Description

Technical Field

[0001] This utility model relates to the field of wire harness application technology, and in particular to a high-current energy storage battery wire harness and its riveting and positioning fixture. Background Technology

[0002] In the production process of high-current energy storage batteries, the connection quality of the wiring harness is crucial, and riveting is one of the key processes in wiring harness connection. High-current energy storage battery wiring harnesses are usually characterized by thick wire diameter and large conductor cross-sectional area. If the wiring harness is not accurately positioned or not firmly fixed during the riveting process, it is very easy to cause problems such as loosening and poor contact at the riveting point, which will affect the performance and safety of the battery.

[0003] Currently, high-current wire harnesses typically use sleeve-type connections at the joints, which can cause the sleeve to slip off, hindering stable use. Furthermore, most positioning fixtures used for wire harness riveting have simple structures and low positioning accuracy. For thicker wire harnesses like high-current energy storage battery harnesses, they are difficult to securely clamp, and displacement easily occurs during riveting, leading to unstable riveting quality, low production efficiency, and inability to meet the needs of mass production. Therefore, this utility model proposes a high-current energy storage battery harness and its riveting positioning fixture. Utility Model Content

[0012] With the above technical solution, the drive cylinder is activated, and its drive rod drives the slide plate on the end face to slide on the slide bar, so that the two positioning seats can reciprocate to correspond to the top pressing mold, thereby realizing the reciprocating uninterrupted pressing operation.

[0013] The present invention is further configured such that: the top of the positioning seat is provided with a positioning groove for the anti-interference connector, the inner sidewall of the positioning groove is symmetrically configured as inclined surface A, and the two side walls of the mold are provided with inclined surface B that matches inclined surface A.

[0016] The above technical solution facilitates the positioning and fixing of the adjusted plate using a clamp connected by a torsion spring.

[0017] The present invention is further configured such that: a tapered column with a fixed connecting head annular end is fixedly connected to the end face of the adjusting plate, and a locking block is provided on the end face of the locking plate, and the locking block is locked into a locking groove opened at the bottom of the adjusting plate.

[0018] The above technical solution facilitates the fitting of the annular end of the connector onto the tapered column and the use of the positioning groove for limiting and fixing. The cooperation between the locking block and the locking groove enables the adjustment plate to be adjusted and fixed.

[0019] The present invention is further configured such that: mounting holes are provided at the top of the mold near the corners, and arc-shaped grooves are symmetrically provided at the bottom of the mold near the center.

At the same time, the connection is crimped and fixed in an arc shape so that the harness body 1 can be firmly connected with bolts. The crimping joint between the harness body 1 and the connectors 11 is covered with a protective sleeve 12 to protect the connection.

[0033] like Figure 2 and Figure 3 As shown, a riveting and positioning fixture for a high-current energy storage battery harness is characterized by: a mounting plate 2 for mounting and fixing the entire positioning fixture; a drive mechanism 3 mounted on the top of the mounting plate 2 for reciprocating drive of the connector 11 and the harness body 1 to achieve riveting operation; the drive mechanism 3 includes a drive cylinder 31 mounted on the mounting plate 2; a slide plate 32 is bolted to the end face of the drive rod of the drive cylinder 31; the bottom of the slide plate 32 is slidably connected to the slide bar 21 bolted to the top of the mounting plate 2; two sets of symmetrically arranged fixing blocks 33 are fixedly connected to the top of the slide plate 32; and the two sets of fixing blocks 33 are respectively bolted to the connecting holes 41 opened near the corners on both sides of the two positioning seats 4; when the drive cylinder 31 is activated, its drive rod drives the slide plate 32 on the end face to slide on the slide bar 21, so that the two positioning seats 4 can reciprocate to correspond to the top pressing mold 5, thereby realizing a reciprocating and uninterrupted pressing operation.

[0034] like Figure 4 and Figure 5As shown, two positioning seats 4 are bolted to the drive mechanism 3 to position and fix the connector 11. The top of the positioning seat 4 is provided with a positioning groove 42 to prevent the connector 11 from being positioned. The inner sidewall of the positioning groove 42 is symmetrically set as inclined surface A43. The two side walls of the pressing mold 5 are provided with inclined surface B52 that matches the inclined surface A43, so that the pressing mold 5 can press down along the inclined surface A43 using the inclined surface B52 during pressing, thereby pressing and fixing the two sides of the connector 11 at the bottom. One end of the positioning seat 4 is slidably connected to an adjusting plate 44, and the end face of the adjusting plate 44 is fixedly connected to the fixing connector 11. The tapered column 441 at the annular end has a locking block 451 on its end face. The locking block 451 engages with the slot 442 at the bottom of the adjusting plate 44, so that the annular end of the connector 11 can be sleeved on the tapered column 441 and fixed in place with the positioning slot 42. The engagement of the locking block 451 and the slot 442 allows the adjusting plate 44 to be adjusted and fixed. The bottom of the adjusting plate 44 is engaged with the locking plate 45, and the locking plate 45 is rotatably connected to one end of the positioning seat 4 by a torsion spring, so that the adjusted adjusting plate 44 can be positioned and fixed by the locking plate 45 connected by the torsion spring.

[0035] like Figure 6 As shown, the pressing die 5, which works with the positioning seat 4 to perform the riveting operation, is installed on an external riveting device to fix the positioned connector 11 to the wire harness body 1. The top of the pressing die 5 is provided with mounting holes 51 near the corners, and the bottom of the pressing die 5 is provided with symmetrical arc-shaped pressing grooves 53 near the center. The mounting holes 51 are used to bolt to the external riveting device.

[0036] In use, the connector 11 is first placed on the positioning groove 42 and fixed by the conical column 441. Then, the drive cylinder 31 is started, and its drive rod drives the end plate 32 to slide on the slide bar 21, so that the two positioning seats 4 can reciprocate to correspond to the top pressing mold 5. Then, the external riveting equipment is started to drive the pressing mold 5 to press down. The arc-shaped pressing groove 53 is used to press the two sides of the connector 11 in an arc shape, so that it is stably wrapped and pressed into the end of the wire harness, so that it remains firm during use.
