Description

Technical Field

[0001] This utility model relates to a male electrical connector, and more particularly to a male electrical connector that can be pulled and unlocked. Background Technology

[0002] The male electrical connector is mainly inserted by the user into the female electrical connector to complete the connection, such as... Figure 6A As shown, a male cable connector 60 has an elastic pressing piece 62 extending upward and backward from the top surface of its insulator 61. A locking element 621 is formed on this elastic pressing piece 62. To insert a mating female cable connector (not shown) fixed to a circuit board, the user's finger 70 presses the elastic pressing piece 62 downward. Figure 6B As shown, the locking piece 621 on it is moved down until it is fully inserted into the female electrical connector and then released. When the locking piece is reset, it engages the locking groove of the female electrical connector and is in an inserted and locked state. Conversely, to remove the male electrical connector, press down on the elastic pressing piece with your finger to move the locking piece down and unlock it, so that it can be pulled out from the female electrical connector.

[0003] However, as computer devices become increasingly smaller, the user's handheld male electrical connector is difficult to move within a limited space, especially since unlocking and unplugging takes a lot of time, so further improvements are necessary. Summary of the Invention

[0004] Given that manual unlocking male electrical connectors have limitations in certain products, the main objective of this invention is to provide a pull-to-unlock male electrical connector.

[0005] The main technical means used to achieve the above objectives include the following in the pull-to-unlock male electrical connector:

[0006] An insulating body has a pressing spring integrally formed on its top surface facing upward and backward, and the pressing spring forms a transverse through hole;

[0007] Multiple metal terminals are respectively disposed within the insulating body;

[0008] A metal plate, fixed to the top surface of the insulating body and positioned below the pressing spring, the metal plate extending rearwards into a limiting ring away from the rear side of the insulating body; and

[0009] One pull belt includes:

[0010] A retaining ring passes through the transverse through-hole of the pressing spring in the insulating body to fasten to the pressing spring; and

[0011] A belt, located on the rear side of the insulating body, passes through the limiting ring of the metal plate and is connected to the buckle; wherein when the belt is pulled backward, the buckle is activated and pulls down the pressing spring.

[0012] As described above, the pull-to-unlock male electrical connector of this utility model mainly has a metal plate fixed on its insulating body, with a limiting ring extending backward from the metal plate. This ring, combined with the transverse through-hole of the pressing spring on the insulating body, allows a pull strap to pass through the limiting ring and engage the pressing spring. Thus, when the user pulls the pull strap, the limiting ring converts the backward pulling force into a downward pulling force on the pressing spring, causing it to move downward and release the original locking state with the female electrical connector's outer shell slot, achieving the purpose of pull-to-unlock. Therefore, the male electrical connector of this utility model can be unlocked by hand or by pulling.

[0013] The above description is merely an embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above by way of embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.

[0042] This utility model relates to an improvement of a manually unlockable male electrical connector. The following embodiments, together with accompanying drawings, illustrate the technical content of this utility model in detail.

[0043] Please refer to the following first. Figure 1The image shows an embodiment of the male electrical connector 1 of this utility model, which is used as a male electrical connector for a cable, and the male electrical connector 1 is inserted into a mating female electrical connector 50. Please refer to further details. Figure 2 As shown, the male electrical connector 1 includes an insulating body 10, multiple metal terminals 15, a metal plate 30, and a pull strap 40.

[0044] The aforementioned insulating body 10 has a pressing spring 20 integrally formed on its top surface 11 extending upward and backward; preferably, the pressing spring 20 is located at the middle position of the top surface 11 of the insulating body 10. In this embodiment, the pressing spring 20 integrally includes a bent vertical portion 21, a horizontal portion 22, a pressing portion 23, and a latching member 221 extending upward and backward from the top surface 11 of the insulating body 10. The bent upright portion 21 is integrally bent upward from the top surface 11 of the insulating body 10 and is located near a front side 13 of the insulating body 10; the transverse portion 22 extends rearward from the bent upright portion 21; the pressing portion 23 extends upward from the transverse portion 22, and a transverse through hole 231 is formed at its junction with the transverse portion 22; the latching member 221 extends upward from the transverse portion 22, is located in front of the transverse through hole 231, and is lower in height than the pressing portion 23, so as to engage with the slot 52 of the housing 51 of the female electrical connector 50. Please also refer to... Figure 3A and Figure 3B The top surface 11 of the insulating body 10 is further formed with two first top protrusions 111 and a second top protrusion 112, the second top protrusion 112 being located between the two first top protrusions 111; preferably, the second top protrusion 112 is located in the middle of the top surface 11. Furthermore, a slot 131 is formed on the front side 13 of the insulating body 10, and two opposite sides 14 extend outward integrally with a side protrusion 141, a baffle 121 being formed behind the two side protrusions 141.

