Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication transmission, and in particular, to a high-speed electrical connector.

Background Art

[0002] Electrical connector assemblies allow users of electronic devices or external devices to transfer data to other devices and devices or communicate with other devices and devices. Generally, the electrical connector assembly includes a pluggable module received within a receptacle assembly, and the receptacle assembly includes a receptacle connector removably coupled to the pluggable module. The receptacle assembly includes a metal cage having an internal compartment therein for receiving the pluggable module. The receptacle connector is held within the internal compartment of the cage for connection to the pluggable module when the pluggable module is inserted therein, such as SFP, QSFP, and the like.

[0003] Such receptacle connectors in the prior art generally include an insulating base, a plurality of terminals incorporated within the insulating base, an insulating housing sleeved around the periphery of the insulating base, and a metal cage covering the outside of the insulating housing. An insertion cavity is formed at the front end of the insulating housing, and each terminal forms a cantilever-like contact section protruding into the insertion cavity for docking with a docking module. The contact sections are arranged in two upper and lower rows in the left-right direction, and the upper row of contact sections and the lower row of contact sections are generally arranged in a staggered manner in the left-right direction (that is, they do not correspond in the up-down direction. In other words, the upper row of contact sections and the lower row of contact sections are not mirror-symmetrical in the up-down direction). Therefore, when forming the contact sections, it is often achieved by bending or twisting a metal sheet, so that the extending path of a completed terminal is not in a plane. When such a terminal configuration is assembled into the insulating housing by insertion, it is necessary to make way for the bent contact sections. Thus, the contact sections have a great possibility of displacement in the arrangement direction (left-right direction), which is not conducive to the overall stability of the receptacle connector and the docking stability with the docking module. Moreover, the relatively long cantilever-like contact sections are also prone to deformation, resulting in misalignment during docking with the docking module, and thus causing defects.

[0004] Therefore, it is necessary to design an improved connector to solve the above technical problems.

Summary of the Invention

[0005] The purpose of the present application is to provide a new high-speed electrical connector with better structural stability.

[0006] To achieve the above purpose, the present application is realized through the following technical solutions:

The terminal module includes a support body and a plurality of terminals combined with the support body. The front end of the insulating housing forms a docking cavity for cooperating with the docking module and forms an insertion port. The rear end of the insulating housing forms an installation cavity, and the installation cavity communicates with the docking cavity. Each of the terminals includes a contact section protruding into the docking cavity, and the contact sections are arranged in at least one row at the inner side position of the docking cavity. It further includes a limiting member. The insulating housing is formed with a limiting hole penetrating along the arrangement direction of the contact sections and the insertion and extraction direction of the docking module. The limiting hole corresponds to the docking cavity, and the limiting member is correspondingly inserted into the limiting hole and is located between at least two adjacent contact sections.

[0008] Furthermore, the limiting member includes a plurality of grid portions arranged at intervals and a main body portion integrally connecting the plurality of grid portions. Each of the grid portions is correspondingly limited between two adjacent contact sections.

[0010] Furthermore, along the arrangement direction of the contact sections and the insertion and extraction direction of the docking module, the barrier beam corresponds to the contact section one by one.

[0011] Furthermore, each of the terminals includes a fixed section combined in the support body, the contact section extending from one end of the fixed section out of the support body and protruding into the docking cavity, and a docking section extending from the other end of the fixed section out of the support body for contacting the mating circuit board. The contact section extends in a non-linear shape along the insertion and extraction direction of the docking module.

[0012] Furthermore, the contact section includes a base section integrally connected to the fixed section, a bending section connected to the end of the base section away from the fixed section, and a connection section connected to the end of the bending section away from the base section. The connection section is used for electrically contacting the docking module, and both the base section and the connection section extend along the insertion and extraction direction of the docking module.

[0013] Furthermore, along the arrangement direction of the contact sections, the limiting member corresponds to the base section.

