Description

Technical Field

[0001] The invention relates to the technical field of connectors, in particular to a connector contact piece with a tapered gear sleeve, and a manufacturing method and a manufacturing tool for the connector contact piece. Background Art

[0002] Traditional connector contacts mainly include tooth sleeves and connecting posts, and the connecting posts are used to achieve contact connection between the connector contacts and other components. Figure 1 As shown, the tooth sleeve 100 is configured as an elastic part with an axial opening 101. The tooth sleeve is transferred to the transfer groove of the connecting column 200 through radial elastic deformation. The tooth sleeve 100 can be elastically supported on the inner wall of the connector product to prevent the connecting column 200 from axial movement, thereby realizing the limited fixation of the tooth sleeve 100 and the connecting column 200.

[0003] Traditionally, during the assembly process, reference Figure 2 As shown, the sleeve body of the gear sleeve needs to be radially expanded and deformed with the help of an expansion sleeve 300, and then axially moved to be installed in the transfer groove of the connecting column. This type of disadvantages: First, when the gear sleeve is opened and moved into the matching groove, the gear sleeve contacts the outer wall of the connecting column of the contact piece, which is easy to scratch the connecting column and affect the performance of the contact piece; second, the gear sleeve is easy to be over-opened and yield deformation occurs, resulting in a gap between the matching groove and the connecting column after assembly, affecting the axial movement of the connecting column in the mounting plate, and the contact piece is easy to withdraw or have poor contact. In addition, the gear sleeve of this type of contact piece is usually processed by stamping. The gear sleeve and connecting column produced by this processing method not only have obvious structural disadvantages, but also have a long manufacturing cycle and insufficient support force of the gear sleeve on the contact piece, resulting in high development costs of the gear sleeve and unstable mechanical properties. Summary of the invention

[0004] The purpose of the present invention is to provide a connector contact with a conical tooth sleeve, a method for manufacturing the connector contact, and a manufacturing tool for the connector contact. The connector contact has a connecting column that is easily scratched due to the limitations of the tooth sleeve structure and the assembly method. The connector contact has a gap with the assembly groove of the connecting column after yield deformation, which causes the contact to be easily withdrawn or have poor contact.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A connector contact with a tapered gear sleeve, comprising: a main body structure, a tapered gear sleeve and a tail attachment;

[0007] The outer wall of the main structure is provided with a first radially inwardly concave groove;

[0008] The front part of the conical gear sleeve is provided with a support ring whose inner wall matches the outer wall of the main structure and whose side wall is closed; the tail part of the conical gear sleeve is provided with a plurality of spring pieces arranged in a circumferential array and spread outward; the inner wall of the support ring is provided with a first protrusion which is radially inwardly convex and can be interference-fitted with the first groove;

[0009] A first limiting boss protruding radially outward is provided at one side of the front end of the first groove; the first limiting boss is used to abut against the support ring axially;

[0010] The tail attachment is detachably and fixedly connected to the tail end of the main structure.

[0011] The connector contact piece with a conical gear sleeve described in the present invention is configured such that the upper portion of the conical gear sleeve is configured as a support ring with closed side walls. The support ring is a supporting ring with closed side walls. The inner wall of the support ring matches the outer wall of the main structure. During the process of the conical gear sleeve being fitted onto the main structure, the first protrusion can just radially support the conical gear sleeve and produce elastic deformation in the radial direction, so that the conical gear sleeve can be axially slidably fitted onto the main structure without the need for stamping assembly. The first limiting boss is axially abutted against the support ring to prevent the conical gear sleeve from moving axially toward the front end, and a limiting protrusion is provided on the front end side of the first groove to make the first protrusion and the first groove interference connected to prevent the conical gear sleeve from moving toward the tail shaft. By moving the conical tooth sleeve in the direction of rotation, the conical tooth sleeve can be fixed to the outer wall of the main structure; after the main structure and the conical tooth sleeve are synchronously installed in the connector product, the spring piece opened outward can axially abut against the inner wall of the connector product shell, thereby realizing the fixation of the connector contact; since the conical tooth sleeve can be installed from the tail without the need for stamping assembly, the front end of the main structure of the contact piece will not be scratched, the appearance and contact connection of the contact piece product will not be affected, stamping assembly is not required, and yield deformation will not occur. The conical tooth sleeve is more accurately positioned and fixed to the outer wall of the main structure and is not easy to loosen, thereby avoiding the situation where the connector contact piece is withdrawn or has poor contact due to loosening of the main structure, thereby improving the product quality of the connector contact piece.

[0012] Preferably, in the connector contact with a conical gear sleeve described in the present invention, the first protrusion is an arc-surface protrusion; the axial cross-section of the first groove is square; and the arc-surface chord length of the first protrusion matches the width of the first groove.

