Existing electrical connectors usually have corresponding protective structures to prevent water or impurities from entering the interior of the electrical connectors, to avoid short circuits or failures in the connectors, and to enable them to be used in various working conditions and environments with harsh use conditions, such as underwater live plugging and unplugging and other special working conditions. Existing electrical connectors have problems with sealing stability and sealing reliability, and are difficult to meet the requirements for sealing performance and safety performance of electrical connectors under special working conditions. Summary of the invention

[0003] The object of the present invention is to provide an electrical connector female end and an electrical connector assembly to solve the problem of poor sealing performance of the existing electrical connector.

[0004] The present invention is achieved through the following technical solutions: The female end of the electrical connector comprises a sealing member and a first conductor, wherein the sealing member is provided with a channel so that the first conductor arranged in the female end of the electrical connector can communicate with the outside only through the channel; It also includes a shut-off piece for applying an elastic force to the seal, which deforms under the action of the elastic force, so that the seal elastically deforms at the position where the elastic force acts and the channel is closed, and when the channel is closed, the first conductor can be isolated from the outside world.

[0005] In some embodiments, the first conductor is disposed within the seal and communicates with the channel.

[0006] In some embodiments, the first conductor is disposed in the female end of the electrical connector, and the second conductor of the male end of the electrical connector can be inserted through the passage and connected to the first conductor.

[0007] In some embodiments, when the second conductor of the male end of the electrical connector is inserted into the channel, the shut-off piece can be elastically deformed under the action of the second conductor, so that the shut-off piece moves in a direction opposite to the elastic force at the position acting on the sealing member.

[0008] In some embodiments, the shut-off member applies two elastic forces in opposite directions to the sealing member on both sides of the channel, so that the channel is closed at the position where the elastic forces act.

[0009] In some embodiments, the shut-off member applies an elastic force to the sealing member on one side of the channel, and utilizes a reverse force provided by a fixed wall on the other side of the channel to close the channel at the position where the elastic force acts.

[0010] In some embodiments, along the axial direction of the channel, the shut-off member is configured to exert elastic force on the sealing member at multiple positions, so that the channel is closed at multiple positions along the axial direction thereof.

[0011] In some embodiments, the seal is provided with a channel.

[0012] In some embodiments, the seal is tubular.

[0013] In some embodiments, a plurality of channels are disposed on the sealing member, and each channel is provided with a corresponding shut-off member for closing the corresponding channel.

[0014] In some embodiments, the sealing member is an elastic member made of non-metallic elastic material.

[0015] In some embodiments, an insulating member is further included. The insulating member is disposed at an end of the first conductor extending out of the sealing member, and is used to insulate and seal the end of the first conductor extending out of the sealing member.

[0016] On the other hand, in some embodiments, the female end of the electrical connector includes a tubular and elastic sealing member, a channel having an opening at least at one end is formed along the axial direction of the sealing member, a first conductor is arranged in the sealing member and the first conductor is connected to the channel; It also includes a shutoff member, which is used to apply two elastic forces in opposite directions to the sealing member on both sides of the channel, so that the channel is closed at the position where the elastic forces act; The position where the shut-off member applies force to the channel is located between the opening end of the channel and the first conductor.

[0017] On the other hand, in some embodiments, the female end of the electrical connector includes a tubular and elastic sealing member, a channel having an opening at least at one end is formed along the axial direction of the sealing member, a first conductor is arranged in the sealing member and the first conductor is connected to the channel; It also includes a shutoff member, which is used to apply an elastic force to the sealing member on one side of the channel, and use a reverse force provided by a fixed wall on the other side of the channel to close the channel at the position where the elastic force acts; The position where the shut-off member applies force to the channel is located between the opening end of the channel and the first conductor.

[0018] In another aspect, the present invention further provides an electrical connector assembly, comprising: The female end of the electrical connector; and an electrical connector male end, wherein the electrical connector male end includes a second conductor for connecting to the first conductor.

