Description

Board-end connectors, wire-end connectors and their combinations

The present invention relates to a board-end connector, a wire-end connector and a combination thereof, and in particular to a wire-end connector whose shielding shell is made of a metal plate and has a locking spring extending therefrom. When the board-end connector and the wire-end connector are mated, the locking spring can be buckled into the buckle hole of the positioning shell of the board-end connector in an elastically deformed manner, and a drawstring is provided on the top side of the locking spring to make it easier for the user to perform plugging and unplugging operations, thereby forming an electrical connector that is not easily loosened by external force impact, is easy to assemble, and has a low assembly height.

According to the current rapid growth and maturity of the electronics industry, many different 3C functional electronic products are developed and manufactured according to different needs, especially computers, laptops, tablets and smart phones, the speed of overlap is beyond imagination, and the direction of update is nothing more than processor computing speed, network transmission speed and lighter, thinner, shorter and smaller size. In addition to the smaller size, electronic products also need to be equipped with different interface connectors to cope with the expansion of more functions.

In recent years, electrical connectors have been widely used in various electronic devices. However, in response to the trend of electronic devices becoming thinner and lighter, the size of electrical connectors has been continuously reduced, which not only increases the difficulty of processing, but also weakens the structural strength. The wire-to-board connector assembly will have components such as board terminals, wire terminals, and insulating rubber seats. At present, electrical connector components are usually assembled to complete the combination with each other, but if the size of electronic products continues to decrease, the space available for assembly between electronic products will also be reduced, and the size of the connector will also be reduced. It is becoming increasingly difficult to assemble the connector in the assembly space, resulting in insufficient structural strength of the assembled connector, which makes it difficult to improve assembly speed and efficiency. On the other hand, when the electrical connector containing the cable is combined with the board-end connector for assembly, due to the flexibility of the cable, when the conductive terminal provided on the cable is connected with the docking terminal of another connector, it is very easy to cause misalignment and thus affect the transmission of electronic signals. Therefore, how to improve the above-mentioned defects, thereby simplifying the installation procedure of the connector, and improving the structural strength of the connector, and solving the misalignment problem between the two electrical connectors. At the same time, the electrical connector containing the cable and the board-end connector are difficult to disassemble or cannot be disassembled after assembly, which increases the difficulty of electronic product maintenance. Regarding the above-mentioned problems, it is necessary for people in the relevant technical field to propose solutions.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information and, after multiple evaluations and considerations, designed this board-end connector, line-end connector and their combination.

The butt joints of the conductive terminals are electrically connected to the contact terminals, and the conductive terminals are welded with a plurality of cables at one end away from the butt joints. A receiving portion having a receiving groove inside and received in the receiving cavity is protruded from one side of the insulating body; a shielding shell has a receiving chamber inside for assembling the insulating body and a locking spring sheet extending downward from the top surface and received in the receiving groove, and a mutual locking structure is provided between the locking spring sheet and the locking frame. The aforementioned shielding shell is made of metal plate and has a locking spring extending therefrom. When the board-end connector and the wire-end connector are mated, the locking spring can be buckled into the buckle hole of the positioning shell of the board-end connector in an elastically deformed manner. A pull strap is provided on the top of the locking spring, which makes it easier for users to perform plugging and unplugging operations, and forms an electrical connector that is not easily loosened by external impact, is easy to assemble, and reduces the assembly height.

The secondary purpose of the present invention is that the side plates on both sides of the positioning housing are further formed with a buckle piece that is clamped in the buckle holes on both sides of the shielding housing. When the board-end connector and the wire-end connector are matched, the buckle piece and the buckle hole design on the left and right sides make the two metal parts of the positioning housing and the shielding housing cooperate with each other, thereby suppressing the torsional force of the cable's own flexibility on the electrical connector.

Please refer to Figures 1 to 3, which are the three-dimensional appearance diagram, three-dimensional exploded diagram and three-dimensional exploded diagram from another perspective of the board-end connector and the wire-end connector of the present invention after assembly. It can be clearly seen from the figure that the board-end connector, wire-end connector and their combination of the present invention mainly include a board-end connector 1, a wire-end connector 2, a cable 3 and a drawstring 4, and the detailed structure and connection relationship of the above are as follows:

The board-end connector 1 includes a base 11, a slot 110 is recessed inside the base 11, and a plurality of contact terminals 111 are provided on both sides of the slot 110.

The two ends of the positioning housing 12 are each formed with a side plate 121 fixed to the two sides of the base 11, and the positioning housing 12 is bent corresponding to one side of the base 11 to form a locking frame 122 with a storage cavity 1220 inside.

The wire end connector 2 includes an insulating body 21 and a tongue plate 211 connected to the slot 110 is protruded from the bottom side of the insulating body 21. A plurality of conductive terminals 212 are penetrated on at least one side of the tongue plate 211 and the connecting portions 2121 of the conductive terminals 212 are electrically connected to the contact terminals 111. The conductive terminals 212 are welded with a plurality of cables 3 at one end away from the connecting portion 2121. A receiving portion 213 having an accommodating groove 2131 inside and received in the receiving cavity 1220 is protruded from one side of the insulating body 21.

The shielding shell 22 has a storage chamber 220 for assembling the insulating body 21 and a locking spring 221 extending downward from the top surface and received in the receiving groove 2131. The locking spring 221 and the locking frame 122 have a mutual locking structure.

