[0030] The electric connector can be applied to scenes such as 3C electronic products, vehicle-mounted terminals, robots, etc. to realize transmission of current or signals between two electrical modules. In the related art, the electric connector for the circuit board needs to open the cover of the electric connector when being inserted into the circuit board, and then press the cover to fix the circuit board after being inserted into the circuit board. And some electric connectors do not allow the cover to be empty before being inserted into the circuit board, so as to avoid causing the terminal to be deformed. Therefore, the existing electric connector has problems of complicated operation, insufficient stability and being not conducive to assembly during use.

[0031] The present disclosure provides an electric connector. Figure 1 is a partial structure schematic view of a cover of an electric connector in a buckled state in an exemplary embodiment of the present disclosure, Figure 2 is a structure schematic view of a cover of an electric connector in an open state in an exemplary embodiment of the present disclosure, Figure 3 is a structure schematic view of an electric connector in an exemplary embodiment of the present disclosure, as Figures 1-3 shown, wherein the dashed arrow can represent the arrangement direction of the signal transmission terminal 121, the electric connector 1 includes a main body structure 11, a terminal assembly 12 and a cover 13. The main body structure 11 includes a terminal mounting portion 111 and a cover mounting portion 112, the terminal assembly 12 is arranged on the terminal mounting portion 111, the terminal assembly 12 includes a signal transmission terminal 121 and a limiting terminal 122, and the limiting terminal 122 is provided with a limiting structure 1221. The cover 13 is rotationally assembled on the cover mounting portion 112, and the signal transmission terminal 121 is provided with a clearance interval from the cover 13. The cover 13 has an open state and a buckled state, and when the cover 13 is in the buckled state, the limiting structure 1221 is located in a limiting position. When the cover 13 is in the open state, the cover 13 abuts against the limiting terminal 122, so that the limiting structure 1221 deviates from the limiting position.

[0032] The terminal assembly 12 includes a signal transmission terminal 121 and a limiting terminal 122, the limiting terminal 122 can be located in a limiting position when the cover 13 of the electrical connector 1 is in a buckling state, and then cooperates with the plug-in circuit board 2 to realize limiting fixation, avoiding the opening operation of the cover 13 before plugging the circuit board 2, reducing the cumbersome operation, and being more conducive to the automation of the production line. And the limiting terminal 122 can be offset from the limiting position by the abutment of the cover 13 when the cover 13 is in an open state, so as to release the limiting of the circuit board 2, and improve the convenience of plugging operation of the circuit board 2. During the rotation of the cover 13 relative to the cover mounting portion 112, the signal transmission terminal 121 and the cover 13 leave a clearance, avoiding the influence of the structure and function of the signal transmission terminal 121 by the cover 13, which helps to improve the use reliability of the electrical connector 1. Because the signal transmission terminal 121 and the cover 13 leave a clearance, the circuit board 2 will not form structural interference when the cover 13 is in a buckling state.

[0033] The limiting terminal 122 is used as a locking device, which locks and positions the circuit board 2 after being inserted, preventing contact failure caused by the retreat of the connection terminal of the stressed circuit board 2. The limiting terminal 122 has better strength and can effectively cope with the loosening failure caused by vibration, impact, drop and excessive FPC stress, and does not need to increase the product height, and can be applied to the design of various high products.

[0034] It should be noted that the signal transmission terminal 121 described above can be used to cooperate with the connection terminal of the circuit board 2 to realize conductive connection or signal transmission. The limiting terminal 122 described above can be used only for limiting fixation of the circuit board 2, or can have both limiting function and signal transmission function, and the present disclosure does not limit this.

[0035] The circuit board 2 involved in the present disclosure can be a conventional PCB (Printed Circuit Board), or an FPC (Flexible Printed Circuit), and the present disclosure does not limit this. The circuit board 2 is plugged with the electrical connector 1, so that the connection terminal of the circuit board 2 cooperates with the terminal assembly 12 of the electrical connector 1 to realize the corresponding conductive connection function. The cover 13 described above can be the piano cover of the electrical connector 1.

[0036] In some embodiments, in the arrangement direction of the signal transmission terminals 121, the terminal mounting portion 111 includes a middle section 1111 and end sections 1112 located on both sides of the middle section 1111, the signal transmission terminals 121 are arranged in the middle section 1111, and the limiting terminals 122 are arranged in at least one end section 1112. Arranging the signal transmission terminals 121 in the middle section 1111 of the terminal mounting portion 111 and arranging the limiting terminals 122 in the end sections 1112 can avoid interference of the limiting terminals 122 with the structure and function of the signal transmission terminals 121 when the limiting terminals 122 are limitedly matched with the circuit board 2.

[0037] For example, the end sections 1112 on both sides of the middle section 1111 are respectively provided with limiting terminals 122, so as to be limitedly matched with the circuit board 2 through the limiting terminals 122 on both sides, which helps to improve the stability of the insertion of the circuit board 2.

[0038] In other embodiments, when the structure of the limiting terminal 122 does not affect the signal transmission terminal 121, the limiting terminal 122 can also be arranged between two adjacent signal transmission terminals 121, so as to fix a specific position of the circuit board 2 or further improve the stability of the insertion of the circuit board 2.

[0039] In some embodiments, the limiting terminal 122 can include an end portion arranged away from the terminal mounting portion 111, and a limiting structure 1221 is arranged in the end portion, so as to be convenient for forming a limiting relationship with the circuit board 2 in position during the insertion of the circuit board 2.

