Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to connectors, and in particular to connectors that are stocked as semi-finished connector components, and which are later assembled with built-in electric elements such as filter elements, conductive spring pieces, etc.
By simply inserting the contacts that electrically connect these into the designated passages of the connector housing, you can configure a custom-made product for the user, and as a built-in electrical element, you can control the elimination of electromagnetic interference, high frequency interference, and radio interference. The present invention relates to a connector that employs elements and can be arranged according to user specifications.

[Prior Art] Conventionally, electromagnetic interference, high frequency and wireless radio signals have affected delicate electrical equipment and interfered with the functions of the equipment. Sources of electromagnetic interference include sparks, lighting, etc. , radar, television transmission signals, brush motors and line transients, but especially sparks from electrostatic discharges are often the cause of electromagnetic interference. It was inducing undesirable voltage signals into the equipment. Such interference is particularly common in electrical connection equipment, and can range from something as simple as a car radio to something as complex as an aircraft's navigation system.
It was causing the malfunction. Furthermore, in sensitive medical diagnostic equipment, misdiagnosis has even occurred due to electromagnetic interference or radio frequency interference. Therefore, the mitigation or elimination of electromagnetic or radio frequency interference in various types of electrical installations is of critical importance, and the environmental conditions and use There was a strong demand for excellent filter performance that could withstand the conditions. Also here,
There is a need for user-use connectors that can be adapted to a variety of interfaces for connecting different electrical devices to each other with minimal interference. This means that connector manufacturers keep semi-finished connectors in stock, and then, according to the user's instructions, filter connectors suitable for special applications in a variety of electrical devices are manufactured with the required number of contacts and the necessary filter elements in the semi-finished products in stock. There was a need for a system that could be manufactured quickly and easily simply by combining the two.

[0003] When we look at filter connectors related to the prior art, they are classified into the following four types. 1st
This type employs a monolithic flat plate capacitor in which each contact is connected in the axial direction.For example, U.S. Pat. Nos. 4,376,992 and 4,589,72
No. 0, No. 4,653,838, No. 4,710
, No. 710.

The second type comprises axial contacts and corresponding openings for connecting the contacts, with a capacitor mounted around each opening;
A contact passed through this capacitor in the axial direction. In other words, contacts are effectively electrically connected using a cylindrical sleeve capacitor.
, No. 710,285, No. 3,764,943,
Same No. 4,020,430, Same No. 4,215,326
No. 4,222,626, No. 4,256,
No. 506, No. 4,296,389, No. 4,6
There were No. 79,013 and No. 4,846,732.

A third type uses chip capacitors coupled to contacts, such as those disclosed in US Pat. Nos. 4,500,159 and 4,804,332.
No. 4,880,397.

The fourth type is called an array capacitor type in which a flat filter is connected to an axial contact.

[0007] However, there are many points that need to be improved in the known filter connectors. For example, the first type of monolithic flat plate filter is difficult to use in applications such as automobiles and airplanes due to the delicate structure of the filter itself. In harsh operating environments, embedded electrical components were susceptible to extreme temperatures and vibrations, rendering them useless. Second
Feed-through filter type filters using cylindrical capacitors have the problem of causing distortion and deformation due to vibration and applied pressure, and the capacitor itself is brittle and easily damaged. Like the type, there were limitations in its use. Those using the fourth type of array capacitor are expensive and difficult to manufacture, and have limitations in use due to the delicate structure of the filter itself. Furthermore, each type of filter connector had to be individually soldered or glued to the conductive plate, increasing assembly costs.

[0008] For the above reasons, the present invention provides the third
It uses built-in electrical elements such as chip-type or integrated filter connectors, but chip-type ones are cheaper than other types and have a tough structure. Of the third type, the above-mentioned U.S. Pat. No. 4,500,159 related to the present invention
No. 4,804,332, a series of cavities are arranged transversely above the axis of the contact, and an embedded electrical element, such as a chip capacitor or other chip electrical element, is inserted into each cavity from above. The capacitor was placed in direct and perpendicular contact with the mating contact, establishing a direct connection between the capacitor and the contact, for example.

However, in the third type, because of this direct connection relationship, if the contact is roughly inserted into the cavity, the capacitor etc. may be damaged and the torsional or rotational force may be applied. is transmitted directly from the contact to the capacitor, etc.
This has resulted in damage to the electrodes of the capacitor or the like, or a deterioration or complete failure of the electrical connection between the capacitor and the contacts.

