DETAILED DESCRIPTION

[0027] The following is a detailed description of the present invention with reference to the accompanying drawings. Figures 1 to 8 shown.

[0028] Example: See Figures 1 to 4 as well as Figure 6 、 Figure 7 ; A spring terminal installation jig for a charger housing, comprising: a base block 6, a workbench 5 is provided above the base block 6, an elastic guide mechanism is provided between the workbench 5 and the base block 6, and the workbench 5 can move up and down relative to the base block 6; a pad 14 is provided in the middle of the workbench 5, a boss 19 is provided in the middle of the pad 14 for sleeved with the charger housing 4, a through-hole 16 is provided in the middle of the boss 19 for matching with the pin 13, and a countersunk hole 15 is provided at the upper end of the through-hole 16 for overlapping the spring terminal 20; the base block 6 is connected to a rivet column 9, the upper end of the rivet column 9 extends into the through-hole 16, and a gap 18 is left between the rivet column 9 and the upper end surface of the boss 19.

[0029] When the present technical solution is in operation, the mounting portion 21 of the spring terminal 20 is first placed in the countersunk hole 15, and then the charger housing 4 is placed on the boss 19 and sleeved with the boss 19; the pin 13 of the charger housing 4 passes through the mounting hole on the mounting portion 21 and extends into the through-hole 16. Preferably, at this time, the lower end of the pin 13 abuts against or is adjacent to the upper end surface of the rivet column 9, such as a distance of about 1mm between the two. Then, the charger housing is driven downward under external force, and the charger housing 4 drives the boss 19 and the workbench 5 toward the base block 6, causing the elastic guide mechanism to undergo elastic deformation; the lower end of the pin 13 abuts against and squeezes the rivet column 9, causing the lower end of the pin 13 to deform and become thickened; the lower end of the pin 13 is riveted to the mounting portion 21 of the spring terminal 20. The overall structure is simple and easy to operate.

[0030] Secondly, the external force can be provided by a small cylinder, a micro-punch; it can also be provided by a scissor-type clamp, or manpower.

[0031] Furthermore, the installation fixture for the spring terminal 20 also includes a cover 3 for abutting against the upper end of the charger housing 4 , and a pressure block 2 is connected to the upper end of the cover 3 .

[0032] Since the pin 13 of the charger housing 4 is riveted, the upper end of the pin 13 protrudes from the upper end surface of the charger housing 4, which is not conducive to operating the charger housing 4. In order to facilitate the operation of the charger housing 4, the present technical solution provides a cover 3, which covers the outside of the pin 13 and abuts against the upper end of the charger housing 4. At the same time, a pressure block 2 is provided at the upper end of the cover 3, which can directly act on the pressure block 2 when driving the charger housing 4 to move downward; generally speaking, it is only necessary to manually press the pressure block 2, and with the help of the body weight, it is sufficient to drive the charger housing 4 to move downward, and the lower end of the pin 13 is thickened and riveted to the spring terminal 20.

[0033] Furthermore, the elastic guide mechanism includes a mounting hole arranged on the upper end surface of the base block 6, the mounting hole is connected to the guide column 1, the workbench 5 is provided with a vertical guide groove matching the guide column 1, the guide column 1 is inserted into the vertical guide groove, and an elastic member for lifting the workbench 5 upward is provided between the base block 6 and the workbench 5.

[0034] The elastic guide mechanism includes an elastic mechanism and a guide mechanism. The guide mechanism is realized by setting a vertical guide groove and a guide column 1. Specifically, a plurality of mounting holes, such as 4, are set on the base block 6; the guide column 1 is connected to the mounting hole, and the guide column 1 and the mounting hole can be connected by interference fit or matching; the workbench 5 is provided with a vertical guide groove that matches the guide column 1; secondly, in order to provide linearity for the up and down movement of the workbench 5, a linear bearing can be set in the vertical guide groove, and the guide column 1 is sleeved with the executive bearing. The elastic mechanism is mainly achieved by setting an elastic member, and the upper and lower ends of the elastic member are respectively in contact with the workbench 5 and the base block 6. The elastic member is used to reset the workbench 5. After the pin 13 is riveted to the spring terminal 20, the external force is removed, and the workbench 5 is reset with the assistance of the elastic member.

[0035] Furthermore, the elastic member is a spring 11, the upper end surface of the base block 6 is provided with an upper accommodating hole for accommodating the lower end of the spring 11, and the lower end of the workbench 5 is provided with a lower accommodating hole for accommodating the upper end of the spring 11. The two ends of the spring 11 are respectively located in the upper accommodating hole and the lower accommodating hole, and the two ends of the spring 11 are respectively in contact with the workbench 5 and the base block 6.

[0036] Using a spring 11 as the elastic member is cost-effective and practical. Furthermore, providing an upper receiving hole in the base block 6 and a lower receiving hole in the workbench 5 prevents the elastic member from shifting during operation, ensuring that the spring 11 remains vertical. Preferably, the lower receiving hole or both the upper receiving hole and the spring 11 are provided with a column, with the end of the spring 11 sheathed outside the column. The column further secures the spring 11, ensuring that its deformation direction is fixed.

[0037] Furthermore, the workbench 5 is provided with a through hole 7, the upper end of the through hole 7 is provided with a countersunk hole 15, a bolt 8 is provided in the countersunk hole 15, and the base block 6 is provided with a threaded hole matching the bolt 8, one end of the bolt 8 passes through the through hole 7 and is threadedly connected to the base block 6.

[0038] After the bolt 8 is set, the distance that the workbench 5 moves upward is limited, which can prevent the workbench 5 from separating from the guide column 1. In the specific setting, the depth of the countersunk hole 15 is relatively large. During the working process, it is best not to expose the head of the bolt 8.

[0039] See also Figures 5 to 8 A bottom plate 12 is provided under the base block 6, and the base block 6 is fixedly connected to the bottom plate 12; a limit head is provided at the lower end of the guide column 1, and a receiving hole is provided at the lower end of the base block 6 to match the limit head, and the upper end of the guide column 1 passes through the base block 6 and is inserted into the vertical guide groove of the workbench 5.

[0040] Preferably, the lower end of the riveting column 9 is provided with a T-shaped head, and the base block 6 is provided with a mounting hole that matches the T-shaped head.

[0041] In a specific implementation, for example, the guide column 1 can be a long bolt, the head of which is limited in the receiving hole. When the workbench 5 moves up and down relatively, the long bolt is fixed and does not move up and down with the workbench 5.

[0042] Secondly, the T-shaped head of the riveted column 9 increases the force-bearing area between the riveted column 9 and the bottom plate 12, reduces the unit force, and avoids damaging the bottom plate 12. It also facilitates installation.

[0043] Furthermore, a slot 17 for fixing the elastic terminal is provided on the side surface of the boss 19 .

[0044] When the elastic terminal is fixed, the provision of the clamping slot 17 is helpful in assisting in fixing the elastic terminal.

[0045] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
