Description

Signal modules and electrical connectors Technical Field

[0001] This utility model belongs to the field of electrical connectors, and specifically relates to a signal module of an electrical connector and an electrical connector. Background Technology

[0002] After the signal module of the existing electrical connector is installed into the main plastic shell, the fixing structure to prevent the assembly parts of the two products from separating and falling off during movement is complex, and the mold implementation structure is also complex, resulting in high mold opening costs.

[0003] Existing electrical connectors have gaps when the signal inserts are inserted into the signal housing. When the connector is wrapped with adhesive at the tail, adhesive overflows from the gap in the signal module into the product, causing excessive mating force. In severe cases, the overflowing adhesive renders the connector unusable. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model designs a signal module of an electrical connector that is anti-reverse insertion and can be fixed, as well as an electrical connector having the signal module.

[0005] The technical solution of this utility model is as follows:

[0006] The signal module of the electrical connector includes a module body, characterized in that: a first guide groove and a second guide groove are provided on the surface of the module body, and the first guide groove and the second guide groove are not on the same surface of the module body, and the dimensional parameters of the first guide groove and the second guide groove are different.

[0007] The dimensional parameters of the first guide groove and the second guide groove include the width and depth of the groove, and at least one of the dimensional parameters of the first guide groove and the second guide groove is different.

[0008] Furthermore, a locking boss is provided in the first guide groove or the second guide groove. The locking boss is used to fix the position of the signal module on the electrical connector, so as to ensure that the signal module will not separate or fall off during the assembly and movement of the electrical connector.

[0009] Furthermore, it also includes a guide ramp, which is located in the first guide groove or the second guide groove. The guide ramp reduces the assembly difficulty of the locking boss and the electrical connector housing, making assembly easier.

[0010] Furthermore, the module body is provided with a number of mounting holes, including receiving holes and retaining holes.

[0011] Furthermore, it also includes a signal insert disposed in the mounting hole. The signal insert includes a conductive connection part, a transition part that mates with the retaining hole, and a wiring part that is connected to the transition part and located on the outside of the module body. Here, the structure of the module body is defined. The conductive connection part of the signal insert is embedded in the receiving hole of the module body. The connection between the signal insert and the module body is achieved through the mating of the transition part and the retaining hole.

[0012] Furthermore, an anti-overflow membrane is provided at the connection between the retaining hole and the receiving hole, and the thickness of the anti-overflow membrane is 0.2mm. During the assembly process of the signal plug and the module body, the wiring part and transition part of the signal plug puncture the anti-overflow membrane. After puncturing, the anti-overflow membrane adheres tightly to the surface of the transition part of the signal plug. When the tail of the electrical connector is wrapped with glue, it can effectively prevent glue from entering the receiving hole and ensure the reliability of the electrical connection of the signal module.

[0013] Furthermore, the wiring section is provided with a barbed protrusion near the transition section. When the signal plug is installed with the module body, the surface of the barbed protrusion abuts against the surface of the module body at the outer end of the retaining hole. The barbed protrusion plays a role in axial fixation, preventing the signal plug from falling off the module body.

[0014] Electrical connectors, including the signal modules of the aforementioned electrical connectors.

[0015] In summary, this utility model has the following beneficial effects:

[0016] This invention improves the signal module, which is installed from the front end of the main housing of the electrical connector and assembled in the mounting cavity of the main housing. The guide grooves on both sides of the signal module cooperate with the card plate to avoid reverse insertion, thereby preventing installation errors and ensuring product quality.

[0017] Furthermore, the cooperation between the second mounting plate and the locking boss enables the signal module to be fixed in the mounting cavity. After being fixed, the signal module cannot be removed from the mounting cavity. When the electrical connector with the signal module installed is circulating on the production line, the signal module will not fall off, thus avoiding product defects caused by the loss of parts during the production process.

[0018] Furthermore, the anti-overflow membrane is designed so that the signal inserts can pass through it during assembly. The anti-overflow membrane ensures a relative seal between the signal inserts, preventing glue from overflowing into the receiving hole when the connector is wrapped with adhesive, thus preventing product quality problems caused by glue overflow.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] In this invention, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0032] Figure 1 is a perspective view of an electrical connector according to an embodiment of this application; and Figure 2 is a perspective view of an electrical connector according to an embodiment of this application, wherein no signal module is installed in Figure 2.

[0033] The electrical connector includes a main housing 4. The front end of the main housing 4 is provided with a mounting cavity 40 for mounting a signal module. The signal module 5 is inserted from the front end of the main housing and fits into the mounting cavity 40. The signal module is provided with a first guide groove and a second guide groove. The inner wall of the mounting cavity is provided with a first locking platform 41 and a second locking platform 42. The locking platform can only mate with the corresponding guide groove. For example, the first guide groove can only mate with the first locking platform, and the second guide groove can only mate with the second locking platform. Therefore, the reverse insertion prevention function is realized when the signal module is assembled with the main housing.

[0034] Figure 3 is a perspective view of the signal module of an embodiment of this application; the signal module of the electrical connector in the figure includes a module body 1, which is generally square. A first guide groove 10 and a second guide groove 11 are provided on the surface of the module body 1. The first guide groove 10 and the second guide groove 11 are not on the same surface of the module body 1, and the size parameters of the first guide groove 10 and the second guide groove 11 are different. Specifically, in this embodiment, the first guide groove 10 is provided on one side of the module body 1, and the second guide groove 11 is provided on the opposite side. The first guide groove and the second guide groove are disposed on the opposite surfaces of the module body, and the size parameters of the first guide groove and the second guide groove are different.

