The connector assembly on the market generally includes a first connector and a second connector that dock with each other. However, during the use of the electrical connector, there is a risk that the first connector and the second connector are easy to slip off each other, which poses a great safety hazard to the use of the electrical connector.

[0003] The present application provides an electrical connector assembly and an unlocking tool, which are used to solve the risk that a first connector and a second connector are easy to slip off each other, causing a greater safety hazard in the use of the electrical connector.

[0004] A first aspect of the present application provides an electrical connector assembly, which includes a first connector and a second connector, the first connector being provided with a card slot, the second connector including a buckle, and the first connector and the second connector being snap-fitted together via the buckle and the card slot.

[0013] During the process of disconnecting the first connector from the second connector, the clamping portion can extend into the second accommodating cavity through the second opening and be detached from the first accommodating cavity.

[0014] In this solution, the mating portion is provided with an inclined first guide surface, and the clamping portion has an inclined second guide surface. During the connection between the first connector and the second connector, the first guide surface is in contact with the second guide surface, and the inclination angle of the first guide surface is β, satisfying 50°≤β≤70°.

[0015] In this solution, the reinforcing portion protrudes relative to the buckle in a direction toward the second connector, and a second gap is provided between the reinforcing portion and the second connector.

[0016] Along the thickness direction of the electrical connector assembly, the thickness of the reinforcement portion satisfies 0.5cm≤D1≤0.9cm, and / or the card slot further includes a notch, and along the width direction of the electrical connector assembly, the width of the notch satisfies 2.5cm≤D2≤3.5cm.

[0067] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0068] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0069] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0070] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0071] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0072] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0073] The present application embodiment provides an electrical connector assembly, such as Figure 1 , Figure 7 and Fig. 9 As shown, the electrical connector assembly includes a first connector 1 and a second connector 2, and the first connector 1 is provided with a card slot 11. The second connector 2 includes a buckle 21, and the first connector 1 and the second connector 2 are engaged and matched through the buckle 21 and the card slot 11. In the direction in which the first connector 1 and the second connector 2 are separated from each other, the buckle 21 has a first end face 212a, and the first end face 212a and the bottom wall 111 of the card slot 11 are inclined along the direction in which the first connector 1 and the second connector 2 are separated from each other, and the inclination directions of the two are opposite.

[0074] Among them, Figure 7 and 9 As shown, when the first connector 1 and the second connector 2 are in the connected state, the first end face 212a abuts against the bottom wall 111 of the slot 11, or the first end face 212a and the bottom wall 111 of the slot 11 have a first gap along the direction in which the first connector 1 and the second connector 2 disengage from each other.

[0075] When the first connector 1 and the second connector 2 are in the connected state, at least part of the structure of the buckle 21 is located in the slot 11, so that the buckle 21 and the slot 11 are snap-fitted. Compared with the conventional buckle snap-fitting structure, since the first end face 212a of the buckle 21 and the bottom wall 111 of the slot 11 in this embodiment are relatively inversely inclined along the direction in which the first connector 1 and the second connector 2 are separated from each other, it is difficult for the first end face 212a to separate from the slot 11 along the direction in which the first connector 1 and the second connector 2 are separated from each other, reducing the risk of the buckle 21 and the slot 11 being released from the snap-fitting, thereby improving the reliability and stability of the connection between the first connector 1 and the second connector 2, reducing the risk of accidental separation of the first connector 1 and the second connector 2, and thus helping to improve the safety of the electrical connector assembly.

[0076] It should be noted that, in the embodiments of the present application, Figure 2 As shown, the length direction of the electrical connector assembly is shown in the X direction in the figure, the width direction of the electrical connector assembly is shown in the Y direction in the figure, and the thickness direction of the electrical connector assembly is shown in the Z direction in the figure.

