Specific embodiment

The core of the utility model is to provide a kind of optical fiber connector, and intensity is high, non-deformability is strong, and installation side Just.

It should be noted that the herein presented noun of locality " upper and lower " refers to upper and lower in Fig. 2 to " interior " refers to It is the direction in Fig. 2 inside metal shell, " outer " refers to the direction outside metal shell in Fig. 2.

In order to which those skilled in the art is made to more fully understand the utility model, below in conjunction with the accompanying drawings and specifically The utility model is described in further detail for embodiment.

It please refers to Fig.2 and Fig. 3, Fig. 2 is the structure diagram of optical fiber connector provided by the utility model, Fig. 3 Fig. 2 In the first buckling parts the first specific embodiment structure diagram.

The utility model provides a kind of optical fiber connector, and including metal shell 1, the metal shell 1 is by brass or table copper etc. Material is made, and is circumferentially closed, the front and rear encirclement structure communicated, and during installation, metal shell 1 is set in socket 2 from front to back Outside, due to being respectively provided with claw at left and right sides of 1 lower end of metal shell, after metal shell 1 is connected with socket 2, by gold The claw for belonging to shell 1 is clamped to PCB backboards, is mounted and fixed to so as to fulfill by socket 2 on PCB backboards.The utility model Will in the prior art, the structure for the downwardly open semi-surrounding that metal shell 1 has is changed into full encirclement structure, is set in slotting During the outside of seat 2, by mounting means in the prior art from top to bottom, suit mode from front to back is changed into so that metal Intensity higher, the non-deformability of shell 1 are more preferable, significantly extend the service life of metal shell 1.

To further improve the non-deformability of metal shell 1, can first buckling parts be set in the bottom surface of metal shell 1 11, which is separable buckle type structure, and the mistake in 2 outside of socket is set in from front to back in metal shell 1 Cheng Zhong, the first buckling parts 11 are automatically separated, to reserve installation space, facilitate installation；After installing, the first buckling parts 11 is automatic It is closed；Due to the first buckling parts 11 suit during can automatic open-close, effectively reduce deformation therefore, effectively reduce The deformation intensity of metal shell 1.

First buckling parts 11 specifically includes the first left buckling parts 111 positioned at left end and the first right fastening positioned at right end Portion 112, other structures of the first left 111 and first right buckling parts 112 of buckling parts with metal shell 1 are integrally formed structure.

In the first specific embodiment, the first left buckling parts 111 is circular groove, the first right buckling parts 111 is round Shape protrusion, after metal shell 1 is set with 2 phase of socket, circular protrusions are fastened in circular groove, and to the first left buckling parts 111 and first right buckling parts 112 carry out punching press so that the two closely connects.Circular groove and bulge-structure can be reduced effectively Stress concentration, and it is easy to process；To cause connection more secured, which can be set multiple, Duo Ge One buckling parts 111 can be uniformly distributed along the extending direction of metal shell 1 or non-uniform Distribution, multiple first buckling parts 111 Between size can be equal, can not also wait, ensureing that the first left buckling parts 111 is fitted close with the first right buckling parts 112 is It can.

It please refers to Fig.4, Fig. 4 is the structure diagram of second of specific embodiment of the first buckling parts in Fig. 2.

In second of specific embodiment, the first left buckling parts 111 is square groove, and the first right buckling parts 112 is side Shape protrusion, square groove and bulge-structure, after may be such that punching press, the button of the first left 111 and first right buckling parts 112 of buckling parts Conjunction relation is more secured, and facilitates processing；To further improve connection relation, which can be set more A, multiple first buckling parts 11 can be uniformly distributed along the extending direction of metal shell 1 or non-uniform Distribution, and multiple first Size between buckling parts 11 can be equal, can not also wait, and ensures that the first left buckling parts 111 is passed through with the first right buckling parts 112 It is fitted close after punching press.

Fig. 5 is refer to, Fig. 5 is the structure diagram of the third specific embodiment of the first buckling parts in Fig. 2.

In the third specific embodiment, the first left buckling parts 111 is trapezoidal groove, and the first right buckling parts 112 is ladder Shape protrusion, trapezoidal groove and bulge-structure so that fastening relation is stronger simultaneously, can reduce stress concentration；It can equally incite somebody to action Trapezoidal first buckling parts 11 is multiple along the extending direction setting of metal shell 1, can be uniformly distributed between multiple first buckling parts 11, with Facilitate processing, it also can non-uniform Distribution according to actual needs；Size between multiple first buckling parts 11 can be equal, can also It differs, ensures to be fitted close after the first left 111 and first right buckling parts 112 of buckling parts is stamped.

It should be noted that combining structure of different shapes can also be used in above-mentioned multiple first buckling parts 11, for example, multiple First buckling parts 11 can be circular, square and trapezoidal independent assortment structure.

Further to improve the resistance to deformation intensity of metal shell 1, the upper top surface that can also have metal shell 1 sets second Buckling parts, second buckling parts is identical with the structure of above-mentioned first buckling parts 11, is respectively provided with the second left buckling parts and the second right button Conjunction portion, the second left buckling parts equally can be circular groove, square groove or trapezoidal groove structure, and the second right buckling parts similarly may be used For circular protrusions, square protruding or trapezoidal protrusion, to be engaged with the second left buckling parts；To strengthen the second left buckling parts and the Bonding strength between two right buckling parts can equally set multiple second buckling parts, so that the second left buckling parts and second right side The connection of buckling parts is more secured；Combining structure of different shapes can also be used in multiple second buckling parts, not reinflated herein.

At this point, metal shell 1 be with left and right two split structures for being engaged structure, when installing metal shell 1, The left and right sides of metal shell 1 from socket 2 is installed to the outside of socket 2, and socket 2 is surrounded and fixed, then through the stamping process By the first of the first buckling parts 11 the left 111 and first right 112 and second left buckling parts of buckling parts of buckling parts and the second right fastening Portion is interlocked, fixes, so, since metal shell 1 is not affected by the squeezing action power of socket 2 in installation process, deformation Degree further reduces, intensity also obtains larger raising.

It, can also be in the outer lower portion of the first buckling parts 11 and the to lock above-mentioned first buckling parts, 11 and second buckling parts The outer upper of two buckling parts set respectively the first lock and second latch, first lock and second lock be equipped with fixed block with And the binding block being interlocked with fixed block, fixed block and binding block are respectively mounted on the first left buckling parts 111, the second left buckling parts, And the first right buckling parts 112, the second right buckling parts, to realize the locking after fastening.

Optical fiber connector provided by the utility model is described in detail above.Specific case used herein The principle and embodiment of the utility model is set forth, the explanation of above example is only intended to help to understand this practicality New method and its core concept.It should be pointed out that for those skilled in the art, this reality is not being departed from On the premise of with new principle, can also to the utility model, some improvement and modification can also be carried out, these improvement and modification are also fallen into In the protection domain of the utility model claims.