[0013] As a preferred embodiment of the present invention, by setting the first protrusion as an arc-surface protrusion, in the process of the conical gear sleeve being inserted into the main structure from the tail of the main structure, the friction between the first protrusion and the outer wall of the main structure is reduced, the influence of the assembly of the conical gear sleeve on the appearance of the main structure is reduced, and the production quality of the connector contact is further improved; and, by setting the arc-surface chord length of the first protrusion and the width of the first groove to match, the first protrusion is just completely embedded in the first groove, the inner wall of the support ring and the outer wall of the main structure are tightly attached, the gap between the conical gear sleeve and the main structure is reduced, the possibility of the main structure loosening and needle withdrawal is reduced, and the stability of the connector contact is further improved.

[0014] Preferably, in the connector contact piece with a conical gear sleeve described in the present invention, the first protrusion is hemispherical; the support ring is located on the outer wall of the first protrusion and is provided with a concave hemispherical groove; the thickness between the bottom surface of the hemispherical groove and the inner wall of the first protrusion is equal to the thickness of the side wall of the support ring.

[0015] As a preferred embodiment of the present invention, by setting the first protrusion to a hemispherical shape, the friction between the conical gear sleeve and the main structure during the installation process can be further reduced, thereby further improving product quality; by providing a hemispherical groove, the position of the first protrusion can be conveniently observed from the outside during the installation process, which is beneficial to accurate alignment during the installation of the conical gear sleeve, further improving the accuracy of the assembly process, reducing assembly mechanical errors, and further improving the structural stability of the connector contact; and, the thickness of the bottom surface of the hemispherical groove and the inner wall diameter of the first protrusion are equal to the side wall thickness of the support ring, which can save materials, facilitate the processing design of the conical gear sleeve, reduce costs and improve the durability of the connector contact.

[0016] Preferably, in the connector contact with a conical gear sleeve described in the present invention, the tail of the main structure is provided with an empty tube section with a hollow interior, and the empty tube section is provided for the insertion of the tail accessory; the empty tube section is provided with a second protrusion, and the tail accessory is provided with a second groove that can be connected to the second protrusion by interference fit; the tail accessory is provided with a second limiting boss.

[0017] As a preferred embodiment of the present invention, by providing the second protrusion and the second groove, the tail accessory inserted into the empty pipe section can be connected to the main structure by interference fit; by providing the second limiting boss, the tail of the main structure can be limited to prevent the main structure from being damaged due to excessive axial movement, thereby enhancing the firmness of the connection of the tail accessory and the accuracy of positioning, and facilitating the detachable connection and assembly of the tail accessory.

[0018] Preferably, in the connector contact with a tapered gear sleeve described in the present invention, the tapered gear sleeve is a stainless steel component.

[0019] As a preferred solution of the present invention, compared with the traditional nickel-plated metal tooth sleeve, by setting the conical tooth sleeve as a stainless steel component, it does not need electroplating and can be directly processed and formed, which saves processing costs and improves production efficiency.

[0020] A method for manufacturing a connector contact comprises the following steps:

[0021] S1, manufacturing the conical gear sleeve by cutting, expanding and stamping processes, so that the conical gear sleeve is integrally formed;

[0022] S2. The integrally formed conical gear sleeve is subjected to a pre-collection process so that the spring pieces are pre-collected into a circular circumferential array.

[0023] The manufacturing method of the connector contact piece described in the present invention, through the above steps S1 to S2, the spring pieces of the conical gear sleeve manufactured can meet the corresponding requirements of the connector shell product, thereby enhancing the adaptability of the conical gear sleeve support in the shell. During the process of installing the conical gear sleeve and the main structure into the connector shell, the irregular elastic deformation of the spring pieces caused by the inconsistent opening angles of multiple spring pieces is reduced, thereby reducing the deformation effect of the spring piece deformation on the support ring, so that the conical gear sleeve is more accurately positioned and fixed to the outer wall of the main structure, and is not easy to loosen, thereby avoiding the situation where the connector contact piece is withdrawn or has poor contact due to loosening of the main structure, thereby improving the production quality of the connector contact piece.

[0024] A manufacturing tool for a connector contact, comprising: a cylindrical sleeve and a pushing cylinder; the inner diameter of the cylindrical sleeve is adapted to the standard opening angle of the free ends of a plurality of spring sheets, so that the conical gear sleeve can pass axially through the cylindrical sleeve; one end of the pushing cylinder is provided with a plurality of axially extending circumferentially arrayed pushing columns; the width of the pushing column is adapted to the spacing between two adjacent connecting ends of the spring sheets, so that the pushing column can be axially pushed on the support ring from one side of the spring sheet.

