Description
Technical Field
[0001] This application relates to the technical field of electrical connectors, and in particular to a through-hole power distribution terminal. Background Technology
[0002] Power connectors, as a type of conventional electrical connector, are mainly used for the transmission of current. Typically, after power connectors are installed and fixed with copper busbars, they suffer from problems such as lack of protection, short creepage distance, and low safety performance. They still require additional insulating brackets and acrylic glass for isolation and protection, which is not convenient in actual use. Improved power connectors usually include several or a single power terminal and an insulating base to support the power terminal and insulate the surrounding area.
[0003] Regarding the aforementioned technologies, the applicant believes that some current power connectors have unstable connections, are prone to loosening, poor contact, and other issues, and therefore still need improvement. Utility Model Content
[0004] To improve wiring stability, reduce loosening and poor contact, and enhance electrical connection stability, this application provides a direct-plug power distribution terminal.
[0005] The direct-plug power distribution terminal provided in this application adopts the following technical solution:
[0006] A plug-in power distribution terminal includes an insulating housing and an integral irregularly shaped conductor installed inside the insulating housing. A pin contact, inserted into the integral irregularly shaped conductor and connected to a power connection cable, is fixed inside the insulating housing by a conductive crown spring. The insulating housing has a locking structure for locking the pin contact. The locking structure includes a pull-out assist member movably connected inside the insulating housing and with its end extending outside the insulating housing. The pull-out assist member is located on one side of the pin contact, and its sidewall is spaced apart with movable slots that mate with the sidewall of the pin contact. When the pin contact is inserted into the integral irregularly shaped conductor, the sidewall of the pull-out assist member, offset from the movable slot, abuts against the pin contact.
[0007] By adopting the above technical solution, the movable push-pull component serves two purposes. First, when the pin contact is inserted into the integrated irregular conductive body, the push-pull component, with its sidewall offset from the movable slot, abuts against the pin contact to lock it in place. This improves the stability of the connection circuit, reduces loosening and poor contact, and enhances electrical connection stability. Second, the movable push-pull component allows the movable slot to align with the sidewall of the pin contact, facilitating easy removal of the pin contact and preventing damage caused by insertion and removal. The wear and tear of the terminals in this application helps extend service life. The terminals allow for tool-free connection of wires with pins, simplifying operation and saving insertion force. When inserting a wire with pins, the conductive crown spring contacts open and provide the necessary pressure to secure the conductor. To release or remove a wire with pins, simply move the pull-out aid; direct contact with live parts is unnecessary, making it safer. This connection method has undergone various tests and verifications; for example, its shock resistance meets railway standard EN50155, and its impact and corrosion resistance meet current classification society standards. Furthermore, it has passed verification in the increased safety zone (Exe) of the process control field.
[0008] Preferably, the locking structure further includes a spring located inside the insulating housing, with both ends of the spring abutting against the pull-out push-pull member and the corresponding part of the inner wall of the insulating housing, respectively.
[0009] By adopting the above technical solution, the springs that abut against the pull-out push-pull component and the insulating shell respectively realize the horizontal movement of the pull-out push-pull component relative to the insulating shell, so as to control the abutment locking of the pull-out push-pull component against the pin contact and the unlocking operation of the movable slot corresponding to the pin contact.
[0010] Preferably, an insulating cover is installed on one side of the insulating housing at the end of the pull-out push-pull component that passes through the insulating housing, and baffles that abut against both sides of the pull-out push-pull component are extended and fixed on the inner wall of the insulating cover; the insulating cover is snapped onto the insulating housing by a snap-fit structure.
[0011] By adopting the above technical solution, the insulating cover and baffle can assist in the positioning of the push-pull component, and the snap-fit structure enables the insulating cover to be detachably connected to the insulating shell, which facilitates the installation of the push-pull component and the spring and reduces the assembly difficulty.
[0012] Preferably, the snap-fit structure includes a snap-fit block and a snap-fit groove. The snap-fit block is fixed to the side wall of the insulating cover, and the snap-fit groove is formed on the corresponding side wall of the insulating housing. The snap-fit block can be deformed and snapped into the snap-fit groove. The snap-fit block has a guide slope on the side wall facing the insulating housing, and the side wall of the insulating housing and the side of the snap-fit groove has a guide groove that matches the guide slope.
[0013] By adopting the above technical solution, the insulating cover can be conveniently installed on the insulating shell through the cooperation of the snap-fit block and the snap-fit groove; under the guidance of the guide slope and the guide groove, the snap-fit block deforms smoothly and snaps into the snap-fit groove, making the assembly operation more convenient.
