Description

Technical Field

[0001] The invention relates to a cable connector assembly, and in particular to a cable connector assembly for high-speed transmission. Background Art

[0002] Cable connector assemblies are widely used in data centers such as switches and servers. When the cable connector assembly is inserted into the board end cage, the triangular boss of the cable connector assembly needs to be hooked with the triangular groove in the board end cage, so as to achieve the function of insertion and locking without falling off. The pull strap is pulled to make the triangular boss of the cable assembly sink, so as to achieve the unlocking and pulling function with the triangular groove in the board end cage. The unlocking pull tabs of existing connectors have various unlocking structures, but they generally have problems such as large space occupation, poor strength, short service life, and unreliable unlocking. Summary of the invention

[0003] In order to solve the above technical problems, an object of the present invention is to provide a cable connector assembly with an unlocking structure that occupies a small space and has a long service life.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A cable connector assembly includes a first shell, a second shell, a circuit board, a locking member and a pull strip. The first shell and the second shell are fixed to each other, the circuit board is clamped between the first shell and the second shell, the locking member is hinged on the second shell, a clamping strip is extended from the lower part of the locking member to the board end, a spring is provided between the clamping strip and the second shell, both sides of the locking member extend upward and penetrate the second shell to form a pull strip, an unlocking block is provided at one end of the pull strip, a guide groove is provided on the first shell, the unlocking block is arranged in the guide groove, and the unlocking block drives the pull strip to rotate.

[0006] As a preferred solution: the unlocking block includes hook strips distributed on both sides and a crossbeam connecting the two hook strips, and the front end of the hook strip is folded inwards and buckled with the pull strip. The hook strips on both sides are connected by the crossbeam, which has higher overall strength, is not easy to deform, and is more stable to unlock.

[0007] As a preferred solution: a through hole is provided on the second shell for the pull bar to pass through, and a second limiting groove is also provided next to the through hole, a second limiting protrusion is provided on the lower side of the hook portion, and the second limiting protrusion is located in the second limiting groove.

[0008] As a preferred solution: a first limiting groove is provided on the first housing, a first limiting convex block is provided on the upper side of the hook portion, and the first limiting convex block is located in the first limiting groove. Through the cooperation between the convex block and the limiting groove, when the lock buckle reaches the unlocking position, the unlocking block can be limited to prevent excessive pulling, which causes the hook portion and the pull bar to bear too much force and cause loosening.

[0009] As a preferred solution: the lock piece is hinged to the second housing through an axis, and the spring between the locking strip of the lock piece and the second housing is a conical spring. The conical spring is low in height when compressed, which can reduce the space on the second housing to accommodate the lock piece, thereby making the unlocking structure occupy less space as a whole.

[0010] As a preferred solution: a mesh tail component is further provided at one end of the first shell and the second shell, and the mesh tail component is fixed on the cable. The mesh tail component is fixed to the cable, which can not only realize the positioning of the cable, facilitate operations such as stripping and welding, but also prevent the cable from being loosened from the circuit board when the cable is pulled.

[0011] As a preferred solution: an inner mold is provided between the first shell and the second shell, a notch is provided at the bottom of the inner mold, a convex strip is provided on the second shell, and the convex strip is clamped in the notch. The inner mold also adopts a limit structure to improve the cable's anti-pulling ability.

[0012] As a preferred solution: the first shell and the second shell are both made of aluminum alloy, and the first shell and the second shell are fixed by rivets.

[0013] As a preferred solution: the first shell and the second shell are also wrapped with electromagnetic interference shrapnel at the parts close to the cable end.

[0014] As a preferred solution: the pull strap is made of plastic, the unlocking block is made of metal, and the pull strap and the unlocking block are integrally formed.