[0019] In some embodiments, the second conductor is covered with an insulating sleeve. When the second conductor is inserted into the channel, an interference fit is formed between the insulating sleeve and the seal, so that the first conductor can always be isolated from the outside world during the plugging and unplugging process of the second conductor through the cooperation between the insulating sleeve and the seal.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects: The present invention utilizes the shut-off member to exert an active elastic force on the seal, provides an active squeezing force on the seal, closes the channel of the seal, and can make the channel more tightly closed, so that the seal has better sealing performance.

[0021] Taking advantage of the fact that the shut-off piece can undergo elastic deformation, when the male end is inserted into the channel, the shut-off piece undergoes elastic deformation, and can provide the space required to accommodate the insertion of the male end in the channel while the channel is opened, thereby reducing the friction between the male end and the seal when the male end is inserted and removed, and can effectively reduce the wear on the channel when the male end is inserted and removed, and can well solve the problem of the existing passive extrusion structure that the channel is not tightly closed or cannot be effectively closed after the seal is worn.

[0022] The sealing method adopts the active squeezing of the sealing member by the shut-off member. When the male end is pulled out, the active squeezing force provided by the shut-off member can quickly close the channel, further improving the sealing effect and improving the stability and reliability of the seal.

[0023] In the present invention, the conductor of the female end of the electric connector is arranged in the sealing member, thereby improving the sealing performance of the female end of the electric connector and making the structure of the female end of the electric connector simpler.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] In the existing electrical connector sealing structure, a seal is set in the female end of the electrical connector, and the size difference between the inner volume of the female end shell and the volume of the seal is utilized. When the seal is installed in the shell, the seal is squeezed by the shell to close the channel on the seal, thereby sealing the interior of the electrical connector.

[0043] In this sealing structure that uses passive extrusion of the seal, when the male end of the electrical connector is inserted into the seal channel, the male end squeezes the seal again to open the channel. Since the space formed in the channel for accommodating the male end is provided entirely by the deformation of the seal, the seal is squeezed and deformed again on the basis of the original extrusion deformation, resulting in a large interaction force between the male end and the seal, which increases the friction between the male end and the seal. In this way, when the male end is repeatedly plugged in and out, it is easy to cause the inner wall of the seal channel to wear, resulting in the seal channel being unable to achieve effective closure under this passive extrusion force.

[0044] At the same time, this method of closing the channel of the seal by passive extrusion can only rely on the elastic deformation of the seal itself to close the channel when the male end is pulled out, resulting in slow channel closing speed and poor closing effect, all of which affect the sealing performance and effect of the electrical connector during actual use.

[0045] In addition, since the seals are usually made of non-metallic elastic materials such as silicone rubber, which are prone to wear and aging, the stability and reliability of the sealing performance of the electrical connector are difficult to guarantee and its service life is greatly limited if the seals rely solely on their own elastic deformation.

[0046] Through the above analysis of the problems existing in the existing sealing structure, it is found that in the existing sealing structure, although the deformation of the seal under the action of external force can close the channel and thus achieve a sealing effect, during the plugging and unplugging process, the opening and closing of the channel are achieved through the elastic deformation of the seal itself, which is the most fundamental reason for the above problems.

[0047] Based on the above findings, the present invention adopts a method of applying active elastic force to the seal to close the seal channel, which effectively solves the above problems.

[0048] Based on this technical idea, in some embodiments of the present invention, the female end 10 of the electrical connector includes a sealing member 102, and a channel 103 is provided on the sealing member 102, so that the first conductor 101 disposed in the female end of the electrical connector can only communicate with the outside through the channel. The second conductor 201 of the male end 20 of the electrical connector can be inserted into the female end of the electrical connector through the channel and form a connection with the first conductor.

[0049] That is to say, the seal provided on the female end of the electrical connector seals the electrical connector, sealing and isolating the first conductor in the female end of the electrical connector that transmits current from the outside world, and the second conductor at the male end of the connector can only enter the interior of the electrical connector through the channel.

