In the related art, a cable module generally welds a core wire to a circuit board fixed in a housing. However, the space in the shell is limited, and the space utilization rate is not high, so that when the adopted core wires are thick wires or the core wires needing to be laid are arranged in a large number, extrusion interference is easy to occur between the core wires or between the core wires and other structural members, and the assembly quality of the cable module is further affected. Therefore, in order to increase the space utilization rate in the housing, the technical scheme of the present utility model is as follows, and is described with reference to fig. 1 to 5:

referring to fig. 1 to 3, the present utility model discloses a cable module, which includes: a housing 10, a circuit board 20 and a cable 30. Wherein the housing 10 is a mounting base of the cable module, the housing 10 may have a receiving cavity 110 therein, and at least a portion of the circuit board 20 may be fixed in the receiving cavity 110.

The cable 30 may include a plurality of core wires 310, at least a portion of the core wires 310 being received in the receiving cavity 110; wherein, at least one core wire 310 is electrically connected to an edge region of the circuit board 20, and at least one core wire 310 is electrically connected to a middle region of the circuit board 20. It is understood that the areas of the circuit board 20 other than the edge areas all belong to the middle area, such as the edge areas disposed around the middle area.

Wherein the core wire 310 for connecting the edge area of the circuit board 20 is at least partially overlapped with the circuit board 20 in the height direction X, such as the core wire 310 for connecting the edge area of the circuit board 20 is completely overlapped with the circuit board 20 in the height direction X, or the core wire 310 for connecting the edge area of the circuit board 20 is partially overlapped with the circuit board 20 in the height direction X. The core wire 310 for connecting the middle region of the circuit board 20 is not overlapped with the circuit board 20 in the height direction X.

It can be seen that, by transferring the connection position of a portion of the core wires 310 to the edge area of the circuit board 20, the circuit board 20 and the core wires 310 connected to the edge area of the circuit board 20 can be multiplexed in height, so that the occupation of the height space by the plurality of core wires 310 and the circuit board 20 can be reduced without increasing the space of the accommodating cavity 110, and further, the extrusion degree between the core wires 310 or between the core wires 310 and the circuit board 20 can be reduced, the extrusion interference can be prevented, the space utilization rate in the housing 10 and the assembly quality of the cable module can be improved, and the cable module is particularly suitable for the case that the core wires 310 with the required layout are thicker.

Alternatively, referring to fig. 3 to 5, the plurality of core wires 310 are divided into a first partial core wire 310a, a second partial core wire 310b, and a third partial core wire 310c which are sequentially disposed toward the height direction X of the housing 10.

Thus, the core wires 310 can be laid out as many as possible in the housing 10 while improving the space utilization in the housing 10, and the conduction capability between the cable 30 and the circuit board 20 can be improved.

Alternatively, the plurality of core wires 310 may be arranged side by side toward the width direction Y of the housing 10 to form a core wire row, the width direction Y intersecting the height direction X; the first partial core wire 310a, the second partial core wire 310b, and the third partial core wire 310c may each include at least one group of core wire rows. This can further increase the number of core wires 310 laid out in the housing 10, further improving the electrical conduction capability.

Alternatively, each of the first partial core wire 310a, the second partial core wire 310b, and the third partial core wire 310c may include a plurality of core wire rows, or may include only one core wire row, and the plurality of core wire rows in the present utility model include a first core wire row 311, a second core wire row 312, a third core wire row 313, and a fourth core wire row 314 in this order in the height direction X. The first partial core wire 310a includes a first group of core wire rows 311; the second partial core wire 310b includes a second group core wire row 312; the third partial core wire 310c includes a third group core wire row 313 and a fourth group core wire row 314. In this way, the third portion of the core wire 310c can further improve the layout rationality and the electrical conductivity of the core wire 310 due to the provision of a plurality of core wire rows.

Alternatively, the circuit board 20 has a first end face 21 and a second end face 22 disposed opposite to each other in the height direction X. The first end face 21 is provided with a first connection zone remote from the edge zone and located in the intermediate zone.

The second group core wire row 312 at least partially overlaps the circuit board 20 in the height direction X, and the second group core wire row 312 is connected to the second connection region through the terminal 301. At least a portion of the third group core wire row 313 and at least a portion of the fourth group core wire row 314 are each directed toward the second end face 22, and the third group core wire row 313 is connected to the third connection region through the terminal 301, and the fourth group core wire row 314 is connected to the fourth connection region through the terminal 301.

In this way, the arrangement of the plurality of connection areas of the first core wire row 311 attached to the first end surface 21 and the second end surface 22 can further improve the layout rationality of the core wires 310, and enable the core wires 310 and the circuit board 20 to better fill the accommodating cavity 110, so as to improve the space utilization rate in the accommodating cavity 110.