[0035] Alternatively, a first guide groove 10 is provided on one surface of the module body, and a second guide groove 11 is provided on the surface of the module body adjacent to this surface. The guide grooves are not located at the center line of their respective surfaces. The anti-reverse insertion function is achieved by setting the first guide groove and the second guide groove in different positions.

[0036] The dimensional parameters of the first guide groove and the second guide groove include the width and depth of the groove. At least one of the dimensional parameters of the first guide groove and the second guide groove is different. The difference in dimensional parameters means that the width or depth of the first guide groove and the second guide groove are different in one or more ways. The mounting groove of the housing of the electrical connector is provided with a corresponding locking platform. The first guide groove and the second guide groove can only cooperate with the corresponding locking platform, thereby playing a role in preventing reverse insertion.

[0037] Specifically, this application has the following situations:

[0038] In the first case, the widths of the first guide groove 10 and the second guide groove 11 are different and their depths are also different. Here, the width and depth are modified. Only when the card plate on the module body matches the width and depth can it cooperate with the corresponding guide groove. At this time, it has a better anti-reverse insertion effect.

[0039] In the second case, the first guide groove 10 and the second guide groove 11 have the same width but different depths. In this case, the width of the first guide groove and the second guide groove are the same, so they cannot play a role in preventing reverse insertion. However, due to the different depths, when a signal module is inserted in reverse, the different depths of the grooves block the insertion of the signal module, thus playing a role in preventing reverse insertion.

[0040] The third type is where the widths of the first guide groove 10 and the second guide groove 11 are different but the depths are the same. In this case, the depths of the first guide groove and the second guide groove are the same, so they cannot play a role in preventing reverse insertion. However, due to the difference in width, when a signal module is inserted in reverse, the difference in width blocks the insertion of the signal module, thus playing a role in preventing reverse insertion.

[0041] Furthermore, referring to Figure 3, a locking boss 12 is provided in the first guide groove 10 or the second guide groove 11. The locking boss 12 is used to fix the position of the signal module on the electrical connector, ensuring that the signal module will not separate or fall off during the assembly and movement of the electrical connector. In one embodiment of this application, the locking boss is set in the second guide groove, and the end face of the locking boss is flush with the surface of the module body. A second locking platform 42 is provided on the inner wall of the mounting cavity of the main housing 4 corresponding to the second guide groove. The second locking platform is a triangular boss. During the assembly process of the module body and the mounting cavity, the second locking platform abuts against the surface of the locking boss. At this time, the module body is locked in the mounting cavity of the main housing. Without external force, the module body cannot be dislodged from the mounting cavity, thereby ensuring that the signal module will not separate from the main housing during the assembly and movement of the electrical connector.

[0042] Furthermore, it also includes a guide ramp 120, which is located in the first guide groove or the second guide groove. In one embodiment of this application, the guide ramp is located in the second guide groove. The guide ramp plays a guiding role, reducing the assembly difficulty of the locking boss and the electrical connector housing, and making assembly easier.

[0043] Referring to Figure 5, the module body 1 is provided with several mounting holes 2 and signal inserts 3 disposed in the mounting holes 2. The mounting holes 2 include receiving holes 20 and retaining holes 21. The signal insert 3 includes a conductive connection part 30, a transition part 31 that cooperates with the retaining hole, and a wiring part 32 that is connected to the transition part and located on the outside of the module body. The receiving cavity is provided to receive the conductive connection part of the signal insert, and the entire conductive connection part is located in the receiving cavity. The transition part of the signal insert is inserted into the retaining hole, which is used to fix and position the signal insert. The signal insert is a conductive component made of metal material. The conductive connection part includes a set of symmetrically arranged conductive arms, and a plugging space is formed between the two conductive arms. The signal pin on the other half of the electrical connector cooperates in the plugging space and connects to the two conductive arms. The wiring part is used to connect to the wires of other components.

[0044] Furthermore, an anti-overflow membrane 200 is provided at the connection between the retaining hole 21 and the receiving hole 20, and the thickness of the anti-overflow membrane is 0.2mm. During the assembly process of the signal plug and the module body, the wiring part and the transition part of the signal plug puncture the anti-overflow membrane. After puncturing, the anti-overflow membrane adheres tightly to the surface of the transition part of the signal plug. When the tail of the electrical connector is wrapped with glue, it can effectively prevent glue from entering the receiving hole and ensure the reliability of the electrical connection of the signal module.

[0045] Furthermore, the wiring portion 32 is provided with a barbed protrusion 320 near the transition portion. When the signal plug is installed with the module body, the surface of the barbed protrusion abuts against the surface of the module body at the outer end of the retaining hole. The barbed protrusion plays an axial fixing role, preventing the signal plug from falling off the module body.

[0046] In summary, this utility model has the following beneficial effects:

[0047] This invention improves the signal module, which is installed from the front end of the main housing of the electrical connector and assembled in the mounting cavity of the main housing. The guide grooves on both sides of the signal module cooperate with the card plate to avoid reverse insertion, thereby preventing installation errors and ensuring product quality.

[0048] Furthermore, the cooperation between the second mounting plate and the locking boss enables the signal module to be fixed in the mounting cavity. After being fixed, the signal module cannot be removed from the mounting cavity. When the electrical connector with the signal module installed is circulating on the production line, the signal module will not fall off, thus avoiding product defects caused by the loss of parts during the production process.

[0049] Furthermore, the anti-overflow membrane is designed so that the signal inserts can pass through it during assembly. The anti-overflow membrane ensures a relative seal between the signal inserts, preventing glue from overflowing into the receiving hole when the connector is wrapped with adhesive, thus preventing product quality problems caused by glue overflow.

[0050] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
