Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At least one embodiment of the present disclosure provides a female plug and an electrical connector. The electrical connector includes a male plug and a female plug. The male plug includes a male electrode including a first mating portion. The female plug comprises a water-tight filling material, a female shell and a female electrode fixed in the female shell, wherein the female electrode comprises a second plugging part, and the second plugging part comprises a female cavity for being inserted into the first plugging part. At least a portion of the water-tight filler material is filled in the female chamber. Thus, when the first inserting part of the male electrode is inserted into the female cavity in the second inserting part of the female electrode, the filling material is extruded to wrap the first inserting part of the male electrode, so that a gap between the first inserting part and the second inserting part is filled, and water is prevented from entering the female cavity.

The specific structure of the female plug and the electrical connector according to at least one embodiment of the present disclosure will be described below with reference to the accompanying drawings. It should be noted that the electrical connector includes a female plug, and therefore, in the embodiments, the related design of the female plug is described simultaneously when describing the structure of the electrical connector.

As shown in fig. 1, 2A, 2B, and 3 to 9, in the electrical connector, the male plug 10 includes the male electrode 12, and the male electrode 12 includes the first mating portion 123. The female plug 20 includes a water-tight filling material 50, a female housing 21, and a female electrode 22 fixed in the female housing 21. The female electrode 22 includes a second mating portion 223, and the second mating portion 223 includes a female chamber (a mating cavity 2230 described below). At least a portion of the water-tight filling material 50 is filled in the female chamber. When the first mating part 123 of the male electrode 12 is inserted into the female chamber in the second mating part 223 of the female electrode 22, the filling material 50 is pressed to fill the peripheral gap, including the inclusion of the second mating part 223, so that external water does not intrude into the female chamber.

In at least one embodiment of the present disclosure, an electrical connector is provided in which a portion of the filler material is located in the female cavity and another portion is located in the cavity of the female housing for receiving the second mating part. The second inserting part of the female electrode is simultaneously wrapped by the filling material, so that the first inserting part and the second inserting part are further prevented from being influenced by water, and the electric leakage is avoided. It should be noted that the distribution of the filling material can be determined according to the actual process manner. For example, when the male plug is not inserted into the female plug, the filling material may be injected only into the female cavity, and when the first inserting part of the male electrode is inserted, the filling material overflows under the squeezing action of the first inserting part, the overflowing filling material not only fills the gap between the first inserting part and the second inserting part, but also directly overflows from the female cavity, and the filling material overflowing from the female cavity is distributed to the outer side of the second inserting part under the blocking action of the male electrode (or the male plug), that is, distributed to the space between the female housing and the second inserting part, so as to wrap the second inserting part; in another process, an encapsulating material may be injected into both the inner side (i.e., the female cavity) and the outer side (i.e., the space between the female housing and the second mating part) of the second mating part to wrap the first mating part and the second mating part, and may be completely isolated from the outside to prevent electrical leakage.

In the electrical connector provided in at least one embodiment of the present disclosure, the filling material may include a thermally conductive insulating material, and the filling material substantially fills a gap between the first mating part and the second mating part, so as to have a large contact area with the first mating part and the second mating part, and in a case where the filling material is selected to be a thermally conductive material, the heat dissipation capability of the electrical connector may be greatly improved. For example, the filler material may include a thermally conductive silicone grease. The heat conduction silicone grease can be beneficial to the conduction of heat generated at the first inserting part and the second inserting part, and the phenomenon that the electric connector is fused due to serious heat accumulation is avoided.

In the embodiments of the present disclosure, the specific structure of the electrical connector may be designed according to actual process requirements under the condition that the above design is satisfied. In the following, in one embodiment of the present disclosure, an electrical connector having a relatively complete design is provided, and the technical principle and effect of the design of the present disclosure will be described in conjunction with the electrical connector.

