Description

Wire set

Technical Field

The present utility model relates to a wire set, and more particularly, to a wire set for connecting a plurality of wires.

Background

Techniques for combining parallel circuits by connecting a plurality of wires to a single conductive terminal have been widely used. The plurality of wires connected to the same conductive terminal and receiving the same signal may be connected to different devices, such as a control device and an interpretation computer, respectively.

However, when assembling a plurality of wires to a single conductive terminal, it is difficult to implement an automated production process for assembling the wires to the conductive terminal with mechanical automation due to problems such as alignment between ends of the plurality of wires. Therefore, the current manufacturing method is mainly to manually assemble a plurality of wires to a single conductive terminal. However, in the production method of manual assembly, besides being time-consuming and labor-consuming, the quality consistency is difficult to control.

In addition, the assembled conductive terminals may be used in vehicles or other easily impacted machinery. If the quality of the connection of the conductive terminal and the wire is unstable, the wire may be easily loosened by impact. Therefore, there is a need for further improving the connection between the conductive terminals and the wires.

First embodiment

Referring to fig. 1 and 2, fig. 1 and 2 are an exploded view and a perspective view, respectively, of a wire group according to a first embodiment of the present utility model when wires are arranged in a horizontal direction. In the present embodiment, the wire set 1 includes a plurality of wires 10, a plurality of transit terminals 100 and conductive terminals 200, wherein the wires 10 are arranged with each other and extend along the first direction D1, respectively. Each wire 10 has a wire outlet end 10A. For convenience of description, the arrangement direction of the plurality of wires 10 is referred to as a second direction D2, and in the embodiment shown in fig. 1 and 2, the second direction D2 refers to a vertical direction, and is preferably perpendicular to the first direction D1. For convenience of explanation, in the present embodiment, two wires 10 are taken as an example. However, the number of the wires 10 is not limited thereto, and the wire set 1 may include more than three wires 10 in different embodiments. Wherein, the plurality of switching terminals 100 respectively correspond to the plurality of wires 10.

As shown in fig. 1 and 2, each of the transit terminals 100 has opposite pin ends 110 and terminals 120, and each of the terminals 120 is connected to the outgoing end 10A of the corresponding wire 10. Specifically, the wire outlet 10A may be, for example, a bare wire with an insulation layer removed, and the terminal 120 may be a slot formed by punching and bending a metal plate from the body of the adapter terminal 100. The wire outlet end 10A is connected by a wire bonding process after extending into the terminal 120.

On the other hand, the conductive terminal 200 includes a socket structure 210 and a terminal 220. The socket structure 210 has at least one socket 211 into which the pin end 110 is inserted, and the terminal 220 is opposite to the socket structure 210 in the first direction D1, so that the conductive terminal 200 is electrically connected to the external connector 300 (shown in fig. 3). Latch ends 110 are aligned and inserted into slots 211. Specifically, each of the pin ends 110 may have a pin plane 110A, and when the pin ends 110 are inserted into the socket structure 210, the pin planes 110A of adjacent pin ends 110 are disposed parallel to each other, such that adjacent pin ends 110 are aligned side-by-side. Thereby facilitating control of the relative position between adjacent wires 10 and facilitating fully automated insertion. However, the shape of the pin end 110 is not limited thereto, and other methods may be used to align the pin end 110 and insert it into the slot 211.

In the embodiment shown in fig. 1 and 2, the arrangement direction (the second direction D2) of the wires 10 may be, for example, a vertical direction (i.e., a plurality of wires 10 are stacked upwards) as shown in the drawings. However, this is merely illustrative, and the arrangement direction of the wires 10 may be a horizontal direction, and the corresponding direction may be changed due to the direction of the moving wire set 1 during the use, which is not limited to this.

Referring to fig. 3, the assembled lead set 1 may be inserted into the external connector 300 through the terminal 220 of the conductive terminal 200, as shown in fig. 3. The external connector 300 may include, for example, a first housing 310 and a second housing 320 side by side along a first direction D1, wherein the first housing 310 is closer to the wire set 1 than the second housing 320, and the first housing 310 may have a plurality of connector slots 311 into which the terminals 220 are inserted. However, the structure of the external connector 300 shown here is illustrative, and the configuration thereof is not limited thereto.

Fig. 4 is a schematic perspective view showing a socket structure 210 in a conductive terminal 200 according to a first embodiment of the utility model. As shown in fig. 4, at least one isolation structure 213 extending along a third direction D3 different from the first direction D1 and the second direction D2 (e.g., may be perpendicular to both the first direction D1 and the second direction D2) is provided in the slot 211 of the slot structure 210, and opposite sides of the isolation structure 213 along the second direction D2 respectively form different accommodating areas in the slot 211 for accommodating the respective pin ends 110. Therefore, the phenomenon of poor transmission of electronic signals caused by sliding of the adjacent plug pin ends 110 in the slot structure 210 can be avoided. In addition, the isolation structure 213 also provides a guiding and diverting function when the pin end 110 extends into the slot 211, so as to reduce the protrusion of the pin end 110 into the accommodating area accommodating other pin ends 110, and the different wires 10 can be used independently without interfering with each other.

