Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical component technology, specifically to a plug-in secondary connector. Background Technology
[0002] Connectors, also known as plugs and sockets in China, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. Secondary connectors are mainly used in secondary control circuits in distribution cabinets. They typically consist of male and female contacts forming a contact pair, with electrical connection achieved through the mating of the male and female contacts. In low-voltage withdrawable switchgear, a drawer-type connection device is used, where the moving contacts are installed below the drawer, and the stationary contacts are installed on the cabinet above the drawer. The stationary connector connects to external cables. As the drawer moves in and out, the power supply to the control circuit is switched on or off, thus connecting or disconnecting the circuit.
[0003] Existing secondary connectors, such as the Chinese utility model patent CN217522328U which discloses a hanging frame wiring type secondary connector, include a plug and a socket. Conductors extending along the insertion direction are provided on the upper and lower sides of the socket and plug. Terminals are provided at the ends of the two conductors in the socket furthest from the plug, and at the ends of the two conductors in the plug furthest from the socket. Wiring structures are provided on the socket housing corresponding to the two terminal positions, and on the plug housing corresponding to the two terminal positions. Each wiring structure includes a frame for the corresponding terminal to enter and a movable component rotatably connected to the corresponding housing and the corresponding frame. The movable component is a screw structure, and the terminal is angled to the insertion direction. In this technical solution, wiring requires the use of a wiring frame and screws to fix the wires, and loosening the screws is required to remove the wires. The structure is complex, and wiring and unwielding are cumbersome. Therefore, it is necessary to improve this design. Utility Model Content

Detailed Implementation
[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0043] This utility model provides a direct-plug secondary connector, see [link to relevant documentation]. Figures 1 to 9It mainly includes a moving contact 10 and a stationary contact 20. The moving contact 10 includes a first housing 11 and one end connected to the first housing 11. Figure 1 or Figure 2 The example shown is an insert portion 12 integrally formed at the right end and extending outward. That is, the moving contact 10 is generally T-shaped. The center line of the first housing 11 coincides with the center line of the insert portion 12. The stationary contact 20 includes a second housing 21 and an inwardly recessed slot 22 formed at one end of the second housing 21 for the insert portion 12 to be inserted into. That is, the stationary contact 20 is generally U-shaped. The center line of the second housing 21 coincides with the center line of the slot 22, and when the moving contact 10 is inserted into the stationary contact 20, the center lines of the first housing 11 and the second housing 21 also coincide. The moving contact 10 is provided with two first conductive elements 13 and two second conductive elements 14, wherein the two first conductive elements 13 are provided in the first housing 11 and on both sides along the center line direction of the first housing 11. Figure 2 The two second conductive elements 14 are distributed on both sides (top and bottom) along the extension direction of the insertion portion 12. Figure 2 The middle part is distributed on both the top and bottom sides, and any second conductive element 14 is also... Figure 2 The right end portion is located within the first housing 11. The stationary contact 20 contains two third conductive elements 23 and two fourth conductive elements 24. The two third conductive elements 23 are located on both sides of the end of the second housing 21 furthest from the slot 22. Figure 4 The two fourth conductive elements 24 are distributed on both sides of the extension direction of the slot 22 (top and bottom). Figure 4 The first housing 11 has two first wiring holes 111, specifically, the end of the first housing 11 furthest from the insertion part 12 is as follows: Figure 2 The two sides of the left end shown ( Figure 2 The upper and lower sides of the middle section each have inwardly recessed sections that extend along the centerline of the second shell 21. Figure 2 The first wiring hole 111 extends to the right in a recessed manner, as shown. Similarly, two second wiring holes 211 are provided inside the second housing 21, specifically, on both sides of the end of the second housing 21 away from the slot 22 ( Figure 4 The upper and lower sides of the middle section each have inwardly recessed sections that extend along the centerline of the second shell 21. Figure 4The second wiring hole 211 extends to the left in a recessed manner, as shown. It should be noted that the first conductive element 13, the second conductive element 14, the third conductive element 23, and the fourth conductive element 24 in this embodiment are all conventional metal conductive springs in