Detailed Implementation
[0029] To better illustrate the purpose, technical solution, and advantages of this utility model, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0030] like Figures 1 to 3 The diagram shows a plug-in connection assembly for a side-mounted signal channel according to an embodiment of the present invention. The plug-in connection assembly includes a first connector 10 and a second connector 20 that can be plugged into each other.
[0031] The first connector 10 is configured as a male-terminal-female plug structure, comprising an insulating female housing 11 and a pair of conductive male terminals 13. The front end of the insulating female housing 11 is provided with a insertion hole 12, within which a pair of axially parallel conductive male terminals 13 are disposed. The second connector 20 is configured as a female-terminal-male plug structure that mates with the first connector 10, comprising an insulating male housing 21 and a pair of conductive female terminals 23. The front end of the insulating male housing 21 is provided with a insertion post 22, within which a pair of axially parallel conductive female terminals 23 are disposed. Specifically, the first connector 10 and the second connector 20 mate with each other, such that the insertion post 22 of the insulating male housing 21 can be inserted into the insertion hole 12 of the insulating female housing 11, and each conductive male terminal 13 can be correspondingly inserted into the interior of each conductive female terminal 23.
[0032] In this embodiment, the plug-in connection assembly is used for power transmission in a system consisting of a battery, charger, and load. A pair of conductive male terminals 13 of the first connector 10 and a pair of conductive female terminals 23 of the second connector 20 can be used to conduct positive and negative power to the system.
[0033] In this type of plug-in connector assembly, the insulating female housing 11 and the insulating male housing 21 are used for holding during insertion, providing insulation and protection. Generally, the insulating female housing 11 and the insulating male housing 21 are approximately cuboid in shape. The insertion hole 12 is located at the front end of the long side of the cuboid of the insulating female housing 11, and the conductive male terminal 13 extends along the long side of the cuboid. A pair of conductive male terminals 13 are arranged along the wide side of the cuboid.
[0034] In these types of plug-in connector assemblies, the cross-sectional shapes of the plug hole 12 and the plug post 22 are typically configured to be approximately rectangular. The outline dimension of the plug post 22 is smaller than that of the insulating male shell 21 to form a limiting step. Based on the ability to plug and fit and to insulate the conductive female terminal 23, the plug post 22 may be provided with a groove extending along the long side of the cuboid to save material. The outline shape of the plug hole 12 matches that of the plug post 22. In some embodiments, the size of the plug hole 12 may be slightly smaller than that of the plug post 22 to make the connection more secure. Material-saving grooves may also be provided on the inner wall of the plug hole 12.
[0035] In this type of connector assembly, the conductive male terminal 13 is typically cylindrical, and the conductive female terminal 23 is also typically cylindrical with an internal cylindrical hole, allowing the conductive male terminal 13 to be inserted into the conductive female terminal 23. To ensure the stability of the terminal's conductivity, the conductive male terminal 13 has a cross-shaped groove with an outer diameter slightly larger than that of the conductive female terminal 23. This allows the portions of the conductive male terminal 13 divided by the cross-shaped groove to elastically deform towards the center during insertion, applying contact pressure to the inner wall of the hole in the conductive female terminal 23.
[0036] To enable signal channel configuration and compatibility with older connections, in this embodiment, the first connector 10 is further equipped with a first signal terminal 31, and the second connector 20 is further equipped with a second signal terminal 41. The first signal terminal 31 is axially parallel to the conductive male terminal 13, meaning it extends along the long side of the cuboid of the insulating female housing 11, so that the first signal terminal 31 is also connected when the conductive male terminal 13 is plugged in. Similarly, the second signal terminal 41 is axially parallel to the conductive female terminal 23. The first signal terminal 31 is located on the side of the insulating female housing 11 outside the insertion hole 12, allowing the insertion hole 12 of the first connector 10 to be connected to any matching connector without obstructing the connection. The second signal terminal 41 is located on one side of the insertion post 22 of the insulating male housing 21, corresponding to the position of the first signal terminal 31, ultimately ensuring that the first signal terminal 31 and the second signal terminal 41 make conductive contact when the insertion hole 12 of the first connector 10 mates with the insertion post 22 of the second connector 20.
