Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a cable connector and connector assembly. Background Art

[0002] Cable connectors are typically used when connecting cables. Cable connectors are divided into male and female connectors, which are mating and plugged together. Two mating cable connectors are connected and disconnected by plugging and unplugging. Cable connectors have mating ends that mate with the mating connector. Existing cable connectors include... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the connector includes a connector housing 2 and multiple connection modules. Multiple module mounting slots are arranged side-by-side on the connector housing. Each connection module is installed in a corresponding slot and secured to the connector housing by a pressure strip 3 spanning across the modules. Each connection module is connected to a cable 1, which is a high-speed cable containing two signal transmission lines for transmitting differential signals. The signal transmission lines are surrounded by a shielding layer. Each connection module includes a module housing 8, contacts 7, and a shielding structure. The contacts 7 are arranged in pairs to form differential pairs, each formed by a pair of pins. The cable passes through the module housing, and the signal transmission lines are electrically connected to the corresponding contacts. The shielding layer is electrically connected to the shielding structure. The insertion / removal direction of the cable connector is the first direction. The cable connector has a plug-in end in the first direction and a second direction and a third direction perpendicular to the first direction. The shielding structure includes a first-side shielding plate 4 and a second-side shielding plate 6 disposed on the module housing. The first-side shielding plate and the second-side shielding plate are opposite each other in the second direction. The contact is located between the first-side shielding plate and the second-side shielding plate. Shielding spacers 5 are also provided on both sides of the third direction of the contact. The two ends of the shielding spacers are connected to the first-side shielding plate and the second-side shielding plate, respectively. The shielding spacers separate the contacts of two adjacent connecting modules. The shielding spacers on both sides of the contact of each connecting module, together with the first-side shielding plate and the second-side shielding plate, form a mating cavity. The contact is located in the mating cavity for the adapter connector to be plugged in and connected.

[0003] However, when manufacturing this type of cable connector, the cable, contacts, and shielding components need to be assembled into individual modules first, and then each module is installed onto the connector housing. This requires that each module housing, first-side shielding plate, and second-side shielding plate be manufactured separately, resulting in a large number of parts, complex processing, and high manufacturing costs. Summary of the Invention

[0004] The purpose of this invention is to provide a cable connector to solve the problem of high manufacturing cost of existing cable connectors; the purpose of this invention is also to provide a connector assembly to solve the problem of high manufacturing cost of existing connector assemblies.

[0063] The present invention will be further described in detail below with reference to embodiments.

[0064] Embodiment 1 of the cable connector of the present invention:

[0065] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the cable connector includes a connector housing 2, a retaining strip 3, contacts 7, a shielding plate assembly, and a cable 1. The shielding plate assembly forms a shielding structure, including a first-side shielding plate 4, a second-side shielding plate 6, and shielding spacers 5. Multiple pairs of contacts 7 are provided along the left-right direction, each pair forming a differential pair. The contacts are formed by pins. The cable 1 is connected to each differential pair in a one-to-one correspondence. The retaining strip 3 is used to fix each cable 1 to the connector housing 2. The first-side shielding plate 4 covers the upper side of each contact 7, and the second-side shielding plate 6 covers the lower side of each contact 7. Shielding spacers 5 are located on both the left and right sides of the contact 7. The shielding spacers 5 cooperate with the first-side shielding plate 4 and the second-side shielding plate 6 to provide shielding around the contact 7.

[0066] The first direction of a cable connector is front-to-back, the second direction is up-and-down, and the third direction is left-to-right. The front end of the cable connector is the insertion end, and the insertion and removal direction is front-to-back. A pair of contacts constitutes one contact path, and the contacts in each path are arranged alternately on the left and right sides.

[0067] The connector housing 2 is divided into a front, middle and rear section along the front-to-back direction. The connector housing 2 and the contact 7 are fixed together by integral molding. The front part of the connector housing 2, which is used to fix the contact, constitutes the contact fixing part. The contact 7 is fixed to the front part of the connector housing, and the front end of the contact 7 extends forward out of the connector housing to connect with the adapter connector.

