Attached Figure Description

[0010] Figure 1 This is a perspective view of one state of this utility model.

[0011] Figure 2 This is a perspective view of another aspect of this utility model. Detailed Implementation

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0013] like Figure 1 , Figure 2 As shown, this utility model provides a tooling for welding relays and terminals, including a base 1, on which a relay seat 2 and a terminal seat 3 are provided. The relay seat 2 is provided with at least one relay slot 5 for positioning a relay 4. The side wall of the relay slot 5 near the terminal seat 3 is provided with at least one set of pin slots 7 for placing pins 6 on the relay 4. The terminal seat 3 is provided with at least one set of terminal slots 9 for positioning terminals 8. A pressure frame 10 is provided above the base 1 for pressing the upper side of the relay 4 and the terminal 8. One end of the pressure frame 10 is rotatably connected to the base 1, and the other end of the pressure frame 10 is detachably connected to the base 1 through a locking member 11.

[0014] In use, the terminal 8 is positioned in the terminal slot 9, and the relay 2 is positioned in the relay slot 5. The pin 6 on the relay 4 is placed in the pin slot 7, with the end of the pin 6 resting on the terminal 8 (this is the welding position). Then, the pressure frame 10 is pressed onto the relay 4 and the terminal 8, and one end of the pressure frame 10 is fixed to the base 1 by the locking member 11. This ensures that the welding position between the pin 6 of the relay 4 and the terminal 8 does not change during welding, making welding convenient. After welding, the pressure frame 10 can be opened to remove the relay 4 and the terminal 8, making operation convenient.

[0015] Preferably, a positioning post 17 is provided on the side wall of the relay slot 5. One end of the positioning post 17 can extend into the relay slot 5, and a first elastic element, preferably a spring, is provided between the other end of the positioning post 17 and the relay base 2. When the relay 4 is placed in the relay slot 5, one side of the relay 4 is pressed against the side wall of the relay slot 5, and the positioning post 17 on the other side wall of the relay slot 5 abuts against the other side of the relay 4 under the action of the first elastic element. Specifically, the positioning post 17 is provided on one pair of adjacent side walls of the relay slot 5, which makes the position of the relay 4 in the relay slot 5 certain and accurate.

[0016] Preferably, the outer side of the terminal slot 5 is provided with a fixed baffle 12 that blocks one side of the terminal 8, and the inner side of the terminal slot 5 is provided with a movable baffle 18 that blocks the other side of the terminal 8. A second elastic element, preferably a spring, is provided between the movable baffle 18 and the terminal seat 3. When the terminal 8 is placed into the terminal slot 5, one end of the terminal 8 abuts against the fixed baffle 12, and the movable baffle 18 abuts against the other end of the terminal 8 under the action of the second elastic element. This ensures that the position of the terminal 8 in the terminal slot 5 is determined and accurately positioned.

[0017] Preferably, each side of the base 1 is provided with a mounting seat 13. One end of the pressure frame 10 is rotatably connected to one of the mounting seats 13 via a rotating shaft 14. The other end of the pressure frame 10 is provided with a locking hole 15. The locking member 11 is movably mounted on the other mounting seat 13. One end of the locking member 11 can extend into the locking hole 15, and the other end of the locking member 11 passes through the mounting seat 13 and is provided with an operating handle 16. A third elastic element, preferably a spring, is provided between the locking member 11 and the mounting seat 13. By pulling the operating handle 16, the locking member 11 is disengaged from the locking hole 15. By releasing the operating handle 16, the locking member 11 can extend into the locking hole 15 under the action of the third elastic element, realizing a detachable connection between the pressure frame 10 and the base 1, which is convenient to operate.

[0018] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