[0015] The present invention arranges the unlocking block on the pull belt, and a guide groove is provided on the shell. The unlocking block moves along the guide groove. The unlocking block is restricted by the first shell and the second shell and is not easy to loosen, thereby reducing the risk of unlocking failure. The unlocking block is distributed along both sides of the shell, and the space inside the shell is smaller, which is convenient for the arrangement of cables of more specifications. In addition, the pull belt and the unlocking block are integrally formed, and the structure is reasonable and the strength is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1 to 7 The cable connector assembly shown includes a first housing 1, a second housing 2, a circuit board 12, a locking member 7 and a drawstring 3. The first housing 1 and the second housing 2 are fixed to each other, the circuit board 12 is sandwiched between the first housing 1 and the second housing 2, the locking member 7 is hinged to the second housing 2 through an axis 6, a clamping strip is provided at the lower part of the locking member 7 extending toward the board end, a spring 10 is provided between the clamping strip and the second housing 2, both sides of the locking member 7 extend upward and penetrate the second housing 2 to form a drawstring, an unlocking block 4 is provided at one end of the drawstring 3, a guide groove is provided on the first housing 1, the unlocking block 4 is arranged in the guide groove, and the unlocking block 4 drives the drawstring to rotate. The drawstring 3 is made of plastic, the unlocking block 4 is made of metal, and the drawstring 3 and the unlocking block 4 are integrally formed.

[0025] The unlocking block 4 includes hook strips distributed on both sides and a crossbeam connecting the two hook strips, the front end of the hook strips is folded inwards and buckled with the pull strip. The hook strips on both sides are connected by the crossbeam, the overall strength is higher, it is not easy to deform, and the unlocking is more stable.

[0026] The second shell is provided with a through hole 22 for the pull bar to pass through, and a second limiting groove 23 is also provided next to the through hole 22. A second limiting convex block is provided at the lower side of the hook bar portion, and the second limiting convex block is located in the second limiting groove 23. The first shell is provided with a first limiting groove 101, and a first limiting convex block is provided at the upper side of the hook bar portion, and the first limiting convex block is located in the first limiting groove 101. Through the cooperation between the convex block and the limiting groove, when the lock reaches the unlocking position, the unlocking block can be limited to prevent excessive pulling, so that the hook bar portion and the pull bar are subjected to excessive force, resulting in loosening.

[0027] The lock member 7 is hinged on the second housing 2 through the shaft 6, and the spring between the locking strip of the lock member 7 and the second housing 2 is a conical spring. The conical spring has a lower height when compressed, which can reduce the space on the second housing to accommodate the lock member, thereby making the unlocking structure occupy less space as a whole.

[0028] A net tail component 8 is also sandwiched at one end of the first shell 1 and the second shell 2, and the net tail component 8 is fixed on the cable 11. The net tail component is fixed to the cable, which can not only realize the positioning of the cable, facilitate operations such as stripping and welding, but also prevent the cable from being loosened from the circuit board when the cable is pulled. An inner mold 5 is also provided between the first shell 1 and the second shell 2, and a notch 51 is provided at the bottom of the inner mold 5. A convex strip 21 is provided on the second shell 2, and the convex strip 21 is clamped in the notch 51. The inner mold also adopts a limiting structure to improve the cable's anti-pulling ability.

[0029] The first shell 1 and the second shell 2 are both made of aluminum alloy, and the first shell 1 and the second shell 2 are fixed by rivets. The first shell 1 and the second shell 2 are also wrapped with electromagnetic interference shrapnel 9 near the cable end.

[0030] The working principle of the present invention is as follows: by pulling the drawstring backward, the backward force is transmitted to the unlocking piece at the front end of the drawstring, and the hook strips on both sides of the unlocking key respectively drive the pull strips on both sides of the lock fastener, so that the lock fastener rotates under the action of the shaft, and the triangular boss at the front end of the lock fastener sinks. When it is completely sunk into the plane of the zinc alloy shell, the active unhooking and unlocking function is realized. After unlocking, the lock fastener is automatically reset by the rebound force of the spring. Since the unlocking piece moves as a whole in the guide groove of the shell, compared with the unlocking piece being directly exposed outside the shell, the unlocking piece is not easy to fall out of the shell, and the risk of unlocking failure is lower.

[0031] It should be noted that the above embodiments are only representative examples of the present invention. The present invention can also have many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the essence of the present invention should be considered to belong to the protection scope of the present invention.
