The electronic components can be resistors, capacitors, or integrated circuits, which are not limited in this application. The wiring harness assemblies are connected between the electronic components to form a current path between the electronic components, thereby realizing information exchange between the electronic components.
[0084] Please refer to Figure 1 The wiring harness assembly 3000 includes a wiring harness and a connector assembly 1000. The wiring harness is used to connect the electronic components to form a current path between the electronic components. The wiring harness can be a cable used only to transmit current, or a signal bus used to transmit signals. When the wiring harness is a signal bus, the wiring harness can be a CAN line, a LIN line, or a MOST line, and this application does not limit this. The wiring harness has at least two wiring harness terminals 2000. The two wiring harness terminals 2000 can be distributed on the same wiring harness or on different wiring harnesses, and this application does not limit this.
[0085] The connector assembly 1000 is used to realize the connection of different wiring harness terminals 2000. Specifically, the connector assembly 1000 includes a connector body 4 and a cover body 1. The connector body 4 is provided with at least two wiring ports 42. The wiring harness terminal 2000 can be inserted into the connector body 4 through the wiring ports 42 and complete the connection in the connector body 4. When the wiring harness terminal 2000 is connected, in order to ensure the stability of the connection of the wiring harness terminal 2000, the wiring harness terminal 2000 inserted into the connector body 4 is usually fixed by a bolt 5. At the same time, in order to ensure that the bolt 5 can complete the connection with the wiring harness terminal 2000 in the connector body 4, the connector body 4 is usually provided with an opening 41, and the opening 41 is used for the bolt 5 and the installation tool to be inserted.
[0086] The cover body 1 is used to cover the opening 41 to form a seal at the opening 41. For details, please refer to Figure 1 , Figure 15a is a schematic diagram of the position of the bolt 5 when it is not assembled with the harness terminal 2000, 5b is a schematic diagram of the position of the bolt 5 when it is assembled with the harness terminal 2000, 1a is a schematic diagram of the position of the cover 1 when it is not covered with the opening 41, and 1b is a schematic diagram of the position of the cover 1 when it is covered with the opening 41. In the related art, the cover 1 is usually made of plastic material, which has poor electromagnetic shielding ability and cannot meet the requirements of high electromagnetic shielding.
[0087] Please refer to Figure 2 In order to solve the above problems, in the present application, the connector assembly 1000 further includes a shielding member 2, which is arranged on the cover 1, and the shielding member 2 and the connector body 4 are surrounded to form a shielding space, and the shielding space is used to accommodate the wiring harness terminal 2000. The technical solution of the present application is to arrange the shielding member 2 in the connector assembly 1000, and to form a shielding space by the shielding member 2 and the connector body 4, and the wiring harness terminal 2000 of the wiring harness is accommodated in the shielding space, so as to reduce the influence of external electromagnetic waves on the wiring harness terminal 2000, and improve the electromagnetic shielding capability of the connector assembly 1000.
[0088] Hereinafter, the connector assembly 1000 provided in the present application will be described in detail with reference to the accompanying drawings.
[0089] Please refer to Figure 3 The connector assembly 1000 includes a connector body 4, a cover body 1 and a shielding member 2. The connector body 4 is the main component of the connector assembly 1000 and is used to support and connect the various parts of the connector assembly 1000. The connector body 4 is made of metal. A wiring cavity is formed in the connector body 4. The outer wall surface of the connector body 4 is provided with a wiring port 42 connected to the wiring cavity. The wiring harness terminal 2000 of the wiring harness can be extended into the wiring cavity through the wiring port 42 for connection. The connector body 4 is also provided with an opening 41, and the opening 41 is used for the bolt 5 to extend into, so as to connect the wiring harness terminal 2000 in the wiring cavity.
[0090] Please refer to Figure 4 The inner wall surface of the opening 41 of the connector body 4 is provided with a plurality of snap-fitting bosses 43, which are used to cooperate with the cover body 1 to lock the cover body 1 at the opening 41 of the connector body 4. At the same time, the opening 41 of the connector body 4 is also provided with a snap-fit 44, a first snap-fitting slot 45 and a second snap-fitting slot 47, which are sequentially arranged along the circumference of the connector body 4, and the snap-fit 44, the first snap-fitting slot 45 and the second snap-fitting slot 47 are used to cooperate with the cover body 1 and the shielding member 2, so as to lock the circumferential rotation of the cover body 1 when the cover body 1 is in a tightened state, thereby fixing the cover body 1 at the opening 41. The specific cooperation method of the snap-fit 44, the first snap-fitting slot 45 and the second snap-fitting slot 47 with the shielding member 2 can be seen later.
