Detailed Description
Referring to fig. 1 to 4, a specific structure of a preferred embodiment of the utility model is shown, which is a new energy automobile power battery pack communication harness.
The new energy automobile power battery pack communication wire harness comprises a main wire harness 10, a plurality of connectors 20 and a plurality of heat-shrinkable sleeves 30. In the embodiment of the present application, the main harness 10 is provided with a plurality of branch harnesses 11, the connectors 20 are connected one by one corresponding to both ends of the main harness 10 and ends of the branch harnesses 11, and the heat shrink sleeve 30 is wrapped around each connector 20 and the connection of the harnesses. Specifically speaking, this heat-shrinkable tube 30's front end is provided with the first parcel mouth 31 that is used for wrapping up the connector 20 afterbody, the rear end is provided with the second parcel mouth 32 that is used for wrapping up the pencil tip, this first parcel mouth 31 and second parcel mouth 32 intercommunication, this first parcel mouth 31's medial surface bottom is provided with a plurality of stereoplasm plastic parts 33 that are "worker" style of calligraphy, the bottom embedding of this stereoplasm plastic part 33 is first parcel mouthful 31's medial surface bottom, per two stereoplasm plastic parts 33 constitute a logical groove 330 that is used for holding the heart yearn, this heat-shrinkable tube 30 wraps up connector 20 and pencil, the medial surface top of stereoplasm plastic part 30's the embedding first parcel mouth 31. Because the number of the core wires of the battery pack communication wire harness is large, if the connecting part of the connector and the wire harness is only wrapped by the sheath, the core wires are difficult to be completely compressed, the possibility of loosening still exists in the later period, once the loosening occurs, external moisture can permeate into the core wires to further corrode the core wires, and the normal use of the communication wire harness is seriously influenced; therefore, the plurality of core wires are regularly arranged through the hard plastic part and then are subjected to thermal shrinkage wrapping; when heating heat-shrinkable tubing, heat-shrinkable tubing's shrink can drive a plurality of stereoplasm plastic parts and carry out the extrusion and press from both sides tight corresponding heart yearn, and heat-shrinkable tubing's the plastic of upper and lower extreme also can imbed the corresponding tight heart yearn of clamp in leading to the groove, and heat-shrinkable tubing is more firm to the parcel of heart yearn like this, can reduce not hard up problem effectively to promote its prevention of seepage and permeate the performance, guarantee to use more reliably, also can prolong communication wiring harness's life.
The rigid plastic part 33 is composed of a central part 331, a plurality of left side parts 332 and a plurality of right side parts 333, the central part 331 is arranged in the middle of the first wrapping opening 31, the plurality of left side parts 332 are sequentially arranged on the left side of the central part 331, and the plurality of right side parts 333 are sequentially arranged on the right side of the central part 31; moreover, the left side pieces 332 are all arranged obliquely from inside to outside to the left with the central piece 331 as a reference; the right members 333 are each inclined from the inside to the outside to the right with respect to the central member 331 at an angle of 5 ° to 10 °. So set up, can let the heart yearn of arranging arrange with umbrella-type shape, after heat-shrinkable bush pyrocondensation, the heart yearn that is located the outside is difficult for receiving heat-shrinkable bush's pulling force and produces and drag, when preventing the pyrocondensation, the heart yearn breaks away from with being connected of connector, improves the product yield after the pencil is made.
As mentioned above, in order to allow heat shrink 30 to be adapted for use with different configurations of connector 20; the front surface of the rigid plastic part 33 is 30mm away from the front surface of the first wrapping opening 31, so that the first wrapping opening 31 of the heat-shrinkable sleeve 30 can be firmly wrapped at the rear end of the corresponding connector 20. The inner side surface of the second wrapping opening 32 of the heat-shrinkable sleeve 30 is provided with a convex strip for embedding the wire harness outer cover, and the convex strip 34 is arranged in a ring shape along the circumference of the second wrapping opening 32 and is a plurality of strips arranged at intervals inside and outside; the grooves with corresponding quantity are arranged on the outer cover of the wire harness, so that the convex strips can be embedded into the grooves, and the connection strength of the heat-shrinkable sleeve is increased.
The branched wire harness 11 comprises a first branch 111, a second branch 112, a third branch 113, a fourth branch 114 and a fifth branch 115; the connector 20 comprises a main connector 21, a first signal connector 22, two second signal connectors 23, a third signal connector 24 and two fourth signal connectors 25; the main connector is connected to one end of the main wire harness, the first connector is connected to the end of the first branch, the two second signal connectors are connected with the third branch correspondingly, the third signal connector is connected to the fourth branch, the fourth signal connector is connected to the fifth branch, and the other fourth signal connector is connected to the other end of the main wire harness.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
