Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically a double-row connector. Background Technology
[0002] Connectors, also called connectors, sockets, and connectors, generally refer to electrical connectors. They are devices that connect two active devices; the male and female terminals can transmit information or current after contact. They are widely used in wire harnesses, PCB boards, and other equipment.
[0003] When existing wire harnesses are assembled with dual-row connectors, the contact terminals are usually embedded and fixed inside the connector. Then the lead-out part of the wire harness is connected to the contact terminal. However, the diameter of the lead-out wire is usually small, so the connection area with the contact terminal is also small. When the wire harness is pulled, the soldered and crimped parts of the lead-out wire and the contact terminal will be subjected to tension, which may cause the fixing point to break or fall off. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a double-row connector to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-row connector, comprising a connector body, wherein a first clamping block and a second clamping block are respectively connected to the outer surface of the connector body; and insert plates are fixed on both sides of the top of the first clamping block, and a first curved groove is provided on the outer surface of the first clamping block; slots are provided on both sides of the bottom of the second clamping block, and a second curved groove is provided on the outer surface of the second clamping block; a threaded sleeve is embedded in the top of the second clamping block, and a bolt passes through the top of the threaded sleeve.
[0006] By adopting the above technical solution, after the wire harness is installed, the workers combine the first and second clamping plates and then install them into the connector body. The bolts are then tightened to prevent the second clamping plate from falling off, and the second clamping plate is pressed tightly against the first clamping plate to hold the wire harness firmly. The first and second clamping plates compress the wire harness, reducing the tension on the wire harness lead-out portion, thereby increasing structural stability and effectively reducing the occurrence of wire harness lead-out portion desoldering and breakage. Simultaneously, the second clamping plate is connected to the first clamping plate through inserts and slots to prevent the first clamping plate from falling off. Furthermore, the first and second curved grooves form an arc on the sides of the first and second clamping blocks, allowing the wire harness to bend at a larger angle instead of a 90-degree bend or a small angle bend, reducing the occurrence of wire harness breakage.
[0007] Furthermore, the insert plate and the slot are interference-fitted, and the first clamping block is detachably connected to the second clamping block through the insert plate and the slot.
[0008] By adopting the above technical solution, the bolts are tightened to prevent the second clamp from falling off, and the second clamp is pressed to make the second clamp fit tightly with the first clamp and hold the wire harness. The first and second clamps press the wire harness together, reducing the tension on the wire harness lead-out part, thereby increasing the structural stability and effectively reducing the occurrence of phenomena such as wire harness lead-out part desoldering and breakage. At the same time, the second clamp is connected to the first clamp through the insert plate and slot to prevent the first clamp from falling off.
[0009] Furthermore, the first clamping block and the insert plate are both made of ABS material, and the first clamping block, the insert plate and the first curved groove are all integrally molded by injection molding.
[0010] By adopting the above technical solution, the first clamping block, insert plate and first curved groove are produced by integral injection molding, resulting in a stable structure and low cost.
[0011] Furthermore, the second clamping block is made of ABS material, and the second clamping block, the slot, and the second curved groove are all integrally molded by injection molding.
[0012] By adopting the above technical solution, the second clamping block, slot, and second curved groove are produced by integral injection molding, resulting in a stable structure and low cost.
[0013] Furthermore, both the first and second curved grooves have an arc-shaped side.
[0014] By adopting the above technical solution, the first and second bends form an arc on the sides of the first and second clamping blocks, allowing the wire harness to bend at a larger angle when bent, rather than bending at a 90-degree angle or a small angle, thus reducing the occurrence of wire harness breakage.
[0015] Furthermore, the bolt is threadedly connected to the connector body, and both the first clamping block and the second clamping block are detachably connected to the connector body.
[0016] By adopting the above technical solution, the workers combined the first and second clamping plates and then installed them into the connector body. Afterwards, they tightened the bolts to prevent the second clamping plate from falling off.
[0017] Furthermore, the connector body has multiple terminal mounting slots inside, and the multiple terminal mounting slots are divided into two groups, with the two groups of terminal mounting slots being mirror images of each other.
[0018] By adopting the above technical solution, after the connector body is produced, the terminals are installed into the terminal mounting slots and the lead-out part of the wire harness is installed into the terminals, thereby completing the production and assembly of traditional connectors.
[0019] Furthermore, after surface treatment, the threaded sleeve is fixed to the surface-treated second clamping block by applying epoxy resin adhesive.
[0020] By adopting the above technical solution, the threaded sleeve can be easily assembled and fixed on the top of the second clamping block, thereby avoiding the phenomenon of the threaded sleeve loosening and falling off.
[0021] Furthermore, the top of the threaded sleeve is hexagonal.
[0022] By adopting the above technical solution, the hexagonal top of the threaded sleeve can prevent the threaded sleeve from rotating, thus avoiding the bolt rotation causing the threaded sleeve to rotate and affecting the structural stability.
[0023] In summary, the present invention has the following main advantages:
[0024] 1. This utility model uses a first clamping plate and a second clamping plate to press the wire harness together, reducing the tension on the wire harness lead-out portion, thereby increasing structural stability and effectively reducing phenomena such as wire harness lead-out portion desoldering and breakage; increasing structural stability reduces the pulling on the lead-out portion.