[0025] The manufacturing tooling of the connector contact piece described in the present invention, by setting a cylindrical sleeve and a pushing cylinder, can axially push the conical sleeve through the cylindrical sleeve from one side of the spring piece through the pushing cylinder after the conical sleeve is stamped and formed, and then pre-collect the opening angle of the spring piece according to the standard opening angle, thereby enhancing the adaptability of the conical sleeve support in the shell. During the process of installing the conical sleeve and the main structure into the connector shell, the irregular elastic deformation of the spring piece caused by the inconsistent opening angles of multiple spring pieces is reduced, thereby reducing the deformation effect of the spring piece deformation on the support ring, so that the conical sleeve is more accurately positioned and fixed to the outer wall of the main structure, and is not easy to loosen, thereby avoiding the situation where the connector contact piece is withdrawn or has poor contact due to loosening of the main structure, thereby improving the production quality of the connector contact piece.

[0026] Preferably, in the manufacturing tooling for the connector contact piece of the present invention, the push column is a square column; and both sides of the narrow surface of the push column are arranged radially.

[0027] As a preferred solution of the present invention, by setting the pushing column as a square column and arranging the two sides of the narrow surface radially, the effective area of ​​the pushing cylinder on the conical gear sleeve can be enhanced, so that the force at the gaps between the springs in the process of the conical gear sleeve being pushed through the cylindrical sleeve is more balanced, and the same cross-section of the conical gear sleeve can move axially synchronously, avoiding the pre-opening angle deviation of the springs due to uneven force, and further improving the manufacturing quality of the conical gear sleeve.

[0028] Preferably, in the manufacturing tooling for the connector contact piece of the present invention, the number of the push pins is half the number of the spring pieces.

[0029] As a preferred solution of the present invention, by setting the number of the pushing columns to be half the number of the spring pieces, it is possible to save materials while maintaining the stability of the pushing and pre-collecting of the conical gear sleeve by the pushing cylinder, further improving the production efficiency of the connector contact.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. The connector contact with a conical tooth sleeve can be fitted with the conical tooth sleeve from the rear end, and does not require stamping and assembly, so the front end of the main structure of the contact will not be scratched, the appearance and contact connection of the contact product will not be affected, and stamping and assembly are not required, and yield deformation will not occur. The conical tooth sleeve is more accurately positioned and fixed to the outer wall of the main structure and is not easy to loosen, thereby avoiding the situation where the connector contact is withdrawn or has poor contact due to looseness of the main structure, thereby improving the production quality of the connector contact.

[0032] 2. The manufacturing method and manufacturing tooling of the connector contact can enhance the adaptability of the conical gear sleeve support in the shell. When the conical gear sleeve and the main structure are installed into the connector shell, the irregular elastic deformation of the spring pieces caused by the inconsistent opening angles of multiple spring pieces is reduced, thereby reducing the deformation effect of the spring piece deformation on the support ring, so that the conical gear sleeve can be more accurately positioned and fixed to the outer wall of the main structure, and is not easy to loosen, thereby avoiding the situation where the connector contact piece is withdrawn or has poor contact due to loosening of the main structure, thereby improving the production quality of the connector contact piece.

[0046] It should be noted that the main structure 1 described in the present invention is understood as a part of a connector contact with a conical gear sleeve for plug connection, such as a connector pin. For details, please refer to Figure 3 As shown, the main structure 1 of the present invention is cylindrical; the front part is understood as Figure 3 The upper part of the main structure 1 shown, the part close to the front end for plug-in connection, the tail end is understood to be the end opposite to the front, and the tail is understood to be the part close to the tail end. The tail end of the tail accessory 3 in the present invention is used for the wiring connection of the connector, and the wiring method of the connector contact is four-point crimping or hexagonal crimping.

[0047] In the present invention, the first protrusion 211 and the first groove 11 can be connected by interference fit. Figure 6 As shown, the first protrusion 211 is a curved protrusion; the axial cross section of the first groove 11 is a square; the curved chord length of the first protrusion 211 matches the width of the first groove 11; more specifically, as Figure 6 As shown, the first protrusion 211 is hemispherical; the outer wall of the support ring 21 located on the first protrusion 211 is provided with a concave hemispherical groove 212; the thickness between the bottom surface of the hemispherical groove 212 and the inner wall of the first protrusion 211 is equal to the thickness of the side wall of the support ring 21.

[0048] Specifically, Figure 5 and Figure 7 As shown, the tail of the main structure 1 is provided with an empty pipe section 13 with a hollow interior, and the empty pipe section 13 is provided for the insertion of the tail accessory 3; the empty pipe section 13 is provided with a second protrusion 131, and the tail accessory 3 is provided with a second groove 31 that can be connected with the second protrusion 131 by interference fit; the tail accessory 3 is provided with a second limiting boss 32.

