Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the field of electrical connection technology, and more particularly, to a connector assembly and a socket connector. Background Art

[0002] A common connection method in the connector system is the plug-and-socket connection. Usually, the plug (e.g., electrical pin) of the plug connector is inserted into the slot of the socket connector and is brought into contact with the electrical connection terminal in the slot to achieve signal transmission and / or power transmission between the electrical component connected to the plug connector (e.g., a circuit on a printed circuit board) and the electrical component connected to the socket connector (e.g., an electrical cable). This plug-and-socket connection method not only needs to consider the connection stability between the plug of the plug connector and the slot (and electrical connection terminal) of the socket connector, but also needs to consider the actual situation that the two need to be repeatedly plugged in and out.

[0034] Specifically, according to an exemplary embodiment of the present disclosure, Figure 2 As shown, the printed circuit board 200 is mounted with a first electrical pin 210 and a second electrical pin 220 for electrical connection. Figure 2 and Figure 3As shown, the socket connector 100 includes an insulating housing 101, and the insulating housing 101 is formed with a first slot 110 and a second slot 120. According to the present disclosure, the insulating housing 101 and the locking member 300 are made of an insulating material such as plastic, and the electrical pins 210 and 220 are made of a conductive material such as copper metal. The first electrical pin 210 is removably inserted into the first slot 110, and the second electrical pin 220 is removably inserted into the second slot 120. The insulating housing 101 is also formed with a locking cavity 130, and the locking cavity 130 is connected to the first slot 110. The locking member 300 is movably disposed in the locking cavity 130 and can move between a first position and a second position. Specifically, the locking member 300 is configured such that: when in the first position (such as Figure 3 110 , and the electrical connection terminals 110 and 120 of the socket connector 100 are connected to each other. When the electrical connection terminals 110 and 120 are connected to each other, the electrical connection terminals 110 and 120 of the socket connector 100 are connected to each other. When the electrical connection terminals 110 and 120 are connected to each other, the electrical connection terminals 110 and 120 of the socket connector 100 are connected to each other. When the electrical connection terminals 110 and 120 are connected to each other, the electrical connection terminals 110 and 120 of the socket connector 100 are connected to each other. When the electrical connection terminals 110 and 120 are connected to each other, the electrical connection terminals 110 and 120 of the socket connector 100 are connected to each other. When the electrical connection terminals 110 and 120 are connected to each other, the electrical connection terminals 110 and 120 of the socket connector 100 are connected to each other. Figure 3 102) shown in the figure, thereby ensuring the connection stability between the electrical pins and the cables through the socket connector. In this way, compared with the related art that requires a locking action to be taken on each electrical pin 210, according to the connector assembly provided by the present disclosure, only one electrical pin 210 among two or more electrical pins 210 and 220 needs to be locked to ensure the connection stability between all electrical pins and the corresponding cables, so it has a simplified structure, convenient operation, cost saving, and meets the installation requirements of a smaller width space. It should be noted that although only one second electrical pin 220 and a corresponding second slot 120 are shown in the illustrated embodiment, other numbers of second electrical pins 220 and corresponding numbers of second slots 120 may also be provided according to actual design requirements.

[0035] According to an exemplary embodiment of the present disclosure, Figure 2 and Figure 3 as well as Figure 6As shown, specifically, the first electrical pin 210 has a first mounting end 211 and a first free end 212. The first mounting end 211 is connected to the electrical path of the printed circuit board 220, and the first free end 212 is formed with a lock fitting portion 2120. Figure 3 As shown in FIG. 1 , the locking portion 2120 of the first electrical pin 210 extends out of the first slot 110 and enters the locking cavity 130. More specifically, as shown in FIG. Figure 3 as well as Figure 6 As shown, in the first electrical pin 210, the lock fitting portion 2120 presents a mushroom shape having a cover portion 2121 and a handle portion 2122, wherein the handle portion 2122 extends from the first free end 212, and the cover portion 2121 extends from the handle portion 2122. According to the design concept of the present disclosure, when the first electrical pin 210 on the printed circuit board 200 is inserted and fitted into the first slot 110 of the socket connector 100, the handle portion 2122 of the lock fitting portion 2120 enters into the lock cavity 130 via the first slot 110. At this time, when the locking member 300 is in the first position, the locking member 300 clamps the handle-shaped portion 2122 entering the locking cavity 130 to achieve the locking of the first electrical pin 210 by the locking member 300, and when the locking member 300 is in the second position, the locking member 300 releases the clamping of the handle-shaped portion 2122 entering the locking cavity 130 to release the locking of the first electrical pin 210 by the locking member 300.
