Description

Plug assembly

The present invention relates to a plug assembly, and more particularly to a plug assembly for a connector.

At present, plugs are widely used in various electronic products, and plugs usually need to be mated with interfaces of corresponding connectors to achieve electrical connection with electronic devices. However, different types of connectors have different interface sizes, which results in the same plug not being plugged into different types of connector interfaces.

In view of this, it is necessary to provide a plug assembly that can be plugged into different types of connector interfaces.

The plug assembly is for plugging into a connector interface. The plug assembly includes a body, a first plug electrically connected to the body, and at least one second plug. The at least one second plug is detachably sleeved to the first plug and electrically connected to the body by the first plug.

The plug assembly has a plurality of plugs, and the contact terminals of the plug have different sizes, so that the plug assembly can be applied to connectors of different types of interfaces.

2 is an exploded perspective view of the plug assembly of FIG. 1.

Figure 3 is a cross-sectional view taken along line III-III of Figure 1.

4 is a partial assembled view of the plug assembly of FIG. 2.

Please refer to FIG. 1 and FIG. 2 together, which is a plug assembly 100 according to an embodiment of the present invention. The plug assembly 100 includes a body 10, a first plug 20 connected to the body 10, and a second plug 30 detachably sleeved on the first plug 20. One end of the body 10 is electrically connected to a connecting wire 200 (such as a cable) to electrically connect the plug assembly 100 to other external devices, such as headphones.

The body 10 includes a fixing portion 110 and a connecting portion 120 connected to the fixing portion 110. The fixing portion 110 is substantially cylindrical. The fixing portion 110 is formed with a through hole 112 extending in the radial direction. The through hole 112 is for receiving one end of the connecting wire 200 to fix the fixing portion 110 to the connecting wire 200. A first thread 114 is formed on an outer surface of the fixing portion 110. The connecting portion 120 is formed with a screw hole 122 for accommodating the fixing portion 110 in the radial direction. The diameter of the screw hole 122 is substantially equal to the outer diameter of the fixing portion 110. The inner surface of the fixing portion 110 is formed with a second thread 124 that cooperates with the first thread 114. The fixing portion 110 is engaged with the second thread 124 by the first thread 114 to be screwed into the screw hole 122 of the connecting portion 120. A third thread 126 is further formed on an outer side surface of the connecting portion 120 away from one end of the fixing portion 110.

Referring to FIG. 3 together, the first plug 20 includes a substantially cylindrical base portion 210 and a first contact terminal 220 disposed at one end of the base portion 210. The base portion 210 is recessed in the radial direction to form a receiving portion 212. A fourth thread 214 that cooperates with the third thread 126 is further formed on the inner side of the receiving portion 212. The first plug 20 is coupled to the body 10 by a fourth thread 214 and a third thread 126. The first contact terminal 220 is electrically connected to the base 210 and disposed coaxially with the base 210. The base portion 210 is adjacent to one end of the first contact terminal 220 A fifth thread 216 is further formed on the outer side. The fifth thread 216 is substantially identical to the third thread 126. The base portion 210 extends in the direction of the axis A to further form a receiving hole 218 that communicates with the receiving portion 212.

As shown in FIG. 4, the second plug 30 is sleeved on the first plug 20. The shape and structure of the second plug 30 are similar to those of the first plug 20, except that the size (diameter) of the second contact terminal 310 of the second plug 30 is different from the first contact terminal of the first plug 20. The size of the receiving hole 218 of the second plug 30 in the radial direction is larger than the size of the first contact terminal 220 of the first plug 20, so that the second plug 30 is sleeved by the fifth thread 216 to After the first plug 20 , the first contact terminal 220 of the first plug 20 can be received in the receiving hole 218 of the second plug 30 .

It can be understood that in other embodiments, the number of the plug assemblies 100 is not limited to two, that is, the plug assembly 100 has a plurality of plugs, wherein the contact terminals of the plugs are different in size, and the plurality of plugs are sequentially nested. For example, if the plug assembly 100 further has a third plug (not shown), the third plug is further sleeved on the second plug 30, and the second contact terminal 310 of the second plug 30 is received in the receiving hole thereof. in.

In use, the user can select plugs having contact terminals of different sizes according to the model of the connector interface, so that the plug assembly 100 can be used on connectors having interfaces of different types.

It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
