DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the utility model comprises an outer shell 3, a fixing frame 2 and a control module 1, wherein the outer shell 3 is fixed on the device body, the fixing frame 2 is installed on the outer shell 3, and as shown in FIG. Figures 3 to 5 As shown, the fixing frame 2 is concave and has slide grooves on both sides inside, and a card hole 203 is provided at the lower end of the slide groove side 202 of the slide groove, and plug-in parts 102 are provided on both sides of the control module 1, and an elastic arm 1021 is provided on the lower side of the plug-in part 102, and a card block 1022 is provided on the outer side of the lower end of the elastic arm 1021. The control module 1 is inserted from the open side of the fixing frame 2, and after insertion, the plug-in part 102 slides along the corresponding side slide groove until the card block 1022 is inserted into the card hole 203 on the corresponding side to realize the fixed connection between the control module 1 and the fixing frame 2, and an elastic contact element is provided at the front end of the control module 1 to realize electrical connection with the electrical circuit on the outer shell 3.

[0030] like Figure 4 As shown, the slide groove includes a slide groove bottom surface 201 and a slide groove side surface 202 which are perpendicular to each other, and when the control module 1 is inserted into the fixing frame 2, the bottom surface of the plug-in portion 102 moves along the slide groove bottom surface 201, and the plug-in portion side wall 1023 outside the plug-in portion 102 moves along the slide groove side surface 202. After the control module 1 is moved into place, in addition to using the lower end block 1022 to cooperate with the card hole 203 to achieve height limitation, the bottom surface of the plug-in portion 102 and the slide groove bottom surface 201 are abutted against each other for limitation. At the same time, mounting holes 204 are provided on both sides of the fixing frame 2 and are fixed to the outer shell 3 by bolts. In this way, the outer surface of the outer shell 3 and the slide groove bottom surface 201 cooperate to achieve the limitation of the plug-in portion 102 along the central axis direction of the control module 1.

[0031] like Figures 3-4As shown, the upper end of the plug-in side wall 1023 is provided with an inner inclined surface 10231, and the lower end of the slide groove bottom surface 201 is an arc 2011, which can facilitate the upward insertion of the control module 1. Figure 5 As shown, a gap 103 is formed between the elastic arm 1021 and the control module 1 , so that when the control module 1 is inserted into the fixing frame 2 , the elastic arm 1021 will perform adaptive inward swing deformation until the clamping block 1022 is embedded in the clamping hole 203 .

[0032] The front end of the control module 1 is provided with an elastic contact element to realize electrical connection with the electrical circuit in the outer shell 3. The utility model can select different elastic contact element structures according to actual needs.

[0033] like Figure 2 As shown, in one embodiment of the present invention, an electrical jack 301 is provided on the outer side of the outer shell 3 to connect with the electrical circuit thereon, and as shown in FIG. Figure 3 and Figure 5 As shown, the elastic contact element at the front end of the control module 1 is an elastic contact rod 101 to facilitate the installation needs of different equipment bodies. For example, some equipment bodies need to first fix the outer shell 3, then fix the fixing frame 2 on the outer shell 3, and then insert the control module 1 into the fixing frame 2 to achieve fixation. In the process of inserting the control module 1 upward into the fixing frame 2, the elastic contact rod 101 first shrinks and retreats, and when the control module 1 is inserted into place, the elastic contact rod 101 can automatically spring into the electrical jack 301 on the outer shell 3, and ensure a secure connection with the electrical jack 301 through elastic force. The utility model can also first insert the control module 1 on the fixing frame 2, and then fix the fixing frame 2 together with the control module 1 on the outer shell 3.

[0034] like Figure 6 As shown, in this embodiment, the part of the elastic touch rod 101 located in the housing of the control module 1 is provided with a baffle 1011 and a spring 1012, and the spring 1012 is provided between the baffle 1011 and the adjacent module group, the module group is provided with a slot for the rear end of the elastic touch rod 101 to be inserted, and the rear end of the elastic touch rod 101 is provided with a connecting line 1013 to be electrically connected to the corresponding contact on the module group, the connecting line 1013 needs to have a sufficient length to ensure the telescopic movement of the elastic touch rod 101, when the elastic touch rod 101 is compressed and moved backward, the baffle 1011 moves backward synchronously and compresses the spring 1012, when the pressure on the elastic touch rod 101 disappears, the spring 1012 drives the baffle 1011 to move forward, and then drives the elastic touch rod 101 to move forward.

[0035] And as Figure 7As shown, in another embodiment of the utility model, the outer shell 3 is provided with a contact bolt 302 connected to the electrical circuit thereon, and the nut of the contact bolt 302 is provided with a contact groove 3021, and the elastic contact element at the front end of the control module 1 is a spring 1041, which is provided on a spring module 104 and installed on the control module 1 through the spring module 104, and the spring 1041 is a metal spring. When the control module 1 is inserted upward into the fixing frame 2, the spring 1041 is first compressed by the outer surface of the outer shell 3, and when the spring 1041 enters the contact groove 3021, it will automatically pop up and contact the bottom of the contact groove 3021 to achieve electrical connection, and the bottom of the contact groove 3021 will apply a certain pressure to the spring 1041 to ensure that the two are in close contact, thereby ensuring a reliable electrical connection, and at the same time, the spring 1041 has a certain elasticity and is more convenient for it to move in or out of the contact groove 3021. In addition, when this embodiment is used, the spring piece 1041 can also directly contact the nut of the contact bolt 302 to achieve electrical connection, or the cooperation between the spring piece 1041 and the contact bolt 302 can also select other appropriate structural methods according to specific circumstances.

However, as Figure 7 As shown, the current transformer 4, the opening and closing mechanism 7 and other mechanisms are mainly concentrated on the upper end of the switch body. For the convenience of control and the aesthetic appearance of the product, the control module 1 also needs to be arranged on the upper end of the outdoor pole switch. In addition, if the control module 1 is directly connected to the outdoor pole switch, it is not conducive to the installation and maintenance of the device. Therefore, the utility model installs the control module 1 detachably on the outdoor pole switch.

[0040] In addition, Figure 5 As shown, the utility model is provided with an inner inclined surface 10231 at the upper end of the plug-in side wall 1023, and the lower end of the bottom surface 201 of the slide groove is designed to be an arc 2011, so that the control module 1 can be inserted upwards conveniently. Figures 6-7 As shown, the control module 1 of the utility model adopts elastic contact elements such as elastic contact rods 101 or springs 1041 to cooperate with the outer shell 3 to achieve electrical connection, wherein during the process of inserting the control module 1 upward into the fixing frame 2, the elastic contact element is compressed and retreated, and after the control module 1 is inserted into place, the elastic contact element automatically pops out and contacts with the corresponding part on the outer shell 3.

[0041] The outer shell 3 is detachably arranged outside the opening and closing mechanism cavity, which can facilitate the installation of the control module 1 on the one hand, and also facilitate the installation and maintenance of the opening and closing mechanism in the cavity on the other hand.

[0042] The utility model can also be installed on other electric devices as required.
