Description
Technical Field
The utility model relates to a wiring equipment field especially relates to a fastener of power adapter DC plug.
Background
With the rapid development of science and technology, the explosive growth of various electronic products drives the vigorous development of the subsidiary industry, and the functions of the power adapter cannot be replaced as the basis of the electronic products. The power adapter has the advantages that: the volume is small and the weight is light; the power consumption is low, and the efficiency is high; the filtering efficiency is greatly improved, and the capacity and the volume of a filter capacitor are greatly reduced; the voltage stabilizing range is wide. Due to the above advantages, the power adapter is widely used in many fields. Currently, many products employ power adapters for the switching power supplies. Due to the requirements of people on the portability, safety, stability and the like of equipment, the use of a power adapter under a specific working condition also brings new challenges and troubles. And the importance of information security has never been the focus of society, people's demand for information transmission confidentiality is increasing day by day, and the stability of the power has also been had higher requirement in data transmission. Under the operating condition of slight vibration, the DC plug of the power adapter can be loosened, so that the use equipment is interrupted, some important data are lost, and great loss is caused to a user. Therefore, based on the problem that the DC plug of the power adapter may get loose during the use process during the product use, causing great loss to users, it is necessary and urgent to develop a fastening device for the DC plug of the power adapter which is easy to assemble and disassemble and has good tightness.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the above-mentioned prior art, aim at providing a be convenient for load and unload, the fastener of the power adapter DC plug that compactness is good.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
a fastening device for a DC plug of a power adapter comprises a device body, wherein the device body comprises shells arranged on the upper side and the lower side of the DC plug, and the shells are fixedly connected through screws; the shell is internally provided with a plug channel matched with the DC plug, and two ends of the shell on the same side with the plug socket are provided with outwards extending convex parts; the insertion ends of the convex parts are provided with circular convex columns; the middle of the convex column is provided with an extrusion gap.
Further, the interval of the extrusion gap is 0.8 mm.
Furthermore, the inner diameter of the socket of the inserting channel is 5.5-9 mm.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a structure size is suitable, does not influence the depth of insertion of DC plug, does not influence electrical property, ensures that this fastener only plays the fixed effect of enhancement, does not have any change to equipment mainboard and electrical property, has really realized convenient dismantlement, strengthens fixed effect.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1, a fastening device for a DC plug of a power adapter comprises a device body, wherein the device body comprises shells 1 arranged at the upper side and the lower side of a DC plug 6, and the shells 1 are fixedly connected with each other through screws 5; a plug channel 3 matched with the DC plug 6 is arranged in the shell 1, and two ends of the shell 1 on the same side with the plug socket are provided with outwards extending convex parts 4; the insertion ends of the convex parts 4 are provided with circular convex columns 2; the middle of the convex column 2 is provided with an extrusion gap 7; the distance between the extrusion gaps 7 is 0.8 mm; the inner diameter of the socket of the inserting channel 3 is 5.5-9mm, and the diameter of the inserting channel is 5.5mm in the embodiment.
As shown in fig. 2, the utility model discloses set up the inserted way according to the structure of DC plug, with the spacing compaction that carries on around the DC plug, with the screw-up shell, guarantee that two lamella shells closely cooperate with the plug, then with the DC plug that installs insert correspond in the equipment can. The convex part on the shell on the same side as the plug socket increases the contact area of the plug and the equipment, and limits the freedom degree of the plug, thereby effectively preventing the plug from moving due to the action of external force and ensuring the stable connection of the plug and the equipment. In order to ensure that the plug is more stably connected with the equipment, the circular convex column of the convex part of the shell can be arranged at the connecting end of the equipment, a mounting hole with a proper distance is formed, the convex column can be inserted into the mounting hole to realize fastening, and the operation is simple and rapid. And the middle of the convex column is provided with an extrusion gap, and the extrusion gap is closed after the convex column is extruded, so that the convex column is easy to insert into the mounting hole. The convex column in the mounting hole can be clamped in the mounting hole due to the extrusion gap, so that the convex column is prevented from being separated from the mounting hole due to equipment vibration.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
