[0074] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0075] like Figures 1 to 7 As shown, the utility model provides an electrical connector, an electrical connector assembly 100, an electrical device (not shown) and a vehicle (not shown). Among them, the electrical connector can be one of a first electrical connector 110 and a second electrical connector 130. The first electrical connector 110 can be understood as a movable electrical connector for connecting to a cable or a wire, such as an electrical plug. The first electrical connector 110 and can be called a line-end electrical connector. The second electrical connector 130 can be understood as an electrical connector fixed to a corresponding object and connected to the electrical structure inside the object, such as an electrical socket. The second electrical connector 130 is usually unable to be moved in at least one direction relative to the object in a natural state. The natural state here can be understood as a state in which the second electrical connector 130 is not removed from the object. The second electrical connector 130 can also be called a board-end electrical connector. The electrical connector assembly 100 includes a first electrical connector 110 and a second electrical connector 130. The first electrical connector 110 and the second electrical connector 130 are connected by plugging. The electrical device and the vehicle each include an electrical connector assembly 100.

[0076] The following will refer to Figures 1 to 7 The illustrated embodiments describe in detail the electrical connector, electrical connector assembly, electrical equipment and vehicle according to the present invention. The electrical connector may be a first electrical connector 110 or a second electrical connector 130. The electrical connector will be described in detail below by taking the first electrical connector 110 as an example.

[0077] According to an embodiment of the present invention, the first electrical connector 110 may include a first electrical terminal 111, an insulating sheath 101, and an anti-touch finger member 114. A first cavity 110a is formed inside the insulating sheath 101. The first cavity 110a accommodates the first electrical terminal 111. The insulating sheath 101 has a first end 101a (eg, Figure 3 as shown) and the second end 101b (as shown Figure 3 As shown). A first through hole 112a is formed at the first end 101a of the insulating sheath 101 along the first direction D1. The first through hole 112a is connected to the first cavity 110a. The first through hole 112a is suitable for plugging another electrical connector. Here, the “other electrical connector” is the second electrical connector 130.

[0078] The anti-touch finger 114 is connected to the insulating sheath 101. At least part of the anti-touch finger 114 extends in the first cavity 110a along the first direction D1. The anti-touch finger 114 is spaced apart from the first electrical terminal 111. The anti-touch finger 114 is closer to the first end 101a than the first electrical terminal 111 in the first direction D1.

[0079] According to the first electrical connector 110 of the embodiment of the utility model, the first electrical terminal 111 is accommodated by the insulating sheath 101, the anti-touch finger 114 is installed in the first cavity of the insulating sheath 101, and the anti-touch finger 114 is separated from the first electrical terminal 111. Therefore, the utility model can reduce the influence of the heat generated by the first electrical terminal 111 on the anti-touch finger 114, thereby reducing or avoiding the risk of the anti-touch finger 114 being loosened due to high temperature, thereby improving the reliability of the anti-touch finger 114 and the service life of the first electrical connector 110.

[0080] See also Figures 2 to 7For example, the anti-touch finger 114 may include an anti-touch base 114a and an anti-touch pin 114e. The anti-touch base 114a is connected to the second end 101b of the insulating sheath 101 along the first direction D1. The anti-touch pin 114e is connected to the anti-touch base 114a. The anti-touch pin 114e extends at least to the first cavity 110a along the first direction D1. The anti-touch pin 114e is closer to the first end 101a than the first electrical terminal 111 in the first direction D1. That is, the anti-touch pin 114e exceeds the end of the first electrical terminal 111 close to the first end 101a in the first direction D1. Here, the function of preventing human hands from touching the first electrical terminal 111 is achieved by connecting the anti-touch base 114a of the anti-touch finger 114 to the second end 101b of the insulating sheath 101 and extending the anti-touch pin 114e in the first cavity 110a along the first direction D1. This makes the functional division of each part of the anti-touch finger 114 clearer, and facilitates the design of the corresponding parts according to actual conditions. Among them, the anti-touch pin 114e can be understood as a needle-shaped long strip structure. When applied to a first electrical terminal with a hole, the anti-touch pin 114e can be passed through the hole of the first electrical terminal to improve space utilization and structural compactness.

[0081] Continue reading Figures 2 to 7 For example, the anti-touch base 114a is located outside the insulating sheath 101. In a plane perpendicular to the first direction D1, the area of ​​the orthographic projection of the anti-touch base 114a is greater than the area of ​​the orthographic projection of the anti-touch pin 114e. In this way, the anti-touch base 114a can serve as a limiting structure of the anti-touch finger 114 to limit the insertion depth of the anti-touch pin 114e in the insulating sheath 101 in the first direction D1. The anti-touch base 114a may include a heat dissipation hole 114d that is arranged along the first direction D1. The heat dissipation hole 114d is provided to facilitate heat dissipation of the insulating sheath 101.