[0037] For example, when the first signal terminal 31 is located on the side of the conductive male terminal 13 near the negative pole of the first connector 10, the corresponding second signal terminal 41 is located on the side of the conductive female terminal 23 near the negative pole of the second connector 20. Thus, when the first connector 10 and the second connector 20 are connected, the first signal terminal 31 also connects with the second signal terminal 41.
[0038] For another example, the first signal terminal 31 extends from the insulating female shell 11 by at least a certain length, and similarly, the second signal terminal 41 also extends from the insulating male shell 21 by at least a certain length, so that when the conductive male terminal 13 is fully inserted into the conductive female terminal 23, the first signal terminal 31 and the second signal terminal 41 also make conductive contact with each other.
[0039] refer to Figure 2 and Figure 3 On the one hand, when the first connector 10 and the second connector 20 are plugged in, the plug-in hole 12 of the insulating female shell 11 will be connected to the plug-in post 22 of the insulating male shell, and a pair of conductive male terminals 13 will be plugged into a pair of conductive female terminals 23. At the same time, the first signal terminal 31 and the second signal terminal 41 will also make conductive contact with each other. Thus, not only can power be transmitted through the conductive male terminal 13 and the conductive female terminal 23, but also signal transmission can be achieved through the first signal terminal 31 and the second signal terminal 41, enabling rich functions such as battery parameter identification and battery control to be extended from the signal. For example, if the first connector 10 is used in a charging device or load, and the second connector 20 is used in a battery, then when the battery equipped with the second connector 20 is plugged in and connected to the charging device or load equipped with the first connector 10, not only power transmission but also signal transmission can be achieved.
[0040] refer to Figure 4 On the other hand, when the first connector 10 is plugged into the older male-female connector 501, the insertion hole 12 of the first connector 10 will be connected to the male structure of the older male-female connector 501, and simultaneously, a pair of conductive male terminals 13 of the first connector 10 will be connected to the female structure of the older male-female connector 501, thus enabling basic power transmission. For example, if the first connector 10 is used in a charging device or load, the older battery can be plugged into the charging device or load equipped with the first connector 10.
[0041] At the same time, refer to Figure 5 When the second connector 20 is plugged into the older female-male connector 502, the pins 22 of the second connector 20 will connect to the female connector structure of the older female-male connector, and simultaneously, a pair of conductive female terminals 23 of the second connector 20 will connect to the female connector structure of the older female-male connector 502, thus enabling basic power transmission. For example, if the second connector 20 is used in a battery, the battery equipped with the second connector 20 can be plugged into an older charging device for charging, and can also be plugged into an older load for power supply.
[0042] Therefore, the plug-in connection component of this utility model not only enables a variety of functions such as battery parameter identification and battery control through the setting of the first signal terminal 31 and the second signal terminal 41, but also avoids the problem of incompatibility with the old connector by setting the signal channel. Overall, the plug-in connection component of this utility model can improve the user experience and increase the efficiency of promoting new functional products.
[0043] In other embodiments of the present invention, the connector may be configured as a cylindrical or other shape according to the application scenario.
[0044] Regarding signal transmission at signal terminals, such as Figure 1 and Figure 2 As shown, in this embodiment, specifically, the front end of the first signal terminal 31 is located between the front contact position and the rear contact position of the conductive male terminal 13 in the insertion direction. In other words, the length of the first signal terminal 31 extending along the long side of the cuboid is less than the length of the conductive male terminal 13 extending along the long side of the cuboid, so that the first signal terminal 31 will not protrude from the front end of the insulating female shell 11, thus avoiding affecting the insertion operation of the first connector 10. Similarly, the front end of the second signal terminal 41 is located between the front contact position and the rear contact position of the conductive female terminal 23 in the insertion direction, which can avoid affecting the insertion operation of the second connector 20. Furthermore, in this embodiment, it is preferred that the first signal terminal 31 is configured as a female terminal and the second signal terminal 41 is configured as a male terminal, so that when the connector is inserted, the second signal terminal 41 will be inserted into the first signal terminal 31. It is understandable that the conductive male terminal 13 and the conductive female terminal 23 have a certain contact distance when they are plugged in, while the extension length of the first signal terminal 31 and the second signal terminal 41 is relatively short. Therefore, while ensuring conductive contact, the contact distance between the first signal terminal 31 and the second signal terminal 41 is also relatively short.
