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

[0002] Strip connectors are widely used in electrical and electronic systems, and their core function is to provide a stable and reliable electrical connection for circuit boards, equipment or cables.

[0003] In the existing structure of strip connectors, the plastic part is a long plate structure. The plastic part is relatively long, which often leads to the plastic part being easily deformed after injection molding, and the overall deformation of the plastic part is large. This makes the defect cost of existing strip connectors high and unsuitable for mass production. Utility Model Content

[0004] The main purpose of this invention is to propose a strip connector that aims to solve the problems of easy deformation of plastic parts and high cost of defective products in existing strip connectors.

[0005] To achieve the above objectives, the strip connector proposed in this utility model includes a plastic part and multiple conductive terminals. The plastic part is provided with multiple spaced-apart insertion holes, and the multiple conductive terminals are inserted into the insertion holes one by one.

[0006] The plastic part is also provided with a cross structure on one side. The cross structure includes a horizontal structure and multiple vertical grooves. The multiple vertical grooves extend along the height direction of the plastic part and are spaced apart from each other. The vertical grooves are used to separate two adjacent conductive terminals. The horizontal structure extends along the length direction of the plastic part and is connected to the multiple vertical grooves. The horizontal structure is convex or concave relative to the surface of the plastic part.

[0007] In some embodiments, the depth of the vertical groove is 0.4mm-0.6mm.

[0008] In some embodiments, the transverse structure is a horizontal groove, which is recessed relative to the surface of the plastic part, and the horizontal groove communicates with a plurality of the vertical grooves to form a cross groove.

[0009] In some embodiments, the insertion hole includes a guide hole and a fixing hole, the guide hole being connected to the fixing hole, and the guide hole being extended outward.

[0010] In some embodiments, the conductive terminal includes a first pin segment and a second pin segment, the first pin segment and the second pin segment being arranged perpendicularly to each other, and the first pin segment being inserted into the socket to connect with the plastic part.

[0011] In some embodiments, the end of the first pin segment has a pointed structure.

[0012] In some embodiments, the second pin protrudes relative to the bottom of the plastic part.

[0013] In some embodiments, the plastic part includes a first side and a second side, the first side and the second side being disposed opposite to each other, the first side having a cross structure, and the first prong segment passing through the first side and the second side.

[0028] In the existing structure of strip connectors, the plastic part is a long plate structure. The plastic part is relatively long, which often leads to the plastic part being easily deformed after injection molding, and the overall deformation of the plastic part is large. This makes the defect cost of the existing strip connector 100 high, and it is not suitable for mass production.

[0029] This utility model proposes a strip connector 100. Please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment of the present invention, the strip connector 100 proposed by the present invention includes a plastic part 10 and a plurality of conductive terminals 20. The plastic part 10 is provided with a plurality of spaced-apart insertion holes 11, and the plurality of conductive terminals 20 are inserted into the insertion holes 11 one by one.

[0030] The plastic part 10 is also provided with a cross structure 30 on one side. The cross structure 30 includes a horizontal structure 31 and a plurality of vertical grooves 32. The plurality of vertical grooves 32 extend along the height direction of the plastic part 10 and are spaced apart from each other. The vertical grooves 32 are used to separate two adjacent conductive terminals 20. The horizontal structure 31 extends along the length direction of the plastic part 10 and is connected to the plurality of vertical grooves 32. The horizontal structure 31 is either protruding or recessed relative to the surface of the plastic part 10.

[0031] The technical solution of this utility model involves adding a cross structure 30 to one side of the plastic part 10. The cross structure 30 includes a horizontal structure 31 and multiple vertical grooves 32. The multiple vertical grooves 32 extend along the height direction of the plastic part 10 and are spaced apart from each other, serving to separate adjacent conductive terminals 20. The horizontal structure 31 extends along the length direction of the plastic part 10 and connects to the multiple vertical grooves 32. The horizontal structure 31 is either protruding or recessed relative to the surface of the plastic part 10. This arrangement allows the plastic part 10 to undergo controllable elastic deformation in the direction of the vertical grooves 32, while suppressing bending or twisting in other directions. This results in more uniform and controllable overall deformation of the plastic part 10, minimizing the amount of deformation and reducing the defect rate of the strip connector 100, making it suitable for mass production.

