[0002] A relay is an electrical control device that can make a predetermined step change in the controlled quantity in the electrical output circuit according to the change of the input quantity (such as current, voltage, temperature, etc.). When the input quantity reaches the specified value, the output part of the relay will be activated to realize the on-off control of the circuit. The working principle of the relay is based on the electromagnetic effect, and it is usually composed of an iron core, a coil, an armature, a contact spring, etc. When a certain voltage is applied to both ends of the coil, the current flowing through the coil generates a magnetic field. The armature is attracted to the iron core under the action of the electromagnetic force, driving the contacts to close or open, thereby realizing the on-off control of the circuit. The film sleeve used for relay packaging is a structure used to package the relay.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-5 As shown, a film sleeve box for relay packaging comprises a film sleeve box body 1 and a film sleeve box cover 2 arranged at the upper end position of the film sleeve box body 1; an extrusion connection spring 7 is arranged at the middle position of the film sleeve box cover 2, a movable connection plate 13 is arranged at the bottom position of the extrusion connection spring 7, and an airbag extrusion layer 4 is arranged at the side position of the movable connection plate 13. The airbag extrusion layer 4 is made of rubber material, and the inner position of the airbag extrusion layer 4 is filled with air. The movable connection plate 13 can squeeze the extrusion connection spring 7 after being squeezed, and at the same time, its extrusion connection spring 7 will correspondingly apply a reverse force to squeeze the objects on the side of the airbag extrusion layer 4. By squeezing the objects on the side of the airbag extrusion layer 4 by the extrusion connection spring 7, the objects can be stably restricted and effectively prevented from shaking. At the same time, the inside of the airbag extrusion layer 4 can be inflated to increase its expansion degree. By squeezing the connection spring 7 and the inflatable airbag extrusion layer 4, the film sleeve box for relay packaging can be suitable for stable installation and placement of different relays.

[0025] like Figure 1 and Figure 2 As shown, a plug-in installation groove 3 is provided near the corner of the membrane sleeve box body 1, and the plug-in installation groove 3 is a cylindrical groove structure. A PVC plug-in column 5 is provided at the corner of the membrane sleeve box cover 2, and the PVC plug-in column 5 is made of PVC material. The PVC plug-in column 5 is installed and connected with the membrane sleeve box cover 2 by adhesive. An outer rubber sleeve film 6 is provided at the outer position of the PVC plug-in column 5, and the outer rubber sleeve film 6 is connected to the PVC plug-in column 5 by a sleeve knot. The outer diameter of the outer rubber sleeve film 6 is equal to the inner diameter of the plug-in installation groove 3. The membrane sleeve box cover 2 can be plugged into the plug-in installation groove 3 through the PVC plug-in column 5 and its outer rubber sleeve film 6 to be connected to the membrane sleeve box body 1. The outer rubber sleeve film 6 can increase its plug-in friction, thereby making the connection more stable.

[0026] like Figure 1 and Figure 2 As shown, the structure of the film sleeve box body 1 and the film sleeve box cover 2 is composed of a structure of an internal foam layer 8 and an external film 9. The external film 9 is connected to the side of the internal foam layer 8 by bonding. The external film 9 can protect the internal foam layer 8 and reduce the occurrence of the internal foam layer 8 breaking due to its brittleness.

[0027] like Figure 5 As shown, a hygroscopic base plate 10 is provided at the bottom position of the membrane sleeve box body 1, and the outer diameter of the hygroscopic base plate 10 is equal to the inner diameter of the membrane sleeve box body 1. The hygroscopic base plate 10 is connected to the bottom position of the inner side of the membrane sleeve box body 1 by plugging. Silica gel particles 11 are provided at the middle position of the hygroscopic base plate 10, and a breathable filter plate 12 is provided at the upper side position of the hygroscopic base plate 10. The breathable filter plate 12 is made of PVC material. The gap of the breathable filter plate 12 is smaller than the size of the silica gel particles 11. The breathable filter plate 12 is connected to the hygroscopic base plate 10 by snapping. When there is moisture inside the membrane sleeve box body 1, it is easy to enter the relay and cause damage to the internal components of the relay. The silica gel particles 11 inside the hygroscopic base plate 10 can absorb moisture. Because moisture is relatively heavy, the small holes in the breathable filter plate 12 can be more conducive to playing a receiving role and it can facilitate moisture to pass through and be absorbed by the silica gel particles 11, thereby effectively reducing the damage of moisture to the relay.
