Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to the field of high-speed integrated cable assembly technology, and particularly to a cable connector assembly with an outward-inward locking mechanism. Background Technology

[0002] In the prior art, patent publication number CN205429310U, patent title: An Electrical Connector Assembly, discloses an electrical connector assembly including a plug and a socket. The plug includes a circuit board, an insulating body, and a cable. The circuit board is horizontally placed and has a mating end and a connecting end facing each other. Metal contact pieces are arranged on the upper and lower surfaces of the mating end. The mating end protrudes forward from the insulating body, and the connecting end is fixed in the insulating body. The front end of the cable is electrically connected to the connecting end, and the rear end of the cable extends backward from the insulating body. The socket includes an insulating base, a plurality of conductive terminals housed in the insulating base, and a metal shell covering the insulating base. The insulating base has a slot. The conductive terminals have arc-shaped contact portions extending into the slot and solder feet extending out of the insulating base. The contact portions are arranged in two rows in the slot. The metal shell includes a top wall, a bottom wall, and two side walls covering the outside of the insulating base. The top wall, bottom wall, and side walls protrude forward from the insulating base. A plug hole is formed between the top wall, bottom wall, and side walls, located in front of the slot, and the two are interconnected.

[0003] The existing technology has the following drawbacks: In the existing technology, when the plug is inserted into the socket, the front end of the insulating body is inserted into the socket hole, and the mating end of the circuit board is inserted into the slot, so that the contact piece and the contact part make elastic contact to achieve electrical connection. However, when the space in the customer's institution is narrow and the plug size is made very short, due to the stress of the cable, the plug is more likely to be inserted at an angle when plugged in and out, which may cause the top of the circuit board to cross the contact part of the conductive terminal, resulting in the risk of pin collapse. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a cable connector assembly with an outward-inward locking mechanism, which reduces the risk of pin collapse.

[0006] In a preferred embodiment of the present invention, the conductive element is provided with a mating portion and a soldering portion at both ends; the mating portion can be connected to the matching end connector, and several cables are soldered to the soldering portion.

[0007] In a preferred embodiment of the present invention, a plurality of anti-foolproof structures are provided between the mating portion and the welding portion of the conductive element, and / or the conductive element is further provided with a limiting protrusion and / or a limiting groove embedded in the insulating body.

[0009] In a preferred embodiment of the present invention, at least one pair of forward-extending baffles are respectively provided on the outer side of one end of the main body where the interlocking portion is provided, and the baffles and the main body form a concave slot.

[0010] In a preferred embodiment of the present invention, a mounting base is provided on the main body, and the locking spring is provided on the mounting base, the locking spring being elastically locked on the mounting base; the mounting base includes at least a pair of sidewalls provided on the upper part of the main body, and a recessed locking cavity is formed between the oppositely arranged sidewalls; positioning holes are respectively provided on the inner side of the sidewalls, and a steering shaft is pivotally arranged in the oppositely arranged positioning holes, the steering shaft dividing the locking cavity into an elastic pressing area and a locking area.

[0011] In a preferred embodiment of the present invention, the locking spring includes an arc-shaped structure that is movably inserted between the steering shaft and the locking cavity. One side of the arc-shaped structure is connected to an elastic reset member disposed in the elastic pressing area via a guide portion, and the other side of the arc-shaped structure is connected to a limiting portion disposed in the locking area.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances. Example 1

[0031] like Figures 1-7As shown, a cable connector assembly with an outward-inward locking mechanism includes an insulating body 1 that mates with a mating connector 6. The insulating body 1 includes a main body 11. A pair of forward-extending baffles 102 are provided on the outer side of the end of the main body 11 that mates with the mating connector 6, forming a recessed slot 111 between the baffles 102 and the main body 11. The slot 111 between the baffles 102 and the main body forms an open U-shaped cavity, guiding and correcting the orientation of the mating connector 6 and the insulating body 1 during the mating process. The insulating body 1 also has a locking spring 4 that can correspondingly engage with the mating connector 6. A conductive element 2 is fixedly embedded within the main body 11; one end of the conductive element 2 mates with the mating connector 6, and the other end of the conductive element 2 is connected to several cables 3, electrically connecting the multiple cables 3 to the mating connector 6 through the conductive element 2.

[0032] Specifically, such as Figures 2-4 As shown, the conductive element 2 is a printed circuit board. The conductive element 2 has a mating portion 201 and a soldering portion 202 at both ends. The mating portion 201 can mate with the matching connector 6. Multiple cables 3 are arranged in two rows and soldered to the solder joints on the upper and lower surfaces of the soldering portion 202. One end of the cable 3 is soldered to the soldering portion 202 and embedded in the main body 11, while the other end of the cable 3 extends outside the main body 11. The mating portion 201 of the conductive element 2 extends to the outside of the other end of the main body 11. Several misaligned anti-foolproof structures 203 are also provided between the mating portion 201 and the soldering portion 202 of the conductive element 2. The anti-foolproof structure 203 uses an asymmetrical circular hole structure, but is not limited to this; other structures with anti-foolproof functions in the prior art can also be used. The conductive element 2 also has a limiting protrusion embedded in the main body 11, but is not limited to this; in other embodiments, a limiting groove structure can also be used as the limiting structure.

