Description

Pull belt type connector structure

Technical Field

The present invention relates to a connector structure, and more particularly to a drawstring connector structure.

Background

In general, the male and female connectors of an electronic product are prevented from being separated from each other by the locking structure, and therefore, the locking structure needs to be separated by pressing when the connector is disassembled. With the rapid development of technology, electronic products are also miniaturized and lightened, so that the distance between each electronic component and the connector in the circuit board is smaller and smaller. Therefore, a drawstring connector is derived, which can separate the lock catch structure by pulling the drawstring, so as to save the space required by the original press type connector.

In general, the conventional drawstring connector fixes the drawstring to a locking fastener, so that the locking fastener can be driven to separate from the locking structure when the drawstring is pulled. However, since the pull strap is integrally formed by plastic, the force is directly transmitted to the latch structure when pulling the pull strap, which results in poor hand feeling when pulling the pull strap and is troublesome in the manufacturing process, and therefore, how to make the pull strap have better hand feeling when pulling the pull strap and easy to manufacture is a drawback to be improved.

In view of the above, the present invention is directed to a method for solving the above-mentioned problems, which is an improved object of the present invention.

Detailed Description

The detailed description and technical contents of the present invention will be described below with reference to the drawings, however, the drawings are only for illustrative purposes and are not intended to limit the present invention.

The present invention provides a drawstring connector structure, as shown in fig. 1 to 3, including a main housing 10, a connector body 20, a locking fastener 30, a drawstring 40, a pair of housings 50 and a movable press rod 60.

The main housing 10 is formed by injection molding of plastic, and is provided with a plurality of first fastening structures 11. The connector body 20 is accommodated in the main housing 10, and includes a gold finger end 21, an insulating housing 22 and a plurality of wires 23. A gold finger tip 21 is formed extending from the insulative housing 22. Each wire 23 is electrically connected to the gold finger tip 21, and the connection portion between each wire 23 and the gold finger tip 21 is covered by the insulating housing 22. The locking fastener 30 is formed by injection molding of plastic. A plurality of second fastening structures 31 are provided and a pulling portion 32 is formed by extending. Each second fastening structure 31 is fastened corresponding to each first fastening structure 11. The pulling portion 32 has two elongated notches 321. The drawstring 40 is made of elastic material such as rubber, and has a fitting portion 41 for fitting each elongated notch 321. The sub-housing 50 is formed by injection molding of plastic, and is assembled with the main housing 10 to sandwich the connector body 20. The sub-housing 50 is formed with a pair of slide grooves 51 in cooperation with the main housing 10 in the extending direction of the gold finger tip 21. The movable pressing rod 60 is made of metal or plastic. The drawstring 40 is pressed by the movable pressing rod 60, and two ends of the movable pressing rod 60 are movably accommodated in the sliding grooves 51 respectively.

Further, an insertion groove 12 is formed at the top of the main housing 10, and the locking fastener 30 is attached to the insertion groove 12, so that the locking fastener 30 can be limited in the left-right direction and the up-down direction. A cover plate 121 is formed on each of the left and right sides of the insertion groove 12, and each cover plate 121 covers each of the left and right sides of the pulling portion 32. Thereby, the up-and-down direction of the pulling part 32 can be limited. In this embodiment, each of the first fastening structures 11 is a protruding fastening block, and each of the second fastening structures 31 is a fastening hole. However, the present invention is not limited to this, for example, the first fastening structure 11 may also be a fastening hole, and the second fastening structure 31 may also be a convex fastening block. Thereby, the front and rear direction of the locking fastener 30 can be limited.

The sub-housing 50 is formed at the top with a groove 52, and the pull belt 40 is movably disposed between the groove 52 and the movable pressing rod 60 back and forth. The width of the drawstring 40 is smaller than the width of the groove 52, thereby achieving the effect of limiting the left and right directions of the drawstring 40. And because the drawstring 40 is vertically constrained between the movable pressing rod 60 and the groove 52, when the drawstring 40 is pulled, the drawstring 40 takes the movable pressing rod 60 as a fulcrum, and the pulling part 32 is pulled downwards.

To explain, two sides of the main housing 10 are respectively provided with a locking hole 13, two sides of the sub-housing 50 are respectively provided with a locking hook 53 and a pushing portion 54 formed at the front end of the locking hook 53, and two sides of the insulating housing 22 are respectively formed with a stop block 221. The hooks 53 are engaged with the engaging holes 13 to fix the sub-housing 50 in the main housing 10. The pushing portions 54 of the sub-housing 50 are used to stop against the stop blocks 221 of the insulating housing 22, so as to prevent the connector body 20 from being separated from the main housing 10 and the sub-housing 50.

Please refer to fig. 4 and 5, which are sectional side views of the pulling belt 40 pulling forward and backward when the present invention is inserted into the corresponding female connector a. The female connector A has at least one locking hole A1, and the locking fastener 30 has at least one buckle 322 formed on the pulling portion 32. The utility model discloses with when the female A of connector is pegged graft, buckle 322 is detained and is established in hasp hole A1, as shown in figure 4. When the pulling strip 40 is pulled backward, the pulling strip 40 pulls down the driving portion 32 of the locking fastener 30 using the movable pressing rod 60 as a fulcrum, so that the buckle 322 on the driving portion 32 is separated from the locking hole a1 of the connector female head a, as shown in fig. 5.

Of course, the present invention can have other embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the claims of the present invention.
