Description

Outer conductor structure

Cross Reference to Related Applications

The application is a divisional application of a Chinese application patent application with the name of an external conductor structure, wherein the application date is 2019, 3, 12 and the application number is 201910184188.2.

Technical Field

The present application relates to an outer conductor structure and a method for producing an outer conductor structure.

Background

Known connectors having an open inlet and a closed inlet are, for example, "PosiBand" connectors manufactured by baozi electronics limited (Positronic).

Fig. 3 shows a connector with an open inlet. Such connectors have an interface-side leading edge that is not circumferentially closed. The interruption of the leading edge is typically formed by a contact ledge. Connectors with open access can better compensate for manufacturing tolerances and reduce the engagement force required for engagement purposes.

Fig. 4 shows a connector with a closed inlet. Such connectors have a closed interface side front edge. The contact lugs may be surrounded by a housing. Connectors with closed access openings prevent the connector from being damaged by mechanical forces, such as by attempting to engage an improperly engaged connector, and also result in a significantly higher mating force.

Attempts in the prior art have shown that the optimization of one of the parameters EMC tightness, engagement force, stability, etc. of the connector in the high frequency range is contradictory to the impedance optimization. This can be seen in the existing products of the applicant rosenberg (Rosenberger Hoch-frequenztechnik GmbH & co.kg), for example. Fig. 5 shows such a product.

An outer conductor 90 designed for use with High Voltage (HV) connectors for megahertz range frequencies is shown in fig. 5. The outer conductor comprises a closed inlet 91 and a spring-loaded contact lug 92 with a contact point 93, the contact point 93 being located behind the closed inlet. The outer conductor resonates according to the frequency change, under the influence of the capacitance between the engagement members. Although the above drawbacks are not yet apparent in this frequency range, there is still a need to manufacture an outer conductor suitable for connectors in a higher frequency range.

This situation needs improvement.

Disclosure of Invention

Some embodiments of the invention aim to provide a connector with a closed inlet and improved impedance characteristics.

According to some embodiments of the present invention, there is provided an outer conductor structure for a connector, having an outer conductor base and an outer conductor ring; wherein the outer conductor base has a plurality of contact lugs; wherein the outer conductor ring adjoins an interface-side end of the outer conductor base body, the outer conductor ring being fixed to the outer conductor base body by means of a holding lug in at least one fastening region, and the outer conductor ring having a closed structure to form a closed inlet of the outer conductor structure; wherein contact lugs are provided which are not fastened to the outer conductor loop.

In some embodiments, a diameter jump is formed between the outer conductor loop and the outer conductor base. In some embodiments, the diameter of the outer conductor base is greater than the diameter of the outer conductor loop.

The idea underlying an embodiment of the invention is that the end of the contact lug of the outer conductor is arranged behind the outer conductor ring such that the contact lug can be flexibly deformed to ensure a low engagement force, while at the same time a closed inlet is created by the outer conductor ring.

Thus, the contact lugs that are not fixed to the outer conductor ring have the same tolerance compensating properties as the contact lugs according to fig. 3.

In some embodiments of the present patent application, a ring is understood to be a circumferential object, the cross-section of which may alternatively be circular, oval, elliptical, etc.

Advantageous configurations and further developments are disclosed in the further dependent claims and the description with reference to the figures.

It goes without saying that the features mentioned above and those yet to be explained below can be applied not only in the combinations described in each case, but also in other combinations or alone, without departing from the scope of the invention.

In some embodiments, it may be provided in particular that the outer conductor ring has no projections or recesses.

According to some embodiments of the invention, the outer conductor loop is designed to protect the contact lugs from mechanical forces. This is necessary if the connector can also be engaged from an oblique direction or in an engaged state receive the influence of a force from the oblique direction without damaging the outer conductor. According to one embodiment of the invention, this protection of the contact lugs may be ensured by the closed access of the outer conductor.

Thus, some embodiments of the present invention address the problem of reducing the engagement force while increasing the stability of the connector. However, in practice, the optimisation of these two properties is contradictory, and the desire to enhance stability results in an undesirable increase in the engagement force and vice versa.

According to some embodiments of the invention, at least one contact lug is formed as a holding lug to which the outer conductor loop is connected. Thus, the outer conductor ring can be mounted particularly easily and firmly on the outer conductor base body.

Or the outer conductor loop may be mounted on another portion of the outer conductor. In particular, the holding lugs do not necessarily have to be contact lugs. The contact lugs are used to establish contact with a mating connector to which a connector having an outer conductor structure is to be connected.

The contact lugs have spring-loaded properties if they are only fixed to the outer conductor base. The holding lugs can thus be formed such that the stiffness of the holding lugs is greater than the stiffness of the loose contact lugs.

