Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a middle clip structure for a Type-C connector. Background Technology

[0002] The Type-C connector is a hardware interface for the Universal Serial Bus (USB). It has an oval shape, a small size, and identical top and bottom ends, which avoids damage to the interface or device due to incorrect insertion and greatly improves ease of use.

[0003] Type-C connectors incorporate a center clip, which shields interference signals, preventing terminals from interfering with each other and achieving high-frequency transmission. The center clip also separates terminal blocks. However, current Type-C connector center clips have the following problems: During stamping, the center clip head is sometimes cut without considering clearance, resulting in insufficient machining precision or positional deviations during assembly. This can lead to insufficient insulation distance between the center clip and adjacent gold fingers. When current flows, it may flow in paths that shouldn't be conductive, posing a short-circuit risk. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a middle clip structure for a Type-C connector, wherein the front end of the middle clip is provided with a first clearance position to reduce the risk of short circuit.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A type-C connector with a middle clip structure includes a core and a middle clip. The middle clip is embedded inside the core. Several first gold fingers are arranged side by side above the middle clip, and several second gold fingers are arranged side by side below the middle clip. The front ends of the first and second gold fingers are all provided with bent portions. The front end of the middle clip is provided with a first clearance in the area of ​​the bent portion. Several positioning holes are also provided on the middle clip at intervals. The positioning holes are used for connecting the core above the middle clip and the core below the middle clip.

[0007] In some implementations, the positioning hole is rectangular, and the four corners of the positioning hole are rounded.

[0008] In some embodiments, the front end of the middle clip is provided with side protrusions on both sides of the first clearance position.

[0009] In some implementations, feed arms are provided on both sides of the middle clamp.

[0010] In some embodiments, terminals are fixedly connected to the rear ends of both the first gold finger and the second gold finger. The terminals are provided with a first Z-shaped bend, and one end of the first Z-shaped bend away from the first gold finger or the second gold finger extends out of the rear part of the glue core.

[0011] In some embodiments, a second clearance is provided in the area of ​​the rear part of the middle clip located at the first Z-shaped bend, and a second Z-shaped bend is provided on both sides of the rear part of the middle clip located at the second clearance.

[0012] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0013] (1) The front ends of the first gold finger and the second gold finger are embedded in the core through the bending part to fix the first gold finger and the second gold finger. The first clearance at the front end of the middle clip can avoid the bending part, so as to avoid the current being generated on the path that should not be connected due to insufficient insulation distance between the bending part of the first gold finger and the second gold finger and the middle clip or position deviation during the assembly process, i.e., short circuit. This improves the core quality of the Type-C connector and ensures stable transmission of signal and current when the Type-C connector is connected.

[0014] (2) Several positioning holes can provide sufficient space for the flow of rubber material during injection molding of the core, avoid material shortage, and improve the connection strength between the core and the middle clip after the core is formed. Attached Figure Description

However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of this application more complete and to fully convey the concept of the present application to those skilled in the art.

[0022] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] like Figures 1-4As shown in the embodiment of this application, a type-C connector middle clip structure includes a core 1 and a middle clip 2. The middle clip 2 is embedded inside the core 1. Several first gold fingers 3 are arranged side by side above the middle clip 2, and several second gold fingers 4 are arranged side by side below the middle clip 2. The front ends of the first gold fingers 3 and the second gold fingers 4 are all provided with bent portions 5. The front end of the middle clip 2 is provided with a first clearance 21 in the area of ​​the bent portion 5. The first clearance 21 is a notch formed by stamping. Several positioning holes 22 are also provided on the middle clip 2 at intervals. The positioning holes 22 are used for connecting the core 1 above the middle clip 2 and the core 1 below the middle clip 2.

[0024] In operation, the front ends of the first gold finger 3 and the second gold finger 4 are embedded in the core 1 through the bending portion 5, thereby fixing the first gold finger 3 and the second gold finger 4. The first clearance position 21 at the front end of the middle clip 2 can avoid the bending portion 5, preventing current from being generated on a path that should not be conductive due to insufficient insulation distance between the bending portion 5 of the first gold finger 3 and the second gold finger 4 and the middle clip 2 or positional deviation during assembly, thus improving the quality of the Type-C connector core and ensuring stable signal and current transmission when the Type-C connector is connected. Several positioning holes 22 can provide sufficient space for the flow of rubber material during injection molding of the core 1, avoiding material shortage, and improving the connection strength between the core 1 and the middle clip 2 after the core 1 is formed.

[0025] The positioning hole 22 is rectangular, and the four corners of the positioning hole 22 are rounded 221. During the processing stage, the positioning hole 22 is punched on the middle clamping piece 2. The rounded corner 221 can reduce the probability that the punch retraction will cause the middle clamping piece 2 to retract together.

[0026] The front end of the middle clip 2 is provided with side protrusions 23 on both sides of the first clearance position 21. The middle clip 2 is made of metal. When the Type-C connector is inserted with the male connector, the side protrusions 23 on both sides of the front end of the middle clip 2 contact the male connector, thereby reducing the wear of the male connector on the core 1 and extending the insertion and removal life of the core 1.

[0027] Material arms 24 are provided on both sides of the middle clamping piece 2; the material arms 24 facilitate the connection between the middle clamping piece 2 and the material strip and the punching.

[0028] Terminals 6 are fixedly connected to the rear ends of the first gold finger 3 and the second gold finger 4. The terminal 6 is provided with a first Z-shaped bend 61. The end of the first Z-shaped bend 61 away from the first gold finger 3 or the second gold finger 4 extends out of the rear of the core 1, thereby connecting with the external circuit board.

[0029] The rear part of the middle clip 2 is provided with a second clearance 25 in the area of ​​the first Z-shaped bend 61. The second clearance 25 is a notch formed by stamping. The rear part of the middle clip 2 is provided with second Z-shaped bends 26 on both sides of the second clearance 25. The second clearance 25 can avoid part of the first Z-shaped bend 61 to prevent interference.

[0030] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
