Definitions

  • the present invention relates to a power outlet for household and similar use, and more particularly to a power socket insert having a maximum permanent clamping force.
  • the structure is not reasonable.
  • the shape of the socket is mostly a simple " ⁇ " slot with a tight neck.
  • the plug is often inserted into the power socket. First, the contact between the socket and the pin is in line contact, and the contact area is very small.
  • the flow-carrying capacity is small; the second is that the sleeve clamping pin is only mechanically elastically clamped by the insert sleeve alone, the clamping force is small, and the contact is not firm; the third is that the plug is inserted into the power socket for a long time, and the mechanical socket is inserted into the power socket.
  • the elasticity is reduced by kilograms until it is lost, and it is prone to poor contact. Due to the small contact area, small clamping force and easy loss of clamping force after long-term use, the contact resistance is large, the contact part is very easy to generate heat, and the heat in turn causes the mechanical elastic acceleration of the insert sleeve to be reduced and lost, which further increases the contact resistance. Large, forming a vicious circle, the probability of danger is great.
  • some power socket inner inserts are made of alloys to reduce contact resistance; some increase the thickness of the copper sleeve in the power socket to increase the clamping force, but they do not completely increase the contact area.
  • the clamping force of the insert sleeve increases the production cost.
  • Some power socket inner insert sleeves are matched with the positive and negative tolerances of the sleeve and the pin to increase the clamping force. When the plug is used, the clamping force of the insert sleeve is large, and the plug and pin are positively and negatively inserted after the plug is inserted multiple times. The tolerance fit is lost, and the insert sleeve eventually loses the clamping force; some power sockets increase the clamping force of the insert by adding external springs or shrapnel, but the process is complicated and costly. Disclosure of invention
  • the invention provides a power socket insert having a maximum contact area when mated with a pin, and having a strong and permanent permanent clamping force, which solves the contact between the insert and the pin when the sleeve is fitted.
  • the small area, small clamping force and easy loss of the problem greatly improve the safety and low cost.
  • the power socket socket of the present invention is characterized in that: it is a slotted power socket insert formed by bending a long elastic metal piece, one of which The upper end of the groove wall is bent toward the bottom wall of the groove to extend a resilient contact piece.

  • the length of the inclined support arm is slightly larger than the square root of the sum of the length of the support arm and the length of the auxiliary support piece.
  • the angle between the auxiliary support piece and the support arm is greater than 90°.
  • the beneficial effects of the invention are: in the process of fitting the pin and the socket, the pin first pushes the elastic contact piece to rotate, and then drives the support arm to the horizontal position through the elastic support piece, gradually becomes a support beam, and is supported on the groove wall. In between, form a "permanent support arm.”

  • Permanent clamping force Since the above-mentioned triangular bracket is gradually formed with the insertion of the bolt, the clamping force is also gradually increased to the maximum with the insertion of the bolt, and is never reduced and lost, and meets and exceeds the Chinese national standard. Due to the formation of the above-mentioned triangular bracket, the clamping force of the insert sleeve is overcome over the serious dependence on the thickness and elasticity of the metal sheet, so the cost is low.
