Description

Pin type jack connector Technical Field The present utility model relates to circuit devices, and more particularly, to a pin jack connector. Background The pin jack connector is a component part of a jack on medical investigation and monitoring instruments such as a nerve monitor, the female end of the pin jack connector is welded on a PCB (printed circuit board) of the equipment through a contact pin, the other end of the contact pin is inserted into a crown spring of a male end, the crown spring of the male end is connected with a wire rod of the equipment, and signals are transmitted from the female end of the connector through the wire rod connected with the male end. The pin type jack connector needs to meet certain plug force requirements in the use process, and after 1000 times of male-female opposite plug, the plug force still needs to be more than or equal to 6.7N. The existing pin type jack connector only depends on the crown spring at the male end to provide the plugging force, and along with the increase of the frequency of plugging of the connector, the plugging force provided by the crown spring is also gradually weakened, and after the detection of 1000 times of plugging of most pin type jack connectors, the plugging force cannot meet the requirement, so that the service life of the connector is limited. Disclosure of utility model In order to solve the above-mentioned problems, the present utility model provides a pin jack connector, which is characterized by comprising: The female end connector comprises a female end outer die and a female end contact pin, wherein the female end contact pin is arranged in the female end outer die, and a step bulge is arranged on the inner wall of the female end outer die; The male end connector comprises a male end outer die and a male end crown spring, wherein the male end crown spring is arranged in the male end outer die; the male end connector is inserted into the female end outer die, and the female end contact pin is inserted into the crown spring insertion hole of the male end crown spring through the outer die insertion hole of the male end outer die. Further, the pin-type receptacle connector as described above, wherein the female-end connector is provided with a pin groove to which the female-end pin is fixed, and a female-end opening is provided on the other end of the female-end connector opposite to the pin groove, from which the male-end connector is inserted into the female-end outer mold. Further, the pin jack connector as described above, wherein the stepped boss is located adjacent to the pin slot at the end of the female end opening. Further, the pin jack connector as described above, wherein an end face of the male end overmold near an end of the overmolded jack is designed as a bevel. Further, the pin jack connector as described above, wherein an end of the male end crown spring remote from the crown spring jack is connected with a connecting wire, and an end of the connecting wire remote from the male end crown spring protrudes from the male end outer die. According to the utility model, the step bulge is arranged on the inner side wall of the female end outer die, so that the pressure and friction force between the female end outer die and the outer side wall of the male end outer die are increased, and the insertion and extraction force provided by the utility model is still more than 6.7N after 1000 times of opposite insertion of the female end connector and the male end connector, so that the service life of the pin type jack connector is prolonged.