Furthermore, the chip capacitor of the known technology is
In order for the connector to be finally assembled and function as a connector, it had to be securely fixed inside the connector. Therefore, in conventional technology, the connector components were manufactured as semi-finished products and then the user's It was not possible to configure the final product by inserting built-in electrical elements according to design specifications. For example, U.S. Patent No. 4,500
, No. 159, all chip capacitors were assembled into a row of cavities in a busbar, with individual capacitors placed in each cavity and directly connected to contacts with pins, sockets, etc. and the integrated spring member has a plurality of elastic teeth, each having a portion disposed inside the cavity to hold the chip capacitor in electrical connection with the contact;
An integral spring member pressed all chip capacitors into direct relationship with the contacts. Further, the integrated spring member not only maintains the electrical connection between the chip capacitor and the contact, but also has the function of grounding the chip capacitor.

However, this US Pat. No. 4,500
In No. 159, prior to the final product of the connector,
Each chip capacitor must be placed in its own cavity, which limits the connector to a few predetermined shapes, allowing users to customize the embedded electrical elements to suit each user's design specifications. This would completely eliminate the possibility of locating it.

[0012] Also in US Pat. No. 4,804,332, a bus bar is provided with a row of cavities for storing chip elements, each cavity is arranged to cross the axial direction of the contact, and a conductive member is connected to the contact. and had to be connected individually with each capacitor or chip electrical element. Additionally, each capacitor is preferably soldered or otherwise fixedly adhered to each cavity, resulting in a lack of flexibility in connector construction. That is, the capacitors had to be placed in a row on the busbar, and all rows of capacitors had to be inserted into the busbar at the same time and soldered, welded, or otherwise fixedly glued into the cavities. Therefore, it has been difficult to realize a flexible manufacturing method that allows each connector to be customized or configured based on a user's unique design. This is because, in the known technology, capacitors and the like are fixed in a predetermined arrangement inside the connector components prior to the final product of the connector, so it is not necessary to rearrange them later according to the actual requirements of the user. It was impossible.

[0013]

These are significant shortcomings in the prior art, which force users, such as computer manufacturers, to use inappropriate connector components for available connectors. This was an uneconomical process, as they had to force changes to their own design specifications, and also resulted in connectors that did not fully meet the user's design specifications that the system required. In some cases, connectors were unable to perform the filter function that they were supposed to perform. Also,
Traditional connectors require long waiting times for users because they have to be manufactured to the user's instructions before the product can be assembled or configured, and these delays mean that if the connector is If it were to become an element of the final product, it would completely disrupt users' schedules. Additionally, to meet user needs, connector manufacturers must produce and stock filter connectors that meet a wide variety of configurations and different design requirements, thus eliminating the problem of long wait times. Although this could be done, it would create problems such as huge inventories and a huge amount of frozen capital.

The prior art has also made the mistake of underestimating the connection distance between the filter means, such as a capacitor, and the contacts and earth, and overestimates the perfect earth connection due to the area connections to the contacts and filter means. Because I made the mistake of doing this, I increased the probability of stray inductance,
Many prior art filter connectors have been made poorly compatible with delicate electrical equipment.

The problem to be solved by the present invention is that the built-in electrical elements such as filter elements are fixed inside the connector and cannot be freely rearranged, which are the problems of the conventional art.
Solving the problem of underestimating the connection distance between the filter means and contacts and earth, and overestimating the complete grounding by area connection for the contacts and filter means,
The objective is to provide a connector with a versatile and simple structure.

[0016]

The goal of completing a connector that can be arranged according to user specifications was achieved without increasing inventory costs by using a versatile and simple connector structure.

[0017]

Embodiment 1 In FIG. 1, a connector 1 according to a first embodiment of the present invention includes a front insulator 10 and a rear insulator 20 as insulators forming a socket housing of the connector 1.

and. The plurality of second passages 22 penetrating the rear insulator 20 are provided parallel to and corresponding to the first passages 21 of the rear insulator, and the space between the first passages 21 and the second passages 22 is the same as that of the rear insulator. A communication port 21a is provided which is open by about half of the length of the communication port 20. The second passage 22 has an opening 22a extending to the side surface of the first passage 21 by penetrating the inside of the rear insulator 20 toward the outside.
The storage end 22b corresponding to the contact protrusion 32 of No. 0 (Figs. 2 and 4)

The number of digits such as 0 is different.

