Embodiment one

In PCB (Printed Circuit Board) plate manufacturing process or after the completion, need to carry out megger test, Whether the insulation performance to judge pcb board is qualified.

Referring to Fig.1-2, the utility model embodiment provides a kind of PCB megger tests component, including：100 He of pedestal Test probe 200；Fixed hole is offered on pedestal 100, fixed hole has arrival end 110 and outlet end 120, fixed hole The bottom of axis and pedestal 100 form angle；The head of test probe 200 sequentially passes through 110 He of arrival end of fixed hole Outlet end, the pcb board for contact measured examination；Outlet end 120 is provided with the fixing piece for fixed test probe 200.

Pedestal 100 is that test probe 200 provides support so that the head (pop one's head in 210) of test probe 200 can stablize The pcb board of contact measured examination.Specifically, it is provided with fixed hole on pedestal 100, the axis of the through-hole is obliquely installed, and is passed through Pedestal 100.When test probe 200 head pass through the fixed hole, and test probe 200 probe 210 can contact just Pcb board to be tested, fixing piece are fixed on fixed hole by probe 200 is tested so that test probe 200 will not be with respect to pedestal 100 move, and test probe 200 realizes the steady contact with PCB plates to be tested, and autonomous resistance test may be implemented.

In test, the bottom surface of pedestal 100 is contacted with pcb board face to be tested, and fixed hole axis tilts, and refers to fixing The axis of through-hole is at a certain angle with respect to shape between the bottom surface or pcb board of pedestal 100, and such structure ensure that pedestal 100 Certain support is provided for test probe 200 so that test probe 200 can be stable at pcb board contact, while test probe 200 head will not vertically be contacted with pcb board, protection probe 210.

In use, pedestal 100 is positioned on pcb board to be detected, the probe 210 for testing probe 200 is led to from fixed The arrival end 110 in hole is stretched into and is stretched out by outlet end 120, the pcb board for making 210 contact measured of probe of test probe 200 try, and is adjusted Whole fixing piece is fixed 200 position of probe is tested, and realizes the test of test probe 200.

As can be seen that PCB megger tests component provided by the utility model is in testing, it is only necessary to by pedestal 100 It is placed in position to be tested, test probe 200 carries out resistance test under the fixation of pedestal 100 to pcb board to be tested, can not Tester's manual manipulation is needed, the both hands of tester have been liberated, tester can carry out data record during measurement Or other work, effectively increase time availability and working efficiency.

It should be noted that fixed hole is oblique to run through pedestal 100, and the outlet end 120 of fixed hole is not pedestal 100 Bottom, when testing probe 200 outlet end being stretched out again, test probe 200 head distance pcb board also have it is certain away from From.It tests probe 200 and continues PCB plates close to until its head contact pcb board, operation fixing piece are fixed probe 200 is tested.

Wherein, the structure of fixing piece can be illustrated below there are many embodiment：

Mode one

Fixing piece in the present embodiment includes fixed ring 130, and fixed ring 130 is fixed on the outlet end 120 of fixed hole；Gu The inside and the outer diameter of test probe 200 for determining ring 130 match, and flexible anti-skid structure is arranged in the inside of fixed ring 130.

In specific implementation, probe 200 is tested for convenience and passes through fixed hole, the aperture of fixed hole is slightly larger than survey Sound out the outer diameter of needle 200.And the internal diameter of fixed ring 130 and the outer diameter of test probe 200 match, flexible anti-skid structure side internal diameter Then it is slightly less than the internal diameter of test probe 200.Tester's test probe 200 that can exert a force passes through the fixed ring 130, flexible Anti-skid structure does not interfere with passing through for test probe 200；When test probe 200 no longer stress, due to soft on the inside of fixed ring 130 Property anti-skid structure presence, test probe 200 outer diameter and fixed ring 130 between frictional force by test probe 200 be fixed on Determine ring 130, through-hole will not be relatively fixed and move by carrying out test probe 200, realize the fixation for testing probe 200.

Flexible anti-skid structure herein can be rubber or silica gel material.

Mode two

Fixing piece in the present embodiment includes the first clamping part and the second clamping part, and the first clamping part and the second clamping part are logical Rotation axis connection is crossed, to form the movable holding chamber for clamping test probe 200；Elastic reset is equipped in rotation axis Part, so that there is the trend of obvolvent, rotation axis to be fixed on pedestal 100 for the first clamping part, the second clamping part.When test probe 200 Across fixed hole and the head contact pcb board of test probe 200, the first clamping part and the second clamping part are opened so that first Clamping part and the second clamping part are tightly clamped probe 200 is tested, and are tested probe 200 with fixed, are realized to testing probe 200 Fixation.

First clamping part and the second clamping part are hinged by rotation axis, to form mobilizable holding chamber.Specifically, first It is provided with the first axle sleeve being rotatably assorted with rotation axis on clamping part, is correspondingly arranged on the second clamping part and matches with rotation axis rotation The second axle sleeve closed, rotation axis sequentially pass through the first axle sleeve and the second axle sleeve and connect the first clamping part and the rotation of the second clamping part It connects.

First axle sleeve and the second axle sleeve correspond to, and rotation axis sequentially passes through the first axle sleeve and the second axle sleeve, the first clamping part energy Axis rotation is enough relatively rotated by the first axle sleeve, the second clamping part can relatively rotate axis rotation by the second axle sleeve, to real Existing first clamping part ensure that the adjustable of holding chamber size relative to the rotation of the second clamping part.

Further, the inner wall of the first clamping part and the second clamping part being provided with non-slip mat, side enhances clamping effect, Second protection test probe 200.

It should be noted that dynamic clamping head and quiet clamping head herein is torsional spring.Torsional spring is a kind of machinery storage power structure, and torque spring is logical It crosses the soft, distortion of the larger elastic material of toughness or rotation to material and carries out storage power, using lever far from release, make it have Mechanical energy.In the utility model embodiment, two torsional spring arms of torsional spring act on the first clamping part and the second clamping part, can Driving force is provided to the obvolvent of the first clamping part and the second clamping part, so that the clamping that the first clamping part and the second clamping part are formed Chamber is tightly gripped probe 200 is tested.

Torsional spring slides in order to prevent, and finite place piece is arranged in the both sides of torsional spring, and the is steadily driven to limit torsional spring One clamping part and the second clamping part obvolvent.

In the utility model at least one embodiment, pedestal 100 is cuboid, and the arrival end 110 of fixed hole is located at length The top surface of cube, the outlet end 120 of fixed hole are located at the side of cuboid.
