Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric connector manufacturing, in particular to a female socket of a wire-to-board connector. Background Art
[0002] A wire-to-board connector is a device used to connect circuit boards to wires. It uses a male and female connector to achieve the electrical connection between the circuit board and the cable. Wire-to-board connectors are used in a variety of applications, including consumer electronics like televisions and computers, as well as industrial applications such as automotive and avionics.
[0003] Wire-to-board connectors are generally composed of a male and female parts, wherein the female part is mainly composed of an insulating rubber seat, a terminal assembly, and a cable. The insulating rubber seat is formed by snapping a plastic body and a rear cover. The terminal assembly is composed of a plurality of terminals inserted into the plastic body. Multiple cables cross the rear cover and are held one by one by the terminals and electrically conductive. However, the female part with such a design structure has extremely poor waterproof performance. Specifically, water or water vapor inevitably penetrates the inner cavity of the female part through the assembly gap formed between the cable and the rear cover, or through the assembly gap formed between the plastic body and the rear cover, thereby affecting the stability and reliability of the electrical conductivity between the PCB board and the cable, and is bound to affect the actual application effect of the wire-to-board connector. Therefore, technical personnel are urgently needed to solve the above problems. Utility Model Content
[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify the design after years of R&D experience by technicians in this industry, which ultimately led to the emergence of the wire-to-board connector socket.
[0005] In order to solve the above-mentioned technical problems, the utility model relates to a wire-to-board connector mother seat, including an insulating rubber seat, a terminal assembly and a cable. The insulating rubber seat is formed by buckling a plastic body and a rear cover. The terminal assembly is composed of a plurality of terminals assembled into a whole with the plastic body in a rectangular array. The rear side wall of the plastic body extends forward to form a plurality of insertion holes for the terminals to be installed. A plurality of cables cross the rear cover and are held by the terminals one by one and electrically conductive. The rear cover is formed with rear through holes for the terminals to pass through. Furthermore, the wire-to-board connector mother seat also includes a plastic water barrier. The plastic water barrier is formed with a plurality of front through holes for the cables to pass through. When the wire-to-board connector mother seat is assembled, the plastic water barrier is pressed against the plastic body due to the lateral pressure from the rear cover and undergoes elastic deformation, so that the circumferential side walls of each cable are subjected to the elastic wrapping force from the plastic water barrier.
[0006] As a further improvement of the technical solution disclosed in the present utility model, opposite to the front through hole, the front side wall of the plastic water-blocking component extends forward to form a plurality of front waterproof reinforcement extensions, and the rear side wall of the plastic water-blocking component extends backward to form a plurality of rear waterproof reinforcement extensions. Opposite to the insertion hole, the rear side wall of the plastic body extends forward to form a front extrusion groove for inserting the front waterproof reinforcement extensions. Opposite to the rear through hole, the front side wall of the rear cover plate extends backward to form a rear extrusion groove for inserting the rear waterproof reinforcement extension. In the process of the rear cover plate performing displacement movement toward the plastic body to achieve top contact, the front waterproof reinforcement extension and the rear waterproof reinforcement extension extend into the front extrusion groove and the rear extrusion groove respectively, and the front waterproof reinforcement extension and the rear waterproof reinforcement extension undergo elastic shrinkage deformation due to the lateral extrusion force.
[0007] As a further improvement of the technical solution disclosed in the present invention, the outer diameter of the front waterproof reinforcement extension shows a decreasing trend from the back to the front. The outer diameter of the rear waterproof reinforcement extension shows a decreasing trend from the front to the back.
[0008] As a further improvement to the technical solution disclosed in this utility model, the female wire-to-board connector further includes a silicone waterproof ring. This silicone waterproof ring is fitted over the circumferential sidewalls of the plastic body and elastically deforms due to the lateral pressure from the male wire-to-board connector. This fills and seals the mating gap between the female wire-to-board connector and the male wire-to-board connector when mated.
