Description

Technical Field

[0001] This utility model relates to the field of spring switches, and in particular to a protective cover for spring switches. Background Technology

[0002] The tumbler switch in a car door lock is the core mechanical component that enables the opening and closing of a car door lock. Its working principle and structure directly affect the reliability and security of the lock. The tumblers, through their unique shape, height, and arrangement, correspond one-to-one with the teeth of a specific key. Each key's teeth push the tumbler to a specific position. Only when all tumblers are correctly pushed to the unlock position can the lock cylinder turn, thus achieving unique verification of "one key, one lock." The complex combination of tumblers greatly increases the difficulty of unauthorized unlocking. An unauthorized key cannot align all the tumblers simultaneously, thus preventing the lock cylinder from turning, effectively preventing technical unlocking and brute-force attacks.

[0003] Before the protective cover for the spring contacts is installed, user feedback statistics show that about 40% of the spring contacts of the micro switch are deformed. After a single spring contact is deformed, the performance will fail, and there is a risk that the car door will not close, the car door will open automatically, or the car door will not open. During the production process, there is a possibility of deformation of the spring contacts, which will affect the pass rate of the micro switch production and the user experience.

[0054] Figures 1 to 10 The diagram shown is a structural schematic of an embodiment of the spring switch protective cover of this utility model.

[0055] Example 1

[0056] The spring switch protective cover includes an injection-molded semi-enclosed protective shell 1 and a spring micro switch 2. One end of the spring micro switch 2 is detachably connected to the injection-molded semi-enclosed protective shell 1, and the other end of the spring micro switch 2 is provided with a locking component 6 to engage with the cover injection-molded shell 3.

[0057] The end of the spring-loaded micro switch 2 located in the inner cavity of the cover injection molded housing 3 is connected to a connecting cable 4, and the inner cavity of the cover injection molded housing 3 is filled with epoxy potting compound to form a potting compound 5.

[0058] The potting compound 5 is an A / B two-component epoxy potting compound.

[0059] In this technical solution, after the injection-molded semi-enclosed protective shell 1 is welded, the injection-molded semi-enclosed protective shell 1 and the cover injection-molded shell 3 are installed to prevent deformation of the spring sheet during glue filling, turnover, and transportation. The positioning post of the injection-molded semi-enclosed protective shell 1 is installed inside the protective cover, and the spring sheet is bent in multiple reverse directions at 5mm intervals from the edge of the protective cover to prevent deformation of the spring sheet. This significantly reduces the number of manual manufacturing processes and touches, and significantly improves the product qualification rate and reduces costs.

[0060] The spring-load micro switch 2 includes a switch end 21 and a spring body 22. One end of the spring body 22 is connected to two engaging tabs 23, which are inclined.

[0061] One end of the spring body 22 is engaged with one end of the switch terminal 21 via a locking piece 23.

[0062] The switch terminal 21 and the injection-molded semi-enclosed protective shell 1 are detachably connected by two front-to-back disassembly bolts 7.

[0063] In this technical solution, the spring-loaded micro switch 2 and the injection-molded semi-enclosed protective shell 1 can be connected using the disassembly bolt 7.

[0064] The spring-loaded micro switch 2 can be installed onto the injection-molded semi-enclosed protective shell 1 using the disassembly bolt 7.

[0065] The locking assembly 6 includes a locking plate 61 and a locking slot 62. Two symmetrically distributed locking plates 61 are connected to one end of the cover injection molded housing 3 near the spring micro switch 2.

[0066] The spring-loaded micro switch 2 has slots 62 on both sides. The card plate 61 and the slots 62 engage. The injection-molded housing 3 and the spring-loaded micro switch 2 are connected by the engagement of the card plate 61 and the slots 62.

[0067] In this technical solution, the snap-fit ​​assembly 6 facilitates the connection between the spring-loaded micro switch 2 and the injection-molded housing 3.

[0068] In use, push the cap injection molded housing 3 and the card plate 61 toward one end of the spring micro switch 2, and then move the card plate 61 into the card slot 62, thereby completing the connection between the spring micro switch 2 and the cap injection molded housing 3.

[0069] The entire production process of the spring-loaded micro switch 2 is as follows: the spring-loaded micro switch 2 is installed into the protective cover so that the protective cover can protect the spring-loaded micro switch 2 and prevent the spring from deforming.