Please refer to Figure 6 at the same time. The side panels 121 on both sides of the positioning housing 12 are further formed with a buckle 1211 that is clamped to the buckle holes 222 on both sides of the shielding housing 22. When the board-end connector 1 and the wire-end connector 2 are matched, the buckle 1211 and the buckle holes 222 are designed on the left and right sides to make the two metal parts of the positioning housing 12 and the shielding housing 22 cooperate with each other, thereby suppressing the torsional force of the cable 3 itself on the electrical connector. The bottom side of the positioning housing 12 further protrudes downward with a plurality of plug pins 123 that are plugged into and positioned in a through hole of a preset circuit board (not shown in the figure).

The locking spring 221 includes a connecting portion 2211 extending downward from the top of the shielding shell 22. The connecting portion 2211 extends upward from the outside through two bent portions 2212 to form a movable portion 2213. The two bent portions 2212 have a positioning edge 2214 between them. A rotation space 221 is formed between the movable portion 2213 and the connecting portion 2211. 0, and the movable part 2213 is provided with at least one buckle block 2215 protruding outwardly and buckled in the buckle hole 1221 of the locking frame 122, and the top side of the movable part 2213 is provided with a strap hole 2216 for tying one end of the drawstring 4, and the other end of the drawstring 4 is downwardly passed through a strap hole 223 provided on the top surface of the shielding shell 22 to form a positioning.

The insulating body 21 is provided with a fixing plate 214 corresponding to the position where the cables 3 are passed through. The fixing plate 214 can be used to fix the cables 3 divided into upper and lower rows, and the cables 3 in the upper and lower rows are welded to the welding parts 2122 of the conductive terminals 212 distributed on both sides of the tongue plate 211. The bottom side of the receiving groove 2131 of the insulating body 21 is further provided with a positioning block 2132 for the positioning edge 2214 of the locking spring 221 to be abutted and positioned, and the top side of the receiving groove 2131 has an opening 2133 for the locking spring 221 to pass downward.

Please refer to Figures 4 and 5, which are side cross-sectional views of the board-end connector and the line-end connector of the present invention before and after unlocking. First, the base 11 of the board-end connector 1 and the positioning housing 12 need to be assembled through a preset bending jig (not shown in the figure), and then the board-end connector 1 and the preset circuit board are plugged and soldered; at the same time, the insulating body 21 of the line-end connector 2 and The shielding shell 22 is assembled by a preset bending jig, and the plurality of cables 3 are inserted into the fixing plate 214 for fixing, and the plurality of internal cores are respectively welded to the welding parts 2122 of the plurality of conductive terminals 212, and the drawstring 4 is first inserted into the belt hole 223 of the shielding shell 22, and then the end of the drawstring 4 is tied to the tie hole 2216 of the locking spring 221 to form a positioning. Then, the tongue plate 211 of the line end connector 2 is inserted downwardly into the slot 110 of the board end connector 1, so that the connecting part 2121 of the plurality of conductive terminals 212 of the line end connector 2 and the plurality of contact terminals 111 of the board end connector 1 form an electrical connection. At the same time, the receiving portion 213 of the insulating body 21 and the locking spring sheet 221 of the shielding shell 22 are received in the receiving cavity 1220 of the positioning shell 12. When the wire end connector 2 is pushed downward, the buckle block 2215 located at the locking spring sheet 221 first abuts against the upper edge of the locking frame 122 so that the movable portion 2213 rotates toward the connecting portion 2211 and the rotation space 2210 is compressed. After the buckle block 2215 slides into the buckle hole 1221 of the locking frame 122, the elastic restoring force of the movable portion 2213 causes the top surface of the buckle block 2215 to abut against the top side of the buckle hole 1221 to form a locked state. On the other hand, when the board-end connector 1 and the wire-end connector 2 are mated, the buckle pieces 1211 and buckle holes 222 are designed on the left and right sides to make the two metal parts of the positioning shell 12 and the shielding shell 22 cooperate with each other, thereby suppressing the torsional force of the cable 3 itself on the electrical connector to form a stable locking structure.

As described above, when the wire-end connector 2 is to be unlocked and separated from the board-end connector 1, the end of the drawstring 4 must be clamped and pulled outward horizontally, and the movable portion 2213 of the locking spring 221 is rotated toward the connecting portion 2211 and the rotation space 2210 is compressed. At this time, the top surface of the buckle block 2215 has completely separated from the buckle hole 1221 to form In the unlocked state, the drawstring 4 is pulled vertically upward to drive the wire end connector 2 upward at the same time. The buckle pieces 1211 on the left and right sides of the board end connector 1 and the wire end connector 2 are supported by the upper edge of the buckle hole 222 and bounce outward to form an unlocked state, and the wire end connector 2 is separated from the board end connector 1, thereby completing the purpose of separating the two.

The main technical feature of the present invention is that the shielding shell 22 of the wire end connector 2 is made of metal plate and extends with a locking spring 221. The locking spring 221 can be buckled into the buckle hole 1221 of the positioning shell 12 of the board end connector 1 in an elastic deformation manner when the board end connector 1 and the wire end connector 2 are matched. A pull strap 4 is provided on the top side of the locking spring 221, which allows users to perform plugging and unplugging operations more easily, and forms an electrical connector that is not easily loosened by external impact, is easy to assemble, and reduces the assembly height. The present invention is applied in the field of electrical connectors where the wire end is matched with the board end, and has excellent practicality, so a patent application is filed to seek patent protection.

The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.

In summary, the board-end connector, wire-end connector and their combination of the present invention can achieve their efficacy and purpose when used, so the present invention is truly a creation with excellent practicality. In order to meet the application requirements of invention patents, an application is filed in accordance with the law. I hope that the review committee will approve this case as soon as possible to protect the inventor's hard work.