[0082] See also Figures 2 to 7 , further, a heat-conducting protrusion 113b is formed on the second end 101b of the insulating sheath 101. The heat-conducting protrusion 113b is inserted into the heat-dissipating hole 114d. By setting the heat-conducting protrusion 113b to be inserted into the heat-dissipating hole 114d, on the one hand, the heat dissipation area of ​​the insulating sheath 101 is increased, and on the other hand, the heat of the insulating sheath 101 can be conducted outward faster to improve the heat dissipation efficiency. The anti-touch finger member 114 of one embodiment of the utility model can be constructed as an insulating member made of plastic or plastic. The surface of the anti-touch finger member 114 of the utility model increases the heat dissipation hole 114d, and the surface area of ​​the second sheath 113 is increased by setting the heat-conducting protrusion 113b, and the heat-conducting protrusion 113b is inserted into the heat-dissipating hole 114d, thereby improving the heat dissipation effect, reducing the aging of the plastic, and increasing the service life.

[0083] The anti-touch finger member 114 provided in another embodiment of the present invention can also be configured as follows: the anti-touch base 114a is an insulating member made of plastic or plastic, the anti-touch pin 114e is a metal member, the anti-touch base 114a and the anti-touch pin 114e are injection-molded together, and an anti-touch cap made of plastic or plastic material is installed at the end of the anti-touch pin 114e close to the first end 101a, and the anti-touch cap and the anti-touch pin can be snapped together.

[0084] Another embodiment of the present invention provides an anti-touch finger 114 that can also be configured as follows: the anti-touch base 114a is a metal piece, the anti-touch pin 114e is an insulating piece made of plastic or plastic, and the anti-touch base 114a and the anti-touch pin 114e are connected together by bonding or other means.

[0085] Optionally, the insulating sheath 101 is a ceramic sheath. The ceramic sheath is an insulating sheath 101 made of ceramic material. Compared with insulating materials such as plastic, the ceramic sheath has better thermal conductivity. The outer surface of the first electrical terminal 111 is attached to the insulating sheath 101. In this way, the heat dissipation efficiency of the first electrical terminal is improved, and the reliability and safety of the first electrical connector 110 are improved.

[0086] See also Figures 1 to 7For example, the insulating sheath 101 may include a first sheath 112 and a second sheath 113 that are arranged opposite to each other. Here, the first sheath 112 corresponds to the first end 101a of the insulating sheath 101, and the second sheath 113 corresponds to the second end 101b of the insulating sheath 101. The first sheath 112 is configured as a component made of ceramic. The first via 112a is arranged to penetrate the first sheath 112 along the first direction D1. The second sheath 113 is configured as a component made of ceramic. The second sheath 113 is detachably connected to the first sheath 112. The second sheath 113 and the first sheath 112 are enclosed to form the above-mentioned first cavity 110a. The second sheath 113 has a second via 113a that is arranged to penetrate along the first direction D1. The second via 113a is connected to the first cavity 110a. The second via 113a is arranged opposite to the first via 112a in the first direction D1. The outer surface of the first electrical terminal 111 is attached to the first sheath 112 and the second sheath 113. The first electrical terminal 111 has a plug hole 111a that is arranged through. The first through hole 112a, the plug hole 111a and the second through hole 113a are arranged in sequence along the first direction D1. The anti-touch base 114a is attached to the surface of the second sheath 113 away from the first sheath 112 along the first direction D1. The anti-touch base 114a is detachably connected to the first sheath 112, and the second sheath 113 is clamped between the first sheath 112 and the anti-touch base 114a in the first direction D1, so that the first sheath 112 is connected to the second sheath 113. The anti-touch pin 114e is inserted through the second through hole 113a and the plug hole 111a. The anti-touch pin 114e is spaced apart from the first electrical terminal 111 in the radial direction of the plug hole 111a. Optionally, the anti-touch pin 114e is spaced apart from the second sheath 113 in the radial direction of the plug hole 111a. The aforementioned heat-conducting protrusion 113 b is disposed on the second sheath 113 .