For example, in the electrical connector provided in an embodiment, the male plug further includes a male housing, the male housing includes a first connection section, a first fixing section and a first plugging section that are sequentially connected, the first connection section, the first fixing section and the first plugging section respectively define a first connection cavity, a first fixing cavity and a first plugging cavity, the male electrode further includes a first connection portion and a first fixing portion, the first connection portion, the first fixing portion and the first plugging portion are sequentially connected, the first fixing portion is fixed in the first fixing cavity, and the first connection portion and the first plugging portion are respectively located in the first connection cavity and the first plugging cavity; in addition, female casing is including the second linkage segment that connects gradually, second fixed segment and second grafting section, the second linkage segment, second fixed segment and second grafting section are injectd respectively and are connected the chamber, the fixed chamber of second and second grafting chamber, public electrode still includes second connecting portion and second fixed part, second connecting portion, second fixed part and second grafting portion connect gradually, the second fixed part is fixed in the fixed chamber of second, second connecting portion and second grafting portion are located second connection chamber and second grafting chamber respectively. The first and second connection portions are configured for connection of an external conductor, with the first plug-in section inserted into the female chamber, at least part of the second plug-in section being inserted into the gap of the first plug-in section and the first plug-in section.

In a specific example of this embodiment, as shown in fig. 1, fig. 2A, fig. 2B and fig. 3 to fig. 9, the male housing 11 includes a first connecting section 111, a first fixing section 112 and a first plugging section 113 which are connected in pairs in sequence, and a first connecting cavity, a first fixing cavity and a first plugging cavity are formed in the first connecting section 111, the first fixing section 112 and the first plugging section 113, respectively. For example, the male housing 11 is formed substantially as a cylindrical housing, and thus the male electrode 12 may be designed substantially in a cylindrical shape. The male electrode 12 includes a first connecting portion 121, a first fixing portion 122 and a first plugging portion 123 connected in sequence, the first fixing portion 122 is fixed in the first fixing cavity in a matching manner, and the first connecting portion 121 and the first plugging portion 123 are suitable for being coaxially arranged in the first connecting cavity and the first plugging cavity.

For example, in this example, the first connection part 121 forms a hollow cylinder having a connection chamber 1210 therein, an end of a wire (e.g., a first wire described below) distant from the first electrical appliance (e.g., a battery or an electronic device described below) may be welded in the connection chamber 1210, and the first socket part 123 may be formed in a hollow cylinder shape to reduce material. For example, the male electrode 12 may be pre-embedded within the male housing 11 during the molding of the male housing 11.

In this example, the female housing 21 includes a second connection section 211, a second fixing section 212, and a second plugging section 213 which are connected in pairs in sequence, and a second connection cavity 2101, a second fixing cavity 2102, and a second plugging cavity 2103 are formed in the second connection section 211, the second fixing section 212, and the second plugging section 213, respectively. For example, the female housing 21 is formed substantially in a cylindrical shape, and the female electrode 22 is formed substantially in a cylindrical shape. The female electrode 22 includes a second connecting portion 221, a second fixing portion 222 and a second inserting portion 223 connected in sequence, the second fixing portion 222 is fixed in the second fixing cavity 2102 in a matching mode, and the second connecting portion 221 and the second inserting portion 223 are suitable for being coaxially arranged in the second connecting cavity 2101 and the second inserting cavity 2103.

For example, in this example, the second connection part 221 forms a hollow cylinder having the second connection cavity 2110 therein, one end of a wire (e.g., a second wire described below) far from the second electrical appliance (e.g., a battery or an electronic device described below) may be welded in the connection cavity 2110, and the second insertion part 223 may be formed in a hollow cylinder having an insertion cavity 2230 (equivalent to the female cavity described above) inside. In this embodiment, the female electrode 22 may be embedded in the female housing 21 during the molding process.

For example, in this example, the second plug section 213 has a fitting groove 2131 formed on an outer peripheral surface thereof, the fitting groove 2131 being adapted to fit the waterproof rubber ring 30. The circumferential surface of the second mating portion 223 is formed with an elastic hole 2231 along the axial direction thereof, and the elastic hole 2231 penetrates through the end surface of the second mating portion 223 away from the second connecting portion 221. The circumferential surface of the second mating portion 223 is further formed with a ring of mating grooves 2232, and the mating grooves 2232 are adapted to fix the elastic collar 40. For example, a guide surface is formed between the circumferential surface of the plugging chamber 2230 and the end surface of the second plugging portion 223 away from the second connection portion 221.

