Connectors usually include components such as terminals and socket sleeves. The terminals are fastened to the sleeves through assembly processes such as interlocking. The design of the terminals directly affects the current carrying capacity and stability of the circuit. The terminal's fastening technology mainly relies on the rebound effect of the side springs. When the terminal is not fully inserted into the socket, the springs are squeezed until the terminal is inserted into place, and the springs rebound against the fastening position in the socket, thereby fixing the terminal in the socket.

DETAILED DESCRIPTION

[0034] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] In order to solve the problems in the prior art that the terminal assembly force is large and the spring force is small, the assembly feel is poor and the terminal cannot be fixed in the socket, such as Figure 1 As shown, a connector for preventing spring sheet from being trapped is provided, comprising a socket body 1 and a terminal 2. A plurality of slots 3 are provided in the socket body 1, and the slots 3 match the shape of the terminal 2. Figure 2As shown, both sides of the lower end of the terminal 2 are provided with elastic limiting pieces 4, and the two elastic limiting pieces 4 are arranged on the terminal 2 in a relative manner. The lower end of the elastic limiting piece 4 is integrally formed with the terminal 2, and the upper end of the elastic limiting piece 4 expands outward. The lower end of the slot 3 is provided with a limiting groove 5. When the terminal 2 is inserted into the slot 3 of the socket body 1, the elastic limiting piece 4 abuts against the limiting groove 5. When the terminal 2 is not fully inserted into the slot 3, the elastic limiting piece 4 thereon is pressed against the inside of the slot 3 until the terminal 2 is inserted into place, and its elastic limiting piece 4 rebounds against the limiting groove 5 in the socket, thereby fixing the terminal 2 in the socket and improving the stability of the terminal 2.

[0037] like Figure 3 As shown, an opening is provided at the elastic limiting piece 4 on the terminal 2, and a stop piece 6 is provided at the opening of the terminal 2. The side of the stop piece 6 is integrally formed with the terminal 2, and four stop pieces 6 are provided. Two stop pieces 6 are located on the inner side of the elastic limiting piece 4 on one side, and two stop pieces 6 are located on the inner side of the elastic limiting piece 4 on the other side. The stop pieces 6 on both sides of the elastic limiting piece 4 widen the width of the lower end of the terminal 2. When the terminal 2 is not fully inserted into the slot 3, the elastic limiting piece 4 thereon is squeezed against the stop piece 6, and the stop piece 6 resists the elastic limiting piece 4, giving the elastic limiting piece 4 an outward expansion force, thereby preventing the problem of the spring sheet settling down and not rebounding when the terminal 2 is installed into the socket.

[0038] like Figure 4 As shown, the stop piece 6 is provided with a reinforcing rib 7, which extends from the stop piece 6 to the terminal 2. The terminal 2 is not fully inserted into the socket body 1, and the elastic limiting piece 4 is pressed against the reinforcing rib 7 of the stop piece 6. The reinforcing rib 7 is designed on the stop piece 6 to mainly increase the strength and rigidity of the stop piece 6. When the terminal 2 is installed, the spring piece is in an extruded state, and the reinforcing rib 7 plays a supporting role. After being extruded, the stop piece 6 will not be deformed, thereby ensuring the stability of the installation.

[0039] When the terminal 2 is not fully inserted into the socket body 1, the elastic limiting piece 4 partially or completely abuts against the stop piece 6. When the elastic limiting piece 4 is completely abutted against the stop piece 6, the width of the combination of the lower end of the terminal 2 and the stop pieces 6 on both sides thereof is set to be 1.1-1.2 mm, so that the elastic limiting piece 4 is flush with the upper end plane of the terminal 2, which can avoid the risk of the elastic limiting piece 4 hanging on the wall when the terminal 2 is installed in the socket body 1 in the extreme state.

[0040] The material of the terminal 2 is phosphor copper, and the thickness of the terminal 2 is 0.2mm. Phosphor copper is a material with high elasticity and high strength, which can support the elastic limiting piece 4 on the terminal 2 to abut against the socket body 1 and rebound in the socket body 1, thereby improving the stability of the terminal 2. The material of the socket body 1 is PA66, which has high mechanical strength and hardness, and great rigidity, so that the terminal 2 can be safely plugged into the socket body 1 without damaging the connector.

