Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to an electrical connector. Background Art

[0002] An electrical connector for docking an electronic card generally includes a longitudinally extended insulating housing and a fixing component for fixing the electronic card. The fixing component is installed at the end of the insulating housing. After the electronic card is installed in the docking groove of the insulating housing, the fixing component can fix the end of the electronic card to limit the movement of the electronic card during signal transmission and ensure stable signal transmission.

[0003] Currently, the common way for the fixing component to fix the electronic card is as follows: The fixing component is provided with a limiting elastic piece inclined towards the direction close to the docking groove. When the electronic card is inserted into the docking groove along the groove body, the end of the electronic card abuts against the limiting elastic piece, and the limiting elastic piece deforms and applies a force to the electronic card, so that the end of the electronic card is fixed. However, the inclined limiting elastic piece will shorten the insertable length of the electronic card. When there are differences in the lengths of different batches of electronic cards, there will be a problem that the groove length of the docking groove does not match some of the electronic cards, affecting the insertion process of the electronic card; moreover, the groove length mismatch will cause interference between the edge of the electronic card and the limiting elastic piece, and the edge of the electronic card will be worn during multiple plugging and unplugging processes. Summary of the Invention

[0004] In view of this, this application provides an electrical connector that can solve at least one of the above technical problems.

[0005] This application provides an electrical connector that can be used to plug an electronic card. The electronic card is provided with a limiting protrusion and an avoidance recess. The electrical connector includes an insulating housing and a clamping component. The insulating housing is provided with a docking groove extending in a first direction, and the docking groove plugs the electronic card; the clamping component includes a connecting piece and a fixing piece. The connecting piece is connected to the end of the insulating housing along the first direction. The connecting piece is provided with an installation cavity and an opening part, and the opening part communicates with the installation cavity; at least part of the fixing piece is arranged in the installation cavity; the fixing piece arranged in the installation cavity is provided with a first elastic clamping piece and a second elastic clamping piece that are oppositely arranged along a second direction and extend along a third direction. A clamping position is formed between the first elastic clamping piece and the second elastic clamping piece. The electronic card is configured to be installed in the docking groove along the third direction along the clamping position and the opening part, and the first elastic clamping piece and the second elastic clamping piece are configured to respectively abut against two surfaces of the limiting protrusion of the electronic card along the second direction; wherein, the first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0006] For the electrical connector provided by this application, the first elastic clamping member and the second elastic clamping member are arranged opposite to each other in the second direction, that is, the first elastic clamping member and the second elastic clamping member clamp and limit the electronic card along the thickness direction of the electronic card. The arrangement of the first elastic clamping member and the second elastic clamping member will not affect the docking length of the docking groove, effectively solving the problem that the groove length of the docking groove does not match some electronic cards, reducing the wear caused by interference during the docking process of the electronic card, and extending the service life of the electronic card; moreover, the first elastic clamping member and the second elastic clamping member limit the electronic card along the thickness direction of the electronic card. While the electronic card can be stably clamped, the first elastic clamping member and the second elastic clamping member only deform during the installation process. After the electronic card is installed, the deformation is released, and the two are not prone to breakage.

[0007] In some embodiments, each of the first elastic clamping member and the second elastic clamping member includes a limiting portion and an elastic portion, and the elastic portion of each of the first elastic clamping member and the second elastic clamping member is inclined towards the center line of the clamping position; when the electronic card is installed in the docking groove, the limiting portion is configured to abut against two surfaces of the limiting protrusion of the electronic card along the second direction, and the elastic portion is configured to be received in the avoidance recess.

[0008] The elastic portions of the first elastic clamping member and the second elastic clamping member are inclined towards the center of the clamping position, and the elastic portions can form a guiding inclined surface to ensure the correct docking of the electronic card and the docking groove; and the elastic portions are configured to be received in the avoidance recesses, that is, after the electronic card is installed, the elastic portions do not need to abut against the electronic card, solving the problem that the elastic portions are prone to breakage after long-term deformation.