[0087] According to the first electrical connector 110 of the utility model, since the first sheath 112 and the second sheath 113 are separable, they are easy to manufacture, assemble and replace separately. The first sheath 112 and the second sheath 113 are attached to the first electrical terminal 111, and the anti-touch finger 114 is attached to the second sheath 113. In this way, heat conduction can be achieved by directly contacting the first electrical terminal 111 through the first sheath 112 and the second sheath 113, and the anti-touch finger 114 is not directly connected to the first electrical terminal 111, thereby reducing the impact of the heat generated by the first electrical terminal 111 on the anti-touch finger 114, and thus preventing the anti-touch finger 114 from loosening due to high temperature. In short, the anti-touch finger 114 of the utility model is attached to the second sheath 113, and the anti-touch finger 114 is fixed to the first sheath 112, not directly fixed to the terminal, and is less affected by the heat generated by the terminal, and there is no risk of detachment due to high temperature. In addition, the above technical means make the installation and disassembly of the first electrical connector 110 and the anti-touch finger member 114 more convenient, and the manufacturing cost is low.

[0088] See also Figure 2 , Figure 3 as well as Figure 5 Optionally, the diameter of the first via hole 112a is larger than the diameter of the second via hole 113a. When the anti-touch pin 114e is inserted into the first via hole 112a, the second via hole 113a and the plug hole 111a, the anti-touch pin 114e is spaced apart from the hole wall of the plug hole 111a. In this way, on the one hand, the anti-touch pin 114e can prevent a human hand from contacting the first electrical terminal 111, and on the other hand, the anti-touch pin 114e does not directly contact the first electrical terminal 111.

[0089] See also Figures 2 to 7 For example, the anti-touch base 114a is snap-connected to the first sheath 112. By using the snap-connection method to connect the anti-touch base 114a to the first sheath 112, the assembly operation is simple and convenient. The anti-touch finger 114 of the utility model is fixed to the first sheath 112 by snap-connection, and the fixing method is firm, serving as a fixing structure of the open-close sheath. The open-close sheath here includes the first sheath 112 and the second sheath 113.

[0090] See also Figures 3 to 6 Specifically, a first clamping hole 112b is provided on the outside of the first sheath 112. The anti-touch base 114a includes a first elastic clamping foot 114b. The first elastic clamping foot 114b is snap-connected to the first clamping hole 112b to connect the anti-touch base 114a to the first sheath 112. In the case where the first sheath 112 is made of ceramic, it is not suitable to make the elastic clamping foot. Therefore, by providing the first clamping hole 112b on the first sheath 112 to cooperate with the first elastic clamping foot 114b provided on the anti-touch base 114a, a snap connection is achieved. In this way, the assembly requirements of the ceramic first sheath 112 and the anti-touch base 114a can be met.

[0091] exist Figures 3 to 6 In the example shown, the first sheath 112 may include two first clamping holes 112b. The two first clamping holes 112b are located at two opposite sides of the first sheath 112 along the third direction D3. The anti-touch base 114a may include two first elastic clamping feet 114b. The two first elastic clamping feet 114b are located at two opposite sides of the anti-touch base 114a.

[0092] Continue reading Figures 2 to 7Further, a first receiving groove 112c is formed on the end face of the first sheath 112 along the first direction D1. The first receiving groove 112c is located on the end face of the first sheath 112 close to the second sheath 113. The first receiving groove 112c is suitable for accommodating part of the second sheath 113. For example, the first receiving groove 112c is suitable for accommodating an end of the second sheath 113 close to the first sheath 112. The second sheath 113 located in the first receiving groove 112c is limitedly matched with the first sheath 112 at the intersection of the first direction D1. That is, the first sheath 112 and the second sheath 113 are partially nested. This facilitates the positioning of the first sheath 112 and the second sheath 113 with each other, and is also conducive to improving the structural compactness of the combination of the first sheath 112 and the second sheath 113 in the first direction D1.

[0093] See also Figures 2 to 7 Furthermore, the second housing 113 is recessed at the end surface away from the first housing 112 in the first direction D1 to form a second receiving groove 113c. The second receiving groove 113c is located at the end surface of the second housing 113 away from the first housing 112. The second receiving groove 113c is suitable for accommodating the anti-touch base 114a. The anti-touch base 114a located at the second receiving groove 113c can be selectively set in the first direction D1 not to exceed the end surface of the second housing 113 away from the first housing 112 in the first direction D1. In this way, the second housing 113 and the anti-touch finger 114 are compact in the first direction D1, and at the same time, it helps to further increase the heat dissipation area of ​​the second housing 113.

[0094] See also Figure 2 Optionally, the anti-touch base 114a and the anti-touch pin 114e are constructed as an integrated component, which can reduce the number of parts, simplify the assembly process, and improve assembly efficiency.