For example, in this example, the first mating part 123 of the male electrode 12 is mated with the mating cavity 2230 of the second mating part 223, and when mated, the peripheral wall of the second mating part 223 is elastically deformed, and the peripheral wall of the second mating part 223 makes the peripheral wall of the first mating part 123 mate with the mating cavity 2230 under the elastic restoring force of the elastic collar 40 and itself.

For example, before the first plug part 123 is plugged into the second plug part 223, the filling material 50 is injected into the plug cavity 2230; alternatively, filler material 50 is injected into both plug cavity 2230 and second plug cavity 2103.

The filling material has certain fluidity, and in the application process of the electrical connector, the filling material may face shaking, collision and the like, which may cause the filling material to overflow and run off, thereby causing the sealing effect of the filling material to be reduced, and reducing the reliability of the electrical connector.

In at least one embodiment of the present disclosure, a valve is provided in the female plug to seal the filling material to prevent the filling material from escaping. For example, the chamber of the female housing for receiving the second plug part comprises an opening and the female plug further comprises a valve. The valve is fixed on the female shell and positioned at the opening, so that a cavity of the female shell, which is used for accommodating the second inserting part, is a closed cavity. The valve is formed by the concatenation of a plurality of separator parts, and includes the baffle, and this baffle is formed by having the concatenation of elastic a plurality of separator parts. In a case where the first mating part is not inserted into the female chamber, the adjacent separating parts contact each other such that a boundary line between the adjacent separating parts is a ray line segment of a common end point. The baffle of valve designs into a plurality of separation parts for first grafting portion can pass through the baffle, and when first grafting portion did not pass through, the separation part concatenation together can block filling material, so as to avoid filling material to spill over. Illustratively, as shown in fig. 2A, 2B, 4, and 10 to 11, a valve 23 is disposed at an opening (e.g., an opening of the second plugging chamber 2103 in the above example) of the female housing into which the male electrode is to be inserted, and a baffle of the valve 23 is formed by splicing a plurality of separating portions 110. One end of all the separating portions 110 extends to the center (e.g., the center of a circle) of the baffle, i.e., the boundary line 231 of adjacent separating portions 110 is a ray (here, a line segment) diverging outward from the center. Upon insertion of the first socket part of the male electrode, the separation parts 110 are separated from each other from the center so that the first socket part can pass through the valve 23. For example, the separation part 110 may be regarded as being formed by cutting (notching) a complete baffle in which the material of the baffle is not cut off, and the separation parts 110 thus formed are maintained in a state of being in contact with each other, i.e., no space is generated between the separation parts 110, thereby maintaining the sealing effect against the filling material 50.

In the electrical connector provided in at least one embodiment of the present disclosure, the number of the separation portions is not limited, and may be provided as three, four, or more. Illustratively, as shown in fig. 4 and 10, the four separating portions are provided, and the ray segments (the boundary lines 231) form a cross shape. It should be noted that, the larger the number of the separating portions, the smaller the gap between the separating portions when the common electrode is inserted, so that the valve still has a better sealing function to reduce the overflow of the filling material, but when the common electrode is not inserted, the strength of the separating portions is not high because of the relatively smaller size, and the blocking effect on the filling material is smaller; on the contrary, the smaller the number of the separating portions, the larger the gap between the separating portions when the common electrode is inserted, so that the sealing function of the valve at this time is small, and there is a risk of overflowing of the filling material, but when the common electrode is not inserted, the separating portions have a relatively large size, so that the strength is high, and the blocking effect on the filling material is better. Thus, under the condition that the four separating parts are arranged, the advantages can be taken into consideration, so that the separating parts can maintain a good sealing effect on the filling material all the time while keeping high strength.

