Description

Technical Field

[0001] This utility model relates to the field of loudspeakers, and in particular to a loudspeaker terminal crimping device. Background Technology

[0002] For small-diameter loudspeakers, consumers need a soldering iron to solder the terminals, but many consumers do not have a soldering iron at home, making installation inconvenient.

[0003] Patent document CN217985300U discloses an improved terminal structure for a small loudspeaker, including a main body and two connectors located on the main body. The main body is made of insulating material, and the connectors are made of conductive material. The main body and connectors are directly injection molded and fixed, or the connectors are fixed to the main body with glue. The bottom of the connector has an integrally formed connecting portion, and the connecting portion and the connector are inclined relative to each other. The left and right sides of the connecting portion are integrally formed with upwardly bent portions, and the bent portions and the connecting portion form connecting grooves. Compared with traditional wiring terminals, this utility model can fix the wires without a soldering iron. The improved terminal structure for small loudspeakers facilitates consumer installation and improves consumer satisfaction.

[0004] In the above solutions, the wiring terminal does not specify how to connect to the speaker frame or how to securely connect it to the frame to facilitate wiring. Therefore, it is necessary to provide a speaker wiring terminal crimping device to address the shortcomings of the prior art. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0037] Example 1:

[0038] In this embodiment, as Figure 1-6 As shown, the present invention proposes a speaker terminal crimping device, including a workbench 1, a base plate 2 mounted on the workbench, a fixed frame 3 bolted to the rear end of the base plate, a positioning fixture 4 bolted to the front end of the base plate, a support plate 5 bolted to the top of the fixed frame, a lifting cylinder 6 mounted on the top surface of the front end of the support plate, the output end of the lifting cylinder passing through the support plate and facing the positioning fixture, a crimping assembly 7 provided at the output end of the lifting cylinder, a positioning block 44 provided on the top of the positioning fixture, an installation tube 84 provided in the middle of the terminal block 8, the installation tube being cylindrical with a square cross-section, terminal seats 91 symmetrically provided at both ends of the frame 9, a pair of terminal seats, the installation tube being sleeved on the positioning block, the terminal seat being sleeved on the installation tube, and the crimping assembly crimping the installation tube onto the terminal seat.

[0039] In this embodiment, the positioning fixture is further configured to include a pad 41, an H-shaped fixing block 42, a locking bolt 43, and a positioning block 44. The bottom of the pad is fixed to the base plate, and a pair of pads are symmetrically arranged. The pads can reduce the vibration generated by the pressing. The two ends of the H-shaped fixing block abut against a pad respectively. The locking bolt passes through the H-shaped fixing block and is bolted to the base plate. The bottom of the positioning block is fixed to the H-shaped fixing block, and the top of the positioning block is provided with a protrusion 441.

[0040] In this embodiment, the pressing assembly is further configured to include a conical cylinder 71, a pressing rod 72, and an adjusting bolt 73. The top of the conical cylinder is connected to the output end of the lifting cylinder, and the bottom of the conical cylinder is provided with multiple bolt holes. The pressing rod is installed at the bottom of the conical cylinder. The adjusting bolt passes through the bolt holes and is connected to the conical cylinder. The adjusting bolt can adjust the height of the pressing rod.

[0041] In this embodiment, the positioning block and the pressing rod are further configured to correspond to each other and have the same axis. When the pressing rod descends, it abuts against the top of the positioning block to complete the pressing work.

[0042] In this embodiment, the wiring terminal is further configured to include a main body 81, a first connector 82, a second connector 83, and a mounting tube 84. The main body is made of insulating material, and a first mounting hole is provided in the middle of the main body. Second mounting holes are symmetrically provided at both ends of the main body. The first connector passes through the second mounting hole on one side and is connected to the main body. The second connector passes through the second mounting hole on the other side and is connected to the main body. The mounting tube passes through the first mounting hole and is connected to the main body.

[0043] Example 2:

[0044] In this embodiment, as Figure 1 As shown, guide rods 10 are provided on both sides of the middle part of the base plate. The bottom of the guide rod is connected to the base plate, and the top of the guide rod extends vertically upward and passes through the support plate. The guide rod is a threaded rod with a fixing bolt at the top. The bottom surface of the fixing bolt abuts against the support plate to lock the guide rod. The guide rod can strengthen the support function and prevent the support plate from shaking.

[0045] In this embodiment, the workbench is further configured with a pneumatic foot switch at the bottom, which controls the lifting cylinder to move up and down. The pneumatic foot switch is not shown in the figure, and this technology is prior art.

[0046] The working principle of this speaker terminal crimping device is as follows: the operator places the mounting tube of the terminal onto the protrusion on the top of the positioning block, then places the terminal block on the frame onto the mounting tube, presses down the pneumatic foot switch, and the output end of the lifting cylinder descends, causing the crimping rod to descend, so that the bottom of the crimping rod abuts against the protrusion on the top of the positioning block. At this time, the mounting tube is crushed by pressure. Since the mounting tube is cylindrical, the four sides of the mounting tube fit outwards and fit against the terminal block to complete the crimping, thereby fixing the terminal onto the terminal block of the frame.
