Description

Technical Field

[0002] As a convenient connection component, connectors have been widely used in various industries, such as the new energy vehicle industry. Due to different use environments, there will be various requirements for the outlet direction of the connector. In order to improve versatility and reduce investment costs, socket sharing is usually selected. The plug has a variety of outlet angles, so the plug has different structures such as straight and curved. When the 12-core elbow plug and socket are connected and fixed, in order to facilitate the connection between the two, a rotatable power lever is often provided on the plug. By controlling the power lever, the two are tightly connected and not easy to fall off.

[0003] However, when the plug and the socket are locked by a rotatable power lever, the power lever often shakes under the action of the turn pin during use due to the lack of a limiting mechanism, thereby affecting the connection strength of the plug and the socket; the pin column inside the socket and the socket shell are integrally injection-molded, but there is a lack of a reinforcement mechanism between the multiple pin columns, which will cause the pin columns to deform during demolding after injection molding, which not only makes it inconvenient to set the pins, but also causes the plug and the socket to be misaligned when plugged in, affecting use; therefore, the utility model proposes a 12-core elbow plug and socket to solve the above problems.

[0031] In this embodiment, a plurality of pin posts 23 are provided inside the socket shell 21, wherein the socket shell 21 and the plurality of pin posts 23 are integrally injection molded, and slots are provided on the plurality of pin posts 23 for inserting pins, and gaps are provided between the plurality of pin posts 23, wherein reinforcing ribs 24 are provided between every two pin posts 23, and the reinforcing ribs 24 prevent the pin posts 23 from being easily deformed during injection molding and demoulding, and the plug assembly 1 and the socket assembly 2 are not biased when being inserted; see Figure 1 and Figure 2 , is a schematic diagram of the plug assembly 1 and the socket assembly 2 after being plugged in and combined. At this time, the power-assisting rod 12 is in a locked state. Specifically, when the plug assembly 1 and the socket assembly 2 are plugged in, the power-assisting rod 12 is in a vertical state. The front end of the power-assisting rod 12 is pressed to make the rotating groove 124 of the power-assisting rod 12 rotate around the engaging column 22 as the axis, and the power-assisting rod 12 changes from a vertical state to a horizontal state. Then, the front end of the power-assisting rod 12 is pressed to make the engaging hole 125 at the front end engage with the ball 17, and the power-assisting rod 12 is locked. At this time, the plug assembly 1 and the socket assembly 2 are connected and fixed.

[0032] For further information, see Figure 3The locking mechanism includes a limit column 14, a fixing plate 15, a spring 16 and a ball 17. The limit column 14 is arranged at the connection end between the plug housing 11 and the plug 13, the fixing plate 15 is arranged at the connection end between the plug 13 and the plug housing 11, a sliding groove is opened inside the limit column 14, and the spring 16 is arranged inside the sliding groove. One end of the spring 16 is connected to the fixing plate 15, and the other end is connected to the ball 17.

[0033] For further information, see Figure 3 A snap-in hole 125 is provided at the front end of the booster rod 12 , and the snap-in hole 125 is snap-fitted with the ball 17 .

[0034] In this embodiment, refer to Figure 1 and Figure 2 When the power-assisting rod 12 needs to be locked, the power-assisting rod 12 is pressed to change from a vertical state to a horizontal state. At this time, the ball 17 will be squeezed by the front end of the power-assisting rod 12, and the spring 16 carries the ball 17 into the sliding groove inside the limiting column 14. When the power-assisting rod 12 is in a horizontal state, the ball 17 is facing the clamping hole 125 at the front end of the power-assisting rod 12. The spring 16 pushes the ball 17 into the clamping hole 125 under the action of the restoring force, thereby completing the locking of the power-assisting rod 12; the size of the sliding groove inside the limiting column 14 is slightly larger than the maximum outer diameter of the spring 16 and the ball 17.

[0035] For further information, see Figure 4 The booster rod 12 is provided with two relatively spaced connecting plates 121 , and opposite surfaces of the two connecting plates 121 are provided with rotating pins 122 , which are rotatably connected to the plug housing 11 .

At this time, the power-assisting rod 12 is in a locked state. Specifically, when the plug assembly 1 and the socket assembly 2 are plugged in, the power-assisting rod 12 is in a vertical state. The front end of the power-assisting rod 12 is pressed to make the rotating groove 124 of the power-assisting rod 12 rotate around the engaging column 22 as the axis, and the power-assisting rod 12 changes from a vertical state to a horizontal state. Then, the front end of the power-assisting rod 12 is pressed to make the engaging hole 125 at the front end engage with the ball 17, and the power-assisting rod 12 is locked. At this time, the plug assembly 1 and the socket assembly 2 are connected and fixed.