[0041] Example 2

[0042] In order to further prevent the elastic limiting sheet 4 from settling down, the present application Figure 5 and 6 As shown, a locking structure 8 is provided on the inner side of the elastic limiting sheet 4. The locking structure 8 includes a first locking sheet 801 and a second locking sheet 802, wherein the first locking sheet 801 is provided on the elastic limiting sheet 4 on one side, and the second locking sheet 802 is provided on the elastic limiting sheet 4 on the other side, wherein the upper ends of the first locking sheet 801 and the second locking sheet 802 are integrally formed with the elastic limiting sheet 4, and the lower ends of the first locking sheet 801 and the second locking sheet 802 are gathered inwardly.

[0043] When the terminal 2 is not fully inserted into the slot 3, the elastic limiting piece 4 on the terminal 2 is squeezed, and the first locking piece 801 and the second locking piece 802 on its inner side are abutted against each other, giving the elastic limiting piece 4 an outward expansion force, thereby preventing the problem of the spring sheet not rebounding when the terminal 2 is installed into the socket.

[0044] Example 3

[0045] In order to reduce the assembly force of terminal 2, as Figure 7-9 As shown, a locking belt 803 is provided at the lower ends of the first locking piece 801 and the second locking piece 802. The locking belt 803 is provided at the connection between the first locking piece 801 and the second locking piece 802, and the lower ends of the first locking piece 801 and the second locking piece 802 are connected by the locking belt 803. The locking belt 803 is a tearable toothed belt, and the locking belt 803 can unlock the first locking piece 801 and the second locking piece 802 when an external force is applied.

[0046] An elastic expansion structure 9 is also provided on the inner side of the elastic limiting piece 4, and the elastic expansion structure 9 is located below the locking belt 803. The elastic expansion structure 9 includes a first expansion piece 901 and a second expansion piece 902, wherein the first expansion piece 901 is provided on the elastic limiting piece 4 on one side, and the second expansion piece 902 is provided on the elastic limiting piece 4 on the other side. The lower ends of the first expansion piece 901 and the second expansion piece 902 are integrally formed with the elastic limiting piece 4, and the upper ends of the first expansion piece 901 and the second expansion piece 902 are butted against each other.

[0047] like Figure 8As shown, when the locking structure 8 is in the locked state, before the terminal 2 is inserted into the socket body 1, the first locking piece 801 and the second locking piece 802 gather the elastic limiting members on both sides, and the elastic limiting members on both sides of the terminal 2 gather inward under the influence of the locking structure 8. The elastic limiting members on the terminal 2 have an inward extrusion force, and when the terminal 2 is inserted into the socket body 1, the extrusion force can reduce the assembly force of the terminal 2 inserted into the socket body. The upper ends of the first expansion piece 901 and the second expansion piece 902 are bent and squeezed against each other, and have an outward expansion force.

[0048] When the terminal 2 is gradually inserted into the socket body 1, the first expansion piece 901 and the second expansion piece 902 extend upward, and the first locking piece 801 and the second locking piece 802 extend downward, thereby disassembling the locking belt 803 between the first locking piece 801 and the second locking piece 802. The elastic limiting members on both sides are not pulled by the first locking piece 801 and the second locking piece 802, and expand outwards naturally respectively, and the elastic limiting members are against the inner side of the slot 3.

[0049] like Fig. 9 As shown, the locking strip 803 is disconnected, the first locking piece 801 and the second locking piece 802 are separated, and at this time, the first expansion piece 901 and the second expansion piece 902 are no longer restricted by the locking structure 8, and release their outward expansion force until the terminal 2 rebounds against the limiting groove 5 in the socket body 1 by relying on its own elastic expansion force and the elastic expansion structure 9. At this time, the terminal 2 is completely inserted into the socket body 1.

[0050] The use process of the embodiment of the present invention is as follows:

[0051] Before the terminal 2 is inserted into the socket body 1, the elastic limiting piece on the terminal 2 has an inward extrusion force. When the terminal 2 is not fully inserted into the slot 3, the elastic limiting piece 4 thereon is pressed against the stop piece 6, and the stop piece 6 resists the elastic limiting piece 4, giving the elastic limiting piece 4 an outward expansion force. When the terminal 2 is gradually inserted into the socket body 1, the first expansion piece 901 and the second expansion piece 902 extend upward, thereby disassembling the locking belt 803 between the first locking piece 801 and the second locking piece 802, and the elastic limiting pieces on both sides are not pulled by the first locking piece 801 and the second locking piece 802, and expand outward naturally respectively, and the elastic limiting pieces are against the inner side of the slot 3. At this time, the first expansion piece 901 and the second expansion piece 902 are also not restricted by the locking structure 8, and release their outward expansion force until the terminal 2 relies on its own elastic expansion force and the elastic expansion structure 9 to rebound and press against the limiting groove 5 in the socket body 1. At this time, the terminal 2 is fully inserted into the socket body 1.

[0052] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