The ground plate 30 is provided across the insulator, that is, between the front insulator 10 and the rear insulator 20, and is provided in the first passages 11, 21 of the front insulator 10 and the rear insulator 20. A plurality of corresponding contact openings 31 (see the insertion line indicated by the dashed-dotted line) and a contact protrusion 32 corresponding to the second passage 22 of the rear insulator 20 (see the arrangement line indicated by the dashed-double line). and a connecting tab 33,
It is equipped with 33.

The conductive shields 40, 40, 41, 41 are
A pair of front conductive shields 40, 4 covering the front insulator 10
0, covering the rear insulator 20 and connecting tabs 33, 3
3 and a pair of rear conductive shields 41, 41 connected to the ground plate 30 by suitable connection means 400, which will be described later, and are grounded via the ground plate 30 (not shown).

A plurality of contacts 50 are prepared to be inserted into the first passages 11 and 21 of the front insulator 10 and the rear insulator 20 according to the number of poles of the connector 1 or user specifications. Although only one is shown in FIG. 1, a round front part 50a and a square rear part 50, respectively.
b, and the round front portion 50a is the ground plate 30.
It becomes a parallel receiving blade type socket that is inserted into the first passage 11 of the front insulator 10 through the contact opening 31 (see the insertion line shown by the dashed-dotted line), and the square rear part 50b is inserted as shown in the figure. Elastic rectangular protrusions 51, 51 cut rearward and raised forward and elastic rectangular protrusions 52, 52 cut forward are formed on the upper and lower surfaces of the first passage 21, as described below. It is formed to mesh with steps 211 and 212.

The conductive spring piece 60 is inserted into the second passage 22 into which the built-in electric element 70 is inserted, improves the electrical connectivity with the contact 50, and prevents the torsional force from the contact 50 from interfering with the contact 50. It has a transmission prevention structure that prevents transmission from being transmitted to the combined built-in electric elements 70, and this transmission prevention structure includes a rear flat plate surface of each pair of two plates extending outward from a common base 60a. 61, 61 and front flat plate surfaces 62, 63,
The front flat plate surfaces 62 and 63 are oriented to cross the rear flat plate surfaces 61 and 61, which form substantially parallel surfaces, along a horizontal axis passing through the center of the base 60a.

The built-in electric element 70 is selectively inserted into the opening 22a of the second passage 22, and a chip capacitor or other chip resistor as a chip filter element is selected according to the user's design specifications. can.

1-4, the front insulator 10, rear insulator 20, and ground plate 30 are combined to form the insert arrangement 1a, and the conductive shields 40, 4
1 and fixed with suitable connecting means 400, a connector component 1b as a semi-finished product according to the present invention is formed. The connecting means 400 includes, for example, a localization tab 401 provided on the front conductive shield 40.
After that, the conductive shield 41 is oriented, and the bolts 402 and nuts 403 are attached to the mounting holes 404 and 405 (see FIGS. 1 and 2) to complete the connector component 1b as a semi-finished product. Therefore, a built-in electrical element 70 specified by the user, such as a chip capacitor 70, etc., is inserted into the connector component 1b into the second passage 22 of the rear insulator 20, and then the conductive spring piece 60 is inserted into the connecting port 21a. When inserted until it hits the front joint plate portion 21b, the front electrode surface 71 of the built-in electric element 70 reaches the storage end 22b of the second passage 22 and comes into contact with the contact protrusion 32 of the ground plate 30. Then, when the conductive spring piece 60 is further pushed in, the rear end of the rear flat plate surfaces 61, 61 is moved to the step 221 of the second passage 22.
The front flat plate surface 62 engages with the built-in electrical element 70.
Since the rear electrode surface 72 of the ground plate 30 is pressed,
, good electrical connectivity is established between the conductive spring piece 60 and the built-in electrical element 70. At this time, the front flat plate surface 62 of the conductive spring piece 60 enters the first passage 21 through the communication port 21a, so that electrical connection with the contact 50, which will be described below, is possible.