[0014] Furthermore, the insulating housing extends a partition wall into the docking cavity at a position near the insertion port on the inner wall of the docking cavity. Along the arrangement direction of the contact sections, adjacent two connection sections are separated by the partition wall.

[0015] Further, several of the terminals include several signal terminals and several ground terminals. The several signal terminals and several ground terminals are arranged at intervals according to a specific rule. The terminal module is inserted into the installation cavity along the extraction direction of the docking module. The support body is formed by stacking and combining several terminal substrates along the arrangement direction of the contact section, and each terminal substrate incorporates a signal terminal or a ground terminal.

[0016] Further, the docking cavity defines opposite upper inner wall surfaces and lower inner wall surfaces. Among them, the upper inner wall surface is provided with a row of upper front row contact sections near the insertion port position and a row of upper rear row contact sections away from the insertion port position. The lower inner wall surface is provided with a row of lower front row contact sections near the insertion port position and a row of lower rear row contact sections away from the insertion port position. The limiting member correspondingly cooperates with a row of upper front row contact sections and / or a row of lower front row contact sections.

[0034] This application will be described in detail below with reference to the drawings and in conjunction with the embodiments. For the convenience of description, the upper, lower, left, right, front and rear orientations in this application are relative positions and do not constitute a limitation on implementation.

[0035] Please refer to Figures 1 to 13As shown, a high-speed electrical connector disclosed in the present application is used for electrical connection to a mating circuit board (not shown). The high-speed electrical connector includes a connector module 10 and a metal cover 20 covering the periphery of the connector module 10. The connector module 10 includes a terminal module 1 and an insulating housing 2. The terminal module 1 includes a support body 11 and a plurality of terminals 12 combined with the support body 11. A mating cavity 201 for cooperating with a mating module (not shown) is formed at the front end of the insulating housing 2, and an insertion opening 200 is formed. An installation cavity (not labeled) is formed at the rear end of the insulating housing 2, and the installation cavity communicates with the mating cavity 201. The terminal module 1 is inserted and assembled into the installation cavity along the extraction direction of the mating module and is fixed to the insulating housing 2.

[0036] Each of the terminals 12 includes a contact section 1201 protruding into the mating cavity 201. The contact sections 1201 are arranged in at least one row at the inner side surface position of the mating cavity 201. Specifically, in the present application, the mating cavity 201 defines opposite upper inner wall surfaces 2011 and lower inner wall surfaces 2012 (as shown in the reference). Figure 4 As shown, the upper inner wall surface 2011 is provided with a row of upper front row contact sections 12001 near the insertion opening 200 and a row of upper rear row contact sections 12002 far from the insertion opening 200, and the lower inner wall surface 2012 is provided with a row of lower front row contact sections 12003 near the insertion opening 200 and a row of lower rear row contact sections 12004 far from the insertion opening 200 (please refer to the figures). Figure 8 and Figure 7 and Figure 4 shown).

[0037] In the high-speed electrical connector disclosed in the present application, a row of upper front row contact sections 12001 and a row of lower front row contact sections 12003 correspond in the up-down direction, and each contact section 1201 in a row of upper front row contact sections 12001 is arranged in a staggered manner with each contact section 1201 in a row of lower front row contact sections 12003 in the arrangement direction (i.e., the left-right direction). The high-speed electrical connector disclosed in the present application can be an SFP, QSFP socket electrical connector or others.

