Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an embedded terminal group for connectors. Background Art

[0002] At present, with the rapid development of electronic technology, there are more and more electronic products. Connectors have become an indispensable part of electronic equipment and play an important role in data transmission. There are two ways to transmit data between various smart products and electronic computers and mobile data terminals. One is wireless transmission technology, and the other is mainly bridged by data cables. Existing data cables usually use connector plugs and connector sockets to connect.

[0003] In the prior art, a USB connector generally includes a metal shell, a plastic body mounted on the metal shell, and a terminal group embedded in the plastic body. The terminal group is generally formed by stamping, where a plate is first prepared, and multiple terminals are stamped out of the plate by a stamping die. The extra parts at both ends of the multiple terminals are used to support the material strips of the multiple terminals. The material strips can be used to maintain the positions of the various terminals, so as to facilitate the subsequent injection molding of the plastic body.

[0004] The inventor discovered during actual production operations that for some connectors that require embedded terminals, the material strip is connected to the ends of multiple terminals; when injection molding with the plastic body, the material strip at the front end of the terminal needs to be punched and cut before it can be buried in the plastic of the plastic body; when the material strip of the terminal is cut, a punched-out section will be formed at the head end of the terminal, and the punched-out section lacks a surface treatment coating, which makes the terminal prone to oxidation corrosion, seriously affecting the service life of the terminal.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0047] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application 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 application.

[0048] In addition, 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, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0050] Before explaining the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first described.

[0051] Please also read Figure 1 , is a schematic diagram of the structure of the terminal group stamping in the prior art; this type of terminal group 1' has a material strip 2' at both ends. When the head end of each terminal of the terminal group needs to be buried in the plastic body, it is first necessary to punch it through a stamping die, and then inject plastic to complete the embedding of the head end of each terminal of the terminal group into the plastic. After each terminal is punched, if it is necessary to transfer the terminal to a surface treatment station for processing, it is easy to be displaced due to the movement of the terminal, and it is difficult to ensure whether the position of each terminal meets the design requirements. Usually, plastic is injected directly after each terminal is punched; and since a punching cut section will appear after each terminal is punched, even after being buried in the plastic body, there will still be a certain seam between the punching cut section of the plastic body and the front surface of each terminal. Since the punching cut section has no surface treatment, it is easy for the terminal to be corroded and oxidized after a period of use, which seriously affects the service life of the terminal group, thereby limiting the service life of the connector.

[0052] Therefore, the present application provides an embedded terminal group for a connector, which can effectively solve the technical problem in the prior art that the terminal group is easily corroded and oxidized due to the cut section caused by the punching of the material strip, thereby improving the service life of the terminal group, and further extending the service life of the connector provided with such a terminal group.

[0053] Please also read Figures 2 to 6 Now, the embedded terminal set for the connector provided in the embodiment of the present application is described. The embedded terminal set for the connector at least includes a first copper plate 10.

[0054] The first copper plate 10 is punched by a stamping die to stamp out a first supporting material strip 11, a first main material strip 12 and a first terminal group; the first terminal group has a plurality of first terminals 13 spaced from left to right, and the first main material strip 12 is integrally formed at the ends of the plurality of first terminals 13; the first supporting material strip 11 is respectively integrally formed with the two outermost first terminals 13 in the first terminal group.

[0055] Specifically, by setting up the first supporting material strip 11 and the first main material strip 12, the first supporting material strip 11 is only integrally formed with the two outermost first terminals 13 among the first terminals 13, and the first main material strip 12 is integrally formed at the ends of the multiple first terminals 13; with such a structure, the head ends of the multiple first terminals 13 do not need to be provided with material strips to integrally mold each first terminal 13, and when they are subsequently integrally molded with the plastic body, the head ends of the first terminals 13 do not need to be cut to complete the embedded setting of the first terminals; there will be no cutting surface at the head ends of the first terminals 13, thereby preventing the problem of oxidation corrosion of the first terminals after cutting, and further improving the service life of the terminals.

[0056] In the embodiment of the present application, the first terminal 13 includes a first plug-in portion 131, a first embedded portion 132 and a first connecting portion 133. The first embedded portion 132 is integrally formed at the end of the first plug-in portion 131, and the first connecting portion 133 is integrally formed at the end of the first embedded portion 132; the first main material strip 12 and the ends of the first connecting portions 133 of several first terminals 13 are integrally formed together, and the first supporting material strip 11 and the end side of the first plug-in portion 131 of the outermost first terminal 13 are integrally formed together.

[0057] Exemplarily, the first terminal group includes eight first terminals 13 spaced to the right, wherein one side of the first terminal is integrally formed with the first supporting material strip 11 , and the eighth first terminal 13 is integrally formed with the first supporting material strip 11 .