the prior art, capable of deformation under external force, for example, 2.5 Nm. For any first conductive element 13, it is approximately L-shaped when no wire 30 is connected and approximately V-shaped after the wire 30 is connected. Specifically, the first conductive element 13 has a first end 131 and a second end 132 forming an angle (the specific angle is not described or limited, but is preferably acute, for example, approximately 80° when no wire 30 is connected and approximately 60° after the wire 30 is connected). The first end 131 of any first conductive element 13 faces away from the other first conductive element 13, that is... Figure 2 The first end 131 of the first conductive element 13 on the upper side faces upward and Figure 2 The first end 131 of the first conductive element 13 on the lower side faces downward. In this embodiment of the present invention, the first end 131 of any conductive element is located at the inner end of the first wiring hole 111 on its corresponding side, and any first end 131 abuts against the second conductive element 14 on its corresponding side and can be bent and deformed in the direction of its corresponding second end 132 under the action of external force to separate from the second conductive element 14. Specifically, when no wire 30 is inserted into any of the first wiring holes 111, the first end 131 of the corresponding first conductive member 13 blocks the first wiring hole 111, and its end abuts against the second conductive member 14 on the corresponding side of the first conductive member 13 to form an electrical contact. After a wire 30 is inserted into any of the first wiring holes 111, the first end 131 of the first conductive member 13 on the corresponding side of the first wiring hole 111 is deformed towards its second end 132 by the insertion force of the wire 30 until the upper and lower sides of the wire 30 respectively contact the end of the first end 131 of the first conductive member 13 and the end of the second conductive member 14 located in the first housing 11 to form an electrical connection. That is, the wire 30 is fixed between the first conductive member 13 and the second conductive member 14 by the pressure of the first end 131 of the first conductive member 13. Similarly, the shape and structure of the third conductive member 23 are similar to those of the first conductive member 13. That is, any third conductive element 23 forms an approximate L-shape when no wire 30 is connected in the second wiring hole 211, and an approximate V-shape when a wire 30 is inserted into the second wiring hole 211. Specifically, any third conductive element 23 has a third end 231 and a fourth end 232 forming an angle (the specific angle is not described or limited, but is preferably acute; see the description of the first conductive element 13, and will not be repeated here). The third end 231 of any third conductive element 23 faces away from the other third conductive element 23, that is... Figure 4 The third end 231 of the third conductive element 23 on the upper middle side faces upward and Figure 4The third end 231 of the third conductive member 23 on the lower side faces downward. Similarly, any fourth conductive member 24 extends into the end of the second housing 21 away from the slot 22. And any third end 231 abuts against the fourth conductive member 24 on its corresponding side and can be bent and deformed towards its corresponding fourth end 232 under the action of external force to separate from the fourth conductive member 24. Specifically, when no wire 30 is inserted into any of the second wiring holes 211, the third end 231 of the corresponding third conductive member 23 blocks the second wiring hole 211, and its end abuts against the fourth conductive member 24 on the corresponding side of the third conductive member 23 to form an electrical contact. After a wire 30 is inserted into any of the second wiring holes 211, the third end 231 of the third conductive member 23 on the corresponding side of the second wiring hole 211 is deformed towards its fourth end 232 by the insertion force of the wire 30 until the upper and lower sides of the wire 30 respectively contact the end of the third end 231 of the third conductive member 23 and the end of the fourth conductive member 24 located in the second housing 21 away from the slot 22 to form an electrical connection. That is, the wire 30 is fixed between the third conductive member 23 and the fourth conductive member 24 by the pressure of the third end 231 of the third conductive member 23. The wire 30 in this embodiment of the present invention is a tubular terminal type wire 30. In summary, the secondary connector of this utility model extends along the center line of the first housing 111 and the second housing 211, respectively. The wire 30 is directly inserted, and the first end 131 of the first conductive member 13 and the third end 231 of the second conductive member 14 are deformed by the pushing force of the wire 30. After the wire 30 is connected, it is fixed by the elastic deformation of the first end 131 of the first conductive member 13 and the third end 231 of the second conductive member 14. The structure is simple and the wire 30 connection is easy and labor-saving, and it is highly practical.