[0050] In this embodiment, a shut-off piece 104 is provided at the female end 10 of the electrical connector to apply an active elastic force to the seal, so that the seal is deformed under the action of the elastic force, so that the seal is elastically deformed at the position where the elastic force acts and the channel can be closed. When the channel is closed, the first conductor can be isolated from the outside world, and the first conductor can be sealed in the female end of the electrical connector, thereby achieving sealed isolation of the first conductor.

[0051] As an operative method of the female end of the electrical connector, the first conductor may be disposed in the sealing member and connected to the channel, or the first conductor may be disposed in the female end of the electrical connector and the channel on the sealing member may be connected to the interior of the female end of the electrical connector, in which case the second conductor of the male end of the electrical connector may be inserted through the channel and connected to the first conductor. In this case, when the channel is closed by the shutoff member, the first conductor may be sealed and isolated from the outside.

[0052] In some embodiments, when the second conductor 201 of the male end 20 of the electrical connector is inserted into the channel 103, under the action of the second conductor, the second conductor applies a force on the shut-off piece that is opposite to the elastic force. Under this force, the shut-off piece can be elastically deformed, causing the shut-off piece to move in the direction opposite to the elastic force at the action position of the sealing piece, thereby providing the space required for the insertion of the second conductor.

[0053] In some embodiments, the sealing member 102 is in a tubular structure. The cross-sectional shape of the channel 103 on the sealing member 102 can match the cross-sectional shape of the second conductor of the male end 20 of the electrical connector, such as a circle or a rectangle.

[0054] The sealing member 102 may be made of silicone or similar elastic material.

[0055] In some embodiments, the structure of the shut-off piece 104 may be provided with two elastic arms 141, and the two elastic arms 141 constitute a structure similar to an elastic clip. The two elastic arms apply elastic forces in opposite directions to the seal on both sides of the channel, so that the channel is closed at the force position, isolating the first conductor from the outside world, thereby achieving a sealing effect.

[0056] In some embodiments, the shut-off member 104 may also have only one elastic arm 141. In this case, one side of the seal is pressed against a fixed member or a fixed wall. When the elastic arm applies an elastic force to the seal, the elastic force of the elastic arm and the force in the opposite direction provided by the fixed member or the fixed wall cause the seal to be elastically deformed, and the channel can also be closed at the position of the elastic force.

[0057] Of course, the shut-off piece is not limited to the above-mentioned method of using an elastic arm to apply an elastic force to the seal. For example, a combination of a spring and a slider can also be used. The spring provides the slider with a force that enables the slider to be pressed against the seal, actively squeezing the seal, which can also close the channel and achieve a sealing effect.

[0058] The force applied by the shut-off member to the seal can be adjusted by setting the elastic coefficient of the elastic arm or controlling the clamping depth of the elastic arm on the seal in a free state. Alternatively, the elastic arm can be limited at the clamping position to limit the clamping depth of the elastic arm on the seal, so as to control the clamping force of the shut-off member on the seal.

[0059] Based on the coordination between the shut-off piece and the seal and the force characteristics of the shut-off piece, when the second conductor at the male end of the electrical connector is inserted into the channel, the elastic arm can be elastically deformed. At this time, the accommodation space provided for the second conductor in the channel is provided by the deformation of the elastic arm and the deformation of the seal, thereby reducing the deformation of the seal and reducing the interaction force between the second conductor and the seal, thereby reducing the friction force between the second conductor and the seal during plugging and unplugging, which plays an important role in reducing the wear of the seal and can well solve the problem that the passive extrusion sealing method is prone to wear on the seal.

[0060] A more significant aspect is that, based on this active extrusion method, the channel of the seal can still be effectively closed even when the seal is worn, giving the electrical connector a clear advantage in sealing reliability and stability.