If the outer conductor loop is fixed to a plurality of lugs, in particular to two lugs which are fixed to the outer conductor base, the lugs have a lower spring property than contact lugs which are not fixed to the outer conductor loop.

It is advantageous if the main extension direction of the holding lugs extends in the circumferential direction of the outer conductor holding ring and/or if the main extension direction of the holding lugs is perpendicular to the main extension direction of the contact lugs.

According to some embodiments of the invention, there is a diameter jump between the outer conductor base of the outer conductor structure and the outer conductor loop. The jump in the diameter of the outer conductor enables the impedance to be adjusted. The connector according to the invention is particularly advantageous in that it can also be manufactured by a stamping method comprising diameter jumps.

If the connector according to some embodiments of the invention is manufactured by a stamping method, the diameter of the holding lugs may jump.

According to some embodiments of the invention, the outer conductor loop is connected to the outer conductor base by a connection method, for example by welding. Or the outer conductor loop and the outer conductor base may be made of an adhesive.

According to a part of an alternative embodiment of the invention, the outer conductor base has two holding lugs. The retention lugs may be linear or curved.

In this case, it is further advantageous if a spring-loaded contact lug is provided in the holding lug.

According to some embodiments, the outer conductor ring has a protective collar protruding in a radial direction with respect to the free end of the contact lug, wherein the protective collar is designed to protect the contact lug of the outer conductor base from damage due to mechanical forces. In this case, a protective collar may be provided to prevent the contact lugs from being damaged by an inserted object (e.g., a tool). In one embodiment, the protective collar may be formed as a vertical wall protruding from the outer conductor ring, or as a curved ledge covering the front end of the contact ledge.

According to some embodiments, the contact lugs each have a raised contact point for establishing contact with the mating connector. The contact lugs are thus prestressed in the engaged state, so that the contact is improved, and thus the protection of the connector is improved. In order to reduce the engagement force, the contact points may be arranged such that they are offset in the axial direction.

According to some embodiments, the outer conductor ring and the outer conductor base are formed as one piece.

According to some embodiments of the invention, the outer conductor base is formed as a stamping. The stamping can be produced in a particularly economical manner. In particular, the production of stamping parts can be highly automated. However, for connectors with a closed inlet, diameter jumps may only occur in the stamping process in association with other mechanical disadvantages, such as high engagement forces or low contact forces.

The above configurations and further developments can advantageously be combined with each other as desired. Other possible configurations, further developments and embodiments of the invention also include combinations of features of the invention not explicitly mentioned in the description hereinabove or in the following description with reference to the exemplary embodiments. In particular, in such a case, those skilled in the art will add various aspects as improvements or modifications to the respective basic forms of the invention.

Detailed Description

Fig. 1 shows a schematic view of an outer conductor structure 100 according to some embodiments of the invention in a non-assembled state. The outer conductor structure 100 according to some embodiments of the present invention includes an outer conductor base 200 and an outer conductor ring 300. The outer conductor structure 100 is for receiving one or more inner conductors and one or more insulator sections to provide a coaxial, twinaxial, or triaxial connector.

The outer conductor base 200 comprises a plurality of contact lugs 201 on its upper and lower sides and corresponding holding lugs formed as contact lugs 203 on the right and left sides. The contact lugs 203 are slightly larger than the contact lugs 201 and therefore also harder than the contact lugs 201. The outer conductor ring 300 is also formed integrally on the contact lugs 203, which is more helpful in increasing the rigidity of the contact lugs 203 relative to the contact lugs 201.

Each of the contact lugs 201 has a contact point 204 in the front end region. The contact points are formed as raised portions on the contact lugs 201 and, in the engaged state, establish contact with the outer conductors of the mating plug connector that is engaged with the outer conductor structure 100. This ensures electromagnetic shielding of the upper and lower sides of the outer conductor structure 100 of the inner conductor (not shown) which is guided through within the outer conductor base 200.

In fig. 2, the contact lugs 203 also each have a contact point 205. The contact point 205 is provided on a spring lug 207 in the contact lug 203. Thus ensuring that the outer conductor structure 100 also provides electromagnetic shielding at the sides of the outer conductor structure.

As can be seen from fig. 1, the outer conductor base 200 provides a diameter jump between the contact lugs 201, 203 and the outer conductor ring 300.

In fig. 1, the outer conductor ring 300 is connected to the outer conductor base 200 by a weld 209. Or the outer conductor base 200 and the outer conductor ring 300 may be formed as one piece.

The outer conductor ring 300 comprises a protective collar 305 protecting the ends of the contact lugs 201 from forces caused by foreign bodies.
