Abstract
Description
Technical Field
[0001] This utility model relates to electrical connection technology, and more particularly to providing a circular connector. Background Technology
[0002] Existing circular connectors are mostly RJ45 type and high-current pin connectors. There are no connectors with the same functionality as this structure, especially those with elastic clamping terminals inside the tongue plate. These connectors have multiple transmission functions and high precision, and are frequently used for mating. When mating the mating ends with the clamping terminals, they are first aligned through the mating holes on the front of the tongue plate. Because the mating ends of the mating connectors are long and thin, wear and tear during use can affect precision, leading to poor mating and product damage. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the main objective of this utility model is to provide a circular female connector and a circular male connector adapted to the circular female connector.
[0004] To achieve the above objectives, the technical solution applied in this utility model is as follows:
[0005] This utility model discloses a circular connector, including an insulator and terminal pieces. The insulator includes a front section, a rear section, and a partition between the front and rear sections. The front section has a hollowed-out cavity with a tongue plate inside. The root of the tongue plate is integrated with the partition. The tongue plate has a row of terminal slots that extend through the partition from the insertion end face. Each terminal slot includes an inlet with a flared opening that guides insertion and a movable slot connecting the inlet. The terminal pieces include insertion terminals and a rear plug. The number of insertion terminals corresponds to the number of terminal slots. Each insertion terminal includes a fixing part and two symmetrical spring arms at the front end of the fixing part, which are arranged in the terminal slots. The free ends of the two spring arms are inclined inward and form opposing contacts. The two contacts are arc-shaped, and the figure-eight shape formed by the arc ends is aligned to receive the flared opening.
[0006] Preferably, the terminal slots passing through the partition are partition holes, and a mounting platform is formed at the rear. The mounting platform has a mounting groove with a rear opening. The rear plug is a strip formed by embedding the fixing part in the mold. The strip is adapted to the mounting groove, and the rear end of the fixing part is connected to a foot.
[0007] Preferably, the fixing part is a side-standing U-shaped body formed by stamping sheet metal, one of the two elastic arms and the end foot are formed by extending back to back on the front and back of the same side of the U-shaped body, and the other elastic arm is symmetrically formed on the other side of the U-shaped body.
[0008] Compared with the prior art, this invention offers the following advantages: Because these connectors have high precision and correspondingly long and thin insertion segments, when used with this circular connector, wear and tear can cause insufficient precision, leading to damage to the insertion segment and resulting in poor connection. Therefore, the flared insertion design of this circular connector is particularly necessary to extend product lifespan. Attached Figure Description

Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."
[0016] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0017] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0020] In this embodiment, as Figures 1 to 4The circular connector 1 shown includes an insulator 10 and terminal pieces 20 assembled in the insulator 10. The insulator 10 is divided into a front section 11, a rear section 12, and a partition (not labeled) between the front and rear sections. The front section is a hollowed-out cavity 111, in which a tongue plate 13 is formed. The root of the tongue plate is integrated with the partition. The tongue plate has a row of terminal slots 131 that penetrate the partition from the insertion end face. The terminal slots are divided into an entrance portion 1311 and a movable slot 1312. The upper and lower walls of the entrance portion 1311 are recessed into the upper and lower walls of the movable slot 1312, respectively, so that a stepped surface (i.e., a "shielding surface") 1313 is formed between the two. The entrance portion opposite to the shielding surface forms a flared mouth 1314 for guiding insertion. A partition hole 14 is formed through the partition. The rear section 12 forms a mounting platform 121, which has a mounting slot 1211 with a rear opening. Terminal 20 includes plug terminals 21 and a rear plug 22 that securely holds several plug terminals side-by-side. The number of plug terminals corresponds to the number of holes 14 in the partition plate. The rear plug 22 is a strip formed by an embedded mold to fit the mounting groove 1211. The plug terminal 21 includes a fixing part 211, a spring arm 212 and another spring arm 213 correspondingly arranged at the front end of the fixing part, and an end foot 214 connected to the rear end of the fixing part. In this example, the fixing part 211 is a side-standing U-shaped body formed by stamping sheet metal. The spring arm 212 and the end foot 214 extend opposite to each other on the front and rear of the same side of the U-shaped body. The other spring arm 213 is symmetrically formed on the other side of the U-shaped body. The free ends of the spring arm 212 and the other spring arm 213 are respectively inclined inward to form a contact point 2121 and another contact point 2131. When in use, one contact 2121 and another contact 2131 abut against each other. Since one contact 2121 and the other contact 2131 are arc-shaped, the two arc-shaped ends curve outwards and combine to form an easy-to-connect figure-eight shape (not marked). In this example, when the terminal piece 20 is assembled on the insulator 10, one spring arm 212 and another spring arm 213 (also referred to as "corresponding spring arms") pass through the partition hole 14 and are positioned in the movable groove 1312, so that the figure-eight shape formed by the two arc-shaped ends is aligned to receive the flared mouth (i.e., the two outwardly curved arc-shaped ends receive the upper wall shielding surface and the lower wall shielding surface respectively), thereby guiding the straight plate terminal of the associated circular connector to be inserted and avoiding terminal damage caused by misinsertion.
[0021] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0022] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
