Description

Technical Field

[0001] The utility model relates to the technical field of magnetic heads, and particularly relates to a card swiping device, a card reader, a magnetic head and a fixing component. Background Art

[0002] In the magnetic head structure of the prior art, such as the magnetic head disclosed in the patent application document with the application number CN202310301755.4, its structure can be referred to Figure 1 , the magnetic head includes structures such as a housing, a fixing block, and a magnetic sheet group, and is provided with a plurality of elastic pieces. During assembly, the heads of the left and right magnetic sheet groups are clamped and fixed by a snap ring, so as to form a single-track semi-finished component from a single-track winding product, a magnetic sheet group, and a gap sheet. Then, the single-track semi-finished component is sequentially placed into the magnetic sheet group grooves of the fixing blocks fixed in the housing to form three magnetic tracks of the magnetic head. The left and right sides of the single-track semi-finished component are separately clamped and fixed by the elastic pieces placed in the fixing block and are in contact with the housing to achieve grounding conduction. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a fixing component, which can facilitate the fixed installation of the magnetic sheet component in the housing, simplify the structure and assembly process of the magnetic head, and improve the assembly efficiency of the magnetic head.

[0004] The utility model proposes another alternative solution different from the prior art, and the technical solution adopted is as follows: a fixing component for fixedly installing a magnetic sheet component in a housing, including a fixing block and an elastic member. The fixing block is provided with a first placement groove and a second placement groove. The first placement groove is used for placing the magnetic sheet component, and the second placement groove is used for placing the elastic member. The elastic member includes a first elastic piece and a second elastic piece integrally formed. The first elastic piece can abut against the magnetic sheet component, and the second elastic piece can abut against the inner wall of the housing, and the magnetic sheet component is fixedly installed in the housing by relying on the acting force generated during abutment.

[0005] The beneficial effects of the present utility model are as follows: The present fixing component adopts a new type of elastic member, which is provided with a first elastic sheet and a second elastic sheet. During assembly, by using the abutting force between the first elastic sheet and the magnetic sheet assembly and the abutting force between the second elastic sheet and the outer shell, the assembly of the fixing component and the magnetic sheet assembly can be fixedly installed in the outer shell. The structure and assembly process of the magnetic head are simpler, which can improve the assembly efficiency of the magnetic head and reduce costs. The new type of elastic member uses an elastic sheet-like structure to achieve abutting fixation. The first elastic sheet on one elastic member can simultaneously abut against multiple magnetic sheet assemblies. Even for a magnetic head structure with multiple tracks, there is no need to additionally increase the number of first elastic members. Therefore, the number of components of the fixing component and the magnetic head can be reduced, further simplifying the structure and assembly process of the fixing component and the magnetic head, and improving the assembly efficiency of the magnetic head. In addition, the elastic member uses the first elastic sheet and the second elastic sheet to respectively abut against the magnetic sheet assembly and the outer shell. The abutting surface is large and the abutting force is relatively balanced, which can make the structure of the magnetic head more compact and stable, and ensure the electrical performance of the magnetic head.

[0006] For the above-mentioned fixing component, the fixing block is an integral structure, and the elastic member is fixedly installed in the second placement groove.

[0007] For the above-mentioned fixing component, the first elastic sheet has a straight-edge structure, the second elastic sheet has a bent structure, and the second elastic sheet protrudes outward from the outside of the fixing block.

[0008] For the above-mentioned fixing component, the second placement groove includes a first card slot and a relief notch. The first elastic sheet is snapped into the first card slot, and the second elastic sheet protrudes outward from the outside of the fixing block through the relief notch.

[0009] For the above-mentioned fixing component, the first placement groove includes a supporting groove and a receiving groove. The supporting groove is communicated with the first card slot. The supporting groove is used to position and support the end of the magnetic sheet assembly, and the receiving groove is used to receive the remaining part of the magnetic sheet assembly.

[0010] For the above-mentioned fixing component, a "V"-shaped groove is formed in the middle of the fixing block. When the second elastic sheet abuts against the inner wall of the outer shell, the "V"-shaped groove is forced to contract, so that the first elastic sheet abuts against the magnetic sheet assembly.

[0011] The present utility model also discloses a magnetic head, which includes an outer shell, a magnetic sheet assembly and the above-mentioned fixing component. Since this magnetic head adopts the above-mentioned fixing component, it has at least all the beneficial effects that the above-mentioned fixing component can bring.

