Service HotlineAs the requirements for the use of electrical appliances in various industries continue to increase, the testing specifications for the performance of various components in electrical appliances are also constantly improving. Riveted contact elements are used in various relays, contactors, small switches, thermostats, etc. in low-voltage electrical appliances. The structure of the riveted contact element generally includes a contact base and a rivet riveted to the contact base. The rivet includes a rivet head and a rivet top, the structure of which is shown in FIG. 1 .
Electrical contact element is a kind of low-voltage electrical products and household electrical products widely used in switches, relays, thermostats, circuit breakers, contactors, controllers, timers, etc. There are mainly three types of electrical contact elements. 1. Riveting parts , riveting the rivet on the copper piece; 2. Welding piece, welding the sheet contact on the copper piece; 3. Stamping piece, punching the composite tape into components. Existing rivet contacts on the market at present are usually all made of precious metals, such as a simple metal matrix such as gold or silver. Its electrical contact performance is limited by a single metal material, and its electrical contact performance is poor; and due to certain requirements for metal purity in production, production efficiency is low, and production costs are high, resulting in the production of products that cannot be sold on a large scale in the market. and application.
When the rivet is riveted, it is often necessary to locate and fix the rivet. However, the common rivet positioning mechanism at present often has no way to effectively and quickly remove the restriction on the rivet after the rivet is fixed, which makes it difficult for the nailing mechanism to be inserted. Quickly drive the positioned rivets.
structure for concealing installation screws, comprising a locking piece, a driving piece, a bottom plate, a blocking cover and a handle head, the lower ends of the two locking pieces are provided with positioning holes, and the locking pieces pass through the positioning holes and the locking piece positioning posts on the base Snap and fix, the middle of the two locking pieces is provided with a protruding point, the movable groove of the driving piece corresponds to the protruding point of the nine locking pieces for fixing, the riveting point holes and screw holes of the bottom plate and the riveting points of the base The position that matches the screw holes and is fixed by screws, the blocking cover is directly inserted into the bottom plate, and the blocking cover is fixed by the rotating drive piece, the handle head is inserted into the base, and the slot of the handle head moves to the locking piece at the locking piece Lock the handle.
In order to solve the problem of poor waterproof performance of the existing rivets, Guangdong Yueluo Hardware Industry Co., Ltd. provides a waterproof rivet. By arranging a figure-eight waterproof part for waterproofing on the lower end surface of the waterproof cap, when the object is riveted, The waterproof cap is subjected to the pulling force of the rivet rod and the supporting force of the object. The pulling force and the supporting force cause the waterproof cap to generate stress, which in turn causes the waterproof part of the waterproof cap to be micro-deformed in the closest contact with the object, so as to achieve a good sealing effect.