[0077] In a possible embodiment, when the first connector 1 and the second connector 2 are in a connected state, the first end face 212a abuts against the bottom wall 111 of the slot 11, that is, the first end face 212a and the bottom wall 111 of the slot 11 fit against each other, which helps to further reduce the risk of the first end face 212a detaching from the slot 11 along the direction in which the first connector 1 and the second connector 2 detach from each other.

[0078] In another possible implementation, Fig. 9 As shown, the first end face 212a and the bottom wall 111 of the card slot 11 have a first gap along the direction in which the first connector 1 and the second connector 2 are separated from each other. When the electrical connector assembly is subjected to an external force along the direction in which the first connector 1 and the second connector 2 are separated from each other, since the first end face 212a and the bottom wall 111 of the card slot 11 have the first gap, the risk of wear of the first end face 212a and the bottom wall 111 of the card slot 11 is reduced, and the service life of the buckle 21 and the card slot 11 is increased.

[0079] The buckle 21 and the slot 11 may be made of plastic material.

[0080] In addition, the electrical connector assembly provided in the present application can be applied to connectors on household inverters, or micro inverters, or household storage all-in-one machines. Among them, the first connector 1 can be a line-end connector, and the second connector 2 can be a board-end connector, or the first connector 1 can be a line-end connector, and the second connector 2 can also be a line-end connector, or the first connector 1 can be a board-end connector, and the second connector 2 can be a line-end connector. That is, the first connector 1 can be a line-end connector or a board-end connector, and the second connector 2 can be a line-end (board-end) connector or a board-end (line-end) connector, which can be selected according to actual needs, as long as the first connector 1 and the second connector 2 are engaged with the card slot 11 through the above-mentioned buckle 21.

[0081] In a possible implementation, Figure 3-Figure 6 As shown, the buckle 21 is provided with a reinforcing portion 211 a, which is beneficial to improving the structural strength of the buckle 21 and increasing the service life of the buckle 21 .

[0082] In a possible implementation, Figure 3-Figure 6 and Fig.11 As shown, the second connector 2 further includes a main body 22 , the reinforcing portion 211 a protrudes relative to the buckle 21 toward the second connector 2 , and a second gap is provided between the reinforcing portion 211 a and the main body 22 of the second connector 2 .

[0083] In this embodiment, the buckle 21 is a cantilever structure, that is, along the thickness direction Z of the electrical connector assembly, there is a second gap between the main body 22 and the buckle 21, so that the buckle 21 can smoothly enter the card slot 11 and engage with the card slot 11 along the length direction Z of the electrical connector assembly. The buckle 21 is provided with a reinforcing portion 211a, which is conducive to strengthening the structural strength of the buckle 21. After the buckle 21 and the card slot 11 are engaged and engaged for many times, the risk of the buckle 21 falling down is reduced, that is, the buckle 21 is deflected toward the main body 22, and the risk of the preset gap is reduced, thereby reducing the risk of the buckle 21 and the card slot 11 being unable to be plugged in after long-term use, improving the reliability of the buckle 21 and the card slot 11 being able to be smoothly plugged in, improving the convenience and reliability of the engagement of the first connector 1 and the second connector 2, and at the same time, it is conducive to increasing the service life of the buckle 21, thereby increasing the service life of the electrical connector assembly.

[0084] In a possible implementation, Fig.11 As shown, the thickness of the reinforcing portion 211a along the thickness direction Z of the electrical connector assembly satisfies 0.5 cm ≤ D1 ≤ 0.9 cm, where D1 can be 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm, etc.

[0085] When the thickness D1 of the reinforcing portion 211a is too large, that is, the volume of the reinforcing portion 211a is too large, the volume of the buckle 21 is too large, causing the thickness and volume of the second connector 2 to increase greatly, which is not conducive to the lightness of the electrical connector assembly. When the thickness D1 of the reinforcing portion 211a is too small, it is easy to cause the reinforcing portion 211a to fail to strengthen the buckle 21, reduce the anti-bending performance of the buckle 21, and be not conducive to the structural stability of the buckle 21. Therefore, in this embodiment, the thickness of the reinforcing portion 211a satisfies 0.5cm≤D1≤0.9cm, which is conducive to improving the structural strength of the buckle 21 and does not cause the risk of excessive thickness and volume of the buckle 21.