[0044] like Figure 2 As shown, the end of any second conductive element 14 disposed within the first housing 11 is farther from the center line of the first housing 11 or the insertion portion 12 than the end disposed on the insertion portion 12. Specifically, any second conductive element 14 is approximately Z-shaped, i.e., as shown... Figure 2 The right end is higher than the left end, as shown. More specifically, as... Figure 2 and Figure 3 As shown, the direction from near the insertion part 12 to away from the insertion part 12 is also as follows: Figure 3In the right-to-left direction shown, one end of any second conductive element 14 disposed within the first housing 11 sequentially includes a first segment 141, a second segment 142, and a third segment 143. The first segment 141 is perpendicular to the centerline of the first housing 11, the second segment 142 is parallel to the centerline of the first housing 11, and the third segment 143 is disposed at an angle to the second segment 142 (the specific angle is not described or limited, but is preferably obtuse, for example, 120°), and the third segment 143 extends obliquely away from the other second conductive element 14. That is, Figure 2 The third segment 143 of the second conductive element 14 on the upper middle side extends obliquely to the upper left. Figure 2 The third segment 143 of the second conductive member 14 on the lower middle side extends obliquely to the lower left. A first limiting portion 144 protruding towards the centerline of the first housing 11 is formed between the third segment 143 and the second segment 142 of any second conductive member 14. That is, with... Figure 2 Taking the second conductive member 14 on the upper side as an example, the left end of the second segment 142 extends downwards and to the left, forming a slope that connects to the third segment 143. This inclined slope serves as the first limiting part 144. When no wire 30 is inserted into any of the first wiring holes 111, the first end 131 of the first conductive member 13 in the first wiring hole 111 is adapted to abut against the first limiting part 144. Since the first end 131 of the first conductive member 13 has an elastic deformation force, the first limiting part 144 forms a limit on the first end 131 of the first conductive member 13, which can also reduce the pushing force when the wire 30 is inserted. The portion of any second conductive member 14 located on the insertion part 12 is not specifically described or limited. Optionally, such as Figure 2 The upper second conductive member 14 shown has a portion, specifically the right end portion, that protrudes upward, thereby forming a break section (not shown) on the left end portion of the upper second conductive member 14 on the insertion portion 12. This break section is located inside the insertion portion 12, that is, an insulating layer is provided outside the break section to achieve a disconnection effect. The specific details are not described or limited, and this is a conventional design known to those skilled in the art, and is not an innovation of this utility model.
[0045] Similarly, any fourth conductive element 24 is disposed within the second housing 21 at the end furthest from the slot 22, i.e. Figure 4 The distance from the right end to the center line of the second housing 21 or slot 22 shown is relative to one side of slot 22. Figure 4 The middle (either the upper or lower side) is also like... Figure 4 The left end shown is farther from the center line of the second housing 21 or slot 22. And the direction from near slot 22 to far away from slot 22 is as follows... Figure 4 or Figure 5In the left-to-right direction shown, each of the fourth conductive elements 24, located at one end of the second housing 21 away from the slot 22, sequentially includes a fourth segment 241 and a fifth segment 242. The fourth segment 241 is parallel to the centerline of the second housing 21, and the fifth segment 242 is set at an angle to the fourth segment (the specific angle is not described or limited, but is preferably an obtuse angle, such as 120°). A second limiting portion 243 protruding towards the centerline of the second housing 21 is formed between the fifth segment 242 and the fourth segment 241, i.e., as shown... Figure 4 The fifth segment 242 of the third conductive element 23 on the upper side extends obliquely to the upper right, as shown. Figure 4 The fifth segment 242 of the third conductive element 23 shown on the lower side extends obliquely to the lower right. That is to say, with Figure 4 Taking the fourth conductive member 24 on the upper middle side as an example, the right end of the fourth segment 241 extends downwards and to the right, forming a slope that connects to the fifth segment 242. This sloped extension serves as the second limiting part 243. When no wire 30 is inserted into any of the second wiring holes 211, the third end 231 of the third conductive member 23 in the second wiring hole 211 is adapted to abut against the second limiting part 243. Since the third end 231 of the third conductive member 23 has an elastic deformation force, the second limiting part 243 limits the third end 231 of the third conductive member 23, thereby reducing the pushing force when the wire 30 is inserted. The shape of the portion of any fourth conductive member 24 located on one side of the slot 22 is not described or limited; in this embodiment, it is exemplarily √-shaped.
