The invention discloses a structure for installing and fixing an arc insulation hood, comprising an arc insulation hood (20) and a support (10), wherein the support (10) is provided with a spherical salient point (11), the arc insulation hood (20) is provided with a key way (21) correspondingly matched with the spherical salient point (11), and the key way (21) is in clearance fit with the spherical salient point (11). Due to the designs of the spherical salient point (11) of the support and the key way (21) of the arc insulation hood, the installation is convenient and rapid, a better installation effect is realized on the basis of reducing the quantity of parts like spring pieces, the product reliability is greatly enhanced, and in addition, the product assembly efficiency can be increased.
Description
technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an arc shield installation and fixing structure. Background technique [0002] The existing cooperating installation of the arc shield of the relay and the bracket adopts the fixed installation by relying on the elastic deformation of the spring piece. Usually, the structural design of the product is as follows: figure 1 As shown, the arc shield is in close contact with the product substrate and the outer cover under the action of the elastic force generated by the elastic deformation of the spring leaf, thereby realizing the installation and fixation of the arc shield. [0003] In the relay assembly process, in order to realize the pre-pressure of the spring piece on the arc shield, the spring piece is generally positioned at a certain position on the bracket by using a welding fixture, and welded together, through the deformation of the spring piece itself and the...
