Description
Technical Field
[0001] This utility model relates to the field of electrical connector manufacturing technology, and in particular to an electrical connector assembly. Background Technology
[0002] Electrical connector assemblies are general-purpose connection devices widely used in electronics, electrical appliances, and instrumentation, primarily responsible for transmitting current or signals. An electrical connector assembly consists of wire-end electrical connectors and board-end electrical connectors.
[0003] In terms of the current state of technology, such as Figure 1 , 2 As shown, both the power pin and signal pin at the wire end are inserted into the wire end plastic body, and the two power pins are symmetrically arranged on both sides of the signal pin insertion area. The power pin and signal pin at the board end both use a tail cover plate molded on the board end plastic body as their insertion base, and both extend into the cavity of the board end plastic body by a set length. When the wire end electrical connector is fully mated to the board end electrical connector, the signal pin and the board end signal pin mat together to transmit signals, while the power pin and the board end power pin mat together to transmit electrical energy. The wire end plastic body must be inserted into the cavity of the board end plastic body. In practical applications, the most common electrical connector assemblies on the market have the following problems: 1) The design size of both the wire end plastic body and the board end plastic body is relatively large. The reason for this is that the two power pins need to occupy a large insertion area, that is, areas must be reserved on both sides of the signal pin insertion area to accommodate the power pins. The two board-end power PINs need to occupy a large insertion area. The tail cover of the board-end plastic body needs to reserve the board-end signal PIN insertion area and the board-end power PIN insertion area at the same time. 2) The line-end power PIN adopts the embedding method to achieve fixation in the line-end plastic body. The board-end power PIN also adopts the embedding method to achieve fixation in the board-end plastic body, which will seriously affect the heat dissipation performance of the line-end power PIN and the board-end power PIN. Furthermore, since the wire-end plastic body must be inserted into the cavity of the board-end plastic body, it means that part of the wire-end plastic body is circumferentially wrapped by the board-end plastic body. This results in a large amount of heat generated during the coordinated power transmission process between the wire-end power pin and the board-end power pin not being able to dissipate in time, and the operating temperature rises rapidly with continued use, which will inevitably affect the normal performance of the electrical connector assembly. 3) The design structure of wire-end and board-end electrical connectors is relatively complex, and the number of insertion holes to be formed on the wire-end and board-end plastic bodies is large, with a large area ratio. This places extremely high demands on the related injection molding process and molding quality. The above two factors lead to the high production cost of the electrical connector assembly. Therefore, it is urgent for technical personnel to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0047] The technical scheme disclosed by the utility model will be further explained in detail below in combination with specific embodiments, Figure 3 , Figure 4 The utility model discloses an electrical connector assembly, which comprises a wire end electrical connector 1 and a board end electrical connector 2. In specific application, the wire end electrical connector 1 and the board end electrical connector 2 work together to transmit signals or electrical energy.
[0048] As shown in Figure 5 , 6 The wire end electrical connector 1 mainly comprises a wire end plastic body 11, wire end signal PINs 12 and a wire end power supply PIN 13. The wire end signal PINs 12 are inserted into the wire end plastic body 11, and the wire end power supply PIN 13 is assembled on the wire end plastic body 11 and contacts the circumferential side wall of the wire end plastic body 11. Figure 10 , 12 The wire end power supply PIN 13 is a sheet metal bending piece, which is connected by a contact function segment 131 and a wire welding segment 132. When the wire end power supply PIN 13 is assembled on the wire end plastic body 11, the contact function segment 131 passes through the strip-shaped embedding notch 111 and is position-locked by force interaction with the circumferential side wall of the wire end plastic body 11, and the wire welding segment 132 is electrically connected to the wire harness by means of soldering. Figure 7 , 8 The wire end plastic body 11 is provided with a strip-shaped embedding notch 111 for inserting the wire end power supply PIN 13. Figure 11 The wire end power supply PIN 13 is a sheet metal bending piece, which is connected by a contact function segment 131 and a wire welding segment 132. When the wire end power supply PIN 13 is assembled on the wire end plastic body 11, the contact function segment 131 passes through the strip-shaped embedding notch 111 and is position-locked by force interaction with the circumferential side wall of the wire end plastic body 11, and the wire welding segment 132 is electrically connected to the wire harness by means of soldering.