Next, the insertion of the contact 50 into the connector component 1b will be explained. As can be easily understood from FIG. 3, two pairs of steps 211 and 212 are provided inside the rear insulator 20, corresponding to the elastic rectangular projections 51 and 52, respectively, in order to position the contact 50 in the correct position. Since the angle of cut and raise of the elastic rectangular protrusion 52 is made slightly narrower than the width of the first passage 21, the contact 50 can be easily inserted into the first passage 21, and
Just by inserting the contact 50, the contact 50 is positioned at the correct position and can be effectively prevented from moving back and forth. At this time, as is easy to understand when looking at FIG. 2, the square rear portion 50b of the contact 50 comes into contact with the front flat plate surface 63 that has entered the first passage 21 to establish an electrical connection.

The flange 12 is an insulator that is integrally molded on the rear end surface of the front insulator 10, as is easy to understand when looking at FIGS. so that the contacts 50 are completely surrounded by the front insulator 10 and the back insulator 20 and the contacts 50 are directly aligned with the ground plate 30.
prevent contact with In other words, the contact 50 is connected to the ground plate 30 only through the conductive spring piece 60 and the built-in electric element 70, suppressing the formation of stray inductance between the ground plate 30 and the contact 50, and preventing floating high frequency Insulating sealing can be achieved that substantially eliminates the diffusion of signals and the like.

The conductive spring piece 60, due to its unique resilient structure, allows the embedded electrical element 70 to enter the second passageway 22 of the connector without the need for welding, soldering, or other bonding. The ability to attach freely allows for easy configuration of flexible manufacturing systems that can be deployed by users. Furthermore, the transmission prevention structure of the conductive spring piece 60 can prevent transmission of torsional force or rotational force between the contact 50 and the built-in element 70. That is, as shown in FIGS. 1, 2, and 4, the built-in electric element 70 is parallel to the assembled contacts 50, and the front flat plate surface 6 has the elasticity of the conductive spring piece 60.
2 contacts the built-in electric element 70, and the front flat plate surface 63 also contacts the contact 50, thereby effectively preventing rotational force from being transmitted from the contact 50 to the built-in electric element 70.

The conductive spring piece 60 may have two approximately U
It can also be seen that the ridges are cross-connected to each other at a common base 60a. In other words,
The horizontally extended front flat plate surface 63 of the first U-shaped protrusion is provided to the adjacent parallel surface of the contact 50, and the other front flat plate surface 62 of the first U-shaped protrusion is provided to the front flat plate surface 63. The embedded electrical element 7 is oriented obliquely across the
It is provided to be elastically curved with respect to the electrode surface 72 of 0. The parallel rear plate surfaces 61, 61 of the second U-shaped protrusion are
Since it is expanded to the two opposing inner wall surfaces of the second passage 22 and positioned at the steps 221 1 and 221 2 , it has the effect of stabilizing the conductive spring piece 60 against the rotational force of the contact 50 . In other words, the built-in electric element 70 is connected to the conductive spring piece 6
Since the electrode surface 72 is in elastic and non-adhesive contact with the front flat surface 62 of the contact 50, no torsional or rotational force is transmitted from the contact 50 to the built-in electrical element 70. In this way, the contact 50 and the built-in electric element 70 are connected in a non-fixed manner, and the built-in electric element 70 is delicate due to the axial acting force of the contact 50.
, for example, to prevent damage to the chip capacitor 70 or to prevent incorrect handling of the embedded electrical element 70 , so that the electrical connection between the grounding plate 30 , the contact 50 and the embedded electrical element 70 is ensured by a conductive spring. With the strip 60, the axial force or torsional stress exerted on the integrated electrical element 70 by the axial force of the contact 50 is completely eliminated.

In FIGS. 2 and 4, the front joint plate portion 21b of the rear insulator 20 is tightly joined to the flange 12 of the front insulator 10, so that the dielectric side of the built-in electric element 70 is completely insulated. , electrode surfaces 71 and 72 of the built-in electric element 70
Only the ground plate 30 and the conductive piece 60 contact the contact 50 . Therefore, stray capacitance or leakage current that may be formed between the side surface of the embedded electrical element 70 and the ground plate 30 or the contact 50 can be suppressed, thereby improving the performance of the embedded electrical element 70, such as the chip capacitor 70. can be improved.