[0091] Please refer to Figure 5 and Figure 6 The cover 1 is disposed on the opening 41 to prevent external impurities or water vapor from entering the wiring cavity through the opening 41, thereby protecting the electrical safety of the wiring harness terminal 2000 in the wiring cavity. The cover 1 can be made of polypropylene (PP), polyethylene (PE), or thermoplastic polyester (PET), and this application does not limit this.
[0092] The cover body 1 has a tightened state and an unscrewed state. When the cover body 1 is in the unscrewed state, the cover body 1 can freely enter and exit the opening 41 of the connector body 4. When the cover body 1 is in the tightened state, the cover body 1 is locked in the opening 41 of the connector body 4.
[0093] In order to realize the tightening and loosening of the cover body 1 on the opening 41, the cover body 1 includes a cover body 11 and a plurality of buckles 13 arranged along the circumference of the cover body 11, and the number of the buckles 13 is arranged in a one-to-one correspondence with the number of the clamping bosses 43. When the cover body 1 is assembled with the connector body 4, the buckle 13 can slide into the opening 41 along with the cover body 11, and the buckle 13 can pass through the gap between the clamping bosses 43 to reach the bottom of the clamping bosses 43. When the cover body 1 is in the loosening state, the buckle 13 and the clamping bosses 43 are arranged in a staggered manner, and the cover body 11 can slide freely along the axis of the opening 41. If the cover body 11 is rotated at this time, the cover body 1 can be switched from the loosening state to the tightening state. In the tightening state, the buckle 13 and the clamping bosses 43 are arranged in a counterposition, and the buckle 13 contacts the clamping bosses 43 on the side facing the opening 41, so that the buckle 13 is restricted from moving in the direction of the opening 41, thereby fixing the cover body 1 in the opening 41. Compared with other fixing methods such as threaded fixing of the cover 1 and the connector body 4, the cover 1 fixed with the buckle 13 has a longer service life because the buckle 13 does not produce friction with the inner wall of the opening 41. Compared with bolt fixing, the cover 1 fixed with the buckle 13 occupies less space for the connector assembly 1000, has higher space utilization, lower cost, higher assembly efficiency, is not easy to loosen, and has high connection reliability.
[0094] The number of the pull buckles 13 and the snap-on bosses 43 can be two, three, or four, and the present application does not limit this. For example, in one embodiment of the present application, the pull buckles 13 are provided in three numbers and are evenly distributed along the circumference of the cover body 11, and correspondingly, the snap-on bosses 43 are provided in three numbers and are evenly distributed along the circumference of the inner wall of the opening 41, so as to balance the force on the cover body 1 and improve the stability of the fixation between the cover body 1 and the connector body 4.
[0095] In order to facilitate the tightening of the cover body 11, a tightening hole 111 is provided on the side of the cover body 11 away from the opening 41, and an operating tool can be inserted into the tightening hole 111 to tighten or loosen the cover body 11. The tightening hole 111 is in a triangular, trapezoidal or special shape, so as to increase the complexity of the operating tool for opening the cover body 1, prevent the cover body 1 from being easily opened, and improve the safety of the connector assembly 1000.
[0096] Please refer to Figure 7 The connector assembly 1000 also includes a shielding member 2, which is disposed on the cover body 1. The arrangement of the shielding member 2 can, on the one hand, form a support for the cover body 1, thereby improving the support strength of the cover body 1. On the other hand, the shielding member 2 can be formed with the wiring cavity of the connector body 4 to form a shielding space, and the shielding space can shield electromagnetic waves, thereby improving the electromagnetic shielding capability of the cover body 1. The material of the shielding member 2 can be metal, conductive fiber material, or an electrical conductor or good conductor such as graphene. The purpose is to form a "Faraday cage" in the shielding space to isolate the charged body in the shielding space from interference from external electromagnetic waves. This application does not impose any restrictions on this.
[0097] The shielding component 2 and the cover body 1 can be connected by bonding or by hot pressing. In one embodiment of the present application, the shielding component 2 is integrally formed with the cover body 1 through a molding process. In this way, the stability of the connection between the shielding component 2 and the cover body 1 is ensured, the connection process between the shielding component 2 and the cover body 1 is simplified, and the manufacturing efficiency of the cover body 1 is improved.
[0098] In one possible implementation mode of the present application, along the axial direction of the cover body 1, the projection of the cover body 1 is located within the projection of the shielding member 2, so that the shielding member 2 completely covers the opening 41, forming a more effective shielding space with the connector body, thereby improving the electromagnetic shielding capability of the connector.
[0099] Please refer to Figure 8 The shielding member 2 includes a main body 21, and a surface of the main body 21 is provided with a plurality of through holes 212 penetrating along the thickness thereof, and the cover body 1 at least partially extends into the through holes 212, so as to increase the contact area between the cover body 1 and the shielding member 2 and improve the connection strength between the shielding member 2 and the cover body 1.
