[0019] See also Figure 1 , 2 , 3, 4, 5, and 6 are schematic diagrams of preferred embodiments of the present invention. The present invention relates to a line-to-line connector that can achieve rapid connection and disconnection, comprising: a first insulating seat 1, a plurality of first terminals 2, a second insulating seat 3, and a plurality of second terminals 4, wherein the first insulating seat 1 and the plurality of first terminals 2 are fixedly connected together to form a rotating assembly, and the second insulating seat 3 and the plurality of second terminals 4 are fixedly connected together to form another rotating assembly, and then the two rotating assemblies are assembled together to form a line-to-line connector that can achieve rapid connection and disconnection.
[0020] The first insulating seat 1 is an injection molded part, and the first insulating seat 1 has at least a first splicing portion 11 and a first wiring portion 12, and a first overlap surface 111 is provided on the first splicing portion 11, and a pair of clamping arms 13 protruding forward are provided at the front end of the first splicing portion 11; a plurality of first terminals 2 are injection molded together with the first insulating seat 1, and the first terminal 2 has a first contact portion 21 extending to the first splicing portion 11 and exposed upward from the first overlap surface 111, and a first welding leg 22 extending to the first wiring portion 12; the first contact portion 21 is used for electrical contact connection, and the first welding leg 22 is used for welding connection with the corresponding wire. In actual use, after the first welding leg 22 is welded and connected with the corresponding wire, it is not ruled out that a protective cover is added to the first wiring portion 12 or a protective layer is injected to protect the welding part and increase the service life.
[0021] The second insulating seat 3 is an injection molded part, and the second insulating seat 3 has at least a second splicing portion 31 and a second wiring portion 32, and a second overlap surface 311 is provided on the second splicing portion 31; a plurality of second terminals 4 are injection molded together with the second insulating seat 3, and the second terminal 4 has a second contact portion 41 extending to the second splicing portion 31 and exposed upward from the second overlap surface 311, and a second welding foot 42 extending to the second wiring portion 32; similarly, the second contact portion 41 is used for electrical contact connection, and the second welding foot 42 is used for welding connection with the corresponding wire. In actual use, after the second welding foot 42 is welded and connected with the corresponding wire, it is not ruled out that a protective cover is added to the second wiring portion 32 or a protective layer is injected to protect the welding part and increase the service life.
[0022] The second joint portion 31 of the second insulating seat 3 is embedded between the pair of clamp arms 13 and connected to the pair of clamp arms 13 by a hinge, so that the second insulating seat 3 and the first insulating seat 1 can rotate relative to each other, and the first overlap surface 111 and the second overlap surface 311 can be overlapped or separated. Figure 1 The figure shows the first overlapping surface 111 and the second overlapping surface 311 in a lapping state; Figure 2 The figure shows the separation of the first overlap surface 111 and the second overlap surface 311. When the first overlap surface 111 and the second overlap surface 311 are overlapped, an anti-slip structure is introduced to ensure that the first overlap surface 111 and the second overlap surface 311 are in a stable overlapped state, so that the first contact portion 21 of the first terminal 2 and the second contact portion 41 of the second terminal 4 maintain a contact connection posture, and obtain an electrical conduction transmission relationship between the first terminal 2 and the second terminal 4, that is, to achieve line-to-line connection conduction.
[0023] Figure 1 , 2As shown, the anti-slip structure described in this embodiment includes an elastic side fence 14 arranged on the left and right sides of the first overlap surface 111 and protruding upward, and a stopper 141 is provided on the elastic side fence; the elastic side fence 14 is pressed against the side of the second splicing part 31, and the stopper 141 cooperates with the preset buckle 312 on the side of the second splicing part 31 to establish an anti-slip state. Further, the elastic side fence 14 is a plate body made integrally with the first insulating seat 1, with good structural properties and easy to make. The stopper 141 is an opening on the elastic side fence 14, and the preset buckle 312 on the side of the second splicing part 31 is a convex point, and the stopper 141 uses the elasticity of the elastic side fence 14 to adapt to the buckle 312. The design of the anti-slip structure can effectively prevent the connector from automatically disconnecting in a vibration environment, and the elasticity of the elastic side fence 14 can be used to facilitate the connection or separation of the stopper 141 and the buckle 312. The second insulating seat 3 and the first insulating seat 1 can rotate relative to each other, so that when the first overlapping surface 111 and the second overlapping surface 311 are overlapped, the buckle 312 squeezes the elastic side fence 14 and snaps into the stopper 141. When it is necessary to disengage, the stopper 141 and the buckle 312 can be separated by breaking the elastic side fence 14. At this time, the second insulating seat 3 or the first insulating seat 1 can be rotated, the first overlapping surface 111 and the second overlapping surface 311 are separated, and the first terminal 2 and the second terminal 4 are disconnected. The elastic side fence 14 is designed to be bilaterally symmetrical, and is squeezed against the side of the second splicing part 31 to effectively provide limiting and guiding, ensuring the stability and accuracy of the overlapping of the first overlapping surface 111 and the second overlapping surface 311, so that the first contact part 21 of the first terminal 2 and the second contact part 41 of the second terminal 4 are accurately contacted and connected.