The functions of the present invention will be explained with reference to FIGS. 1 to 4.
By orienting the ground plate 30 across the first passages 11, 21 and the second passage 22 into which the connector housing is inserted, and connecting the ground plate 30 to the conductive shields 40, 41, a fault signal can be transmitted inside and outside the connector housing. It forms a branch path that disperses electromagnetic wave energy, and also reflects and absorbs electromagnetic wave energy, providing an extremely excellent shielding effect against electromagnetic interference. Reflection takes place at the surface of the conductive shields 40, 41 and absorption takes place at the ground plate 30.
This is done internally.

It is also convenient if the ground plate 30 is held sufficiently close to all the contacts 50, and the complete grounding distance formed by the ground plate 30 is in the direction across the ground plate 30. Since the grounding plate 30 is located at the center of the connector housing, a more perfect grounding effect can be obtained compared to the prior art. In other words, in the prior art, the grounding effect was often provided by, for example, a screw installed on the opposite side of the connector. The distance to the ground was not considered important. Therefore, the distance for complete grounding is considerably longer than in the present invention, increasing the probability of stray inductance causing serious electromagnetic interference. The invention therefore maximizes the coverage area of the ground plate 30;
Minimizing the distance between contacts 50, embedded electrical elements 70, and full grounding seeks to eliminate or substantially reduce the chance of stray inductance occurring.

Due to the above features of the present invention, the built-in electrical element 70, for example a delicate filter element such as the chip capacitor 70, must be fixedly attached to the contact 50 by soldering, gluing or other methods. This overcomes the problem of the prior art that the contact 5 must be attached by the conductive spring piece 60.
0 and the delicate installed electrical element 70, even a slight axial force from the contact 50 can prevent the installation. Even in cases where the electric element 70 may be mishandled, undesirable situations can be prevented from occurring.

In short, the conductive spring piece 60 has several features that overcome the problems of the prior art, and the conductive spring piece 60 allows the integrated electrical element 70 to be attached without soldering, gluing or laser welding. By simply inserting it freely into the connector 1, stable and maximum electrical connectivity can be maintained with respect to the grounding plate 30 and the contacts 50.
Moreover, it is suitable for implementing a flexible manufacturing system in which semi-finished connector components are stored as inventory and later a final product can be easily constructed based on the user's special specifications.

[Assembling method according to the present invention] Below, FIG.
To explain the assembly method of the present invention with reference to FIG. 4, a connector component part 1b as a semi-finished product of the connector 1 that can be stored as inventory is manufactured, and a finished product of the connector 1 is manufactured according to the user's arrangement based on the user's own design specifications. The connector assembly sequence using the flexible manufacturing system can be roughly divided into two stages. That is, first the connector arrangement is manufactured as a stockable semi-finished product, i.e. the connector component 1b, and then the user's A wide variety of contacts 50 and chip-type built-in electrical elements 70 are selectively and easily inserted into the connector component 1b according to design specifications. That is, this user configuration can be easily and inexpensively performed with off-the-shelf contacts 50 and built-in electrical elements 70 without the need for gluing, welding, or soldering, and is a feature of the connector assembly of the present invention. The preliminary steps are as follows.

(A) preparing a pre-insulator 10 having a plurality of first passages 11 penetrated therein; and (B) providing a plurality of first passages 21 corresponding to the first passages 11;
(C) preparing a rear insulator including a second passage 22 formed parallel to the first passage 21 and communicating with the first passage 21; (C) a front insulator 10 and a rear insulator 20; (D) installing the ground plate 30 across the first passages 11, 21 and the second passage 22;
(E) adhering the ground plate 30 to the front insulator 10 and the rear insulator 20 by suitable adhesive or adhesive means to form an intermediate insert structure 1a; A step of installing the front conductive shield 40 on the front half, that is, the front insulator 10, and (F) the insertion structure 1a.
In other words, the rear conductive shield 41 is attached to the rear insulator 20.
(G) for example, a suitable connection means 4;
00, the tab 401 folded down below the front conductive shield 40 (see FIGS. 1 and 2) holds the rear conductive shield 41, and the bolt 402 illustrated in FIG.
, nuts 403 are attached to mounting holes 404 and 405 (Fig.
), and firmly tighten the front conductive shield 40 and the rear conductive shield 41 to remove the connector component 1.
The process of manufacturing connector component 1b as a semi-finished product forms the preliminary stage of a flexible manufacturing system, stores this connector component part 1b as an inventory item, and later arranges and configures the finished product of connector 1 based on the user's own design specifications. do.

