Description

Technical Field

[0001] The present application relates to the technical field of terminal detection equipment, and in particular to a terminal pre-injection molding detection tool. Background Art

[0002] A terminal is a device or component used to connect wires or conductors. It is usually made of metal material, has conductive properties, and provides a reliable electrical connection point. Terminals are usually used in electronic equipment, electrical equipment, power systems and other fields to connect power supplies, signal lines, sensors, switches and other electrical components.

[0003] Reference Figure 1 For some non-standard plugs, which include internal metal terminals and plastic bodies injected outside, it is difficult to fix the position of the metal terminals during the injection molding process. The current method is mainly to fix the metal terminals on the positioning parts, where the whole formed by the metal terminals and the positioning parts is called an intermediate. The intermediate is then placed in a mold for injection molding to complete the production of the product.

[0004] Regarding the above-mentioned related technologies, since there is metal stress inside the metal terminal, the end is prone to deformation, and there is a lack of terminal detection process before injection molding. After subsequent injection molding, the finished product is difficult to meet the demand, thus forming a defective product. Utility Model Content

[0032] Reference Figure 2 and Figure 3 The support member 1 includes a detection plate 11 and a limit rod 12. The detection plate 11 is horizontally arranged. A sliding groove is opened at one end of the detection plate 11. The sliding groove opens the upper end surface of the detection plate 11. The sliding groove extends along the length direction of the detection plate 11. The fixing member 2 is arranged at the end of the detection plate 11 away from the sliding groove. The sliding block 3 is arranged at the sliding groove of the detection plate 11. The bottom end of the metal terminal 110 is connected to the fixing member 2, and the other end is arranged opposite to the sliding block 3. The limit rod 12 is arranged at the end of the detection plate 11 away from the fixing member 2. The limit rod 12 is vertically arranged with the detection plate 11, and the limit rod 12 is located at the sliding groove of the detection plate 11.

[0033] Reference Figure 2 and Figure 3 By setting the limit rod 12, the sliding block 3 can be prevented from falling off the tooling, which is beneficial to improving the stability of the structure. When it is necessary to detect whether the end part of the metal terminal 110 is deformed, the staff first inserts the lower end of the metal terminal 110 into the fixing member 2, and then moves the sliding block 3 to observe whether the other end of the metal terminal 110 matches the sliding block 3, thereby judging whether the metal terminal 110 is qualified, eliminating product quality problems before injection molding, improving the yield rate, and reducing the waste of production resources.

[0034] Reference Figure 2 and Figure 3The fixing member 2 includes a fixing mold 21, a fixing block 22 and a clamping block 23. An insertion hole is provided at one end of the detection plate 11 away from the limit rod 12. The fixing mold 21 is located at the insertion hole of the detection plate 11. A fixing hole for fixing the metal terminal 110 is provided on the fixing mold 21. The fixing block 22 is arranged at the bottom end of the fixing mold 21. The fixing block 22 is fixedly connected to the fixing mold 21. A positioning groove is provided at one end of the detection plate 11 close to the fixing mold 21. The positioning groove is arranged on the lower end surface of the detection plate 11. The fixing block 22 is located at the positioning groove of the detection plate 11.

The clamping groove is respectively connected with the positioning groove and the insertion hole of the detection plate 11. The clamping block 23 is arranged on one side of the fixing mold 21 close to the fixing block 22. The clamping block 23 is located at the clamping groove of the detection plate 11.

[0035] Reference Figure 2 and Figure 3 When the fixed mold 21 needs to be installed, the staff inserts the fixed block 22 with the fixed mold 21 from the positioning groove of the detection plate 11, and clamps it to the clamping groove of the detection plate 11 through the clamping block 23, and fixes it with bolts to achieve a detachable connection of the fixed mold 21, which is convenient for replacement and maintenance of the fixed mold 21.

[0036] Reference Figure 2 and Figure 3 The sliding block 3 includes an upper slider 31 and a lower slider 32. The lower slider 32 is slidably connected to the sliding groove of the detection plate 11. The upper slider 31 and the lower slider 32 are arranged alternately. A detection groove is provided on the side of the upper slider 31 close to the metal fixed mold 21. A socket mold 37 is provided at the detection groove of the upper slider 31. The socket mold 37 is provided with an insertion hole for detecting whether the end of the metal terminal 110 is qualified. One end of the metal terminal 110 is located at the fixing hole of the fixed mold 21, and the other end is aligned with the insertion hole of the socket mold 37. A fixing groove is provided on the upper end surface of the upper slider 31. A locking bolt 33 is provided at the fixing groove. The locking bolt 33 is abutted against the socket mold 37. The socket mold 37 is slidably connected to the detection groove of the upper slider 31.

[0037] Reference Figure 2 and Figure 3 Due to the staggered arrangement of the upper slider 31 and the lower slider 32, the length of the sliding groove of the detection plate 11 can be reduced to achieve the same detection effect, which is beneficial to saving the area occupied by the tooling, and the socket mold 37 is detachably connected to the detection groove of the sliding block 3, which is convenient for replacement and maintenance. When the socket mold 37 is set at the detection groove of the sliding block 3, the staff twists the tightening bolt to tighten the socket mold 37, which is beneficial to enhance the stability of the socket mold 37, thereby improving the stability of the tooling and improving the accuracy of detection.

[0038] Reference Figure 2 and Figure 3 Both ends of the detection plate 11 are provided with slide rails 34, and the two slide rails 34 are relatively arranged at the sliding groove of the detection plate 11.

The slide rails 34 and the detection plate 11 are detachably connected by bolts, and the peripheries of the two slide rails 34 are provided with chamfers 36.

[0039] Reference Figure 2 and Figure 3 By setting the chamfer 36, the damage to the object caused by sharp edges or corners can be reduced; by providing a limiting groove on the slide rail 34, the lower slide block 32 can be made more stable during the movement, thereby making the detection process more stable, which is conducive to improving the accuracy of the detection result.