[0032] In one embodiment, the slotting alters the stress pattern of the plastic part 10, allowing large-area deformation to be distributed across multiple small regions within the plastic part 10. Each small region deforms independently due to the presence of the vertical slot 32, resulting in a smaller overall deformation of the plastic part 10. That is, the vertical direction of the plastic part 10 gains increased structural stability due to the presence of the vertical slot 32. Thus, when the plastic part 10 is subjected to external force, deformation may primarily concentrate in the direction of the vertical slot 32, while the overall structure of the plastic part 10, due to the segmentation by the vertical slot 32, allows the deformations of each part to cancel each other out or reduce the total deformation.

[0033] Furthermore, during the injection molding process of the plastic part 10, the vertical groove 32 can serve as an "expansion joint" to provide expansion space for the thermal expansion of the rubber material, thereby preventing the plastic part 10 from warping or cracking due to thermal stress and reducing the amount of thermal deformation.

[0034] In one embodiment, the vertical groove 32 is elongated. The plastic part 10 also has a transverse structure 31, which is staggered with the vertical groove 32 to form several cross structures 30. The cross structures 30 form expansion joints in the orthogonal directions, allowing the plastic material to expand and contract freely in both the X and Y directions, preventing warping or cracking due to accumulated thermal stress.

[0035] Optionally, the depth of the vertical groove 32 is 0.4mm-0.6mm. The depth of the vertical groove can be flexibly adjusted. In one embodiment, the depth of the vertical groove 32 is 0.5mm.

[0036] In one embodiment, the transverse structure 31 is a horizontal groove, which is recessed relative to the surface of the plastic part 10. The horizontal groove communicates with a plurality of vertical grooves 32 to form a cross groove.

[0037] The depth of the transverse groove is 0.4mm-0.6mm. In one embodiment, the depth of the transverse groove is 0.5mm. The presence of the transverse groove increases the structural stability of the plastic part 10 in the transverse direction. Thus, when the plastic part 10 is subjected to external force, the deformation may be mainly concentrated in the direction of the transverse and vertical grooves 32, while the overall structure of the plastic part 10, due to the division of the transverse and vertical grooves 32, has its deformations canceling each other out or reducing the total deformation.

[0038] Please see Figure 3 To facilitate the insertion of the conductive terminal 20 into the socket 11, the socket 11 includes a guide hole 110 and a fixing hole 111. The guide hole 110 is connected to the fixing hole 111, and the guide hole 110 is extended outward.

[0039] Please see Figure 1 and Figure 2The conductive terminal 20 includes a first pin segment 21 and a second pin segment 22, which are arranged perpendicularly to each other. The first pin segment 21 is inserted into the socket 11 to connect with the plastic part 10.

[0040] The plastic part 10 is equipped with two rows of conductive terminals 20, and the number of conductive terminals 20 in each row can be 8, 9, 10, etc. Each conductive terminal 20 is provided with a first pin segment 21 and a second pin segment 22. The first pin segment 21 and the second pin segment 22 are arranged perpendicularly. The first pin segment 21 is inserted into the insertion hole 11 of the plastic part 10 so that the conductive terminal 20 is connected to the plastic part 10.

[0041] To facilitate insertion into the socket 11, the end of the first pin segment 21 has a pointed structure 210.

[0042] In one embodiment, the second pin segment 22 protrudes relative to the bottom of the plastic part 10.

[0043] In one embodiment, the plastic part 10 includes a first side and a second side, the first side and the second side are disposed opposite to each other, the first side is provided with a cross structure 30, and the first pin segment 21 passes through the first side and the second side.

[0044] Furthermore, the plastic part 10 includes a third side and a fourth side, which are arranged opposite to each other. Both the third side and the fourth side are provided with a fixing part 12 extending outward. The fixing part 12 is provided with a boss 13, which protrudes towards the second pin segment 22 of the conductive terminal 20. The boss 13 is provided with a vent hole 130.

[0045] The boss 13 is provided with a vent 130 for venting during injection molding of the plastic part 10.

[0046] In one embodiment, the edge of the fixing part 12 is a ramp structure 14. The third and fourth sides of the plastic part 10 are both provided with ramp structures 14 so that the cold glue can flow smoothly during the molding of the plastic part 10, thereby reducing the glue flow resistance and reducing the deformation of the plastic part 10.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