In at least one embodiment of the present disclosure, an electrical connector is provided in which the valve further includes a fixing portion and a plurality of ribs. The fixed part is annular and is fixed on the female shell, and the separating part is fixed on the inner side of the annular fixed part. The ribs are located on a side of the baffle plate facing the second mating part, and each of the separating parts is connected to at least one of the ribs. One end of each rib is fixed on the corresponding separating part, the other end of each rib is fixed on the fixing part, and each rib is of an elastic structure. So, when filling material presents the state of spilling over, thereby the rib can present tensile state and hinder the separation portion and warp to avoid filling material to spill over, and the rib is because the design is for elastic construction, is compressed deformation easily, and when first grafting portion passed through the valve, the rib can not hinder the deformation of separation portion, thereby allows first grafting portion to pass through the valve, promptly, the design of rib makes the valve have one-way function of passing through. Illustratively, as shown in fig. 11-14 (fig. 11 and 12 show two opposite sides of the valve, respectively), a rib 130 is provided on the side of each separator 110 facing the parent electrode. The valve includes a ring-shaped fixing portion 120, and the inner side of the fixing portion 120 fixes the separating portion 110, i.e., the separating portion 110 is fixed on the female housing by the fixing portion 120. One end of the rib 130 is connected to the separating part 110, and the other end is connected to the fixing part 120. For the elastic rib 130 to be easily bent when both ends thereof are compressed, and to be stretched when both ends thereof are pulled, the force required for stretching is much larger than that required for bending at the same degree of deformation as compared to bending. Because the ribs 130 are located on the side of the separation portion 110 facing the filling material, the force applied to the separation portion 110 by the filling material when overflowing may cause the ribs 130 to stretch, while the force applied when inserting the male electrode may cause the ribs 130 to bend, which may make it difficult for the filling material to overflow while allowing the male electrode to easily pass through the valve. For example, the separating part 110 and the fixing part 120 may be integrally formed.

In at least one embodiment of the present disclosure, an electrical connector is provided in which a rib includes a main body portion and a plurality of branch portions. One end of the main body part is fixed to the fixing part, and the other end of the main body part is fixed to one end, which is far away from the fixing part, of the corresponding separating part. The plurality of branch parts are symmetrically distributed on two sides of the main body part, one end of each branch part is connected to the edge of the corresponding separating part, and the other end of each branch part is connected to the main body part or the main body part connected with the same separating part. So, main part and branch portion cooperate in order to strengthen the peripheral intensity of separation portion, avoid filling material to spill over from the edge of separation portion, in addition, branch portion symmetric distribution is in the both sides of main part for the atress distribution of separation portion is even, avoids the separation portion to appear the atress inequality and local deformation appears when receiving the pressure of filling layer material, and this local deformation can lead to appearing the gap between the adjacent separation portion, and leads to the filling material overflow. Illustratively, as shown in fig. 15, the rib 130 includes a main body portion 131 and branch portions 132, and the branch portions 132 are uniformly distributed on both sides of the main body portion 131 and symmetrically distributed with respect to the main body portion 131. One end of the main body part 131 is fixed on the fixing part 120, and the other end thereof is fixed on one end of the separation part 110 away from the fixing part 120 (which extends to the tip of the center of the valve body), while one end of the branch part 132 is fixed on the main body part 131, and the other end of the branch part 132 is fixed on the edge of the separation part 110, so that when the filling material is ready to overflow, the branch part 132 can provide a pulling force to the edge of the separation part 110, preventing the edge of the separation part 110 from being deformed to cause the overflow of the filling material.

In the embodiment of the present disclosure, the material of the valve (e.g., the separating portion, the fixing portion, the rib, etc. included in the valve) may be rubber, silicone, etc., and may be specifically selected according to the requirements of the actual process, which is not limited herein.

The first lead is connected with a male electrode in the electrical connector. The second lead is connected to a female electrode in the electrical connector. For example, one of the first and second wires is used to connect to an electronic device, and the other of the first and second wires is used to connect to an energy device such as a battery.
