Description

Technical Field

[0001] The utility model relates to an electric connector. Background Art

[0002] Electrical connectors are common components in lighting, electronics, and communications engineering. Their function is to connect blocked or isolated circuits within a circuit, energize the circuit, and thus achieve the intended function.

[0003] The Chinese utility model patent "An Electrical Connector" with authorization announcement number CN210123828U (application number 201921329944.8) discloses an electrical connector for achieving coupling connection between two connectors. The electrical connector includes a first connector and a second connector. The first connector is provided with a first terminal, and the second connector is provided with a second terminal. The second terminal has a first contact end for connecting to the second terminal, and the second terminal has a second contact end for connecting to the first terminal. When the first connector and the second connector are plugged and connected, the first and second contact ends on the first and second terminals can be brought into contact and connected, thereby achieving conduction between the two wires. In order to connect the first and second connectors and prevent the first and second connectors from accidentally slipping off, the first connector and the second connector are provided with a first buckle body and a second buckle body that can be buckled with each other. The first buckle body is a hook, and the second buckle body is a horizontally arranged buckle ring for the hook portion of the hook to buckle into. The buckle ring and the hook need to have a certain degree of deformation so that the two can be buckled and separated. The hook and / or the buckle can also be rotatably connected to the first and second connectors, and the two can be fastened or separated by rotating the hook and / or the buckle. Problems with this electrical connector are: 1. The first contact end and the second contact end are mating concave-convex structures, which easily cause greater fastening resistance when the first and second connectors are connected, increasing the difficulty of the fastening operation. Moreover, after the first connector is plugged and connected to the second connector, the first and second contact ends are in a contact connection relationship. On the one hand, the contact area is very limited. On the other hand, it is easy for the first and second contact ends to deform due to long-term use, resulting in poor contact or even inability to release. 2. The first buckle body and the second buckle body adopt the structure of a hook and a buckle, which requires a large amount of deformation and is prone to breakage. Utility Model Content

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 4 As shown, the electrical connector in this embodiment includes a first connector 1 and a second connector 2 that can be snapped together. The first connector 1 and the second connector 2 are both provided with a wiring cavity 100 for installing wiring terminals and connecting wires. The wiring cavity of the first connector 1 is provided with at least one first wiring terminal 3, and the wiring cavity of the second connector 2 is provided with at least one second wiring terminal 4. The number of first wiring terminals 3 and second wiring terminals 4 is equal and their number is specifically set according to needs. The first wiring terminal 3 and the second wiring terminal 4 are both used to connect external wires. The first connector 1 and the second connector 2 are made of insulating material, and the first wiring terminal 3 and the second wiring terminal 4 are made of conductive metal material. During use, when the first connector 1 and the second connector 2 are snapped together, the first wiring terminal 3 and the second wiring terminal 4 are matched and connected, thereby realizing an electrical connection between the first wiring terminal 3 and the second wiring terminal 4, and correspondingly realizing an electrical conductive connection between the two terminals.

[0025] The first connector 1 and the second connector 2 are configured as required. In this embodiment, the first connector 1 and the second connector 2 are configured as a shell connector in the shape of a rectangular parallelepiped. For ease of description, the ends of the two connectors that are used for mating are referred to as the inner end, and the other ends are referred to as the outer end. The first connector 1 and the second connector 2 are provided with a snap-fitting snap-fit ​​assembly 7, so that the first connector 1 and the second connector 2 are connected to each other through the snap-fit ​​assembly 7, thereby ensuring the reliability of the connection between the first connector 1 and the second connector 2. At the same time, the snap-fit ​​assembly 7 can also be disassembled. In order to reduce the deformation of the snap-fit ​​assembly 7, improve the long-term life of the snap-fit ​​assembly 7, and reduce the pressing time, the snap-fit ​​assembly 7 includes a hook 71 provided on one of the first connector 1 and the second connector 2, and a buckle 72 provided on the other of the first connector 1 and the second connector 2. The buckle 72 is vertically arranged, that is, the socket formed by the buckle 72 is in the vertical direction, which is more convenient for the hook 71 to be inserted. In addition, a cavity 721 is formed on the connector where the buckle 72 is provided, and the buckle 72 is disposed in the cavity 721. In this embodiment, the thickness of the buckle 72 is relatively small, and the height of the hook portion of the hook 71 is only slightly higher than the buckle 72. The cavity 721 provides space for the deformation of the hook 71. During operation, the hook 71 only needs to be pressed to cause a small deformation to disengage from the buckle 72, thereby relatively disassembling the first connector 1 and the second connector 2. This makes the operation faster and more convenient, and can effectively extend the service life of the fastening assembly 7. In addition, the structure of the cavity 721 can ensure the smoothness of the two connectors after they are aligned.

