Detailed Description

The following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1-6.

Example 1: referring to fig. 2, the metal contact cage comprises an open-loop annular body 1, wherein the annular body 1 is provided with a plurality of hollow holes, two ends of the open-loop annular body 1 are respectively a main connecting end 11 and an auxiliary connecting end 12, the middle of the main connecting end 11 is provided with a plurality of convex teeth 14, and the middle of the auxiliary connecting end 12 is provided with tooth holes 13 matched with the convex teeth 14; the convex teeth 14 are inserted into the tooth holes 13, and the convex teeth 14 are connected with the middle part of the auxiliary connecting end 12 through welding; both sides of the main connection end 11 are also connected to both sides of the sub connection end 12 by welding.

Compared with the prior art, the technical scheme has the advantages that the convex teeth 14 and the tooth holes 13 are arranged in the middle of the main connecting end 11 and the middle of the auxiliary connecting end 12, so that the connecting surface between the main connecting end 11 and the auxiliary connecting end 12 is increased; i.e., the area of the weld is increased, thereby avoiding or reducing the chance of a desoldering. Secondly, the cooperation of the convex teeth 14 and the tooth holes 13 also forms a positioning to avoid the falling.

Example 2: see fig. 3-6; the utility model provides a metal contact cage, its includes ring body 1 of open-loop, and ring body 1 is equipped with a plurality of fretwork holes, and 1 both ends of ring body of open-loop are main connection end 11 and auxiliary connection end 12 respectively, and main connection end 11 is equipped with convex master connection piece 15 of a plurality of, at least one side is equipped with main card 16 in the both sides of master connection piece 15, auxiliary connection end 12 is equipped with the main spread groove 18 that is used for the holding connection piece, and the length of main spread groove 18 is greater than the length of main connection piece 15, and at least one side of main spread groove 18 is equipped with a plurality ofly and main card 16 matched with main draw.

When the metal contact cage is sleeved, an open-loop annular body 1 is adopted for convenient sleeving; after the sleeve joint, the two ends of the open ring are connected, and an interval is left between the two ends of the open ring after the sleeve joint; the traditional scheme adopts welding to connect two spaced ends; because the welding position is small, the connecting force is small, and the desoldering is easy to generate when the welding machine is subjected to large internal stress; according to the technical scheme, welding steps are directly reduced, two ends are connected in a clamping mode, in actual application, the length of the main connecting groove 18 is 1.5-2 times that of the main connecting piece 15, and as the auxiliary connecting end 12 is provided with the plurality of main clamping grooves 17, the main clamping piece 16 can be connected with one proper main clamping groove 17 in connection; when a connecting terminal with a larger outer diameter is encountered, the main card 16 can be clamped by selecting a proper main card slot 17 according to the requirement, and the operation is convenient. And the cost is reduced, and the welding steps are reduced.

Further, two main connecting pieces 15 are arranged in the middle of the main connecting end 11, wherein a main clamping piece 16 is arranged on the upper side of one main connecting piece 15, and a main clamping piece 16 is arranged on the lower side of the other main connecting piece 15.

After the primary connection end 11 is connected with the secondary connection end 12, the primary card 16 may be separated from the card slot when the connector is rotated because the primary card 16 is thin; in order to avoid the main cards 16 from separating, the technical scheme adopts the two main connecting pieces 15, and the main cards 16 on the two main connecting pieces 15 are in different lateral directions. So that the two main cards 16 form an interlock when the connector is rotated, thereby preventing simultaneous removal from the main card slot 17.