[0070] Then it is loaded into the glue-dispensing fixture and the glue-dispensing process is carried out. After the glue is dispensed, it is baked and cured, and then the heat-shrinking tube process is carried out.

[0071] Then, the injection-molded semi-enclosed protective shell 1 is tested for switch continuity and travel.

[0072] Finally, the finished product is inspected and packaged for storage.

[0073] Example 2

[0074] As an embodiment of this application, the difference between it and Embodiment 1 is that the spring micro switch 2 and the injection-molded semi-enclosed protective shell 1 are connected by an auxiliary component 8. The auxiliary component 8 includes a fixing rack 81 and a fixing plate 82. The fixing rack 81 is connected to both sides of the cover injection-molded shell 3.

[0075] A fixed plate 82 is provided on one side of the injection molded housing 3, and a movable plate 83 is provided on the other side of the injection molded housing 3. One side of the fixed plate 82 is connected to the adjustment component 9, and the bottom of the movable plate 83 is connected to the injection molded semi-enclosed protective shell 1.

[0076] In this technical solution, the auxiliary component 8 can be used to further engage the position of the cap injection molded housing 3, thereby increasing the stability between the spring micro switch 2 and the cap injection molded housing 3.

[0077] Both the fixed plate 82 and the movable plate 83 are connected to auxiliary locking blocks 85 on the side near the injection-molded housing 3, and the auxiliary locking blocks 85 are disposed in the locking slot 62.

[0078] In this technical solution, the auxiliary card block 85 can further increase the stability of the connection between the spring micro switch 2 and the injection molded housing 3.

[0079] The adjustment component 9 includes a support side plate 91. The top of the injection-molded semi-enclosed protective shell 1 is connected to two support side plates 91, and the two support side plates 91 are respectively rotatably connected to the two ends of the rotating screw 92.

[0080] The rotating screw 92 is threadedly connected to a movable frame 93, and one side of the movable frame 93 is connected to one side of the movable plate 83.

[0081] In this technical solution, the position of the movable plate 83 can be adjusted by the adjustment component 9 so as to lock the position of the injection molded housing 3.

[0082] Multiple anti-deviation rails 94 are connected between the two support side plates 91, and the surface of the anti-deviation rails 94 is slidably connected through the movable frame 93.

[0083] In this technical solution, the movement trajectory of the moving frame 93 can be limited by the anti-deviation track 94.

[0084] The rotating screw 92 is connected to a rotating gear 95. Locking tooth plates 96 are respectively engaged on both sides of the rotating gear 95. The locking tooth plates 96 are detachably connected to the top surface of the injection-molded semi-enclosed protective shell 1 by mounting screws 97.

[0085] In this technical solution, the position of the rotating gear 95 can be locked by the locking tooth plate 96, thereby locking the position of the moving frame 93.

[0086] The locking tooth plate 96 has an L-shaped cross-section, and a reinforcing plate 98 is connected to the inner side of the locking tooth plate 96.

[0087] In this technical solution, the stability of the locking tooth plate 96 structure can be increased by using the reinforcing plate 98.

[0088] In use, one end of the injection molded housing 3 is attached to one end of the spring micro switch 2. Then, the rotating gear 95 or other tools or the rotating screw 92 is used to rotate the screw 92. When the screw 92 rotates, it can drive the moving frame 93 to move along the anti-deviation track 94, which can drive the moving plate 83 and the corresponding moving rack 84 to move. At this time, the injection molded housing 3 can be pushed to move, so that the injection molded housing 3 can be locked in the fixed plate 82 and the moving plate 83, so that the fixed rack 81 and the moving rack 84 on both sides are locked together. At this time, the auxiliary locking block 85 moves into the slot 62, thereby completing the connection between the spring micro switch 2 and the injection molded housing 3.

[0089] After the connection is completed, the locking tooth plates 96 on both sides are installed onto the top of the injection-molded semi-enclosed protective shell 1 using the mounting screws 97. At this time, the two locking tooth plates 96 are respectively attached to both sides of the rotating gear 95, so that the rotating gear 95 and the locking tooth plates 96 are engaged and locked, thus locking the position of the rotating gear 95 and the rotating screw 92, thereby locking the position of the cover injection-molded shell 3, and completing the connection between the spring micro switch 2, the cover injection-molded shell 3 and the injection-molded semi-enclosed protective shell 1.

[0090] This method can avoid damage to the slot 62 and scratches on the surface of the spring micro switch 2 when pushing the card plate 61 directly.