[0040] The limiting terminal 122 described above can also include a root portion 1222 arranged opposite to the end portion, and a first section 1223 is arranged between the end portion and the root portion 1222, and the first section 1223 is provided with a support structure 14. Since the first section 1223 is located between the end portion and the root portion 1222 of the limiting terminal 122, the first section 1223 forms a lever structure by using the support structure 14 after being connected with the terminal mounting portion 111, and the limiting structure 1221 located in the end portion can be tilted when being forced on the other side of the connection with the terminal mounting portion 111, so as to be convenient for displacement away from the limiting position.

[0041] The first section 1223 can form a cantilever structure with the end and the root 1222 by the support structure 14, and the limiting terminal 122 is divided into a first part on one side of the support structure 14 and a second part on the other side of the support structure 14. The limiting structure 1221 is located in the first part, and the second part abuts against the cover 13. When the second part is stressed, the limiting structure 1221 can be deviated from the limiting position by the deformation of the limiting terminal 122 and the support structure 14. The support structure 14 can be a support rod, a support block, etc., and the present disclosure is not limited thereto. The support structure 14 and the limiting terminal 122 can be integrally formed or assembled by welding, bonding, clamping, etc.

[0042] In some embodiments, the length between the support structure 14 and the limiting structure 1221 can be greater than the length between the support structure 14 and the root 1222, so as to increase the length of the head force arm, and improve the elastic deformation reliability and accuracy of the first part.

[0043] In some embodiments, the limiting terminal 122 includes a root 1222 arranged close to the terminal mounting portion 111. When the cover 13 is in the open state, the cover 13 abuts against the root 1222 to deviate the limiting structure 1221 from the limiting position. The root 1222 facilitates the abutting cooperation with the cover 13, which helps to simplify the structure of the electrical connector 1 and reduce the deformation difficulty of the limiting terminal 122, so that the limiting structure 1221 obtains the expected displacement deviated from the limiting position.

[0044] The side of the cover 13 facing the terminal assembly 12 can be provided with a limiting recess 132, and the root 1222 includes a stepped structure. When the cover 13 is in the open state, the limiting recess 132 abuts against the end of the stepped structure, which can improve the cooperation stability of the root 1222 of the limiting terminal 122 and the cover 13, and increase the buffering capacity of the root 1222 under stress by using the stepped structure, so as to avoid the damage problems such as fracture of the limiting terminal 122 caused by the abutting pressure of the cover 13.

[0045] In the above embodiments, the cover 13 can include a rotating shaft 131 cooperating with the cover mounting portion 112, and at least part of the limiting recess 132 is arranged on the rotating shaft 131, so as to reduce the structural space occupied by the abutting relationship between the cover 13 and the limiting terminal 122, and improve the space utilization of the electrical connector 1.

[0046] In some embodiments, the limiting terminal 122 comprises a second segment 1224 connected with the limiting structure 1221, and the limiting structure 1221 is bent relative to the second segment 1224 to form a hook structure with the second segment 1224. By forming a limiting relationship with the hook structure and the circuit board 2, the structure arrangement is simplified, and the connection reliability of the limiting terminal 122 and the circuit board 2 is improved. The circuit board 2 can be provided with a groove structure or a protrusion structure matched with the hook structure, so as to be limited and matched with the hook structure during the plugging process of the circuit board 2, and the present disclosure is not limited in this regard.

[0047] It should be noted that the limiting terminal 122 can be made of metal to improve the structural strength of the limiting terminal 122 and ensure the connection reliability of the limiting terminal 122 and the circuit board 2.

[0048] The present disclosure further provides an electronic device comprising the circuit board 2 and the above-mentioned electric connector 1. The circuit board 2 is provided with a limiting matching part 21, and when the circuit board 2 is assembled and matched with the electric connector 1, the limiting matching part 21 is limited and fixed with the limiting structure 1221 in the plugging direction of the circuit board 2.

[0049] The circuit board 2 can be provided with a groove structure, a protrusion structure, a hook structure, etc. matched with the limiting structure 1221, so as to be limited and matched with the limiting structure 1221 during the plugging process of the circuit board 2, and the present disclosure is not limited in this regard. For example Figure 4 、 Figure 5 As shown in FIG. 11, the limiting structure 1221 can form a hook structure with the second segment 1224, and the circuit board 2 can be provided with a groove structure with an open edge. During the plugging process of the circuit board 2, the hook structure slides into the groove structure to form a limit when the circuit board 2 is inserted. When the cover 13 is in the open state, the cover 13 abuts against the limiting terminal 122 to make the limiting structure 1221 deviate from the limiting position, and the circuit board 2 is no longer limited by the limiting terminal 122, so that the circuit board 2 can be withdrawn from the electric connector 1.

[0050] The above-mentioned terminal assembly 12 comprises the signal transmission terminal 121 and the limiting terminal 122. The limiting terminal 122 can be located at the limiting position when the cover 13 of the electric connector 1 is in the buckling state, so as to be matched with the plugged circuit board 2 to achieve limiting and fixing, thereby avoiding the opening operation of the cover 13 before the plugging of the circuit board 2. The limiting terminal 122 can deviate from the limiting position by abutting against the cover 13 when the cover 13 is in the open state, so as to release the limiting of the circuit board 2 and improve the plugging operation convenience of the circuit board 2. During the rotation of the cover 13 relative to the cover mounting part 112, the signal transmission terminal 121 and the cover 13 leave a clearance, so as to avoid the influence of the operation of the cover 13 on the structure and function of the signal transmission terminal 121, and to improve the use reliability of the electric connector 1.

[0051] It should be noted that the electronic device can be one of a mobile phone, a tablet computer, a computer, a vehicle-mounted device, a medical device, a wearable device, and a robot, and the present disclosure is not limited thereto.

[0052] The above merely describes the preferred embodiments of the present disclosure and is not intended to limit the present disclosure in any form. Although the present disclosure has been disclosed as the above preferred embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make some minor changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present disclosure to obtain equivalent embodiments with equivalent changes.