[0049] As Figure 17 , 18 , shown in 19, the board end electrical connector 2 is mainly composed of a board end plastic body 21, a board end signal PIN 22, and a board end power PIN 23, and the like. The board end signal PIN 22 (as shown in 21) takes the tail cover plate of the board end plastic body 21 as the insertion and fixing base. The board end power PIN 23 takes the board end plastic body 21 as the assembly base. The number of the board end power PIN 23 is 2, and is symmetrically arranged on both sides of the cavity 211. As shown in 22, the board end power PIN 23 is a sheet metal bending piece, which is sequentially connected by a circuit board welding section 231, an embedded fixing section 232, and an electrical conduction section 233. As shown in 23, Figure 23 , Figure 24 , the embedded fixing section 232 is positionally locked due to the force interaction with the side wall of the cavity 211, and the electrical conduction section 233 is hidden in the cavity 211. Figure 18 , 21 , a embedding slot 214 is formed on the tail cover plate of the board end plastic body 21 to limit and fix the embedded fixing section 232. In the completed assembly state of the board end power PIN 23 relative to the board end plastic body 21, the embedded fixing section 232 is positionally locked due to the force interaction with the side wall of the cavity 211, and the electrical conduction section 233 is hidden in the cavity 211.
[0050] As shown in 27, Figure 25 , 26 , in the completed insertion state of the wire end electrical connector 1 relative to the board end electrical connector 2, the wire end signal PIN 12 can be in conduction with the board end signal PIN 22 to cooperatively transmit signals, and the electrical conduction section 233 applies an elastic pressing force to the wire end power PIN 13, and itself approaches / elastically presses the side wall of the cavity 211 due to the reaction force, so that the wire end power PIN 13 can be in conduction with the board end power PIN 23 to cooperatively transmit electrical energy.
[0051] In actual application, the electrical connector assembly disclosed by the utility model has at least the following beneficial technical effects, specifically:
[0052] 1) In the utility model, the traditional pin electrical conduction mode is abandoned, the wire end power PIN 13 and the board end power PIN 23 are both preferably stamping flat structures, and have a larger contact area after electrical conduction, so as to ensure that the electrical connector assembly can more stably transmit electrical energy in actual application, and has a more excellent large current carrying capacity; and also benefits from the stamping flat design structure of the wire end power PIN 13 and the board end power PIN 23, the manufacturing difficulty and cost are effectively reduced, and in addition, the board end power PIN 23 realizes electrical conduction with the wire end power PIN 13 in an elastic pressure contact mode, so that the board end power PIN 23 and the wire end power PIN 13 can still be in good conduction even in the case of high frequency high secondary excitation of the electrical connector assembly, further improving the stability and reliability of electrical energy transmission of the electrical connector assembly.
[0053] 2) When the wire end electrical connector 1 is assembled, the wire end power pin 13 is in contact with the circumferential side wall of the wire end plastic body 11, and part of it is exposed; when the board end electrical connector 2 is assembled, the electrically conductive section 233 of the board end power pin 23 is hidden in the cavity 211 and is adjacent to the side wall of the cavity 211. In this way, on the one hand, the heat generated during the electrical conduction process has the following three diffusion paths: direct diffusion to the outside through the exposed parts of the wire end power pin 13 and the board end power pin 23; diffusion to the outside through the insertion gap between the wire end electrical connector 1 and the board end electrical connector 2; diffusion to the wire end plastic body 11 and the board end plastic body 21 by heat conduction or radiation; the electrical connector assembly has good heat dissipation performance, avoiding the occurrence of the phenomenon that the subsequent working performance is affected by the high working temperature; on the other hand, under the premise that various design indicators are met, the design size of the wire end plastic body 11 and the board end plastic body 12 can be greatly reduced, which is beneficial to the overall design size of the electrical connector assembly.
[0054] It also needs to be emphasized here that the number of insertion holes required to be formed on the wire end plastic body 11 and the board end plastic body 21 is greatly reduced, which can to some extent relax the requirements for the related injection molding process and molding quality, and is beneficial to the further reduction of the molding cost of the electrical connector assembly.
[0055] As shown in Figure 11 , the wire welding section 132 presents a U-shaped groove shape, and a plurality of tin containing grooves 1321 are arranged in the wire welding section 132 along the linear distribution direction of the power wire bundle. In this way, after the soldering operation is completed, the connection strength and stability between the power wire bundle and the wire end power pin 13 are greatly enhanced, thereby effectively reducing the phenomenon that the power wire bundle is pulled off from the wire end power pin 13 due to the pulling force.