[0025] 2. This utility model, through the setting of insert plate, slot, threaded sleeve and bolt, allows the first clamp plate and the second clamp plate to be combined and then installed into the connector body after the wire harness is installed. Then, the bolt is tightened to prevent the second clamp plate from falling off, and the second clamp plate is pressed to make the second clamp plate fit tightly with the first clamp plate and hold the wire harness. At the same time, the second clamp plate is connected to the first clamp plate through the insert plate and slot to prevent the first clamp plate from falling off; it is convenient to disassemble and assemble and increases the structural stability.
[0026] 3. This utility model, through the setting of the first and second curved grooves, forms an arc on the sides of the first and second clamping blocks, allowing the wire harness to bend at a larger angle instead of a 90-degree bend or a small angle bend, thus reducing the occurrence of wire harness breakage and facilitating the protection of the wire harness.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of this utility model will be described below based on its overall structure.
[0035] Example 1:
[0036] A dual-row connector, such as Figures 1-5 As shown, the connector includes a connector body 1, with a first clamping block 2 and a second clamping block 3 connected to its outer surface. Insert plates 4 are fixed to both sides of the top of the first clamping block 2, and a first curved groove 8 is provided on the outer surface of the first clamping block 2. Both the first clamping block 2 and the insert plates 4 are made of ABS material, and the first clamping block 2, insert plates 4, and first curved groove 8 are integrally molded by injection molding. Slots 5 are provided on both sides of the bottom of the second clamping block 3, with the insert plates 4 and slots 5 having an interference fit. The first clamping block 2 is detachably connected to the second clamping block 3 via the insert plates 4 and slots 5. A second curved groove 9 is provided on the outer surface of the second clamping block 3, with one side of both the first curved groove 8 and the second curved groove 9 being arc-shaped. The second clamping block 3 is made of ABS material, and the second clamping block 3, slots 5, and second curved groove 9 are integrally molded by injection molding. A threaded sleeve 6 is embedded at the top of the second clamping block 3, and a bolt 7 passes through the top of the threaded sleeve 6. The first clamp 2 and the second clamp 3 are threadedly connected to the connector body 1. Both the first clamp 2 and the second clamp 3 are detachably connected to the connector body 1. After the wire harness is installed, the operator merges the first clamp 2 and the second clamp 3 and then inserts them into the connector body 1. Then, the bolt 7 is tightened to prevent the second clamp 3 from falling off, and the second clamp 3 is pressed to make the second clamp 3 fit tightly against the first clamp 3 and hold the wire harness tightly. The first clamp 3 and the second clamp 4 press the wire harness tightly, reducing the tension on the wire harness lead-out part, thereby increasing the structural stability and effectively reducing the occurrence of wire harness lead-out part desoldering, breakage and other phenomena. At the same time, the second clamp 3 is connected to the first clamp 3 through the insert plate 4 and the slot 5 to prevent the first clamp 3 from falling off. The first bend 8 and the second bend 9 form an arc on the side of the first clamp 2 and the second clamp 3, so that when the wire harness is bent, it can bend at a larger angle, instead of bending at a ninety-degree angle or a small angle, reducing the occurrence of wire harness breakage.
[0037] See Figure 1 and Figure 2In the above embodiment, the connector body 1 has multiple terminal mounting slots 10 inside. The multiple terminal mounting slots 10 are divided into two groups, and the two groups of terminal mounting slots 10 are mirrored. After the connector body 1 is manufactured, the terminals are installed into the terminal mounting slots 10 and the lead-out part of the wire harness is installed into the terminals, thereby completing the production and assembly of the traditional connector.
[0038] Example 2:
[0039] Based on the above embodiment one, structural stability is enhanced by the following settings.
[0040] See Figure 2 and Figure 3 In the above embodiment, after surface treatment, the threaded sleeve 6 is fixed to the surface-treated second clamping block 3 by epoxy resin adhesive. The top of the threaded sleeve 6 is hexagonal, which facilitates the assembly and fixing of the threaded sleeve 6 to the top of the second clamping block 3 and avoids the rotation of the bolt 7 from causing the threaded sleeve 6 to rotate and affecting the structural stability.
[0041] The implementation principle of this utility model is as follows: First, after the connector body 1 is produced, the terminals are installed into the terminal mounting slot 10 and the lead-out part of the wire harness is installed into the terminals, thereby completing the production and assembly of the traditional connector.
[0042] After the wire harness is installed, the workers combine the first and second clamps and then insert them into the connector body 1. The bolts 7 are then tightened to prevent the second clamp from falling off, and the second clamp is pressed tightly against the first clamp to hold the wire harness firmly. The first and second clamps compress the wire harness, reducing the tension on the wire harness lead-out portion, thereby increasing structural stability and effectively reducing the occurrence of wire harness lead-out portion desoldering and breakage. Simultaneously, the second clamp is connected to the first clamp via the insert plate 4 and slot 5 to prevent the first clamp from falling off. Furthermore, the first and second curved grooves 8 and 9 form an arc on the sides of the first clamp block 2 and the second clamp block 3, allowing the wire harness to bend at a larger angle instead of a 90-degree bend or a small angle bend, reducing the occurrence of wire harness breakage.
