Description

TECHNICAL FIELD

[0001] The utility model relates to connector technical field, concretely is a kind of high-power connector that inner conductor outer diameter and outer conductor inner diameter ratio is 2.2:5. BACKGROUND

[0002] In communication base station, between board and board, between board and filter, need to be connected by connector. Connector includes male head and female head. When connecting, female head shell is inserted into male head shell, and the outer side wall of female head shell is in contact with the inner side wall of male head shell, the end of female head shell abuts against the limiting step of male head shell, to realize installation limiting.

[0003] The above structure will form two paths, one is that the outer side wall of female head shell is connected with the inner side wall of male head outer side, and the other is that the end of female head shell is connected with the limiting step of male head outer side, which will cause the following three defects: 1, easy to cause secondary grounding problem; 2, easy to produce contact jump to cause current not to continue; 3, easy to cause three-order problem.

[0004] Therefore, how to overcome the above defects has become a problem to be solved by the technical personnel in the field. INVENTION CONTENTS

[0005] To solve the technical problems in the background art, the utility model discloses a kind of high-power connectors that inner conductor outer diameter and outer conductor inner diameter ratio is 2.2:5.

[0006] The utility model provides a kind of high-power connector that inner conductor outer diameter and outer conductor inner diameter ratio is 2.2:5, including male head and female head, male head is provided with male head shell, female head is provided with female head shell, female head shell is inserted into male head shell, and the outer end of female head shell is equipped with head with the connecting place of male head shell;

[0007] Head is radially protruding to outer side;

[0008] The radial outer side wall of head is in contact with the inner side wall of male head shell;

[0009] The axial end surface of head is isolated from male head shell.

[0010] The above setting makes that only one contact point exists between female head shell and male head shell, so only one path can be formed, thereby avoiding secondary grounding problem, not causing current not to continue due to contact jump, and not causing three-order problem.

[0011] If the axial end face is suspended to realize isolation from the male head shell, the male head and the female head connection structure will be unstable, and the male head and the female head are easy to move relative to each other under axial pressure, based on this, the further improvement is that the specific structure that the axial end face of the head is isolated from the male head shell is that the male head shell is provided with an annular insulator, and the axial end face is in contact with the insulator.

[0012] The connection between the radial outer side wall and the axial end face is a, the connection between the insulator and the male head shell is b, and the distance between a and b directly affects the stability of the isolation of the axial end face from the male head shell, based on this, the further improvement is that the connection between the radial outer side wall and the axial end face is provided with a round or chamfer. By setting in this way, the distance between a and b is increased, so that the stability of the isolation of the axial end face from the male head shell is higher.

[0013] If the position of the insulator is unstable, the structural stability of the connection between the male head and the female head will also be affected, based on this, the further improvement is that the inner wall of the male head shell is provided with a positioning step towards the outside, and the insulator is clamped with the positioning step.

[0014] The beneficial effects of the utility model are that under the action that the axial end face only contacts with the insulator, there is only one contact point between the female head shell and the male head shell, and only one path can be formed, thereby avoiding the secondary grounding problem, and the contact bounce does not cause the current to be not continuous, and the three-order problem is not caused.
