Mode of execution
In order to make the utility model to solve the technical problems, the technical scheme and the advantages more clearly, the lower portion of the Figure and a detailed description of the specific embodiment.
Figure 1 is the structure diagram of the driving cab of the harness centralized grounding assembly of the present utility model; Figure 2 is the structure diagram of the ground terminal and the female end of the connector in a state of separation of the present utility model; Figure 3 is the front view of the ground terminal of the present utility model; Figure 4 is the side view of the grounding terminal of the present utility model; Figure 5 is the enlarged view of the region of the ring in Figure 4; Figure 6 is the structure diagram of the ground terminal and the female connector in the state of combination of the present utility model.
As shown in Figure 1 and Figure 2, embodiment of the utility model to provide a driving cab harness centralized grounding assembly, including: the male end connector 1, the female end terminal, the female end connector 2 and ground terminal 3, the terminal arrangement in the [...][...] connector 1 in, the [...] connector 2 and the lower end of the upper end of the opening, the connector [...] 1 from the [...] connector 2 is inserted into the upper end of, the ground terminal 3 from the [...] connector 2 is inserted into the lower end of the, to the terminal butting [...] with, the grounding terminal 3 and the [...] connector 2 are fixed through a clamping structure.
As shown in Figure 3 and Figure 4, the ground terminal 3 including the insertion part 302 and the grounding part 301, the inserting part 302 for and female terminal insertion, the grounding part 301 for connected to the car body on the sheet. The states peg grafting department 302 is formed to the shape of the side of the U-shaped (as shown in Figure 4). In particular, the insertion part 302 includes a spacing configuration of the two inserting end 303 and connecting two of the end connecting end 307, two inserting end 303 and a connecting end 307 with the U-shaped shape is formed. Each plugging end of the 303 since the connecting end 307 extends upwards to form a, in particular perpendicular to the formed extending over, the [...] 303 includes a connecting end 307 connected with the basal body and since the base body is extended upwards to form a plurality of linearity body 304, a plurality of linearity body 304 is spaced between the configuration. In one example, all of the linearity body 304 of the same height, and is used with the female terminal butt, in addition, can be in the strip-shaped body is formed with the peripheral surface of the chamfer.
The ground part 301 since the splicing end 303 is bent downwards to form, and in the end part is formed with a through hole 306, the grounding part 301 through the through hole 306, by the bolt fixed on the vehicle body sheet metal. Specifically, the grounding part 301 from a ground terminal 303 is bent downwards to form, as shown in Figure 4, can be first extends downward to a certain position, then bent to extend in the horizontal direction, the horizontal direction after the extend a predetermined distance, extend a predetermined distance downward, thus forms the bending the grounding part of the 301, in actual production, the grounding part 301 can be formed connected with the inserting end of the 303 of the material is bent downwards to form.
In more detail, the two plugging end of the 303 in the inserting end of the inserting end called a 1st, another known as the 2nd inserted end, wherein said 1st is connected with the end of the plug is formed with a predetermined interval a plurality of strip-shaped configuration, for example, formed at predetermined intervals 8 a strip body, the 2nd is inserted and formed at the interval of the two array configuration, each of the array of the sets includes a predetermined interval a plurality of strip-shaped configuration, for example, each array group can include formed at predetermined intervals 3 a strip body, this 3 a strip body with the spacing between the plugging end of the 1st on the same to the space between the strip-shaped body, the grounding part 301 since the two array group that extends between and is bent downwards to form. In this way, in the use of the plate-shaped material to form a grounding terminal of the, in the material forming the U shape at the rear, in the plugging end of the 1st cutting at predetermined intervals to form a plurality of strip body is, in the 2nd inserted end respectively at predetermined intervals in the left and right ends of the two array formed by cutting, will lie between the two array group in accordance with a predetermined pattern of material downward bent to form a grounding part 301. In other words, the grounding part 301 and the insertion part 302 can be integrally formed of one piece of material, not through the separated after the formation of the connected together, for example by welding or bolt-connected together, therefore can greatly reduce the ground terminal of the resistance, good conductivity.
Further, as shown in Figure 5 and Figure 6, [...] structure comprises a along the length of the side of the substrate form in the direction of the strip-shaped groove 305 and is formed in the female connector 2 with the lower end of the inner side of the groove 305 is matched with the projecting part 202, in this way, when the ground terminal 3 from the parent end connector 2 is inserted into the lower end of the, ground terminal 3 will be card in the groove on the lug 202, so that the grounding terminal 3 is installed in the female end of the connector is clamped 2 on. In the utility model in another embodiment, the female connector 2 is formed at the lower end of the states peg grafting department corresponding to the shape of the cross section of the concave hole 201, said concave hole 201 formed at both sides of the said lug of the 202, such can be conveniently ground terminal 3 of the insertion and withdrawal. It must be noted that, the clamping structure of the utility model can also be other forms of structure, so long as they can realize the female connector 2 and ground terminals 3 can be connected between the.
In the use of the utility model when the grounding component in, all the wire which is needed, press-fit in the female end terminal of the male connector is inserted into the female connector after, and is inserted into the female connector in the butt of the grounding terminal, then the grounding terminal using the bolt of the grounding part and the vehicle body sheet metal are screwed together, all need to ground the wire harness through the ground terminal 3 is connected with the vehicle body sheet metal, to realize the grounding function, thereby realizing the end terminal and the ground terminal - - the car body sheet metal - the battery negative loop, the completion of the ground function.
It must be noted that, the utility model of the male connector and the female terminal can adopt a prior connector structure, the male connector can be formed in a preformed hole, in order to promote the variable vehicle harness design and retrofit convenience.
The foregoing the preferred embodiment of the utility model, it should be noted that, for the technical field for the ordinary technical personnel, in the utility model does not break away from the premise of the principle, can also be made a number of improvements and polished, these improvements and polished should also be considered the utility model the scope of protection.
