Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a combined socket structure. Background Art

[0002] The socket usually has a socket provided with a slot that matches the plug pin, and the plug pin contacts the socket to establish a circuit connection. When the plug is inserted into the socket, the two clamping arms must be squeezed apart to deform the elastic arm and clamp the pin between the two clamping arms to ensure that the plug will not fall out of the socket without external force.

[0003] When the plug is inserted, the contact area between the pin and the two clamping arms is large, which can easily cause jamming. A large force is required to insert the plug, which can easily damage the socket structure and make the elastic arm ineffective. In order to enhance the strength of the socket, the height and thickness of the socket are usually increased, but this will increase the overall size of the product and increase the manufacturing cost.

[0004] Therefore, the utility model provides a combined socket structure to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A combined socket structure includes an elastic curved arm, a first clamping arm and a second clamping arm connected at both ends of the elastic curved arm, a slot is formed between the first clamping arm and the second clamping arm, one side of the first clamping arm and the second clamping arm is a plane, and the other side is an inclined surface, the elastic curved arm is arranged in a U-shape, one side is a plane, flush with the plane side of the first clamping arm and the second clamping arm, and the other side is an inclined surface with a high middle part and low ends, and the two ends of the inclined surface are respectively flush with the higher ends of the inclined surfaces of the first clamping arm and the second clamping arm.

[0007] In a further solution, a first guide block is disposed on the inclined surface side of the first clamping arm, and a second guide block is disposed on the inclined surface side of the second clamping arm.

[0008] A further solution is that the surface of the elastic curved arm is provided with reinforcing ribs.

[0009] A further solution: the other end of the second clamping arm is connected to the wire pressing piece.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The elastic curved arm generating the clamping force is designed as one side of the insertion edge, with the height of the bending part being relatively high and then gradually decreasing in height to transition to the first guide block and the end of the second clamping arm, thereby reducing the height of the first clamping arm and the second clamping arm. The elastic curved arm can generate a larger clamping force without increasing the height of the product, thereby extending the service life of the sleeve and saving manufacturing costs.

[0012] 2. The insertion edge of the socket forms an angle with the end face of the pin, so that the pin contacts a little when inserted into the socket. As the insertion depth increases, the contact area gradually increases. When plugging in the plug, it is comfortable and not stuck, and no excessive force is required, which gives users a good experience and extends the service life of the socket.

[0020] See also Figure 1 , Figure 2In an embodiment of the utility model, a combined plug-in structure includes an elastic curved arm 3, a first clamping arm 1 and a second clamping arm 2 connected to both ends of the elastic curved arm 3, and a slot is formed between the first clamping arm 1 and the second clamping arm 2. One side of the first clamping arm 1 and the second clamping arm 2 is a plane, and the side opposite to the plane is an inclined surface. The inclined surface side of the first clamping arm 1 is provided with a first guide block 11, and the inclined surface side of the second clamping arm 2 is provided with a second guide block 21. The first guide block 11 and the second guide block 21 are arranged oppositely. The elastic curved arm 3 is arranged in a U-shape, with one side being a plane flush with the plane side of the first clamping arm 1 and the second clamping arm 2, and the other side being an inclined surface with a high middle part and low ends. The two ends of the inclined surface are flush with the higher ends of the inclined surfaces of the first clamping arm 1 and the second clamping arm 2, respectively, and the other end of the second clamping arm is connected to the wire pressing piece 5. The inclined side of the socket is the plug insertion side, and the socket insertion side is set to be a relatively high height of the bending part of the elastic curved arm 3, and then gradually lowers the height to transition to the ends of the first clamping arm 1 and the second clamping arm 2, thereby reducing the height of the first clamping arm 1 and the second clamping arm 2. The elastic curved arm 3 can generate a larger clamping force without increasing the height of the product. At the same time, a reinforcing rib 4 can also be provided on the surface of the elastic curved arm 3 to make the clamping force better.

[0021] See also Figure 3 When the plug is inserted into the socket, the pin 6 is guided into the slot by the first guide block 11 and the second guide block 21 which are arranged opposite to each other. At this time, the end face of the pin 6 and the insertion edge form an angle α, and one corner of the pin 6 first contacts the higher end of the elastic curved arm 3, that is, it contacts a point first, and the contact area gradually increases as the insertion depth increases, so that the plug is comfortable and not stuck when plugging in, and no excessive force is required, which gives the user a good experience, avoids violent damage to the socket, and prolongs the service life of the socket. The utility model has a simple and reliable structure and can be stamped and formed. After the socket is unfolded, the material strip is in a strip shape, with a high molding utilization rate, which is convenient for industrial batch manufacturing.