[0046] Furthermore, such as Figure 2 As shown, the end of the first housing 11 furthest from the insertion portion 12 is also as follows Figure 2 The left end shown is located on both sides along the centerline of the first housing 11, i.e. Figure 2Each of the upper and lower sides has an inwardly recessed first hole 112 extending along the centerline of the first housing 11. The extension direction of any first hole 112 intersects the first end 131 of the first conductive member 13 on its corresponding side, that is, the inner end of any first hole 112 corresponds to the first end 131 of the first conductive member 13 on its corresponding side. The two first holes 112 are closer to the centerline of the first housing 11 than the two first wiring holes 111. Each first hole 112 has a first unlocking member 15 that can be moved inward or outward along the first hole 112 under the action of external force. When the first unlocking member 15 moves inward, it pushes against the first end 131 of the first conductive member 13 on its corresponding side, causing it to deform towards the second end 132. This causes the first end 131 of the first conductive member 13 to no longer press against the wire 30, that is, to separate from the wire 30, so that the wire 30 can be easily pulled outward to disengage from the first wiring hole 111. It should be noted that when the wire 30 is inserted into the first wiring hole 111, the first unlocking member 15 may not be in contact with the first end 131 of the first conductive member 13, or it may be in contact but without applying a pushing force or the applied pushing force is insufficient to deform the first end 131. The magnitude of the pushing force by the first unlocking member 15 to deform the first end 131 of the first conductive member 13 is not described or limited; those skilled in the art can select it based on the material of the first conductive member 13, for example, 2.5 Nm. Furthermore, the degree of deformation is not described or limited, for example, 20% deformation. The first unlocking member 15 can be a nut or a push block with an elastic element (which applies a biasing force to the push block, causing it to move outwards from the first hole 112). Unlocking can be performed by using an unlocking tool such as a screwdriver to tighten the first unlocking member 15 or by pushing the first unlocking member 15 along the axial direction of the first hole 112. Preferably, in this embodiment of the invention, the two first unlocking members 15 of the two first holes 112 are connected together to form a single integral structure. This allows for the simultaneous unlocking and removal of the two wires 30 within the two first wiring holes 111 by pushing the two first unlocking members 15 to move synchronously in a single unlocking action. This improves the removal efficiency of the wires 30.