[0014] Preferably, an abutment plate extends from the pull-out member, a sleeve post is fixed on the inner wall of the insulating cover, one end of the spring is sleeved on the sleeve post and abuts against the inner wall of the insulating cover, and the other end abuts against the abutment plate.
[0015] By adopting the above technical solution, the extension of the abutment plate is used to provide a support point for the spring, and the sleeve post improves the installation and movement stability of the spring.
[0016] Preferably, the end of the pull-out push-pull component that passes through the insulating housing has a handle portion; the handle portion includes an insert handle and a handle cover; the insert handle is installed on one side of the pull-out push-pull component, and the handle cover is fixed to the insert handle by a cover structure and located on the other side of the pull-out push-pull component; the insert handle and the handle cover are fitted together to form a number of anti-slip stripes.
[0017] By adopting the above technical solution, the insert handle and handle cover are installed on the pull-out push-pull component, making assembly convenient; the anti-slip stripes increase the friction of the hand grip, making it easier to drive the pull-out push-pull component to slide.
[0018] Preferably, the insert handle has a limiting plate whose shape matches the side wall of the pull-out push-pull component and positions the pull-out push-pull component. The cover structure includes a positioning sleeve, a locking sleeve, and positioning posts. The positioning sleeve is fixed inside the limiting plate, and the pull-out push-pull component has a mating groove for the positioning sleeve to be inserted. The locking sleeve is formed on the outside of the limiting plate, and the positioning posts are fixed at intervals on the handle cover and respectively snapped into the corresponding positioning sleeve and locking sleeve.
[0019] By adopting the above technical solution, the positioning sleeve, locking sleeve and corresponding positioning post are respectively engaged to fix the push-pull auxiliary component between the insert handle and the handle cover, and to achieve mutual fixation between the insert handle and the handle cover, thereby reducing the difficulty of the assembly process.
[0020] Preferably, a connecting plate with mounting holes extends from the integral irregular conductive body and passes through the insulating shell, wherein the angle of the connecting plate is one of 30°, 90° or 180°.
[0021] By adopting the above technical solution, the connecting plate on the integrated irregular conductor for connecting to electrical equipment such as circuit breakers can be set to one of 30°, 90° or 180°, so as to adapt to the installation requirements of different positions.
[0022] Preferably, at least two power distribution sockets are formed on the integrated irregular conductor, and a power socket corresponding to the power distribution socket is formed on the upper part of the insulating shell, and the pin contact is inserted into the corresponding power socket and power distribution socket.
[0023] By adopting the above technical solution, at least two power distribution sockets are provided on the integrated irregular conductor. The number of power distribution sockets can be increased as needed to match the number of wiring holes required for current transmission. The power sockets and power distribution sockets correspond to each other for the corresponding insertion of pin contacts.
[0024] Preferably, a support seat for supporting the push-pull member is fixed inside the insulating shell, and a through groove for accommodating the abutment plate and the spring is provided on the support seat; support seats for supporting the integrated irregular conductive body are fixed on both sides inside the insulating shell, and the upper surface of the support seat is higher than the support seat.
[0025] By adopting the above technical solution, the support base supports the integrated irregular conductor, and the support base is lower than the support base, so that the push-pull auxiliary component can be inserted into the gap between the integrated irregular conductor and the support base; the through groove provides accommodation and movement space for the abutment plate and spring, and the overall structure is more reasonable.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] When the pin contact is inserted into the integrated irregular conductive body, the side wall of the push-pull aid, which is offset from the movable slot, abuts against the pin contact to lock it, thereby improving the stability of the connection line, reducing loosening and poor contact, and improving the stability of the electrical connection. When the movable slot corresponds to the side wall of the pin contact, the pin contact can be easily pulled out, which can also reduce component wear and extend service life. The terminal of this application can easily complete the connection of wires with pins without any tools, which is simple to operate and saves insertion force. If you want to loosen and pull out the power connection cable with pins, you only need to use the push-pull aid, without direct contact with live parts, making it safer to use.
[0028] The horizontal movement of the push-pull member relative to the insulating shell is achieved by springs that abut against the push-pull member and the insulating shell respectively, so as to control the abutment locking of the push-pull member against the pin contact and the unlocking operation of the movable slot corresponding to the pin contact.
[0029] The connecting plate on the integrated irregular conductor for connecting to electrical equipment such as circuit breakers can be set to 30°, 90° or 180° to adapt to the installation requirements of different positions;
[0030] The insulating housing is provided with at least two power distribution sockets, and the number of power distribution sockets can be increased as needed to match the number of wiring holes required for current transmission; the interconnection between power distribution sockets can further improve stability.