Specifically, multiple second protrusions 131 in a circumferential array can be formed by spot riveting around the main structure 1, and then the tail accessory 3 can be assembled and fixed to the tail of the main structure 1 by matching with the second groove 31.

[0049] It should be noted that the conical gear sleeve 2 of the present invention does not require electroplating compared to the traditional gear sleeve. The main structure 1, the conical gear sleeve 2 and the tail attachment 3 of the present invention are all made of metal. Specifically, the conical gear sleeve 2 is a stainless steel component. The use of stainless steel pipe profiles greatly improves material utilization and reduces costs. The profile structure is simple, which effectively reduces the processing and assembly time of parts.

[0050] It should be noted that the first limiting boss 12 of the present invention is arranged on the side of the first groove 11 close to the front end. Compared with the traditional gear sleeve assembly method, the conical gear sleeve 2 of the present invention cannot be assembled from the front of the main structure 1. The conical gear sleeve 2 is assembled from the tail to the front of the main structure 1, so that the conical gear sleeve 2 can be assembled and positioned and fixed to the main structure 1.

[0051] Embodiment 2:

[0052] This embodiment provides a method for manufacturing a connector contact piece, and manufacturing the connector contact piece with a tapered gear sleeve as described in Embodiment 1 includes the following steps:

[0053] S1, manufacturing the tapered gear sleeve 2 by cutting, expanding and stamping processes, so that the tapered gear sleeve 2 is integrally formed;

[0054] S2, subjecting the integrally formed conical gear sleeve 2 to a pre-collection process, so that the spring pieces 22 are pre-collected into a circular circumferential array.

[0055] It should be noted that the manufacturing method of the connector contact piece described in the present invention is not limited to steps S1 and S2. For example, for connector contacts with different sizes and mechanical performance requirements, the stainless steel pipe is cut into conical gear sleeves 2 parts of different lengths along the forming direction perpendicular to the profile; the main structure 1 can be made by the conventional one-piece molding process.

[0056] The pre-collection process described in the present invention is understood to be a step performed before the tapered gear sleeve 2 is assembled on the main structure 1. Since the spring pieces 22 may have inconsistent opening angles during the cutting or stamping process, the free ends of the plurality of spring pieces 22 are not arrayed in a circle, which easily affects the balance of the elastic force. Through step S2, the spring pieces 22 can be pre-collected into the tapered gear sleeve 2 required by the production standard, thereby improving the qualified rate of the product. Specifically, the pre-collection process can be performed as follows: Figure 8 The conical gear sleeve 2 is pre-made by the production tool.

[0057] Embodiment 3:

[0058] refer to Figure 8As shown, the present embodiment provides a manufacturing tool for a connector contact, which is used to manufacture a connector contact with a conical gear sleeve as described in Example 1, including: a cylindrical sleeve 4 and a pushing cylinder 5; the inner diameter of the cylindrical sleeve 4 is adapted to the standard opening angle of the free ends of a plurality of spring sheets 22, so that the conical gear sleeve 2 can pass axially through the cylindrical sleeve 4; one end of the pushing cylinder 5 is provided with a plurality of circumferentially arrayed push columns 51 extending axially; the width of the push column 51 is adapted to the spacing between the connecting ends of two adjacent spring sheets 22, so that the support ring 21 can be axially pushed from one side of the spring sheet 22.

[0059] It should be noted that the free end of the spring piece 22 described in the present invention is understood as the open end, and the standard opening angle is understood to adapt to different inner diameters of the connector housing. It is necessary to set spring pieces 22 with different opening angles to achieve elastic support of the spring piece 22. The inner diameter of the cylindrical sleeve 4 described in the present invention needs to be designed according to the standard opening angle to adapt and match the inner diameter and standard requirements.

[0060] refer to Figure 8 As shown, the distance between the push column 51 and the spring sheet 22 is adapted, which means that the width of the push column 51 is less than or equal to the distance between two adjacent spring sheets 22, so that the push column 51 can be located in the gap between the connecting ends of the two spring sheets 22 during pushing; specifically, the push column 51 of the present invention is a square column; the two sides of the narrow surface of the push column 51 are arranged radially.

[0061] The number of the push pins 51 described in this embodiment may be exactly the number of gaps between the connecting ends of two adjacent spring sheets 22, or it may be preferred that the number of the push pins 51 is half the number of the spring sheets 22. Figure 8 As shown, the number of the spring pieces 22 is eight, and the number of the pushing posts 51 is set to four, and the pushing posts 51 extend in the axial direction and can push the supporting ring 21 perpendicularly to the supporting ring 21 .
