The utility model provides a dead problem of card is blocked with busbar 7 to ordinary locating clip. The positioning clamp and the bus bar 7 have a certain gap, which can satisfy the micro displacement of the straight line section. When curve bend, busbar 7 receives unstable irregularity, and the direction is changeable complicated, and the strong impulsive force effect of swing in the twinkling of an eye, under the condition that frictional resistance increases by a wide margin in the twinkling of an eye, receive upwards when busbar 7, downwards, left, right, during the strong impact in the twinkling of an eye of five preceding directions, all can realize through the anti-stagnation function of novel locating clip that there is not the jamming between busbar 7 and the novel locating clip to guarantee busbar 7 at the normal technical state who hangs the point.

The utility model discloses the locating clip is that embedded circular or the solid steel ball of columnar order 6 replaces original plane stress point in recess 3 of locating clip, and by two to five steel balls 6 a set ofly, six groups altogether distribute and respectively a set of in the upper left portion of locating clip recess 3, and recess 3 left lower part is a set of, and recess 3 left side is a set of, and novel locating clip recess 3's upper right portion, left lower part, right side are respectively a set of, position and left side symmetry. The solid steel ball 6 is positioned in the positioning clamp groove 3 by the ball clamping block 4, the steel ball 6 can rotate at a fixed position, the salient point of the steel ball 6 protrudes 2-3mm from the fixed part plane of the ball clamping block 4, and the steel ball 6 in the positioning clamp groove 3 plays a role in positioning the busbar 7. When the steel ball 6 and the bus bar 7 in the novel positioning clamp are subjected to the instant impact force conducted by the vehicle, the steel ball and the bus bar form a non-stagnation sliding rolling state in five forward directions, namely upward, downward, leftward and rightward directions, and can still naturally reset when the instant impact force conducted by the vehicle disappears. The technical standard of the positioning clamp is as follows: maximum horizontal workload of 2.5KN, destruction load of 7.5 KN/maximum vertical workload of 3.0KN, destruction load of 9.0 KN.

The utility model discloses adopt the arc salient point of ball type or cylinder type metal ball etc. to play atress and positioning action to busbar 7 among the positioning clamp recess 3. The stress points are evenly distributed on four stress surfaces of the novel positioning clamp groove 3, namely an upper stress surface, a lower stress surface, a left stress surface and a right stress surface, and the stress points are symmetrical in position. Two to five steel balls 6 are in a group, and six groups are formed, and the steel balls 6 play a role in positioning the busbar 7. The stress strength of the stress point is positioned, the stress area between the positioning clamp and the busbar 7 is increased by adopting spherical or cylindrical metal balls and the number of each group of steel balls 6, and the problem that the surface of the busbar 7 is possibly damaged due to the difference between the hardness of the busbar 7 of each manufacturer is solved by increasing the stress area of the steel balls 6. The invention is suitable for connecting and mounting the suspension pin insulator of the rigid contact network and the busbar 7, and can prevent the clamping stagnation of the busbar 7 at a suspension point.
