block 811 and a second bending block 812. The first bending block 811 is fixed to the stationary mold 2, and the second bending block 812 is fixed to the moving mold 3. When the metal terminal 1 forming mold is closed, it drives the second bending block 812 to move towards the direction close to the first bending block 811, so as to realize bending the edge of the metal terminal 1. Through the cooperation of the first bending block 811 and the second bending block 812, the angle bending assembly 81 can accurately bend the edge of the metal terminal 1 when the metal terminal 1 forming mold is closed, improving the forming accuracy and stability of the metal terminal 1 (combining Figure 1 and Figure 2 ).

[0061] Refer to Figure 15 and Figure 16 , the fillet bending assembly 82 includes a first forming block 821 and a second forming block 822. The first forming block 821 is fixed to the stationary mold 2, and an arc-shaped groove 823 is formed on the first forming block 821. The second forming block 822 is fixed to the moving mold 3, and an arc-shaped convex block 824 is fixedly arranged on the second forming block 822, and a fillet is arranged on the edge of the arc-shaped convex block 824; when the metal terminal 1 forming mold is closed, it drives the second forming block 822 to move towards the direction close to the second bending block 812, so as to realize processing the edge of the metal terminal 1 into an arc shape. Through the cooperation of the first forming block 821 and the second forming block 822, the fillet bending assembly 82 can process the bending part of the metal terminal 1 into an arc shape when the metal terminal 1 forming mold is closed, improving the appearance quality and feel of the metal terminal 1.

[0062] Refer to Figure 17 and Figure 18 , the last step is to complete the cylindrical forming of the metal terminal 1 by the cylindrical forming mechanism 9. The number of the cylindrical forming mechanisms 9 is multiple, and each cylindrical forming mechanism 9 includes a first pressing block 91 and a second pressing block 92. The first pressing block 91 is fixed to the stationary mold 2, and a semi-circular first forming groove 93 is formed at the top of the first pressing block 91. The second pressing block 92 is fixed to the moving mold 3, and a semi-circular second forming groove 94 is formed on the lower surface of the second pressing block 92. When the metal terminal 1 forming mold is closed, they are butt-jointed with each other and clamp the metal terminal 1 in the middle, and the metal terminal 1 undergoes plastic deformation under the action of pressure, and finally forms a cylindrical structure. The design of the cylindrical forming mechanism 9 fully considers the structural characteristics and actual use requirements of the metal terminal 1, ensuring that the formed metal terminal 1 has excellent structural strength and reliability.

[0063] Refer to Figure 3 and Figure 4, an inner support mechanism 11 is also provided on the fixed mold 2. When the cylindrical forming mechanism 9 processes the metal terminal 1 into a cylindrical shape, the inner support mechanism 11 is used to support the inner side wall of the metal terminal 1. The setting of the inner support mechanism 11 effectively supports the inner side wall of the metal terminal 1 during the cylindrical forming process, preventing deformation and collapse during the forming process, ensuring the integrity and firmness of the cylindrical structure, and improving the overall performance and reliability of the metal terminal 1.

[0064] Referring to Figure 19 , the inner support mechanism 11 includes an inner support rod 111 and a sliding drive member 112. The sliding drive member 112 is arranged on the fixed mold 2, and the sliding drive member 112 is used to drive the inner support rod 111 to move in a direction close to or away from the tape channel. Specifically, the sliding drive member 112 can be a cylinder, the cylinder is fixed on the fixed mold 2, and the piston rod of the cylinder is fixedly connected to the inner support rod 111. The design of the inner support mechanism 11 using the inner support rod 111 and the sliding drive member 112 realizes precise control and flexible adjustment of the inner side wall of the metal terminal 1. When the tape channel is feeding, the inner support rod 111 is moved to the outside of the tape channel through the drive member, thereby increasing the smoothness of the tape channel feeding; when the cylindrical forming mechanism 9 is forming the cylindrical metal terminal 1, the inner support rod 111 is driven by the sliding drive member 112 to move into the metal terminal 1, thereby preventing deformation and collapse during the forming process and ensuring the integrity and firmness of the cylindrical structure.

