[0030] Example:
[0031] As attached Figure 1 To Attachment Figure 8 As shown:
[0032] The utility model provides a single - pole IEC output socket with an anti - detachment device, which comprises a main housing 1. A slot 101 is arranged at the top of the main housing 1. A boss 102 is arranged inside the slot 101. Three jacks 103 are arranged at the top of the boss 102. Three polar terminals 3 are installed inside the three jacks 103. It is characterized in that: Anti - detachment doors 2 are installed on the left and right sides of the top of the main housing 1 near the slot 101. At both ends of the bottom of the anti - detachment door 2, connecting plates 201 are arranged. At one side of the bottom end of the connecting plate 201, trapezoidal blocks 202 are arranged; Connection grooves 105 are arranged at the four corners of the top of the main housing 1. The connecting plates 201 are respectively installed inside the connection grooves 105. The trapezoidal blocks 202 are arranged at the bottom side of the connection grooves 105 and are in contact with the main housing 1; An avoidance groove 106 for the trapezoidal block 202 to insert is arranged on the side of the outermost end of the connection groove 105 close to the main housing 1, so that during production and assembly, the connecting plate 201 and the trapezoidal block 202 can be quickly inserted into the connection groove 105. After insertion, due to the action of the trapezoidal block 202, it is ensured that the anti - detachment door 2 will not easily fall off; A stop block 107 for restricting the movement of the connecting plate 201 is arranged on the side of the connection groove 105 opposite to the avoidance groove 106.
[0033] Among them, the stop block 107 is a semi - circular column and is an integrally injection - molded structure with the main housing 1, so that when the anti - detachment door 2 is pushed to move, the connecting plate 201 can be bent backward smoothly against the stop block 107 until it passes through the stop block 107. After passing through, the anti - detachment door 2 can be closed or opened to fasten and loosen the plug.
[0034] Among them, retaining strips 104 are arranged at both ends of the top of the main housing 1 near the anti - detachment door 2. The retaining strips 104 are in sliding contact with the anti - detachment door 2. The retaining strips 104 are arranged at the edge of the main housing 1 and are arranged along the moving direction of the anti - detachment door 2, so as to improve the stability and smoothness of the anti - detachment door 2 during movement.
[0035] Among them, the inclined surface of the trapezoidal block 202 is arranged at its bottom end and faces outward, so that when the trapezoidal block 202 comes into initial contact with the connection groove 105, the connecting plate 201 can be compressed and bent through the inclined surface at its bottom end, which is beneficial to the quick insertion of the connecting plate 201. After insertion, the connecting plate 201 returns to its original state, and through the straight surface at the top of the trapezoidal block 202, it completes the contact and clamping with the main housing 1 to prevent the anti - detachment door 2 from falling or detaching.
[0036] Among them, the anti - detachment door 2 is in a C - shape, and the openings of the two anti - detachment doors 2 are arranged oppositely to quickly lock the side of the plug and prevent it from detaching from the main housing 1 due to vibration and other environmental factors during use.
[0037] Among them, the connecting plate 201 and the trapezoidal block 202 are an integrated injection molding structure with the anti-slip door 2 to reduce processing costs and facilitate production. At the same time, the plastic has good elasticity, which is conducive to the rapid adjustment of the connecting plate 201 in the connecting groove 105, which is more convenient to use.
[0038] Among them, one end of the polarity terminal 3 is provided with two groups of relatively arranged connecting pins 301, and the connecting pins 301 are arranged inside the jack 103; the other end of the polarity terminal 3 is arranged on the outside of the jack 103, and a connecting hole 302 is arranged on the side of the end, so that when in use, it can achieve the effect of threading copper wire, hooking wire, and quick insertion; the connecting pins 301 and the polarity terminal 3 are an integrated structure.
[0039] A plurality of groups of mounting buckles 108 are disposed on the side of the main housing 1 , so as to facilitate rapid installation of the main housing 1 into an existing fixed housing or panel.
[0040] The working principle of this embodiment is as follows: when in use, first insert the plug into the slot 101 of the main shell 1, then pinch the two anti-drop doors 2 with your fingers at the same time and move them toward the plug. When the anti-drop door 2 moves, the connecting plate 201 at its bottom will contact the block 107. When in contact, the edge of the connecting plate 201 will be affected by its arc surface and bend to one side until it passes the most convex point of the block 107. Then, under the action of its own elasticity, it will move along the arc surface on the other side of the block 107 toward the side of the connecting groove 105 until it completely passes the block 107. Then, it will be tightly attached to the side of the connecting groove 105. At this time, the anti-drop door 2 moves to the side of the plug and clamps it stably to prevent the plug from falling off during use.