[0056] In order to ensure that the wire end power pin 13 has good firmness after being assembled with the wire end plastic body 11, and to avoid the occurrence of the phenomenon that the wire end power pin 13 is accidentally pulled off due to the pulling force, as a further optimization of the above technical solution, as shown in Figure 11 , the contact function section 131 is simultaneously formed with an extension hooking protrusion 1311 and an internal elastic resistance arm 1312. As shown in Figure 7 , 8 , the wire end plastic body 11 is formed with a resistance increasing notch 112 matched with the internal elastic resistance arm 1312. When the wire end power pin 13 is assembled with the wire end plastic body 11, the extension hooking protrusion 1311 penetrates into the circumferential side wall of the strip-shaped embedding notch 111, and the internal elastic resistance arm 1312 sinks into the resistance increasing notch 112 (as shown in Figure 14 , 15, 16 shown in the drawings.
[0057] As shown in Figure 5 , 7 , 8 shown in the drawings can also be clearly seen that the line end plastic body 11 is also shaped with a process sink 113, in order to place the contact function section 131, so that the total width value of the line end plastic body 11 remains unchanged, the open size of the two opposite line end power PIN13 is reduced to a certain extent, for the further reduction of the overall design of the electrical connector assembly.
[0058] Furthermore, as shown in Figure 11 , 14 , 15, the contact function section 131 is subjected to a beveling process to form a clearance bevel 1313. And the free end of the clearance bevel 1313 does not exceed the process sink 113 in the assembled state of the line end power PIN13 relative to the line end plastic body 11. So in the process of inserting and assembling the line end electrical connector 1 and the board end electrical connector 2, the board end power PIN23 can smoothly pass through the line end power PIN13, and finally be elastically pressed on the line end power PIN13.
[0059] Furthermore, as shown in Figure 24 , it can also be clearly seen that the electrical conduction section 233 is composed of a plurality of electrical conduction fingers 2331. And the adjacent electrical conduction fingers 2331 are cut by a strip-shaped cut 2332. So when the line end electrical connector 1 and the board end electrical connector 2 are inserted and assembled, each electrical conduction finger 2331 is elastically pressed on the line end power PIN13, and the pressing action is independent of each other, which is beneficial to realize large-area contact and good conduction (as shown in Figure 25 , 26 , 27).
[0060] In addition, as shown in Figure 18 , 21 , 22, it can also be clearly seen that the tail cover plate of the board end plastic body 21 is also shaped with a heat dissipation notch 215. In the actual application, the heat generated during the electrical conduction process of the line end power PIN13 and the board end power PIN23 can be dissipated through the heat dissipation notch 215 in the state of the line end electrical connector 1 and the board end electrical connector 2 being inserted and assembled, which further optimizes the heat dissipation performance of the electrical connector assembly.
[0061] In the practical application of the electrical connector assembly, the wire end electrical connector 1 is prone to misplug phenomenon (for example, the wire end electrical connector 1 is inserted into the board end electrical connector 2 with an error of 90° or 180° relative to the correct plug-in posture), which further causes the misplug relationship between the wire end electrical connector 1 and the board end electrical connector 2, and further causes the occurrence of product function failure or equipment damage phenomenon. In view of this, as a further optimization of the above technical solution, as shown in Figure 7 、 8 , 20, 26, 27, the circumferential side wall of the wire end plastic body 11 is simultaneously formed with the first anti-fumble groove 114 and the second anti-fumble groove 115, and correspondingly, the side wall of the cavity 211 is simultaneously formed with the first anti-fumble convex strip 212 matched with the first anti-fumble groove 114 and the second anti-fumble convex strip 213 matched with the second anti-fumble groove 115. The design shape and / or design size of the first anti-fumble groove 114 and the second anti-fumble groove 115 are different. In this way, even if the operator has a misoperation action, the wire end electrical connector 1 cannot be inserted into the board end connector 2, thereby effectively preventing the occurrence of the connector assembly misplug phenomenon, ensuring that the signal or electric energy can be correctly transmitted, and effectively avoiding the occurrence of product function failure or equipment damage phenomenon caused by the misplug relationship between the wire end electrical connector 1 and the board end electrical connector 2.
[0062] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
