Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an unbalanced connector with a grounding point capable of moving forward. Background Art

[0002] In the field of audio electrical connections, three-core electrical connectors and two-core electrical connectors are widely used. The existing three-core electrical connector is also called TRS three-core electrical connector, where T represents the bead head, R represents the ring rod, and S represents the grounding; the existing two-core electrical connector is TS two-core electrical connector. The sockets corresponding to TRS three-core electrical connectors and TS two-core electrical connectors cannot be identified from the appearance. If the TS two-core electrical connector is inserted into the socket corresponding to the TRS three-core electrical connector, it will cause the RS two-point short circuit and may cause damage to the equipment. At present, some equipment manufacturers in the market use the R ring point in the TRS three-point socket as the grounding point. Although this can correspond to the TS two-core electrical connector, it causes the R point of the regular TRS three-core electrical connector to be grounded, while the S point cannot be connected to the grounding point. Utility Model Content

[0003] The utility model provides an unbalanced connector with a grounding point that can be moved forward, which can solve the problem that the existing TRS three-contact socket in which the R ring point serves as the grounding point cannot be matched with a regular three-core electrical connector.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an unbalanced connector whose grounding point can be moved forward, comprising a grounding body, an insulating rod body connected to one axial end of the grounding body, a bead head connected to one axial end of the insulating rod body, an insulating boss arranged between the bead head and the insulating rod body, a grounding conductive ring sleeved on the outer side of the grounding body, the grounding conductive ring can be moved axially along the grounding body to abut against the insulating boss and block the insulating rod body, the insulating rod body can be blocked by the axial movement of the grounding conductive ring, and the R ring point is connected to the grounding body, so that the electrical connector can be smoothly connected to the ground when the R ring point serves as the grounding point.

[0005] Preferably, an external threaded portion is provided on the grounding body, and an internal threaded portion cooperating with the external threaded portion is provided on the inner side of the grounding conductive ring. The axial movement of the grounding conductive ring can be achieved by rotating the grounding conductive ring, and the movement distance can be determined according to the number of rotations. The grounding conductive ring will not move axially under the action of axial force, and the plug-in is reliable.

[0006] Preferably, the length of the external threaded portion is greater than the length of the insulating rod body, so as to ensure that the movement of the grounding conductive ring can cover and shield the insulating rod body.

[0007] Preferably, the inner wall of the grounding conductive ring and the outer wall of the grounding body are matched with each other by friction, so that the grounding conductive ring can move axially smoothly and maintain its position through friction resistance, and will not be easily driven to move axially by the external force of the socket.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The structure is simple. By setting a grounding conductive ring that can move axially along the grounding body, the insulating rod on the electrical connector can be in contact with the grounding body and grounded, so as to adapt to the matching use with the TRS three-contact socket or TS two-contact socket with the R ring point serving as the grounding point, thereby solving the problem of incompatibility.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1-2 As shown, the utility model solves the problem that the existing TRS three-contact socket with the R ring point acting as the grounding point cannot be matched with the regular three-core electrical connector, and provides the following technical solution: an unbalanced connector with a grounding point that can be moved forward, comprising a grounding body 3, an axial end of the grounding body 3 is connected to an insulating rod body 2, an axial end of the insulating rod body 2 is connected to a bead head 1, an insulating boss 6 is arranged between the bead head 1 and the insulating rod body 2, a grounding conductive ring 4 is sleeved on the outer side of the grounding body 3, the grounding conductive ring 4 can be moved axially along the grounding body 3 to abut against the insulating boss 6 and block the insulating rod body 2, the insulating rod body 2 can be blocked by the axial movement of the grounding conductive ring 4, and the R ring point is connected to the grounding body 3, so that the electrical connector can be smoothly connected and grounded when inserted into the TRS three-contact socket with the R ring point acting as the grounding point.

[0016] Specifically, the grounding body 3, the bead head 1 and the insulating rod body 2 are all coaxially arranged structures. The insulating rod body 2 is a cylinder with insulating material wrapped on the outside. The insulating boss 6 isolates the grounding conductive ring 4 from the bead head 1, so that the grounding conductive ring 4 cannot contact the bead head 1 no matter how it moves axially.

[0017] When the electrical connector in this embodiment needs to be inserted into a regular TRS three-contact socket, the grounding conductive ring 4 remains in place, does not move to the outside of the insulating rod body 2, and does not contact the insulating boss 6. The bead head 1, insulating rod body 2 and grounding body 3 on the electrical connector are respectively in contact with the corresponding contact points on the TRS three-contact socket.

[0018] When the electrical connector in this embodiment needs to be inserted into a TRS three-contact socket or a TS two-contact socket in which the R ring point serves as a grounding point, the grounding conductive ring 4 can be axially moved so that the grounding conductive ring 4 abuts against the insulating boss 6, and the grounding conductive ring 4 covers the area of ​​the insulating rod body 2. In this way, the grounding contact points in the TRS three-contact socket or the TS two-contact socket in which the R ring point serves as a grounding point can be connected to the grounding body 3, thereby ensuring effective grounding of the electrical connector.

[0019] In this embodiment, if Figure 1 As shown, the grounding body 3 is provided with an external threaded portion 5, and the inner side of the grounding conductive ring 4 is provided with an internal threaded portion matched with the external threaded portion 5. The grounding conductive ring 4 can be rotated to achieve axial movement, and the moving distance can be determined according to the number of rotations. The grounding conductive ring 4 will not move axially under the action of the axial force, and the plug-in is reliable. Among them, the length of the external threaded portion 5 is greater than the length of the insulating rod body 2, ensuring that the movement of the grounding conductive ring 4 can cover and shield the insulating rod body 2.

[0020] In this embodiment, as another moving cooperation mode of the grounding conductive ring 4, there is a resistance friction cooperation between the inner wall of the grounding conductive ring 4 and the outer wall of the grounding body 3, so that the grounding conductive ring 4 can move axially smoothly and maintain its position through friction resistance, and will not be easily driven to move axially by the external force of the socket.

[0021] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