[0009] In some embodiments, the fixing member further includes a guiding portion, and the guiding portion is arranged in a region of the limiting portion away from the elastic portion along the third direction, and the guiding portion is configured to guide the electronic card into the clamping position.

[0010] The guiding portion can guide the electronic card into the clamping position, accelerating the installation process of the electronic card.

[0011] In some embodiments, the first elastic clamping member, the second elastic clamping member and the fixing member are of an integrally formed structure.

[0012] For the integrally formed structure of the first elastic clamping member, the second elastic clamping member and the fixing member, the connection strength of the three is higher, and the service life of the electrical connector can be extended.

[0013] In some embodiments, the fixing member and the connecting member are of a detachable structure, and at least part of the fixing member is received in the installation cavity.

[0014] The fixing member and the connecting member are of a detachable structure. When one of them is damaged, it can be replaced separately, reducing the maintenance cost of the electrical connector. At the same time, a part of the fixing member is received in the installation cavity of the connecting member, which can reduce the volume of the electrical connector and the system space occupied during the installation of the electrical connector.

[0015] In some embodiments, at least one clamping protrusion is provided on both side walls of the installation cavity along the second direction. The fixing member disposed in the installation cavity is further provided with at least one hook structure, and the hook structure is configured to be clamped with the clamping protrusion.

[0016] The connecting member and the fixing member are connected by the cooperation of the clamping protrusion and the hook structure, which facilitates the assembly and disassembly process of the two.

[0017] In some embodiments, the hook structure includes a first hook and a second hook, and the bending directions of the first hook and the second hook are opposite.

[0018] The bending directions of the first hook and the second hook are opposite, which facilitates receiving the acting force simultaneously to cause deformation of both, accelerating the installation process of the fixing member in the installation cavity. And it can avoid the slight movement of the fixing member during the signal transmission process of the electronic card and prevent it from separating from the connecting member.

[0019] In some embodiments, the hook structure and the fixing member are of an integrally formed structure.

[0020] The integrally formed hook structure and the fixing member have higher connection strength and can extend the service life of the electrical connector.

[0021] In some embodiments, the fixing member further includes an abutting member. Along the first direction, the abutting member is located on the side of the clamping position away from the insulating housing, and the abutting member is configured to abut against the end of the electronic card along the first direction.

[0022] The abutting member abuts against the end of the electronic card during the insertion process of the electronic card, reducing or avoiding the offset of the electronic card along the first direction and ensuring the correct docking of the electronic card with the docking groove.

[0023] In some embodiments, the abutting member includes an abutting surface. When observed along the second direction, the abutting surface is inclined in a direction away from the clamping position.

[0024] The inclined abutting surface ensures the correct docking of the electronic card and at the same time prevents wear between the abutting member and the electronic card, ensuring the service life of the electronic card. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0032] The present application provides an electrical connector 20, which can be used to plug an electronic card 10. The electronic card 10 is provided with a limit protrusion 101 and an avoidance recess 102; please refer to Figures 1 to 5, the electrical connector 20 includes an insulating housing 1 and a clamping assembly 201. The insulating housing 1 is provided with a docking groove 11 extending along a first direction X, and the electronic card 10 is inserted into the docking groove 11. The electrical connector further includes a clamping assembly, which includes a connecting member 2 and a fixing member 3. The connecting member 2 is connected to an end of the insulating housing 1 along the first direction X. The connecting member 2 is provided with an installation cavity 21 and an opening 22, and the opening 22 communicates with the installation cavity 21. At least a part of the fixing member 3 is disposed in the installation cavity 21. The fixing member 3 disposed in the installation cavity is provided with a first elastic clamping member 31 and a second elastic clamping member 32 that are oppositely disposed along a second direction Y and extend along a third direction. A clamping position 33 is formed between the first elastic clamping member 31 and the second elastic clamping member 32. The electronic card 10 is configured to be installed into the docking groove 11 along the third direction Z along the clamping position 33 and the opening 22, and the first elastic clamping member 31 and the second elastic clamping member 32 are configured to respectively abut against two surfaces of the limiting protrusion of the electronic card 10 along the second direction Y. Among them, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0033] In the electrical connector 20 provided in this application, the first elastic clamping member 31 and the second elastic clamping member 32 are oppositely disposed along the second direction Y, that is, the first elastic clamping member 31 and the second elastic clamping member 32 clamp and limit the electronic card 10 along the thickness direction of the electronic card 10. The settings of the first elastic clamping member 31 and the second elastic clamping member 32 will not affect the docking length of the docking groove 11, effectively solving the problem that the groove length of the docking groove 11 does not match some electronic cards 10, reducing the wear caused by interference during the docking process of the electronic card 10, and extending the service life of the electronic card 10. And, the first elastic clamping member 31 and the second elastic clamping member 32 limit the electronic card 10 along the thickness direction of the electronic card 10. While the electronic card 10 can be stably clamped, the first elastic clamping member 31 and the second elastic clamping member 32 only deform during the installation process. After the electronic card 10 is installed, the deformation is released, and the two are not easily broken.