[0045] Regarding the settings of the signal terminals, such as Figure 1 and Figure 2 As shown in this embodiment, specifically, in the first connector 10, two first signal terminals 31 are configured, arranged along the height of the cuboid, thereby reducing the lateral extension distance of the insulating female shell 11 and reducing the space occupied by the first connector 10. Simultaneously, the distance between the axis of the upper first signal terminal 31 and the axis of the conductive male terminal 13 is equal to the distance between the axis of the lower first signal terminal 31 and the axis of the conductive male terminal 13, thereby maximizing the distance between the terminals without increasing the height of the insulating female shell 11 and avoiding contact between the terminals. Similarly, two second signal terminals 41 are also configured, their positions corresponding to the two first signal terminals 31. That is, when the first connector 10 and the second connector 20 are plugged in, the two first signal terminals are respectively plugged into the second signal terminals 41.
[0046] It is worth noting that the two first signal terminals 31 can be used to transmit the positive and negative poles of the signal. In a non-isolated system, the first signal terminal 31 can be configured as one as the positive pole of the signal, while the conductive male terminal 13 of the negative pole is used as the negative pole of the signal.
[0047] As connectors, typically in the first connector 10, the rectangular cross-section of the socket 12 has chamfers on one side of its upper and lower edges, while the other side of its upper edge is not chamfered. This creates an asymmetrical structure between the two opposite sides of the socket 12, preventing reverse connection of the connector. Similarly, in the second connector 20, the rectangular cross-section of the pin 22 also has chamfers on one side of its upper and lower edges, while the other side of its upper edge is not chamfered. This creates an asymmetrical structure between the two opposite sides of the pin 22, preventing reverse connection of the connector.
[0048] Regarding the protection of signal terminals, such as Figure 1 and Figure 2 As shown, the insulating female housing 11 has a secondary insertion hole 32 on the chamfered side of the insertion hole 12, and both first signal terminals 31 are disposed within the secondary insertion hole 32. Correspondingly, the insulating male housing 21 has a secondary insertion post 42 on the chamfered side of the insertion post 22, and both second signal terminals 41 are disposed within the secondary insertion post 42. Thus, to accommodate the chamfer, the cross-sections of the secondary insertion hole 32 and the secondary insertion post 42 are respectively configured in a U-shape, thereby improving insertion stability. For ease of insertion, the front end of the secondary insertion hole 32 is flush with the front end of the insertion hole 12, and the bottom of the secondary insertion hole 32 is further forward than the bottom of the insertion hole 12. Correspondingly, the front end of the secondary insertion post 42 is further backward than the beginning of the insertion post 22, and the root of the secondary insertion post 42 is flush with the root of the insertion post 22.
[0049] The second signal terminal 41, serving as a positive terminal, is configured to protrude from the front end of the sub-pin 42 for insertion into the first signal terminal 31, which serves as a negative terminal. Since it is a signal terminal, the exposed portion of the second signal terminal 41 does not conduct electricity. It is understood that in other embodiments of the present invention, the first signal terminal 31 may be configured as a positive terminal, and the second signal terminal 41 may be configured as a negative terminal. In this embodiment, the front end of the second signal terminal 41 may be disposed within the sub-pin 42.
[0050] Regarding plug-in connection components, such as Figure 2 and Figure 3As shown, in the first connector 10, the rear end of the conductive male terminal 13 extends rearward beyond the insulating female housing 11, thereby being soldered to the electrical conductor. The rear end of the first signal terminal 31 also extends rearward beyond the insulating female housing 11, thereby being soldered to the signal line. Similarly, in the second connector 20, the rear ends of the conductive female terminal 23 and the second signal terminal 41 extend rearward beyond the insulating male housing 21, respectively. In this embodiment, the rear ends of both the conductive male terminal 13 and the first signal terminal 31 extend in a straight line. In other embodiments, the rear ends of the conductive male terminal 13 and the first signal terminal 31 may also extend at a right angle, thereby enabling surface mount soldering of the circuit board.
[0051] The above embodiments mainly describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