[0095] See also Figure 2 Optionally, the free end of the anti-touch pin 114e protrudes from the end of the plug hole 111a away from the anti-touch base 114a. This can better prevent the operator's hand from contacting the first electrical terminal 111, thereby improving safety.

[0096] See also Figures 1 to 5 as well as Figure 7For example, the first sheath 112 has a head end and a tail end opposite to each other along the second direction D2. The head end here is an end arranged corresponding to the first electrical terminal 111, and the tail end is an end away from the first electrical terminal in the second direction D2. The same is true for the head end of the second sheath 113 and the head end of the shielding shell 115. The second direction D2 intersects with the first direction D1, for example, vertically. The first via 112a is located at the head end of the first sheath 112. The second via 113a is located at the head end of the second sheath 113. The head end of the first sheath 112 and the head end of the second sheath 113 are arranged opposite to each other. The first via 112a and the second via 113a are aligned along the first direction D1. The tail end of the first sheath 112 and the tail end of the second sheath 113 are enclosed to form a third via 110b. The depth direction of the third via 110b is parallel to or nearly parallel to the second direction D2. The third via 110b is connected to the first cavity 110a. The third through hole 110b is suitable for passing a cable, and can also pass a portion of the first electrical terminal 111 for connecting a cable, so as to ensure that the first electrical terminal 111 is completely located between the first sheath 112 and the second sheath 113, and the first electrical terminal 111 can be contacted and positioned by the first sheath 112 and the second sheath 113, thereby better preventing the first electrical terminal 111 from directly contacting the anti-touch finger 114.

[0097] See also Figures 1 to 7 In addition, the first electrical connector 110 may further include a shielding shell 115. A second cavity 115b is formed inside the shielding shell 115.

[0098] See also Figures 2 to 7For example, the anti-touch base 114a is snap-connected to the shielding shell 115. This facilitates the assembly of the insulating sheath, the first electrical terminal 111, and the anti-touch finger 114 in the shielding shell 115, and also prevents the anti-touch base 114a from being separated from the shielding shell 115 to a certain extent. When the first electrical terminal is connected to the cable, it also helps to enhance the anti-pulling performance between the cable and the shielding shell.

[0099] See also Figure 7 , further, the inner wall of the shielding shell 115 is provided with a second clamping hole 115a. The anti-touch base 114a includes a second elastic clamping foot. The second elastic clamping foot is buckled and connected to the second clamping hole 115a to connect the anti-touch base 114a to the shielding shell 115. When the second elastic clamping foot is clamped into the second clamping hole 115a, the anti-touch finger 114 can be prevented from withdrawing from the second cavity 115b, thereby improving the stability of the connection structure between the combination of the first sheath 112, the second sheath 113, the first electrical terminal 111 and the anti-touch finger 114 and the shielding shell 115. The anti-touch finger 114 of the utility model adopts a second elastic clamping foot 114c, which can be matched with the second clamping hole 115a on the shielding shell 115 to position and fix the first sheath 112 and the second sheath 113 on the shielding shell 115.

That is, one end of the shielding ring 117 is sleeved outside the tail end of the insulating sheath 101. The shielding ring 117 is connected to the fifth via 115d. By providing the shielding ring 117, the anti-electromagnetic interference performance of the first electrical terminal 111 can be enhanced.

[0101] Continue reading Figures 1 to 7 For example, the portion of the shielding ring 117 close to the sixth via 117b extends in a direction parallel to the center line of the sixth via 117b to form a crimping portion 117a. That is, the other end of the shielding ring 117 is configured as the crimping portion 117a. The first electrical connector 110 may further include a crimping ring 118. The crimping ring 118 is crimped on the outside of the crimping portion 117a so that the shielding ring 117 is fixed to the cable 116.

[0102] See also Figures 2 to 7In addition, the first electrical connector 110 may further include a sealing ring 119 and a tail cover 121. The sealing ring 119 is disposed in the second cavity 115b of the shielding shell 115. The sealing ring 119 is sleeved on the outside of the cable 116. The inner circumference of the sealing ring 119 is sealed with the cable 116. The sealing ring 119 is sealed to the fifth through hole 115d. The tail cover 121 is snap-connected to the shielding shell 115 at the fifth through hole 115d. The sealing ring 119 is located between the tail cover 121 and the shielding ring 117. By adding the sealing ring 119, the sealing between the cable 116 and the shielding shell 115 can be improved, and the first seal can be achieved. By adding the tail cover 121, the shielding ring 117, the first sheath 112, the second sheath 113, the first electrical terminal 111, and the anti-touch finger 114 and other components can be covered. The tail cover 121 is snap-connected to the shielding shell 115, and the assembly is more convenient.