[0034] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the features in the following embodiments and examples can be combined with each other.

[0035] In the following text, for convenience of description, as Figure 1 and Figure 3 shown, the longitudinal direction of the electrical connector 20 is defined as the first direction X, the thickness direction of the electrical connector 20 is defined as the second direction Y, the height direction / insertion direction of the electrical connector 20 is defined as the third direction Z, and the first direction X, the second direction Y, and the third direction Z are orthogonal to each other.

[0036] In some embodiments, a limiting protrusion 101 and an avoidance recess 102 are provided at the end of the electronic card 10 and are distributed along the third direction Z. It can be understood that the limiting protrusion 101 can be partially embedded in the clamping assembly 201, and due to the provision of the avoidance recess 101, part of the structure in the clamping assembly 201 can be avoided during the installation process of the electronic card 10, ensuring the smooth installation of the electronic card 10.

[0037] In some embodiments, please continue to refer to Figure 1 and Figure 2 , the electrical connector 20 specifically includes an insulating housing 1, electrical terminals 12, a clamping assembly 201 and a fixing assembly 202. Among them, the insulating housing 1 is the mounting base for the electrical terminals 12 and the clamping assembly 201. The insulating housing 1 is made of insulating material and is generally L-shaped or longitudinally elongated. In some embodiments, the insulating housing 1 is generally L-shaped and includes a first part 17 extending along the first direction X and a second part 18 extending from the first part 17 along the third direction Z. Among them, the first part 17 includes a pair of longitudinally elongated side walls 14 opposite to each other along the second direction Y and a top wall 15 and a bottom wall 16 opposite to each other along the third direction Z. The insulating housing 1 is further provided with a docking groove 11. When observed along the second direction Y, the docking groove 11 is located between the two side walls 14, and the docking groove 11 is opened from the top wall 15 towards the bottom wall 16 for the insertion of the electronic card 10.

[0038] The first part 17 of the insulating housing 1 is further provided with two rows of terminal mounting holes 13. The two rows of terminal mounting holes 13 are respectively located on both sides of the docking groove 11 along the first direction X. That is, along the second direction Y, the side walls 14, the terminal mounting holes 13, the docking groove 11, the terminal mounting holes 13 and the side walls 14 are arranged in sequence, and both ends of the terminal mounting holes 13 penetrate through the top wall 15 and the bottom wall 16 of the insulating housing 1 along the third direction Z.