[0068] The connector housing 2 has a central mounting hole in the middle, which is vertically continuous and square. There are multiple central mounting holes, spaced apart along the left and right direction. Each central mounting hole corresponds to a differential pair. The rear end of the contact 7 extends rearward into the central mounting hole. The central mounting hole forms an operating opening, which is used to create a connection operating space between the cable 1 and the contact 7.

[0069] The connector housing 2 has a rear mounting groove at the rear. The rear mounting groove extends back and forth with its opening facing upward. There are multiple rear mounting grooves, which are arranged at intervals along the left and right direction. Each rear mounting groove corresponds to a cable 1. The rear mounting groove corresponds to and communicates with the central mounting hole. The rear mounting groove passes through the central mounting hole in the front and extends backward to the rear end face of the connector housing 2 to form a rearward opening. The cable 1 is installed in the rear mounting groove. The cable 1 has a connecting end for connecting to the contact 7. The connecting end extends into the central mounting hole. The rear end of the contact 7 is connected to the connecting end of the cable 1 in the central mounting hole.

[0070] Cable 1 includes two signal lines for transmitting differential signals and a shielding layer around the signal lines. The connection end of cable 1 is provided with a shielding ring 9. The shielding ring 9 is clamped around the shielding layer of cable 1 to make close contact with the shielding layer. Conductive adhesive 10 is applied between the shielding ring 9 and the shielding layer. The conductive adhesive 10 is applied between the rear end of the shielding ring 9 and the end face of the insulating outer sheath. The conductive adhesive 10 will penetrate into the gap between the shielding ring 9 and the shielding layer to ensure reliable shielding and conduction.

[0071] The signal line of cable 1 protrudes forward from the shielding ring 9. The two signal lines of cable 1 correspond one-to-one with the two contacts 7 of the differential pair and are soldered together. An epoxy resin fixing body 11 is poured at the solder joint to ensure reliable connection.

[0072] The rear part of the upper side of the connector housing 2 is provided with a relief groove. The groove opening faces upward and extends in the left and right direction. The relief groove intersects with the rear mounting groove. The pressure strip 3 is a long strip that extends in the left and right direction. The pressure strip 3 is inserted into the relief groove to sink into the connector housing and press the cable 1 from above downward. The pressure strip 3 is straddling above each cable 1 in the left and right direction. The pressure strip 3 is used to press and fix each cable 1 in the corresponding rear mounting groove.

[0073] The first side shield 4 is installed on the upper side of the connector housing 2, and the front end of the first side shield 4 protrudes from the connector housing 2. The first side shield 4 covers the upper side of each contact 7 in the left-right direction, and the first side shield 4 covers each central mounting hole. The first side shield 4 has clearance openings that correspond one-to-one with the central mounting holes so that the shielding ring 9 can be exposed. The first side shield 4 has a fixing protrusion 41, a crimping spring 42, and a first shielding connection hole 43. The fixing protrusion 41 protrudes downward. The connector housing 2 has a shielding fixing hole 21, which corresponds one-to-one with the fixing protrusion 41. The fixing protrusion 41 and the shielding fixing hole 21 are forcibly fitted together, and the fixing protrusion 41 is forcibly inserted into the shielding fixing hole 21 to fix the first side shield 4 to the connector housing 2. The crimping spring 42 is used to press against the shielding ring 9. The crimping spring 42 has a clearance opening, with crimping springs 42 on both the left and right sides of the clearance opening. The two crimping springs 42 extend relative to each other, protruding downwards from the lower side of the first side shielding plate 4, so that when the first side shielding plate 4 is fixed to the connector housing 2, it forms a pressing contact with the shielding ring 9 in the mounting hole. For reliable contact, the adjacent ends of the two crimping springs 42 at the same clearance opening are welded together. The first shielding connection holes 43 are spaced apart in the left-right direction and are used for fixing the shielding spacer 5.

