Description

Technical Field

[0001] The utility model relates to the technical field of electronic industrial components, in particular to a connector with a hook. Background Art

[0002] Connectors, also known as electronic connectors, are a common connection component between two devices or two PCB boards. They are widely used, especially in the existing mainstream modular design standards. Connectors play a vital role because electronic products or equipment are mostly modular in design, each module implements different functions, and each module is interconnected with the host. The interconnection is generally achieved by connectors. Connectors are an important component in the electronics industry and play an increasingly important role in electronic equipment.

[0003] The most common connector is a male connector that is soldered on one end of the PCB board, and a female connector with a wire on the other end. The female connector is connected to the male connector, and then the other end of the female connector is also soldered on the PCB board, or the female connector is connected to a male connector that is soldered on another PCB board. To ensure a good connection between the module and the host, the quality of the connector connection directly determines the quality of the entire machine.

[0004] However, conventional connectors do not have a hook structure, and only rely on their own plug-in force to ensure the connection effect during the connection process. Especially when the number of PINs is relatively small (such as 2PIN), the plug-in force will also be relatively small. When the plug-in force is relatively small, the male and female heads are very easy to fall off after connection. After falling off, the module and the host cannot work normally, which will bring fatal quality risks to the product. Utility Model Content

[0027] In some embodiments, the female rubber core 6 is provided with a female rubber core end spring piece 17 corresponding to the female terminal 5 , and the female terminal 5 is provided with a female terminal limiting block 23 corresponding to the female rubber core end spring piece 17 .

[0028] In some embodiments, the number of the female rubber core clamping points 18 and the number of the male rubber core spring pieces 10 are the same, and the number of both is greater than or equal to 2.

[0029] In some embodiments, a female rubber core anti-idiot block 19 is provided on the female rubber core 6 , and a male rubber core anti-idiot groove 11 matching the female rubber core anti-idiot block 19 is provided on the male rubber core 4 .

[0030] In some embodiments, a female rubber core anti-idiot block 19 is provided on the female rubber core 6 , and a male rubber core anti-idiot groove 11 matching the female rubber core anti-idiot block 19 is provided on the male rubber core 4 .

[0031] In some embodiments, the male rubber core guard frame 8 is provided with a male rubber core guard frame chamfer 9 for guiding.

[0033] In some embodiments, the male rubber core 4 is provided with a male rubber core positioning column 13 for welding positioning.

[0034] In some embodiments, the electric wire 7 includes a wire copper wire 26 and a wire sheath 27 , and the female terminal 5 is provided with a female terminal copper wire clamp 24 for covering the wire copper wire 26 and a female terminal sheath clamp 25 for covering the wire sheath 27 .

[0035] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage.

[0036] In specific use, such as Figure 2-3 As shown, a connector with a hook according to the utility model includes a male head 1 and a female head 2, wherein the male head 1 includes a male rubber core 4 and a male terminal 3, and the female head 2 includes a female rubber core 6, a female terminal 5 and an electric wire 7. The assembly can be completed after the male terminal 3 is inserted into the male rubber core 4. After the female terminal 5 is wired, the copper wire 26 of the electric wire is wrapped by the copper wire wire clamp 24 of the female terminal, and the outer skin 27 of the electric wire is wrapped by the outer skin wire clamp 25 of the female terminal.

[0037] Then insert the wired female terminal 5 into the female rubber core PIN hole 16 together. When the female terminal 5 passes through the female rubber core end spring clip 17, the female rubber core end spring clip 17 bounces up, and then the female terminal 5 smoothly passes through the female rubber core end spring clip 17. After passing through the female rubber core end spring clip 17, it will return to its original position, thereby jamming the female terminal limit block 23 to achieve the purpose of limiting the female terminal 5 to withdraw backward.

[0038] In order to cooperate well with the female head 2, a male rubber core protection frame 8 is designed around the male rubber core 4. When the female head 2 is inserted into the male rubber core 4, the male rubber core protection frame 8 surrounds the female rubber core protection wall 15. Under the protection of the male rubber core protection frame 8, the female head 2 can be prevented from swinging left and right and causing unstable contact. In order to facilitate the insertion of the female head 2, a male rubber core protection frame chamfer 9 is designed on the male rubber core 4. The male rubber core protection frame chamfer 9 has a guiding function, which is conducive to the smooth insertion of the female head 2 into the male head 1, thereby improving the insertion efficiency.

[0039] In order to further improve the product plug-in quality and prevent the wrong plug-in direction, a female rubber core 6 is designed with a female rubber core anti-mistake block 19, and a male rubber core anti-mistake groove 11 is designed on the male rubber core 4. When the male head 1 and the female head 2 are plugged in, they can only be inserted if the directions of the female rubber core anti-mistake block 19 and the male rubber core anti-mistake groove 11 are consistent. Otherwise, they will not be able to be plugged in, thereby protecting the male and female heads from the quality risk of burning the board due to the line sequence error caused by the wrong plug-in direction, so as to improve the connection reliability of the male and female heads.

[0040] A female rubber core clamping point 18 is designed on the female rubber core 6, and a male rubber core spring piece 10 is designed on the male rubber core 4. When the female head 2 and the male head 1 are fully inserted, the female rubber core clamping point 18 on the female rubber core 6 will hook the male rubber core spring piece 10 on the male rubber core 4, thereby increasing the connection tension between the male head 1 and the female head 2, to ensure that the male and female heads are not easily removed when connected, especially in complex environments such as vibration caused by external forces.

[0041] A female rubber core hook 22 is also designed on the female rubber core 6, and a male rubber core block 14 is designed on the male rubber core 4. The female rubber core hook 22 has an elastic function under the action of the female rubber core key support block 20. When the female head 2 is fully inserted into the male head 1, the female rubber core hook 22 will hook the male rubber core block 14, which will greatly increase the overall pulling force when the male and female heads are connected, so that the female head is not easy to fall off from the male head.

[0042] Since the female rubber core hook 22 has an elastic function, when the female rubber core hook button 21 is pressed, the female rubber core hook 22 will bounce up. After bouncing up, the female rubber core hook 22 will be separated from the male rubber core block 14. Continue to pull back to complete the separation of the female head 2 and the male head 1, thereby realizing the removal of the female head 2 from the male head 1.

[0043] There are several ways to install the male connector 1 on the PCB board, including SMT reflow soldering (the needle tail is an SMT bent foot), through-hole wave soldering (the needle tail is a straight foot), etc. In order to improve the welding quality, the male plastic core 4 is also designed with a male plastic core anti-seepage tin rib 12. During welding, the tin may flow to both sides. The male plastic core anti-seepage tin rib 12 can prevent the tin from flowing to the adjacent male terminal 3, thereby preventing the occurrence of a short circuit.

[0044] In addition, in order to ensure good positioning before welding, a male rubber core 4 is also designed with a male rubber core positioning column 13. Under the action of the male rubber core positioning column 13, the entire product will not be able to move at will, thereby achieving accurate positioning.

[0045] To sum up, with the help of the above-mentioned technical scheme of the utility model, through the optimization and improvement design of the product of the utility model, the connection of the connector is stable and reliable, providing the device with better contact force and conductivity to ensure stable signal transmission, thereby achieving the technical effect of improving the operating quality of electronic equipment, and effectively reducing the impact of complex environmental conditions such as vibration and impact on the connection stability of electronic equipment.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