[0086] In a possible implementation, Figure 1 and Fig. 9 As shown, the inclination angle of the first end surface 212a relative to the direction in which the first connector 1 and the second connector 2 are separated from each other is α1, which satisfies 75°≤α1≤85°, and the inclination angle of the bottom wall 111 of the card slot 11 relative to the direction in which the first connector 1 and the second connector 2 are separated from each other is α2, which satisfies 75°≤α2≤85°. In some embodiments, α1 can be 75°, 76°, 78°, 80°, 82°, 84°, 85°, etc., and α2 can be 75°, 76°, 78°, 80°, 82°, 84°, 85°, etc.

[0087] Among them, the inclination angles of α1 and α2 can be the same or different, that is, when α1 is equal to α2, when the first connector 1 and the second connector 2 are in a connected state, the first end face 212a abuts against the bottom wall 111 of the slot 11; when α1 is not equal to α2, the first end face 212a and the bottom wall 111 of the slot 11 have a first gap along the direction in which the first connector 1 and the second connector 2 disengage from each other.

[0088] In this embodiment, when α1 and / or α2 are too large, that is, the first end face 212a and / or the bottom wall 111 of the slot 11 tends to be flat, which increases the risk of the first end face 212a disengaging from the slot 11 along the direction in which the first connector 1 and the second connector 2 disengage from each other, causing the slot 11 and the buckle 21 to be easily disengaged from each other, thereby greatly increasing the risk of the first connector 1 and the second connector 2 being easily disengaged from each other; when α1 and / or α2 are too small, the area of ​​the snap-fitting between the buckle 21 and the slot 11 is greatly reduced, thereby reducing the reliability and stability of the snap-fitting between the buckle 21 and the slot 11, or, there is a risk that the buckle 21 and the slot 11 cannot be snap-fitted, thereby causing the risk that the first connector 1 and the second connector 2 cannot be snap-fitted.

[0089] Therefore, in the present embodiment, 75°≤α1≤85° and 75°≤α2≤85° are satisfied, so that the buckle 21 and the slot 11 can be smoothly snap-fitted together, and it is beneficial to improve the reliability and stability of the snap-fitting between the slot 11 and the buckle 21, and improve the reliability and stability of the first connector 1 and the second connector 2 when they are in a connected state.

[0090] In a possible implementation, Figure 1 and Figure 7-Figure 9 As shown, the buckle 21 includes a first body 211 and a clamping portion 212 connected to the first body 211 , the clamping portion 212 has a first end surface 212 a , and the bottom wall 111 of the slot 11 has a first opening 112 for the clamping portion 212 to pass through, and the clamping portion 212 can be elastically deformed relative to the first body 211 .

[0091] When the first connector 1 needs to be connected with the second connector 2, the clamping portion 212 first enters the first opening 112, and then the clamping portion 212 is elastically deformed, so that the first end face 212a of the clamping portion 212 moves to a position where it abuts against the bottom wall 111 of the slot 11 or has a first gap, so that the buckle 21 is engaged with the slot 11, so that the first connector 1 needs to be connected with the second connector 2. When the first connector 1 needs to be disconnected from the second connector 2, the clamping portion 212 is driven to be elastically deformed, so that the first end face 212a of the clamping portion 212 can be disengaged to a position where it abuts against the bottom wall 111 of the slot 11 or has a first gap, and then the clamping portion 212 can be disengaged through the first opening 112, so that the first connector 1 and the second connector 2 are disconnected.

