Description

Technical Field

[0001] The utility model relates to the technical field of plug testing equipment, in particular to a plug testing jig with ejector pins. Background Art

[0002] As shown in conventional existing plugs Figure 1 and Figure 2 , the plug mainly comprises a plug body 100 made of plastic insulation, an inner frame 300 for fixing the insert pieces 200 is arranged at the front end of the plug body 100, and two metal insert pieces 200 arranged side by side at intervals are fixed on the inner frame 300 and protrude forward. In the actual production process of the plug, a plugging test needs to be performed on the two metal insert pieces 200 mounted on the inner frame 300 at the front end of the plug body 100, so as to ensure that the distance a between the two metal insert pieces 200 meets the design requirements of the manufacturer, and avoid that the plug cannot be smoothly plugged and unplugged because the distance a between the two metal insert pieces 200 is too large or too small. The existing testing jig is very simple, that is, two insert piece measuring holes 2 are arranged on the jig body 1, the distance between the two insert piece measuring holes 2 is set to a, which is the same as the distance a between the two metal insert pieces 200 on the plug, and then the plugging test is carried out. If the distance a between the two metal insert pieces 200 on the plug meets the requirements, the two metal insert pieces can be inserted into the two insert piece measuring holes 2, and the plug is qualified at this time. If the two metal insert pieces 200 of the plug cannot be inserted into the two insert piece measuring holes 2, the plug is judged to be unqualified. However, in practical applications, it is found that since the factory needs to test tens of thousands of plugs a day, it is very easy to mix qualified tested plugs and unqualified plugs, or tested plugs and untested plugs, which makes it impossible for the inspectors to correctly distinguish qualified tested plugs, unqualified plugs, untested plugs and the like, so improvements are needed. Contents of the Utility Model

[0003] In view of the deficiencies in the prior art, the utility model provides a plug testing jig with ejector pins. By arranging the ejector pins on the jig body, the inspectors can greatly and conveniently quickly and correctly distinguish qualified tested plugs from unqualified plugs or untested plugs.

[0004] To achieve the above technical solution, the utility model provides a plug testing jig with ejector pins, comprising: a jig body, wherein two insert piece measuring holes distributed in parallel at intervals are formed on the jig body, and an ejector pin protruding outward by 0.2-1mm is arranged on the jig body on the center line of the two insert piece measuring holes.

[0005] In the above technical solution, during actual operation, when the metal prongs of a qualified plug are inserted into the two prong measuring holes on the fixture body, a pin on the fixture body will leave a pin mark on the inner frame of the plug body. This allows subsequent inspectors to determine whether the plug is qualified based on the pin mark on the inner frame, greatly facilitating the quick and accurate differentiation between qualified, unqualified, or untested plugs. Furthermore, the outward protrusion distance of the pin has a significant impact on the inner frame. If the outward protrusion distance is too small, it is difficult to leave a pin mark on the inner frame, hindering the inspector's judgment; if the outward protrusion distance is too large, it will damage the inner frame, resulting in a defective product. Experiments have shown that when the outward protrusion distance of the pin is set to 0.2-1mm, a clear pin mark is left on the inner frame without damaging it.

[0006] Preferably, the ejector pin is positioned near the lower edge of the center line of the inner frame at the front end of the plug body. Experiments have shown that the position of the ejector pin also affects the retention of the pin mark. If the ejector pin is positioned in the center, the pin mark is more difficult to detect, and it causes greater damage to the inner frame. When the ejector pin is positioned near the lower edge of the center line of the inner frame at the front end of the plug body, the pin mark is more obvious, and the damage to the inner frame is less.

[0007] Preferably, the ejector pin protrudes outward by 0.5mm. Experiments have shown that when the ejector pin protrudes outward by 0.5mm, it leaves a clear ejector pin mark on the inner frame without damaging it, achieving the best effect.

[0008] Preferably, the ejector pin is made of stainless steel. Stainless steel has high hardness and a long service life.

[0009] The beneficial effects of the plug testing fixture with a pin provided by this utility model are as follows: This plug testing fixture with a pin has a simple structure and ingenious design, requiring no complex modifications and is very convenient to operate. In actual operation, when the metal prongs of a qualified plug are inserted into the two prong measuring holes opened on the fixture body, the pin set on the fixture body will leave a pin mark on the inner frame of the plug body. This allows subsequent testing personnel to determine whether the plug is qualified based on the pin mark on the inner frame. Unqualified plugs will not leave a pin mark. Therefore, testing personnel can quickly and correctly distinguish between qualified plugs, unqualified plugs, or untested plugs simply by whether there is a pin mark on the inner frame of the plug.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: A plug testing fixture with a pin.

[0018] Reference Figures 1 to 3 As shown, a plug testing fixture with a pin includes: a fixture body 1, on which two parallel, spaced-apart prong measuring holes 2 are formed; and a pin 3, protruding 0.5 mm outward, is disposed on the fixture body 1 along the center line of the two prong measuring holes 2. The pin 3 is positioned near the lower edge of the center line of the inner frame 300 at the front end of the plug body 100. Experiments have shown that the position of the pin 3 has a certain impact on the retention of the pin mark 400. If the pin 3 is placed in the center, the pin mark 400 is more difficult to find, and it causes greater damage to the inner frame 300. When the pin 3 is placed near the lower edge of the center line of the inner frame 300 at the front end of the plug body 100, the pin mark 400 is more obvious, and the damage to the inner frame 300 is less. The pin 3 is made of stainless steel, which has high hardness and a long service life.

[0019] In this embodiment, during actual operation, when the metal prongs 200 of a qualified plug are inserted into the two prong measuring holes 2 on the fixture body 1, a pin mark 400 will be left on the inner frame 300 of the plug body 100 by the pin 3 set on the fixture body 1. This allows subsequent testing personnel to determine whether the plug is qualified based on the pin mark 400 on the inner frame 300. Unqualified plugs will not leave a pin mark 400. Therefore, testing personnel can quickly and correctly distinguish between qualified plugs and unqualified or untested plugs by the presence or absence of a pin mark 400 on the inner frame 300 of the plug. This greatly facilitates testing personnel in quickly and correctly distinguishing between qualified plugs and unqualified or untested plugs.

[0020] In practice, it was found that the outward protrusion distance of ejector pin 3 has a significant impact on the inner frame 300. If the outward protrusion distance of ejector pin 3 is too small, it is difficult to leave an ejector pin mark 400 on the inner frame 300, making it inconvenient for inspectors to judge. If the outward protrusion distance of ejector pin 3 is too large, it will damage the inner frame 300, resulting in product defects. Experiments have shown that when the outward protrusion distance of ejector pin 3 is set to 0.5mm, it leaves a clear ejector pin mark 400 on the inner frame 300 without damaging it, achieving the best effect.

[0021] This plug testing fixture with a pin has a simple structure and ingenious design. It requires no complicated modifications and is very easy to operate. By setting the pin 3 on the fixture body 1, it greatly facilitates the testing personnel to quickly and correctly distinguish between qualified plugs and unqualified plugs or untested plugs.

[0022] The above description is only a preferred embodiment of the present utility model. However, the present utility model should not be limited to the content disclosed in the embodiment and the accompanying drawings. Therefore, any equivalent or modified embodiments made without departing from the spirit disclosed in the present utility model shall fall within the protection scope of the present utility model.
