The wire harness connector clamping structure 6 is mainly used for fixing a common low-voltage wire harness connector; the FAKRA connector clamping structure 7 is specially used for fixing the FAKRA connector.
The FAKRA connector is explained as follows: the FAKRA connector is "FAChKReis Automobile" in Germany. The acronym developed, the specifications of which were compiled by the branch commission within the german automotive manufacturing committee, was originally a BMW requirement for car radio antenna connections, and FAKRA is now a universal standard radio frequency connector for the automotive industry and is widely used in the industry. The application range of the wire harness fixing device is further expanded by arranging the clamping structure suitable for different connectors.
Wherein, the number of the installation rooms 8 of the installed FAKRA connector clamping structure 7 is less than that of the installation rooms 8 of the wiring harness connector clamping structure 6.
Fig. 1 to 3, fig. 6 show an embodiment of a wire harness connector clamping structure 6, the wire harness connector clamping structure 6 includes two first clamping main bodies 64 disposed on a partition board of an installation room 8, a first anti-withdrawal rib 62 is disposed between the two first clamping main bodies 64, first clamping ribs 61 extending in opposite directions are disposed at ends of the two first clamping main bodies 64, and a first guide clamping groove 65 is formed between the first clamping ribs 61 and the partition board of the installation room 8. Six harness connector snap structures 6 are provided in this embodiment. Wherein the end surface of the first clamping rib 61 constitutes a guide surface.
The following description is made of the respective portions of the wire harness connector clamping structure 6: referring to fig. 6, (1) guide surface: the back buckle fixing structure of the low-voltage wire harness connector of the automobile is a junction surface, namely a reference surface, when the back buckle fixing structure of the low-voltage wire harness connector of the automobile is clamped with the connector fixing structure of the device; (2) clamping ribs: the rib is a key structure of the device connector fixing structure, and the clamping rib is a main rib which can clamp the device connector fixing structure and the wire harness connector together; (3) a guide clamping groove: when the connector fixing structure of the device is clamped with the wire harness connector, the clamping groove is used for guiding the wire harness connector in the sliding direction; (4) chamfering clamping ribs: in order to facilitate the smooth entering of the wire harness connector into the connector clamping structure of the device when the wire harness connector is clamped, a chamfer is arranged on the end face of the clamping rib towards the leading-in direction; (5) preventing rib withdrawal: a first anti-back-off groove 63 is formed between the two first clamping main bodies 64, and the first anti-back-off rib 62 is arranged in the first anti-back-off groove 63, so that the wiring harness connector can be prevented from being withdrawn from the wiring harness connector clamping structure 6 after being clamped, and the fixing stability of the wiring harness connector is improved; (6) clamping a main body: and the mounting room 8 and the base body are integrally molded, so that the wire harness connector is firmly and stably fixed. This device pencil connector joint structure 6 can advance and retreat length and adjust according to the car low pressure pencil connector back of the body knot type of fixing, and it is fixed to conveniently be suitable for multiple pencil connector.
Fig. 7 shows as an implementation of FAKRA connector clamping structure 7, including two second clamping main bodies 74 that set up on the baffle of installation room 8, be equipped with the second that extends to the baffle of installation room 8 between two first clamping main bodies 64 and prevent moving back groove 72, the second is prevented moving back and is equipped with the second in the groove 72 and prevents moving back muscle 71, the both sides face that deviates from on two second clamping main bodies 74 is equipped with reverse second joint muscle 73 that extends, constitutes second direction draw-in groove 75 between second joint muscle 73 and the baffle of installation room 8.
The pencil fixing device that this embodiment provided except that car low pressure wire harness connector fixed knot constructs, FAKRA connector joint structure 7 in addition, because FAKRA connector joint structure 7 is different with ordinary wire harness connector fixed knot structure, secondly FAKRA connector does not have relevant back of the body at present and detains and supply it fixed, most motorcycle types are for not having fixedly, FAKRA connector joint structure 7 that this embodiment provided detains fixed knot structure design and supplies it fixed according to FAKRA connector back of the body. Similar to the wire harness connector clamping structure 6, the FAKRA connector fixing structure also has structures such as a guide surface, a clamping rib, a guide clamping groove, a clamping rib chamfer, an anti-retreating rib, an anti-retreating groove and a clamping main body. Each structural function is the same, the main difference lies in the structure of preventing moving back the groove, the position that prevents moving back the muscle setting and the position that the joint muscle set up with ordinary low pressure wire harness connector has some differences, FAKRA connector joint structure 7 prevents moving back the muscle at the rear of joint muscle, this paper, because two kinds of joint structures have certain differences, consequently first and second have been distinguished on the name, but when the function description, in order to simplify and be convenient for the description, no longer distinguish first and second, the detailed contrast is seen in figure 6 and figure 7. FAKRA connector is because of its structural particularity, prevent moving back the muscle and prevent moving back the inslot and keep away from the setting of joint muscle, go into the back at FAKRA connector card, inwards promote FAKRA connector, when FAKRA connector is pushed away the position of joint regulation, prevent moving back the inslot and prevent moving back muscle and FAKRA connector joint, and when butt joint with the connector in the butt joint, the tight stiff end FAKRA connector in top of fastening, make FAKRA connector can't withdraw from.
As shown in fig. 1 to 5, the wire harness fixing device of the present embodiment needs to be integrally detachably connected and fixed with the peripheral component, and therefore, the substrate 1 is further provided with a fixing structure for integrally fixing with the peripheral component. Two-point positioning is adopted, so that the whole body can be reliably fixed.
As for the manner of fixing the structure, the following is exemplified: the bolt fixing structure 3 and the clamping fixing structure 10 are combined and fixed on the peripheral part in two modes, so that the tolerance of the fixing hole of the peripheral part can be absorbed, and the tolerance of the device can be absorbed. Further, in order to prevent the bolt from being directly fastened to the base body and deforming the entire wire harness fixing device, an elastic washer 2 is provided at the time of bolt connection, as shown in fig. 1. The bolt can be fixed by a bolt with a gasket in M6/M8 according to the condition of the peripheral parts; joint fixed knot constructs 10 and borrows ordinary 7X 12 arrow point type ribbon head, does not have ribbon spring bolt and area body, and 7mm X12 mm arrow point type ribbon head is direct to mould plastics as an organic whole structure with pencil fixing device is whole, increases pencil fixing device fixed stability and fastness.
The above is the optimum mode of the wire harness fixing device. In another embodiment, all the clamping fixing structures 10 can be provided with oblong holes of 7mm × 12 mm; two bolt fixing structures 3 can also be adopted, and the fixing structures can also be replaced by other fixing structures.