[0009] As a further improvement of the technical solution disclosed in the present invention, the outer wall of the plastic body continues to extend outward around its circumference to form an accommodating groove for accommodating the silicone waterproof ring.
[0010] As a further improvement of the technical solution disclosed in the present invention, sealing grooves are formed on the front and rear side walls of the silicone waterproof ring and are arranged in opposite positions.
[0011] In practical applications, the wire-to-board connector socket disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:
[0012] 1) During the workshop assembly phase, after the wire-to-board connector female base is assembled, the plastic water-blocking component undergoes elastic deformation due to the combined extrusion force from the plastic body and the rear cover. Each front through-hole is able to undergo a necking deformation to tightly wrap the corresponding cable, and the assembly gap formed between the plastic body and the rear cover is also effectively filled and sealed, thereby effectively preventing external water or water vapor from invading the inner cavity of the wire-to-board connector female base along the cable or the assembly gap formed between the plastic body and the rear cover. The waterproof performance of the wire-to-board connector female base is greatly improved;
[0013] 2) Due to its material properties, the plastic water-blocking component has good plasticity and resilience, which is conducive to achieving tight wrapping of the circumferential side walls of the cable and effective sealing of the assembly gap formed between the plastic body and the rear cover. It also has extremely low requirements for the molding position accuracy and dimensional accuracy of the front through-hole, which is conducive to reducing the molding difficulty and molding cost of the plastic water-blocking component.

DETAILED DESCRIPTION
[0031] In the description of the present invention, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0032] The following is a further detailed description of the present invention in conjunction with specific embodiments. Figure 2 、 3As shown in Figures 4 and 5, the female socket of the wire-to-board connector is mainly composed of several parts, such as an insulating rubber seat 1, a terminal assembly 2, a cable 3 and a plastic water-blocking component 4. Among them, the insulating rubber seat 1 is formed by snapping together a plastic body 11 and a rear cover 12. The terminal assembly 2 is composed of a plurality of terminal blocks 21 assembled into one body with the plastic body 11 in a rectangular array. Correspondingly, the rear side wall of the plastic body 11 extends forward to form a plurality of insertion holes 111 for the terminal blocks 21 to be installed. A plurality of cables 3 cross the rear cover 12, and their ends are held by the terminal blocks 21 one by one and are electrically conductive. The rear cover 12 is formed with a rear through hole 121 for the terminal blocks 21 to pass through. The plastic water-blocking component 4 is formed with a plurality of front through holes 41 (such as Figure 7-12 ).
[0033] In actual application, when the wire-to-board connector socket is assembled, the plastic water-blocking component 4 is pressed against the plastic body 11 due to the lateral pressure from the rear cover 12 and undergoes elastic deformation, so that the circumferential side walls of each cable 3 are subjected to the elastic wrapping force from the plastic water-blocking component 4.
[0034] During the workshop assembly stage, when the female base of the wire-to-board connector is assembled, the plastic water-blocking member 4 undergoes elastic deformation due to the combined extrusion force from the plastic body 11 and the rear cover 12, and each front through-hole 41 is able to undergo a necking deformation to tightly wrap the cable 3 inserted therein, and the assembly gap formed between the plastic body 11 and the rear cover 12 is also effectively filled and sealed, thereby effectively preventing external water or water vapor from invading the inner cavity of the female base of the wire-to-board connector along the cable 3 or the assembly gap formed between the plastic body 11 and the rear cover 12, thereby greatly improving the waterproof performance of the female base of the wire-to-board connector;
[0035] Furthermore, it should be noted that due to its material properties, the plastic water-blocking component 4 has good plasticity and resilience, which is conducive to achieving tight wrapping of the circumferential side walls of the cable 3 and effective sealing of the assembly gap formed between the plastic body 11 and the rear cover plate 12, and has extremely low requirements on the molding position accuracy and dimensional accuracy of the front through hole 41, which is conducive to reducing the molding difficulty and molding cost of the plastic water-blocking component 4.
