In some embodiments, a gap exists between the side wall of the back cover 109 and the side wall of the wire 110a, which reserves a space for subsequent connection between the back cover 109 and the outer wall of the second electrical component cavity 108.
In some embodiments, the back cover 109 is made of plastic.
In some embodiments, referring to
In some embodiments, a first gap exists between the first guide post 108a and the first guide post groove 109a, and a second gap exists between the second guide post 108d and the second guide post groove 109c. A size of the first gap is different from a size of the second gap.

In some embodiments, referring to
In some embodiments, at least two step portions 102 are arranged opposite to each other on the inner wall of the first electrical component cavity 105.
In some embodiments, the number of the step portions 102 may also be three, four, etc. In some embodiments, other different numbers can be selected according to actual needs.
In some embodiments, each step portion 102 includes two step surfaces parallel to each other and a contact surface connecting two step surfaces. The contact surface is parallel to the inner wall of the first electrical component cavity 105, and the two step surfaces are perpendicular to the contact surface.
In some embodiments, the step surfaces and the contact surface may also be not perpendicular to each other.
In some embodiments, referring to
In some embodiments, the step portion 102 may be integrally formed with the first electrical component cavity 105.
In some embodiments, the step portion 102 may be not integrally formed with the first electrical component cavity 105.
In some embodiments, when the width d of the step portion 102 protruding from the inner wall of the first electrical component cavity 105 is less than 1.2 mm, a contact area between subsequent claw structure and the step portion 102 is too small, thus the first electrical component 103 cannot be tightly clamped in the first electrical component cavity 105, and the first electrical component 103 may detach from the first electrical component cavity 105, and there is no space for disassembly tools, which is not convenient for disassembly. When the width d of the step portion 102 protruding from the inner wall of the first electrical component cavity 105 is greater than 2.0 mm, the overall size of the connector may increase, which affects a layout space of the overall connector.
Referring to
In some embodiments, during inserting the first electrical component 103 from the first side 101a into the first electrical component cavity 105, the claw structure 104 deforms under a squeezing force of the step portion 102. After the first electrical component 103 is inserted into the first electrical component cavity 105, the claw structure 104 restores to contact and lock the step portion 102.
In some embodiments, utilizing the deformation ability of the claw structure 104 itself, during inserting the first electrical component 103 into the first electrical component cavity 105, the claw structure 104 deforms under a squeezing force of the step portion 102, and is contracted towards the side wall of the first electrical component 103. After the first electrical component 103 is inserted into the first electrical component cavity 105, due to its elastic performance, the claw structure 104 restores to its initial state without the action of squeezing force, thereby contacting the step surface of the step portion 102 and locking the step portion 102.
In some embodiments, referring to
In some embodiments, in combination with the inherent characteristics of the claw structure 104, when the inclined angle is greater than 12 degrees, a connection force between the claw structure 104 and the side wall of the first electrical component 103 becomes smaller. Thus, when disassembling the first electrical component 103, the force is mostly concentrated on the claw structure 104, thus the insufficient strength of the claw structure 104 is not enough, and the claw structure 104 cannot provide enough strength to smoothly disassemble the first electrical component 103 from the first electrical component cavity 105, and the plastic claw structure may be easily broken during assembly and disassembly. When the inclined angle is less than 6 degrees, due to the small inclined angle, there is insufficient contact between the claw structure 104 and the step portion 102, thus the claw structure 104 cannot grip the step portion 102, which can easily cause falling off of the first electrical component 103.
In some embodiments, the claw structure 104 has an elastic modulus ranging from 0.3 to 0.5. The elastic modulus in this range can ensure that the claw structure 104 has appropriate deformation recovery ability and has appropriate hardness to achieve a rapid disassembly of the first electrical component 103.
In some embodiments, the claw structure 104 is made of a plastic.
In some embodiments, referring to
In some embodiments, under the action of the guide groove 107, it is convenient for the first electrical component 103 to be quickly and accurately installed into the first electrical component cavity 105.