Referring to fig. 5, 6 and 7, fig. 5 is a schematic perspective view showing the pin end 110 of the adapting terminal 100 according to the first embodiment of the present utility model, and fig. 6 and 7 are a top view and a side view respectively showing the insertion of the pin end 110 into the slot structure 210 in the wire set 1 according to the first embodiment of the present utility model. As shown in fig. 5, the plug end 110 has an engaging portion 110B protruding from one end surface of the plug end 110 toward the third direction D3, and as shown in fig. 6 and 7, the engaging portion 110B engages with a corresponding positioning portion 212 in the slot 211.

In the present embodiment, the engaging portion 110B has a first inclined surface 110C and a second inclined surface 110D at a proximal side and a distal side along the first direction D1, respectively, with respect to the main body of the lead 10, and the first inclined surface 110C and the second inclined surface 110D have different inclination degrees. When the engaging portion 110B has inclined surfaces with different degrees of inclination at the proximal end side, the force required for insertion and extraction is different, so that the latch end 110 is not easily separated from the positioning portion 212 by an external force. Specifically, in the present embodiment, when the end surface of the plug end 10 is the reference surface, the first inclined surface 110C is preferably inclined to a greater extent than the second inclined surface 110D, so as to ensure that the force required for pulling out is greater than the force required for inserting the plug end 110, and further prevent the plug end from falling off under external force.

Referring to fig. 4 again, in the present embodiment, the socket structure 210 has a first sidewall 210A and a second sidewall 210B opposite to each other in the second direction D2. In the present embodiment, the slot structure 210 into which two pin ends 110 are inserted is taken as an example. The isolation structure 213 includes one or more first isolation structures 213A extending from the first sidewall 210A and extending along the third direction D3 (i.e. the direction parallel to the first sidewall 210A) towards the inside of the socket structure 210 after being folded back. The isolation structure 213 further includes one or more second isolation structures 213B extending from the second sidewall 210B and folded back to extend along the third direction D3 toward the inside of the socket structure 210. In this embodiment, the first isolation structures 213A may face a corresponding one of the second isolation structures 213B in the socket structure 210. Specifically, the first sidewall 210A and the second sidewall 210B may be formed by bending a same metal plate, and a cantilever connected to the first sidewall 210A and/or the second sidewall 210B may be cut out of the metal plate, and then bent to form the first isolation structure 213A and/or the second isolation structure 213B.

In the present embodiment, opposite sides of the first isolation structure 213A and the second isolation structure 213B along the second direction D2 respectively form different accommodating areas in the slot 211 for respectively inserting different pin ends 110, and the adjacent pin ends 110 are respectively positioned on opposite sides of the isolation structure 213 (the first isolation structure 213A and the second isolation structure 213B). By providing the first isolation structure 213A and the second isolation structure 213B extending in opposite directions between the slots 211, the adjacent pin ends 110 can be prevented from sliding in the slot structure 210 to deviate, thereby preventing poor transmission of electronic signals.

On the other hand, in the present embodiment, each slot 211 preferably has a positioning portion 212. For example, the first isolation structure 213A has a first positioning portion 212A on one side (e.g., upper side) along the second direction D2, and the second isolation structure 213B has a second positioning portion 212B on the other side (e.g., lower side) along the second direction D2. Thus, the first positioning portion 212A and the second positioning portion 212B are respectively located on different sides of the socket structure 210 along the third direction D3. In other words, the positioning portions 212 in two adjacent receiving areas separated by the isolation structure 213 are respectively located on different sides of the slot structure 210 in the third direction D3. In this embodiment, the positioning portion 212 is a notch or recess formed by cutting a metal plate, so as to accommodate and interfere with the positioning portion 212. In addition, as described above, in this embodiment, the metal plate is cut out to form the cantilever and bent to form the isolation structure 213, and the notch left after bending can be formed as the positioning portion 212.

In the present embodiment, the engaging portions 110B of two adjacent side-by-side latch ends 110 respectively protrude in opposite directions in the third direction D3, such that the engaging portion 110B of each latch end 110 can be respectively matched with the corresponding first positioning portion 212A or the second positioning portion 212B.

In addition, the slot structure 210 of the present embodiment may have a plurality of first isolation structures 213A and a plurality of second isolation structures 213B disposed parallel to each other along the first direction D1, and the pin end 110 may also have a plurality of engaging portions 110B according to the number of the first isolation structures 213A or the second isolation structures 213B. Furthermore, the number of the plug ends 110 into which the plug structure 210 of the present utility model can be inserted is not limited to two, and the plug structure 210 for more than three plug ends 110 can be changed. In addition, when the first isolation structure 213A or the second isolation structure 213B is plural, the stripe structures connecting the first sidewall 210A and the second sidewall 210B are spaced apart from each other, so as to increase the structural stability of the body of the socket structure 210.