[0045] The aforementioned multiple metal terminals 15 are respectively disposed within the insulating body 10 to contact the corresponding metal terminals 53 of the female electrical connector 50.

[0046] The aforementioned metal plate 30 is fixed to the top surface 11 of the insulating body 10 and positioned below the pressing spring 20. The metal plate 30 extends rearward to a limiting ring 32 away from the rear side 12 of the insulating body 10. In this embodiment, the rear half of the limiting ring 32 is inclined upwards. The metal plate 30 integrally comprises a plate body 31, a front claw portion 33, and two side claw portions 34. The plate body 31 is fixed to the top surface 11 of the insulating body 10, and its rear side is integrally connected to the limiting ring 32. The front claw portion 33 integrally extends from the front side of the plate body 31, passes through the bent upright portion 21 of the pressing spring 20 and the junction with the insulating body 10, and matches and engages with the slot 131 of the insulating body 10. Figure 4As shown, the two claw portions 34 are integrally connected to the two opposite sides of the plate body 31 and are matched and fastened to the two protrusions 141 of the insulating body 10.

[0047] To more stably fix the metal plate 30 to the top surface 11 of the insulating body 10, for example... Figure 5 As shown, the plate body 31 forms two first engaging grooves 311 corresponding to the two first top protrusions 111 on the insulating body 10, for the two first top protrusions 111 to be matched and engaged; and as... Figure 3A As shown, the plate body 31 forms a second engaging groove 313 corresponding to the second top protrusion 112 on the insulating body 10, for the second top protrusion 112 to engage. In one embodiment, each of the first top protrusions 111 is a T-shaped protrusion. For example... Figure 5 As shown, each of the first top protrusions 111 has a recess 113 formed on its two opposite sidewalls to cooperate with the two flanges 312 of the two opposite groove walls of each of the first engaging grooves 311. The flanges 312 are respectively engaged in the two recesses 113.

[0048] Please refer to the following: Figure 2 and Figure 3A The aforementioned pull strap 40 includes a buckle 41 and a strap body 42. The buckle 41 passes through the transverse through hole 231 of the pressing spring 20 of the insulating body 10 to fasten to the pressing spring 20, while the strap body 42 is located on the rear side 12 of the insulating body 10, passes through the limiting ring 32 of the metal plate 30 and is connected to the buckle 41.

[0049] like Figure 1 and Figure 3A As shown, when the male connector 1 is inserted into the female connector 50, its locking mechanism engages with the slot 52 of the housing 51 of the female connector 50, thus locking the connector. When the male connector 1 and the female connector 50 are positioned in a location difficult for the user to reach, the user can... Figure 3B As shown, when the belt 42 is pulled, the buckle 41 is activated and pulls down the pressing spring 20, causing the buckle 221 on it to stop moving as before. Figure 3A The male connector 1 is inserted into the slot 52 of the female connector 50 to achieve the purpose of pulling and unlocking, and can be pulled out from the female connector 50 along with the male connector 1.

[0050] In summary, the pull-to-unlock male electrical connector of this invention mainly consists of a metal plate fixed to its insulating body. A limiting ring extends rearward from this metal plate, and a pull strap passes through the limiting ring and engages with the pressing spring on the insulating body via a transverse through-hole. Thus, when the user pulls the strap, the limiting ring converts the rearward pulling force into a downward pulling force on the pressing spring, causing it to move downward and release the original locking state with the female electrical connector's outer shell slot, achieving the purpose of pull-to-unlock. Therefore, the male electrical connector of this invention can be unlocked by hand or by pulling. Furthermore, the metal plate is fixed to the insulating body with three claws, and further, first and second slots are formed on the first and second protrusions on the top surface of the insulating body, making the metal plate more securely mounted on the insulating body and able to withstand repeated pulling without detaching.
