Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, and in particular to a compact terminal strip structure. Background Technology

[0002] In the field of electronic connectors, terminal strips are widely used in the automated production processes of electronic products. Terminal strips typically consist of multiple spaced-apart terminal units and are transported via carrier tape to facilitate subsequent processes such as stamping, welding, and assembly.

[0003] In existing traditional terminal tape structures, the spacing between adjacent terminals is relatively large. This is mainly due to the inherent structural limitations of the terminals, which restrict the space between adjacent terminals and prevent further reduction in spacing. This large terminal spacing leads to an increase in tape width, affecting the overall compactness of the connector, resulting in material waste and limiting the development of miniaturized electronic products.

[0028] Please see Figures 1 to 3 As shown in the embodiment of this application, a compact terminal strip structure is provided, which includes a strip plate 10 and a plurality of conductive terminals 20, wherein:

[0029] Material strip 10 along the first direction ( Figure 1Extending in the direction of X, a plurality of conductive terminals 20 are fixedly connected at intervals to one side of the strip plate 10 along the first direction, and the plurality of conductive terminals 20 are coplanar with the strip plate 10;

[0030] The conductive terminal 20 includes a connecting arm 21, a first lever arm 22, and a second lever arm 23. The first lever arm 22 is composed of a welding section 220 and a first inclined section 221. The welding section 220 is fixedly connected to the strip plate 10. The first end of the first inclined section 221 is fixedly connected to the first end of the connecting arm 21. The second end of the first inclined section 221 is fixedly connected to the first end of the welding section 220. The second end of the first inclined section 221 is higher than the first end of the first inclined section 221. A first accommodating space 24 is formed above the first inclined section 221 and the connecting arm 21.

[0031] The second lever arm 23 is composed of a second inclined segment 230 and an elastic segment 231. The first end of the second inclined segment 230 is fixedly connected to the second end of the connecting arm 21, and the second end of the second inclined segment 230 is fixedly connected to the first end of the elastic segment 231. The first end of the second inclined segment 230 is higher than the second end of the second inclined segment 230, and a second accommodating space 25 is formed above the second inclined segment 230.

[0032] Several conductive terminals 20 are aligned in the same direction along a first direction. The welding section 220 of the conductive terminal 20 of the subsequent process is located in the first accommodating space 24 of the conductive terminal 20 of the adjacent preceding process. The first inclined section 221 of the conductive terminal 20 of the subsequent process is located in the second accommodating space 25 of the conductive terminal 20 of the adjacent preceding process.

[0033] By providing a first inclined section 221 on the conductive terminal 20 to form a first accommodating space 24 for accommodating the welding section 220 of the adjacent conductive terminal 20 in the subsequent process, and providing a second inclined section 230 to form a second accommodating space 25 for accommodating the first inclined section 221 of the adjacent conductive terminal 20 in the subsequent process, it is possible to nest the terminals when they are arranged, thereby reducing the terminal spacing, improving the compactness of the terminal arrangement, and reducing material waste.

[0034] In one embodiment, the first inclined segment 221 and the second inclined segment 230 have the same inclination angle to reduce the gap between the first inclined segment 221 and the second inclined segment 230 in the second accommodating space 25 of the adjacent front passage.

[0035] By setting the first inclined segment 221 and the second inclined segment 230 to have the same inclination angle, the first inclined segment 221 of the subsequent conductive terminal 20 is made to be close enough to the second inclined segment 230 of the adjacent preceding conductive terminal 20, thereby improving the utilization rate of the second accommodating space 25, minimizing the gap between the conductive terminals 20, and improving the tightness of the arrangement.

[0036] In one embodiment, the connecting arm 21 is disposed along a first direction, and the welding section 220 is parallel to the connecting arm 21.

[0037] By arranging the welding section 220 and the connecting arm 21 in parallel, the distance between the welding section 220 of the subsequent conductive terminal 20 and the connecting arm 21 of the adjacent conductive terminal 20 in the previous stage is reduced, thereby improving the utilization rate of the first accommodating space 24, minimizing the gap between the conductive terminals 20, and increasing the tightness of the arrangement.

[0038] In one embodiment, the first lever arm 22 further includes a welding foot 222, the bottom of which is fixedly connected to the second end of the welding segment 220, and an arc-shaped surface 2220 is provided at the connection between the welding foot 222 and the second end of the welding segment 220.

[0039] By setting an arc-shaped surface 2220 at the connection between the welding foot 222 and the welding section 220, the welding foot 222 of the subsequent process is closer to the first inclined section 221 in the first accommodating cavity 24 of the adjacent conductive terminal 20 of the preceding process, which further reduces the gap between the conductive terminals 20 and improves the space utilization rate.

[0040] In one embodiment, a retaining portion 26 is fixedly connected to the lower end of the connecting arm 21. The retaining portion 26 extends downward in the vertical direction and is configured to be fixedly connected to an external insulating component so as to drive the conductive terminal 20 to be fixedly connected to the external insulating component. The elastic segment 231 is inclined downward toward the retaining portion 26.

[0041] By setting the elastic segment 231 downward and inclined towards the vertical holding part 26, the elastic deformation capability is improved, the utilization efficiency of vertical space is improved, and it is easier for adjacent conductive terminals 20 to approach each other, further improving the tightness of the arrangement of conductive terminals 20.

[0042] In one embodiment, a plurality of conductive terminals 20 are evenly spaced along a first direction.

[0043] By arranging the conductive terminals 20 evenly at intervals along the first direction, the balance of the material strip structure is ensured, the consistency of automated production is improved, and production efficiency is increased.

[0044] In one embodiment, the strip plate 10 is provided with a plurality of coplanar extensions facing the conductive terminal 20, and the end of each extension extends to form a connecting plate 11, which is fixedly connected to a preset position on the upper end of the welding section 220.

[0045] Specifically, the connecting plates 11 are evenly spaced along the first direction.

[0046] By providing an extension on the strip plate 10 to form a fixed connection between the connecting plate 11 and the welding section 220, the strength of the connection between the strip plate 11 and the conductive terminal 20 is enhanced, ensuring that the conductive terminal 20 remains stable and does not deform during conveying and processing.

[0047] In one embodiment, a pre-break line 110 is provided at the connection between the connecting plate 11 and the upper end of the welding section 220 along the first direction.

[0048] By setting a pre-cut wire 110 at the connection between the connecting plate 11 and the welding section 220, the detachability of the terminal is improved, which facilitates subsequent processing, assembly or maintenance and improves production efficiency.

[0049] In one embodiment, the strip plate 10 and a plurality of conductive terminals 20 are integrally stamped.

[0050] By manufacturing the strip plate 10 and conductive terminals 20 using an integrated stamping process, the production process is simplified, production efficiency is improved, and the overall structural strength of the strip is enhanced.