[0047] Similarly, such as Figure 4 As shown, the end of the second housing 21 furthest from the slot 22 is also as follows Figure 4 The right end shown is along the centerline of the second housing 21 on both sides, that is, as shown Figure 4The upper and lower sides are respectively provided with inwardly recessed second holes 212 extending along the centerline of the second housing 21. The extension direction of any second hole 212 intersects the third end 231 of the third conductive member 23 on its corresponding side. That is, the inner end of any second hole 212 corresponds to the third end 231 of the third conductive member 23 on its corresponding side. The two second holes 212 are closer to the centerline of the second housing 21 than the two second wiring holes 211. Similarly, a second unlocking member 25 is provided in any second hole 212, which can be moved inward or outward along the second hole 212 under the action of external force. When any second unlocking member 25 moves inward, it pushes against the third end 231 of the third conductive member 23 on its corresponding side to deform towards the fourth end 232, so that the third end 231 of the third conductive member 23 no longer presses against the wire 30, that is, it separates from the wire 30, so that the wire 30 can be easily pulled outward to disengage it from the second wiring hole 211. It should be noted that when the wire 30 is inserted into the second wiring hole 211, the second unlocking member 25 may not contact the third end 231 of the third conductive member 23, or it may contact it but without applying a pushing force or the applied pushing force is insufficient to deform the third end 231. The magnitude of the pushing force by the second unlocking member 25 to deform the third end 231 of the third conductive member 23 is not described or limited; those skilled in the art can select it based on the material of the third conductive member 23, for example, 2.5 Nm. Furthermore, the degree of deformation is not described or limited, for example, 20% deformation. The second unlocking member 25 can be a nut or a push block with an elastic element (which applies a biasing force to the push block, causing it to move outwards from the second hole 212). Unlocking tools such as screwdrivers can be used to tighten the second unlocking member 25 or along the axial direction of the second hole 212, i.e., as shown in the image. Figure 1 The unlocking operation is performed by pushing the second unlocking member 25 in the direction of the arrow shown. Preferably, in this embodiment of the invention, the two second unlocking members 25 of the two second holes 212 are connected together, forming a single integral structure. This allows for the simultaneous unlocking and removal of the two wires 30 within the two second wiring holes 211 by pushing the two second unlocking members 25 to move synchronously in a single unlocking action. This improves the removal efficiency of the wires 30.
[0048] like Figure 3 As shown, from the direction closest to to the second end 132, the first end 131 of any first conductive element 13 sequentially includes a first pushing section 1311 perpendicular to the axis of its corresponding first hole 112 and a first abutting section 1312 forming an angle (not specifically limited, but acute, exemplarily 15°) with the first pushing section 1311. The first abutting section 1312 extends in a direction away from its corresponding first wiring hole 111, i.e. Figure 2The first abutting section 1312 of the upper conductive member 13 extends obliquely upward to the right (to facilitate the insertion of the wire 30, guide it, and reduce the pushing force when the wire 30 is inserted) and abuts against the first limiting portion 144 of the corresponding second conductive member 14 when no wire 30 is inserted into the corresponding first wiring hole 111. When any of the first unlocking members 15 moves inward, it abuts against the first pushing section 1311 of the first end 131 of its corresponding first conductive member 13. Since the first unlocking member 15 moves along the axis of the first hole 112 to unlock, the first pushing section 1311 is positioned directly opposite the first hole 112, which facilitates pushing the first end 131 to unlock. The first abutting section 1312 is angled with the first pushing section 1311 and extends away from the first wiring hole 111. The first abutting section 1312 deforms more easily towards the second end 132 than the first pushing section 1311. When the first pushing section 1311 deforms inward under the pushing force, it will also cause the first abutting section 1312 to deform inward, thereby separating the first end 131 from the wire 30, thus facilitating the removal of the wire 30. Similarly, as... Figure 4 and Figure 5 As shown, from the direction closest to to the fourth end 232, the third end 231 of any third conductive element 23 sequentially includes a second pushing section 2311 perpendicular to the axis of its corresponding second hole 212 and a second abutting section 2312 forming an angle (not specifically limited, but acute, exemplarily 15°) with the second pushing section 2311. The second abutting section 2312 extends in a direction away from its corresponding second wiring hole 211, that is, as shown... Figure 4 The second abutting section 2312 of the upper third conductive member 23 extends obliquely to the upper left (to facilitate the insertion of the wire 30, guide it, and reduce the pushing force when the wire 30 is inserted) and abuts against the second limiting part 243 of the corresponding fourth conductive member 24 when the wire 30 is not inserted into the corresponding second wiring hole 211. When any second unlocking member 25 moves inward, it abuts against the second pushing section 2311 of the third end 231 of its corresponding third conductive member 23.
