Description

Technical Field

[0001] The utility model relates to the technical field of heavy-load rectangular connectors, in particular to a heavy-load rectangular connector socket and a rectangular connector capable of being installed with strong torque. Background Art

[0002] Heavy-duty rectangular connector is an electrical component that is mainly used to connect and disconnect signals and currents in circuits. It consists of a plug and a socket, and the mating surface is rectangular in shape. It can connect multiple signal and power lines to achieve electrical signal and power transmission.

[0003] The heavy-duty rectangular connector socket is mainly composed of a plastic outer shell and an internal multi-core insulating body. The function of the plastic outer shell is to accommodate and fix the multi-core insulating body to ensure its stability during operation. The rectangular connector socket is usually installed on other components or devices with the help of the connecting plate on it and fixings such as bolts.

[0004] The connection plate on the existing heavy-duty rectangular connector socket is relatively thin. Under the strong torque of fasteners (such as bolts), the mounting hole of the connection plate is prone to depression and cracking, affecting the stability and reliability of the electrical connection. This cracking problem may occur not only during the fixed installation of the socket, but also during daily use, especially in the case of long-term frequent plugging and unplugging or mechanical vibration, fatigue cracking of the connection plate may also occur.

[0005] In order to avoid this situation during installation, the conventional practice is to use special tools (such as torque wrenches or torque screwdrivers) to help operators control the tightening force of the bolts to avoid excessive force on the connecting plate during installation and damage to the connector. However, in most occasions and conditions, operators use ordinary wrenches or screwdrivers to control the tightening force of fasteners by feel, so it is easy to cause the connector to be overstressed and cracked, especially in the installation of heavy-duty rectangular connectors.

[0006] In order to solve this problem, the existing technology usually adopts the method of increasing the thickness of the connecting plate or using a metal bracket to solve this problem. However, these methods have certain shortcomings: although increasing the thickness of the connecting plate can improve the strength of the connecting plate, it will increase the overall material usage and increase the weight of the socket; and using a metal bracket to replace the connecting plate, although it solves the cracking problem, it will increase the number of parts, make installation inconvenient, and make the socket structure complicated, and the manufacturing cost increases accordingly. Utility Model Content

[0007] In view of the problems existing in the above-mentioned prior art, the utility model proposes a heavy-duty rectangular connector socket and an electrical connector thereof which have simple structure, high torsion resistance, high strength, less material, low cost and long life.

[0008] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0009] A heavy-duty rectangular connector socket capable of withstanding strong torque installation comprises a socket body, an outer wall of which is provided with a connecting plate, a mounting hole is provided on the connecting plate, an additional hole is provided on the mounting hole opening, and an anti-torsion flange is provided on the opening of the mounting hole.

[0010] Preferably, the outer diameter of the anti-torsion flange is larger than the outer diameter of the fastener.

[0011] Preferably, the outer diameter of the anti-torsion flange is greater than 5% of the outer diameter of the fastener.

[0012] Preferably, the thickness of the anti-torsion flange is greater than the thickness of the connecting plate by 20%.

[0013] Preferably, there are 2 to 6 mounting holes on the connecting plate.

[0014] Preferably, the socket is made of insulating material.

[0015] A rectangular connector comprises the heavy-load rectangular connector socket capable of withstanding strong torque installation.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The anti-torsion flange is set at the opening of the socket mounting hole, which increases the rigidity and strength of the mounting hole, improves the mounting hole's ability to withstand the torque of the fastener, and avoids cracking caused by excessive torque when installing the locking piece. In addition, the flange also improves the installation positioning effect, making the socket more stable and less likely to loosen during installation. At the same time, the flange structure provides a larger area and more uniform force distribution, effectively dispersing and withstanding the stress and torque generated during installation, reducing the friction and wear between the fastener and the mounting hole, and extending the service life of the socket and connector.

[0018] 2. Compared with the overall thickened connection plate socket structure, the utility model only increases the thickness locally around the mounting hole, which can prevent the connection plate from cracking due to excessive installation torque, and has the beneficial effects of saving materials, reducing weight and reducing costs.

[0019] 3. Compared with the socket structure of the metal connecting plate, the utility model has the advantages of fewer parts, simple structure, convenient installation and fixation, light weight, low cost and good stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0025] Embodiment 1:

[0026] A heavy-duty rectangular connector socket capable of withstanding strong torque installation, wherein the socket body 1 is made of insulating material. A connecting plate 2 is fixedly arranged on the outer wall of the socket body 1, and a mounting hole 3 is arranged on the connecting plate 2, which is used to fix or connect the socket to other components (such as a circuit board, a chassis or a cabinet) so as to achieve a stable installation through bolts or other fasteners.

[0027] The opening of the mounting hole 3 is provided with an anti-torsion flange 4, which increases the thickness of the opening of the mounting hole, improves the torque bearing capacity and heavy-load installation performance of the connector, makes the connector adaptable to high-torque and heavy-load application scenarios, and improves the stability and reliability of the circuit connection. Specifically:

[0028] (1) Increasing the thickness of the mounting hole directly enhances the strength and rigidity of this area. In this way, when fasteners (such as bolts) apply torque, these thickened areas can better resist deformation and disperse the stress generated by the torque force. Compared with connectors without flange structures, the thickened areas significantly reduce the concentrated effect of torque on a single point, thereby reducing the risk of cracking or damage.

[0029] (2) The specific geometric shape of the flange structure not only increases the force-bearing area, but also optimizes the force distribution. The geometric design can make the torque force more evenly distributed on the flange, avoiding local concentration of stress. This uniform force distribution helps to reduce the local stress peak of the connecting plate when it is subjected to torque, thereby improving the stability and reliability of the entire structure.

[0030] (3) The flange structure also enhances the connection stability between the fastener and the connector by providing a larger contact area. A larger contact area means higher friction, which helps prevent the fastener from loosening under vibration or impact. Therefore, the flange structure not only improves torque bearing capacity, but also enhances stability and durability during heavy-load installation.

[0031] In order to further improve the structural strength of the mounting hole and ensure that the mounting hole will not be depressed or cracked due to stress concentration when subjected to the torque force applied by the fastener, the outer diameter of the anti-torsion flange 4 should be larger than the outer diameter of the fastener. When the fastener is tightened and self-locked, it will exert an outward force on the wall of the mounting hole. If the structural strength of the mounting hole is insufficient, this force may cause the hole to be depressed or cracked, thereby affecting the stability and electrical performance of the socket. By providing a flange on the mounting hole and making its outer diameter larger than the outer diameter of the fastener, this outward force can be effectively dispersed and resisted, and the structural strength of the mounting hole can be improved, thereby avoiding the problem of cracking caused by excessive torque.

[0032] Specifically, setting the outer diameter of the torque flange 4 to be 5% larger than the outer diameter of the fastener will achieve better structural strength and better anti-torque effect.

[0033] Embodiment 2:

[0034] In this embodiment, the thickness of the flange 4 is greater than 20% of the thickness of the connecting plate to ensure that the socket connecting plate has sufficient structural strength to withstand greater installation torque and vibration impact during use.

[0035] Embodiment 3:

[0036] The mounting holes 2-1 on the connecting plate can be arranged in pairs of 2 to 6 according to different connection requirements, so that the socket connecting plate is more evenly stressed, the installation is more reliable and stable, and the anti-cracking effect is better.