[0039] The two rows of terminal mounting holes 13 specifically include a row of first terminal holes 131 and a row of second terminal holes 132. The first terminal holes 131 and the second terminal holes 132 are symmetrically arranged along the plane defined by the first direction X and the third direction Z. They are respectively located on both sides of the docking groove 11 along the first direction X, and the openings of the first terminal holes 131 and the second terminal holes 132 both face the docking groove 11, so that the first terminal holes 131 and the second terminal holes 132 are connected to the docking groove 11 along the second direction Y. It can be understood that the first terminal holes 131 and the second terminal holes 132 are used for installing the electrical terminals 12. They are respectively located on both sides of the docking groove 11 along the first direction X, and both the first terminal holes 131 and the second terminal holes 132 are connected to the docking groove 11. After the electronic card 10 is docked with the docking groove 11, the part of the electrical terminals 12 extending into the docking groove 11 in the first terminal holes 131 and the second terminal holes 132 can be connected to the electronic card 10, thereby realizing reliable electrical connection and stable signal transmission between the electronic card 10 and the electrical connector 20.

[0040] The fixing assembly 202 is fixed to the second portion 18 of the insulating housing 1. The clamping assembly 201 and the fixing assembly 202 are used to further fix the electronic card 10 inserted in the docking slot 11 along the third direction Z. It can be understood that the docking slot 11 is used to limit the displacement of the electronic card 10 along the first direction X and the second direction Y, and the clamping assembly 201 and the fixing assembly 202 are used to limit the displacement of the electronic card 10 along the second direction Y and the third direction Z. Specifically, the two are connected with the limiting protrusion 101 of the electronic card 10 to complete the limiting of the electronic card 10, and then through the cooperation between the docking slot 11 and the clamping assembly 201, the connection stability between the electronic card 10 and the docking slot 11 during signal transmission can be guaranteed.

[0041] In some embodiments, please continue to refer to Figure 4 The clamping assembly 201 includes a connector 2, which is connected to the end of the insulating shell 1 along the first direction X. For example, the connector 2 can be connected to the end of the first part 17 of the insulating shell 1 away from the second part 18. The connector 2 is approximately a columnar structure, and is provided with an installation cavity 21 and an opening 22. The installation cavity 21 passes through the connector 2 along the third direction Z, and the opening 22 is arranged on the side of the connector 2 close to the insulating shell 1, extending along the third direction Z and connecting the installation cavity 21 with the outside. It can be understood that when the connector 2 is installed to the end of the insulating shell 1, the opening 22 faces the electronic card 10, and can connect the installation cavity 21 with the docking slot 11. Then, when the electronic card 10 is installed, part of the electronic card 10 can enter the docking slot 11 along the opening 22, that is, guide the installation of the electronic card 10, and accelerate the docking efficiency between the docking slot 11 and the electronic card 10.

[0042] It should be noted that the present application does not limit the connection method between the connector 2, the fixing assembly 202 and the insulating housing 1. Specifically, it can be a detachable connection method such as a snap, an intermediate connector 2 or a fastener, or a non-detachable connection method such as bonding or welding, which can be selected according to actual needs. Optionally, in the present application, the connector 2, the fixing assembly 202 and the insulating housing 1 are detachably connected.

[0043] In some embodiments, please continue to refer to Figure 5 The clamping assembly 201 also includes a fixing member 3. The fixing member 3 and the connecting member 2 are detachable structures. Please continue to refer to Figure 3, at least a part of the fixing member 3 is received in the installation cavity 21. It can be understood that the fixing member 3 and the connecting member 2 are detachable structures, and the connecting member 2 and the insulating housing 1 are detachably connected. If one of the fixing member 3 and the connecting member 2 is damaged, it can be replaced separately, reducing the maintenance cost of the electrical connector 20; at the same time, along the third direction Z, a part of the fixing member 3 is received in the installation cavity 21 of the connecting member 2, which can reduce the volume of the clamping assembly 201, and further reduce the volume of the electrical connector 20, reducing the system space occupied when the electrical connector 20 is installed.