[0065] Continue to refer to Figure 19 , the inner support rod 111 is cylindrical, and the diameter of the outer side wall of the inner support rod 111 is the same as the diameter of the inner side wall of the metal terminal 1. The inner support rod 111 is designed to be cylindrical, and the diameter of its outer side wall is the same as the diameter of the inner side wall of the metal terminal 1, ensuring the optimization of the support effect, avoiding forming problems caused by insufficient or excessive support, and further improving the qualification rate and quality stability of the metal terminal 1.

[0066] Continue to refer to Figure 19 , a guide block 113 is fixedly arranged on the inner support rod 111, and a second guide groove 22 is formed on the fixed mold 2. The guide block 113 is in sliding fit with the second guide groove 22. The sliding fit between the guide block 113 fixedly arranged on the inner support rod 111 and the second guide groove 22 on the fixed mold 2 provides stable guidance and limit for the movement of the inner support rod 111, ensures the accuracy and reliability of the inner support action, simplifies the structure of the forming die, and is convenient for maintenance and operation.

[0067] Continue to refer to Figure 19, the twisting mechanism 12 includes a support 121, a telescopic twisting rod 122, a rotary driving member 123, and a telescopic driving member 124. The support 121 is fixed to the fixed mold 2. The telescopic twisting rod 122 passes through the support 121. The telescopic twisting rod 122 is rotatably connected to the support 121 and is slidably engaged with the support 121. The telescopic driving member 124 is used to drive the telescopic twisting rod 122 to slide in a direction close to or away from the strip channel. The rotary driving member 123 is used to drive the telescopic twisting rod 122 to rotate. Specifically, the telescopic driving member 124 can be a cylinder, which can be fixed to the support 121 or fixed to the fixed mold 2. The piston rod of the cylinder is fixedly connected to the end of the telescopic twisting rod 122 through a connecting block. Specifically, the rotary driving member 123 can be a motor, which can be arranged on the support 121 and is used to drive the telescopic twisting rod 122 to rotate. The design of the twisting mechanism 12, especially the rotational connection and sliding fit between the telescopic twisting rod 122 and the support 121, as well as the coordinated action of the telescopic driving member 124 and the rotary driving member 123, makes the twisting forming process of the cylindrical metal terminal 1 more stable and controllable, effectively solving the problem of the difficult processing of the inclined grid groove 103.

[0068] Continue to refer to Figure 19 , a guide post 125 is arranged on the telescopic twisting rod 122. The diameter of the guide post 125 is larger than that of the telescopic twisting rod 122. A first guide groove 21 is formed on the fixed mold 2. The first guide groove 21 extends in the horizontal direction. The guide post 125 is slidably engaged with the first guide groove 21 and is rotatably connected to the first guide groove 21. The sliding fit and rotational connection between the guide post 125 arranged on the telescopic twisting rod 122 and the first guide groove 21 on the fixed mold 2 provide stable guidance and support for the twisting process, ensuring the accuracy and consistency of the twisting, and further improving the precision and quality of the metal terminal 1.

[0069] Continue to refer to Figure 19 , the first guide groove 21 is an arc-shaped groove. The first guide groove 21 extends in the horizontal direction. The outer side wall of the guide post 125 abuts against the inner side wall of the first guide groove 21. The first guide groove 21 is designed as an arc-shaped groove and tightly abuts against the outer side wall of the guide post 125, which not only optimizes the mechanical distribution during the twisting process, but also reduces friction and wear, extends the service life of the forming mold, and reduces the maintenance cost.

[0070] The implementation principle of the above embodiments is as follows: During the manufacturing process, the strip first passes through the grid groove forming mechanism 5, which can accurately form the required grid grooves 103 on the strip; immediately afterwards, the partition groove forming mechanism 7 forms partition grooves on the strip, and these partition grooves are located between adjacent two metal terminals 1, playing a role in separation and positioning. Subsequently, the strip enters the bending mechanism 8, and the edge of the strip is bent through the bending action to prepare for the subsequent cylindrical forming; the cylindrical forming mechanism 9 processes the metal terminals 1 that have gone through the previous processes into a cylindrical shape; finally, the crucial torsion mechanism 12 comes into play, and by twisting the cylindrical metal terminals 1, the grid grooves 103 are made to be inclined, meeting the specific structural requirements of the metal terminals 1.

[0071] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