[0036] like Figure 11 、 12 As shown in FIG, opposite to the front through hole 41, the front side wall of the plastic water blocking member 4 extends forward to form a plurality of front waterproof reinforcement extensions 42, and the rear side wall of the plastic water blocking member 4 extends backward to form a plurality of rear waterproof reinforcement extensions 43. Figure 7-10As shown in FIG, opposite to the insertion hole 111, the rear side wall of the plastic body 11 extends forward to form a front extrusion groove 112 for inserting the front waterproof reinforcement extension 42. Opposite to the rear through hole 121, the front side wall of the rear cover plate 12 extends backward to form a rear extrusion groove 122 for inserting the rear waterproof reinforcement extension 43. During the assembly stage in the workshop, when the rear cover 12 performs a displacement movement toward the plastic body 11 to achieve top contact, the front waterproof reinforcement extension 42 and the rear waterproof reinforcement extension 43 are respectively forced to be squeezed into the front extrusion groove 112 and the rear extrusion groove 122. The front waterproof reinforcement extension 42 and the rear waterproof reinforcement extension 43 undergo elastic shrinkage deformation due to the lateral extrusion force, and the corresponding cable 3 is tightly wrapped. At the same time, the assembly gap formed between the plastic body 11 and the rear cover 12 is also tightly filled and sealed by the plastic water-blocking component 4.
[0037] As Figure 6 As shown in the figure, the busbars of the front waterproof reinforcement extension 42 and the rear waterproof reinforcement extension 43 are both inclined. Specifically, the outer diameter of the front waterproof reinforcement extension 42 shows a decreasing trend along the direction from back to front. The outer diameter of the rear waterproof reinforcement extension 43 shows a decreasing trend along the direction from front to back. In this way, on the one hand, it is conducive to the rapid alignment and assembly of the plastic water-blocking component 4 relative to the plastic body 11 and the rear cover 12, and it is conducive to ensuring that the plastic water-blocking component 4 effectively fills and seals the assembly gap formed between the plastic body 11 and the rear cover 12; on the other hand, thanks to the special-shaped design structure, the cable 3 has a longer wrapping distance relative to the plastic water-blocking component 4, which is conducive to further improving the waterproof performance of the wire-to-board connector female socket.
[0038] According to industry experience, water or water vapor can not only invade into the interior of the wire-to-board connector female seat along the cable 3 or the assembly gap formed between the plastic body 11 and the rear cover 12, but also partially invade through the assembly gap between the wire-to-board connector female seat and the wire-to-board connector male seat, which will inevitably reduce the upper limit of the improvement of the waterproof performance of the wire-to-board connector female seat. In view of this, as a further optimization of the above technical solution, such as Figure 2 、 4 As shown in , 5, the female socket of the wire-to-board connector is further provided with a silicone waterproof ring 5. Figure 13 、 14 15 together illustrate the structure of the silicone waterproof ring 5. Around its circumference, the outer wall of the plastic body 11 continues to extend outward to form an accommodating groove 113 (such as Figure 7As shown in ). The silicone waterproof ring 5 is installed in the accommodating groove 113 and circumferentially holds the plastic body 11. In this way, during the operation of inserting and assembling the female and male sockets of the wire-to-board connector, the silicone waterproof ring 5 is elastically deformed due to the lateral pressure from the male socket of the wire-to-board connector, and the mating gap formed between the female and male sockets of the wire-to-board connector after the insertion is completed is filled and blocked (as shown in ). Figure 1 ).
[0039] Finally, it should be noted that Figure 13-15 As shown in the figure, the front and rear sidewalls of the silicone waterproof ring 5 are respectively formed with a front sealing groove 51 and a rear sealing groove 52, and the two are positioned in opposite positions. This not only helps ensure that the front and rear sidewalls of the silicone waterproof ring 5 are tightly fitted with the female and male sockets of the wire-to-board connector, but also greatly improves the actual sealing effect of the silicone waterproof ring 5. It also significantly enhances the pressure resistance of the silicone waterproof ring 5.
[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