Second embodiment

Referring to fig. 8 and 9, fig. 8 and 9 are an exploded view and a perspective view, respectively, of the wires 10 of the wire set 1 according to the second embodiment of the present utility model when the wires are arranged in a horizontal direction. Also in the first embodiment, for convenience of explanation, the extending direction of the wires 10 is the first direction D1, and the arrangement direction is the second direction D2. In the embodiment shown in fig. 8 and 9, the second direction D2 is a horizontal direction, but this is only for illustration, the arrangement direction of the wires 10 may be a vertical direction, and the corresponding direction may be changed due to the direction of moving the wire set 1 during use, which is not limited by the present utility model.

Referring to fig. 10, fig. 10 is a schematic perspective view of the conductive terminals 200 in the conductive wire set 1 electrically connected to the external connector 300 according to the second embodiment of the utility model. Also, as in the external connector 300 shown in fig. 3, the external connector may have a first housing 310 and a second housing 320, and the first housing 310 has a plurality of connector slots 311 into which the terminals 220 are inserted. In the case where the structure and the size of the terminals 220 are the same, the lead sets 1 of different embodiments (e.g., the first embodiment and the second embodiment) may be inserted into different connector slots 311 in the same external connector 300 at the same time. The main difference between the second embodiment and the first embodiment is the design of the transit terminal 100 and the socket structure 210, and these differences are described in detail below.

Referring to fig. 11, fig. 11 is a schematic perspective view of a slot structure 210 in a conductive terminal 1 according to a second embodiment of the utility model. An example in which two wires 10 are arranged in the horizontal direction will be described below. As shown in fig. 11, the socket structure 210 has a plurality of tubular/semi-tubular structures 214 arranged side by side along the second direction D2 on at least one side in the third direction D3 (for example, a direction perpendicular to both the first direction D1 and the second direction D2), such that a plurality of accommodating areas are formed corresponding to the plurality of tubular/semi-tubular structures 214 in the socket 211 surrounded by the socket structure 210. Each of the accommodating areas is configured for inserting a corresponding one of the plurality of pin ends 110, and the side cross-sectional shape of the tubular/semi-tubular structure 214 is not limited to the shape shown in fig. 11, and the side cross-section of the tubular/semi-tubular structure 214 may have any polygonal shape such as a rectangle, a triangle, a square, etc. In addition, in the second embodiment, the opposite sides of the slot structure 210 along the second direction D2 may also have a tubular/semi-tubular structure, but the utility model is not limited thereto. Specifically, the slot structure 210 may be made by bending a sheet metal piece, and two ends of the sheet metal piece may be bent more than 180 degrees toward the same side, so as to form two side-by-side approximately tubular accommodating spaces, thereby forming the slot 211.

Referring to fig. 12 and 13, fig. 12 and 13 are schematic perspective views of the switch terminal 110 and a side view of the switch terminal inserted into the slot structure 210 of the lead set 1 according to the second embodiment of the utility model. As shown in fig. 12, each of the adaptor terminals 100 of the present embodiment has an engaging portion 110B surrounding the adaptor terminal 100 near a portion at the plug end 110, and the plug end 110 has a tapered structure toward the first direction D1. As shown in fig. 13, the positioning portion 212 of the present embodiment is located on the same side as the tubular/semi-tubular structure 214 and between the socket structure 210 and the terminal 220, for example, the positioning portion 212 may be a hollow to position a portion of all the adaptor terminals 100 near the plug end 110 therein.

The engaging portion 110B of the present embodiment surrounds a portion of the adapting terminal 100 near the pin end 110 and at least partially faces a third direction D3 different from the first direction D1 and the second direction D2, and each adapting terminal 100 can be positioned at the positioning portion 212, so that the adapting terminal is not easy to be pulled out and fall off when being subjected to an external force.

In this embodiment, more than three tubular/semi-tubular structures 214 may be disposed on one side of the socket structure 210 according to actual needs, and the socket structure 210 into which more than three pin ends 110 are inserted may be changed.

In summary, the lead set 1 according to the present utility model can implement an automatic installation mechanism through the adaptor terminal 100 correspondingly connected to the outlet end 10A of the lead 10 and at least one slot 211 corresponding to each adaptor terminal 100 in the slot structure 210 of the conductive terminal 200. Furthermore, the engaging portion 110B and the positioning portion 212 on the adapter terminal 100 can further prevent the adapter terminal 100 connected to the lead 10 from being accidentally separated from the slot 211 when an external force is applied.

What has been described above is merely a few preferred embodiments of the present utility model. It should be noted that the present utility model can be modified and adapted in various ways without departing from the spirit and principle of the present utility model. It will be apparent to those skilled in the art that the present utility model is defined by the scope of the appended claims, and that various substitutions, combinations, modifications, and changes may be made without departing from the scope of the utility model defined by the scope of the appended claims.