[0044] Specifically, please continue to refer to Figures 3 to 5 , at least one clamping protrusion 211 is provided on two inner wall surfaces of the installation cavity 21 opposite to each other along the second direction Y. The fixing member 3 disposed in the installation cavity 21 is provided with at least one hook structure 35. Optionally, two clamping protrusions 211 are provided on the connecting member 2 of the present application. The hook structure 35 includes a first hook 351 and a second hook 352, and the bending directions of the first hook 351 and the second hook 352 are opposite. In the present application, when the fixing member 3 is installed along the third direction Z, the first hook 351 and the second hook 352 extend into the installation cavity 21. At this time, the fixing member 3 can be installed on the connecting member 2 through the cooperation of the first hook 351, the second hook 352 and the clamping protrusion 211. It can be understood that the connecting member 2 and the fixing member 3 are connected through the cooperation of the clamping protrusion 211 and the hook structure 35, and the assembly and disassembly processes of the connecting member 2 and the fixing member 3 are simple; moreover, the bending directions of the first hook 351 and the second hook 352 are opposite, which is convenient for receiving acting forces simultaneously to cause deformation of both, accelerating the installation and disassembly processes of the fixing member 3 in the installation cavity 21; at the same time, the first hook 351 and the second hook 352 with opposite bending directions can also prevent the fixing member 3 from having a slight movement during the signal transmission process of the electronic card 10, avoiding separation from the connecting member 2 during the transmission process.

[0045] As an optional technical solution of the present application, the hook structure 35 and the fixing member 3 can be an integrally formed structure or a combined structure. Among them, the combined structure includes bonding, welding or detachable connection, etc. It can be understood that when the hook structure 35 and the fixing member 3 are an integrally formed structure, the overall strength of the fixing member 3 is high and the service life is longer, and thus the service life of the electrical connector 20 can be extended; when the hook structure 35 and the fixing member 3 are a detachable structure, if one of them is damaged, it can be replaced separately, reducing the maintenance cost of the fixing member 3. Optionally, the hook structure 35 and the fixing member 3 of the present application are an integrally formed structure.

[0046] In some embodiments, please continue to refer to Figure 5, the fixing member 3 is provided with a first elastic clamping member 31 and a second elastic clamping member 32 that are oppositely arranged along the second direction Y and extend along the third direction Z. A clamping position 33 is formed between the first elastic clamping member 31 and the second elastic clamping member 32. The clamping position 33 communicates with the installation cavity 21. The electronic card 10 can be installed into the docking groove 11 along the clamping position 33 and the opening 22. It can be understood that the first elastic clamping member 31 and the second elastic clamping member 32 are oppositely arranged along the second direction Y, that is, the first elastic clamping member 31 and the second elastic clamping member 32 can clamp and limit the electronic card 10 along the thickness direction of the electronic card 10. The arrangement of the first elastic clamping member 31 and the second elastic clamping member 32 does not affect the docking length of the docking groove 11, effectively solving the problem that the groove length of the docking groove 11 does not match some electronic cards 10; moreover, during the insertion process of the electronic card 10, its edge will not interfere with the first elastic clamping member 31 and the second elastic clamping member 32, solving the wear problem during the docking process and extending the service life of the electronic card 10; at the same time, the first elastic clamping member 31 and the second elastic clamping member 32 limit the electronic card 10 along the thickness direction of the electronic card 10, and only deform during the installation process. After the electronic card 10 is installed, the two are released from deformation, and the clamping stability is high, which can reduce the influence of vibration on the connection stability between the electronic card 10 and the docking groove 11.

[0047] As an optional technical solution of the present application, the first elastic clamping member 31, the second elastic clamping member 32 and the fixing member 3 can be an integrally formed structure or a combined structure, where the combined structure includes bonding, welding or detachable connection, etc. It can be understood that when the first elastic clamping member 31, the second elastic clamping member 32 and the fixing member 3 are an integrally formed structure, the overall strength of the fixing member 3 is high and the service life is longer, and thus the service life of the electrical connector 20 can be extended; when the first elastic clamping member 31, the second elastic clamping member 32 and the fixing member 3 are a detachable structure, if one of them is damaged, it can be replaced separately, reducing the maintenance cost of the fixing member 3. Optionally, the first elastic clamping member 31, the second elastic clamping member 32 and the fixing member 3 of the present application are an integrally formed structure.