[0012] For the above-mentioned magnetic head, a welding area is provided at the position where the first elastic sheet abuts against the magnetic sheet assembly.

Detailed Description of the Embodiment

[0025] The following details the embodiments of the present utility model:

[0026] Embodiment 1

[0027] Referring to Figure 2 and Figure 3 , an embodiment of the present utility model provides a fixing component for fixedly installing a magnetic disk component 300 of a magnetic head in a housing 400. The structure of the magnetic disk component 300 can be the same as that in the prior art and is an assembly of structures such as a magnetic disk group 310, a winding product 320, and a gap piece 600. The fixing component includes a fixing block 100 and an elastic member 200. The fixing block 100 is provided with a first placement groove 110 and a second placement groove 120. The first placement groove 110 is used for placing the magnetic disk component 300, and the second placement groove 120 is used for placing the elastic member 200. The elastic member 200 includes a first elastic piece 210 and a second elastic piece 220 formed integrally. Referring to Figures 2 to 5 , when the magnetic disk component 300 is fixedly installed in the housing 400 by using this fixing component, the assembled magnetic disk component 300 is placed in the first placement groove 110, and then the assembly of the fixing component and the magnetic disk component 300 is placed in the housing 400 together. At this time, referring to Figure 6 , the first elastic piece 210 and the second elastic piece 220 on the elastic member 200 can respectively abut against the magnetic disk component 300 and the inner wall of the housing 400, so that the elastic member 200 is compressed and generates a reaction force, thereby using the reaction force generated during abutment to fixedly install the magnetic disk component 300 in the housing 400.

[0028] This fixing component adopts a new type of elastic member 200. The new type of elastic member 200 is provided with a first elastic piece 210 and a second elastic piece 220. During assembly, by using the abutting force between the first elastic piece 210 and the magnetic disk component 300 and the abutting force between the second elastic piece 220 and the housing 400, the assembly of the fixing component and the magnetic disk component 300 can be fixedly installed in the housing 400. The structure and assembly process of the magnetic head are simpler, which can improve the assembly efficiency of the magnetic head and reduce costs. The new type of elastic member 200 uses an elastic sheet-like structure to achieve abutting fixation. The first elastic piece 210 on one elastic member 200 can simultaneously abut against multiple magnetic disk components 300. Even for a magnetic head structure with multiple tracks, there is no need to additionally increase the number of the first elastic members 200. Therefore, the number of components of the fixing component and the magnetic head can be reduced, further simplifying the structure and assembly process of the fixing component and the magnetic head and improving the assembly efficiency of the magnetic head. In addition, the elastic member 200 uses the first elastic piece 210 and the second elastic piece 220 to respectively abut against the magnetic disk component 300 and the housing 400. The abutting surface is large and the abutting force is relatively balanced, which can make the structure of the magnetic head more compact and stable and ensure the electrical performance of the magnetic head.

[0029] It should be noted that this fixing component is applicable to both single-track and multi-track magnetic heads. When applied to a multi-track magnetic head structure, a plurality of first placement grooves 110 are correspondingly provided on the fixing block 100, and a plurality of magnetic sheet components 300 are also correspondingly provided. Each magnetic sheet component 300 is correspondingly placed in a first placement groove 110. As Figure 5 shown, in some embodiments, the magnetic head is a three-track magnetic head, and correspondingly three groups of first placement grooves 110 are provided, and three groups of magnetic sheet components 300 are also provided. The three groups of magnetic sheet components 300 are respectively placed in the three first placement grooves 110. Regardless of the number of first placement grooves 110 and magnetic sheet components 300, there is no need to additionally increase the number of elastic members 200. The first elastic pieces 210 on the elastic members 200 can simultaneously abut against a plurality of magnetic sheet components 300, and one group of elastic members 200 can be used to fixedly install a plurality of magnetic sheet components 300 in the housing 400. It should be noted that one group of elastic members 200 mentioned here can refer to either one elastic member 200 or, as Figure 2 and Figure 3 shown, two elastic members 200 are oppositely arranged, so as to abut against both ends of the magnetic sheet component 300. The statement that there is no need to additionally increase the number of elastic members 200 means increasing on the original number. For example, in some embodiments, an elastic member 200 can be provided only at one end of the magnetic sheet component 300, and for both single-track and multi-track magnetic heads, one elastic member 200 is used. Another example is that in some embodiments, two elastic members 200 can be oppositely arranged at both ends of the magnetic sheet component 300, and for both single-track and multi-track magnetic heads, two elastic members 200 are used.