In some embodiments, a width L of the claw structure 104 in a direction parallel to the side wall of the first electrical component 103 ranges from 4 mm to 10 mm.
In some embodiments, when the width L of the claw structure 104 in the direction parallel to the side wall of the first electrical component 103 is less than 4 mm, the width of the claw structure 104 is too small, which can easily cause insufficient connection strength between the first electrical component 103 and the first electrical component cavity 105, resulting in slipping between the first electrical component 103 and the first electrical component cavity 105. When the width L of the claw structure 104 in the direction parallel to the side wall of the first electrical component 103 is greater than 12 mm, it is easy to cause a material waste of the claw structure 104, leading to an increase in cost.
In some embodiments, a thickness a of the claw structure 104 ranges from 0.6 mm to 1.2 mm. When the thickness a of the claw structure 104 is less than 0.6 mm, the claw structure 104 is too thin, and cannot provide sufficient strength to lock the step portion 102, causing loosening between the first electrical component 103 and the first electrical component cavity 105. When the thickness a of the claw structure 104 is greater than 1.2 mm, the claw structure 104 is too thick, and there is no enough space between the side wall of the first electrical component 103 and the inner wall of the first electrical component cavity 105 to accommodate the claw structure 104, resulting in an insufficient force on the step portion 102 applied by the claw structure 104, and affecting the effective connection between the first electrical component 103 and the first electrical component cavity 105.
In some embodiments, referring to
In some embodiments, the plugging portion may be connected with an external circuit to achieve an electrical connection of the plug connector 100.
When disassembling the first electrical component 103, a tool is used to counter the claw structure 104 from the second side, causing the claw structure 104 to contract away from the inner wall of the first electrical component cavity 105, thereby withdrawing the first electrical component 103 from the first electrical component cavity 105.
Referring to
The mounting plate 101 includes a first side 101a, and the first side 101a includes an electrical component area 106.
A first electrical component cavity 105 and a second electrical component cavity 108 are arranged in the electrical component area 106 and extend through the mounting plate 101 from the first side 101a.
A first electrical component 103 is arranged in the first electrical component cavity 105, and a second electrical component 110 is arranged in the second electrical component cavity 108.
In some embodiments, the first electrical component 103 is removably connected with the first electrical component cavity 105, and the second electrical component 110 is removably connected with the second electrical component cavity 108.
In some embodiments, the plug connector 100 further includes a groove 121, a sealing ring 120 and a fixing plate 130.
The groove 121 is concave from the first side 101a into the mounting plate 101 perpendicular to the first side 101a, and the groove 121 surrounds an outer side of the electrical component area 106.
The sealing ring 120 is arranged in the groove 121, and a top surface of the sealing ring 120 protrudes from the first side 101a.
The fixing plate 130 is arranged on the first side 101a, and the fixing plate 130 has an opening 130a for exposing the electrical component area 106. The sealing ring 120 is arranged between the fixing plate 130 and the mounting plate 101.
In some embodiments, the sealing ring 120 is arranged in the groove 121, thus when mounting the fixing plate 130 on the first side 101a, the sealing ring 120 can achieve a sealed connection between the fixing plate 130 and the mounting plate 101, which can achieve a good waterproof and anti-fouling function. In addition, the fixing plate 130 is provided with the opening 130a for exposing the electrical component area 106. When the size of the opening 130a is not very precise and the fixing plate 130 cannot covers the mounting plate 101, since the top surface of the sealing ring 120 protrudes from the surface of the groove 121 (i.e. the first side 101a), the flexibility and elasticity of the sealing ring 120 can make up for the deficiencies caused by the size of the opening 130a, which can achieve effective mounting of the fixing plate 130 to the mounting plate 101, improve the quality of the plug connector 100 and improve production efficiency.
