Description

The present invention relates to an improved connector structure, and more specifically, it can effectively prevent two connected connectors from being detached from the screen, connecting electrical conductors, connecting electrical signal lines, and the like. The present invention relates to an improved connector structure applicable to the connection of electric wires.

With the rapid development of science and technology, various advanced and convenient appliances have been used in large quantities. In order to ensure the normal operation of these electric appliances, it is necessary to supply highly reliable power and control signals. Ordinarily, the power plug of the appliance may be inserted directly into a city outlet or connected to the power supply of another appliance through two interconnected connectors. The control signal can also supply electricity in a manner that combines two connectors. Traditional methods simply plug the plug into an outlet or connect two connectors to provide electricity. Since such a connector is not protected at all, when a lead wire (for example, a cord) is entangled with carelessness, the connection between the plug and the outlet or both connectors is detached, Electricity supply is interrupted and inconvenient.

For this reason, various connector dropout prevention devices have been devised. For example, there is “Connector drop prevention structure” of Taiwan Patent No. M372572, “Improved Fast Connector Structure” of Taiwan Patent No. M353286, etc. The purpose is to prevent separation. However, the above connector detachment preventing device generally has too many components and is difficult to assemble, so it is not ideal.

In view of the above circumstances, the present inventors have been able to improve the structure of the improved connector according to the present invention, which can be used with peace of mind by consumers as a result of many years of hard work. It is.

Taiwan Patent No. M372572 Taiwan Patent No. M353286

The main object of the present invention is to provide an improved connector structure that is simple, sophisticated and convenient to use with few parts.

The next purpose of the present invention is to provide an improved connector structure that can prevent the connector from being detached when an electric wire or cord is inadvertently caught.

In order to achieve the above object, the improved connector structure according to the present invention consists of two interconnected connectors with anti-play devices. A protective jacket is gently placed on the outer edge of one of the connectors, and at least one open slot is formed in the vertical direction at the inlet end of the jacket. The open slot extends inward and forms one folded corner. Correspondingly, the same number of studs as the open slots protrude from the outer edges of the other connectors. Joining the two connectors together and screwing the jacket over, and sliding the studs along the open slots and mating together will certainly prevent accidental detachment of the two connectors.

In the improved connector structure described above, two open slots are provided opposite to the inlet end of the protective jacket.

The open slot of the protective jacket of the improved connector structure described above extends a certain distance downward and then extends laterally to form a folded corner.

In the improved connector structure described above, a single hole is provided in the bottom edge of the folded corner of the open slot of the protective jacket to provide elasticity.

It is a three-dimensional external view of the Example of this invention. It is a component exploded view of the Example of this invention. It is operation explanatory drawing of the Example of this invention. It is operation explanatory drawing in the other Example of this invention.

For other features and advantages of the present invention, please refer to the description of the embodiments of the present invention with reference to the following drawings.

Refer to FIG. 1 and FIG. The improved connector structure according to the present invention includes a male connector 10, a female connector 20, and a protective jacket 30 that are coupled to face each other. On the periphery of the connecting terminal 11 of the male connector 10, a play prevention protrusion 12 is provided in the same direction, and there is one mark 14 on the surface of the plastic material of the male connector 10, and this mark 14 is the play prevention protrusion 12 Points to the position where is installed. On the plastic material of the male connector 10, one stud 13 is formed on each opposite side surface near the coupling terminal 11.

The terminal lug 21 of the female connector 20 is recessed in the plastic material, and one play prevention recessed tank 22 is provided in the peripheral direction of the terminal lug 21 in the direction of the vertical axis, and the female connector 20 On the upper surface of the plastic material, there is provided a mark 23 pointing to one concave tank 22 for preventing play.

The protective jacket 30 is in the form of one short hollow tube, and at least one open slot 32 is opened vertically at the edge of one end thereof. In this embodiment, two open slots 32 are opened at opposite positions. The open slot 32 is once recessed vertically by one short distance and then extended in the lateral direction. One folding corner portion 321 is formed. Further, an opening 31 for providing one more elasticity is provided at the bottom edge portion of the folded corner portion 321.

The jacket 30 is placed over the female connector 20 in a loose state. As shown in FIG. 3, the mark 14 of the male connector 10 and the mark 23 of the female connector 20 are provided opposite to each other, and the play preventing projection 12 on the coupling terminal 11 is provided with the play preventing concave tank 22 of the terminal lug 21. And must correspond. Since the protective jacket 30 is loosely attached, the open slot 32 on it is not necessarily exactly at the position corresponding to the stud 13 of the male connector 10, so the jacket 30 is turned, Align the position of the open slot 32 and the stud 13, apply force to the male connector 10, and fit the connecting terminal 11 and the two studs 13 to the open slot 32 of the terminal lug 21 and the jacket 30, respectively. Further, the jacket 30 is turned, and the stud 13 is brought into contact with the folded corner portion 321 of the open slot 32 in the lateral direction to complete the connector detachment preventing device.

The protective jacket 30 is not necessarily limited to being provided on the female connector 20, but may be provided on the male connector 10. Even if two studs 13 are provided on the front edge of the plastic material of the female connector 20, and the mark 23 is provided on the front edge of the mark 14 of the male connector 10, the effect of preventing the connector from being detached is also obtained. Can be achieved.

The above detailed description is a specific description of the feasible embodiments of the present invention. However, these embodiments do not limit the scope of claims of the present invention, and all implementations or modifications of equivalent effects made without departing from the technical spirit of the present invention are included in the scope of claims of the present invention.