[0038] Please refer to Figure 3 and 4 and Figures 6 to 13As shown, the high-speed electrical connector of the present application further includes a limiting member 3. The insulating housing 2 is formed with a limiting hole 203 penetrating along the arrangement direction of the contact segments 1201 perpendicular to the contact segments 1201 and the insertion and extraction direction of the docking module. The limiting hole 203 corresponds to the docking cavity 201, and the limiting member 3 is correspondingly inserted into the limiting hole 203 and limited between the adjacent contact segments 1201. The limiting member 3 is used to limit excessive displacement movement (specifically referring to the arrangement direction of the contact segments 1201) between the adjacent contact segments 1201. Specifically, in the present application, the limiting member 3 correspondingly cooperates with a row of upper front contact segments 12001 and / or a row of lower front contact segments 12003 (specifically in conjunction with the attached Figure 4 and 6 , 7, 8, 12, 13 shown). Taking the upper front contact segments 12001 and the upper rear contact segments 12002 as an example, due to the positional relationship between them, in the present application, the limiting member 3 is only used to cooperate with the upper front contact segments 12001. The upper rear contact segments 12002 cannot or are not preferably limited by the limiting member 3 inserted in the up and down direction due to the positional relationship.

[0039] Please refer to Figure 4 and Figures 6 to 11 shown, the limiting member 3 includes a plurality of grid portions 31 arranged at intervals and a main body portion 32 integrally connecting the plurality of grid portions 31. Each grid portion 31 is correspondingly limited between two adjacent contact segments 1201. The number of the limiting holes 203 corresponds to the grid portions 31. Adjacent two limiting holes 203 are separated by a barrier beam 204. The main body portion 32 is carried on the outside of the barrier beam 204, and each barrier beam 204 is located between two adjacent grid portions 31. Along the arrangement direction of the contact segments 1201 perpendicular to the contact segments 1201 and the insertion and extraction direction of the docking module, the barrier beam 204 corresponds to the contact segments 1201 one by one (refer to Figure 7 and 9 , 10, 11).

[0040] Please refer to Figure 7 and in conjunction with Figure 4 shown, each terminal 12 includes a fixed segment 1202 combined in the support body 11, a contact segment 1201 extending from one end of the fixed segment 1202 out of the support body 11 and protruding into the docking cavity 201, and a docking segment 1203 extending from the other end of the fixed segment 1202 out of the support body 11 for contacting the docking circuit board. The contact segment 1201 extends in a non-linear shape along the insertion and extraction direction of the docking module (in conjunction with Figure 7 and Figure 12 and Figure 13As shown. The contact section 1201 includes a base section 12011 integrally connected to the fixed section 1202, a bent section 12012 connected to one end of the base section 12011 away from the fixed section 1202, and a connection section 12013 connected to one end of the bent section 12012 away from the base section 12011. The connection section 12013 is used for electrical contact with the docking module. Both the base section 12011 and the connection section 12013 extend along the insertion and extraction direction of the docking module. Along the arrangement direction of the contact section 1201, the limiting member 3 corresponds to the base section 12011.

[0041] Further, an anti-interference wall 205 extends into the docking cavity 201 from the inner wall of the docking cavity 201 of the insulating housing 2 near the insertion port 200. Along the arrangement direction of the contact section 1201, adjacent two connection sections 12013 are separated by the anti-interference wall 205.

[0042] By providing the limiting member 3 in this application, the long contact section 1201 can be limited at the position of the base section 12011, preventing the contact section 1201 of the terminal 12 from being excessively deflected and displaced (mainly along the arrangement direction) during the docking of the high-speed electrical connector with the docking module, thus avoiding malfunctions. The assembly of the limiting member 3 in this application is convenient and the limiting effect is good.

[0043] Further, several terminals 12 in the high-speed electrical connector of this application include several signal terminals 121 and several ground terminals 122. The several signal terminals 121 and several ground terminals 122 are arranged at intervals according to a specific rule (in this application, the specific rule of interval arrangement means that two signal terminals 121 are arranged between adjacent two ground terminals 122). The terminal module 1 is inserted into the installation cavity along the extraction direction of the docking module. The support body 11 is formed by stacking and combining several terminal substrates 111 along the arrangement direction of the contact section 1201. Each terminal substrate 111 incorporates a signal terminal 121 or a ground terminal 122.

Although this application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of this application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of this application.
