Abstract

A crystal head with a split structure relates to a crystal head. It is to solve the problem that the shrapnel is easy to break or deform during the repeated plugging and unplugging process of the conventional crystal head, which leads to the reduction of the life of the crystal head. The connection part of the utility model has a groove on the side close to the shrapnel, and one end of the shrapnel is inserted into the groove; the bottom of the main body of the crystal head and the upper surface of the shrapnel are provided with protrusions, and the protrusions on the shrapnel are larger than the main body of the crystal head. The protrusions on the top are closer to the connection part, and the two ends of the spring are respectively sleeved on the two protrusions, and when the shrapnel is in a natural state, the spring is in a compressed state. The shrapnel and the connecting part of the crystal head are in a split structure, and when the crystal head is repeatedly plugged and pulled out, the shrapnel will not be broken or deformed, which greatly prolongs the service life of the crystal head. And even if the shrapnel is damaged, the whole crystal head will not be scrapped, just remove the spring and replace the shrapnel.

Description

A crystal head with split structure

technical field

The utility model relates to a crystal head.

Background technique

Commonly used crystal heads, as shown in Figure 3 and Figure 4, include three parts: the main body of the crystal head, the shrapnel and the connecting part. One end of the shrapnel is fixed on the main body of the crystal head through the connecting part, and the shrapnel and the connecting part are an integrated structure. The shrapnel is usually made of plastic material or metal sheet. During the repeated plugging and unplugging process of the crystal head, the root of the plastic shrapnel is easily broken, resulting in damage to the crystal head, and the shrapnel made of metal flakes is prone to deformation, which reduces the service life of the crystal head.

Utility model content

The purpose of the utility model is to solve the problem that the shrapnel is easily broken or deformed during the repeated plugging and unplugging process of the conventional crystal head, which leads to the reduction of the life of the crystal head, and provides a crystal head with a split structure.

A crystal head with a split structure described in the utility model includes a crystal head main body, a shrapnel, a connecting part and a spring,

There is a groove on the side of the connecting part close to the shrapnel, the size of the opening of the groove is larger than the size of the bottom of the groove, and one end of the shrapnel is inserted into the groove;

The bottom of the crystal head body is provided with a first protrusion, and the upper surface of the shrapnel is provided with a second protrusion, and the second protrusion is closer to the connecting part than the first protrusion, and the two ends of the spring are respectively sleeved on the first protrusion and the first protrusion. When the second protrusion is on and the shrapnel is in a natural state, the spring is in a compressed state.

The structure of the crystal head described in the utility model is simple. Compared with the conventional crystal head, the shrapnel and the connecting part have a split structure. life of the head. And even if the shrapnel is damaged, the whole crystal head will not be scrapped, just remove the spring and replace the shrapnel.

detailed description

Specific Embodiment 1: This embodiment is described in conjunction with FIG. 1 . A crystal head with a split structure described in this embodiment includes a crystal head main body 1, a shrapnel 2, a connecting part 3 and a spring 4.

There is a groove on the side of the connecting part 3 close to the shrapnel 2, the size of the opening of the groove is larger than the size of the bottom of the groove, and one end of the shrapnel 2 is inserted into the groove;

The bottom of the crystal head body 1 is provided with a first protrusion 1-1, and the upper surface of the elastic piece 2 is provided with a second protrusion 2-1, and the second protrusion 2-1 is closer to the connection than the first protrusion 1-1. Part 3, both ends of the spring 4 are sleeved on the first protrusion 1-1 and the second protrusion 2-1 respectively, and when the elastic piece 2 is in a natural state, the spring 4 is in a compressed state.

As shown in Figure 1, when the shrapnel 2 is not pressed, the spring 4 is in a compressed state, and because the second protrusion 2-1 is closer to the connecting part 3 than the first protrusion 1-1, the angle a is an obtuse angle, so the spring 4 The force on the shrapnel 2 can be decomposed into two directions: one direction is the pressure to the left to ensure that the shrapnel 2 will not fall off from the groove on the connecting part 3; the other direction is downward pressure to ensure that the shrapnel 2 will not fall off. The clamping part 2-2 can be tightly clamped at the socket of the crystal head, so as to ensure that the crystal head cannot slip out of the socket. The method of use is the same as that of a conventional crystal head, only need to press the tail of the shrapnel 2 to insert the crystal head into the socket. When the tail of the shrapnel 2 is pressed, the spring 4 is further compressed, and since the size of the opening of the groove is larger than the size of the bottom, the other end of the shrapnel 2 can slide slightly in the groove of the connecting part 3 . After the crystal head enters the socket, release the shrapnel 2, and the shrapnel 2 returns to its natural state, and the downward component force of the spring 4 on the shrapnel 2 makes the shrapnel 2 tightly stuck in the socket of the crystal head.

The structure of the crystal head described in this embodiment is very simple. Compared with the conventional crystal head, the shrapnel 2 and the connecting part 3 have a separate structure. When the crystal head is inserted and pulled out repeatedly, the shrapnel 2 will not break or deform. Greatly prolong the life of the crystal head. Moreover, even if the shrapnel 2 is damaged, the entire crystal head will not be scrapped. It is only necessary to disassemble the spring 4 and replace the shrapnel 2.

Embodiment 2: This embodiment is a further limitation of the crystal head with a split structure described in Embodiment 1. In this embodiment, the bottom of the groove on the connecting part 3 extends to the inside of the crystal head body 1 .

Enlarging the depth of the groove can improve the stability of the structure of the crystal head, and the deeper the groove, the harder it is for the shrapnel 2 to fall off. However, the crystal head sockets on communication equipment or electronic equipment are all standard interfaces, and their size is fixed, and the internal space of the socket is very limited. If the opening of the groove is extended to increase the depth of the groove, the size of the crystal head will be too large. Therefore, in this embodiment, the bottom of the groove will be extended inward, which will not increase the size of the crystal head, but can also improve the stability of the crystal head structure.

Embodiment 3: This embodiment is a further limitation of the crystal head with a split structure described in Embodiment 1 or 2. In this embodiment, one end of the shrapnel 2 embedded in the groove has an arc-shaped end surface. During the use of the crystal head, the shrapnel 2 will move relative to the bottom of the groove, and the arc-shaped end surface can reduce friction, so that the end of the shrapnel 2 can slide freely.

Specific Embodiment 4: This embodiment is a further limitation of the crystal head with a split structure described in Embodiment 1 or 2. In this embodiment, the first protrusion 1-1 and the second protrusion 2-1 Limiting structures 5 are arranged on the top.

As shown in FIG. 2 , the limiting structure 5 is used to fix both ends of the spring 4 to improve the structural stability of the crystal head.