[0092] Therefore, the bottom wall 111 of the card slot 11 has a first opening 112 for the clamping portion 212 to pass through, so that the clamping portion 212 can smoothly clamp or release the clamping with the card slot 11, thereby improving the reliability and stability of the clamping and release of the first connector 1 and the second connector 2. At the same time, the clamping portion 212 can be elastically deformed, so that the first end face 212a of the clamping portion 212 can be separated from the position of abutting against the bottom wall 111 of the card slot 11 or having a first gap, thereby improving the convenience and reliability of the release of the first connector 1 and the second connector 2.

[0093] In a possible implementation, Figure 7 and Figure 8As shown, the first connector 1 includes a second body 113 and a mating portion 114 protruding relative to the second body 113, the mating portion 114 and the second body 113 enclose a card slot 11, a first accommodating cavity 115 is provided between the mating portion 114 and the second body 113, and the card slot 11 is connected to the first accommodating cavity 115 through a first opening 112. During the connection between the first connector 1 and the second connector 2, the engaging portion 212 can extend out of the first accommodating cavity 115 through the first opening 112 and engage with the card slot 11. Among them, the bottom wall 111 of the card slot 11 is arranged on the mating portion 114.

[0094] The buckle 21 and the slot 11 are of an axisymmetric structure, that is, the buckle 21 has at least two axisymmetric snap-fitting portions 212 and at least two first end faces 212a located at the at least two snap-fitting portions 212, and the slot 11 has at least two axisymmetric mating portions 114, and the at least two mating portions 114 have at least two bottom walls 111. When the first connector 1 is connected to the second connector 2, the snap-fitting of the buckle 21 and the slot 11 of the axisymmetric structure can reduce the risk of twisting and disengagement of the first connector 1 and the second connector 2, and further improve the stability and reliability of the snap-fitting of the first connector 1 and the second connector 2.

[0095] In this embodiment, when the first connector 1 is connected to the second connector 2, the snap-fitting portion 212 extends out of the first accommodating cavity 115 through the first opening 112, and then the two snap-fitting portions 212 are elastically deformed under the action of the squeezing of the side wall of the mating portion 114, so that the two snap-fitting portions 212 move toward each other along the width direction Y of the electrical connector assembly, and then the snap-fitting portions 212 can continue to move toward the first connector 1 along the length direction Z of the electrical connector assembly, and then the two snap-fitting portions 212 move away from each other along the width direction Y of the electrical connector assembly under the action of the rebound force and snap-fit ​​with the mating portion 114, so that the buckle 21 snaps into engagement with the slot 11.

[0096] Therefore, in this embodiment, during the connection between the first connector 1 and the second connector 2, the two snap-fitting portions 212 can move closer to each other in the first accommodating cavity 115, that is, the first accommodating cavity 115 is used to avoid the snap-fitting portion 212 so that the snap-fitting portion 212 can be elastically deformed, thereby improving the feasibility of the snap-fitting portion 212 continuing to move toward the first connector 1 along the length direction Z of the electrical connector assembly and snap-fitting with the mating portion 114.

[0097] In a possible implementation, Figure 2 , Figure 7 and Figure 8As shown, a second accommodating cavity 116 is further provided between the mating portion 114 and the second body 113, the first accommodating cavity 115 is communicated with the second accommodating cavity 116, and the second accommodating cavity 116 is communicated with the card slot 11 through the second opening 117. During the process of disconnecting the first connector 1 and the second connector 2, the card connection portion 212 can extend into the second accommodating cavity 116 through the second opening 117 and detach from the first accommodating cavity 115.

[0098] During the process of disconnecting the first connector 1 and the second connector 2, the driving clamping portion 212 is elastically deformed, so that the two clamping portions 212 move toward each other through the second opening 117 in the second accommodating cavity 116 along the width direction Y of the electrical connector assembly, so that the clamping portion 212 and the mating portion 114 are disconnected, thereby enabling the clamping portion 212 to move through the second accommodating cavity 116 along the length direction Z of the electrical connector assembly to the first accommodating cavity 115, and then the clamping portion 212 is disengaged from the card slot 11 through the first opening 112.