[0030] Furthermore, the fixing block 100 is of an integral structure, and the elastic member 200 is fixedly installed in the second placement groove 120 by means of encapsulation or interference fit, etc., so that the elastic member 200 and the fixing block 100 can become an integral part. It is difficult for the elastic member 200 to fall off or move from the fixing block 100. Therefore, the elastic member 200 and the fixing block 100 can be supplied as an integral part, thus simplifying the assembly process of the magnetic head. Further, continue to refer to Figure 2 and Figure 3, the first elastic piece 210 has a straight-edge structure, the second elastic piece 220 has a bent structure, and the second elastic piece 220 protrudes outward from the outside of the fixing block 100. Further, the second placement groove 120 includes a first clamping groove 121 and a relief notch 122. The first elastic piece 210 is clamped in the first clamping groove 121, and the second elastic piece 220 protrudes outward from the outside of the fixing block 100 through the relief notch 122. The first elastic piece 210 with a straight-edge structure can be better clamped in the first clamping groove 121, further ensuring that the elastic member 200 will not fall off or move from the fixing block 100. The second elastic piece 220 with a bent structure can protrude outward from the outside of the fixing block 100 through the relief notch 122, so as to better realize the abutment against the inner wall of the housing 400. In addition, the cooperation of the straight-edge structure and the bent structure enables the elastic member 200 to be easily deformed when pressed, and generates a reaction force to fixedly install the magnetic sheet assembly 300 in the housing 400.

[0031] Further, the elastic member 200 can be placed in the molding die of the integrated fixing block 100 by means of die encapsulation, and the elastic member 200 and the fixing block 100 are combined into a whole part by means of injection encapsulation. Further, both the first elastic piece 210 and the second elastic piece 220 are strip-shaped sheet structures. Correspondingly, the first clamping groove 121 is also a long and narrow groove structure. Therefore, the first elastic piece 210 can also be snapped into the first clamping groove 121 by means of interference fit. Whether it is die encapsulation or interference fit, the elastic member 200 can be firmly fixed in the fixing block 100 to form a whole part, and the elastic member 200 is difficult to fall off or move from the fixing block 100. Therefore, the elastic member 200 and the fixing block 100 can be supplied as a whole part, thus simplifying the assembly process of the magnetic head.

[0032] Further, continue to refer to Figure 2 and Figure 3 , the first placement groove 110 includes a supporting groove 111 and a receiving groove 112. The supporting groove 111 communicates with the first clamping groove 121. The supporting groove 111 is used to position and support the end of the magnetic sheet assembly 300, and the receiving groove 112 is used to receive the rest of the magnetic sheet assembly 300. The supporting groove 111 communicates with the clamping groove, so that the first elastic piece 210 in the clamping groove can abut against the magnetic sheet assembly 300 in the supporting groove 111. For one first placement groove 110, there are two opposing supporting grooves 111, which are respectively used to position and support the two ends of the magnetic sheet assembly 300, and the structure of the middle part of the magnetic sheet assembly 300 is received in the receiving groove 112.

[0033] Further, a "V"-shaped groove 130 is formed in the middle of the fixing block 100, and the bottom structure of the "V"-shaped groove 130 is thinner. Refer to Figure 7When the second elastic piece 220 abuts against the inner wall of the housing 400, the elastic member 200 is compressed and will react on the fixed block 100, causing the "V"-shaped groove 130 to undergo a slight deformation under force. The "V"-shaped groove 130 will slightly close up, driving the first elastic piece 210 to press against the magnetic piece assembly 300, effectively transmitting the pressure of the elastic member 200 to the magnetic piece assembly 300, making the first elastic piece 210 fit more closely against the end of the magnetic piece assembly 300. Furthermore, the heads of the left and right magnetic piece groups 310 can be tightly clamped with the spacer 600, locking the contact gap between them, preventing the magnetic head inductance from being abnormal and ensuring the electrical performance of the magnetic head. Further, the middle part of the fixed block 100 is an area for accommodating the magnetic piece assembly 300, and the "V"-shaped groove 130 is formed on the connecting arms on both sides of this area.

[0036] Further, a welding area is provided at the position where the first elastic piece 210 abuts against the magnetic piece assembly 300, and the magnetic piece assembly 300 and the elastic piece can be strengthened and fixed by laser welding in the welding area. Further, when the magnetic head structure is a multi-track magnetic head, there are multiple groups of magnetic piece assemblies 300, and a baffle 500 is provided between each adjacent two groups of magnetic piece assemblies 300.
