Description

Outer conductor structure

Cross Reference to Related Applications

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

Technical Field

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

Background

Known connectors having open and closed inlets are, for example, "PosiBand" connectors produced by Positronic (Positronic).

Fig. 3 shows a connector with an open inlet. Such connectors have an interface side front edge that is not circumferentially closed. The discontinuity of the leading edge is usually formed by a contact lug. Connectors with open access 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 entry prevent the connector from being damaged by mechanical forces, such as by attempting to engage an improperly mated connector, and also result in a much higher mating force.

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

The outer conductor 90 of a High Voltage (HV) connector designed for frequencies in the megahertz range is shown in fig. 5. The outer conductor comprises a closed entrance 91 and a spring-loaded contact lug 92 with a contact point 93, the contact point 93 being located behind the closed entrance. The outer conductor resonates according to a change in frequency, which is affected by the capacitance between the engaging members. Although the above disadvantages are not yet apparent in this frequency range, there is still a need to manufacture outer conductors suitable for connectors in higher frequency ranges.

This situation needs to be improved.

Disclosure of Invention

Some embodiments of the present invention are directed to a connector having a closed inlet and improved impedance characteristics.

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

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

The idea underlying some embodiments of the invention is to arrange the ends of the contact lugs of the outer conductor behind the outer conductor ring so that the contact lugs are flexibly deformable to ensure a low engagement force, while the closed inlet will be created by the outer conductor ring.

The contact lugs which are not fixed to the outer conductor ring therefore 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 in 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 combination described in each case, but also in other combinations or alone, without departing from the scope of the invention.

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

According to some embodiments of the invention, the outer conductor ring is designed to protect the contact lugs from mechanical forces. This is necessary if the connectors can also be engaged from an oblique direction, or in the engaged state, are subjected to the influence of a force from an oblique direction without damaging the outer conductor. According to one embodiment of the invention, such protection of the contact lugs can be ensured by a closed entry of the outer conductor.

Accordingly, some embodiments of the present invention address the problem of increasing the stability of the connector while reducing the engagement force. However, in practice, the optimization 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, the at least one contact lug is formed as a holding lug, to which the outer conductor ring is connected. The outer conductor ring can thus be mounted particularly easily and securely on the outer conductor base body.

Alternatively, the outer conductor ring may be mounted on another portion of the outer conductor. In particular, the retention 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 a spring-loaded characteristic if they are only fixed on the outer conductor base body. This makes it possible to form the holding lug so that the rigidity of the holding lug is greater than the rigidity of the loose contact lug.

If the outer conductor ring is fixed on a plurality of lugs, in particular on two lugs on the outer conductor base body, the lugs have a lower spring performance than contact lugs which are not fixed on the outer conductor ring.

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

According to some embodiments of the invention, the outer conductor structure has a diameter jump between the outer conductor base body and the outer conductor ring. 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 involving diameter jumps.

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

According to some embodiments of the invention, the outer conductor ring is connected to the outer conductor base body by a connection method, for example by soldering. Alternatively, the outer conductor ring and the outer conductor base body may be made of an adhesive.

According to some selected embodiments of the invention, the outer conductor base has two retention lugs. The retention lugs may be linear or curved.

In this case, it is further advantageous to provide spring-loaded contact lugs in the holding lugs.

According to some embodiments, the outer conductor ring has a protective collar which projects in the 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 body against damage by mechanical forces. In this case, a protective collar may be provided to prevent the contact lugs from being damaged by the 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 lug covering the front end of the contact lug.

According to some embodiments, the contact lugs each have a raised contact point for establishing contact with the mating connector. Thus, the contact lugs are prestressed in the engaged state, so that the contact and therefore the protection of the connector are improved. In order to reduce the engagement force, these 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 stamped parts can be produced in a particularly economical manner. In particular, the production of stampings can be highly automated. However, for connectors with closed entrances, a jump in diameter is only possible in the stamping process in association with other mechanical disadvantages (for example high engagement forces or low contact forces).

The above-described 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 which are not explicitly mentioned above 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 present invention.

Detailed Description

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

The outer conductor base body 200 comprises a plurality of contact lugs 201 on its upper and lower side and corresponding retaining lugs formed as contact lugs 203 on the right and left side. Contact lug 203 is slightly larger than contact lug 201 and therefore also harder than contact lug 201. The outer conductor ring 300 is also formed on the contact lug 203 as one body, which contributes more to increase the rigidity of the contact lug 203 than the contact lug 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 conductor of the mating plug connector which is engaged with the outer conductor arrangement 100. This ensures electromagnetic shielding of the upper and lower sides of the outer conductor structure 100 for the inner conductors (not shown) which are guided through in the outer conductor base body 200.

In fig. 2, the contact lugs 203 also each have a contact point 205. The contact point 205 is arranged 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 body 200 is provided with 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. Alternatively, the outer conductor base 200 and the outer conductor ring 300 may be formed as one piece.

The outer conductor ring 300 includes a protective collar 305 that protects the ends of the contact lugs 201 from forces caused by foreign objects.