[0036] When the user's instructions regarding the correct arrangement of the connector 1 are received, the following steps for arranging and configuring the custom-made connector 1 from the semi-finished product, that is, the connector component part 1b, are developed.

(H) a step of selectively inserting a built-in electric element 70 having a function specified by the user, such as a chip capacitor 70, into the second passage 22 of the rear insulator 20; A conductive spring piece 60 in the second passage 22

(J) inserting the contact 50 into the first passage 21 adjacent to the selected second passage 22 to the normal position;
The step of forming the contacts 50 to make a good electrical connection with the inserted embedded electrical element 70 via the conductive spring piece 60 constitutes the later stage of the flexible manufacturing system. At this time, in step (I), the rear flat plate surface 61 is
After passing the step 221 of the passage 22, it elastically expands rearward, so that the free end of the rear flat plate surface 61 passes through the step 221.
The built-in electrical element 70 is firmly held without relying on welding or adhesion, and the electrical connection between the grounding plate 30 and the contact 50 is made stable and maximized. Since the conductive spring piece 60 also has a structure that prevents the transmission of torsional force from the contact 50, as described above, a slight axial force of the contact 50 may damage the built-in electric element 70 or cause undesirable damage. Even if there is a concern that a situation may occur, the built-in electrical element 70 is sufficiently protected. In addition, the process (J
), after each contact 50 reaches the normal position, its anterior lateral protrusion 51 elastically expands and comes into close contact with the step 211, so that backward movement is suppressed and the posterior lateral protrusion 51 of each contact 50 is Since forward movement is also suppressed by the close contact of the protrusion 52 with the step 212, each contact 50 is firmly fixed at a predetermined position in the first passages 11, 21. Note that the order of steps (I) and (J) is changed, and the contact 50 is placed first in the first passage 11.
, 21 and then inserting the conductive spring piece 60 into the second passage 22.

Embodiment 2 Referring to FIGS. 5 and 6, a connector 1 according to a second embodiment of the present invention will be described. A front conductive shield 40 that covers only the front insulator 10 is provided, and a ground plate 30 is provided. In order to completely connect to the front conductive shield 40, the side shape of the rear insulator 20 and the side shape of the ground plate 30 are slightly modified as shown. In other words, both ends of the rear insulator 20 are connected to the ground plate 3.
0 and the front conductive shield 40, and is formed to shield the ground plate 30 and the front conductive shield 40 from the surroundings, and to effectively block stray electromagnetic interference. ing.

In FIG. 5, since the front and rear insulators 10 and 20 are symmetrical, the first
The contacts 50 can be inserted into the passages 11 and 21 with the left and right sides upside down compared to the first embodiment.
When the contacts 50 are inserted in opposite directions, the two rows of contacts 50 are convenient for solder cup terminals facing each other, and when the contacts 50 are inserted in the same direction, they are convenient for L-shaped terminals. Then, the second passage 22 of the rear insulator 20 is connected to the first passage 2.
1, it becomes easier to distinguish the insertion positions of the contact 50, the conductive spring piece 60, and the built-in electric element 70.

Furthermore, the embedded electrical element 70 is not limited to the chip capacitor 70, but may include other types of chip elements, such as resistors, varistors, diodes, or similar embedded electrical elements, according to the needs of the user. It is also possible to incorporate electrical elements originally provided in the printed electrical circuit into the connector 1 of the present invention as built-in electrical elements 70, as long as the system functionality is not changed.

[0041] In the present invention, there is no need for the connector manufacturer to keep a large number of various connectors in stock. Because the connectors are manufactured as semi-finished products in accordance with the flexible manufacturing system, there is no need for long waiting times to produce the connectors to order. In terms of time and cost for arranging and configuring the final product, the final product can be provided by simply inserting contacts and integrated electrical elements (capacitors or other necessary chip elements) into the corresponding channels for the semi-finished product. This results in a highly effective flexible manufacturing system.

Of course, the present invention is not limited to the embodiments described above, but can also be applied to connectors having L-shaped terminals and solder cup terminals, for example.