[0099] Therefore, in this embodiment, the second accommodating cavity 116 is connected to the card slot 11 through the second opening 117. During the process of disconnecting the first connector 1 and the second connector 2, the two clamping parts 212 can move closer to each other in the second accommodating cavity 116 through the second opening 117, that is, the second accommodating cavity 116 is used to avoid the clamping part 212 so that the clamping part 212 can be elastically deformed, thereby improving the feasibility of disconnecting the clamping part 212 from the mating part 114.

[0100] In a possible implementation, Fig.10 As shown, the mating portion 114 is provided with an inclined first guide surface 114a, and the clamping portion 212 has an inclined second guide surface 212b. During the connection between the first connector 1 and the second connector 2, the first guide surface 114a and the second guide surface 212b are in contact, that is, the first guide surface 114a and the second guide surface 212b have the same inclination angle. The inclination angle of the first guide surface 114a is β, which satisfies 50°≤β≤70°. β can be 50°, 55°, 60°, 65°, 70°, etc.

[0101] In this embodiment, the first beveled guide surface 114a and the second beveled guide surface 212b fit together to guide the connection process between the first connector 1 and the second connector 2, thereby improving the convenience and smoothness of the plugging of the first connector 1 and the second connector 2 and improving the user experience.

[0102] When the inclination angle β of the first guide surface 114a is too large or too small, that is, the first guide surface 114a tends to be horizontal or vertical, the guiding effect of the first guide surface 114a and the second guide surface 212b during connection is greatly reduced. Therefore, in this embodiment, satisfying 50°≤β≤70° is conducive to improving the guiding effect of the first guide surface 114a, and greatly improving the convenience and smoothness of the plug-in between the first connector 1 and the second connector 2.

[0103] The present application embodiment also provides an unlocking tool 4, such as Figure 7 , Fig.12 and Fig.14 As shown, the unlocking tool 4 is used for the electrical connector assembly in any of the above embodiments. The unlocking tool 4 at least includes a first unlocking end 41, and the first unlocking end 41 is used to unlock the buckle 21 and the card slot 11. The card slot 11 also includes a notch 118, which is provided in the second body 113 and communicates with the second accommodating cavity 116, and the above-mentioned clamping portion 212 is exposed through the notch 118.

[0104] In this embodiment, when the first connector 1 and the second connector 2 need to be disconnected, the first unlocking end 41 is extended into the notch 118, and the first unlocking end 41 can drive the clamping portion 212 to elastically deform, so that the two clamping portions 212 move toward each other along the width direction Y of the electrical connection component, so that the clamping portion 212 is released from the above-mentioned mating portion 114, thereby disconnecting the first connector 1 and the second connector 2.

[0105] In a possible implementation, Figure 7 As shown, along the width direction Y of the electrical connector assembly, the width of the notch 118 satisfies 2.5 cm ≤ D2 ≤ 3.5 cm. D2 can be 2.5 cm, 2.6 cm, 2.7 cm, 2.8 cm, 2.9 cm, 3.0 cm, 3.1 cm, 3.2 cm, 3.3 cm, 3.4 cm, 3.5 cm, etc.

[0106] When D2 is too large, that is, the width of the notch 118 is too large, there is a risk of inserting a finger into the notch 118, reducing the safety of the electrical connector assembly. When D2 is too small, that is, the width of the notch 118 is too small, it is easy to cause the space of the second accommodating cavity 116 to be too small, and there is a risk that the two clamping parts 212 do not have enough space to elastically deform along the width direction Y of the electrical connector assembly, which may easily lead to the risk that the clamping part 212 and the mating part 114 cannot be released from the clamping, and further cause the risk that the first connector 1 cannot be released from the second connector 2.