[0061] Also based on the characteristics of this active extrusion method, relying on the elastic force provided by the shut-off member, it also has obvious advantages in improving the reaction speed of the sealing channel closure.

[0062] In some embodiments, along the axial direction of the channel, the shutoff member 104 is configured to exert elastic force on the seal at multiple positions, so that the channel is closed at multiple positions along the axial direction thereof. It is easy to understand that by closing the channel at multiple positions, the sealing performance of the electrical connector can be further improved.

[0063] Taking the shut-off member structure that can simultaneously apply elastic forces in opposite directions to the seal on both sides of the channel as an example, two or more spaced clamping parts can be respectively provided on each elastic arm of the shut-off member, and these clamping parts can simultaneously provide clamping elastic forces to the seal at multiple positions of the seal, so that the channel is closed at multiple positions. Alternatively, multiple shut-off members are used to clamp the seal at different positions.

[0064] Usually, the position where the shut-off member acts on the sealing member can be arranged at a position close to the middle of the channel in the axial direction.

[0065] In some other embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 3 The female end 10 of the electrical connector includes a seal 102 and a first conductor 101. The seal is a tubular elastic member. A channel 103 is provided on the seal 102. The first conductor 101 is arranged in the seal and connected to the channel, so that the second conductor 201 of the male end 20 of the electrical connector can be inserted through the channel and connected to the first conductor.

[0066] Similarly, a shut-off piece 104 is provided to apply an elastic force to the sealing piece 102, wherein the position where the shut-off piece applies the force to the channel is between the opening end of the channel and the first conductor, and the sealing piece is deformed under the action of the elastic force, so that the channel 103 is closed at the position where the elastic force acts, thereby sealing the first conductor.

[0067] At this time, the first conductor 101 is sealed and wrapped in the sealing member 102, and the sealing member 102 and the first conductor 101 are matched to form a functional unit of the female end of the electrical connector, which can make the structure of the female end of the electrical connector simpler.

[0068] The first conductor 101 generally includes a crown spring nut and a crown spring disposed in the crown spring nut.

[0069] In some embodiments, when arranging the first conductor in the seal, an insulating member may be arranged at the end of the first conductor extending outside the seal, and the insulating member serves to insulate and seal the end of the first conductor extending outside the seal. Figure 3As shown, one end of the first conductor 101 can be set in an insulating member 107, and then the insulating member 107 is set in the channel 103 of the sealing member 102. The insulating member covers one end of the first conductor, and then the sealing member covers the insulating member. The three are closely matched, which can achieve a good sealing and insulation effect between the first conductor at this end and the outside world. Of course, a sealing process can be further performed between the first conductor and the insulating member to better seal the end of the first conductor exposed from the sealing member.

[0070] At this time, interference fit connection can be adopted between the first conductor and the insulating member, and between the insulating member and the channel of the sealing member.

[0071] The female end of the electrical connector with this structure can optimize the number of required components, making the female end of the electrical connector simpler in structure and having better reliability.

[0072] In some embodiments, taking the female end of an electrical connector having two jacks as an example, referring to Figure 4 , Figure 5 , Figure 6 and Figure 7 The female end 10 of the electrical connector can adopt two groups of functional units formed by a seal and a first conductor, in which the first conductor is arranged in the seal, and the two groups of functional units are arranged side by side in the electrical connector. A channel is arranged on the seal of the functional unit, and the channel corresponds to the first conductor.

[0073] At this time, the closing piece 104 can adopt a structure formed by two groups of elastic arm assemblies, each group of elastic arm assemblies includes two elastic arms 141 arranged relatively on both sides of the seal, and the two groups of elastic arm assemblies are arranged side by side at positions corresponding to the two seals, for respectively providing the two seals with the elastic force required to close the channel.

[0074] As a concrete way to implement it, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the female end 10 of the electrical connector includes a housing 105 and a base 106 disposed in the housing. Two holes for arranging the above two groups of functional units are arranged side by side on the base 106 , and the two groups of functional units are respectively arranged in the base 106 .

