Description

Technical Field

[0001] This utility model relates to the technical field of cable connectors that prevent misconnection, and particularly to a cable connector that prevents misconnection. Background Technology

[0002] Existing anti-misconnection cable connectors, while designed for ease of use, are not compatible with various devices and are prone to incompatibility due to interface discrepancies. For example, Chinese patent disclosure "Anti-misconnection Cable Connector" (application number: CN202323055503.2) includes a housing and a cable. The housing has a terminal plug on its left side and a protective mechanism. This protective mechanism includes a magnetic coil one, fixedly connected to the left side of the housing; a magnetic coil two, attracted to the left side of the magnetic coil one; and a protective cover fixedly connected to the left side of the magnetic coil two. While this structure facilitates use, it is still incompatible with different devices and prone to incompatibility due to interface discrepancies, thus limiting its usability. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a cable connector that prevents reverse connection. By providing a connecting seat, a rotating groove, a fixing ring, a connecting rope, a connecting post, a connecting groove, a negative electrode plate, a separating ring, and a positive electrode plate, it is easy to physically prevent reverse connection of positive and negative electrodes. At the same time, it is easy to adapt to different devices through the connecting post, thereby improving the overall compatibility.

[0004] This utility model also provides a cable connector with the above-mentioned anti-misconnection feature, comprising: a connecting base, a rotating groove provided on the outer surface of the connecting base, a fixed ring rotatably connected in the rotating groove, a connecting rope fixedly connected to the side surface of the fixed ring, a connecting post fixedly connected to the end of the connecting rope away from the fixed ring, a connecting groove provided in the connecting post, a negative electrode plate provided on the inner wall of the connecting groove, a separator ring fixedly connected in the connecting groove, and a positive electrode plate provided on the inner side of the separator ring. The negative electrode plate, the separator ring, and the positive electrode plate are all annular. Through the above structure, it is easy to physically prevent reverse connection of positive and negative electrodes, and at the same time, it is easy to adapt to different devices through the connecting post, thus improving the overall compatibility.

[0005] According to the present invention, a cable connector for preventing misconnection is provided on the connector base, and a plug is inserted into the slot. The plug is fixedly connected to the side surface of the plug. The above structure facilitates the connection between the connector base and the plug.

[0006] According to the present invention, a cable connector for preventing misconnection is provided, wherein a cable is fixedly connected to the side surface of the connector seat, the cable is located at the end away from the connector post, and the cable is electrically connected to the slot. The above structure facilitates the determination of the cable position.

[0007] According to the present invention, a cable connector for preventing misconnection is provided, wherein a cover plate is rotatably connected to the connecting post, thereby preventing dust from entering the connecting post.

[0008] According to the present invention, in a cable connector designed to prevent misconnection, the length of the negative electrode is shorter than that of the positive electrode. This structure facilitates the separation of the outer negative electrode first and the inner positive electrode last when the cable is pulled out, thus avoiding sparks during plugging and unplugging.

[0009] According to the present invention, a cable connector for preventing misconnection is provided, wherein the retaining ring is made of rubber. The above structure facilitates the installation of the retaining ring in the rotating groove.

[0010] According to the present invention, a cable connector for preventing misconnection is provided, wherein the insertion post is trapezoidal. This structure facilitates the prevention of misconnection during insertion post installation.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model discloses a cable connector for preventing misconnection, comprising: a connecting base 1, a rotating groove 2 on the outer surface of the connecting base 1, a fixing ring 3 rotatably connected within the rotating groove 2, the fixing ring 3 being made of rubber, a connecting rope 5 fixedly connected to the side surface of the fixing ring 3, a connecting post 6 fixedly connected to the end of the connecting rope 5 away from the fixing ring 3, a connecting groove 11 within the connecting post 6, a negative electrode 12 disposed on the inner wall of the connecting groove 11, a separating ring 13 fixedly connected within the connecting groove 11, a positive electrode 14 disposed on the inner side of the separating ring 13, and a negative electrode 14 disposed on the inner side of the negative electrode 14. 2. Both the separator ring 13 and the positive electrode plate 14 are annular. The length of the negative electrode plate 12 is shorter than that of the positive electrode plate 14. The connector 1 is provided with a slot 9. A post 10 is inserted into the slot 9. The post 10 is trapezoidal and is fixedly connected to the side surface of the connector 6. A cover plate 8 is rotatably connected to the connector 6. An abutment 7 is fixedly connected to the end of the connector 6 away from the cover plate 8. The abutment 7 has the same diameter as the connector 1. A cable 4 is fixedly connected to the side surface of the connector 1. The cable 4 is located at the end away from the connector 6 and is electrically connected to the slot 9.

[0022] Specifically, rotate the fixing ring 3 to insert the trapezoidal pin 9 on the connecting post 6 into the slot 9, then open the cover plate 8 and insert the connector on the cable to be connected into the connecting groove 11 in the connecting post 6, so that the positive and negative terminals on the connector come into contact with the positive electrode plate 14 and the negative electrode plate 12 in the connecting groove 11 to achieve connection. At the same time, due to the influence of the separating ring 13, the connector is locked in the connecting groove 11, separating the positive and negative terminals. The connecting rope 5 fixes the connecting post 6 to prevent it from falling off.

[0023] Working principle: In use, first insert the pin 10 on the connecting post 6 into the slot 9, so that the abutment 7 fits with the connecting seat 1. Then open the cover plate 8 and insert the connector on the cable to be connected into the connecting groove 11. Since the negative electrode 12 and the positive electrode 14 are both wavy elastic sheets, they are connected after contacting the elastic sheet on the connector. At the same time, due to the influence of the separating ring 13, the connector is locked in the connecting groove 11, separating the positive and negative electrodes to ensure safety. When facing different interfaces, multiple fixing rings 3 can be fitted in the rotating groove 2, and the slots 9 in the connecting post 6 on each fixing ring 3 should be different.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