In some embodiments, after the sealing ring 120 is installed in the groove 121, the top surface of the sealing ring 120 protrudes from the first side 101a by 0.5 mm to 2 mm. When the fixing plate 130 is mounted on the mounting plate 101, an excess part of the sealing ring 120 exists between the fixing plate 130 and the mounting plate 101. Therefore, when the size of the opening 130a is larger than that of the electrical component area 106, a gap between the opening 130a and the electrical component area 106 can be filled with the excess part of the sealing ring 120 to ensure the sealing between the fixing plate 130 and the mounting plate 101, which can achieve effective mounting of the fixing plate 130 to the mounting plate 101 and reduce the processing difficulty and requirements of the fixing plate 130.
In some embodiments, a ratio of a volume of a part of the sealing ring 120 protruding from the first side 101a to a volume of the sealing ring 120 ranges from 0.2:1 to 0.3:1, which can achieve a best compression waterproof sealing effect when the fixing plate 130 is mounted on the mounting plate 101, and a compressed volume of the part of the sealing ring 120 is 20-30% of its original volume.
In some embodiments, a Shore hardness of the sealing ring 120 ranges from 30HA to 50HA, and an elastic coefficient of the sealing ring 120 ranges from 0.01 N/m to 0.5 N/m.
In some embodiments, selecting a reasonable range of Shore hardness and elastic coefficient can not only ensure that the sealing ring 120 can be compressed and provide good sealing effect, but also allow for corresponding floating during the installation process, which can achieve effective installation between the fixing plate 130 and the mounting plate 101, and thus have broad practical significance.
In some embodiments, the sealing ring 120 may be made of a mixture of a silicone and a phenyl silicone oil, and a mass ratio of the phenyl silicone oil to the silicone ranges from 0.01:1 to 0.03:1. The silicone contains 1%-3% phenyl silicone oil, which can increase a fluidity of the material. If the content of the phenyl silicone oil is too low, the fluidity of the material will be poor and the floating effect will not be good; and if the content of the phenyl silicone oil is too high, the overall material is soft and the sealing effect is not good.
In some embodiments, a depth of the groove 121 ranges 2 mm to 4 mm, and a width of the groove 121 ranges from 2 mm to 4 mm. When the depth or width of the groove 121 is too large, the volume of the sealing ring 120 is too large, which can increase costs. Moreover, if the sealing ring 120 is too large, a strength between the fixing plate 130 and the mounting plate 101 can be decreased, which cannot ensure the performance of the plug connector 100.
In some embodiments, there are one first electrical component cavity 105 and four second electrical component cavities 108 surrounding the first electrical component cavity 105, and the four second electrical component cavities 108 are symmetrically distributed in pairs on the electrical component area 106. That is, the first electrical component cavity 105 is arranged between adjacent second electrical component cavities 108.
In some embodiments, a pattern of the electrical component area 106 projected onto the first side 101a has a quasi-rectangular shape, and the four second electrical component cavities 108 are arranged at four top corners of the quasi-rectangular shape.
In some embodiments, the pattern of the electrical component area 106 projected onto the first side 101a can also have other shapes, which can be set according to actual needs.
In some embodiments, the number and position of the first electrical component cavity and the second electrical component cavity can also be set according to actual electrical needs.
In some embodiments, the first electrical component 103 and the second electrical components 110 can have different functions. By combining the first electrical component 103 and the second electrical components 110 on the plug connector 100, a hybrid energy storage conductive transmission connection can be achieved, which is convenient for coordination and connection between a plurality of connectors.

With the fixing post 120a inserted in the positioning hole 121a, when the sealing ring 120 floats or shifts, and the fixing post 120a trends to detach from the positioning hole 121a, a reaction force will be generated between the fixing post 120a and the positioning hole 121a to prevent the fixing post 120a from detaching from the positioning hole 121a, which can ensure that the sealing ring 120 can be always positioned in the groove 121 and ensure the sealing between the fixing plate 130 and the mounting plate 101.