[0107] Therefore, in the present embodiment, 2.5cm≤D2≤3.5cm is satisfied so that the width of the notch 118 is moderate, thereby reducing the risk of the user accidentally reaching into the notch 118 and improving the safety of the electrical connector assembly. At the same time, it is convenient for the first unlocking end 41 to extend into the notch 118, thereby improving the reliability of the disconnection between the clamping portion 212 and the mating portion 114 via the first unlocking end 41 and further improving the reliability of the disconnection between the first connector 1 and the second connector 2.

[0108] In a possible implementation, Figure 8 , Fig.13 and Fig.14 As shown, the first unlocking end 41 has two first clamping portions 411, and the two first clamping portions 411 can approach each other or move away from each other. The first clamping portion 411 has a first inclined surface 411a. The first clamping portion 411 is used to extend into the card slot 11 when unlocking, and the first inclined surface 411a is used to fit with the first guide surface 114a of the buckle 21.

[0109] In this embodiment, when the unlocking tool 4 is used to unlock the electrical connector assembly, the first unlocking end 41 can be elastically deformed. At this time, the first inclined surface 411a of the first clamping portion 411 is in contact with the first guide surface 114a of the buckle 21, and then the first clamping portion 411 can drive the clamping portion 212 to elastically deform, thereby releasing the clamping engagement between the clamping portion 212 and the mating portion 114, thereby releasing the connection between the first connector 1 and the second connector 2.

[0110] Therefore, during the process of releasing the connection, the first inclined surface 411 a is in contact with the first guide surface 114 a , which is beneficial to improving the reliability and stability of the first unlocking end 41 being used to drive the clamping portion 212 to elastically deform.

[0111] In a possible implementation, Fig.12 , Fig.13 , Fig.15 and Fig.16 As shown, the electrical connector assembly further includes a connector 3 for clamping with the first connector 1, and the unlocking tool 4 further includes a second unlocking end 42, and the second unlocking end 42 includes two second clamping portions 421, and the two second clamping portions 421 can be close to each other or away from each other, and the second clamping portions 421 are used to drive the connector 3 to release the clamping connection with the first connector 1 when unlocking. The distance between the two first clamping portions 411 is smaller than the distance between the two second clamping portions 421.

[0112] In this embodiment, the connector 3 is used to connect an external wire (not shown in the figure) and the first connector 1. When the external wire needs to be connected or replaced, the connector 3 needs to be disconnected from the first connector 1 so that the external wire to be connected or replaced can be connected to the connector 3.

[0113] Specifically, the side wall of the first connector 1 may be provided with a snap-in hole, and the connector 3 may be provided with a snap-in protrusion, and the snap-in hole and the snap-in protrusion snap-in fit so that the first connector 1 and the connector 3 can be snap-in and detachably connected. When the first connector 1 and the connector 3 need to be released from connection, the second unlocking end 42 can be elastically deformed. At this time, the two second clamping portions 421 are used to support the snap-in protrusion, so that the snap-in protrusion and the snap-in hole are released from snap-in fit, so that the first connector 1 and the connector 3 are released from connection. Among them, the present application does not limit the specific structure of the snap-in protrusion and the snap-in hole, as long as it is different from the snap-in structure of the first connector 1 and the second connector 2, and the first connector 1 can be detachably connected to the connector 3.

[0114] In summary, the unlocking tool 4 can be used to unlock the first connector 1 and the second connector 2, and can also be used to unlock the first connector 1 and the connector 3. When unlocking is required, there is no need to use multiple unlocking tools to unlock electrical connector components of different structures, which facilitates disassembly and reduces costs.

[0115] In addition, the unlocking tool 4 is an integrally formed structure, which is easy to process and helps to reduce the risk of stress during processing and improve the forming rate of the unlocking tool 4.

[0116] The connecting member 3 may be a plastic base.

[0117] The above is only a specific implementation of the embodiment of the present application, but the protection scope of the embodiment of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed in the embodiment of the present application should be included in the protection scope of the embodiment of the present application. Therefore, the protection scope of the embodiment of the present application should be based on the protection scope of the claims.
