An electrical connection system includes an electrical connector electrically connected to a chip module, and an adapter disposed on one side of the electrical connector. The chip module laterally extends to form a conducting portion. Two rows of terminals are disposed in the adapter, and form a slot therebetween for the conducting portion to be inserted therein. When the conducting portion is not inserted in the slot, the width of the slot is greater than the thickness of the conducting portion, so that a zero insertion force is required for insertion of the chip module. After the chip module is inserted in the slot, under the effect of an external force, the width of the slot is reduced to an extent that the terminals urge against the conducting portion, which ensures close electrical connection between the terminals and the chip module.

A socket for a ball joint having a socket body with an opening and a hollow space, which comprises a concave inside peripheral surface that delimits the hollow space and extends around a longitudinal axis, and which is axially divided into two body halves which merge together in a transition zone, each of which comprises an inside peripheral surface half. A first body half comprises a first inside peripheral surface half which lies on a spherical surface and is closed, in the circumferential direction, and a second body half which comprises the socket opening, at least one slot extending axially and a second inside peripheral surface half which is closed in the circumferential direction, or closed apart from the slot. The second body half is designed such that the second inside peripheral surface half lies outside the spherical surface at least an axial distance away from the transition zone.

The invention relates to a self-focusing laser processing device. A container for containing a non-linear medium is fixed between a lens and a workbench by the aid of a clamping mechanism. A laser beam is focused on the surface of the non-linear medium, the laser beam focused by the lens enters the non-linear medium to be transferred to produce self-focusing, and through two times of focusing by the lens and the non-linear medium, the laser beam leaving the container has the extremely small diameter and is linearly spread to the surface of a workpiece. The depth of the non-linear medium in the container, that is, the self-focusing distance L is related to energy of the laser beam and the refractive index of the adopted non-linear medium. A water jet auxiliary device is also provided, and the laser focus point on the surface of the workpiece coincides with the jet injection point center. Impact of water jet on the surface of the workpiece carries away residues and heat removed by laser. Lens focusing and self-focusing are combined, almost half of the diameter of the laser beam is reduced, and the energy density of the laser beam is increased. Laser alignment transfer is realized after self-focusing, the divergence angle is small, longitudinal etching is facilitated, the processing depth is increased, and the etching accuracy and efficiency are guaranteed.

The present invention relates to a motor stator, in particular, a magnetic pole spaced arrangement combined stator. The magnetic pole spaced arrangement combined stator includes a stator component anda stator insert component; the stator magnetic poles of which the serial numbers are odd numbers, of the stator component and the stator insert component and the stator magnetic poles of which the serial numbers are even numbers, of the stator component and the stator insert component, are arranged alternately; in the winding machining process of a concentrated winding, a large machining operation space is provided between two adjacent stator magnetic poles, and therefore, the slot opening width of stator core wire slots can be reduced under a condition that the winding machining of the concentrated winding is not affected, or closed slots can be adopted as the stator core wire slots, and therefore, a cogging torque can be lowered, a brushless direct-current motor or permanent magnetic synchronous motor can use integer-slot windings, the selection range of the number of slots and the number of poles in the design of the brushless direct-current motor or the permanent magnet synchronous motor can be extended, and the performance of the motor can be improved. The combined stator can realize pole variation and speed variation when applied to an asynchronous motor, so that the asynchronous motor can be facilitated to decrease an additional torque generated by a tooth harmonic magnetic field, and therefore, the efficiency of the motor can be improved.