[0024] In this embodiment, the first insulating seat 1 is flat, and the first splicing portion 11 and the first wiring portion 12 extend in opposite directions on the same plane. They are small in size and have a corresponding length to facilitate subsequent turning and rotation. The upper plane of the first wiring portion 12 is separated from the first lap surface 111 by a raised first partition wall 15. The first partition wall 15 is made integrally with the first insulating seat 1, has good structural properties, and is easy to make. The first partition wall 15 not only serves as a partition to prevent the welding process from affecting the first contact portion 21 of the first terminal 2, but also increases the structural properties of the first insulating seat 1 and the assembly stability of the first terminal 2. The top of the first partition wall 15 is provided with a first hand-held inclined surface 151 inclined toward the first wiring portion 12, which is convenient for hand-held operation and improves the operability and comfort of rapid connection and disconnection.
[0025] Figure 2 , 3As shown in Figures 4 and 5, the first splicing portion 11 of this embodiment is provided with an avoidance groove 112 which is recessed downward from the first lap joint surface 111. The first contact portion 21 of the first terminal 2 is correspondingly embedded in the avoidance groove 112 and is cantilevered. The first contact portion 21 has an arched portion 211 which is arched upward and exposed from the first lap joint surface 111. This structure facilitates the first contact portion 21 to press and contact, and provides elastic buffering, is not prone to fatigue, improves durability in use, and ensures contact and conductive connection. Furthermore, the avoidance groove 112 runs through the upper and lower sides of the first splicing portion 11. The avoidance groove 112 not only provides an avoidance space, but also helps to dissipate heat and remove impurities, thereby ensuring the implementation of electrical connection.
[0026] In this embodiment, the second insulating seat 3 is flat, and the second splicing portion 31 and the second wiring portion 32 extend in opposite directions on the same plane. They are small in size and have a corresponding length to facilitate subsequent turning and rotation. The upper plane of the second wiring portion 32 is separated from the second lap surface 311 by a raised second partition wall 33. The second partition wall 33 is provided with a supporting top surface 331 on the side facing the second lap surface 311. The supporting top surface 331 supports the first splicing portion 11 to limit the rotation range of the second insulating seat 3 relative to the first insulating seat 1, so that the second insulating seat 3 can achieve the first lap surface 111 and the second lap surface 311 to fit or separate through relative positive and negative rotation. In this embodiment, when the first lap surface 111 is separated from the second lap surface 311, the supporting top surface 331 of the second partition wall 33 contacts the lower side of the supporting first splicing portion 11, thereby limiting the rotation of the second insulating seat 3 relative to the first insulating seat 1, preventing excessive rotation, and facilitating rapid conduction and disconnection operations. The second partition wall 33 is made integrally with the second insulating seat 3, has good structural properties, and is easy to make. The second partition wall 33 not only serves as a partition to prevent the welding process from affecting the second contact portion 41 of the second terminal 4, but also increases the structural properties of the second insulating seat 3 and the assembly stability of the second terminal 4; and the top of the second partition wall 33 is provided with a second hand-held inclined surface 332 inclined toward the second wiring portion 32, which is convenient for hand-held operation and improves the operability and comfort of rapid connection and disconnection.
[0027] In this embodiment, the second terminal 4 is a stamped terminal, and a contact protrusion 411 formed by stamping is provided on the second contact portion 41, and a corresponding glue-eating concave position 412 is formed on the back of the contact protrusion 411. The contact protrusion 411 protrudes from the second overlapping surface 311, which is conducive to the overlapping and conductive connection between the second contact portion 41 and the first contact portion 21. The glue-eating concave position 412 increases the amount of glue, so that the second terminal 4 and the second insulating seat 3 are more firmly combined, the assembly structure is improved, and the electrical connection is ensured.
[0028] Figure 1 , 2As shown in Figures 3, 4, and 5, in this embodiment, the clamp arm 13 is L-shaped and is made integrally with the first insulating seat 1, with good structural properties, easy to make, and small in size. A hinge hole 131 is provided in the vertical portion, and the hinge hole 131 cooperates with the external protruding pin shaft 313 preset on the corresponding side of the second splicing portion 31 to construct a hinge connection that can rotate relative to each other. During assembly, the second splicing portion 31 is squeezed and embedded between the pair of clamp arms 13, and the external protruding pin shaft 313 is inserted into the hinge hole 131, so that the second insulating seat 3 and the first insulating seat 1 can be connected and can rotate relative to each other, and are not easy to separate, have a simple structure, and are convenient for assembly and implementation.
[0029] The present invention enables the first insulating seat and the second insulating seat to rotate relative to each other, and satisfies the first overlap surface and the second overlap surface to overlap or separate, and introduces an anti-slip structure when the first overlap surface and the second overlap surface overlap, so that the first overlap surface and the second overlap surface obtain a stable overlap shape, so that the first contact portion of the first terminal and the second contact portion of the second terminal maintain a contact connection posture, and obtain an electrical conduction transmission relationship between the first terminal and the second terminal. The structure is simple and reasonable, and the first terminal and the second terminal can be quickly connected and disconnected. The first insulating seat is provided with a pair of clamping arms, and the second splicing portion of the second insulating seat is embedded between the pair of clamping arms and connected to the pair of clamping arms by a hinge, so that when the first terminal and the second terminal are disconnected, the first insulating seat and the second insulating seat do not separate, which is conducive to the next connection and improves the convenience of use.
[0030] Although the preferred specific embodiments of the present invention are described above in conjunction with the accompanying drawings, the present invention should not be limited to the structures and operations that are exactly the same as the above descriptions and drawings. For those skilled in the art, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and changes should all fall within the scope of protection required by the present invention.
