Description

Technical Field

[0001] The utility model belongs to the technical field of electric connectors, and in particular relates to an anti-loosening cable connector. Background Art

[0002] At present, after the plug and the socket are plugged in, although the two can cooperate stably, there is a defect in that the cable is not resistant to pulling. Although the electrical appliance usually does not loosen after being plugged in, as a mobile device for various operations, after being plugged in to the power source, the device will move, but the movement of the device will be accompanied by the pulling of the cable, which can easily cause the connector to loosen. For example, after a vacuum cleaner is plugged in to the plug, when the vacuum cleaner is manually driven to work indoors, the cable may occasionally become knotted or straightened and the plug may be pulled loose. Although this will not cause damage to the equipment, for some more expensive equipment, frequent sudden power outages may cause equipment damage and the like. At present, there are many types of anti-loosening electrical connectors, and the document number is CN219576099U "Anti-loosening electrical connector", which uses a pin to connect the connector male part and the connector female part to prevent the two from loosening. Although it has a good anti-loosening effect, it is inconvenient to use and the pin is easy to lose. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide an anti-loosening cable connector which has a simple structure, is easy to plug in, and has a good anti-loosening effect.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: an anti-loosening cable connector, comprising a connector mother and a connector male body, the connector mother body is in the shape of a slot body, and its slot chamber is a cylindrical cavity, the connector male body is cylindrical, and an electrical connection part is arranged on the inner bottom wall of the connector mother body at intervals in an annular direction, and one end of the connector male body is provided with a plurality of electrical connection ejectors distributed at intervals in an annular direction, and the plurality of electrical connection parts correspond to the plurality of electrical connection ejectors one by one, and a limiting protrusion is provided on the inner wall of the connector mother body slot, and the side wall of the connector male body is provided with a plurality of electrical connection ejectors distributed at intervals in an annular direction. A slide groove is arranged along its length direction, and the slide groove is bent at one end away from the electrical connection ejector pin to form a limiting groove. When the male connector is inserted into the female connector, the limiting protrusion is aligned with the slide groove and slides into the end of the slide groove, and the male connector is rotated relative to the female connector until the limiting protrusion enters the limiting groove to axially lock the male connector and the female connector. When the female connector and the male connector are axially locked, each of the electrical connection ejector pins contacts the corresponding electrical connection part to be electrically connected.

[0005] The beneficial effect of the utility model is that when the connector male and connector mother need to be plugged in, the slide groove on the connector male and the limiting protrusion on the connector mother are aligned, and then the connector male is inserted into the connector mother until the limiting protrusion is located at the end of the slide groove. At this time, the electrical connection pin has been in contact with the electrical connection part. At this time, the connector male can be manually rotated until the limiting protrusion is inserted into the limiting groove. At this time, axially pulling the connector male will not separate the connector male and the connector mother. If the two need to be separated, it is only necessary to rotate the connector male until the limiting protrusion moves to the end of the slide groove, and then pull the connector male until it is separated from the connector mother.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a partition plate is provided at the bottom of the groove of the connector mother body, and the partition plate divides the inner bottom wall of the connector mother body into a plurality of circumferentially distributed fan-shaped grooves, and the plurality of fan-shaped grooves correspond one by one to the plurality of electrical connection parts, and the electrical connection parts are respectively installed in the corresponding fan-shaped grooves.

[0008] The beneficial effect of adopting the above further solution is that the partition can form a partition between two adjacent electrical connection parts to avoid the two adjacent electrical connection parts from contacting each other and causing a short circuit.

[0009] Furthermore, the number of the electrical connection parts and the electrical connection pins is 2 or 3.

[0010] The beneficial effect of adopting the above further solution is that it can meet the use requirements of conventional equipment.

[0011] Further, the electrical connecting part includes a conductive sheet and a spring, one end of the conductive sheet is connected to one end of the bottom wall of the corresponding fan-shaped groove, the other end of the conductive sheet is tilted in the fan-shaped groove, and the spring is installed in the fan-shaped groove, one end of which is connected to the other end of the bottom wall of the fan-shaped groove, and the other end is connected to the tilted end of the conductive sheet. When the connector male body is inserted into the connector female body and the limiting protrusion is located at the end of the slide groove, the end of the electrical connection pin is against the end of the corresponding conductive sheet away from the corresponding spring. When the connector male body is rotated until the limiting protrusion is located in the limiting groove, multiple electrical connection pins are synchronously rotated to squeeze the corresponding spring and contact the tilted end of the corresponding conductive sheet.

[0012] The beneficial effects of adopting the above further solution are: its structure is simple, so that the electrical connection part has a buffering performance, and the conductive sheet is arranged obliquely and cooperates with the spring, so that the contact effect between it and the electrical connection pin is good.

[0013] Furthermore, the electrical connection pin is an elastic pin.

[0014] The beneficial effect of adopting the above further solution is that the electrical connection pin also has a buffering performance, which can further improve the contact effect between the conductive sheet and the electrical connection pin.

[0015] Furthermore, an annular limiting ring is protruded annularly on the side wall of the male connector away from one end of the electrical connection ejector pin, and after the male connector is plugged into the female connector, the limiting ring abuts against the notch of the female connector.

[0016] The beneficial effect of adopting the above further solution is that it allows the user to easily determine whether the limiting protrusion has slid to the end of the slide groove (when the notch end of the joint body abuts against the limiting ring, it means that the limiting protrusion is at the end of the slide groove).

[0017] Furthermore, it also includes a mounting plate, the joint mother body passes through the middle of the mounting plate, and a plurality of penetrating mounting holes are circumferentially spaced apart on the mounting plate.

In this way, when the connector male body and the connector mother body need to be plugged in, the slide groove on the connector male body is aligned with the limiting protrusion on the connector mother body, and then the connector male body is inserted into the connector mother body until the limiting protrusion is located at the end of the slide groove. At this time, the electrical connection pin has contacted the electrical connection part. At this time, the connector male body can be manually rotated until the limiting protrusion is inserted into the limiting groove. At this time, axially pulling the connector male body will not separate the connector male body and the connector mother. If the two need to be separated, it is only necessary to rotate the connector male body until the limiting protrusion moves to the end of the slide groove, and then pull the connector male body until it is separated from the connector mother.

[0036] like Figure 3-Figure 5 As shown, a partition plate 12 is provided at the bottom of the groove of the connector mother body 1 in the above technical solution, and the partition plate 12 divides the inner bottom wall of the connector mother body 1 into a plurality of circumferentially distributed fan-shaped grooves 13, and the plurality of fan-shaped grooves 13 correspond one by one to the plurality of electrical connection parts 3, and the electrical connection parts 3 are respectively installed in the corresponding fan-shaped grooves 13, so that the partition plate can form a partition between two adjacent electrical connection parts to avoid contact between the two adjacent electrical connection parts and cause a short circuit.
