Abstract: A water resistant connector jointing with a housing, comprises a base, a sleeve plug disposed in the base, a clamping member disposed in the base and a locking member. The sleeve plug contacts with the neck portion of the base. The locking member is locked at the housing and contacts with the clamping member. The transmission line passes through the locking member, the clamping member, and the sleeve plug such that one portion of the transmission line is exposed at the exterior of the base. The locking member moves linearly and extrudes the clamping member and the sleeve plug such that the sleeve plug has deformation by the extrusion from the neck portion of the base. The effects of water resistance and seal may be achieved by using the sleeve plug to tightly joint with the internal wall of the base and the transmission line.

Abstract: The electromagnetic stimulation device contains at least a positive electrode and at least a negative electrode. An insulating gap having width of a first distance is maintained between the positive and negative electrodes. The positive and negative electrodes are at least at a second distance away from a nerve to be stimulated. A preset voltage is applied to the positive and negative electrodes so that a low-power, low-temperature, high-frequency electromagnetic field covering and stimulating the nerve is produced between the positive and negative electrodes. By the stimulation of the low-power, low-temperature, high-frequency electromagnetic field, the nerve's threshold is increased, the nerve's transmission capability is reduced, and therefore the nerve pain is effectively eased.

Abstract: The desensitizing device contains an electrical stimulation member optionally configured on a support member. The electrical stimulation member contains a control circuit, at least two electrodes, and an electricity supply element. The electricity supply element provides electricity to the control circuit, and the control circuit generates a stimulating current to the electrodes. By configuring a male genital with the support member so that the electrodes are in contact with the penis skin, the stimulating current produced by the control circuit is conducted to the electrodes and provides a low-strength subcutaneous nerve stimulation through the penis skin. The subcutaneous nerve is as such temporarily numbed and desensitized.
