Description

The utility model relates to a terminal crimping tool, in particular to a terminal positioning device of the terminal crimping tool.

Commonly used terminal pliers 10 shown in Figure 1, when in use, the operator must first place one end of a terminal 14 on the jaws 12 of the terminal pliers 10, and pass a stripped insulation wire on it. The electric wire 16 of 15, its other end then protrudes outside the side of this terminal pliers 10, because its area of the occlusal end face of each clip tooth 12 is extremely small, and terminal 14 has no place to butt on it again, so this It is really difficult to place the terminal 14 stably on it, so when using the terminal pliers 10, the operator must not only hold the terminal pliers 10 tightly, but also support the terminals 14 and the electric wires 16 so that they do not The terminal 14 is shifted or the electric wire 16 slips out, etc., but in this way, how to realize stably holding the three items with only two hands so as to facilitate clamping often makes the user feel very troubled.

The main purpose of this utility model is to provide a terminal positioning device that can be installed on one side of a terminal crimping tool in any dismountable manner, so that one end of the terminal that is placed on the clamping part of the terminal crimping tool can be placed against it. rests on it, and sits smoothly on the tooth for crimping.

In order to achieve the aforementioned purpose, the utility model mainly includes a plurality of first fixing parts arranged outside the side of the terminal crimping tool, a plurality of second fixing parts that can be combined with the first fixing parts, and a The accommodating portion at the upper end of each of the second fixing portions has an open end. When combined, each of the open ends corresponds to the outer end of each of the clamping teeth, so that each of the clamping teeth can be placed on the receiving portion. One end of the terminal can be inserted into the accommodating part, and abut against the inner wall of the accommodating chamber, so as to achieve a stabilizing effect without being supported by hands.

Hereby give a preferred embodiment of a utility model, and cooperate with accompanying drawing to do further detailed description as follows, wherein:

Fig. 8 is a combined sectional view (2) of the preferred embodiment (3) of the present utility model.

Please refer to Fig. 2 and 3 at first, the terminal positioning device 21 of the present utility model comprises a screw rod 22 fixed on the side of a terminal clamp 20, a seat body 30 fixed on the screw rod 22, three can be respectively inserted in The positioning piece 40 on the base body 30 and a stop piece 50 fixed between the terminal clamp 20 and the base body 30 .

The seat body 30 is in the shape of a rectangular plate with three notches 32, three screw holes 34 and a first through hole 36. Each of the notches 32 is integrally formed on the inner side of the seat body 30. On, its upper end passes through the upper end face of this seat body 30 respectively, and its lower end then extends downwards a predetermined length on the inner side of this seat body 30 respectively; position, and through the inner and outer sides of the seat body 30; the first through hole 36 is located at the lower end of each screw hole 34, and runs through the inner and outer sides of the seat body 30; The screw rod 22 outside the side of the terminal clamp 20 is fixed with a nut 38 .

Each of the positioning pieces 40 is in an inverted L shape, and has an accommodating portion 42 and a fixing portion 44 respectively. There is a push-out surface 471; each of the fixing parts 44 extends vertically downwards from the outer edge of the opening end 46 of the receiving part 42 to a predetermined length and width, so that it can be inserted into the corresponding seat body 30. In each of the notches 32, tighten the tail end of a screw 45 that is respectively screwed in each of the screw holes 34.

The stop piece (50) is provided with a perforation 52 corresponding to the screw rod 22, and is clamped between the side of the terminal clamp 20 and the seat body 30, and its upper end is also provided with a hole corresponding to each of the clamping teeth. The elongated slot 52 of the surface 26.

When combined, each of the notches 32 on the seat body 30 corresponds to each of the clamping teeth 24 of the terminal clamp 20, and each of the positioning piece receiving parts 42 inserted therein can be positioned at the inner edge of the bottom end. It is tangent to the occlusal surface 26 of each of the clamping teeth 24, so that each of the terminals 28 placed flat on each of the clamping teeth 24 can be inserted through the clamping end 281 protruding from the side of the terminal pliers 20. Each of the accommodating portions 42 is used to prevent the terminal 28 from shifting on the corresponding teeth occlusal surface 26, and at the same time, the clamping end 281 of the terminal 28 can pass through the clamping end 28 through the setting of the stop piece 50. When the elongated slot 52 enters the receiving portion 42, the shoulder 283 between the clamping end 281 and the terminal wire end 282 can just resist against the blocking piece 50 facing each of the clamping teeth 24. On the end surface 54, it has a certain outward extension length.

Please refer to Fig. 4 and 5 again, it is another preferred embodiment of the present utility model, wherein also can be respectively provided with a second perforation 48 on the fixing part 44 of each said positioning piece 40, and on the side of this terminal clamp 20 Then be provided with several screw holes 23 respectively corresponding to each of the clamping teeth 24, and the screws 45 respectively screwed in each of the screw holes 23; It can be worn on each of the screws 45, and an elongated hole 49 extending upwards to a predetermined length is provided on its side. The inner diameter of the elongated hole 49 is smaller than the outer diameter of the head end of each screw 45 but smaller than its shaft. It is large, so that each of the screws 45 can be pre-screwed in each of the screw holes 23 on the side of the terminal clamp 20, so that each of the positioning pieces 40 can be inserted through each of the second through holes 48 on it. On it, be tightened again, and each this screw 45 need not be unloaded. The widths of the openings 46 of the openings 46 of the receiving portions 42 on the positioning pieces 40 are different, so that the terminals 28 of various sizes can be inserted therein.

Each accommodating portion 42 corresponds to the outer end of each of the clamping teeth 24, and on the closed end 60 on the other side opposite to each of the opening ends 46, a screw is provided with an axial direction and the axial direction of the accommodating portion 42. The parallel adjusting screw 62, by changing the length of the adjusting screw 62 whose tail end 64 extends into the receiving portion 42, can be used to adjust the depth of the receiving chamber 42 for the terminal 28 to penetrate therein, so that it can be used Various terminals 28 with different lengths at the clamping end 281 .

Referring to Figs. 6 and 7 again, the terminal positioning device 21 of the present utility model is further provided with a post 66 integrally formed in the center of the bottom end 43 of the accommodating portion 42, and the post 66 extends vertically upward for an appropriate length. And do not contact with the top end 47 of the accommodating portion, so that the upper end is hollow, so that the clamping end 281 of the “Y” or “O”-shaped terminal 28 is accommodated in the accommodating portion 42 When it is in the center, the terminal 28 can be positioned against the post 66 with its outwardly facing fork 284 or axis 285, and the two opposite sides 68 of the receiving portion 42 can be turned towards each other. The end 681 of the terminal clamp 20 is slightly arc-shaped to change the inner shape of the receiving portion 42, making it more suitable for the terminal 28 whose clamping end 281 is an “O” shape.

To sum up, the utility model utilizes a housing part that can be locked mechanically outside the side ends of each clamping tooth of the terminal pliers, so that one end of each terminal to be clamped can be put through it, so as to prevent deflection and slippage. For the purpose of shifting, its practicability and novelty should be affirmed.