[0074] The shielding spacer 5 extends in the front-to-back direction, with its rear end mounted on the connector housing 2 and its front end protruding from the connector housing 2. Multiple contact protrusions 51 are provided at both the upper and lower ends of the shielding spacer 5. Correspondingly, multiple first shielding connection holes 43 are provided. The first shielding connection holes 43 are adapted to the contact protrusions 51 at the upper end of the shielding spacer 5 so that the contact protrusions 51 at the upper end of the shielding spacer 5 can be inserted accordingly. The contact protrusions 51 protrude upwards from the first shielding connection holes 43. The first side shielding plate 4 and the shielding spacer 5 are fixedly connected at the contact protrusions 51 at the upper end of the shielding spacer 5 by laser welding. The connection is made by welding the opening edge of the first shielding connection hole 43 to the contact protrusions 51, ensuring reliable shielding. Contact springs 52 are also provided on the left and right sides of the shielding spacer 5. The contact springs 52 are located on the front side of the connector housing 2 and are used to make contact with the shielding components of the compatible connector.

[0075] The connector housing 2 is provided with a shielding fixing groove 24, which is vertically continuous and has an opening on the front end face of the connector housing 2. The shielding fixing groove 24 is adapted to the shielding spacer 5. The shielding spacer 5 is pressed into the shielding fixing groove 24 to fix it to the connector housing 2. The front end of the shielding spacer 5 extends forward out of the shielding fixing groove 24. The contact protrusions 51 at the upper and lower ends of the shielding spacer 5 protrude from the upper and lower sides of the groove opening of the shielding fixing groove 24, respectively. The shielding fixing groove 24 is provided with a side shielding support 25. The side shielding support is connected to the left and right sides of the groove wall of the shielding fixing groove 24, respectively. There are multiple side shielding supports 25, and each side shielding support is spaced apart so that the contact protrusions 51 at the lower end of the shielding spacer 5 can extend downward out of the shielding fixing groove 24.

[0076] like Figure 12 , Figure 13 , Figure 14 As shown, the second side shield 6 is installed on the lower side of the connector housing 2. The second side shield 6 covers the lower side of each contact 7 in the left-right direction, and also covers each mounting hole. Each contact 7 is located in the space between the first side shield 4 and the second side shield 6. The rear end of the second side shield 6 is fixed to the connector housing 2, and the front end protrudes forward from the connector housing 2. The second side shield 6 is provided with a heat-riveting fixing hole 61, a limiting hole 62, and a second shielding connection hole 63. The connector housing 2 is provided with a heat-riveting post 22, which passes through the heat-riveting fixing hole 61 to heat-rivet the second side shield 6 to the connector housing 2. The connector housing 2 is also provided with a limiting post 23, which corresponds to and cooperates with the limiting hole 62. Both the limiting post 23 and the limiting hole 62 are square, and the limiting post 23 is inserted into the limiting hole 62. The second shielding connection hole 63 is for the contact protrusion 51 at the lower end of the shielding plate 5 to be inserted. The second shielding connection hole 63 is provided in multiple places corresponding to the contact protrusion 51 at the lower end of the shielding plate 5.

[0077] Each shielding spacer 5 is spaced apart in the left-right direction. Every two adjacent shielding spacers 5, together with the first side shielding plate 4 and the second side shielding plate 6, form a mating cavity. The contact is located within the mating cavity, which is used for the insertion of the mating connector. The portions of the first side shielding plate, the second side shielding plate, the shielding spacers, and the contact protruding from the connector housing together form the mating end of the cable connector. Two adjacent mating cavities share one shielding spacer 5, and all mating cavities share the first side shielding plate 4 and the second side shielding plate 6.

[0078] This allows the cable 1 and the contact 7 to be directly mounted on the connector housing 2, relying on the connector housing for support, and using the operating port to connect the contact 7 to the cable 1. One connector housing 2 is used to connect each group of contact 7 to the cable 1. A first-side shielding plate 4 covers each contact 7 on the upper side, and a second-side shielding plate 6 covers each contact 7 on the lower side. This simplifies the installation and shielding structure, reduces the number of parts, facilitates processing, and saves manufacturing costs.
