Description

Technical Field

[0001] This utility model relates to the field of terminal feeding trays, and in particular to a terminal feeding tray structure that can prevent terminal deformation. Background Technology

[0002] Beryllium bronze is a typical precipitation-hardening copper alloy. These alloys exhibit good cold-working properties in their soft state after solution treatment, enabling the formation of complex shapes. Subsequent aging heat treatment at appropriate temperatures leads to intense precipitation hardening. Due to their excellent overall properties—high yield strength, elasticity, hardness, wear resistance, and fatigue resistance—they also retain the excellent thermal conductivity, electrical conductivity, corrosion resistance, cold resistance, non-ferromagnetism, and spark generation by the IBU upon impact. Therefore, these alloys are widely used in connector contacts for terminals with complex structures and high elasticity and ductility, such as bullet-shaped terminals, pin-shaped terminals, and crown spring terminals. These terminals are generally formed using a cold-working continuous stamping process. In order to maintain good plasticity during processing, a soft beryllium bronze alloy is selected. However, the mechanical properties of the soft state are poor. After processing and forming, an aging heat treatment is required to cause precipitation hardening of the material, reduce the internal stress after processing, stabilize the shape and size, and at the same time achieve the highest level of strength, hardness and conductivity to meet the mechanical and electrical performance requirements of the terminal.

[0003] Heat treatment production relies heavily on tooling and fixtures, but various types of heating furnace fixtures, trays, frames, and racks must be heated along with the workpieces. In the connector industry, terminals are packaged and handled as a continuous strip wound around a tray. To maintain stability during transportation and prevent loosening and displacement that could cause scratches or deformation, the wrapping is typically quite tight. However, the inner ring of the tray is usually fixed. During aging heat treatment, terminals deform due to thermal expansion and contraction. The tightly wound strip lacks room to stretch, causing the terminals to be squeezed and twisted, resulting in significant residual deformation stress and potentially permanent deformation. Therefore, it is necessary to improve the existing tray design. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a terminal tray structure that can prevent terminal deformation. It can effectively solve the problem that terminals do not have room to expand during heat treatment, resulting in mutual compression and twisting between terminals, leaving a large amount of residual deformation internal stress, which leads to permanent deformation of the terminals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A terminal tray structure for preventing terminal deformation includes an impeller, a first hub, an inner ring member, and a latch. The first hub is coaxially disposed on one side of the impeller. The inner ring member is disposed on the impeller and located on the periphery of the first hub. The inner ring member has a slot, and the outer side of the inner ring member and the impeller together form an accommodating space. The latch is mounted on the first hub and can enter or leave the slot.

[0007] As a preferred embodiment, the impeller has a plurality of first screw holes and the first hub has a plurality of second screw holes, each second screw hole being directly opposite and connected to the corresponding first screw hole.

[0008] As a preferred embodiment, the device further includes a second hub, which is coaxially disposed on the other side of the blade disk.

[0009] As a preferred embodiment, the second hub is provided with a plurality of third screw holes, each of which is directly connected to the corresponding second screw hole.

[0010] As a preferred embodiment, the first hub is provided with a latch groove for receiving the latch, the latch groove is connected to the empty groove, and the aforementioned latch is installed in the latch groove.

[0011] As a preferred embodiment, the latch groove is provided with a shaft hole, and the latch has a rotating shaft, which is installed in the shaft hole, so that the latch can be movably installed in the latch groove of the first hub.

[0012] As a preferred embodiment, the inner ring component includes a first inner ring body and a second inner ring body, and there are two slots, one slot being formed by one end of the first inner ring body and one end of the second inner ring body, and the other slot being formed by the other end of the first inner ring body and the other end of the second inner ring body. Correspondingly, there are two latches.

[0013] As a preferred embodiment, both the first inner ring body and the second inner ring body are crescent-shaped.

[0014] As a preferred embodiment, the impeller is provided with heat dissipation holes, which are multiple holes arranged circumferentially at intervals.

[0015] As a preferred embodiment, the impeller has multiple support holes on its periphery, which are arranged circumferentially at intervals.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By setting the inner ring component on the impeller and located on the periphery of the first hub, the inner ring component has a slot. It can be installed on the first hub by entering or leaving the slot with the latch. During material collection, the latch extends into the slot. After material collection is completed, the latch leaves the slot. When the terminal is heat treated, the existence of the slot can provide a space for the slight deformation caused by thermal expansion and contraction of the terminal, effectively preventing the terminals from squeezing and twisting each other, avoiding the residual deformation internal stress of the terminals, and effectively preventing the terminals from squeezing each other and causing permanent deformation.

[0034] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an impeller 10, a first hub 20, an inner ring 30, and a latch 40.

[0035] The impeller 10 has multiple first screw holes 11 and multiple heat dissipation holes 12 arranged circumferentially; the periphery of the impeller 10 has multiple support holes 13 arranged circumferentially.

[0036] The first hub 20 is coaxially disposed on one side of the blade disk 10; in this embodiment, the first hub 20 is provided with a plurality of second screw holes 21, each second screw hole 21 being directly connected to the corresponding first screw hole 11; the first hub 20 is provided with a latch groove 22 for receiving the latch 40, the latch groove 22 being connected to the empty groove 31, and a shaft hole 23 being provided in the latch groove 22.

[0037] The inner ring component 30 is disposed on the impeller 10 and located on the periphery of the first hub 20. The inner ring component 30 has a slot 301, and the outer side of the inner ring component 30 and the impeller 10 together form an accommodating space 302. In this embodiment, the inner ring component 30 includes a first inner ring body 31 and a second inner ring body 32. There are two slots 301, one of which is formed by one end of the first inner ring body 31 and one end of the second inner ring body 32, and the other slot 302 is formed by the other end of the first inner ring body 31 and the other end of the second inner ring body 32. Both the first inner ring body 31 and the second inner ring body 32 are crescent-shaped.

[0038] The latch 40 is mounted on the first hub 20 in a way that allows it to enter or exit the slot 301. In this embodiment, the latch 40 is mounted in the latch slot 22 and has a pivot 41. The pivot 41 of the latch 40 is mounted in the shaft hole 23, so that the latch 40 is movably mounted in the latch slot 22 of the first hub 20. There are two latches 40.

[0039] Furthermore, it includes a second hub 50, which is coaxially disposed on the other side of the impeller 10. The second hub 50 has a plurality of third screw holes 51, each of which is directly connected to the corresponding second screw hole 21. Specifically, the first hub 20 and the second hub 50 are fixed on the impeller 10 by screws.

[0040] The usage method of this embodiment is described in detail below:

[0041] When receiving materials, both latches 40 are inserted into the corresponding empty slots 301. After receiving the materials, both latches 40 are removed from the empty slots 301 and stored in the corresponding latch slots 22. Then, the two material tray structures are stacked and fixed together using the support column 60. The support column 60 is inserted into the support hole 13. The number of stacked material tray structures can be adjusted according to actual production needs. It can be five, eight or even more.

[0042] The key design feature of this invention is that the inner ring component is set on the impeller and located on the periphery of the first hub. The inner ring component has a slot, and with the help of a latch, it can be installed on the first hub by entering or leaving the slot. During material collection, the latch extends into the slot. After material collection is completed, the latch leaves the slot. When the terminal is heat-treated, the presence of the slot provides a space for the slight deformation caused by thermal expansion and contraction of the terminal, effectively preventing the terminals from squeezing and twisting each other, avoiding the accumulation of a large amount of deformation internal stress in the terminals, and effectively preventing the terminals from squeezing each other and causing permanent deformation.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
