[0002] With the continuous development of automotive electronic technology, the types and quantities of automotive electronic products are increasing, and the number of wiring harnesses used to connect various electronic products in the car body is also increasing. The same circuit often needs to connect three or more functional ends, which requires multiple wires to be short-circuited together during the wiring harness production process to form an interconnected circuit.

[0003] In the past, the methods for short-circuiting and paralleling wire harnesses generally include: stripping the wire harnesses, welding multiple wire harnesses separately and then wrapping them with tape for insulation; or transferring through the circuit board and welding each wire harness to the PCBA board. These methods have low production efficiency, insufficient welding reliability, and messy and unsightly wire harnesses.

[0004] However, some existing connectors with short-circuit function often have poor contact between terminals and shorting pieces during use. The reason is that the terminals are connected to wiring, and the wiring has a certain quality, which causes the wiring to naturally bend downward, pulling the terminals out of the connector, thereby causing relative movement between the terminals and the shorting piece.

[0047] Specifically, the minimum axial diameter of the terminal 210 is greater than the maximum axial diameter of the wiring 220. In this way, the terminal 210 and the wiring 220 are connected end to end, the terminal 210 is a large diameter section, and the wiring 220 is a small diameter section, and the connection between the two forms an abutment surface 230. The housing 110 includes a peripheral side wall and a partition wall. The peripheral side wall is enclosed in a cylindrical shape. The partition wall is fixed in the peripheral side wall to separate the space in the peripheral side wall into at least two through holes 111; the short-circuit 120 is a metal part with conductive properties, installed in the housing 110, and located at one end of the through hole 111; the terminal 210 is at least partially inserted at the other end of the through hole 111, and the terminal 210 and the short-circuit 120 are inserted in the through hole 111. The terminals 210 located in different through holes 111 can be connected through the short-circuit 120 to form a short circuit. Furthermore, in order to limit the terminal 210 from withdrawing from the through hole 111 or moving along the axial direction of the through hole 111 toward the side opposite to the short-circuit 120, resulting in poor contact between the terminal 210 and the short-circuit 120, in this embodiment, a protective shell 130 is also provided. The protective shell 130 is sleeved on the outside of the outer shell 110, and the anti-retraction portion 131 of the protective shell 130 is located on the side of the terminal 210 opposite to the short-circuit 120 to prevent the terminal 210 from moving along the first direction X, that is, the axial direction of the through hole 111, so that the terminal 210 remains relatively fixed with the outer shell 110 and remains connected with the short-circuit 120.

[0048] Optionally, the housing 110 has two first side walls 112 opposite to each other in the second direction Y, and first protrusions 122 are provided on opposite sides of the short-circuit 120. At least one of the short-circuit 120 and the first protrusion 122 can be elastically deformed in the second direction Y, and the first protrusion 122 can be inserted into the first clamping hole 113. The first direction X is perpendicular to the second direction Y. In this way, the first protrusion 122 is plugged into the first clamping hole 113 along the second direction Y, and the plug-in relationship between the two can limit the movement of the short-circuit 120 and the housing 110 perpendicular to the first direction X.

[0049] Optionally, the short-circuit 120 is U-shaped. Shorting piece 120 It also includes a connecting portion 123 and a fixing portion 124. Two fixing portions 124 are provided in the second direction Y. The two fixing portions 124 are connected by the connecting portion 123.

In this way, the short-circuit 120 and the housing 110 can be plugged in along the first direction X. The contacts 121 are the first parts to enter the corresponding through holes 111 respectively. The guide surface of the first convex head 122 makes it easier to insert the fixing portion 124 into the housing 110. When the first convex head 122 provided on the fixing portion 124 is aligned with the first clamping hole 113, the first convex head 122 is inserted into the first clamping hole 113 along the second direction Y.

[0050] Optionally, the housing 110 is provided with a second limiting groove 117 along the second direction Y and / or the third direction Z, the second limiting groove 117 is formed on the axial end face of the through hole 111, and the connecting portion 123 of the short-circuit 120 is provided with a second limiting protrusion 125, and the second limiting protrusion 125 is inserted into the second limiting groove 117 along the first direction X; the first direction X, the second direction Y and the third direction Z are perpendicular to each other. In this way, the connecting portion 123 of the short-circuit 120 is the tail end, and during the plug-in process, when the second limiting protrusion 125 is inserted into the second limiting groove 117 along the first direction X and abuts against the bottom wall of the second limiting groove 117, it is considered that the short-circuit 120 and the housing 110 are installed in place, so as to prevent the contact 121 of the short-circuit 120 from being inserted too deeply to one side of the terminal 210, thereby affecting the plug-in of the terminal 210 and the through hole 111.

[0051] Optionally, the first side wall 112 is further provided with a second snap-fitting hole 114, and the second snap-fitting hole 114 is used to snap-fit ​​with the second protrusion 211 of the terminal 210, forming a limit in the first direction X. Specifically, the second protrusion 211 includes a first state of being fitted with the terminal body and a second state of being separated from the terminal body, and the second protrusion 211 can be elastically deformed and tend to be away from the terminal body. When the terminal 210 is inserted into the through hole 111 along the first direction X, the second protrusion 211 is squeezed by the first side wall 112 of the housing 110 and maintains the first state. When the second protrusion 211 is aligned with the second snap-fitting hole 114, the second protrusion 211 recovers the deformation and switches to the second state, is inserted into the second snap-fitting hole 114, and can abut against the side wall of the second snap-fitting hole 114 along the first direction X to limit the terminal 210 from withdrawing from the housing 110.

The protective shell 130 is plugged with the outer shell 110 along the third direction Z to avoid the wiring harness 200, and the protective shell 130 and the outer shell 110 are limited by the plugging of the third protrusion 115 and the third clamping hole 134.

[0053] Optionally, the second side wall 133 is provided with a first limiting groove 135 along the third direction Z, and the housing 110 is correspondingly provided with a first limiting protrusion 116, and the first limiting protrusion 116 is slidably plugged into the first limiting groove 135.

The back plate 136 can block the opening of the through hole 111 on the side where the short-circuit 120 is located. In this way, the short-circuit 120 can be directly inserted into the through hole 111 from one end of the through hole 111, and then blocked by the back plate 136, so that the short-circuit 120 cannot be withdrawn from the through hole 111 along the first direction X.