[0075] The shutoff member 104 includes a fixing portion, and the elastic arms 141 are connected to the fixing portions at one end, and the shutoff member 104 is connected to the base 106 via the fixing portion. A notch is provided on the base 106, so that both sides of the sealing member 102 can be exposed from the notch position; accordingly, the free ends of the elastic arms of the shutoff member 104 are respectively extended into the notch, and the two elastic arms arranged opposite to each other can clamp the sealing member to close the channel of the sealing member.

[0076] The female end 10 of the electrical connector may also use only one sealing member 102, on which two parallel channels 103 are provided, as shown in FIG. Fig.11 , the two first conductors 101 are both arranged in the sealing member and correspond to the two channels respectively. Accordingly, each channel is provided with a corresponding shutoff member for closing the corresponding channel; or the elastic arms of the two shutoff members arranged side by side are arranged as an integral structure. In this case, the shutoff members provide the sealing member with the elastic force required to close the channels at the two channel positions respectively, and an electrical connector female end with two jacks can also be obtained.

[0077] Based on the same working principle, the above structure is also applicable to other female ends of electrical connectors with various numbers of jacks.

[0078] In some embodiments, taking the female end of the electrical connector having two jacks as an example, referring to Figure 8 , Fig. 9 and Fig.10 , the female end 10 of the electrical connector adopts two groups of functional units formed by sealing members and first conductors. Different from the above-mentioned embodiments, one side of the sealing members of the two groups of functional units respectively abuts against a fixing member or a fixing wall, for example, one side of the sealing member abuts against the shell or the base, and at this time, the shut-off member adopts a structure with two elastic arms, the two elastic arms are arranged oppositely or side by side, and are respectively arranged at positions corresponding to the two sealing members, and each elastic arm applies an elastic force to the corresponding sealing member, and at this time, under the action of the elastic arm and the fixing member or the fixing wall, the channel of the sealing member at the corresponding position can be closed at the elastic force action position through one elastic arm.

[0079] Reference Figure 8 A limit portion 1061 can be set on the base 106, and the limit portion is correspondingly arranged at the position where the elastic arm applies force to the seal and is located on the other two sides of the seal. When the working end of the elastic arm clamps the seal, the limit portion can limit the clamping depth of the working end of the elastic arm, thereby controlling the clamping force of the elastic arm.

[0080] Reference Fig.12 , Fig.13 , are two other feasible structural forms, in which two sealing members arranged side by side are used as a group of sealing components, one side of the sealing component is against the base, and the other side is provided with an elastic force for the two sealing members by a shut-off member having an integral elastic arm or two elastic arms arranged side by side; another group of sealing components and shut-off members can be arranged on the opposite side of the base, and an electrical connector female end with four jacks can be obtained.

[0081] On the other hand, in some embodiments of the present invention, referring to Fig.14and Fig.15 The electrical connector assembly includes an electrical connector male end 20 and an electrical connector female end 10 using the above embodiment. The electrical connector male end 20 has a second conductor 201, and the electrical connection between the male end and the female end is achieved through the connection between the first conductor and the second conductor.

[0082] As mentioned above, generally, the cross-section of the second conductor 201 is set to be the same as the cross-section of the channel on the seal, and the sizes of the two are matched, so that a good sealing fit can be formed between the second conductor and the seal, while reducing the friction between the second conductor and the seal during the plugging and unplugging process, thereby reducing the wear on the seal.

[0083] An insulating sleeve 202 can be covered on the second conductor 201. While the insulating sleeve is insulated, there is an interference fit between the insulating sleeve and the channel of the sealing member, and a good sealing fit can be formed between the insulating sleeve and the sealing member. During the plugging and unplugging process of the second conductor, the cooperation between the insulating sleeve and the sealing member can always isolate the first conductor from the outside world, thereby further increasing the sealing during the plugging and unplugging process of the male end and the female end.
