Description

Technical Field

[0001] This utility model relates to a connector structure, specifically a connector structure that is not easily cracked, and belongs to the field of connector technology. Background Technology

[0002] Connectors, as crucial interconnecting components in electronic devices, are widely used in communications, automotive, and consumer electronics, and their reliability directly impacts the stability of the entire system. In traditional connector structures, the insulating base and internal metal components (such as the middle clip and terminals) are typically joined using injection molding.

[0003] However, due to the difference in thermal expansion coefficients between metal and plastic materials, internal stress concentration can easily occur at the interface under temperature changes or mechanical stress, leading to problems such as cracking of the insulating base or separation of the metal parts from the plastic, especially in environments with repeated insertion and removal or vibration. In existing technologies, increasing wall thickness or adding reinforcing ribs is commonly used to improve the structural strength of connectors, but these methods increase the product size, making it difficult to meet the needs of miniaturization and high-density installation. Furthermore, some connectors attempt to incorporate simple slot structures inside the insulating base to enhance insert fixation, but due to unreasonable slot layout or monotonous shapes, uneven material flow during injection molding can still easily result in insufficient bonding strength and poor crack resistance.

[0004] Therefore, there is an urgent need for a new type of connector structure that can improve the bonding strength between the metal parts and the insulating base through optimized internal design, thereby effectively suppressing cracking. Utility Model Content

[0005] The purpose of this utility model is to provide a connector structure that is not prone to cracking in order to solve the above problems. By opening the feeding groove, the strength of the secondary molding is increased, thereby improving the tensile force between the upper and lower parts. By opening two first feeding holes and two rows of second feeding holes, the structural strength of the secondary molding product is enhanced and cracking is prevented.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a connector structure that is not prone to cracking includes an insulating base, one end of which is provided with two first feeding holes, one end of which is provided with two rows of second feeding holes, a middle clamping plate installed inside the insulating base, and multiple terminals equally distributed on both sides of one end of the insulating base, and one end of the middle clamping plate is provided with two feeding grooves.

[0007] Preferably, extension plates are provided on both sides of the end of the middle clip, and the extension plates have an "L" shaped structure.

[0008] Preferably, a through groove is provided at the center line of one end of the middle clip, and the through groove has a rectangular structure.

[0009] Preferably, both the first feeding hole and the second feeding hole are rectangular structures, and the feeding groove is located at the edge of the middle clamping piece.

[0010] Preferably, the insulating base has two slots at its end edge, and one end edge of the slot has a certain slope.

[0011] Preferably, two positioning rods are vertically connected to the bottom side of the end of the insulating base, and the bottom of the positioning rods has a conical structure.

[0012] Preferably, the outer side of the end of the insulating base is provided with multiple positioning grooves, and the positioning grooves are rectangular in structure.

[0013] The beneficial effects of this utility model are: by setting an insulating seat, the centering clip and multiple terminals can be installed, which facilitates subsequent insertion and conduction with the female socket; by opening the feeding groove, the strength of the secondary molding is increased, thereby improving the upper and lower holding force; by opening two first feeding holes and two rows of second feeding holes, the product structure strength of the secondary molding is enhanced and cracking is prevented.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3As shown, a connector structure that is not prone to cracking includes an insulating base 1. One end of the insulating base 1 is provided with two first feeding holes 4 and two rows of second feeding holes 5. A middle clamping plate 2 is installed inside the insulating base 1. Multiple terminals 3 are installed on both sides of one end of the insulating base 1 at equal intervals. One end of the middle clamping plate 2 is provided with two feeding grooves 6.

[0018] As a technical optimization of this utility model, extension plates 8 are provided on both sides of the end of the middle clamping piece 2. The extension plates 8 have an "L" shaped structure. By installing the extension plates 8, it is convenient to extend into the interior of the insulating base 1, so as to reinforce and limit the middle clamping piece 2.

[0019] As a technical optimization of this utility model, a through groove 7 is provided at the center line of one end of the middle clamping piece 2. The through groove 7 has a rectangular structure. By opening the through groove 7, the overall weight of the middle clamping piece 2 is reduced, and the structure of the insulating base 1 is stabilized.

[0020] As a technical optimization of this utility model, both the first feeding hole 4 and the second feeding hole 5 are rectangular structures, and the feeding groove 6 is located at the edge of the middle clamping piece 2, which helps to improve the stability of the insulating seat 1 and makes the whole structure more aesthetically pleasing.

[0021] As a technical optimization of this utility model, two slots 11 are provided at the edge of the end of the insulating base 1. One edge of the slot 11 has a certain slope. The slots 11 facilitate the locking connection between the insulating base 1 and the equipment shell.

[0022] As a technical optimization of this utility model, two positioning rods 10 are vertically connected to the bottom side of the end of the insulating base 1. The bottom of the positioning rod 10 is a conical structure. The installation of the positioning rod 10 facilitates the stable engagement of the insulating base 1 with the outer shell and plays a role in positioning and preventing detachment.

[0023] As a technical optimization of this utility model, the outer side of the end of the insulating seat 1 is provided with multiple positioning grooves 9. The positioning grooves 9 are rectangular structures. By opening the positioning grooves 9, the insulating seat 1 can be positioned and locked stably when installed with the equipment, thus preventing the insulating seat 1 from loosening.

[0024] In use, the insulating base 1 and the middle clamp 2 are first injection molded, and the middle clamp 2 is stably installed at the center of the inner side of the insulating base 1 to enhance the structural strength of the insulating base 1. Then, multiple rows of terminals 3 are installed inside the insulating base 1, with one side of the terminals 3 exposed to facilitate subsequent connection with the internal metal spring of the female base for signal transmission. During the injection molding of the insulating base 1, the opening of the material groove 6 increases the strength of the secondary molding, thereby improving the upper and lower holding force. The opening of two first material holes 4 and two rows of second material holes 5 enhances the structural strength of the secondary molding product and prevents cracking. Finally, the insulating base 1 is stably installed with the equipment housing through the cooperation of the slot 11, the positioning groove 9 and the positioning rod 10 for easy subsequent use.