[0031] The snap-fit structure, which uses snap-fit blocks and snap-fit slots, enables the detachable connection of the insulating cover to the insulating housing, facilitating the installation of the pull-out push-pull component and the spring. The insert handle and handle cover are installed on the pull-out push-pull component through a cover-fitting structure that uses a positioning sleeve, a locking sleeve, and a corresponding positioning post to snap together, reducing the overall assembly difficulty of the power connector.

[0046] The present application will be further described in detail below with reference to the accompanying drawings.
[0047] This application discloses a through-hole power distribution terminal, referring to... Figure 1 It includes an insulating housing 1 and an integral irregularly shaped conductor 2 installed inside the insulating housing 1. Support seats 1-1 supporting the integral irregularly shaped conductor 2 are fixed on both sides inside the insulating housing 1. At least two power distribution sockets 2-1 are formed on the integral irregularly shaped conductor 2 as output terminals.
[0048] Reference Figure 1 The upper part of the insulating shell 1 forms a power socket 1-2 corresponding to the power distribution socket 2-1. Each power socket 1-2 is provided with a conductive crown spring 3, and a pin contact 4 connected to a power connection cable with pins is fixedly inserted into the power socket 1-2 through the conductive crown spring 3. The pin contact 4 is installed in the corresponding power distribution socket 1-2. The conductive crown spring 3 ensures the conductivity of the power distribution socket 2-1 and the power connection cable with pins, and prevents it from getting hot.
[0049] Reference Figure 1 One side of the integral irregular conductor 2 extends to form a connecting plate 2-2 with a mounting hole. The connecting plate 2-2 passes through the outside of the insulating housing 1 and is set horizontally at 180° for installation on the required electrical equipment.
[0050] Reference Figure 1 , 2The insulating housing 1 is provided with a locking structure 5 for locking the pin contact 4. The locking structure 5 includes a pull-out push-pull member 5-1. The middle part of the insulating housing 1 is fixed between the opposite support seats 1-1 and a support seat 1-3 for supporting the pull-out push-pull member 5-1. The upper surface of the support seat 1-1 is higher than the support seat 1-3, so that the pull-out push-pull member 5-1 can be inserted into the gap between the integrated irregular conductor 2 and the support seat 1-3. The pull-out push-pull member 5-1 is movably connected to the insulating housing 1 and its end extends through the outside of the end of the insulating housing 1 away from the connecting plate 2-2.
[0051] Reference Figure 2 The pull-out push-pull component 5-1 is located on one side of the pin contact component 4. The side wall of the pull-out push-pull component 5-1 is provided with movable slots 5-1-1 that cooperate with the side wall of the pin contact component 4. When the pin contact component 4 is inserted into the integrated irregular conductive body 2, the side wall of the pull-out push-pull component 5-1, which is offset from the movable slot 5-1-1, abuts against the pin contact component 4, thereby locking the pin contact component 4, improving the stability of the connection line, reducing loosening and poor contact, and improving the stability of the electrical connection.
[0052] Reference Figure 2 , 3 An insulating cover 1-4 is installed on one side of the insulating housing 1 at the end of the push-pull member 5-1 that passes through the insulating housing 1. The locking structure 5 also includes a spring 5-2 located inside the insulating housing 1. The push-pull member 5-1 extends downward to form an abutment plate 5-1-2. A sleeve post 1-4-1 is fixed on the inner wall of the insulating cover 1-4. One end of the spring 5-2 is sleeved on the sleeve post 1-4-1 and abuts against the inner wall of the insulating cover 1-4, and the other end abuts against the abutment plate 5-1-2. The abutment plate 5-1-2 provides a support point for the spring 5-2, and the sleeve post 1-4-1 improves the installation and movement stability of the spring 5-2. When the spring 5-2 extends naturally, the side wall of the push-pull member 5-1, which is offset from the movable slot 5-1-1, abuts against the pin contact member 4.
[0053] Reference Figure 2 , 3 The support seat 1-3 has a through groove 1-3-1 for accommodating the abutment plate 5-1-2 and the spring 5-2, providing accommodating and movable space for the abutment plate 5-1-2 and the spring 5-2, making the overall structure more reasonable.