[0033] Specifically, such as Figures 1-7 As shown, a mounting base 10 is provided on the main body 11, and a locking spring 4 is provided on the mounting base 10. The locking spring 4 is elastically locked on the mounting base 10. The mounting base 10 includes at least a pair of side walls 104 provided on the upper part of the main body 11, and a recessed locking cavity is formed between the oppositely arranged side walls 104. The inner side of the side walls 104 is provided with symmetrical positioning holes 105 respectively, and a steering shaft 5 is pivotally arranged in the oppositely arranged positioning holes 105. The steering shaft 5 divides the locking cavity into an elastic pressing area and a locking area.

[0034] More specifically, the locking spring 4 is a metal locking spring. The locking spring 4 includes an arc-shaped structure 408 passing between the steering shaft 5 and the locking cavity. One side of the arc-shaped structure 408 is connected to the elastic reset member disposed in the elastic pressing area via a guide part 404, and the other side of the arc-shaped structure 408 is connected to the limiting part 405 disposed in the locking area; the arc-shaped structure 408 and the guide part 404 together form a V-shaped guide structure. The elastic reset member includes a fixing part 401 that mates with the elastic pressing area. A pressing part 403 is provided on the upper part of the fixing part 401, and the fixing part 401 is elastically connected to the pressing part 403 via an elastic part 402. Furthermore, the fixing part 401 and the pressing part 403 are plate-shaped structures, parallel to each other, and the pressing part 403 is parallel to the horizontal plane. The elastic part 402 adopts an arc-shaped spring structure. Furthermore, a limiting block 101 is provided within the elastic pressing area, and a limiting groove 406 is provided on the fixing part 401 to engage and limit the limiting block 101; a support arm 407 is also provided on the fixing part 401 to be embedded in the side wall 104. A limiting block is provided above the side of the limiting part 405 near the mating part 201; the limiting part 405 spans the locking area, and several downwardly protruding locking bosses 409 are provided below the limiting part 405, with the locking bosses 409 corresponding to the locking area. The locking bosses 409 can engage with the locking holes 601 on the mating connector 6, thereby achieving mating and interlocking between the locking spring 4 and the mating connector 6. Example 2

[0035] A method for fabricating a cable connector assembly with an outward-inward locking mechanism, such as... Figures 1-7 As shown, firstly, the printed circuit board of conductive element 2 is assembled. Both ends of conductive element 2 are respectively provided with interlocking and soldering portions. Cable 3 is soldered to the corresponding soldering portions to form a module. The outer conductive element 2 has a foolproof structure 203, i.e., an asymmetrical circular hole structure, on both sides. The insulating body 1 is an injection molded body, including a main body 11 and a pair of opposing baffles 102 disposed on both sides of the front end of the main body 11. During injection molding, the interlocking portion of conductive element 2 is exposed outside the main body 11 of the insulating body 1, while its soldering portion is enclosed inside the main body 11. The foolproof structure 203 of conductive element 2 serves for positioning and foolproofing during injection molding. One end of cable 3 is soldered to the soldering portion of conductive element 2, and the other end of cable 3 is led out of the insulating body 1.

[0036] The baffles 102 on both sides of the injection-molded insulating body 1 and the main body 11 cooperate to form a constraint with the two outer side walls 104 of the mating end connector. Each baffle 102 and the main body 11 have an anti-rotation rib 103 for correction and anti-rotation.

[0037] The upper part of the insulating body 1 is injection molded with a mounting base 10. The mounting base 10 includes two side walls 104 extending from the upper part of the main body 11. The inner side of the two side walls 104 is provided with guide grooves 106. The guide grooves 106 are used to accommodate and embed the support arms 407, so as to facilitate the constraint between the support arms 407 on both sides of the fixing area on the locking spring 4 and the guide grooves 106. At the same time, the insulating body 1 is provided with a limiting block 101 for docking and constraining the fixing part 401 and the limiting groove 406.

[0038] The method of use and working principle of this invention:

[0039] like Figures 1-7 As shown, the mating locking involves mating the mating connector 6 with one end of the insulating body 1 that has the mating portion 201. The cooperation between the baffles 102 on both sides of the insulating body 1 and the main body 11 forms a constraint with the two outer side walls 104 of the mating connector. The elastic part 402 of the locking spring 4 is provided with a locking boss 409 with a forward-inclined guide slope. When mating with the mating connector 6, the locking boss 409 extends from top to bottom into the locking hole 601 on the mating connector 6 to form an interlock.

[0040] like Figures 1-7 As shown, the separation and unlocking process is as follows: The steering shaft 5 is fixed in the positioning holes 105 inside the two side walls 104 of the insulating body 1, and the arc-shaped structure 408 on the locking spring 4 used to limit the metal contact. When the pressing part 403 is pressed down, the elastic part 402 deforms and pulls the guiding part 404 to rotate around the steering shaft 5 through the arc-shaped structure 408, causing the limiting part 405 to open outward. At the same time, the locking boss 409 disengages from the locking hole 601 of the mating end connector, completing the unlocking.

[0041] The above specific embodiments are specific support for the concept proposed in this invention, and should not be used to limit the scope of protection of this invention. Any equivalent changes or modifications made on the basis of this technical solution in accordance with the technical concept proposed in this invention shall still fall within the scope of protection of this invention.