[0048] Each of the first elastic clamping member 31 and the second elastic clamping member 32 specifically includes a limiting portion 321 and an elastic portion 322. The elastic portion 322 is connected to the body of the fixing member 3 through the limiting portion 321, that is, the elastic portion 322 is closer to the insulating housing 1 than the limiting portion 321, and the elastic portions 322 of the first elastic clamping member 31 and the second elastic clamping member 32 are inclined in the direction close to the center line of the clamping position 33, that is, the first elastic clamping member 31 and the second elastic clamping member 32 approximately enclose a V-shaped structure. It can be understood that the elastic portions 322 of the first elastic clamping member 31 and the second elastic clamping member 32 are inclined towards the center of the clamping position 33, and the two elastic portions 322 can form a guiding inclined surface. During the installation process of the electronic card, the guiding inclined surface can guide a part of the electronic card 20 into the clamping position 33 and pass through the elastic portion 322, so that the limiting protrusion 101 of the electronic card 10 is received between the two limiting portions 321. After the electronic card 10 passes through the elastic portion 322, the elastic portion 322 is deformed and received in the avoidance concave portion 102 of the electronic card 10, that is, after the electronic card 10 is installed, the elastic portion 322 does not need to abut against the electronic card 10, solving the problem that the elastic portion 322 is prone to breakage after long-term deformation; and, the elastic portion 322 received in the avoidance concave portion 102 of the electronic card 10 is inclined, and the distance between the two elastic portions 322 is less than the thickness of the electronic card 10, thereby avoiding the electronic card 10 from detaching during use and further improving the docking stability of the electronic card 10.

[0049] Further, the fixing member 3 includes a guiding portion 34. The guiding portion 34 is disposed in a region of the limiting portion 321 away from the elastic portion 322, and the guiding portion 34 can guide the electronic card 10 into the clamping position 33. It can be understood that the guiding portion 34 can guide the electronic card 10 into the clamping position 33 and accelerate the installation process of the electronic card 10.

[0050] It should be noted that, in order to ensure the correct installation of the electronic card 10, the guiding portion 34, the limiting portion 321 and the elastic portion 322 in this application are all arc-shaped structures. It can be understood that when the installation of the electronic card 10 has a positional deviation, the arc-shaped structure can guide the electronic card 10 to the correct installation position and accelerate the docking process between the electronic card 10 and the docking groove 11.

[0051] In some embodiments, please continue to refer to Figure 5, the fixing member 3 is further provided with an abutting member 36. The abutting member 36 is approximately columnar in structure and is arranged at one end of the clamping position 33 away from the insulating housing 1. When the electronic card 10 is inserted, the abutting member 36 can abut against the end of the electronic card 10, reducing or avoiding the offset of the electronic card 10 in the first direction X and ensuring the correct docking of the electronic card 10 with the docking groove 11. Specifically, the abutting member 36 includes an abutting surface 361. When observed in the third direction Z, the abutting surface 361 is inclined away from the clamping position 33, that is, when observed in the second direction Y, the cross-sectional shape of the abutting member 36 is a right trapezoid. It can be understood that the inclined abutting surface 361 can ensure the correct docking of the electronic card 10, and at the same time, there will be no wear due to interference between the abutting member 36 and the electronic card 10, ensuring the service life of the electronic card 10.

[0052] In the actual application process, the clamping assembly 201 is assembled to the insulating housing 1. Some electronic cards 10 enter and pass through the clamping position 33 through the guiding portion 34 of the fixing member 3, and then move along the opening portion 22 to the docking groove 11. At this time, the limiting protrusion 101 of the electronic card 10 is received between the two limiting portions 321, and after the electronic card 10 passes through the elastic portion 322, the elastic portion 322 is deformed and received in the avoiding concave portion 102 of the electronic card 10. The limiting portion 321 restricts the movement of the electronic card 10 in the second direction Y, completing the fixing process of the electronic card 10.

[0053] In addition, those of ordinary skill in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the scope of the essential spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope of the disclosure of the present application.