[0100] Please refer to Fig. 9 The shielding member 2 is also used to cooperate with the connector body 4 to lock the cover body 1 in the circumferential rotation at the opening. There are many ways for the shielding member 2 to cooperate with the connector body 4 to lock the cover body 1. In one embodiment of the present application, the bayonet 44 is provided with a stop surface 441a on the side close to the first slot 45, and the outer edge of the body 21 of the shielding member 2 is also provided with a protrusion 22, and the protrusion 22 has a contact surface 221a. The edge of the cover body 11 is provided with a limit platform 12.
[0101] When the cover 1 is in the unscrewed state, the protrusion 22 is located in the first slot 45 , the limiting platform 12 is located in the second slot 47 , and the limiting platform 12 is not in contact with the wall surface of the second slot 47 close to the first slot 45 .
[0102] When the cover body 11 rotates (the cover body 11 can rotate clockwise or counterclockwise. For the sake of ease of description, it is assumed that the second card slot 47, the first card slot 45 and the bayonet 44 are arranged counterclockwise along the circumference of the connector body 4, and the cover body 11 rotates counterclockwise), the protrusion 22 can slide along the first card slot 45 driven by the cover body 11, and the first card slot 45 is used to provide guidance for the movement of the protrusion 22.
[0103] Please refer to Fig.10 During the rotation of the cover body 11, the stopper 12 contacts the wall of the second slot 47 near the first slot 45, and prevents the cover body 11 from continuing to rotate in the counterclockwise direction. At the same time, the protrusion 22 will be separated from the first slot 45 and enter the bayonet 44. When the protrusion 22 is located in the bayonet 44, the abutment surface 221a of the protrusion 22 contacts the stopper surface 441a of the bayonet 44, and the rotation of the cover body 11 in the clockwise direction is also prevented. The cover body 1 is switched from the loose state to the tight state, and the cover body 11 is locked in the opening. At this time, if the cover body 1 is to be switched back to the loose state, a tool needs to be inserted into the bayonet 44, radially pressing the protrusion 22 to force the deformation groove on the shielding member 2 to deform, and at the same time, the cover body 11 is twisted clockwise with a special tool, and the protrusion 22 bypasses the push block 46 and returns to the first slot 45, thereby achieving the loosening of the cover body 1.
[0104] In order to cooperate with the protrusion 22 to slide into the bayonet 44, the connector body 4 is further provided with a push block 46, which separates the first slot 45 and the bayonet 44. The push block 46 is used to press the protrusion 22 when the protrusion 22 slides from the first slot 45 into the bayonet 44, and push the protrusion 22 to deform toward one side of the body, so that the protrusion 22 can be separated from the first slot 45 and enter the bayonet 44.
[0105] In one embodiment of the present application, a chamfer 461 is provided on the side of the push block 46 facing the first slot 45. The chamfer 461 is used to reduce the resistance of the protrusion 22 over the push block when the cover body 1 is screwed from a loose state to a tight state, thereby improving the smoothness of the protrusion 22 sliding into the slot 44 and reducing the difficulty of tightening the cover body 1.
[0106] In order to further reduce the resistance of the protrusion 22 entering the bayonet 44, in one embodiment of the present application, a deformation groove 211 is provided on one side of the body 21 close to the protrusion 22, and the deformation groove 211 is spaced apart from the protrusion 22. When the protrusion 22 is pushed toward the side of the cover body 1 by the push block 46, the deformation groove 211 can leave space for the deformation of the protrusion 22, thereby increasing the deformation degree of the protrusion 22, reducing the difficulty of the protrusion 22 sliding into the bayonet 44, and improving the assembly efficiency of the cover body 1 and the connector body 4.
[0107] In one possible implementation mode of the present application, the deformation groove 211 is extended along the circumference of the main body 21, so that the extension direction of the deformation groove 211 is consistent with the rotation direction of the cover body 1, thereby balancing the force on the deformation groove 211 and improving the deformation capacity of the deformation groove 211, thereby improving the smoothness of the protrusion 22 sliding into the bayonet 44, and improving the assembly efficiency of the cover body 1 and the connector body 4.
[0108] Please refer to Fig.11 In addition to using the limiting platform 12 to cooperate with the protruding portion 22, the protruding portion 22 itself can also realize the circumferential locking of the cover body 1 at the opening. Specifically, in other possible implementations of the present application, the bayonet 44 has two stopper surfaces 441b arranged opposite to each other in the circumferential direction of the connector body 4, and the protruding portion 22 has two abutting surfaces 221b arranged opposite to each other in the circumferential direction of the cover body 1. When the protruding portion 22 enters the bayonet 44 from the first card slot 45 and the cover body 1 is in a tightened state, the two abutting surfaces 221b of the protruding portion 22 abut against the adjacent stopper surfaces 441b, so as to limit the clockwise and counterclockwise rotation of the cover body 1, thereby locking the cover body 1 at the opening.