[0058] In some other embodiments of the present application, the first copper plate 10 is also stamped with a second terminal group, and the specific structure of the second terminal group is roughly the same as the specific structure of the first terminal group. The second terminal group includes a plurality of second terminals 14 spaced from left to right, the second terminal 14 includes a second plug-in portion 141, a second embedded portion 142 and a second connecting portion 143, the second embedded portion 142 is integrally formed at the end of the second plug-in portion 141, and the second connecting portion 143 is integrally formed at the end of the second embedded portion 142; the ends of the second connecting portions 143 of the plurality of second terminals 14 are integrally formed with a second main material strip 15, and the first supporting material strip 11 is integrally formed with the end side of the second plug-in portion 141 of the outermost second terminal 14.

[0059] Specifically, a first auxiliary material connecting strip 16 is integrally formed between the first plug-in portions 131 of each first terminal 13 and between the second plug-in portions 141 of each second terminal 14, and the first auxiliary material connecting strip 16 is used to equally space the first plug-in portions 131 of each first terminal 13 and the second plug-in portions 141 of each second terminal 14 and provide support.

[0060] Preferably, the first auxiliary material connecting strip 16 is connected to the middle rear position of the first plug-in portion 131 of each first terminal 13, and the first auxiliary material connecting strip 16 is connected to the middle rear position of the second plug-in portion 141 of each second terminal 14; thereby, after each first terminal 13 and second terminal 14 are punched and formed, the position accuracy meets the design requirements and is not prone to deviation, thereby ensuring that the subsequently formed plastic body can move forward reliably.

[0061] A plurality of second auxiliary material connecting strips 111 are arranged on the left and right sides of the first supporting material strip 11; the end side surfaces of the first plug-in portions 131 of the two outermost first terminals 13 in the first terminal group are integrally formed with the second auxiliary material connecting strip 111, and the end side surfaces of the second plug-in portions 141 of the two outermost second terminals 14 in the second terminal group are integrally formed with the second auxiliary material connecting strip 111.

[0063] Specifically, since the first tongue plate plastic body 17 and the first plastic support body 18 are directly injection molded on each first terminal 13, and the second tongue plate plastic body 19 and the second plastic support body 110 are injection molded on each second terminal 14, it is convenient to subsequently bend the first terminal 13 and the second terminal 14, and each terminal is not prone to displacement when being bent; at the same time, since the first terminal group and the second terminal group are integrally formed on the same first copper plate 10, the first supporting material strip 11 can be bent subsequently to achieve the upper and lower overlap of the first terminal group and complete the assembly operation.

[0064] Preferably, the first tongue plate plastic body 17 has a first avoidance window 171 penetrating the upper and lower surfaces thereof, and the first avoidance window 171 can expose the first auxiliary material connecting strips 16 of each first terminal 13 and each second terminal 14. Due to the provision of the first avoidance window 171, the first auxiliary material connecting strips 16 between each first terminal 13 and the first auxiliary material connecting strips 16 between each second terminal 14 can be exposed; and at this time, each first terminal 13 has been finalized due to the first tongue plate plastic body 17 and each second terminal 14 has been finalized due to the second tongue plate plastic body 19, and after punching out the first auxiliary material connecting strips 16, the plastic body is directly injection molded subsequently, and the first avoidance window 171 is completely buried, so that oxidation corrosion can be prevented from being caused to the punched-out section between the first terminal 13 and the first auxiliary material connecting strip 16 and the punched-out section between the second terminal 14 and the first auxiliary material connecting strip 16.

[0065] It also includes a second copper plate 20, which is stamped with a second support strip 21 and a second middle clip 22. The second support strip 21 and the first support strip 11 are stacked up and down, and the second middle clip 22 and the first plug-in portion 131 of the first terminal 13 are spaced apart up and down.

[0066] In more detail, the first plastic support 18 is provided with a plurality of first plugging posts 181, and the second plastic support 110 is provided with a plurality of first plugging holes 1101 for inserting the first plugging posts 181 one by one. The first main material strip 12 is provided with a first convex ring 121, and the second main material strip 15 is provided with a first rivet hole 151 for riveting the first convex ring.

[0067] The specific manufacturing steps are: first, the first terminal group and the second terminal group are integrally stamped on the first copper plate 10; the second support strip 21 and the second middle clip 22 are stamped on the second copper plate 20; then the second support strip 21 and the first support strip 11 are stacked up and down, and the second middle clip 22 and the first terminal 13 are set at a distance from each other; then the first terminal group is injection molded with the first tongue plate plastic body 17, the first terminal group and the second middle clip 22 are covered with the first tongue plate plastic body 17, and the first plastic support body 18 is injection molded; at the same time, the second terminal group is injection molded with the second tongue plate plastic body 19 and the second plastic support body 110; then the first support strip 11 is bent so that the second terminal group and the first terminal group are stacked up and down, and a plurality of first plug-in columns 181 are inserted one by one into the plurality of first plug-in holes 1101, and the first convex ring is riveted into the first rivet hole to complete the assembly of the first terminal group and the second terminal group, and the semi-finished product of the terminal group can be obtained by injection molding the plastic body.