[0054] Reference Figure 1 , 4The insulating cover 1-4 is snapped onto the insulating housing 1 via a snap-fit structure 6. The snap-fit structure 6 includes a snap-fit block 6-1 and a snap-fit groove 6-2. Two adjacent snap-fit blocks 6-1 are fixed to the upper and lower side walls of the insulating cover 1-4, respectively. The snap-fit groove 6-2 is correspondingly opened on the upper and lower side walls of the insulating housing 1. The snap-fit block 6-1 can deform and snap into the snap-fit groove 6-2. A guide slope 6-1-1 is formed on the side wall of the snap-fit block 6-1 facing the insulating housing 1. A guide groove 1-5 that cooperates with the guide slope 6-1-1 is opened on the side wall of the insulating housing 1 located on the side of the snap-fit groove 6-2. Under the guidance of the guide slope 6-1-1 and the guide groove 1-5, the snap-fit block 6-1 deforms smoothly and snaps into the snap-fit groove 6-2, making the assembly operation more convenient.
[0055] Reference Figure 3 , 4 The inner wall of the insulating cover 1-4 is extended and fixed with baffles 1-4-2 that abut against both sides of the pull-out push-pull component 5-1, which serve to position the pull-out push-pull component 5-1.
[0056] Reference Figure 3 , 5 An insulated handle portion 7 is provided at the end of the push-pull assist component 5-1 that passes through the insulating housing 1. The handle portion 7 includes a blade handle 7-1 and a handle cover 7-2. The blade handle 7-1 is installed above the push-pull assist component 5-1, and the handle cover 7-2 is fixed to the blade handle 7-1 by a cover structure 9 and is located below the push-pull assist component 5-1. Several anti-slip stripes 8 are formed on the outer walls of the blade handle 7-1 and the handle cover 7-2 to increase the friction of the hand grip and make it easier to drive the push-pull assist component 5-1 to slide.
[0057] Reference Figure 3 , 5 The insert handle 7-1 has a limiting plate 7-1-1 whose shape matches the side wall of the pull-pull push-pull member 5-1 and positions the pull-pull push-pull member 5-1. The cover structure 9 includes a positioning sleeve 9-1, a locking sleeve 9-2 and a positioning post 9-3.
[0058] Reference Figure 2 , 5 The positioning sleeve 9-1 is fixed inside the limiting plate 7-1-1, and the pull-pull aid 5-1 has a mating groove 5-1-3 for the positioning sleeve 9-1 to be inserted.
[0059] Reference Figure 3 , 5The locking sleeve 9-2 is formed on the outside of the limiting plate 7-1-1. The positioning pins 9-3 are fixed at intervals on the handle cover 7-2 and respectively snapped into the corresponding positioning sleeves 9-1 and locking sleeves 9-2. This serves to fix the push-pull auxiliary component 5-1 between the insert handle 7-1 and the handle cover 7-2, and to achieve mutual fixation between the insert handle 7-1 and the handle cover 7-2, thereby reducing the difficulty of the assembly process.
[0060] The assembly and operation process of this application is as follows: First, the conductive crown spring 3 is installed into the integrated irregular conductive body 2. Then, the integrated irregular conductive body 2 is installed into the insulating housing 1 from the back. Next, the pull-out push-pull component 5-1 is inserted into the insulating housing 1. Then, the spring 5-2 is placed in. Next, the insulating cover 1-4 is snapped into the insulating housing 1. Finally, the insert handle 7-1 is first put on the pull-out push-pull component 5-1. Then, the handle cover 7-2 is pressed into the insert handle 7-1 from bottom to top.
[0061] When installing the pin contact 4, hold the insert handle 7-1 and handle cover 7-2 and pull them outwards from the insulating housing 1. At this time, the spring 5-2 is compressed, and the movable slot 5-1-1 on the pull-out push-pull member 5-1 engages with the side wall of the pin contact 4. The pin contact 4 is inserted into the power distribution socket 1-2 and fixed by the conductive crown spring 3. Then release the hand. Under the restoring force of the spring 5-2, the pull-out push-pull member 5-1 moves inwards from the insulating housing 1. The movable slot 5-1-1 is misaligned with the pin contact 4. The side wall of the pull-out push-pull member 5-1, which is misaligned with the movable slot 5-1-1, abuts against the pin contact 4 and locks the pin contact 4. Example
[0062] The difference from Example 1 is that, as Figure 6 As shown, the power distribution sockets 1-2 on the same side are interconnected, which can further improve the structural stability.
[0063] In addition, the power distribution sockets 1-2 on opposite sides can be further fixed to each other to improve structural stability. Example
[0064] The difference from Example 1 is that, as Figure 7 As shown, the angle of the connecting plate 2-2 is 30° to accommodate the installation requirements of electrical equipment in different locations. Example
[0065] The difference from Example 1 is that, as Figure 8 As shown, the angle of the connecting plate 2-2 is 90° to accommodate the installation requirements of electrical equipment in different locations.
[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