[0026] In order to quickly achieve wiring, the first wiring terminal 3 includes a frame-shaped first base 32 and a first wiring spring 33 for pressing the wire. The first base 32 extends a tubular connecting tube 31 toward the inner end of the first connector 1. The connecting tube 31, the first base 32, and the first wiring spring 33 are all conductive metal parts. The first wiring spring 33 can adopt an elastic structure of any shape. In this embodiment, the first wiring spring 33 is V-shaped. The first wiring spring 33 is fixed to the first base 32 and is pressed against the inner wall of the first base 32. Specifically, the first end of the first wiring spring 33 is fixed to the lower inner wall of the first base 32, and the second end is pressed against the upper inner wall of the first base 32. When the external wiring is inserted, it is inserted between the second end of the first wiring spring 33 and the upper inner wall of the first base 32, and a fixed connection is achieved based on the spring force of the first wiring spring 33.

[0027] The wiring cavity 100 within the first connector 1 includes a mounting cavity 101 that matches the frame-shaped volume of the first base 32. A wire passage cavity 102 is provided at the outer end of the first connector 1, connecting to the mounting cavity 101. Thus, the mounting cavity 101 and the wire passage cavity 102 together constitute the wiring cavity 100. To ensure that the inserted wire can be secured by the first wiring spring 33, the wire passage cavity is located between the second end of the first wiring spring 33 and the upper inner wall of the first base 32.

[0028] The structure of the second terminal block 4 is essentially the same as that of the first terminal block 3. The installation structure of the second terminal block 4 within the second connector 2 is also the same as the installation structure of the first terminal block 3 within the first connector 1. Specifically, the second terminal block 4 includes a frame-shaped second base 42 and a second wiring spring 43 for pressing the wires. The second wiring spring 43 is fixed to the second base 42 and springs against the inner wall of the second base 42. The structure of the second wiring spring 43 and its connection method on the second base 42 are the same as the structure of the first wiring spring 33 and its connection method on the first base 32. The only difference is that a columnar connecting post 41 extends inward from the second base 42. The connecting post 41, the second base 42, and the second wiring spring 43 are all conductive metal parts.

[0029] When the first connector 1 and the second connector 2 are buckled together, the connecting post 41 is inserted into the connecting tube 31 to achieve electrical connection between the first connecting terminal and the second connecting terminal 4 .

[0030] The structure of the connecting column 41 and the connecting tube 31 is adopted, and the connection between the two terminals is achieved by plugging. This not only ensures the reliability of the connection between the two terminals and improves the stability of the electrical connection between the two, but also greatly increases the connection area between the two terminals, which can meet the needs of high-power electrical connection.

[0031] To facilitate insertion of the connecting column 41 into the connecting tube 31 and avoid difficulties caused by air pressure, the connecting tube 31 is provided with notches 311. The shape and number of notches 311 are determined as needed. In this embodiment, to reduce production complexity, the connecting tube 31 includes two opposed blades 312. The blades 312 have an arcuate cross-section, and the gap between the two blades 312 forms the notches 311. Together, the two curved blades 312 form the tubular structure of the connecting tube 31.

[0032] To protect the connecting tubes 31 and connecting posts 41 and to guide their connection, a protective sleeve 11 is provided on the snap-fit ​​end of the first connector 1, corresponding to each connecting tube 31. A guide hole 21, opening toward the snap-fit ​​end and corresponding to each connecting post 41, is provided in the second connector 2. The connecting post 41 extends within the guide hole 21.

[0033] When the first connector 1 and the second connector 2 are fastened together, the protective sleeve 11 is inserted into the guide hole 21. The cooperation between the guide hole 21 and the protective sleeve 11 guides the connection between the connecting tube 31 and the connecting post 41, allowing the connecting post 41 to be precisely inserted into the connecting tube 31, ensuring a reliable connection between the two. To further limit the stability of the insertion direction, a ridge 111 is provided on the protective sleeve 11 along the insertion direction, and a corresponding guide groove 211 is formed in the wire hole 21 to accommodate the ridge 111. The ridge 111 and the guide groove 211 limit the insertion direction, ensuring stability and accuracy.

[0034] In this embodiment, the length of the protective sleeve 11 is longer than the length of the connecting tube 31 , and the length of the guide hole 21 is longer than the length of the connecting column 41 , which can effectively ensure safety in use.

[0035] To facilitate wire removal, a first wire-removing member 5 is slidably disposed within the wire-passing cavity 102 of the first connector 1, pushing the first connection spring 33 in the opposite direction of the spring pressure. A second wire-removing member 6 is slidably disposed within the wire-passing cavity 102 of the second connector 2, pushing the second connection spring 43 in the opposite direction of the spring pressure. To remove the wires from the first and second connectors 1 and 2, the corresponding wire-removing member is pressed toward the inner ends of the connectors. As the wire-removing member moves inward, the connection spring retracts and deforms, releasing the spring pressure on the wire, allowing the wire to be removed from the connectors.
